Digital Signal Processing (DSP) Project Ideas with Abstract

2012-02-07T23:13:00.000-08:00

I have collected a few interesting project topics in Digital Signal Processing with abstracts for you. Read it and do your project.

1.TRACKING AND COUNTING PEOPLE IN VISUAL SURVEILLANCE SYSTEMS [IEEE 2011]

ABSTRACT The greatest challenge on monitoring characters from a monocular video scene is to track targets under occlusion conditions. In this work, we present a scheme to automatically track and count people in a surveillance system. First, a dynamic background subtraction module is employed to model light variation and then to determine pedestrian objects from a static scene. To identify foreground objects as characters, positions and sizes of foreground regions are treated as decision features. Moreover, the performance to track individuals is improved by using the modified overlap tracker, which investigates the centroid distance between neighboring objects to help on target tracking in occlusion states of merging and splitting. On the experiments of tracking and counting people in three video sequences, the results exhibit that the proposed scheme can improve the averaged detection ratio about 10% as compared to the conventional work.

2. DESIGN AND OPTIMIZATION OF THE MOVING OBJECT DETECTING SYSTEM BASED ON BLACKFIN DSP [IEEE 2010]

Abstract – Based on Blackfin DSP, we design and implement a compact moving object detecting and video recording system. The background subtraction algorithm is applied to the system to detect the moving objects. And when there is any object being detected, the frames containing the moving objects will be recorded automatically. In order to improve the accuracy of the detecting results, in this paper, instead of using the median filter, we design the block filtering algorithm to filter the noise with the simply connected block region, since the block filtering algorithm needs far less amount of computation than the median filtering algorithm. Further, in order to improve the detecting speed, based on the memory configuration of the system, a new block based parallel data processing mechanism is proposed, in which the external memory data to be processed is moved into the internal memory space in advance that greatly reduces the external memory access requests of the DSP core, thus good parallel data processing and transmission is achieved. The results of the experiments demonstrate that the block filtering algorithm is more suitable for a real time system than the median filter, because the block filtering algorithm improves the filtering efficiency greatly by reducing the amount of filtering computation and also works with satisfying statistical accuracy. In addition, the results of the experiments also show that the block based parallel data processing mechanism is highly effective in improving detecting speed and contributes to a more efficient parallel detecting system.

3. AN IMPROVED MEDIAN FILTERING ALGORITHM COMBINED WITH AVERAGE FILTERING [IEEE 2011]

Abstract—To solve the contradiction between the noisereducing effect and the time complexity of the standard median filter algorithm, the paper proposed an improved median filter algorithm combined with average filtering. According to the correlation of the image, the algorithm adaptively resizes the filter mask according to noise levels of the mask. According to the sorting results of the selected pixel values in the neighborhood, the algorithm uses the median to replace the original pixel. Experimental results show that the improved algorithm can effectively reduce time complexity and has better noise-reducing effect than the standard median filter algorithm. It has a good application prospect in image processing.

4. RESEARCH AND IMPLEMENTATION OF INFORMATION HIDING BASED ON RSA AND HVS [IEEE 2011]

Abstract: To better protect the security of information, this paper proposed an information transmission scheme which combined the cryptosystem and information hiding. The scheme pretreated the information firstly by making use of the RSA arithmetic which belongs to the public key cryptosystem, and then took advantage of the improved LSB which based on the Human Visual System to make the cryptograph hid in the 24 bits BMP image and transmitted it. The embedding and extracting process of secret information in the scheme were discussed in detail. Also, the result of information hiding achieved by this scheme was given. The principle of the scheme is simple, and it is easy to implement. The experimental result suggests that the scheme is efficient and has good practical value.

5. PERFORMANCE ANALYSIS OF INTEGER WAVELET TRANSFORM FOR IMAGE COMPRESSION [IEEE 2011]

Abstract— For image compression, it is very necessary that the selection of transform should reduce the size of the resultant data as compared to the original data set .In this paper, a new lossless image compression method is proposed. For continuous and discrete time cases, wavelet transform and wavelet packet transform has emerged as popular techniques. While integer wavelet using the lifting scheme significantly reduces the computation time, we propose a completely new approach for further speeding up the computation. First, wavelet packet transform (WPT) and lifting scheme (LS) are described. Then an application of the LS to WPT is presented which leads to the generation of integer wavelet packet transform (IWPT). The proposed method, Integer Wavelet Packet Transform (IWPT) yields a representation which can be lossless, as it maps an integer valued sequence onto the integer valued coefficients. The idea of Wavelet Packet Tree is used to transform the still and color images. IWPT tree can be built by iterating the single wavelet decomposition step on both the low-pass and high-pass branches, with rounding off in order to achieve the integer transforms. Thus, the proposed method provides good compression ratio.

6. DESIGN OF A COLOR IMAGE FUSION SYSTEM BASED ON DSP AND FPGA [IEEE 2010]

Abstract—In this paper, a color image fusion system based on DSP and FPGA is introduced .In the system, TMS320DM642 is used as the kernel processor to finish the images fusion arithmetic, storage and display. FPGA, which has the ability to control the logic of image capturing, is used as the assistive processor. The experiment shows that this technology can obtain color fusion image.

7. THE PORTABLE WIRELESS AERIAL IMAGE TRANSMISSION SYSTEM BASED ON DSP [IEEE 2010]

Abstract-The paper provides portable digital aerial image system based on Blackfin DSP. The system includes the aeromodellingcarrier part and the ground control part. The image transmission between the two parts realized with Nordic Semiconductors RF transceiver nRF24L01. The aeromodelling-carrier part takes pictures using CMOS image sensor and compresses data by ADSPBF531, then sends them to ground part wirelessly. The ground control center based on ADSP-BF533 supervises images real time and samples data. After relevant subsequent image processing and compressing, the final image is saved locally. In controllable range, the system can take pictures anyplace and any angle, can lock object neatly. This system features double DSP architecture so it can transmit and process image very fast. It is small, light, low power consumption and low cost. It is easy for single taking and operation, so has good application prospect in field reconnaissance, traffic surveillance, city layout and the situation of bad weather or a disaster and so on.

8.DETECTING BACKGROUND SETTING FOR DYNAMIC SCENE [IEEE 2011]

Abstract – Processing Real-Time image sequence is now possible because of advancement of technological developments in digital signal processing, wide-band communication, and high-performance VLSI. With the developments in video technology, the surveillance system can be built with some low cost gadget such as the web-camera. In this modern life with increasing number of crime rate, people in society need for security and safety; video surveillance has become important reason to oppose threats of crime and terrorism. The most fundamental part of surveillance is foreground detection, which is retrieval of an object of interest. The object of interest can remodel by common background subtraction technique. There is some problem arises by using this technique, where because of variation of light source, the background constantly changes. The intensity of pixel changes throughout the object detection takes place. Intensity of pixel value changes leads to improper foreground detection, the background detected as foreground object. This paper proposes a method to model and update the background of the scene by intersection solving method.

9.A VIEW ON LATEST AUDIO STEGANOGRAPHY TECHNIQUES [IEEE 2011]

Abstract—Steganography has been proposed as a new alternative technique to enforce data security. Lately, novel and versatile audio steganographic methods have been proposed. A perfect audio Steganographic technique aim at embedding data in an imperceptible, robust and secure way and then extracting it by authorized people. Hence, up to date the main challenge in digital audio steganography is to obtain robust high capacity steganographic systems. Leaning towards designing a system that ensures high capacity or robustness and security of embedded data has led to great diversity in the existing steganographic techniques. In this paper, we present a current state of art literature in digital audio steganographic techniques. We explore their potentials and limitations to ensure secure communication. A comparison and an evaluation for the reviewed techniques is also presented in this paper.

10.A REAL-TIME VISION SYSTEM FOR NIGHTTIME VEHICLE DETECTION AND TRAFFIC SURVEILLANCE(IEEE MAY 2011)

Abstract—This paper presents an effective traffic surveillance system for detecting and tracking moving vehicles in nighttime traffic scenes. The proposed method identifies vehicles by detecting and locating vehicle headlights and taillights using image segmentation and pattern analysis techniques. First, a fast bright-object segmentation process based on automatic multilevel histogram thresholding is applied to effectively extract bright objects of interest. This automatic multilevel thresholding approach provides a robust and adaptable detection system that operates well under various nighttime illumination conditions. The extracted bright objects are then processed by a spatial clustering and tracking procedure that locates and analyzes the spatial and temporal features of vehicle light patterns, and identifies and classifies moving cars and motorbikes in traffic scenes. The proposed real-time vision system has also been implemented and evaluated on a TI DM642 DSP-based embedded platform. The system is set up on elevated platforms to perform traffic surveillance on real highways and urban roads. Experimental results demonstrate that the proposed traffic surveillance approach is feasible and effective for vehicle detection and identification in various nighttime environments.

Level measurement using Gauge Glass Technique:

2012-01-20T00:04:00.000-08:00

A sight glass (also called a gauge glass) is used in the liquid level measurement. It is used for continuous indication of liquid level within a tank or vessel.

Construction and working of Gauge Glass Technique:

A sight glass instrument consists of a graduated tube of toughened glass which is connected to the interior of the tank at the bottom whose water level is to be measured. The image below shows a simple sight glass for an open tank in which the liquid level in the sight glass matches the level of liquid in the tank.

As the level of liquid in the tank rises and falls, the level in the sight glass also rises and falls accordingly. Thus by measuring the level in the sight glass, the level of liquid in the tank is measured.

When it is desired to measure a liquid level with the liquid under pressure or vacuum, the sight glass must be connected to the tank at the top as well as at the bottom, otherwise the pressure difference between the tank and the sight glass would cause false reading. In this case, the glass tube is enclosed in protective housing, and the two valves are provided for isolating the gauge from the tank in case of breakage of the sight glass. The smaller valve at the bottom is provided for blowing out the gauge for cleaning purpose.

Pressure balance is obtained at any points in the fluid which are at equal distances above or below some reference. If the liquids are subjected to the some external pressure and have the same specific gravity, the level will be the same in both vessels.

The image below shows a high pressure sight glass in which measurement is made by reading the position of liquid level on the calibrated scale. This type of sight glass in high pressure tanks is used with appropriate safety precautions. The glass tube must have a small inside diameter and a thick wall.

When the liquid in the tank is under some external pressure, the pressure can be nullified by connecting the sight glass as indicated.

Remote indication

Liquid level in either open tank or closed tank can be measured by sight glass or gauge glass technique. It can be controlled by the operator in the control room by means of monitoring the sight glass fixed at different places of tank with the help of CCTV system. OCD camera is focused at the sight glass or gauge glass and viewed in the control room through a monitor. The image below illustrates the block diagram of the remote indication of level measurement.

Ranges of gauge glass:

The standard practice is not to go in for a glass tube of more than 900mm length. In case the height of the tank is more than 900mm, two or more sight glass level gau ges are provided at different levels. This type of gauge is made to withstand pressures of 150 kg/cm^2 of steam pressures at 250’C or 450kg/cm^2.

Advantages of gauge glass:

Direct reading is possible.
Special designs are available for use upto 3000’c and 650 kg/cm^2.
Glassless designs are available in numerous materials for corrosion resistance.

Disadvantages of gauge glass:

The main disadvantage is that, it is read where the tank is located which is not always convenient.
Since sight glasses are located outside the tanks, the liquid in the sight glass may freeze in clod weather even though the liquid inside the tank does not, and thus, it may cause error in the reading.
Heavy, viscous liquids or liquids containing material which fall out of solution and clog the tube cannot be measured satisfactory by sight glass.
Overlapping gauges needed for long level spans.
Accuracy and readability depends on cleanliness of glass and fluid.

Data Acquisition System Based On Labview For Abs Dynamic Simulation Test Stand

Abstract - Anti-Lock Braking System (ABS) has become a standard configuration for vehicles. We created a virtual environment to approximate the external conditions by using ABS dynamic simulation test stand to test the performance of ABS. Measurement and analysis of the test stand are two important issues for ensuring the high quality of ABS. In this paper, an automatic measurement and examination platform based on powerful software LabVIEW is designed and implemented. LabVIEW is easy for monitoring and data acquisition. Parameters of the test stand are recorded and analyzed simultaneously by applying LabVIEW. In order to make the testers immerse in the movement environment, we created an animation interface which can supply real-time driving scene according to the running state of the test stand. The complex animation of driving scene is carried out with programming.

Pc-Based System For Level Transducer Interfacing

Abstract— Many applications rely on accurate readings from level transducers for a correct behaviour of complex systems. Large chemical and food industry plants employ large numbers of such devices which have to generate a correct behaviour and provide an accesible reading of the data. This paper presents an application for level measurement using appropiate signal conditioning and data aquisition hardware. We start by presenting the physical principles of level transducers and their classification. Signal conditioning, as an essential factor to obtaining correct readings is also highly regarded. The advantages of PC-based systems are then observed (compatibility, low-cost) along with the additional benefits brought by developing the software application in a graphical programming environment such as LabVIEW. We describe in depth the hardware system involved and the functionality of the written software. We add considerations regarding the performance of the overall system including hardware and software features. One interesting fact is that we have run the data aquistion application in an virtualized environment so we are able to make a performance-wise comparison among the virtualized and non-virtualized scenarios. The main output of the paper is the a software application for the measurement of the liquid level in a knownvolume tank, which can be easily deployed across multiple computers due to its stand-alone characteristic. It is an appropiate tool for teaching and research projects and can easily be extended for the more stringent requirements of industrial tasks, such as reliabilty and compatibility with existing industrial systems.

A Multisensor Intelligent Device For Real-Time Multiphase Flow Metering In Oil Fields

Abstract—In this paper, a new multiphase flow metering device for real-time measurement of oil, gas, and water flow rates is presented. It is composed of several electrical and acoustic sensors whose signals are digitalized and processed by a multilayer neural network. This latest uses the physical models of multiphase fluids to reduce the complexity of the parameter space while improving its accuracy. Furthermore, to overcome the uncertainties of the electrical sensors in the range of 40%–60% and above 90% water- cut (i.e., ranges where most of the multiphase flow meter fail), two rings of high- and low-frequency ultrasonic sensors are used for low and high gas fractions, respectively. The results of experiments that have been conducted in an in-house laboratory-scale multiphase flow loop show that real-time classification for up to 90% gas fraction can be achieved with less than 10% relative error.

A Laboratory Testbed For Embedded Fuzzy Control

This paper presents a novel scheme called “Laboratory Testbed for Embedded Fuzzy Control of a Real Time Nonlinear System.” The idea is based upon the fact that project-based learning motivates students to learn actively and to use their engineering skills acquired in their previous years of study. It also fosters initiative and focuses students attention on authentic realworld problems. At the same time, it enhances their learning. Students gain hands-on experience and improve their skills in product development, self-directed learning, teamwork, and project management. There has been a tremendous rise in the popularity of intelligent control techniques like fuzzy logic for use in industrial control applications in recent times. These techniques, which were primarily conceived for nonlinear control applications, are best implemented using embedded controllers, which can use their capabilities to the maximum. While courses in electrical and computer engineering cover several areas like digital and analog integrated circuits, microprocessors and control Systems, and process control, few of these integrate all these areas with focus on the application of intelligent techniques in real-time systems. Also, there is a growing need in industry for engineers who can perform software design and system integration for various applications in embedded control. This paper aims at developing such a practical task as one of the major projects in the eighth semester of the program offered by the Instrumentation and Control Engineering (ICE) Department of Netaji Subhas Institute of Technology (NSIT), Delhi University, India, to design a real-time embedded controller implementing an intelligent control technique, fuzzy logic, for control applications. These applications might, for example, be level control, flow control, or pressure control. The paper discusses an example of a real-time pressure control system for which a microcontroller- based fuzzy proportional-integral-derivative (PID) controller has been simulated and implemented with satisfactory results.

Application Of Prognostic And Health Management Technology On Aircraft Fuel System

Prognostic and Health Management (PHM), which could provide the ability of fault detection (FD), fault isolation (FI) and estimation of remaining useful life (RUL), has been applied to detect and diagnose device faults and assess its health status, with aiming to enhance device reliability, safety, and reduce its maintenance costs. In this paper, taking an aircraft fuel System as an example, with virtual instrument technology and computer simulation technology, an integrated approach of signal processing method and model-based method is introduced to build the virtual simulation software of aircraft fuel PHM system for overcoming the difficulty in obtaining the failures information from the real fuel system. During the process of constructing the aircraft fuel PHM system, the first step is to analyze the fuel system failure modes and status parameters that can identify the failure modes. The main failure modes are determined as joints looseness, pipe broken, nozzle clogging, and fuel tank leakage. The status parameters are fuel pressure and fuel flow. Then, the status parameter model is constructed to imitate the behavior of sensor which detecting fuel system status. On this basis, utilizing the signal processing module provided by Labview software, the outputs from the virtual sensors, which collect the failure data, are processed to realize the simulation of failure detection and failure diagnosis. All the result shows that the virtual simulation software well accomplishes the task of the aircraft fuel system failure detection and diagnosis.

PACED BREATHING CONTROLLER USING LABVIEW

Paced breathing devices are designed and used for exactly that... paced breathing. Often when a researcher is conducting an experiment that requires analyzing biological signals, the number of variables are reduced by keeping all the subject’s rate of breaths per minute (BPM) the same. Presently there exists both software and hardware that serves the purpose of this task. This project has combined both of these to build a new apparatus using the latest technology. Instead of a hardware device which is difficult to manipulate once constructed, the software package LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is used to construct this device. LabVlEW is a icon driven package which parallels actual electrical components. If the situation arises in which changes need to be made, they can be performed relatively easily assuming there is some knowledge of the software at hand. The convenience of this arises because manipulations can be made without the use of a soldering iron or any other tool with the exception of a mouse.

Labview-Based Universal Battery Monitoring And Management System

In this paper the main principles and the general structure of battery monitoring and management systems (BMS) are explained. Furthermore, a newly developed, highly accurate and inexpensive data acquisition system for BMS is presented.

Following the discussion of the measuring hardware, a LabView realization of a universal BMS software is described in detail. Due to the flexible design of the LabView BMS, the system is able to perform control and surveillance activities for any kind of battery application and battery technology (e.g. Pb, VRLA, NiCd, NiMH etc.). The BMS was originally designed for VRLR batteries in uninterruptible power supply systems (UPS), but was also tested in electric vehicles (VW CityStromer, BMW).

Development Of A Virtual Instrument For Data Acquisition And Analysis Of The Phonocardiogram

A medical virtual instrument has been developed to acquire and analyze the phonocardiogram (PCG), the heart sound and murmur signal. This instrument consists of a Pentium 200 computer running Windows95, equipped with LabVIEW software and a plug-in data acquisition board, and a two-channel custom designed bio-signal preamplifier. The bio-signal preamplifier allows the data acquisition board to acquire both the PCG and the electrocardiogram (ECG). LabVIEW software modules have been developed to create virtual instrument’s front panels for the following functions: to manage patient information and data files, to capture and display current ECG and heart sound signals while saving or analyzing previous acquired signals, to perform the spectral and time-frequency analysis of the heart sounds and murmurs, and to review the previous recordings. This instrument can be used to display the PCG and to analyze the individual heart sound and murmur for the detection of heart valve diseases. It can also be used to analyze the carotid bruit for the diagnosis of carotid artery stenosis. This study demonstrated that a LabVIEW-based medical virtual instrument provides a low-cost, reliable, and flexible solution for data acquisition and analysis of the PCG and carotid bruit.

Effective Simulation Of Signals For Testing Ecg Analyzer

In this paper the solution of the specialized measuring system for electrocardiography (ECG) signal recording and introductory recognition is presented. The project aims at designing the complete PC-based Virtual Instrument as a “testing platform” for acquisition, processing, presenting, and distributing ECG data. A new design involving the latest technique in signal simulation was developed to create a controllable model of the electrocardiography signal. Then it was implemented for testing of the developed QRS detection algorithm, based on the time-frequency analysis method. The processing stage involving discrete wavelet transform was used to detect QRS complexes in the ECG signal. By using the controlled signal model and the real ones, the algorithm was shown to be advantageous in reducing ventilation artifacts and motion noise, resulting in good accuracy.

Remote Calibration Using Mobile, Multiagent Technology

Instrument calibration, though unavoidable, is extensively time and resource consuming. It often involves a distinct layer of data management and security. Since many of the available digital instruments are provided with communication interfaces, one can build a remote calibration system from the actual hardware and a computing unit with Internet connection capabilities. This paper, after showing a simple client–server architecture, discusses how the use of mobile, multiagent techniques is expected to solve most of the security issues, working as well and effectively as a traditional, agent-free client–server architecture.

Fuzzy logic control

2012-01-02T23:11:00.000-08:00

Introduction to Fuzzy logic control

In fuzzy logic control the experience of human process operator, is incorporated in design of the controller. This logic controller provides a means of converting a linguistic control strategy based on operates knowledge into an automatic control strategy, linguistic variables are quantities like high, medium, low, etc., fuzzy logic is multivalued logic which enhances man machine interaction. Fuzzy logic is implemented using fuzzy sets.

A set is a well defined collection of objects. A crisp set is one which identities whether the object is present in that collection or not.

The function A(x) is such that

That is the object x will either belong to set or not.

Fuzzy set is one that allows partial membership of object in that set here the degree to which a variable is member of a given set is indicated.

Let X be a set and x is an element of X. then fuzzy set A is given by

A = {A(x)/x} ; x E X

A(x) given degree of membership and has a range of 0 to 1. it indicates that the degree of membership of an element x in a fuzzy set A ranges from 0 to 1 where 0 indicates null membership. 1 indicates full membership, and intermediate values represent partial membership.

Advantages of Fuzzy logic control:

Relates input to output in linguistics terms; easily understood.
Cheaper because they are easier to design.
Increased robustness.
Can achieve less overshoot & oscillation.
Can achieve steady state in a shorter time interval.
Simplify knowledge acquisition & representation.

Sensors Used in Instrumentation and Control

2011-12-07T21:23:00.000-08:00

Ammeter - A meter to indicate electrical current. It is normally part of a DMM.

Bellows - This is a flexible volume that will expand or contract with a pressure change. This often looks like a cylinder with a large radius (typ. 2") but it is very thin (type 1/4"). It can be set up so that when pressure changes, the dis-placement of one side can be measured to determine pressure.

Bourdon tube - Widely used industrial gage to measure pressure and vacuum. It resembles a crescent moon. When the pressure inside changes the moon shape will tend to straighten out. By measuring the displacement of the tip the pressure can be measured.

Chromatographic instruments - laboratory-type instruments used to analyze chemical compounds and gases.

Inductance-coil pulse generator - transducer used to measure rotational speed. Output is pulse train.

Interferometers - These use the interference of light waves 180 degrees out of phase to determine distances.
Typical sources of the monochromatic light required are lasers.

Linear-Variable-Differential transformer (LVDT) electromechanical transducer used to measure angular or linear displacement. Output is Voltage

Manometer - liquid column gage used widely in industry to measure pressure.

Ohmmeter - meter to indicate electrical resistance.

Optical Pyrometer - device to measure temperature of an object at high temperatures by sensing the brightness of an objects surface.

Orifice Plate - widely used flowmeter to indicate fluid flow rates

Photometric Transducers - a class of transducers used to sense light, including phototubes, photodiodes, phototransistors, and photoconductors.

Piezoelectric Accelerometer - Transducer used to measure vibration. Output is emf.

Pitot Tube - Laboratory device used to measure flow.

Positive displacement Flowmeter - Variety of transducers used to measure flow. Typical output is pulse train.
Potentiometer - instrument used to measure voltage.

Pressure Transducers - A class of transducers used to measure pressure. Typical output is voltage. Operation of the transducer can be based on strain gages or other devices.

Radiation pyrometer - device to measure temperature by sensing the thermal radiation emitted from the object.

Resolver - this device is similar to an incremental encoder, except that it uses coils to generate magnetic fields. This is like a rotary transformer.

Strain Gage - Widely used to indicate torque, force, pressure, and other variables. Output is change in resistance due to strain, which can be converted into voltage.

Thermistor - Also called a resistance thermometer; an instrument used to measure temperature. Operation is based on change in resistance as a function of temperature.

Thermocouple - widely used temperature transducer based on the Seebeck effect, in which a junction of two dissimilar metals emits emf related to temperature.

Turbine Flowmeter - transducer to measure flow rate. Output is pulse train.

Venturi Tube - device used to measure flow rates.

i hope you enjoyed this post, comment me for any clarification.

Spiral bimetallic thermometer

2011-12-02T04:18:00.000-08:00

Basic principle of Spiral bimetallic thermometer

When a bimetallic spiral fixed at one end and free at the other end is subjected to a temperature change, the free end of the bimetallic spiral deflects proportional to the change in temperature. This deflection becomes a measure of the change in temperature.

Description of Spiral bimetallic thermometer

The main parts of a spiral bimetallic thermometer are as follows:
A bimetallic spiral which is fixed at one end to the body of the instrument and free at its other end.
To the free end of the bimetallic spiral is attached to a free floating shaft.
One end of the shaft is mounted in a fraction less arrangement and its other end is connected to a pointer which sweeps over a temperature calibrated circular dial graduated in degrees of temperature.

Operation of Spiral bimetallic thermometer

When a temperature of a medium is to be measured, the bimetallic thermometer is introduced into the medium for a length ‘L’

The bimetallic spiral senses the temperature and expands resulting in a deflection at its free end.

This deflection at the free end of the bimetallic spiral rotates the free floating shaft connected to it. When the free floating shaft rotates, the pointer attached to the shaft moves to a new position on the temperature calibrated dial including the measured temperature.

Helix Bimetallic Thermometer

This article is a continuation of my previous post on Bimetallic Thermometer

Basic principle of Helix Bimetallic Thermometer:

When a bimetallic helix fixed at one end and free at the other end is subjected to a temperature change, the free end of the bimetallic helix deflects proportional to the change in temperature. This deflection becomes a measure of the change in temperature.

Description of Helix Bimetallic Thermometer:

The main parts of a helix bimetallic thermometer are as follows:
A bimetallic helix which is fixed at one end to the body of the instrument and free at its other end.
To the free end of the bimetallic helix is attached a shaft.
One end of the shaft is mounted in friction less arrangement and its other end is connected to a pointer which sweeps over a temperature calibrated circular dial graduated in degrees of temperature.

Operation of Helix Bimetallic Thermometer:

When temperature of a medium is to be measured, the bimetallic thermometer is introduced into the medium for a length “L”
The bimetallic helix senses the temperature and expands resulting in a deflection at its free end.
This deflection at the free end of the bimetallic helix rotates the shaft connected to it. When the shaft rotates , the pointer attached to the shaft moves to a new position on the temperature calibrated dial indicating the measured temperature.

Ultrasonics – Introduction.

2011-11-26T21:48:00.000-08:00

Vibrations upto 20,000 cycles can be heard by human beings and so, the frequency range upto 20KHz is called sonic frequency. Sound waves do not belong to the electromagnetic wave family like heat and light. As such, study of sound waves is not exactly an electronic branch. However most of the ultrasonic sound waves find very valuable industrial applications as flaw direction, submarine communication, electronic soldering and welding.

Ultrasonics is today applied in medical diagnosis (echo-scanning) as an alternative to X-ray scanning. Production of ultrasonic sound waves involves use of electronic oscillators called transducers. Use of ultrasonic waves does not involve harmful wave radiation. Radiation is present in other methods for the applications mentioned above. Hence ultrasonics is a welcome substitute for electromagnetic waves in many industrial applications.

Properties of ultrasound.

The ultrasonic waves travel in different media with different velocities. In air it travels at 330m/sec. The velocities in liquids and solids range from 1200m/s to 4000m/s respectively. The property of a medium to conduct ultrasonic waves is represented in its acoustic impedance. When ultrasound travels through a homogeneous medium there is not change of velocity or wavelength and hence it essentially continues in a straight line. When the ultrasound beam reaches an interface between two different media, it undergoes reflection and refraction.

The reflected wave may be termed as the ultrasonic echo. The echoes produced by large objects with smooth surface are specular echoes. Much energy is returned by these specular echoes. Echoes from small objects with irregular shapes are called scattered echoes. When ultrasound gets reflected irregularly in multiple directions, only a small part of ultrasonic energy returns to the source. Through analysis of reflected waves leads to several useful applications in industry and medicine. The properties of ultrasound are summed up as follows:

Ultrasound

Can be directed into a beam.
Obeys laws of reflection and refraction.
Is reflected by small objects.
Permits recording of clear echoes from interface that are approximately 1 mm part.

A Complete Note on Difference between Lab View, PLC and DCS

2011-11-02T00:59:00.000-07:00

Yesterday, i receive a question from one of my facebook fan asking " sir could u please say the difference between labview and plc and dcs "

As far as i know Lab View is completely different from DCS and PLC, Labview is a software.

LabVIEW is a graphical programming environment used by millions of engineers and scientists to develop sophisticated measurement, test, and control systems using intuitive graphical icons and wires that resemble a flowchart. It offers unrivaled integration with thousands of hardware devices and provides hundreds of built-in libraries for advanced analysis and data visualization – all for creating virtual instrumentation. The LabVIEW platform is scalable across multiple targets and OSs, and, since its introduction in 1986, it has become an industry leader.

A distributed control system (DCS) refers to a control system usually of a manufacturing system, process or any kind of dynamic system, in which the controller elements are not central in location (like the brain) but are distributed throughout the system with each component sub-system controlled by one or more controllers. The entire system of controllers is connected by networks for communication and monitoring.

A programmable logic controller (PLC) or Programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory. A PLC is an example of a hard real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result.

The differences between DCS and PLC are: DCS (Distributed Control System) is a CONTROL SYSTEM that works using several controllers and coordinates the work of all these controllers. Each controller is handling a separate plant. This controller is referred to the PLC.

The PLC (Programmable Logic Controller) is a CONTROLLER which can be re-program back. If the PLC is only a stand-alone and not combined with other PLCs, it is called as DDC. It means PLC is a sub system of a large system called DCS.

What’s difference between PLC and DCS by its definition:
PLC is a controller or processor that can be programmed (programmable) whose function is to run (execute) logic functions. Logic means the discrete / sequence function is usually handled by the relay. From the beginning of the vendors who carry the name of the PLC is engaged in the business discrete / sequence control.

Regardless of the distributed control system (as opposed to the DDC = Direct Digital Control) is categorized as a DCS. In DDC all system controls are done in the central processor so that if it failed, the entire control plant will also failed. DDC is mostly used as a Regulatory Control. And from the beginning vendors that carry the name of DCS is to use the product as a regulatory control.

Different in functionality means that the DCS and PLC can not be implemented on the same application.
1. DCS is not a large PLC. Because system architecture of DCS and PLC are different.
2. DCS is not PLCs that integrated into one large system. "Controller" in the PLC is more intended as a "Logic Controller", while “Controller” in the DCS is more intended as a "Process Controller".
3. Both DCS and PLC is a configurable and reconfigurable.
