ZIGBEE BASED WIRELESS DC MOTOR SPEED & DIRECTION CONTROL
bharadwaj874@gmail.com
ABSTRACT : Wireless sensor networks have been very popular research field for the last couple of years. ZigBee is a new technology now being deployed for wireless sensor networks. ZigBee is a low data rate wireless network standard defined by the ZigBee Alliance and based on the IEEE 802.15.4.The ZigBee wireless network has some advantages compared with other wireless networks, it has the characteristics of low power, low price, highly secured and reliable, so implementing a remote motor control and monitoring system proves to have a good cost performance ratio.
This paper presents the implementation of a wireless sensor actor network (point to point) to control the speed of a DC motor from a remote location. Pulse Width Modulation technique provides the actual control. A feedback to measure the current speed is setup using Infra Red Sensor and fed to PIC16F877 Microcontroller directly. The conventional setup uses a frequency to voltage converter to find the speed whereas a new technique is used to calculate the speed from the IR sensor output without using frequency to voltage converter. The motor is controlled remotely with a ±5 rpm tolerance.

CONCLUSION:
Different speeds are maintained at the given set speed by varying the duty cycle of PWM using PIC16F877A MICROCONTROLLER and a wireless sensor ZIGBEE with a resolution of ±5 rpm tolerance .The measured speed values are transferred by serial interface to the PC and are logged into a text file and are visualized with the aid of XCTU front.
The radius of the location under observation can be increased by 150 meters using an Xbee-Pro instead of ordinary Xbee. Alternatively, using a mesh network with Xbee the distance between the host and sensor node is not a crucial parameter. The acquired data can be further analyzed or used for control of the remote process.

LEVEL CONTROL USING IMAGE RECOGNITION ( my R&D project)

2010-08-16T06:19:00.000-07:00

LEVEL CONTROL USING IMAGE RECOGNITION
bharadwaj874@gmail.com

Abstract--. The main aim of the work undertaken in this paper is to present a digital device for level control using image recognition. Integral to process control in many industries, different types of level measurement sensors used like ultrasonic, capacitance, hydrostatic pressure, electromechanical, gamma types. All these are of analog sensors rather than a digital. A simple webcam with roborealm software is used for sensing level and control. Matlab takes some time delay to track, recognize the live process & delay in generation of commands for control application so problem arises for live monitoring & control, whereas Roborealm software has an advantage that it recognizes & tracks live objects faster and generates commands for control applications. The position of Webcam is in horizontal for transparent tank or on top of tank for non-transparent. A microcontroller based controller circuit designed for tank level control. The use of object tracking with image recognition achieved greater accuracy & resolution is in the order of five times the capacitance type level sensor. The method developed shows the effectiveness of the scheme employed.

Keywords-- Roborealm, image recognition, RGB filter, COG module, calculate distance module.

LEVEL MONITORING SCREEN :

OPERATION:
The experimental setup consists of a webcam arrangement either on top of tank or in horizontal to tank that depends on transparency of tank. A green colored float is placed in the tank. RGB filter removes all surrounding colors except float. The convex hull module will transform a binary blob into its convex hull & it is used to simplify the shape of a binary blob by simplifying the perimeter of float, which reduces lighting effects of environment. The smooth hull module is used to be average blobs perimeter within the specified window. The final outline is then weighted against the new averaged outline and the original. Convex hull & smooth hull is used to reduce outside noise and achieved better tracking. The Mean filter is used to soften an image by averaging surrounding pixel values.

Center of Gravity (COG) module locks the float and calculates the co-ordinates of present float position. The initial co-ordinates of float saved in a variable, when the tank is empty and save current co-ordinates in another variable. Now the calculate distance module provides a way to easily calculate the distance from the two variables. The X co-ordinate is making null value in calculate distance module. Now we get the current level of tank in terms of distance. A VB script program is used to convert distance to level of tank. The set point of tank level stored in VB script. A simple if & else statements are used for control application. If current level less than set point then send a command via serial port to 8051 microcontroller to open the control valve using a 12v dc motor controlled by L293D motor driver else close the control valve when current level exceeds set point.

CONCLUSION:
The use of image recognition for level measurement and control achieved greater accuracy & resolution is in the order of five times the ordinary analog capacitance type level sensor.

The aim of this project is to provide the security for the private places by providing some security code to open the door. A small hardware model, which is as real as real world application, is built in this project. The user must give correct security code to open/close the door. The door will be opened whenever the authorized person enters the correct password, other wise the door will not open. It can further implemented to give a buzzer when a person enters the wrong code. In this project we are providing security for some areas and it gives some alarms when any person passes through that zone i.e Compound wall security. We also place the fire sensor in this project. if any fire occurs it will detect and give alarm to the security person.

Data acquisition system & logging system

2010-08-16T05:04:00.000-07:00

PROJECT TYPE

Microcontroller(AT89c51) hardware design with software development (Device Driver). PIC micro controller (AT89c51) based.

PROJECT DESCRIPTION

8 temperature sensors are connected (4 shown in diagram for simplicity).values of all the sensors are sent serially by uc to pc.

Software DAQ System takes these values and shows them on its front panel, and also log them to the data base daq.mdb. we can set some parameters like

Set point

Low limit

High limit

when temperature of some sensor increases beyond set point ....the heater connected to controller(specific for data sensor) will be turned off / and on in opposite case. And high limit and low limits are for alarm. when temperature goes above high limit or below low limit the alarm will be turned on.
