touch screen based speed control of single phase induction motor

Abstract:
This paper gives a brief idea of touch screen technology and its interfacing with a controller to control the speed of single phase induction motor. Here touch screen technology and Programmable System on Chip (PSOC) micro-controller concept is utilized which is less space consumption and easy to design. The aim of this paper is to have remote sensing and speed control of an AC motor.

Introduction
In this study, remote control of an Induction motor has been implemented by using a standard DTMF mobile phone. To drive the motor a digitally controlled drive system has been designed. Then a tone decoder circuit and microcontroller have been added between output of a mobile phone and the drive system of the motor. This system is flexible to be controlled with both GSM and DTMF based phones. With the developed drive and control
system the overall control of the motor has been achieved. The system has been tested for different speed, position and direction conditions successfully. The experimental results verify that the DTMF controlled drive system is highly effective, reliable, proper and applicable to achieve remote control of the motor. This study gets novel and important point of view for DTMF based remote control applications addition to the control of motors.

CONCLUSION
To control the speed of an AC motor by wireless communication using DTMF decoder technique. The applications for DTMF signaling are tremendous. DTMF offers highly reliable, cost effective signaling solutions which require no development effort on the user’s part. This signaling technique has been applied to a multitude of control and data communications systems. Wireless Control from Remote places, Easy of operation by using any mobile possible to on/off motor. Man mistake has been reduced Speed of motor varies simple pressing remote mobile buttons. Display the status of current operation. Reduce maintenance. Fault detection is easy.
