Triac based Speed Control of an AC Motor using dtmf technique Presented by: BHARATH.N.T.(1RV14EE012) For more about project check out: http://yobuilder.com/ASxx
CONTENTS: Introduction Block diagram DTMF decoder Control and power circuit. Advantages and disadvantages. Conclusion.
Introduction: In this topic, remote control of an AC motor has been implemented by using a standard DTMF mobile phone and Triac. 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. The system has been tested for different speed, position and direction conditions.
BLOCK DIAGRAM:
HT9170 DECODER: FEATURES Operating voltage-2.5~5.5V 18 pin DIP package Low standby current Minimal external component 3.58MHz crystal or ceramic resonator No external filter is required.
DTMF Dual Tone Multi Frequency is the signal generated when you press an ordinary telephone's touch keys.
DUAL TONE FREQUENCIES FOR CORRESPNDING KEYS:
If press 1 then motor will TURN ON with Low speed. If press 2then motor will TURN ON with MID speed. If press 3then motor will TURN ON with HIGH speed. If press 5then motor will TURN OFF Motor. Mobile button 1 - Data Out from 0001h Mobile button 2 - Data Out from 0010h Mobile button 3 - Data Out from 0011h Mobile button 5 - Data Out from 0101h
Power circuit:
ADVANTAGES: Wireless Control from Remote places. Ease of operation By using any mobile possible to on/off motor. Speed of motor varies simple pressing remote mobile buttons. Display the status of current operation. The experimental results verify that the DTMF controlled drive system is highly effective, reliable, proper and applicable to achieve remote control of the motor.
DISADVANTAGES: If receiver mobile range not available then does not possible to communication between them.
