Cellular Phone Through Industrial AC/ DC Motor Speed Controlling System

Abstract

This project is developed to monitor and control the speed of an AC/DC motor through Telephone. It consists of a Microcontroller unit, LCD Display, Telephone tone converting module, Motor etc. The speed sensing unit senses the speed of the AC/DC motor. The sensor sends signal to the microcontroller. The microcontroller performs the speed calculation accordingly with the speed of the motor. The speed is displayed in a LCD display. The microcontroller also controls the telephone circuit. The department can track the unit value through telephone. When the administrator calls, the microcontroller unit attends the call and waits for particular code. The microcontroller sends corresponding data through the telephone line. It receives the signal and sends to the microcontroller through DTMF decoder. The data is displayed in a PC. The administrator can control the speed of the motor through telephone line. The Microcontroller programs are written in assembly language.
