Speed Monitoring And Controlling In Restricted Areas

Abstract

This project is developed for the users to monitor and control the Speed of the vehicle when it crosses restricted areas. The speed detection module consists of two IR transmitters and two receivers. One transmitter is connected first and a receiver is fixed just opposite to the transmitter. The other transmitter is connected at the same side but something away from the first transmitter. The second receiver is connected just opposite the second transmitter. When the vehicle passes the first transmitting and receiving unit, it senses that one vehicle is crossing. When it crosses the second unit, it also senses. The microcontroller unit calculates the speed=displacement/time taken. The speed is displayed in the LCD display. If the speed exceeds the particular level, the microcontroller controls the speed of the vehicle through RF modules. In the RF module, the RF transmitter section is connected at the restricted area. The RF receiver is connected with the vehicle. If the vehicle passes the area with high speed, the microcontroller operates the RF transmitter to transmit RF signal. The vehicle thus receives the signal and is given to the microcontroller through driver section. The microcontroller controls the speed of the vehicle. The vehicle motor is driven by DC power supply. Thus when the vehicle crosses the restricted area with high speed, the speed of the vehicle will be automatically decreased. This will prevent unnecessary accidents. The microcontroller program is written in assembly language. The microcontroller used is PIC16F877A.
