OVER SPEED INDICATOR AND FUEL CUTOFF SYSTEM

ABSTARCT :

The Objective of this project is to detect the speed of the vehicle and cutoff the fuel if it exceeds the set speed. This project is very useful to the traffic police department in order to measure the speed of the vehicles. This project is also used to avoid the accident. This project is designed with control unit, speed sensor as speed sensor and driver circuit with Relay and keypad. In this project we are using speed sensor as a speed detector. A speed sensor can detect objects without any physical contact. The object being sensed is often referred to as the speed sensor's target. Here is an inductive speed sensor, requires a metal target. The speed sensor is fixed near the wheel of the vehicle for easy detection of sensor we fix a plate on the wheel. When vehicle is traveling on the road speed sensor crosses the plates and it gives the signal to control unit. The control unit is already programmed. Here we update the speed each second and compare with the fixed speed. The fixed speed can be changed through the given keypad. If the current speed exceeds the fixed speed first time then it intimates in LCD as OVER SPEED. Even after the warning if it exceeds the limit again, then it cuts the fuel to engine through relay connected with solenoid. When the speed limit is exceeded an alarm is kept to indicate the over speed.
