FABRICATION OF AUTOMATIC VEHICLE OVER SPEED
CONTROLLING SYSTEM FOR SCHOOL ZONE
SYNOPSIS
The Objective of this project is to detect the speed of the vehicle and
cutoff the fuel if it exceeds the speed limit. This project is also used to avoid
accidents because of over speed. The concept has a motor to operate the
valve.

2. WORKING PRINCIPLE
This project is designed with control unit, Proximity Sensor, Stepper
motor and driver circuit with Relay and keypad. In this project we are using
Proximity sensor as a speed detector. A Proximity sensor can detect metal
objects. A proximity sensor often emits an electromagnetic field or beam
and look for changes in the field. The object being sensed is often referred to
as the proximity sensor's target. The proximity sensor is fixed near the valve
plate of the throttle valve, to find whether the valve is in open state or
closed. According to the opening of the throttle valve the speed of the
vehicle can be varied. Here we update the speed by each second and
compare with the fixed speed limit. The limited speed can changeable
3. through given keypad. If the current speed exceeds the fixed speed first time
then it intimate in LCD by crossing speed limit. Even after the warning if it
exceeds the limit again then it cuts the fuel to engine through relay
connected with solenoid.
ADVANTAGES
Low cost
Easy implementation
Low power consumption
More efficient
DISADVANTAGE
Since it is automatic the programming is required to feed in the
controller.
APPLICATION
It can be used in schools zones, hospitals etc.
