Fabrication of automatic vehicle over speed controlling system for school zone
FABRICATION OF AUTOMATIC VEHICLE OVER SPEED
CONTROLLING SYSTEM FOR SCHOOL ZONE
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.
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 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

Low power consumption
Since it is automatic the programming is required to feed in the controller.
It can be used in schools zones, hospitals etc.
