OCONTROLLER BASED AUTOMATION OF

SPEED GOVERNOR


AIM:




The main aim of this project
is to present a conceptual model of a microcontroller
based variable electronic speed governor that can be implemented to control the speed

of
any vehicle depending on the local speed limit.


PURPOSE:




The purpose of the project is to control the traffic problem presently observed in
cities
, where due to large population and inadequate infrastructure, road safety
enforcement and tra
ffic regulation is very difficult. The

circuit is cost effective, efficient
and easy to implement on already existing vehicles.

DESCRIPT
ION:



The objective of the paper is to present a conceptual model of a microcontroller
based variable electronic speed governor that can be implemented to control the speed of
any vehicle depending on the local speed limit. The circuit is cost e
ffective, efficient and
easy to implement on already existing vehicles. Every city, town or a village, can be
marked and divided into individual zones. The division depends upon the area under
which the business, residential, and industrial regions come un
der. The central business
district being a very busy traffic zone demands the least speed limit, with the residential
and industrial zones having lesser traffic densities, the speed limits will vary accordingly.


Consider a city or town can be

divided into physical zones which are classified
according to different speed ranges. A transmitter is placed at all exit and entry po
ints of
the interface of zone

that transmits a message signal at carrier frequency, indicating the
upper limit v
alue of
the zone
speed range into which the vehicle is entering at that
moment, to the receiver which gives the message as an input to a preprogrammed
MICROCONTROLLER embedded within the automobile which compares the speed of

the vehicle measured by a sensor at th

regulates the speed of the vehicle. The speed of the vehicle can be varied by varying the
“duty cycle” of the pulse input. The entire system is a low cost variable electronic speed
governor, small in size and eas
y to assemble onto an existing vehicle without disturbing
its present arrangement.
