MICROCONTROLLER BASED AUTOMATION OF VARIABLE ELECTRONIC SPEED GOVERNOR
[attachment=21820]
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 traffic regulation is very difficult. The circuit is cost effective, efficient and easy to implement on already existing vehicles.
DESCRIPTION:
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 effective, 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 under. 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 points of the interface of any two zones that transmits a message signal at carrier frequency, indicating the upper limit value of the zones’ 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 the maximum allowable speed and automatically 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 easy to assemble onto an existing vehicle without disturbing its present arrangement.
SOFTWARE USED:
1. Embedded C
2. Keil IDE
3. Uc-Flash or ISP
4. Express PCB
HARDWARES:
1. Micro controller(LPC2148)
2. Power supply
3. RF Module (Tx & Rx)
4. IR Module (Tx & Rx)
5. LCD
6. Motor
