VEHICLE MONITORING AND CONTROL SYSTEM USING MICROCONTROLLERS .doc (Paper Presentation)

ABSTRACT:

It is observed that most of the accidents occur due to the driver’s ignorance of traffic and safety rules. It is a practice for the drivers to drive the vehicle beyond permitted limits. Depending on the terrain, and other conditions, speed restrictions may be imposed on drivers from time to time. Therefore, a system monitoring the speed and other desired vehicle parameters can be installed in the vehicle to warn the driver appropriately and intervene to control if necessary.

One may not know the instantaneous position of a vehicle and it’s arrival time. Generally, the truck operators depend on intermittent telephone calls made by the drivers .To overcome such problems, an automatic monitoring system can be established with monitoring stations located at important major junctions, cities through which the vehicles ply. As the vehicle approaches a monitoring station, it has to automatically identify itself and upload critical data about the vehicle and operating conditions. The monitoring station can send modified control parameters and guidelines to the vehicle driver. For this purpose, we need a RF (radio frequency) transceiver system.

In general, vehicle monitoring, tracking and such activities are done using separate systems and they require some mechanical force as input. Speed is monitored using speedometer and for controlling mechanical force is required to decelerate it. Fuel level monitoring, proximity detection, battery monitoring, etc requires separate system. This paper presents a micro-controller-based control and monitoring system. Normally we need to use extra RF building blocks to provide RF link increasing the system complexity. In such cases, a PSOC (Programmable System-On-Chip) micro-controller can be used in place of conventional approach. In this system, initially a building block can be used to monitor the status of vehicle and store it in memory. Then, same building block will be configured as a receiver and
