ors 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,..................[:=> Show Contents <=:]
