ABSTRACT:
There is provided a vehicle tracking and monitoring system for monitoring railway cars within a defined radius of a receiver for wireless communication. The system comprises a transmitter on-board each railway car, a receiver at a wayside station, and a central database at a remote location. The transmitter includes an RF circuit, an I/O circuit and a microcontroller for autonomously and spontaneously transmitting vehicle signals on a cyclic basis to the receiver. The transmitter periodically transmits railway car information and/or cargo status information to the receiver within a predetermined time interval, for example, every 15 minutes. In addition, the transmitted information is communicated from the wayside station to the central database over a longer time interval, fore example, every 24 hours. Accordingly, the central database develops a record of transit vehicle information based on the transmitted information for each transit vehicle in the defined radius of the receiver.
