Remote asset monitoring system
First Claim
1. A vehicle monitoring system for monitoring a plurality of transit vehicles located within a defined area comprising:
- a transmitter on each of the plurality of transit vehicles for transmitting a plurality of vehicle signals, representing the status of vehicle and cargo, from each transit vehicle, said transmitter including means for generating said plurality of vehicle signals and autonomous means, which is operative absent any receiver on the vehicle, for spontaneously transmitting said plurality of vehicle signals on a cyclic basis over an extended time period;
at least one receiver located within the defined area for receiving at least one vehicle signal from each transit vehicle, said at least one receiver including means for determining vehicle data for each transit vehicle based on said at least one vehicle signal and means for storing said vehicle data for said plurality of transit vehicles to form a group of vehicle data; and
means for processing said group of vehicle data and developing a record of transit vehicle information for each transit vehicle in the defined area.

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.
