Abstract
An intra-vehicle communications system in a mining vehicle monitoring system. A status sensor, status radio transmitter and power source are located adjacent to a portion or component of the vehicle to be monitored and a status radio receiver is located adjacent to a vehicle-to-base transmitter that receives a status radio signal from the status radio transmitter and forwards that signal to a base station at a central monitoring location. Preferably a plurality of such sensors, status radio transmitters and respective power sources are distributed throughout the vehicle. The status radio transmitters are relatively low power devices which require relatively low power for operation. Preferably the vehicle-to-base radio operates at a different frequency from the intra-vehicle status radios so as to avoid mutual interference. In many cases the power sources obtain their power from the motion of the vehicle itself.
