Patent attributes
A system comprises an equipment service vehicle and an off-board computer system. The equipment service vehicle further includes a power source, a power transmission link, a plurality of input devices, a plurality of output devices, and an on-board computer system. The on-board computer system further includes a plurality of microprocessor-based interface modules and a communication network. The plurality of interface modules are coupled to the power source by way of the power transmission link and are interconnected to each other by way of the communication network. Each of the plurality of interface modules is coupled to respective ones of the plurality of input devices and the plurality of output devices by way of respective dedicated communication links. The on-board computer system stores I/O status information for the plurality of input devices and the plurality of output devices. The on-board computer system transmits at least some of the I/O status information by way of a wireless radio-frequency communication link to the off-board computer system.
