Abstract
The present invention is a system for monitoring and displaying a measured parameter in each of a series of similar modules. In one embodiment, the invention can be used to monitor a parameter or condition, such as the amount of fuel in a tank, in each of a plurality of coupled locomotives. The parameter is measured by an analog or digital sensor, the output of which is connected to a microprocessor. Each locomotive in the train has such a microprocessor, and each microprocessor is programmed in substantially the same way. The microprocessors in the several locomotives are programmed to communicate with each other, and to determine which one is in the lead locomotive, and what signals are being received from which microprocessor. The value of the measured parameters for any of the locomotives of the train can therefore be displayed by the microprocessor in the lead locomotive. The programming of the microprocessors is such that the system will work regardless of the arrangement of the locomotives.
