Abstract
A brake valve diagnostic and reporting system for a pneumatic only brake valve on a rail car which includes a brake pipe transducer for measuring brake pipe pressure; and a brake cylinder transducer for measuring brake cylinder pressure. A processor receives measurements from the transducers, compares the measurements against stored brake performance profiles, determines brake status from the comparison and prepares an event report for preselected brake statuses. A wireless transmitter connected to the processor transmits the report. An energy storage device powers the processor and transmitter.
