Abstract
A brake pipe pressure monitoring system evaluates the flow of pressure in the brake pipe and alerts the train driver when the brake pipe flow indicates a brake system failure. The system has a brake pipe pressure module coupled to computer controlled brake as well as to a brake pipe pressure transducer, a main reservoir pressure transducer, and a flow transducer that determines the amount of pressure flow from the main reservoir to the brake pipe. The brake pipe pressure module is programmed to calculated and track the flow in the brake pipe over time and to determine whether the flow in the brake pipe over time exceeds a predetermined threshold. In the even that flow exceeds the predetermined threshold, the computer controlled brake is signaled to alert the train driver of the failure condition.
