A brake pipe pressure monitoring system evaluates pressure flow in the brake pipe and alerts a train driver when the brake pipe flow indicates a brake system failure. The system has a brake pipe pressure module coupled to a computer-controlled brake and a brake pipe pressure transducer, a main reservoir pressure transducer, and a flow transducer that determine pressure flow from the main reservoir to the brake pipe. The brake pipe pressure module is programmed to calculate and track a flow rate in the brake pipe over time and determine whether the flow rate in the brake pipe over time exceeds a predetermined threshold. Under the condition that the flow exceeds a preset threshold value, a brake controlled by the computer sends out a signal to alarm a train driver about the fault condition.
制动管压力监测系统评估制动管中的压力流量,并且在制动管流量指示制动系统故障时向列车驾驶员报警。该系统具有制动管压力模块,其被耦接到计算机控制的制动器以及制动管压力换能器、主储存器压力换能器和流量换能器,其确定从主储存器到制动管的压力流量。制动管压力模块被编程为计算和跟踪制动管中随时间的流量,并且确定制动管中随时间的流量是否超过预定阈值。在流量超过预定阈值的情况下,计算机控制的制动器发出信号向列车驾驶员报警故障状况。
