The invention discloses a fault detection device for train equipment and a train, and relates to the field of fault detection.The fault detection device is provided with a controller, a processor, a plurality of first transformers and a plurality of AND logic circuits, and each equipment on the train corresponds to one transformer and one AND logic circuit; a controller, an AND logic circuit, a transformer, an AND logic circuit,..., a transformer and a processor are connected in series according to a certain sequence, the AND logic circuit performs logic and judgment based on a fault signal of equipment and an output signal of the previous AND logic circuit (or controller), and the fault signal is sent to the next AND logic circuit through the transformer; and the logic judgment and result of the last AND logic circuit is sent to the processor through the transformer, and the processor judges whether the equipment has faults or not based on the final logic and result, so that whether the equipment on the train has faults or not can be accurately found. In addition, a relay is replaced by the transformer, so that the size and the energy consumption of equipment are reduced, and the anti-interference capability is improved.
本发明公开了一种列车设备的故障检测装置及列车,涉及故障检测领域,通过设置控制器、处理器、多个第一变压器和多个与逻辑电路,列车上的每个设备对应有个一个变压器和与逻辑电路,按照一定顺序串联各个电路:控制器—与逻辑电路—变压器—与逻辑电路—.....—变压器—处理器,与逻辑电路基于设备的故障信号和上一个与逻辑电路(或控制器)的输出信号进行逻辑与判断,通过变压器发送到下一个与逻辑电路,最后一个与逻辑电路的逻辑判断与结果通过变压器发送给处理器,处理器基于最后的逻辑与结果判断这些设备是否存在故障,能准确发现列车上是否有设备发生故障。此外,将变压器替换继电器的方式,减小了设备体积和能耗,提高了抗干扰能力。
