According to the braking interface, the braking system and the braking method suitable for the heavy-load freight train, a front contact of a relay is connected to a dry contact of the locomotive braking system in parallel, after a main control computer breaks down or loses external power, the relay loses power, the front contact is disconnected, and then the dry contact is disconnected; and the unexpected emergency braking command cannot be output to the train, so that the potential safety hazard that the main control computer outputs the unexpected emergency braking command to the normally running heavy-load freight train due to failure or loss of external power is solved. Meanwhile, a sound-light alarm device is additionally arranged, and the lowest equipment list of the main control computer is automatically checked before the train is put into operation, so that the automatic protection function of the train is ensured to still conform to the fault-safety principle specified by the TB/T 2615-2018 railway signal fault-safety principle.
一种适用于重载货运列车的制动接口、制动系统和制动方法,将继电器的前接点并联在机车制动系统的干接点上,在主控计算机发生故障或失去外部电力后,继电器失电导致前接点断开,干接点随之断开,不会向列车输出非预期的紧急制动命令,解决了主控计算机因故障或失去外部电力而导致向正常运行的重载货运列车输出非预期的紧急制动命令的安全隐患。同时,通过增设声光报警装置以及在投入运行前对主控计算机进行最低设备清单进行自动检查,确保列车自动防护功能仍然符合《TB/T 2615‑2018铁路信号故障‑安全原则》所规定的故障‑安全原则。
