The invention discloses a dual-system degradation switching method for locomotive signal equipment, solves the problem that in the application process of the locomotive signal equipment, when the level of a decoding result of a standby system is lower than that of a decoding result of a working system, conversion between the working system and the standby system is not carried out, and belongs to the field of the locomotive signal equipment. The system A and the system B compare the decoding result of the system with the decoding result of the other system to determine whether the decoding result of the system is in the same or degraded state, and if not, 1 is added to the counting period of degradation switching. When the counting period of the degradation switching is greater than the threshold period, closing the dynamic output power supply of the system; when the dynamic output power supply of the working system is turned off and the dynamic output power supply of the standby system is turned on, the connecting plate switches the standby system and the working system through the switching circuit, and the locomotive signal equipment outputs a safe side, so that the driving safety is guaranteed.
机车信号设备双系统降级切换方法,解决了机车信号设备在运用过程中,当备用系统的译码结果比工作系统的译码结果级别低时,不进行工作系统与备用系统转换的问题,属于机车信号设备领域。本发明A系统和B系统对本系统译码结果与另一系统译码结果进行对比,确定本系统译码结果是否处于相同或降级状态,若否,降级切换的计数周期加1。当降级切换的计数周期大于阈值周期,关闭本系统的动态输出电源;当工作系统的动态输出电源关闭,且备用系统的动态输出电源开启,则连接板通过切换电路将备用系统和工作系统互相切换,机车信号设备输出安全侧,保障了行车安全。
