The invention discloses an annunciator red light control system under interlocking application. The system comprises an A-series signal lamp control unit, a B-series signal lamp control unit and a switching unit. The switching unit is used for controlling the A-system signal lamp control unit and the B-system signal lamp control unit to realize the main/standby switching, and each of the A-systemsignal lamp control unit and the B-system signal lamp control unit comprises a red lamp driving board used for the output control of red lamp signals; a signal lamp driving board which is used for theoutput control of signals of other color lamps except the red lamp; a safety control board which is used for sending a red light lighting control signal to the red light driving board; and a safety power supply board which cuts off the output of the safety power supply when the system fails. According to the technical scheme, it is guaranteed that the red lamp is normally turned on in the systemstarting process and the system fault, the red lamp and other color lamps have the combinatorial logic relation, and it is guaranteed that the red lamp is always kept in the turned-on state as long asthe system is powered on and the other color lamps are not turned on, so that the system safety is improved.

    本发明公开了一种联锁应用下的信号机红灯控制系统,包括A系信号灯控制单元、B系信号灯控制单元以及切换单元,所述切换单元用于控制A系信号灯控制单元、B系信号灯控制单元实现主备切换,所述A系信号灯控制单元和B系信号灯控制单元均包括:红灯驱动板,用于红灯信号的输出控制;信号灯驱动板,用于红灯以外的其他色灯信号的输出控制;安全控制板,向红灯驱动板下发红灯点灯控制信号;安全电源板,当系统故障时,安全电源板切断安全电源输出。本发明采用的技术方案,系统启动过程中和系统故障故障中均保证红灯正常点亮,且红灯与其他色灯存在组合逻辑关系,保证只要系统有供电,其他色灯未点亮的情况下,红灯始终保持在点亮的状态,提升了系统安全性。
