The invention provides a control circuit, method and system of a rail transit full-automatic unmanned signal machine. The circuit comprises a safety relay, a switch, a resistor and a current sensor. The switch comprises a lamp position control solid-state relay and a lamp-off state solid-state relay; a light-off state solid-state relay is connected in series with a resistor and then is connected in parallel with a light position control solid-state relay to form a control sub-loop; the output end of each control sub-loop is connected with a current sensor and then is connected with a signal lamp position to form a signal lamp loop; the safety relay is connected with the processor and controls connection or disconnection of the signal lamp loop through the control switch. The method can be suitable for rail traffic signal machine control in a light-on mode during manned driving and a light-off mode during unmanned driving, signal machine faults and board card faults are detected and alarms are sent in the modes of current detection, internal relay self-inspection, light-off mode loop self-inspection and the like, and it is guaranteed that safety control of a signal system is achieved.

    本发明提供一种轨道交通全自动无人驾驶信号机的控制电路、方法及系统,电路包括安全继电器、开关、电阻、电流传感器;开关包括灯位控制固态继电器和灭灯状态固态继电器;一个灭灯状态固态继电器与一个电阻串联后,再与一个灯位控制固态继电器并联形成一个控制子回路;每个控制子回路的输出端连接一个电流传感器后,连接一个信号灯位,形成一个信号灯回路;安全继电器连接处理器,通过控制开关以控制信号灯回路的导通或断开。本发明可适用于有人驾驶时的亮灯模式和无人驾驶时的灭灯模式下的轨道交通信号机控制,通过电流检测、内部继电器自检、灭灯模式回路自检等方式,对信号机故障、板卡故障完成检测并发送报警,保证信号系统的安全控制实现。
