The invention relates to the field of traffic signal lamps, in particular to a self-diagnosis emergency risk-avoiding traffic signal lamp. The device is characterized by comprising three groups of normally-closed double-pole double-throw relays and a group of normally-closed relays, and starting from a green light signal line of an annunciator, the normally-closed relays are sequentially connected with contact switches of the relays and electromagnetic coils of the relays and then connected to a green light to form a loop; a yellow light signal line of the signal machine is sequentially connected with an electromagnetic coil of the relay and a contact switch of the relay and then is connected to the yellow light to form a loop; a contact switch of the relay, an electromagnetic coil of the relay and a contact light switch of the relay are sequentially connected from a red light signal line of the signal machine and then are connected to the red light to form a loop; in addition, a yellow flashing signal generator is arranged. The self-diagnosis emergency risk-avoiding traffic signal lamp has the beneficial effects that the self-diagnosis emergency risk-avoiding traffic signal lamp based on the signal lamp end is provided, and emergency risk avoiding can be guaranteed when a traffic signal lamp system breaks down.
本发明涉及交通信号灯领域,特别是一种自诊断应急避险交通信号灯。其特征是:包括三组常闭双刀双掷继电器,还包括一组常闭继电器,从信号机的绿灯信号线出发依次连接继电器的触点开关、继电器的电磁线圈后连接到绿灯形成回路;从信号机的黄灯信号线出发依次连接继电器的电磁线圈、继电器的触点开关后连接到黄灯形成回路;从信号机的红灯信号线出发依次连接继电器的触点开关、继电器的电磁线圈、继电器的触点灯开关后连接到红灯形成回路;此外,设置黄闪信号发生器。有益效果是:提供一种基于信号灯端本身的自诊断应急避险交通信号灯,在交通信号灯系统出现故障时能保障应急避险。
