The invention provides a signal lamp control system. In the signal lamp control system, a CCM is used for issuing a control instruction to each CTM, each CTM is used for forwarding the control instruction received by the CTM to all SLMs in communication connection with the CTM, and the working state of a signal lamp in each SLM is controlled by the control instruction received by the CTM. Therefore, the signal lamp control system can control the working state of the signal lamp. And the CCM is in communication connection with each CTM, and each CTM is in communication connection with at least one SLM, so that at most two communication cables are needed from the CCM to each SLM, four strong current cables are not needed any more, and the overall cost of the signal lamp control system is reduced.
本申请提供一种信号灯控制系统。在该信号灯控制系统中,由于CCM用于下发控制指令至每个CTM,每个CTM用于将自身接收到的控制指令转发至自身通信连接的全部SLM,每个SLM中信号灯的工作状态受控于自身接收到的控制指令,所以该信号灯控制系统可以实现对信号灯的工作状态的控制;又由于CCM与每个CTM通信连接,并且每个CTM与至少一个SLM通信连接,所以从CCM到每个SLM之间最多仅需要两根通信线缆,而不再需要四根强电线缆,因此该信号灯控制系统降低了自身的整体成本。
