The invention discloses a wireless traffic signal controller and a signal processing method thereof. A wireless signal is received through a first wireless communication channel; analyzing the received wireless signal, and judging whether the wireless signal accords with a preset communication protocol or not; if yes, continuing to communicate with the corresponding traffic signal lamp through the first wireless communication channel; and if not, outputting indication information for indicating that the same-frequency interference exists. The installation personnel and the maintenance personnel can directly determine the existence of the same-frequency interference through the indication information and debug the wireless traffic signal controller, and the installation personnel and the maintenance personnel do not need to avoid the interference through blind debugging, so that the debugging of the wireless traffic signal controller is more convenient, and the debugging efficiency of the wireless traffic signal controller is improved.

    一种无线交通信号机及其信号处理方法,通过第一无线通信信道接收无线信号;对接收到的无线信号进行解析,判断无线信号是否符合预设通信协议;若是,则继续通过第一无线通信信道与相应的交通信号灯进行通信;若否,则输出用于指示存在同频干扰的指示信息。由于安装人员和维护人员可以直接通过该指示信息确定存在同频干扰并对无线交通信号机进行调试,无需安装人员和维护人员通过盲调来规避干扰,这样使得无线交通信号机的调试更加方便,从而提高了无线交通信号机的调试效率。
