The invention relates to a road traffic signal lamp control conversion device, and belongs to a road traffic signal lamp control technology. At present, a mainstream road traffic signal lamp system mainly comprises a traffic signal controller (signal machine), and left turn signal lamps, straight signal lamps and right turn signal lamps in all directions. The signal machine and the signal lamps are connected in a one-lamp one-wire manner; when the signal machine outputs alternating current 220V on a certain connecting wire, the corresponding signal lamp is turned on; and when the signal machine is powered off, the signal lamp system stops running. The system is provided with a satellite time service module, can achieve precise time synchronization, and is used for memorizing the signal lamp phase time and period sent by the signal machine. Phase data exchange and phase control can be carried out through the communication bus and the signal lamp with the communication bus, and when the signal machine is powered off or breaks down, the signal lamp is continuously controlled according to the phase time sequence of the signal machine through the memorized phase time and period of the signal lamp by means of satellite time service.
本发明是一种道路交通信号灯控制转换装置,属道路交通信号灯控制技术。目前主流的道路交通信号灯系统主要由交通信号控制机(信号机)、各方向的左转信号灯、直行信号灯、右转信号灯组成。信号机与信号灯之间通过一灯一线连接,当信号机在某连接线上输出交流220伏时,对应的信号灯亮。当信号机停电时,信号灯系统停止运行。本发明带有卫星授时模块,可实现精准时间同步,用于记忆信号机发来的信号灯相位时间和周期。本发明可通过通信总线与带有通信总线的信号灯进行相位数据交换和相位控制,当信号机停电或故障时,本发明通过记忆的信号灯相位时间和周期,依托卫星授时,继续按照信号机的相位时序对信号灯进行控制。
