The invention relates to a road traffic signal control machine and a non-stop method and device, and the method comprises the steps: a signal lamp drive board continuously receives a phase control instruction sent by a main control board, and carries out the control operation of a corresponding signal lamp based on the phase control instruction; continuously recording the phase control instructions to form a phase control instruction sequence comprising a release period, wherein the phase control instruction sequence of the release period comprises a phase control instruction sequence and timing corresponding to each phase control instruction; and when the signal lamp driving board receives the abnormal phase control instruction of the main control board, the corresponding signal lamp control action is executed according to the recorded phase control instruction sequence of the release period. When the main control board breaks down, the driving board can be turned on according to the recorded signal lamp control sequence of the release period without causing turn-off or yellow flashing of the intersection, other equipment does not need to be added, and the purpose that the whole machine is not shut down and the intersection is not turned off when the main control board needs to be replaced or maintained is achieved.
本申请涉及一种道路交通信号控制机、不停机方法及装置,该方法包括:信号灯驱动板连续接收主控板发送的相位控制指令,并基于相位控制指令执行相应的信号灯的控制动作;连续记录相位控制指令形成包括一个放行周期的相位控制指令序列,一个放行周期的相位控制指令序列包括相位控制指令序列及每个相位控制指令对应的计时;信号灯驱动板接收主控板的相位控制指令异常时,按照记录的一个放行周期的相位控制指令序列,执行相应的控制信号灯的动作。本申请在主控板出现故障时,可以让驱动板按照记录的一放行周期的信号灯控制次序进行点亮,而不会引起路口熄灯或黄闪,无需增加其他设备,实现需要对主控板进行更换或维护时,整机不停机、路口不熄灯。
