The invention discloses a traffic signal lamp trigger type countdown control output method. The method comprises the following steps of S100, configuring a signal lamp fixed-range countdown duration and configuring current period phase information; s200, reading the periodic phase information of the traffic signal lamp at the current time node and the fixed-range countdown duration of the signal lamp, and generating an operation phase linked list; s300, judging whether the current phase losing the passing right and the time before the non-passing light color meet the configured fixed-range countdown duration or not; s400, if the set-range countdown duration is satisfied, triggering a corresponding countdown timer; if the set-range countdown duration is not met, countdown correction is carried out, and countdown extension time is calculated; and S500, the steps S200 to S400 are repeated. According to the invention, under the condition that traffic intersection parameters are configured in advance, the operation phase linked list is generated, the time of triggering the countdown timer by the trigger signal is accurately controlled by adding, updating and calculating the signal control data in advance, and a trigger type pulse control countdown algorithm is realized.

    本发明公开了一种交通信号灯触发式倒计时控制输出方法,包括以下步骤:S100、配置信号灯定程倒计时时长及配置当前周期相位信息;S200、读取当前时间节点的交通信号灯的周期相位信息及信号灯定程倒计时时长,生成运行相位链表;S300、判断当前失去通行权的相位,非通行灯色前的时间是否满足配置定程倒计时时长;S400、若满足配置定程倒计时时长则触发对应倒计时器;若不满足配置定程倒计时时长,则进行倒计时校正,计算倒计时延长时间;S500、重复步骤S200‑S400。本发明可在预先配置交通路口参数的情况下,生成运行相位链表,采用预先添加、实时更新、计算信号控制数据以达到精准控制触发信号触发倒计时器的时间,实现触发式脉冲控制倒计时算法。
