The invention provides a signal lamp countdown timer fault monitoring method and device, wherein the signal lamp countdown timer fault monitoring method comprises the specific steps: step 1, collecting the voltage and power value of a countdown timer when the countdown timer is turned on, and learning the collected data to obtain a learning template; and step 2, acquiring power value data for measuring the lighting period of the countdown timer in real time, tailoring the power value data in the learning template according to mantissa alignment, comparing peak-to-peak values of the two groups of power value data, and after tailoring, if the power value data peak-to-peak value of the countdown timer acquired in real time is smaller than the preset proportion of the power value data peak-to-peak value in the learning template, judging that the countdown timer fails. According to the invention, the countdown timer can be monitored and the fault state can be accurately reported through small change of the intersection with a traffic signal lamp, and the method is reliable and economic.

    本发明提供了一种信号灯倒计时器故障监测方法及装置,其中一种信号灯倒计时器故障监测方法的具体步骤包括:步骤一,采集倒计时器亮灯时的电压和功率值,对采集到的数据进行学习获得学习模板;步骤二,获取实时测量倒计时器亮灯周期的功率值数据,与学习模板中的功率值数据进行按尾数对齐的裁剪,再比对两组功率值数据的峰峰值,裁剪后,若实时获取的倒计时器的功率值数据峰峰值小于学习模板中功率值数据峰峰值的预设比例,则判断倒计时器故障。本发明对在有交通信号灯的路口,经过较小改动,能实现倒计时器的监测,准确上报故障状态,且可靠经济。
