The invention discloses a signal lamp fault detection method and device. The method comprises the steps of: obtaining a current current value and a current voltage value of each lamp panel of a signallamp, and determining a lamp panel fault for any lamp panel when the current current value and/or the current voltage value of the lamp panel does not accord with a fault threshold of the lamp panel,wherein the fault threshold of the lamp panel is obtained by training and learning according to the voltage value and the current value of historical voltage regulation in a voltage regulation dot matrix of the lamp panel. The fault threshold of each lamp panel can be obtained by training and learning the voltage value and the current value generated during historical voltage regulation, so thatthe fault threshold has a self-learning function, and the detection accuracy is improved.
本发明公开了一种信号灯故障检测方法及装置,该方法包括获取信号灯的各灯盘的当前电流值和当前电压值,针对任一灯盘,在确定灯盘的当前电流值和/或当前电压值不符合灯盘的故障阈值时,确定灯盘故障。其中,该灯盘的故障阈值是根据灯盘的调压点阵中的历史调压的电压值和电流值训练学习得到的。由于可以通过对历史调压时产生的电压值和电流值进行训练学习来得到灯盘的故障阈值,可以使得故障阈值具有自学习的功能,提高了检测的准确率。
