The invention discloses a signal lamp failure detection method and device. The method includes obtaining the current current value and current voltage value of each lamp panel of the signal lamp, and determining the current current value and / or current voltage value of the lamp panel for any lamp panel. When the value does not meet the fault threshold of the lamp panel, it is determined that the lamp panel is faulty. Wherein, the fault threshold of the lamp panel is obtained through training and learning based on the voltage value and current value of historical voltage regulation in the voltage regulation lattice of the lamp panel. Since the fault threshold value of the lamp panel can be obtained by training and learning the voltage value and current value generated during historical voltage regulation, the fault threshold value can have a self-learning function, which improves the accuracy of detection.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of transportation, and in particular to a signal lamp failure detection method and device. Background technique [0002] When performing signal control at intersections, the fault detection function of signal lights is an important function of signal control. The accuracy of signal lamp failure detection is directly related to the safety and stability of intersection signal control. There are currently two detection methods, one is to set the detection module at the signal lamp end, and use current or light characteristics for detection. This detection method has high accuracy, but poor flexibility and implementation. It requires the traffic police to designate a specific manufacturer of signal lights, and to Replacement of signal lights already in use on the road. The other is to perform detection at the signal terminal, which has a low accuracy rate but good implementability. ...
