A traffic signal light abnormal state processing and return method and traffic signal light

Abstract

The invention discloses a traffic signal lamp abnormal state processing and returning method, and a traffic signal lamp. The traffic signal lamp abnormal state processing and returning method comprises the steps that a main controller acquires voltage values of lamp lines and current values of lamp holders of the signal lamp, processes an abnormal state when determining that the signal lamp is inthe abnormal state according to the voltage values of the lamp lines and the current values of the lamp holders of the signal lamp, and sends a pulse signal corresponding to the abnormal state to a relay control end. According to the traffic signal lamp abnormal state processing and returning method, whether the abnormal states that red light and green light are turned on simultaneously, the signal lamp is off and the like occur is judged according to the voltage values of the lamp lines and the current values of the lamp holders of the signal lamp, most of the abnormal situations that the redlight and green light of the signal lamp are turned on simultaneously due to electric leakage occurs on an output channel or a lamp control line of a traffic signal machine can be avoided, and the lamp color output reliability and maintainability of the signal lamp are greatly improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of traffic signal control, and in particular to a method for processing and returning an abnormal state of a traffic signal light and a traffic signal light. Background technique [0002] In the traffic signal control system, the stability and reliability of the signal lights are very important. Once the green lights of the conflicting directions are lit at the same time (green conflict), or the red and green lights of the same signal light are lit at the same time, it is easy to lead to a traffic accident. traffic accident. Therefore, the traffic industry attaches great importance to the abnormal detection of signal lights, and there are many types of detection methods. [0003] Most of the signal lights in the current signal control system are strong electric control signal lights. This type of signal light is prone to abnormal lighting due to electric leakage, abnormal output of...

Problems solved by technology

[0003] Most of the signal lights in the current signal control system are strong electric control signal lights. This type of signal light is prone to abnormal lighting due to electric leakage, abnormal output of the signal machine, etc., and finally causes red-green conflicts at intersections, red and green lights at the same time And other issues
