Description

technical field [0001] The invention relates to the field of signal detection, in particular to an intelligent detection device for traffic signal lamp failure and a detection method thereof. Background technique [0002] With the current surge of urban traffic flow and the widespread use of traffic lights in cities, it is difficult to maintain them. Major companies in the industry are looking for suitable solutions to complete the huge dilemma of maintenance work after the implementation of signal control equipment. Existing processing technologies basically focus on single processing based on mutual induction mode and voltage division mode. The implementation effect is not ideal, and it is difficult to achieve an effective balance between false alarm rate and missed alarm rate. [0003] The fault detection system involved in the existing solutions only focuses on traffic signal lamp faults, while ignoring the associated system faults caused by abnormal handling of traffic ...

AI Technical Summary

Problems solved by technology

On the one hand, testing equipment and systems are vigorously adopted, and on the other hand, complaints from citizens, reprimands from supervisors, and heavy workloads of maintenance personnel cannot effectively solve the problem that traffic flow is seriously affected when signal lights fail

The current technical solution has the following problems: 1) Most of the traffic lights currently in use do not have a traffic light fault detection module; 2) Some traffic lights have been equipped with a signal light detection module but cannot be enabled due to high false alarm rate; 3) Independent design And the existing signal fault detection module installed with the voltage and current separate detection, resulting in a high rate of equipment false alarms and little effect can not be used normally; 4) The power failure in the area where the signal machine is located, and the signal machine equipment has no notification function; 5) Signal chassis There is no alarm function if the door is opened for no reason; 6) The abnormality of the signal light at the intersection of the solar signal light can only be known through inspection; 7) The location of the fault alarm is not clear and cannot be located in real time; 8) There is no function of linkage to geographic information, and the fault location information can only be entered manually Navigation, prone to going to non-fault points; the present invention solves such problems
