Abstract

The invention relates to a fault detection device and a detection method thereof for a traffic crossing vehicle detector. Compared with the device in the prior art, the device solves the defect that the vehicle detector cannot carry out self-fault judgment. The fault detection device comprises a plurality of vehicle detection modules, a vehicle detector receiving module and a traffic signal control machine. the data output ends of the vehicle detection modules are connected with the data input end of the vehicle detector receiving module; and the data output end of the vehicle detector receiving module is connected with the data input end of the traffic signal control machine. Each vehicle detection module comprises a device detection sensor and a detection main control unit, wherein the control end of the device detection sensor is connected with the detection main control unit. According to the fault detection device and method, fault of the vehicle detector can be reported actively, and a control scheme of a traffic signal control system can be adjusted in real time according to fault condition.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a fault detection device for a traffic crossing vehicle detector and a detection method thereof. Background technique [0002] The vehicle detector is used to detect the traffic flow at the intersection. It is installed in each lane of the intersection. The induction control method in the signal control system controls the release of traffic lights completely through the traffic flow uploaded by the detector, and vehicle detection in terms of vehicle violation records, etc. The device also plays a vital role. At present, the detectors on the market do not have the function of actively reporting their own failures. Once the detector fails, the traffic signal control system cannot be degraded in time, which will have a great impact on the traffic at the intersection. With the development of urban intelligence, the induction control method in the traffic signal con...
