Abstract

The invention relates to a traffic radar working state self-detection method and system, and the method comprises the steps that an MCU processor obtains the working information of the front end of a radar and a node voltage signal outputted by a power module, carries out the centralized processing of the working information and the node voltage signal, and transmits the processed working information and node voltage signal to the power module; judging whether the working state of the radar is abnormal or not through the processed data; when the working state of the radar is judged to be abnormal, the MCU processor carries out fault warning through the state indicating lamp, feeds an abnormal result back to the central control platform through the communication module, and reports fault information. Through the method and the device, the problem of low troubleshooting efficiency when the working state of the radar system is detected is solved. Whether the radar system operates normally or not can be monitored in real time, fault reasons can be quickly found, fault points can be positioned, and the troubleshooting efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of radar monitoring systems, and in particular, to a method and system for self-detection of the working state of a traffic radar. Background technique [0002] With the intelligent development of urban traffic and the popularization of vehicle-road coordination of driverless vehicles, millimeter-wave radars are increasingly used in road monitoring due to their ability to accurately detect targets at long distances and wide viewing angles under all weather conditions. . In order to improve the real-time and stability of the radar's monitoring of the road, it is necessary to monitor and detect the working state of the radar to ensure the normal operation of the radar. [0003] In the related art, the radar transmitter signal is formed into a self-test signal through a coupler and fed into the radar receiving channel. Leak signal, realize self-check, calibration, sensitive automatic measurement and...
