Abstract

The present invention provides a device fault diagnosis method, device, storage medium and electronic device. The method includes: when the device is in the running state, detecting the radio frequency signal interaction frame sent by the read-write device in the device and the The transmission power value of the radio frequency signal; performing demodulation processing on the radio frequency signal to obtain a baseband signal corresponding to the radio frequency signal; acquiring feature information of the baseband signal, wherein the feature information is used to represent the baseband signal Signal characteristics; determine whether the device is in failure state. The present invention solves the problems in the related art that in the case of a device failure, offline fault analysis is required, resulting in high equipment maintenance costs, inability to quickly locate field device faults, and affecting user experience.

Description

technical field [0001] The invention relates to the field of intelligent traffic detection, in particular to a device fault diagnosis method, device, storage medium and electronic device. Background technique [0002] Among related technologies, with the formal promulgation of the national standard GB / T 35786, automotive electronic identification has been gradually rolled out across the country, and has been applied in many cities. The car electronic identification reader is generally installed on a crossbar about 6 meters above the ground, and the electronic tag is installed on the windshield of the car. The vehicle generally passes through the detection section at a relatively high speed. In this application scenario, if the device fails, The traditional maintenance method is to remove the reader device by closing the circuit, and perform fault analysis offline. Such an intrusive maintenance method is expensive, and because it is not detected in real time, it is difficult...
