Description

Technical Field

[0001] The present invention relates to the technical field of electronic circuit fault identification, and in particular to an electronic circuit fault identification optimization system based on an intelligent algorithm. Background Art

[0002] Electronic circuits refer to circuits composed of electronic devices and related radio components. They include amplification, oscillation, rectification, detection, modulation, frequency conversion, waveform conversion, and various control circuits. They are widely used in various electronic devices. According to the different forms of processed signals, electronic circuits can usually be divided into two categories: analog circuits and digital circuits.

[0003] In analog circuits, each device, such as capacitors, resistors, inductors, and power switches, has the opportunity to experience performance and parameter degradation. Due to the different roles of various devices in analog circuits, various degradations have different effects on equipment operation. If the degradation status and degree of the circuit can be evaluated in a timely manner, the production unit can take timely measures, such as replacing components, starting spare equipment, increasing or reducing production plans, etc.

[0004] After searching, the Chinese patent application number 202411018131.2 discloses a method for fault detection of battery cells, including: step S1: collecting battery cell parameter data in the battery system of the tower base station and preprocessing, and using the generalized principal component analysis method to extract the battery cell state characteristic quantity according to the preprocessed battery cell parameter data; step S2: setting the DC internal resistance calculation cycle, the battery management system monitors the current time in real time. If the set DC internal resistance calculation cycle is reached, the battery cell detection process is automatically triggered, otherwise, continue to wait until the next cycle; step S3: after the detection process is started, the battery management system sends a charging instruction to the DC / DC module through the SCI interface, starts charging the battery, and monitors the battery charging status. If it is detected that the battery is full, the battery output voltage is adjusted to the current busbar voltage level, and a short-time discharge test is performed.

[0005] The battery cell fault detection method in the above patent has the following deficiencies: the system is only for battery cells and can detect the type of battery cell fault more conveniently; however, the analog circuit also includes capacitors, resistors, inductors, power switches and other devices. During actual use, various electronic devices in the analog circuit will age, and any failure of any electronic device will cause problems in the overall analog circuit. Therefore, it is necessary to perform fault detection and identification on the overall analog circuit to ensure the continued use of the overall circuit. Summary of the invention

When running the analysis, the intelligent analysis module calls the corresponding photoresistor data through the component data setting unit, and then performs fault analysis to improve the accuracy of fault analysis.
