Description

technical field

[0001] The invention belongs to the technical field of automatic control, in particular to an intelligent detection system and method for an abnormality of an automatic sensor. Background technique

[0002] With the continuous development of science and technology in today's society, the degree of automation development in our country is getting higher and higher, and the demand for timeliness and accuracy of equipment failures is getting higher and higher. In recent years, many equipment failure detection methods have emerged to solve this problem. In the control of automated logistics equipment, the sensor is the "eye" of the logic execution of the controller program and plays a vital role. Once the sensor is falsely triggered or fails, it will definitely affect the logical purpose of the relevant control program. How to quickly and timely diagnose the abnormality of the sensor becomes very important.

[0003] In the existing automated logistics industry, ...
