The invention provides a device and method for monitoring the health status of an underwater robot through electromagnetic information. The device includes an information collection part for collecting electromagnetic field signals of electronic equipment; an information processing part for collecting electromagnetic field signals collected by the information collection part Perform preprocessing, and store or forward the preprocessed electromagnetic field signals to the information analysis part; the information analysis part is used to separate and extract features from the preprocessed electromagnetic field signals, establish health records of electronic equipment and formulate health indicators. The detection function of the device of the invention can not only realize the health monitoring of the entire electrical system of the underwater robot, but also provide useful help for the electromagnetic compatibility design and rectification of the underwater robot by the detection data. The device of the invention can accurately give the electromagnetic radiation intensity and distribution of various parts of the aircraft, and can be used as an auxiliary device for active degaussing in the magnetic stealth of a large underwater robot after applying a DC voltage to the coil.
Description
technical field [0001] The invention belongs to the technical field of fault diagnosis, prediction and electromagnetic compatibility, relates to analog signal and digital signal processing, pattern recognition, clustering and other artificial intelligence technologies, and is suitable for electromagnetic signal detection and processing under relatively independent conditions of space electromagnetic environments such as underwater robots , aiming to improve the reliability of the electrical system, the accuracy of fault prediction and other functions. Background technique [0002] The 21st century is the century of the ocean, and it is also a period of strategic opportunities for my country to build a powerful ocean country. As a sharp tool for future development and control of the ocean, underwater robots are ushering in rapid and vigorous development, and their trend is towards large-scale, integrated, and intelligent direction of development. Nowadays, there are many type...
