Problems solved by technology

[0002] The stable operation of the power circuit is crucial to the normal operation of the entire system, but the operation of the power circuit will be affected by various factors such as ambient temperature and component life, resulting in the following problems in the maintenance and repair of the power circuit: 1) The power circuit The integrated chips and components interact with each other, and it is difficult to troubleshoot the cause of failure; 2) There are uncertain factors in the aging, service life and reliability of integrated chips and components
[0003] Although the application of fault pre-diagnosis and health management technology to electronic products has become an important development trend of domestic and foreign scientific and technological research and development in recent years, at present, the PHM technology of electronic products is far from mature and faces great challenges. Therefore, there is no The mature technology that can be used for reference can solve the problems existing in the power supply circuit

Abstract

The invention discloses an intelligent diagnosis system for a power supply and a protection method. Mainly, a failure of the power supply system is judged by the following two manners: 1) judging whether the power supply system works normally by using an infrared signal spectrum and a sound spectrum, 2) finding all the potential failure modes through a failure model and impact analysis based on apower supply circuit model, performing simulation operation under all the failure modes and obtaining simulation data so that the simulation data is more targeted and representative; and constructingthe power supply failure model in a manner of training a chaotic neural network through the simulation data. The power supply failure information obtained through the two manners not only contains thepower supply failure type but also contains an integrated chip or an electronic element, which breaks down in the power supply circuit, thereby greatly facilitating the subsequent inspection and maintenance of the worker, reducing the workload, and improving the working efficiency.
