Hardware diagnosis system based on edge operation

The invention discloses a hardware diagnosis system based on edge operation. The system comprises a bottom information collection layer, the bottom information collection layer acquires single board working state information and chip working state information on an internal circuit board of the power instrument, and returns single board working state information data and chip working state information data to the operation edge layer through a bottom communication network for operation of a diagnosis algorithm; the operation edge layer receives the updated service data and prior data distributed by the cloud of the service distribution layer; through the edge computing architecture, the cloud pressure of the diagnosis system is reduced, Meanwhile, the computing power utilization rate of each idle instrument in the power instrument is increased. Meanwhile, through a cloud-edge structure, an algorithm and a database can be updated online in real time, and uninterrupted dynamic expansionand upgrading are achieve
