Fault Diagnosis System of DC Power Supply Based on Remote Wireless Communication
Abstract:Aiming at the existence of many fault data information during the operation of DC power supply, an improved ant colony neural network fault diagnosis system for DC power supply is designed including data layer, communication layer and network layer. ability. And realize the high-precision current sampling in the DC current source through the AC transformer. The hardware system mainly includes the input setting module, the power amplifier module, the output transformer, the sampling transformer and the rectifier module, etc., which are extracted and processed by the error calculation method. The fault diagnosis data in the power supply is newly extracted and monitored. The optimal diagnosis of DC power failure data information is realized by constructing ant colony algorithm. Through experiments, this research method has low fault detection error and strong search ability.
