Weak signal-based intelligent detection and diagnosis system for wiring of electric energy metering device before power transmission

The invention discloses a weak-signal-based intelligent wiring detection and diagnosis system for an electric energy metering device before power transmission, and the system comprises an on-site intelligent detection system which is used for connecting the electric energy metering device, inputting electric signals needed by various types of electric energy metering devices to the electric energy metering device, detecting and calculating wiring data through an electric signal fed back by the electric energy metering device; the wiring signal analysis module receives wiring data detected by the field intelligent detection system; judging a wiring error type result and an unidentified wiring error result; the communication module carries out data transmission with the wiring information analysis module and the intelligent diagnosis system. The intelligent diagnosis system is used for storing backup wiring data and discrimination results, analyzing detection data of unidentified wiring error results to obtain
