Method for detecting and wirelessly polling power cable intermediate joint

The invention discloses a method for detecting and wirelessly polling a power cable intermediate joint, and relates to the technical field of power cable intermediate joint detection. According to the method, a handhold terminal, a detection device and a power source module for powering the detection device are arranged. The handhold terminal comprises an MCU which is connected with a display and input module, a storage module I and a wireless communication module I. The storage module I is connected with an external interface module, and the detection device comprises a data processing unit which is connected with a current measuring module, a wireless communication module II, a temperature measuring module, a storage module II and a sound-light alarm module. The handhold terminal receives data sent by the detection module through the wireless communication module I, the data are stored in the storage module I after being processed by the MCU, and historical data stored in the storage module I are read by th
