and the data sending module is used for sending the IMU data and the identity ID to the base station.
The base station comprises a second detection module, a data receiving module and a data uploading module;
the second detection module is in data communication with the first detection module at fixed time intervals and is used for carrying out state detection on the electronic gear;
the data receiving module is used for receiving IMU data and identity ID sent by the electronic gear;

and the data interface is in butt joint with other systems and sends the obtained wheel gear loading and unloading time to other systems.
When the electronic wheel chock stops moving (is static), the first detection module enters a sleep mode under the prompt of the IMU module; when the electronic wheel chock moves, the first detection module wakes up under the prompt of the IMU module and enters a working mode.
After the first detection module enters the working mode, data communication is carried out between the first detection module and the second detection module at fixed time intervals, and the first detection module is used for carrying out state detection on the electronic gear.
