     2. The management center (master station) controls the device through GPRS and sends power purchase parameters, sets and inquires the prepaid electricity value, automatic meter reading information, prepaid control parameters, and collects power consumption, maximum demand, and electric energy indication values. , status and other information.

     3. The device is composed of main switch/transformer unit, special-purpose change collection terminal, multi-function meter, etc. The special-purpose change collection terminal has passed the test of the Electric Power Academy and can be connected with the electricity information system of the power company, and the communication protocol with the main station conforms to DL /T645--1997.
