Large-consumer remote centralized meter reading interface device of power meter

The invention discloses a large-consumer remote centralized meter reading interface device of a power meter suitable for a region covered by a GSM/GPRS (Global System for Mobile Communication/General Packet Radio Service) or TD-SCDMA ((Time Division-Synchronization Code Division Multiple Access) network, effectively solving the problem of time and energy waste of a manual meter reading manner and an IC card charging manner. The large-consumer remote centralized meter reading interface device comprises a control part, a meter metering value receiving part and a wireless communication part, wherein the meter metering value receiving part and the wireless communication part are respectively connected with the control part through a UART (Universal Asynchronous Receiver Transmitter); and the meter metering value receiving part is in charge of reading data of a 485 interface meter and sending read data to the control part through the UART, the control part is used for computing and processing the data, and sending
