Interface device for concentrative mass-user electricity meter reader

The utility model discloses an interface device for a concentrative mass-user electricity meter reader, which is applicable to places covered by GSM (Global System for Mobile Communications)/GPRS (General Packet Radio Service) or TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) networks and aims at solving the problems that the manual meter reading manner and an IC (integrated circuit) card charging mode are time-saving and effort-saving. The device comprises a control component, an electricity meter variable data receiving component and a wireless communication component, wherein the electricity meter variable data receiving component and the wireless communication component are respectively connected with the control component by an UART (Universal Asynchronous Receiver/Transmitter); and the electricity meter variable data receiving component is used for reading data of an electricity meter with a 485 interface, sending the read data to the control component by the UART, and the contro
