Meter reading system for intelligent electric meter

Abstract

The invention relates to a meter reading system for an intelligent electric meter. The system comprises an intelligent electric meter part, a portable meter reading terminal and an information treatment platform, wherein a control module of the intelligent electric meter part is used for collecting electric quantity data and computing electric quantity charge information and the control module is used for storing the collected electric quantity data and the computed electric quantity charge information in a memory module; an RFID label has a readable unique identification code which is associated with electric meter information and user information, wherein the user information comprises a user telephone number; the portable meter reading terminal comprises a terminal control module, an information reading module, an input module, a display module, a USB module, a GPRS communication module and a memory module; and the information treatment platform comprises an information receiving unit and a short message information; the information receiving unit is used for receiving the electric meter information, the user information, the electric quantity data, the electric quantity charge information and the like from the portable meter reading terminal; short messages are sent to the user telephone number contained in the user information by virtue of the short message platform.

Description

technical field [0001] The invention relates to the field of electric power, and more specifically, the invention relates to an intelligent power meter reading system. Background technique [0002] With the vigorous development of the power industry and the comprehensive construction of the smart grid, as a key node connecting the grid and users, the role of the smart energy meter has become prominent, and it has become one of the basic equipment of the smart grid. As the terminal equipment of the smart grid, the basic function of the electric energy meter is the legal metering tool for the purchase and sale of electricity, and it also carries the task of collecting electricity information and data. With the support of modern communication technology, Internet technology and computer technology, the electric energy meter, which originally only relied on the connection of power lines, has been integrated into the information system of society. [0003] At present, the main m...

AI Technical Summary

Problems solved by technology

[0004] The timeliness of manual meter reading is poor, the workload of statistics is heavy, and the cost of meter reading is high

The RS485 bus meter reading method is relatively mature, but the RS485 bus meter reading method is relatively complicated in maintenance and construction, and the maintenance cost is high

The wireless meter reading method mainly utilizes the existing general packet radio service (General Packet Radio Service, referred to as: GPRS), the global system of mobile communication (Global System of Mobile communication, referred to as: GSM) or other third generation mobile communication technology (3rdGeneration, Abbreviation: 3G) network, the disadvantage of this method is that it needs to rely on the mobile network of the operator, so it needs to pay a high traffic fee to the mobile operator, so the operating cost is relatively high
