Abstract

The invention relates to a Wi-Fi (Wireless Fidelity)-based wireless meter reading device, comprising an embedded processor, a storage unit, a clock module, a downlink communication module, an uplink communication module and a power supply module; the clock module provides clock frequencies for the running of the embedded processor and is used for stamping a time stamp to the electric meter data; the downlink communication module is of a Modbus-RTU (Remote Terminal Unit) field bus communication manner, is connected with a plurality of intelligent electric meters to finish data interaction with the electric meter, and acquires the data of the plurality of the electric meters to the storage unit; the uplink communication module is of a Wi-Fi wireless communication manner, can automatically search and can be connected to a special Wi-Fi wireless network, and transmits the data of the electric meters, stored in a memory, to a management centre through the network. The meter reading device provided by the invention realizes simultaneous acquisition of the data of the plurality of downlink electric meters and has high speed and reliability for data transmission; and the meter reading time is greatly shortened and the efficiency and the instantaneity of the meter reading are promoted. Moreover, the meter reading device has the characteristics of simplicity for installation, convenience for networking, and low workload for maintenance.

Description

technical field [0001] The invention relates to a wireless meter reading device, in particular to a Wi-Fi-based wireless meter reading device. Using Wi-Fi wireless network to realize the automatic meter reading device for automatic meter reading and monitoring of digital electric meters with Modbus-RTU (Modbus serial link RTU mode) communication and data output functions. technical background [0002] With the development of the power network to "informatization, digitalization, automation, and interaction", the smart grid has emerged as the times require, and the pursuit of the smart grid is to monitor and collect electricity consumption information of the grid and customers in real time, and adopt the most economical and most Safe power transmission and distribution methods deliver power to end users to achieve optimal allocation and utilization of power. The drawbacks of the traditional manual meter reading system are becoming increasingly prominent, mainly in: heavy wor...
