Wi-Fi (Wireless Fidelity)-based wireless meter reading device

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.
