An intelligent electric energy meter adopting 2.4 G radio communication in place of infrared communication

Abstract

An intelligent electric energy meter adopting 2.4 G radio communication in place of infrared communication is disclosed and relates to the technical field of intelligent electric energy meters. The intelligent electric energy meter includes a microprocessor, and includes an electric energy metering chip, a liquid crystal driving and display module, a power supply module, a backup battery module, a daily-timing circuit module, a memorizer module, an electric energy pulse output module, a button inputting module, an RS485 communication module, a radio communication module and an ESAM security certificating module which are connected to the microprocessor. The electric energy metering chip is connected to a voltage collecting module, a current collecting module and a zero-line current sampling module, and is connected to the electric energy pulse output module. The radio communication module is a 2.4G radio module. The intelligent electric energy meter adopts the 2.4G radio module through which a manager can read data of the electric energy meter in a remote, rapid and large-scale manner, thus facilitating management of electric energy utilization information.

Description

technical field [0001] The invention relates to the technical field of smart electric meters, in particular to a smart electric energy meter which uses 2.4G wireless communication instead of infrared communication. Background technique [0002] With the development of wireless technology, there are more and more long-distance communication applications, which brings convenience to the information reading of smart meters. Traditional smart energy meters have infrared communication modules, and devices with infrared functions are used to read. Reading energy meter information, this method is slow (only K-level baud rate), short distance (only meter level), can only be transmitted in a straight line, can only be transmitted one-to-one, and is susceptible to light interference. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a smart energy meter that uses 2.4G wireless communication instead of infrared communication,...
