Example Embodiment

[0020] The present invention will be further described below through specific embodiments.

[0021] The invention provides a remote infrared authentication system for an electric energy meter, which includes an electric energy meter and a mobile terminal, and also includes

[0022] The dedicated server is used to receive the uploaded infrared authentication request instruction, and send the instruction to the State Grid encryption machine and forward the returned infrared authentication instruction. The dedicated server and the State Grid Encryptor realize data communication through the local area network, and obtain the data required for infrared authentication from the State Grid Encryptor through the local area network and in accordance with the communication protocol of the State Grid Encryptor, including random numbers, dispersion factors, cipher texts, etc.

[0023] The mobile terminal communicates with a dedicated server via the Internet to send infrared authentication request...

Abstract

A long-distance infrared certification system for an electricity meter comprises a dedicated server, a mobile terminal, a USB infrared communication module and the electricity meter, wherein the USB infrared communication module comprises a USB interface, an infrared transmitter, an infrared receiver, a UART chip and a 38 KHz infrared carrier signal producing circuit; the 38 KHz infrared carrier signal producing circuit is connected with the infrared transmitter; the UART chip and the USB interface are connected for transformation between USB data and UART data; the infrared transmitter and the UART chip are connected, so that an infrared certification instruction after transformation is sent to the electricity meter; the infrared receiver receives a certification result returned by the electricity meter; the electricity meter receives the infrared certification instruction, determines whether certification succeeds and sends the certification result. Infrared certification and meter reading are realized by means of the mobile terminal, a large amount of read data can be stored and can be sent to the dedicated server in real time, and the system is flexible and convenient to use.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a remote infrared authentication system and method for electric energy meters. Background technique [0002] National standard "Q / GDW 1365-2013" 7.2.2 of the Ministry of Electric Power stipulates that: before using the infrared communication interface, infrared authentication operation should be performed, and the operation authority should be opened. This function can only be realized through the infrared communication interface; if the infrared authentication fails or the infrared authentication After failure, the energy meter should only support the reading number, communication address, record number, current date, current time, current electric energy, current remaining amount, and infrared authentication query commands, and other information is not allowed to be read out. At present, the handheld meter reading machine dedicated to the State Grid is used for infrared me...
