Operation method of electric energy meter based on multi-working mode

Abstract

The invention relates to an electric energy meter operation method based on multiple operating modes. According to the invention, at least a production operating mode and a delivery operating mode areset in advance for an electric energy meter, a production operating mode control word of the electric energy meter defaults to be allowance for entering the production operating mode, and the electric energy meter receives parameter setting for the electric energy meter after entering the production operating mode; a process of modifying the production operating mode control word is executed whenthe electric energy meter is requested to enter the production operating mode again, the production operating mode control word of the electric energy meter is set to be a forbidden state after the electric energy meter enters the delivery operating mode, the electric energy meter is forbidden from entering the production operating mode again, and the electric energy meter enters the delivery operating mode at the same time, so that the field operation safety of the electric energy meter is ensured, multiple times of data interaction and authentication between production software and the electric energy meter are avoided, the amount of data transmitted between the production software and the electric energy meter is reduced, and safety requirements of the field operation data are met. Meanwhile, the production complexity is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to an operating method for electric energy meters based on multiple working modes. Background technique [0002] In the current energy meter industry, the operation of existing energy meters mainly adopts the traditional operation method based on the DL / T 698.45 communication protocol. The traditional operation method of the energy meter is based on a single working mode, that is, for all the energy meters The parameter setting must adopt an encryption scheme, and the production software in the production stage also needs to use ciphertext or plaintext and data verification code when reading most of the parameters before it can successfully read the parameters of the energy meter. [0003] Specifically, the traditional operation method of the electric energy meter based on the DL / T 698.45 communication protocol includes the following four steps: the first step is to establish t...

Problems solved by technology

[0004] In the traditional operation method of the above-mentioned electric energy meter, due to the single working mode of the electric energy meter, it cannot take into account the data security requirements for parameter setting in production and field operation; in addition, the traditional operation method of the existing electric energy meter will increase the energy meter and production The number of data exchanges and the amount of data between software will bring a lot of inconvenience to the production of electric energy meters and affect production efficiency
