A method for shortening the factory parameter setting time of electric energy meter

Abstract

The invention relates to a method for shortening the setting time of factory parameters of an electric energy meter. The method includes the steps of sending, by production software, a command to initialize factory parameters of an electric energy meter to the electric energy meter, and initializes the factory parameters of the electric energy meter; making a judgment for an initializing processing result of the electric energy meter to know whether the factory parameters of the electric energy meter are initialized successfully: when the factory parameters of the electric energy meter are successfully initialized, obtaining difference items between the factory parameters of the electric energy meter after successful initialization and customer parameter setting requirements according to the customer parameter setting requirements for the factory parameters of the electric energy meter, and setting the factory parameters corresponding to the difference items to be corresponding customer parameter setting values; and when the factory parameters of the electric energy meter are not successfully initialized, trying to initialize the factory parameters of the electric energy meter again until the factory parameters of the electric energy meter are successfully initialized. The method can shorten the setting time of the factory parameters of the electric energy meter, reduce the error probability when manually setting the parameters of the electric energy meter, and improve the efficiency of the factory parameter setting of the electric energy meter.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a method for shortening the factory parameter setting time of the electric energy meter. Background technique [0002] In the existing process of setting the factory parameters of the electric energy meter using the 645 protocol (also known as the DL / T 645 communication protocol), the method of setting the factory parameters of the electric energy meter is mostly adopted one by one. Due to the small number of factory parameters involved in the 645 protocol meter, it takes about 5 minutes to set the parameters of the 645 protocol meter, which is within an acceptable range. However, compared to the DL / T 645 communication protocol, the DL / T 698 protocol is more complicated. [0003] There are more than 1,000 parameter data in the factory parameter setting items of the energy meter adopting the DL / T 698 protocol. If you follow the traditional method to set each factory paramete...

Due to the small number of factory parameters involved in the 645 protocol meter, it takes about 5 minutes to set the parameters of the 645 protocol meter, which is within an acceptable range.

However, compared to the DL / T 645 communication protocol, the DL / T 698 protocol is more complicated

[0003] There are more than 1,000 parameter data in the factory parameter setting items of the electric energy meter adopting the DL / T 698 protocol. If you follow the traditional method to set each factory parameter one by one, it will take about 15 minutes, which will greatly reduce the production efficiency of the electric energy meter.
