Storage method of metering data of electric power acquisition terminal, electric power acquisition terminal and electric power system

Abstract

The invention relates to a storage method of metering data of an electric power acquisition terminal, the electric power acquisition terminal and an electric power system. When the electric power acquisition terminal receives a meter reading task, the electric power acquisition terminal can make a judgment based on the number of pieces of electric meter information received by the current electricpower acquisition terminal, so that the condition that the number of pieces of the electric meter information is wrongly recorded due to the existence of a plurality of meter reading tasks is prevented; the electric power acquisition terminal also can identify and judge whether the currently read electric meter information content is in a previously read record or not, so that the stored electricmeter information content is conveniently stored, and management and data retrieval are facilitated; and once the electric meter information content is not recorded by the previous reading, a new file with reading time and an electric meter address name is created, and the currently read electric meter information content is stored in the new file, so that the effects of effectively storing the electric meter information content and easily finding the electric meter information content are achieved.

Description

technical field [0001] The invention relates to the field of power management, in particular to a method for storing metering data of a power collection terminal, a power collection terminal and a power system. Background technique [0002] my country's smart meter industry is relatively mature. According to statistics, the State Grid has accumulatively required 204.7 million smart meters, with an average demand of 40.94 million per year. The current number of power collection terminals in operation has reached more than 1 million. In the future, the growth rate of the smart meter market will remain at about 15%. [0003] Most of the current power collection terminals are installed in residential areas, and the installation locations of these power collection terminals are relatively concentrated. Once a large area of ​​power collection terminals fails, it will inevitably have a serious adverse impact on the daily life of residents. Therefore, it is very important to impro...

Problems solved by technology

[0004] However, when existing power collection terminals store metering data for electric meters, each power collection terminal is usually responsible for collecting a large number of metering data, resulting in a huge amount of metering data stored in the power collection terminal.

Once it is necessary to find the required data in the huge meter data stored in the power collection terminal, the existing method of storing meter data is difficult to meet the actual needs of quickly finding data
