Method for reading multiple electric energy meters generally

Abstract

The invention relates to a method for reading multiple electric energy meters generally, comprising the following steps of: (A) establishing an electric energy meter protocol library platform, providing a uniform parameter initialization API (Application Program Interface)interface, a uniform physical channel initialization API interface and a uniform common data item reading API interface by the electric energy meter protocol library; (B) inputting a uniform meter reading parameter through the uniform parameter initialization API interface; (C) initializing a meter-reading physical communication interface through the uniform physical channel initialization API interface; (D) self-adapting different electric energy meter protocols by the electric energy meter protocol library platform; and (E) reading the electric energy meter protocol data through the uniform common data item reading API interface. Through the method, the meter-reading function modularization is achieved; the methodis independent, easy for management, transplantation and use, and can be conveniently and flexibly utilized for different electric energy acquisition function products and greatly save the explorative resources.

Description

technical field [0001] The present invention relates to the meter reading application of each electric energy acquisition system of the electric power system, specifically, when each electric energy acquisition system in the electric power industry is compatible with reading electric energy meters of various different protocol types at the same time, each protocol conversion is adaptively performed The software method of copying. Background technique [0002] At present, in the electric power industry, the data reading of electric energy meter data is the basic application requirement of integrated systems such as load control, distribution transformer, metering, and centralized reading. Due to historical reasons, the current meter reading communication protocols provided by various electric energy meter manufacturers vary widely and are not compatible with each other. Most of the communication protocols for imported electric energy meters are defined by themselves or adopt...

Problems solved by technology

The first two situations will inevitably lead to repeated coding and modification of the software, which is not universal, incompatible, and a lot of work is repeated

The compatibility of the latter two cases is relatively strong, but because the data content defined by the 645 agreement issued by the Ministry is not comprehensive enough, and the data format is limited, the data accuracy is not high, so it is difficult to be compatible with high-precision foreign meters such as Hongxiang.

Moreover, if the hardware products of the meter reading protocol converter are used, not only the cost of the meter reading manufacturer will be increased, but the application limitations will be even greater.
