Method for acquiring and reporting real-time data of electric power acquisition system

Abstract

The invention discloses a method for acquiring and reporting data of an electric power acquisition system. The method is characterized by comprising the following steps of: 1) periodically acquiring data by using at least two acquirers, and storing the data after the data is acquired; and 2) periodically polling the acquirers by using a concentrator, and uploading the acquired data to the concentrator after roll calling of the acquirers by the concentrator. compared with the prior art, the method has the advantages that the method for acquiring the data by the acquirers is not controlled by the concentrator, the data of a lower electric meter is collected as much as possible, the collected data is stored, the received data is immediately uploaded to the concentrator when a roll call opportunity is obtained, and the data processing advantage of an acquisition terminal is fully utilized; and a plurality of the acquirers can work at the same time, the operation mode of the acquirers is not controlled by the concentrator, and the concentrator is only responsible for periodically polling the acquirers, so a passive mode is changed into an active mode, collection and storage of real-timedata are realized to the maximum extent, calculation is conducted according to the maximum Baud rate 9600, and acquisition of the real-time data can be accurate to seconds.

Description

technical field [0001] The invention relates to a power collection system, in particular to a method for real-time data collection and reporting of the power collection system. Background technique [0002] With the continuous and in-depth development of intelligent power collection systems, users' performance requirements for power collection equipment continue to increase. The real-time and effectiveness of data collection play a vital role in analyzing the quality of power grid operation and the accuracy of electric energy measurement. At present, the commonly used meter reading method in the industry is: the concentrator actively collects the data of the meter or collector, and transmits the data to the master station by actively reporting or calling for reading by the master station. [0003] At present, although the concept of real-time data collection also exists in the power equipment collection terminal, due to the limitation of existing technical conditions, the c...

Problems solved by technology

[0003] At present, although the concept of real-time data collection also exists in the power equipment collection terminal, due to the limitation of existing technical conditions, the collection speed is slow and the collection frequency is low, so that the real-time data loses the concept of real-time, which leads to the analysis of power grid operation quality and user usage. Incalculable systematic errors in electrical habits and line loss calculations
