SCADA system data acquisition period control method and device

Abstract

Aiming at SCADA real-time data acquisition, the invention provides an SCADA system data acquisition period control method and device. The method comprises the steps of acquiring characteristic sampledata related to an actual acquisition period in advance, and training to obtain an SVR regression function. In the operation process of the acquisition system, prediction and automatic adjusting of the actual acquisition period is realized according to the actual operation state. The collection efficiency of the SCADA system and the controllability of the operation process are improved.

Description

technical field [0001] The invention relates to a data collection period control method and device, in particular to a SCADA system data collection period control method and device. Background technique [0002] Statistical machine learning is an effective method for sample analysis. The SVM support vector machine method is based on the VC dimension theory of statistical learning theory and the principle of structural risk minimization. Sample learning accuracy) and learning ability (that is, the ability to identify any sample without error) to seek the best compromise in order to obtain the best generalization ability (generalization ability). The main advantages of the support vector machine method are: 1) It is specially aimed at the limited sample situation, and its goal is to obtain the optimal solution under the existing information, not just the optimal value when the number of samples tends to infinity; 2) the algorithm will eventually be transformed into A quadrati...

Problems solved by technology

For example, in large-scale applications, the number of data points is large, and the collection is carried out according to a fixed cycle, which may cause the system resources (CPU, memory) to be in a high-load state for a long time and cannot meet the requirements of the operating indicators; It is necessary to readjust the acquisition cycle or modify the code to interrupt the system operation; when the number of clients concurrently accessing the SCADA system to request real-time data increases, it will cause the system CPU and memory pressure to increase, the real-time performance of data transmission will decrease, and the performance of the entire SCADA system will be reduced
