Cross-safe-area real-time remote information acquisition method

Abstract

The invention relates to the technical field of information, and discloses a cross-safe-area real-time remote information acquisition method, and an acquisition card implementation method for establishing a unified standard, and the method comprises the steps: 1, establishing a visual maintenance interface, extracting an acquisition source and an information storage mode from a basic template in a guide mode, and enabling the basic template to be divided into an acquisition template and a storage template, wherein the acquisition template mainly comprises information such as an acquisition address, an acquisition mode and an acquisition frequency, and the storage template mainly comprises information such as a storage mode, a storage relationship correspondence table and an updating mode; and 2, starting the acquisition card, and automatically acquiring corresponding information from the acquisition address according to the acquisition frequency after the acquisition card is successfully started. According to the real-time remote information acquisition method based on the cross-safety zone, a real-time acquisition scheme is formed from acquisition information dynamics, acquisition real-time performance, data sharing performance and transmission reliability, heartbeat files are provided as media for information transmission, and the flexibility of data acquisition work is improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a real-time remote information collection method based on cross-safety zones. Background technique [0002] With the rapid development of the economy, the automatic dispatching of electric power has become the core business of the power grid. In addition, the rise of various automatic dispatching application systems has made the data communication between services and systems closer, thus improving the real-time performance of power dispatching automation. Security and maintainability put forward higher requirements. The power dispatching automation system is divided into four safety areas, among which Area I and Area II are production control areas, Area III and Area IV are information management areas, and each safety area needs to penetrate the safety isolation device for data exchange in file format. Enable data sharing across security zones. [0003] Therefore, for bu...

Problems solved by technology

[0005] (1) Insufficient scalability of information collection: For different types of data needs, it is necessary to build collection programs on the data provider and apply for data transmission channels on the isolation device; therefore, the collection information is fixed and cannot be changed dynamically ;

[0006] (2) Insufficient real-time information collection: Under the current implementation of cross-regional information interaction, for application data, only the data provider can initiate data interaction in the form of timing or new data arrival triggers, and the data demander cannot take the initiative. Data acquisition, therefore, when the data demander uses the data, the real-time performance of the data cannot be guaranteed;

[0007] (3) Insufficient information sharing: In the process of information collection between different businesses, even if the required information is the same, it is difficult to share. Even if sharing is done through a shared database, there will still be a large amount of data redundancy, which will affect the later business system. The construction has a great impact;

[0008] (4) It is difficult to find out in time when there is a problem with the information transmission channel: At present, the penetration isolation device is mainly through file transmission, and the availability of the channel needs to be verified by each application during the transmission process
