Embodiment Construction

[0041] The application of the present invention in the power dispatching automation system is as figure 1 Shown: Establish a browser client connected to the secure three-zone WEB server, access the secure three-zone WEB server through a web browser, establish a high-speed cache on the secure three-zone data platform, and store the pre-data, channel information and channel Messages, channel information and front-end data are synchronized by the front-end server in the first zone to the WEB server in the third zone in real time through the forward physical isolation device. When the user is in an office far away from a safe area, or in a remote substation, using a normal computer or web browser on a workstation to open the pre-message viewing page, the WEB service process on the WEB server will contain a tree of the real-time status of the channel The list page is sent to the client browser and refreshed regularly by the client. After the user selects the channel to view the mess...

Abstract

The invention relates to a method for viewing a pre-message through crossing security zones. The method is used for an automatic power dispatching system. The method comprises the following steps: visiting a WEB server of a security zone III through a web browser, establishing cache on the data platform of the security zone III, storing pre-data, channel information and a channel message, after the client of the browser logs on to the WEB server of the security zone III, obtaining the real-time information of channels, selecting a channel to be reviewed, transmitting the keywords of the channel to the security zone III, and transmitting the keywords of the channel to a security zone I through forward and reverse data transmission by the security zone III; and acquiring real-time data, transmitting a required original channel message to the security zone III through forward and reverse data transmission by the security zone I, and transmitting the message to the client of the browser by the security zone III to realize that the client of the browser views the channel quasi-real-time message. Through visiting the server of the security zone III to view the information and the message of the pre-channel of the security zone I, the invention has the advantages that the operation is simple and clear, the message revealing form fits in with the practical need and the quasi-real-timeviewing speed is high.

Description

Technical field [0001] The invention is used in a power dispatching automation system, and relates to a method for checking the quasi-real-time message of a safe zone channel through the safety three zone subscription of the electric secondary system in the dispatching automation system, and is a method for checking the pre-message across safety zones method. Background technique [0002] Channel access debugging and channel operating status diagnosis of power secondary system has always been a very important work link in the construction and operation of dispatch automation. Debugging and diagnosing the running status of the channel by viewing channel messages is a frequently used method in telecontrol operation and maintenance. [0003] According to the requirements of the "National Power Secondary System Safety Protection Overall Plan", the power dispatch automation system is divided into 4 safety zones, namely: safety zone one, real-time control zone; safety zone two, non-cont...
