Embodiment Construction

[0041] The application of the present invention in electric power dispatch automation system is as figure 1 Shown: Establish a browser client connected to the WEB server in the security zone 3, access the WEB server in the security zone 3 through a web browser, build a cache on the data platform in the security zone 3, and store pre-data, channel information and channels Messages, channel information and front-end data are synchronized from the front-end server in the first security zone to the WEB server in the third security zone in real time through the forward physical isolation device. When the user is in an office far away from the security zone 1, or in a remote substation, and uses a common computer or a web browser on a workstation to open the front-end message viewing page, the WEB service process on the WEB server will contain a tree view of the real-time status of the channel The list page is sent to the client browser and refreshed periodically by the client. Aft...

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 an electric power dispatching automation system, and relates to a method for subscribing and viewing quasi-real-time messages of a channel in the first safe area through the three safe areas of the electric power secondary system in the dispatching automatic system, and is a method for viewing pre-set messages across safe areas method. Background technique [0002] The channel access debugging and channel operation status diagnosis of the power secondary system have always been very important work links in the construction and operation of dispatching automation. Debugging and diagnosing channel operation status by viewing channel messages is a method frequently used in telecontrol operation and maintenance. [0003] According to the requirements of the "National Power Secondary System Safety Protection Overall Plan", the power dispatching automation system is divided into 4 safety areas, namely: safety area 1, real-time contr...
