Real-time monitoring supervising method for WEB mode of power SCADA (Supervisory Control And Data Acquisition) on basis of combining SVG (Scalable Vector Graphics) with RIA (Rich Internet Application)

Abstract

The invention discloses a SCADA (Supervisory Control And Data Acquisition) WEB monitoring method applied to the field of an electric power automation system. According to the method provided by the invention, the technology of automatically generating a SCADA monitoring graphics through a power component template on the basis of SVG (Scalable Vector Graphics) and RIA (Rich Internet Application), GSOAP and Comet technologies are combined for accessing data, a JSON (JavaScript Serialized Object Notation) data exchange mode is taken, and the monitoring graphics is real-time dynamically rendered, so that a WEB real-time monitoring function for a SCADA system is realized, an ideal of modeling and imaging integration is reflected, the high efficiency and reliability of network and data transmission and access are ensured, the information synthetic operation is performed through the technology of integrating element comprehensive data of the monitoring graphics, and a condition is created for establishing an intelligent scheduling system.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation, and relates to the WEB double vision technology in the electric power automatic monitoring system. Background technique [0002] The traditional double vision system mostly adopts the C / S mode (client / server mode), which requires a special installation of the client program, weak distribution function, unable to achieve rapid deployment, and poor compatibility. Although the ordinary Web diplopia system adopts the B / S mode (browser / server mode), it is difficult to satisfy the refreshment of real-time information. The common method is that after the client initiates a request regularly, the server returns the processing result and related information. The extra content needs to refresh the entire page, which will occupy a relatively large network bandwidth, making it difficult to implement real-time information update in WEB services. The common solution is to develop Acti...

[0002] The traditional double vision system mostly adopts the C / S mode (that is, the client / server mode), which requires a special installation of the client program, the distribution function is weak, it cannot be quickly deployed, and the compatibility is poor

Although the ordinary Web diplopia system adopts the B / S mode (browser / server mode), it is difficult to satisfy the refreshment of real-time information. The common method is that after the client initiates a request regularly, the server returns the processing result and related information. The extra content needs to refresh the entire page, which will occupy a relatively large network bandwidth, making it difficult to implement real-time information update in WEB services

The common solution is to develop ActiveX controls to handle content updates. The disadvantage is that the service function needs to be downloaded from the client to realize the service function, which does not meet the requirements of "thin" customers.

Most monitoring diagrams use drawing tools to directly draw SVG diagrams, which is cumbersome and complicated, and cannot meet the requirements of flexible group diagrams
