Problems solved by technology
This mechanism has a large amount of data interaction traffic and a large amount of calculation on the client side. It is difficult to cope with narrowband network conditions, that is, screen browsing when the screen viewing end and real-time data service are not in the same place. As a result, when multiple clients remotely browse remote system screens through narrowband networks, Severe loading delays, poor performance, or even unbrowsable

Embodiment Construction
[0035] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0036] The invention provides an EMS man-machine picture monitoring system based on picture calculation services, which includes a picture calculation server and a lightweight graphics client.
[0037] The present invention also provides a method for realizing the EMS man-machine picture monitoring system based on the picture calculation service. The method breaks the traditional man-machine graphics working mode and splits the EMS man-machine graphics system into picture calculation services and lightweight graphics clients , Separate the graphics drawing from the data calculation, the screen calculation server and the client transmit data incremental change information according to the "vector data compression" method, and the realized functions include the following parts:
[0038] ①Start the screen computing service at the service nod...

The present invention relates to an EMS human-machine screen monitoring system based on screen computing services and an implementation method. The method includes: starting the screen service of the corresponding application on the main and standby machines of different EMS applications, and one application corresponds to at least two screen services to realize the service Load balancing and mutual backup; the screen service monitors the screen subscription request of the client; the client submits the screen subscription request to the screen service; the screen service creates a calculation thread corresponding to the screen and manages the session information of the subscription client, and the calculation thread calculates the screen changes in real time, and the When the screen changes, the vector-compressed data is pushed to all subscribing clients to realize the client screen refresh. The present invention uses drawing calculation as a service, and pushes the picture drawing change amount to the graphics client only when the picture actually changes, which greatly reduces the network bandwidth required for picture refresh; through the distributed parallel picture service, the client calculation is effectively reduced. pressure to realize EMS screen browsing on the handheld mobile terminal.
Description
Technical field [0001] The invention relates to a power system computer and graphic display technology, in particular to an EMS man-machine picture monitoring system based on picture calculation services and an implementation method. Background technique [0002] EMS (Energy Management System) is a modern power grid dispatch automation system based on computers. The energy management system architecture is supported by the basic platform, and is oriented to the business application requirements of grid operation monitoring and warning, grid adjustment control, grid operation analysis and evaluation, grid dispatching plan, and grid dispatching management, forming real-time monitoring and early warning, dispatching plan, Four types of application functions for safety check and dispatch management. [0003] The basic platform of energy management system provides unified model, data, CASE, network communication, man-machine interface, system management and other services for various a...
