A remote retrieval method for displaying multi-source data on the same graph

Abstract

The invention discloses a remote access method for displaying multi-source data in the same picture, comprising the following steps: 1) the graphic browser of the main access system parses the graphic file, and obtains keyword information of the system equipment to be accessed; 2) data refresh The client will classify the same graphic file according to the keyword information to be accessed by different system devices; 3) The data refresh server will establish a data cache; Send a data request, the system graphics gateway machine gets the request, and sends the data to the data refresh server; 5) The data refresh server of the main access system detects that the cached data has changed, and returns the changed data to the data refresh client; 6) The graphical browser of the main access system refreshes the corresponding equipment data information, shortens the time for dispatchers to find problems, improves the security of the power grid, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of power grid dispatching automation, and in particular relates to a remote accessing method for satisfying the remote accessing of multi-system data by a dispatching automation system and displaying multi-source data in the same diagram. Background technique [0002] With the rapid development of power grid technology, newer and higher requirements are put forward for power grid operation dispatching and monitoring control. The system structure and function combination of traditional power grid dispatching automation system should be adjusted and changed accordingly. In order to adapt to this change, it is necessary to develop the contemporary power grid dispatching automation system to a high degree of informatization, intelligence, integration and automation. [0003] At present, there are mainly the following methods for remote browsing among various systems in the power grid: 1. KVM working mode, which ...

Problems solved by technology

[0005] The technical problem solved by the present invention is to overcome the existing remote browsing method among the various systems of the power grid. The KVM working mode has the problems of high network channel requirements, limited transmission distance, and slow response; the remote terminal mode can only be accessed at a certain moment. Browsing a certain system within the system is time-consuming and labor-intensive, which seriously affects the efficiency of scheduling and monitoring personnel to monitor data and deal with problems
