A method for client to acquire and display graphic files in remote browsing environment

Abstract

The invention belongs to the field of electrical power system scheduling automation and particularly relates to a method for obtaining and showing a picture file by a client side under the remote browsing environment. When the client side browses pictures of a server side, a browsing request is triggered through a human-computer interface, the human-computer interface sends the browsing request to a picture agency deployed in the local, the picture agency and a picture gateway server deployed on the server side are interacted to obtain the picture file and picture data, the picture agency forwards the file and the data obtained from the server side to the human-computer interface, and the human-computer interface shows the file and the data. Due to the fact that an agent mechanism and a multistage cache mechanism of the picture file are arranged on the client side, transmission times of the picture file between the picture agency deployed in the client side and the human-computer interface are minimum, meanwhile, the times of requests for sending the picture file to the remote picture gateway server from the picture agency are reduced, and therefore the efficiency of remotely browsing is improved.

Description

technical field [0001] The invention belongs to the field of power system scheduling automation, and in particular relates to a method for obtaining and displaying graphic files by a client in a remote browsing environment. Background technique [0002] With the development of the national economy, the scale of the power grid is also developing rapidly. In order to meet the needs of the country and improve the management level of power grid enterprises, the State Grid Corporation of China has proposed integrated regulation and control measures. The integration of regulation and control requires the integration of dispatching business and equipment monitoring business. Therefore, as the scale of the power grid continues to increase, a large amount of substation data information needs to be sent, which greatly increases the processing burden of the master station system database. For this reason, the National Electric Power Dispatching and Control Center proposed a new data in...

Problems solved by technology

The State Grid has formulated the specifications for the interaction between the server and the client under the "remote browsing" data interaction mode. As long as each manufacturer follows the relevant interaction specifications, they can browse graphics and data without barriers. However, how to achieve data interaction between the server and the client but did not stipulate
