Problems solved by technology

The usual solution is that the client browser regularly sends requests to the server for updates, but this method may cause a certain time error
In the power metering business production scheduling platform, the device sends its status information to the server in real time, and the server sends the obtained device status information to the browser after receiving the timing request from the client browser. Since the power metering business production scheduling platform The real-time requirements are high, so this method is not suitable
In addition, when the server has no data update, the client browser will still send a request to obtain data, which increases the burden on the server and network transmission

Embodiment Construction

[0022] like figure 1 As shown, the present invention relates to 3 mutually cooperative parts: equipment, server and client browser, adopt to load Flex control on client browser so that browser and server are established Socket connection in B / S system, like this You can use the Flex control as an intermediate layer to connect the Web page on the client browser and the server for Socket communication. The Flex control on the client browser and the server can send data to each other, control and call each other, so as to realize the server's active The purpose of pushing updated data. Therefore, when the device sends its status information to the server in real time, the server will actively send the obtained status information to the client browser. In addition, the client browser can also actively request information from the server through the Flex control.

[0023] like figure 2 Shown, the specific steps of the workflow of the present invention are as follows:

Abstract

The invention discloses an active transmission method for real-time Web data. A Flex control is loaded on a client browser, thereby establishing Socket connection between the browser and a server in a browser/server (B/S) system. In such a way, a Web page on the client browser can be connected with the server for Socket communication by utilizing the Flex control as an intermediate layer, and mutual data transmission and mutual control and calling can be realized between the Flex control on the client browser and the server, thereby fulfilling the aim of actively transmitting updated data by the server. When the data of the server is updated, the latest data can be transmitted to the Flex control of the client browser by Socket in real time, so the real-time performance of the data of the client browser is enhanced, and the pressure of the server and a network is reduced.

Description

technical field [0001] The invention relates to a method for pushing real-time Web data, in particular to a method for actively pushing real-time Web data used in a power metering service production scheduling platform. Background technique [0002] At present, in the power metering business production scheduling platform, it is necessary to monitor the working status and related data of the equipment in the client browser, and due to the importance of the work, these data are required to be displayed in real time. In this case, the traditional browser timing request mode does not meet the requirements. A typical server-client browser interaction looks like this: [0003] (1), the client browser makes a request; [0004] (2) The server receives the request from the client browser and analyzes and processes it; [0005] (3) The server returns the running processing result to the client browser. [0006] Usually a server needs to provide services to multiple clients, so fo...
