Problems solved by technology

Due to the large header information in the http protocol and repeated polling many times, there is a large waste of bandwidth
At the same time, Ajax polling requires the server to have fast processing speed and resources, and consumes a lot of front-end resources.

Embodiment 1

[0026] This embodiment provides a method for realizing large-screen display based on Websocket, which is applied to a server. The above-mentioned server exchanges information with a user terminal running a large-screen display system through a Websocket channel, wherein the interactive information includes the information sent by the user terminal to the server. information such as the display request, as well as related information such as the display information sent by the server to the user terminal. The Websocket channel is a connection channel established between the server and the user terminal using the WebSocket protocol. A WebSocket connection is a connection established between a server and a user terminal using the WebSocket protocol. The WebSocket protocol is a network protocol based on TCP (Transmission Control Protocol, Transmission Control Protocol).

[0027] see figure 2 The flow chart of the method for realizing large-screen display based on Websocket is s...

Embodiment 2

[0044] Corresponding to the method for implementing large-screen display based on Websocket on the server side, this embodiment provides another method for implementing large-screen display based on Websocket, which is applied to user terminals, see image 3 The flow chart of the method for realizing large-screen display based on Websocket is shown, and the method includes the following steps:

[0045] In step S302, the user terminal sends a display request carrying display conditions to the server; wherein, the above display conditions include display time and / or display region.

[0046] Wherein, the display conditions include: display time and / or display region. The user inputs display conditions on the page of the user terminal, and sends information carrying the display conditions to the server. After receiving the information carrying the display conditions, the server parses the received information to obtain the display conditions, and actively pushes statistical data ...

Embodiment 3

[0053] This embodiment is described from the perspective of interaction between the server and the client terminal, see Figure 4 The flow chart of the interaction between the server and the client terminal is shown.

[0054] Step S401, the user terminal establishes a Websocket channel with the server.

[0055] Wherein, the Websocket channel may be established in the following manner: the user terminal sends a Websocket connection establishment request to the server; after receiving the connection request, the server sends a websocket connection establishment response to the user terminal. The connection request is specifically an http request, which includes additional header information "Upgrade: WebSocket", indicating that this is an HTTP request for a protocol upgrade. The user terminal receives the connection response from the server, indicating that the connection has been established. The WebSocket channel between the user terminal and the server is successfully establ...

Abstract

The invention provides a method and a device for realizing large-screen display based on Websocket, which are applied to a server. The server and a user terminal running a large-screen display systemexchange information through a Websocket channel. The method comprises the following steps: receiving a display request sent by the user terminal, wherein the display request carries a display condition including a display time and / or a display area; obtaining display information that meets the above display conditions; sending the display information to the user terminal so that the user terminaldisplays the display information through the large screen display system. The invention saves network resources and improves user experience.

Description

technical field [0001] The present application relates to the technical field of information processing, in particular to a method and device for realizing large-screen display based on Websocket. Background technique [0002] Large-screen display systems are widely used in communication, electric power, military command organizations and other scenarios. It plays an important role in providing shared information, decision support, situation display, and BSV liquid crystal splicing split screen display. Usually, the large-screen page uses the http protocol to obtain data. Specifically, the front-end (Asynchronous Javascript And XML) Ajax polls to obtain data. The front-end Ajax sends requests to the server at certain intervals, and the server replies with data to the front-end Ajax. The Ajax polling method is essentially a process in which the front-end Ajax and the server continuously establish and close connections. Since there is a large header information in the http ...
