Multiscreen real-time interaction system based on Web technology

Abstract

The invention discloses a multiscreen real-time interaction system based on the Web technology. The multiscreen real-time interaction system comprises at least one client side, a static resource WEB server, a real-time communication server, a data interface API server, an authentication server and a large-screen controller. The client sides support Html5 webpage browsing. The static resource WEB server provides webpage codes, pictures, style definitions and / or script programs to the client sides. The real-time communication server provides a real-time communication service, pushes monitoring data to the client sides in real time and shares operation data between the client sides and transmits a control instruction to the large-screen controller according to a preset scheme. The data interface API server provides service data to the real-time communication server and pushes the services data to the client sides so that the client sides are enabled to acquire the data through an Ajax request. The authentication server provides client side access authentication. The large-screen controller is connected with large screen hardware, receives a soket instruction and performs switching of a large screen application mode.

Description

technical field [0001] The invention belongs to the technical field of computer display control, in particular to a multi-screen real-time interactive system based on Web technology. Background technique [0002] A traditional monitoring center generally consists of a PC client, a desktop monitor and a large screen. The content of the large screen is video output by the PC client and displayed on the large screen through the large screen controller. A large-screen controller can be connected to more than one video source. [0003] There are two modes for the PC client to output to the large screen display: one is that the PC client screen is the same as the large screen, which is a copy mode; the other is a computer that outputs two (or more) video sources, and the large screen It is relatively independent from the content displayed on the desktop, which is the extended mode; [0004] Usually, the PC client is operated by a supervisor. If the copy mode is used, the inter...

AI Technical Summary

Problems solved by technology

If the copy mode is used, the interactive operation of the software interface is convenient, but because the content of the desktop monitor and the large screen are the same, the amount of information displayed is limited; Move the mouse between the main interface and the large screen interface to operate different content, and the operation on the large screen is also difficult to locate the position of the mouse because of the long distance, so it is very inconvenient

At the same time, because more than one PC client is generally used in a monitoring platform, when there are more than two PC clients, the operation becomes more difficult, and the operator needs to change the keyboard and mouse to operate different clients

[0005] For the large-screen video display control of the monitoring center, there is currently no solution that can combine the copy mode and the expansion mode
