Description

Web-based large screen control system and method Technical Field The invention relates to the technical field of communication, in particular to ‌ ‌ a large-screen control system and method based on Web. Background Data visualization is one of the most popular research fields for big data analysis, and is a process for researching how to display information implicit in data by using visual elements such as charts, graphs, maps and the like and develop rules contained in the data. Visualizing the data analysis results can help people extract knowledge from the information, and harvest value from the knowledge. The large data screen is used as one of the display forms of the data visualization technology, can perform visual display on complex multi-source data in a limited window, presents business insights hidden behind instant change of complex data in real time, and is widely applied to various fields such as finance, medical treatment, urban traffic and the like. Before the idea of separating control and display is popularized, the traditional Web large screen project mainly adopts the following modes: The monolithic architecture, control logic (e.g., layout adjustment, data screening) is tightly coupled to the presentation pages, typically developed, deployed and run as a whole. The limited remote control is that part of the system realizes basic remote instruction transmission, but adopts modes such as HTTP polling and the like, has lower real-time performance and has single control function (for example, only the whole screen content can be switched). Tightly coupled presentation control, i.e. control of presentation content (such as play order, chart type) is usually deeply bound with business logic codes or back-end configuration files, and is difficult to flexibly adjust. These conventional approaches expose limitations when dealing with complex, highly interactive, large screen requirements. The main problems are as follows: 1. the coupling degree is high, development and maintenance are difficult, and the control end and the display end are deeply bound, so that the control end and the display end cannot be independently developed, tested and upgraded. Minor modifications on either side can cause unpredictable problems, increasing system complexity and maintenance costs, and reducing development efficiency. 2. The traditional control mode is not responsive in real time enough, and obvious delay sense exists. The control function is also often single and fixed, and complex interactive operations (such as drilling, screening or highlighting a certain chart) are difficult to support, so that the smoothness and depth of the demonstration are limited. 3. The adaptation and expansibility are insufficient, and due to the rigidity of the architecture, the traditional scheme is difficult to flexibly adapt to screens with different sizes and resolutions. When new display content or control functions are required to be added, a large amount of modification is usually required to the whole system, and the expandability is poor. 4. Data and logic are intermixed, and front-end business logic codes are often intermixed with presentation data (especially presentation data). This reduces both the readability and maintainability of the code and makes it difficult to flexibly modify the presentation at either the front-end or the back-end. Therefore, how to provide a large-screen control system with timely response, low coupling degree and stronger expansibility becomes a technical problem to be solved. Disclosure of Invention Aiming at the defects of the prior art, the application provides ‌ ‌ a large-screen control system and a method based on Web, which are used for solving the technical problems of untimely response, high coupling degree and poor expansibility of a large-screen display system in the prior art. In order to achieve the purpose of the application, in a first aspect, the application provides a large screen control system based on Web, which comprises a server gateway, at least one control end and a plurality of large screen display ends; the server gateway is respectively in bidirectional network communication with at least one control end and a plurality of large screen display ends; The control end is used for sending a registration request and an operation instruction to the server gateway; the large screen display end is used for sending a registration request to the server gateway and executing an operation instruction forwarded by the server gateway; the server gateway is used for: According to registration requests of a control end and a large screen display end, network communication with the control end and the large screen display end is respectively established, a control end ID, a large screen display end ID, a control end communication channel and a large screen display end communication channel are recorded in a registry, an operation instruction sent by the control end is analyzed to
