Detailed Description
Other advantages and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, by way of illustration, is to be read in connection with certain specific embodiments, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The traditional products generally require only 1 PC to drag n displays or display arrays, and because different pictures are required to be displayed on different screens, the PC is required to have a powerful display adapter (display card) with strong functions so as to finish the output of multiple video signals. And dedicated to a special purpose machine, the PC can only be used in a binding with a designated display device (e.g., LED display array). The above results in high equipment requirements and limited use environments. The special client needs to be properly installed, the upgrade needs to be reinstalled and adapted, and in an actual maintenance scene, the migration is difficult to properly and safely, and faults which are difficult to locate are often encountered. The upgrade action of the related operating system may also cause the unavailability of functions, and increase the operation and maintenance cost in terms of software. As is well known, C/c++ technology stack products are more prone to breakdown failures and in practice are often forced to follow some surprising conventions.
Client side schemes based on window application programs are generally limited by the characteristics of a technical framework, and can be customized and expanded in a limited manner or have high research and development cost when certain complex interactions are realized. On the premise that the user side does not have GIS, the traditional scheme is difficult to utilize map services and data widely used in the Web field, so that the display effect and the content are very limited. Traditional client products, due to their inherent nature, obviously have a stricter and lengthy release process, so facing rapid demand and data adjustment, take a long time, and cause adverse effects to be difficult to control in case of sudden accidents
Obviously, the deployment process is limited by software and hardware, so that users have to control on specific control machines respectively and watch on a designated showcase. Such a mode also results in exclusive use of equipment and products, which is inconvenient for enterprise users to reuse the facilities. The equipment deployment requirement of multi-screen display is high, the software deployment cost is high, the interactive design is not easy to expand, the map material is limited, the customization improvement cost is high, and the interactive control is inflexible.
Based on various shortcomings and limitations in the prior art, the embodiment of the application provides a communication method and a server based on a data communication protocol.

Fig. 1 shows a flow chart of a communication method based on a data communication protocol according to an embodiment of the present application, where the method includes the following steps:
step 101: the server receives the connection establishment request message sent by the control end and/or the display end, so that the authentication of each control end and/or display end is bound to the target channel.
Step 102: the server receives the state control instruction, authenticates the state control instruction, and returns a response success instruction after authentication is successful.
Step 103: the server receives a channel state update instruction, updates a state object of the target channel mapping according to the channel state update instruction, and pushes the updated state to each control end and/or display end bound with the target channel.
In one possible implementation, one channel corresponds to several control ends and/or several presentation ends; said one channel maps one state object; each channel is independent of the other.
In one possible implementation, the server includes a state management module, a channel mapping module, and an application programming interface API module.
In a possible implementation manner, the control end and the display end are accessed through a browser and built based on WEB technology, an automatic building tool Webpack and an application assembly frame Vue.
The overall architecture applicable to the embodiment of the present application adopts a B/S mode, as shown in fig. 2, and the server side provides "state management", "channel mapping" and application programming interface API functions. The client accesses through the browser to run the method provided by the embodiment of the application. The following further describes the schemes of the embodiments of the present application.
In a first aspect, a multi-port state synchronization communication protocol.
The basic process mainly comprises three parts, as shown in fig. 3: 1. establishing connection, initiated by clients (e.g. control end, presentation end) of various roles, and binding authentication to a specific channel; 2. a sending instruction, a certain end sends a control command like a server, and when the command is correct, a response success signal is returned; 3. after receiving the update command, the server updates the state object mapped by the channel, and pushes the updated state to each client (e.g. control end, display end) through connection.
In a second aspect, relationships are related to channels, state objects, client roles.
As shown in fig. 4, one channel may correspond to a plurality of control terminals. One channel may correspond to multiple presentation ends. One end can be both the control end and the presentation end. One channel maps one state object. Each channel is independent and isolated from each other.
In the embodiment of the application, the implementation scheme of converting the multi-display interface into the multi-network interface is realized. Compared with the prior art, the method realizes the synchronization technology based on the multi-screen display scene and abandons the display signal. The display state synchronization technology based on the Ethernet is realized by utilizing a data communication protocol.
In the embodiment of the application, the control and display of multi-terminal state synchronization are realized. Because the communication technology based on the data communication protocol is adopted, the states of a plurality of display ends and a plurality of control ends are consistent in the same state channel. By utilizing the multi-channel capability, 1 deployment is also realized, and the multi-channel capability of a plurality of scene showing services is realized.
Therefore, the method provided by the embodiment of the application has the following beneficial effects:
1. flexible use: because the multi-display interface is not relied on, and the data and the functions are not bound with specific control equipment or display equipment, the characteristic that a plurality of control channels run simultaneously is realized, and the multi-place multi-scene multi-machine deployment is realized. A plurality of 'state channels' can be freely established at will, and n screens can be driven independently by m state channels, and the multiple conference rooms can be simultaneously displayed according to requirements by being combined at will and not interfering with each other.
2. Deployment cost is low, compatibility is strong: based on the multi-terminal state synchronous control technology, the output of n screens can be deployed by at most n client PCs respectively, so that the flexibility of scene combination is greatly improved. In actual use, the effects of production demonstration and online debugging are achieved. Because each PC only needs to support 1 screen at least, the configuration specification of the PC is consistent with the daily office level, and the related purchasing cost is reduced. In practice, display specifications, if not identical, typically do not affect the final result.
3. Accessing the most widely used map service: since the browser-based browser operates as a browser, various mainstream third party map services and data can be accessed to the greatest extent and more easily. Because of the consistent tradition of Web technology itself advocating "hybrid development," the cost of accessing multiple services and multiple data sources is relatively low. And 3D rendering of map and data element visualization is realized by matching with the latest technical standard WebGL, and the method is comprehensively superior to the traditional technology.
4. The customization modification speed is high: because of being based on the WEB technology, the quick iteration capability is very strong. With the help of automated build tools (weback), application assembly frameworks (Vue), a portion of simple customization, several minutes of validation capability is achieved, providing feasibility for rapid response to some sudden demand scenarios.
5. Flexible operation: each display end and each control end can send out an operation instruction to influence the state of the channel, the new state (the display interface and the related control interface) can be synchronous within 20ms (communication delay), and the use experience and the degree of freedom of audience are greatly improved within the human instantaneous feeling range.
In summary, in the communication method based on the data communication protocol provided in the embodiments of the present application, the server receives the connection establishment request message sent by the control end and/or the display end, so as to bind the authentication of each control end and/or display end to the target channel; further receiving a state control instruction, authenticating the state control instruction, and returning a response success instruction after authentication is successful; and further receiving a channel state updating instruction, updating a state object of the target channel mapping according to the channel state updating instruction, and pushing the updated state to each control end and/or display end bound with the target channel. For a multi-screen display scene, a display state synchronization technology based on the Ethernet is realized by utilizing a data communication protocol. The states of a plurality of 'display ends' and a plurality of 'control ends' in the same state channel are consistent.

the channel update module 503 is configured to receive a channel status update instruction, update a status object of the target channel map according to the channel status update instruction, and push the updated status to each control end and/or display end bound to the target channel.

In one possible implementation, the server includes a state management module, a channel mapping module, and an application programming interface API module.
In a possible implementation manner, the control end and the display end are accessed through a browser and built based on WEB technology, an automatic building tool Webpack and an application assembly frame Vue.
