[0040] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:

[0041] Example 1

[0042] In this embodiment, a method for controlling a display screen in an exhibition hall based on a B / S architecture is provided. Figure 1 As shown, the exhibition hall control method includes the following steps:

[0043] S1. Establish point-to-point communication between the mobile terminal central control screen and several display screens in the exhibition hall;

[0044] S2. Marking the corresponding material databases according to the continuous setting positions of several display screens in the exhibition hall, and storing the same material preset form in all material databases;

[0045] S3, obtaining a page jump signal uploaded by a sensor set at the current display screen;

[0046] S4. Obtaining a control signal sent by the central control screen of the mobile terminal to the previous display screen corresponding to the current display screen according to the page jump signal, and extracting the material theme corresponding to the previous display screen from the control signal;

[0047] S5. Find the material theme corresponding to the current display screen in the material preset form according to the material theme corresponding to the previous display screen, and generate a corresponding control signal according to the material theme and send it to the current display screen.

[0048] Preferably, in S1, the process of the point-to-point communication is:

[0049] The mobile terminal central control screen is connected to several display screens in the exhibition hall through WEB RTC, so that the mobile terminal central control screen can communicate with several display screens in the exhibition hall through the browser.

[0050] The mobile central control screen refers to the central control PAD. The central control PAD communicates with several display screens in the exhibition hall through the browser. Through the WEB RTC front-end architecture, point-to-point communication is achieved at the browser end to ensure the real-time communication. In addition, in order to improve the smooth control of the central control PAD over the pages on the large screen, the open source (B / SD open source protocol) WebRTC technology (WebReal-Time Communication) is used to allow real-time audio, video and data sharing between web applications and mobile applications without installing any plug-ins or other software. It realizes point-to-point communication through a simple API. The first time the central control PAD and the controlled display screen connect to the handshake signaling server, a localized service is used to improve stability and response rate.

[0051] Specifically, it includes a material configuration background, several display screens in the exhibition hall, a mobile central control screen, a local signaling server, and a server. The B / S architecture is adopted for the material configuration background, several display screens in the exhibition hall, and the central control PAD. The material configuration background is used for configuration management of playback materials, including management of URL addresses of pictures, videos, and third-party service demos. The display screen is used to play the configured materials in the exhibition hall, and the central control PAD is used to control the display screen to play, switch, progress, and voice control the configured materials. The local signaling server is used to establish and manage WebRTC connections, including signaling exchange, ICE negotiation, SDP exchange, and reconnection, which can help the central control PAD and the display screen establish a WebRTC connection, and then the central control PAD and the display screen can realize P2P point-to-point communication. The server is used to provide API services such as materials and operation functions to the material configuration background, display screen, and central control PAD. In addition, the material configuration is locally stored on the edge, and nginx is deployed on the host of the display screen to map the disk material files into URL addresses for browser use, such as Figure 2 As shown, it can be seen that the server provides API services, a connection is established between the local signaling server and the display screen, and point-to-point communication can be achieved through the Google browser. Each display screen is connected to a host disk storage, that is, a material database, which is used to store the playback material corresponding to each material theme in the material preset form.

[0052] The material preset form stores multiple material information in sequence, and the material information includes the material theme and the address corresponding to the material theme. Due to the particularity of the exhibition hall scene, several display screens in the exhibition hall are often used to display the same video or multiple videos connected up and down. When the user browses the exhibition hall, he can pass through multiple display screens in sequence according to the internal structure of the exhibition hall. The operator can use the central control PAD to control the multiple display screens in sequence to play multiple videos continuously, presenting a progressive browsing effect.

[0053] like Figure 3 As shown, each display screen can be configured with a corresponding editing page. For the identification of the display screen, such as the first screen, the location information of the current display screen can be obtained, and the page location identification can be performed on the location information. The material database connected to the display screen can be configured with a corresponding material title and material URL, that is, a material theme and a material address, so that the corresponding material address can be obtained according to the material theme later, and the page jump can be realized through the material address. Among them, a material description can also be added to the material to introduce the content of the current material theme to avoid background confusion.

[0054] Preferably, the continuous arrangement positions of the plurality of display screens in the exhibition hall are arranged in a sequence relationship in advance according to the internal structure of the exhibition hall and the position information of the display screens in the exhibition hall, and a sensor corresponding to the next display screen is arranged between two display screens and close to the next display screen according to the sequence relationship, such as Figure 4 As shown, it can be seen that the sensor is arranged between display screen 1 and display screen 2 and is close to display screen 2. The sensor is used to sense that when the operator of the handheld PAD central control terminal walks to the current display screen, the page jump of the display screen is realized through the continuous relationship between the front and rear display screens, thereby improving user-friendliness.

[0055] Preferably, the page jump signal includes the position information of the sensor, and the position information of the current display screen corresponding to the sensor is obtained through the position information. The previous display screen corresponding to the current display screen is obtained according to the position information of the current display screen and the continuous setting positions of several display screens in the exhibition hall. The control signal sent by the central control screen on the mobile terminal to the previous display screen is obtained by calling the central control screen on the mobile terminal.

[0056] Preferably, the control signal includes a page jump signal and a material control signal. The page jump signal is used to actively control the display screen to perform page jump according to the control result of the operator on the previous display screen. Specifically, according to the operation control of the display screen by the operator in the actual scene, it can be known that when the operator operates to control the display screen page to jump to the material page to be controlled, the material can be controlled to perform control operations such as play and pause. Therefore, in this embodiment, the operation control of the display screen by the operator is divided into two modes: page jump and material control. According to the two different operation results, the page jump has two presentation modes: the first is: when the operator does not control the material of the previous display screen, that is, the user does not Without browsing the current material, you can jump to the to-be-played material corresponding to the previous display screen through the page. This can not only synchronize the pages of multiple display screens, but also reduce the processing volume of display screen page jumps by judging the consistency of the material themes, and avoid too much invalid processing. The second is: after the operator controls the material of the previous display screen, that is, the user has browsed the current material, you can jump to the next material corresponding to the material played on the previous display screen through the page, and connect the upper and lower display screens. The operator does not need to manually search according to the material played on the previous display screen to achieve page jumps. It only needs to control the material on the display screen to play according to the actual situation. This is more convenient and increases the friendliness to the operator.

[0057] When the material to which the page jumps on the display screen is not the material that the operator wants to play, the operator can also manually control the central control screen on the mobile terminal to send a page jump signal to the current display screen, and jump the page of the display screen according to the page jump signal. For example, for the first display screen in the exhibition hall, the first display screen does not have a corresponding previous display screen, so it can be manually controlled by the operator.

[0058] Preferably, in S4, when a control signal sent by the central control screen of the mobile terminal to the previous display screen corresponding to the current display screen is obtained according to the page jump signal, the control signal is judged. If the control signal only includes the page jump signal, the material theme corresponding to the previous display screen is extracted from the page jump signal, and the material theme is marked with a first mark; if the control signal includes a material control signal, the material theme corresponding to the previous display screen is extracted from the material control signal, and the material theme is marked with a second mark.

[0059] Preferably, the step S5 includes the following steps:

[0060] S51, obtaining the material theme corresponding to the previous display screen, identifying the mark of the material theme, if the mark of the material theme is identified as the first mark, then go to step S52; if the mark of the material theme is identified as the second mark, then go to step S53;

[0061] S52: finding the material theme in the material preset list corresponding to the current display screen according to the first mark, taking it as the material theme corresponding to the current display screen, and generating a corresponding page jump signal according to the material theme and sending it to the current display screen;

[0062] S53. Find the next material theme corresponding to the material theme in the material preset form corresponding to the current display screen according to the second mark, use the next material theme as the material theme corresponding to the current display screen, and generate a corresponding page jump signal according to the material theme and send it to the current display screen.

[0063] Example 2

[0064] On the basis of Example 1, in S2 of this embodiment, the material databases corresponding to the plurality of display screens in the exhibition hall are marked according to their continuous setting positions, and the same material preset form is stored in all material databases. The same material preset form means that the same first-level material list is stored in all material databases. The first-level material list is composed of multiple material groups sorted in sequence. For example, there are five display screens in the current exhibition hall, and the material database of each display screen stores the first-level material list {1, 2, 3, 4, 5}, and "1, 2, 3, 4, 5" indicates the first-level material list sorted in sequence. There are five material groups, each of which represents one material. One material can be split into five sub-materials, and the five sub-materials are sequentially related to the five display screens. For example, a first-level material list {1, 2, 3, 4, 5} is stored in one display screen, and material group 1 is connected to sub-material 1.1; the same first-level material list {1, 2, 3, 4, 5} is also stored in another display screen, and material group 1 is connected to sub-material 1.2; the same material groups in different material databases are connected to different materials to realize segmented data storage, which can reduce the cache amount of data in each material database and save memory.

[0065] After obtaining the material theme of the previous display screen, the corresponding material group can be located upwards according to the material theme, and the material connected to the corresponding material group can be found in the current display screen according to the material group. When users browse the exhibition hall, they can pass through multiple display screens in sequence according to the internal structure of the exhibition hall. The operator can use the central control PAD to control multiple display screens in sequence to play multiple videos continuously, presenting a progressive browsing effect.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. According to the technical essence of the present invention, within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the present invention.
