Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The application provides a multi-screen display method based on a local area network, relates to the field of smart cities, and can be applied to aspects of life such as monitoring, commanding, education, security protection, video conferences and exhibition hall display. The multi-screen display method is based on a content display scheduling system and a plurality of display devices, wherein the content display scheduling system runs in background management terminal devices such as a computer, a tablet computer and a mobile phone and is used for realizing centralized display scheduling of a plurality of screens. The client is application software running on each large-screen terminal and receives and responds to display requirements and operation instructions pushed by the content scheduling system. The content display scheduling system and the client of the display device establish communication connection through a local area network, preferably, the local area network is a wireless local area network, such as a WIFI network or a bluetooth network, that is, WIFI or bluetooth communication modules are installed on the background management terminal device and each display device.
Referring to fig. 1, an embodiment of the present application provides a multi-screen display method based on a local area network, including:
s1, the content display scheduling system acquires display content;
s2, judging whether the display content needs multi-screen display;
s3, if yes, loading a plurality of preset multi-screen model packages, wherein different multi-screen model packages store different multi-screen display strategies;
s4, obtaining the selected current multi-screen model packet;
and S5, sending the display content and the current multi-screen model package to each display device, so that the client of each display device executes the display strategy of the current multi-screen model package to display the display content.
To complete the multi-screen presentation of the display contents, the display contents are first acquired, as described in step S1 above. The content which the user wants to display can be copied to the background management terminal device through storage media such as a U disk and a mobile hard disk for the content display scheduling system to read. For background management terminal equipment connected with the internet, contents which a user wants to show can be copied to the background management terminal equipment for the content display scheduling system to read in a network downloading mode such as a mailbox and a network disk downloading mode.
As described in step S2, a plurality of multi-screen model packages are preset in the present embodiment for the user to select. The multi-screen model package is an example of a multi-screen content display model, supports multiple display modes, and specifies display strategies of display contents on different screens. The multi-screen model packet can be preset to realize the quick switching of multiple display modes. For example, a multi-screen policy of a multi-screen model package may be that different screens play different pictures, and taking two display devices as an example, when a user selects a multi-screen model package in which different screens play different pictures, the two display devices display contents according to a display policy in the multi-screen model package, specifically, when contents in a text format are played, continuous file pages are displayed on the two display devices respectively and simultaneously, a page change manner is designated as manual or automatic in the display policy, if the page change manner is automatic, the display device is automatically switched to subsequent continuous file page numbers within a preset time, and if the page change manner is manual page change, the display contents are displayed as subsequent continuous file page numbers of a current page number after receiving a page change operation instruction.
As described in the above step S3, the preset multiple-screen model packages include multiple multi-screen model packages, such as a multi-screen model package supporting that all screens display the same picture, a multi-screen model package supporting that different screens display different pictures, a multi-screen model package supporting that all screens jointly display one picture, and a multi-screen model package supporting that a specific screen displays specific content, and each multi-screen model package has a corresponding display policy, and is displayed in a list form for the user to freely select.
As described in the foregoing steps S4-S5, after the user selects the multi-screen model package, the content display scheduling system sends the display content and the multi-screen model package to the client of each display device through the wireless network, and the client of each display device displays the display content according to the display policy of the device in the multi-screen model package. The primary and secondary screens of the display device can be pre-designated, and different display strategies can be designed for the primary and secondary screens in a multi-screen model package in which different screens play different contents. The process of designating the primary and secondary screens may be set on the content display scheduling system, or may be set in the client of each display device, and the client setting information of each display device is shared. The client of each display device can obtain the hardware parameter of each display device, and process the display content according to the hardware parameter. The hardware parameters comprise the resolution, the size and the like of the display equipment, and after receiving the display content and the multi-screen model packet distributed by the content display scheduling system, the client acquires the specific display content according to the playing strategy in the multi-screen model packet, processes the display content according to the hardware parameters, and displays the display content on the display equipment.
In one embodiment, the step of acquiring display content by the content display scheduling system further comprises:
the content display scheduling system scans the display equipment in the local area network and establishes communication connection with all the scanned display equipment;
the content display scheduling system detects whether the number of the connected display devices is consistent with the preset number of the display devices;
and if the device codes do not accord with the preset device codes, checking the unconnected display device according to the preset device information of the display device, and displaying the checked unconnected display device codes.
As described in the above steps, before multi-screen playing is implemented, the content display scheduling system needs to establish communication connections with all display devices, for example, if a bluetooth communication module is used for wireless communication, the content display scheduling system needs to establish bluetooth connections with all display devices. In the content display scheduling system, device information and device numbers of all display devices are preset, the device information may be MAC addresses of wireless communication modules on the display devices, different display devices are distinguished according to different MAC addresses, and different display devices are encoded, such as display device 1, display device 2, … …, and display device N. When the number of the display devices preset by the content display scheduling system is N and the display device 2 is not successfully connected, the content display scheduling system displays the fault information of the display device 2 for the user to check the reason. In addition, when the play task is relatively urgent, the content display scheduling system may also set to omit display devices that are not successfully connected, and the display policies in all the multi-screen model packages may also be automatically modified to omit the display devices that are not successfully connected. Specifically, if the multi-screen model package displays the same screen on all screens, the display strategy is not modified, and the successfully connected display equipment directly plays the display content synchronously according to the display strategy; if the multi-screen model packet displays different pictures for different screens, the content display scheduling system recodes the display equipment which is successfully connected, the specific coding rules can be sorted according to the previous preset equipment numbers, the equipment which is not successfully connected is omitted, and then the display strategy is modified to display different pictures in sequence according to the coding sequence; if the multi-screen model package displays a specific screen for the specific screen, the user may decide not to display the screen at this time, and other normally connected display devices may normally display the screen. If the multi-screen model package is the tiled display, the failure cause of the connection failure is generally repaired for the display effect, and then the tiled display is performed. When the position of the display device which is not successfully connected is not in the positive center position of the splicing device, the maximum available splicing screen which can be spliced into the same shape as the previous shape and does not comprise the display device which is not successfully connected can be selected to finish the playing of the display content. For example, the previous display screen is formed by sequentially arranging and splicing 3 × 3 display devices, when the display device at the lower left corner cannot be successfully connected and the user selects emergency play, the content scheduling system may modify the play policy of the multi-screen model package and automatically select 2 × 2 screens at the upper right part to splice and display the play content.
In one embodiment, the step of acquiring display content by the content display scheduling system further comprises:
monitoring setting signals of a main screen and a secondary screen of each display device;
and sending the setting signal to all display devices.
As described above, the primary and secondary screen settings of the display device are mainly applied to the playing requirements of different screens for displaying different contents, the general primary screen is used for playing the primary contents, the secondary screen is used for playing additional contents such as expansion of the primary contents, and the general content display scheduling system presets the primary and secondary screen settings according to the display device connected thereto. In this embodiment, the primary and secondary screens can be set by the client of each display device, the setting information is fed back to the content display scheduling system through the wireless network and stored, and when a content playing task is subsequently executed, the primary and secondary screens can be directly set at the display device, so that the method is more convenient and can better meet the actual playing requirement.
In one embodiment, the step of sending the display content and the current multi-screen model package to each display device further includes:
acquiring an operation instruction for display content;
and sending the operation instruction to the client of each display device, so that the client of each display device completes the display operation of the display content according to the received operation instruction.
As described in the foregoing steps, in the multi-screen display process, the content display scheduling system may accept an operation instruction of the user on the display content, where the operation instruction may be, for example, zooming in, zooming out, turning pages of the display content, and speeding up or slowing down the playing speed. The operation instruction of the user can be sent out by the user on the content display scheduling system, the content operation system sends the operation instruction to the client of each display device through the wireless network, and the client of each display device completes the display operation of the display content according to the received operation instruction. In another embodiment, the operation instruction may also be directly generated by the user on the client, and the client directly executes the corresponding operation instruction to complete the display operation of the display content. More specifically, the user may complete, at the client of each display device, a display operation on the display content of all the display devices, for example, apply the same display operation instruction to other display devices or apply a specific operation instruction to a specific display device, and for security, the operation instruction directly generated by the client may be authenticated, and the operation instruction passing the authentication may be forwarded to other display devices by the content display scheduling system.
In a specific embodiment, the multi-screen model package includes:
the method comprises the steps that a first multi-screen model packet supporting that all screens display the same picture is supported;
