Description

[0002] With the rapid development of communication, information, and television technologies, these technologies have played a significant role in the corporate work environment. In the course of corporate work, each department tends to control its own display devices (for example, the marketing department's screen only displays its own data and refuses to allow other departments to "borrow" it). Even if there is a need for temporary collaboration (such as sharing desktops across departments), it requires cumbersome steps such as manually copying data and reconnecting devices. When the person in charge assigns tasks that require collaboration between different departments, it is difficult to share desktop data, and congestion and errors can easily occur when multiple people try to access the task desktop.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1, as shown in Figure 1, the multi-display collaborative working method based on wireless transmission described in this example includes the following steps:

[0045] S1. Confirm the main control device and multiple wireless display devices, and pair and connect the main control device with each of the multiple wireless display devices respectively;

[0046] S2. The main control device configures the parameters of the wireless display devices. Specific configurable parameters include: resolution and display mode synchronization; the main device automatically detects the physical parameters of each display (resolution, refresh rate, color depth) and generates a unified configuration scheme in the control software (e.g., forcing all displays to use a 1920×1080 resolution). Users can manually adjust the collaboration mode: Mirror mode: all displays synchronously show the main device's desktop content; Extended mode: the main device's desktop is logically divided into multiple areas, with each display showing an independent partition. Based on the number and distance of the displays, the main device dynamically allocates wireless bandwidth (e.g., allocating a higher bitrate to nearby displays) and enables anti-interference algorithms (e.g., frequency hopping technology). For latency-sensitive scenarios (e.g., real-time operation), a "low latency mode" is enabled, compressing non-critical screen data to reduce transmission time. Specific configuration parameters are selected according to requirements, defining the desktop collaboration area of ​​the main control device. This desktop collaboration area includes multiple sub-areas, each corresponding to a wireless display device.

[0047] S3. Transmit the desktop of the sub-area to the corresponding wireless display device for display;

[0048] As described in steps S1-S23 above, the distribution layout corresponds to the desktop layout of the display rules of the sub-regions when sending the desktop. The receiving layout and the distribution layout are in a corresponding state. The desktop sent through a certain area of ​​the distribution layout will be received by the corresponding area on the receiving layout. Then, according to the position and range of the reception on the receiving layout, it will be displayed on the wireless display device. Multiple sub-regions correspond to their respective wireless display devices independently. At the same time, they can generate collaborative integration and switching functions based on the coordination points. They have a more precise collaborative effect on the wireless display device, without confusion or congestion. They can operate independently, but can also communicate and interact with each other, resulting in a flexible and accurate collaborative working effect on the wireless display device.

[0049] In one embodiment, step S1, which confirms the connection between the main control device and multiple wireless display devices and pairs the main control device with each of the multiple wireless display devices, includes:

[0050] S11, corresponding to the main control device and multiple wireless display devices, where the wireless display devices are handheld tablet displays in a uniformly laid-out network environment;

[0051] S12. Set a connection protocol for the main control device. This connection protocol can support the connection of wireless display devices, establish a connection channel between the main control device and multiple wireless display devices, and complete the pairing connection.

[0052] As described in steps S11-S12 above, firstly, the handheld tablet display screen that needs to be connected to the main control device for collaborative work is determined. This handheld tablet display screen can move its network location as needed, which facilitates collaborative work. Before the main control device connects with multiple wireless display devices, it needs to be on the same Wi-Fi network to record the network name (SSID) and password. Then, the connection protocol that can be connected to the wireless display devices is set for the main control device. After the connection environment is set up, a connection channel can be established between the main control device and multiple wireless display devices to complete the pairing connection.

[0053] In one embodiment, as shown in FIG3, step S2, which assigns the multiple sub-regions to the wireless display device respectively, includes:

[0054] S21. Set up multiple sub-regions in the main control device as desktop collaboration regions corresponding to the number of wireless display devices;

[0055] S22. For each of the multiple sub-regions, set up multiple collaboration points corresponding to the number of wireless display devices. Each collaboration point is a virtual machine in the corresponding sub-region. The virtual machine is connected to the desktop in the sub-region. Connect the multiple collaboration points in the sub-region to the sub-regions respectively.

[0056] S23. Set corresponding collaborative blank ports for each of the multiple sub-regions, configure the display device area layout and display rules for each of the multiple sub-regions, and connect the collaborative point to the collaborative blank port in the sub-region.

[0057] S24. Connect the collaborative blank ports in multiple sub-regions to the wireless display devices one by one. The collaborative blank ports are connected ports. The connection ports here are bound to the sub-regions, but are not used for direct data acquisition. Finally, the virtual machine is connected and bound together with the collaborative blank ports. Through the connection between the virtual machine and the sub-regions, the desktop data in the sub-regions is synchronized to the corresponding connected wireless display devices through the collaborative blank ports.

[0058] In one embodiment, step S23, which involves setting corresponding collaborative blank ports for each of the multiple sub-regions, configuring display device area layouts and display rules for each of the multiple sub-regions, and connecting collaborative points to the collaborative blank ports in their respective sub-regions, includes:

[0059] S231. Display device area layouts are set for each of the multiple sub-regions, wherein the display device area layout includes the desktop control unit of the corresponding sub-region;

[0060] S232. Set the distribution layout for the corresponding collaborative blank port, where the distribution layout is the storage surface of the desktop range of the corresponding sub-region;

[0061] S233. Set the number of enabled collaboration points and the desktop position and range of the corresponding collaboration points in the sub-regions as display rules for each of the multiple sub-regions.

[0062] S234. Based on display rules, connect multiple collaborative points in the sub-region to the storage surface of the corresponding sub-region desktop position and range in the collaborative blank port.

[0063] In one embodiment, step S24, which involves corresponding and connecting the cooperative blank ports in multiple sub-regions to wireless display devices one by one, includes:

[0064] S241. Set the receiving surface for the corresponding wireless display device, wherein the receiving surface is the storage surface of the desktop range of the corresponding sub-area;

[0065] S242. Establish a one-to-one correspondence between sub-regions and wireless display devices, and map and connect the distribution layout of the cooperative blank ports in the corresponding sub-regions to the receiving layout of the wireless display devices.

[0066] In one embodiment, step S242, which maps and connects the distribution layout of the cooperative blank ports in the corresponding sub-region to the receiving layout of the wireless display device, includes:

[0067] S2421. Multiple guide points are set for the corresponding collaborative blank port. Each guide point includes two enclosing groups. Each enclosing group consists of multiple marker points and a connection node. The connection nodes between the two enclosing groups are interconnected. Multiple marker points in a single enclosing group are connected to the corresponding connection node.

[0068] S2422. Based on the guide point, map and connect the cooperative blank port to the receiving surface of the corresponding wireless implementation device.

[0069] As described in steps S21-S24 above, since there are multiple wireless display devices, each working independently and needing to exchange and reference data, and requiring the ability to access and view the desktops displayed on other wireless display devices at any time, as well as switching between desktops, good collaborative work is necessary. To divide the work among the multiple wireless display devices, the main control device first needs to be divided into desktop areas, resulting in multiple sub-areas. The number of sub-areas is usually the same as the number of wireless display devices. Tasks are assigned to each wireless display device in a one-to-one correspondence, and the connections between the sub-areas are established through collaborative blank ports configured in the sub-areas. For communication connections, multiple collaboration points are set up for each sub-region. These collaboration points within the sub-regions are connected one-to-one with different sub-regions. For example, taking a sub-region as an example, the main control device has four sub-regions: Y1, Y2, Y3, and Y4. Within a single sub-region, such as Y1, there are four collaboration points: X1, X2, X3, and X4. X1 is bound to sub-region Y1, and X2 is bound to sub-region Y2, creating a one-to-one connection. Each sub-region is configured in this way. Each collaboration point is a virtual machine, capable of accessing the desktop of the corresponding sub-region and possessing communication and transmission capabilities. When wireless display... When the device only needs to display the desktop in the corresponding sub-area, the corresponding collaborative point, as the only collaborative point, activates a guide point. Then, the desktop in the sub-area acquired by the collaborative point is provided to the collaborative blank port. At this point, the collaborative point is bound to itself. The collaborative point can transmit data based on the pre-paired connection between the main control device and the corresponding wireless display device. In this way, the desktop in the sub-area where the collaborative point is located can completely cover all the storage surfaces of the distribution board. Here, the storage surface is the storage surface (cloud storage) set within the desktop range of the corresponding sub-area at the collaborative blank port. Subsequently, the collaborative blank port can be used as the transmitting end, and the storage surface can be used as a refined transmission channel for the wireless display device. For reference and differentiated display, multiple sub-regions can be displayed on the same wireless display device, and these sub-regions on the main control device will not interfere with or affect each other. Each sub-region has a corresponding collaborative surface for acquiring the desktop of other sub-regions. A receiving surface is set on the wireless display device. The receiving surface and the distribution surface are essentially the same, using the same technical architecture. The only difference in function is that the receiving surface corresponds to the desktop layout on the wireless display device, while the distribution surface corresponds to the layout when the desktop of the sub-region is sent. The receiving surface and the distribution surface are in a corresponding state. The desktop sent through a certain area of ​​the distribution surface will be received by the corresponding area on the corresponding receiving surface.Then, based on the received position and range on the receiving panel, the data is displayed on the corresponding wireless display device. Multiple sub-areas independently correspond to their respective wireless display devices. Simultaneously, based on the coordination points, they can coordinate, integrate, and switch, resulting in more precise coordination on the wireless display device. This avoids confusion and congestion, allowing each area to operate independently while also communicating with each other, achieving a flexible and accurate collaborative working effect on the wireless display device.

[0070] In one embodiment, step S3, which transmits the desktop of the sub-area to the corresponding wireless display device for display, includes:

[0071] S31. Transmit the desktop of the sub-region corresponding to the collaboration point in the desktop collaboration area to the corresponding wireless display device for display through the collaboration blank port;

[0072] S32. When the wireless display device needs to obtain the desktop in other sub-areas, it enables the corresponding collaborative point of other desktops and connects it with the collaborative blank port. According to the display rules, it obtains the desktop position and range in the sub-area corresponding to the collaborative point of the desktop in other sub-areas.

[0073] S33. Based on the desktop position and range of the collaboration points of other sub-region desktops in the sub-region, obtain the storage surface position and range of the corresponding layout in the collaboration blank port.

[0074] S34. Transmit the desktop of the current sub-region and the desktops of other sub-regions to the receiving surface of the wireless display device through the distribution surface of the corresponding collaboration points and collaboration blank ports, and display them through the wireless display device.

[0075] In one embodiment, step S34, which involves transmitting the desktop of the current sub-region and the desktops of other sub-regions to the receiving surface of the wireless display device through the distribution layout of corresponding collaborative points and collaborative blank ports, includes:

[0076] S341. Activate the corresponding number of guide points according to the number of activated collaboration points, and associate the guide points with the collaboration points;

[0077] S342. Mark one of the enclosing clusters of the guide points at the edge of the storage surface position and range of the distribution plate corresponding to the cooperative point;

[0078] S343. Transmit another enclosing group in the guide point to the receiving surface in the wireless display device, and mark multiple marker points on the edge of the storage surface position and range corresponding to the distribution surface;

[0079] S344. The desktops corresponding to multiple collaboration points are transmitted to the receiving surface of the wireless display device through the connection node in the guide point, realizing desktop collaboration between multiple wireless display devices. One wireless display device can display the screen of the corresponding sub-area of ​​the main control device. It can also display the desktops of other sub-areas on the main control device in addition to the corresponding sub-area according to the needs of the wireless display device. The desktop distribution of other sub-areas can be planned in advance through display rules. Through collaboration points and guide points, precise screen splitting can be performed, and it has a good collaborative relationship among multiple display devices.

[0080] As described in steps S31-S34 above, the collaborative point is used to bind and acquire the corresponding sub-region, acquiring the desktop of the sub-region. Then, the collaborative point is bound to a collaborative blank port, which is used as the sending end. This collaborative blank port is a pre-established connection channel that can be directly bound and used by subsequent collaborative points. For the same wireless display device, multiple collaborative points in its corresponding sub-region can simultaneously utilize a single collaborative blank port for binding and use as an input port for desktop information, and also as a sending end for information transmission. This is necessary because both the pre-set requirements of the wireless display device and the needs of temporary operators using the wireless display device require acquiring other sub-regions. The desktop of a region can be displayed jointly with the corresponding sub-region of this wireless display device, or the current desktop can be switched to display the desktop of other sub-regions. When only one sub-region needs to be displayed on the wireless display device, data transmission is carried out through the connection channel between the pre-connected sub-region's collaborative blank port and the corresponding wireless display device. A boot point is always enabled. The boot point consists of two identical enclosing groups, each containing multiple marker points and one connection node. The connection nodes in the two enclosing groups are connected, and the multiple marker points in one enclosing group are connected. The marker points are network nodes, and the connection nodes are also network nodes. When only one sub-region needs to be displayed on the wireless display device... In one of the activated guide points, multiple marker points in one enclosing cluster surround the edge of the entire distribution surface. The connecting node acts as a data correspondence point for the connection channel between the cooperative blank port and the wireless display device. Multiple marker points in another enclosing cluster surround the edge of the entire receiving surface. Data transmission is performed between the connecting nodes of the two enclosing clusters, ensuring the desktop is accurately displayed on the wireless display device. When multiple sub-regions of desktop need to be displayed on the same wireless display device, guide points corresponding to the number of sub-regions are activated, using the same method. The desktop positions and ranges of multiple sub-regions are determined separately through display rules, thus determining the marker points of the guide points corresponding to the cooperative points in the distribution surface. The location and range of the device within the distribution layout are determined according to the display rules. Then, edge marking is performed using marker points. Another enclosing element in the guide point is transmitted to the receiving layout. The edges of the corresponding location and range of the distribution layout are marked using marker points in the receiving layout. Then, the collaborative point delivers the acquired desktop through the collaborative blank port. Data is guided and matched using the distribution layout and guide points, and then transmitted to the receiving layout. The receiving layout controls the wireless display device for display, enabling collaborative work between multiple wireless display devices. This is precise and flexible, eliminating the need to temporarily establish connections between other sub-areas and wireless display devices. Connections can be directly borrowed based on the current sub-area connections, making switching and collaboration faster.

[0081] Example 2, as shown in Figure 2, the multi-display collaborative system based on wireless transmission described in this example includes:

[0082] The connection module is used to confirm the connection between the main control device and multiple wireless display devices, and to pair and connect the main control device with each of the multiple wireless display devices.

[0083] The corresponding modules are divided and connected to the connection module. They are used to configure the parameters of the wireless display device based on the main control device and to define the desktop collaboration area of ​​the main control device. The desktop collaboration area includes multiple sub-areas, and each sub-area is associated with a wireless display device.

[0084] The display module, connected to the corresponding module, is used to transmit the desktop of the sub-area to the corresponding wireless display device for display.

[0085] It should be noted that the distribution layout corresponds to the desktop layout of the sub-region display rules when sending the desktop. The receiving layout and the distribution layout are in a corresponding state. The desktop sent through a certain area of ​​the distribution layout will be received by the corresponding area on the receiving layout. Then, according to the position and range of the reception on the receiving layout, it will be displayed on the wireless display device. Multiple sub-regions correspond independently to their respective wireless display devices. At the same time, they can generate collaborative integration and switching functions based on the coordination points. They have a more precise collaborative effect on the wireless display device, without confusion or congestion. They can operate independently, but can also communicate and interact with each other, resulting in a flexible and accurate collaborative working effect on the wireless display device.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
