In many cases, people hope to display the information carried by these terminals on a public display terminal to achieve multi-terminal collaborative interaction. For example, when building a web page, you want to use a public smart screen to build the location information of different web pages. However, faced with display requests from many terminals, how to achieve efficient, orderly, and reasonable collaborative display has become an urgent problem to be solved.

[0003] Based on this, the present invention provides a smart screen multi-terminal collaborative interaction system and method based on edge computing to solve the technical problems raised above. Summary of the Invention

When the levels are the same or there are no levels, the decisions are made based on feature information, which makes the results more reasonable and avoids random or average distribution of displays. At the same time, the memory usage of the smart screen is monitored in real time, and the display request is suspended when the threshold is reached, ensuring the smooth operation of the system. In addition, the historical information features are continuously updated to improve the intelligence and adaptability of the entire system.

[0005] To achieve the above object, the present invention provides the following technical solutions:

The edge computing unit is connected to the terminal display unit;

[0009] The smart screen display unit is used to provide the smart screen required for display, and the smart screen display unit is connected to both the terminal display unit and the edge computing unit.

[0010] The present invention is further configured as follows: the terminal display unit includes a terminal module and a first communication module, wherein:

[0011] The terminal module is used to send a display request to the edge computing node, and perform collaborative interactive display according to the received judgment result of the edge computing node;

[0013] The present invention is further configured as follows: the edge computing unit includes a second communication module and a feature extraction module, wherein:

[0014] The second communication module is used to realize information interaction between the edge computing unit and the terminal display unit and the smart screen display unit;

[0015] The feature extraction module obtains historical information features based on the historical information in the display state of the smart screen and the display information of each corresponding terminal, and the feature extraction module is connected to the second communication module;

[0016] The process of obtaining historical information features is as follows:

[0017] Based on the display information of each terminal in the display state of the smart screen with priority permissions, calculate the comprehensive value of the historical priority permissions of each terminal Where H i is the comprehensive value of historical priority authority of the i-th terminal, x in is the number of times when the permission level is n, and the permission level of permission level n-1 is better than the permission level of permission level n, α n is the weight coefficient, and 0<α n <α n-1 ;

[0018] Sort the terminals by their comprehensive priorities according to their historical priority comprehensive values to obtain first feature information;

[0019] Based on the display information of each terminal without priority permission, calculate the historical non-priority permission comprehensive value of each terminal Where y jm is the historical display times of terminal m, P jm is the average memory usage of the smart screen used by terminal m to display historical information. β1 and β2 are both weight values, β1+β2=1, and β1>β2;

[0020] According to the size of the comprehensive value of the historical no-priority authority of each terminal, the terminals are sorted by comprehensive priority to obtain the second characteristic information.

[0021] The present invention is further configured such that: the edge computing unit further includes a request adjudication module and a database module, wherein:

[0023] The process of determining the display request of each terminal is as follows:

[0024] The edge computing node extracts the current display request priority level of each terminal from the display request, and releases the corresponding display request in order of priority level. At the same time, it monitors the memory usage of the smart screen and compares it with the preset security threshold. If the preset security threshold is reached, the release of the display request is suspended.

[0025] Within the preset security threshold, if the priority authority levels are the same, the first feature information of the corresponding terminal is retrieved, and the historical priority authority comprehensive values of the corresponding terminals are compared, and the display request of the terminal with the higher historical priority authority comprehensive value is preferentially approved;

[0026] Within the preset security threshold, if the terminal has not set a priority permission level for the current display request, the second feature information of the corresponding terminal is retrieved, and the comprehensive value of the historical no priority permission of the corresponding terminal is compared, and the display request of the terminal with the higher comprehensive value of the historical no priority permission is prioritized;

[0027] The database module is used to store historical information under the display status of the smart screen, as well as the display information of each corresponding terminal and the acquired historical information features.

[0032] The second aspect of the present invention is to provide a method for collaborative interaction of multiple terminals on a smart screen based on edge computing, comprising the following steps:

[0033] Obtain historical information features based on the historical information displayed on the smart screen and the corresponding display information of each terminal;

[0034] During the first cycle of the smart screen display, each terminal sends a display request to the edge computing node. The edge computing node adjudicates the display request of each terminal based on the received display request and feeds back the corresponding adjudication result. Based on the adjudication result, each terminal collaboratively and interactively displays on the smart screen.

[0035] After the smart screen completes the first cycle of display, it updates the historical information features. In the second cycle, it re-determines the display requests of each terminal and feeds back the corresponding determination results. Each terminal will collaboratively and interactively display on the smart screen based on the determination results.

[0036] The present invention is further configured as follows: the display status includes a smart screen display status based on priority permissions and a smart screen display status based on no priority permissions.

[0037] The present invention is further configured as follows: the process of obtaining the historical information features is as follows:

[0038] Based on the display information of each terminal in the display state of the smart screen with priority permissions, calculate the comprehensive value of the historical priority permissions of each terminal Where H i is the comprehensive value of historical priority authority of the i-th terminal, x in is the number of times when the permission level is n, and the permission level of permission level n-1 is better than the permission level of permission level n, α n is the weight coefficient, and 0<α n <α n-1 ;

[0039] Sort the terminals by their comprehensive priorities according to their historical priority comprehensive values to obtain first feature information;

[0040] Based on the display information of each terminal without priority permission, calculate the historical non-priority permission comprehensive value of each terminal Where y jm is the historical display times of terminal m, P jm is the average memory usage of the smart screen used by terminal m to display historical information. β1 and β2 are both weight values, β1+β2=1, and β1>β2;

[0041] According to the size of the comprehensive value of the historical no-priority authority of each terminal, the terminals are sorted by comprehensive priority to obtain the second characteristic information.

[0042] The present invention is further configured as follows: the process of determining the display request of each terminal is as follows:

[0043] The edge computing node extracts the current display request priority level of each terminal from the display request, and releases the corresponding display request in order of priority level. At the same time, it monitors the memory usage of the smart screen and compares it with the preset security threshold. If the preset security threshold is reached, the release of the display request is suspended.

[0044] Within the preset security threshold, if the priority authority levels are the same, the first feature information of the corresponding terminal is retrieved, and the historical priority authority comprehensive values of the corresponding terminals are compared, and the display request of the terminal with the higher historical priority authority comprehensive value is preferentially approved;

[0045] Within the preset security threshold, if the terminal has not set the priority permission level for the current display request, the second feature information of the corresponding terminal is retrieved, and the historical comprehensive value of no priority permission of the corresponding terminal is compared, and the display request of the terminal with a higher historical comprehensive value of no priority permission is prioritized.

[0046] The present invention is further configured as follows: the process of updating the historical information feature is as follows:

[0047] The information on the display status of the smart screen in the first cycle and the corresponding display information of each terminal are used as historical data to re-obtain historical information features.

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] The present invention obtains first and second feature information by comprehensively prioritizing each terminal. In the process of feature information extraction, multiple factors such as permission level, historical number, and memory occupancy are taken into account, so that feature extraction can more accurately reflect the display needs and importance of each terminal in different situations. The display requests of each terminal are released in turn according to the priority permission level, which reflects the priority processing of important or urgent display requests and ensures that key information can be displayed on the smart screen in a timely manner. When the priority permission levels are the same or no priority permission level is set, the corresponding feature information is retrieved and the display request of the terminal with the highest comprehensive value is released. The display status of each terminal reflected by the historical data is fully utilized, making the ruling result more reasonable and avoiding the situation of simply random or average distribution of display opportunities. At the same time, the memory occupancy of the smart screen is monitored in real time during the ruling process and compared with the preset safety threshold. When the preset safety threshold is reached, the release of the display request is suspended, effectively preventing system crashes or freezes caused by too many terminals displaying at the same time, ensuring the smoothness of the system. In addition, by continuously updating the historical information features, the intelligence and adaptability of the entire system are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0057] Example:

[0058] like Figures 1-4As shown, this embodiment provides a smart screen multi-terminal collaborative interaction system based on edge computing, including a terminal display unit 100, an edge computing unit 200 and a smart screen display unit 300, wherein: the terminal display unit 100 is used to provide the corresponding terminal to the operator, send a display request through the terminal, and perform a collaborative interactive display based on the received judgment result; the edge computing unit 200 is used to provide an edge computing node, and the edge computing node obtains historical information characteristics and judges the display request of each terminal based on the historical information under the display status of the smart screen and the display information of the corresponding terminals. The edge computing unit 200 is connected to the terminal display unit 100; the smart screen display unit 300 is used to provide the smart screen required for the display, and the smart screen display unit 300 is connected to both the terminal display unit 100 and the edge computing unit 200.

[0059] In this embodiment, it should be noted that the edge computing unit 200 obtains information of the terminal display unit 100 and the smart screen display unit 300. First, based on the historical information under the display status of the smart screen and the display information of the corresponding terminals, the edge computing unit 200 will obtain the historical information characteristics, that is, obtain the first characteristic information and the second characteristic information, and then combine the priority authority and the non-priority authority to make subsequent judgments. According to the judgment result, the corresponding result is fed back to the terminal display unit 100, so that each terminal can reasonably interact collaboratively on the smart screen display unit 300 and ensure the smoothness of the smart screen.

[0060] In the present invention, the terminal display unit 100 includes a terminal module 110 and a first communication module 120, wherein: the terminal module 110 is used to send a display request to the edge computing node, and to perform collaborative interactive display based on the received judgment result of the edge computing node; the first communication module 120 is used to realize the connection between the terminal display unit 100 and the edge computing unit 200 and the smart screen display unit 300.

[0061] In this embodiment, it should be noted that the operator can send a display request through the terminal module 110, and the display request will be uploaded to the edge computing unit 200 through the first communication module 120. The edge computing unit 200 will determine whether it is passed. When receiving the feedback result, if it is not passed, the operator can control the smart screen display unit 300 to display the required information through the terminal module 110. As an example, when making an animation video, you can use different terminals, including but not limited to computers, mobile phones, etc., to send display requests such as dubbing and subtitle preparation to the edge computing unit 200. After the determination is passed, different terminals can interact collaboratively to achieve collaborative processing of animation video production in the smart screen.

[0062] In the present invention, the edge computing unit 200 includes a second communication module 210 and a feature extraction module 220, wherein: the second communication module 210 is used to realize information interaction between the edge computing unit 200 and the terminal display unit 100 and the smart screen display unit 300; the feature extraction module 220 obtains historical information features based on the historical information under the smart screen display state and the display information of each corresponding terminal. The feature extraction module 220 is connected to the second communication module 210;

[0063] The process of obtaining historical information features is as follows:

[0064] Based on the display information of each terminal in the display state of the smart screen with priority permissions, calculate the comprehensive value of the historical priority permissions of each terminal Where H i is the comprehensive value of historical priority authority of the i-th terminal, x in is the number of times when the permission level is n, and the permission level of permission level n-1 is better than the permission level of permission level n, α n is the weight coefficient, and 0<α n <α n-1 ;

[0065] Sort the terminals by their comprehensive priorities according to their historical priority comprehensive values to obtain first feature information;

[0066] Based on the display information of each terminal without priority permission, calculate the historical non-priority permission comprehensive value of each terminal Where y jm is the historical display times of terminal m, P jm is the average memory usage of the smart screen used by terminal m to display historical information. β1 and β2 are both weight values, β1+β2=1, and β1>β2;

[0067] According to the size of the comprehensive value of the historical no-priority authority of each terminal, the terminals are sorted by comprehensive priority to obtain the second characteristic information.

[0068] In this embodiment, it should be noted that the historical information of the terminal display unit 100 and the smart screen display unit 300 can be received through the second communication module 210, and the feature extraction module 220 obtains the historical information features based on the historical information under the display status of the smart screen and the display information of each corresponding terminal. The historical information features obtained include first feature information and second feature information, and then the historical information can be divided based on priority authority to facilitate the subsequent determination of the display requests of each terminal, so as to avoid all display requests pouring into the smart screen display unit 300 under the same priority authority or no priority authority, causing the smart screen memory to overload and affecting the smoothness of the smart screen operation. At the same time, it can effectively ensure that general and critical display requests can be displayed in a timely manner.

[0069] In the present invention, the edge computing unit 200 further includes a request adjudication module 230 and a database module 240 , wherein: the request adjudication module 230 adjudicates the display request of each terminal based on the display request received from each terminal, and feeds back the corresponding adjudication result. The request adjudication module 230 is connected to both the second communication module 210 and the feature extraction module 220 ;

[0070] The process of judging the display request of each terminal is as follows:

[0071] The edge computing node extracts the current display request priority level of each terminal from the display request, and releases the corresponding display request in order of priority level. At the same time, it monitors the memory usage of the smart screen and compares it with the preset security threshold. If the preset security threshold is reached, the release of the display request is suspended.

[0072] Within the preset security threshold, if the priority authority levels are the same, the first feature information of the corresponding terminal is retrieved, and the historical priority authority comprehensive values of the corresponding terminals are compared, and the display request of the terminal with the higher historical priority authority comprehensive value is preferentially approved;

[0073] Within the preset security threshold, if the terminal has not set a priority permission level for the current display request, the second feature information of the corresponding terminal is retrieved, and the comprehensive value of the historical no priority permission of the corresponding terminal is compared, and the display request of the terminal with the higher comprehensive value of the historical no priority permission is prioritized;

[0074] The database module 240 is used to store historical information of the smart screen display status, as well as the display information of each corresponding terminal and the acquired historical information features. The database module 240 is connected to the second communication module 210, the feature extraction module 220 and the request arbitration module 230.

[0075] In this embodiment, it should be noted that the request determination module 230 will receive the feature information extracted by the feature extraction module 220, and combine the display requests received from each terminal to determine whether the display requests of each terminal are released, that is, whether they are passed. When a display request priority permission level is set, the display request priority permission level is taken as the first priority, and within the preset security threshold of the smart screen memory, the corresponding display requests are determined to be released in turn. At the same time, the smart screen memory occupancy rate will be monitored in real time to ensure the smooth operation of the smart screen and to ensure that display requests with high display request priority permission levels can be released first. When the priority permission levels are the same, the historical non-priority permission comprehensive value will be used to select the corresponding display request for display. In addition, when the priority permission level of the current display request is not set, the historical non-priority permission comprehensive value will be used to select the corresponding display request for display.

[0076] In the present invention, the smart screen display unit 300 includes a smart screen module 310, a memory detection module 320 and a third communication module 330, wherein: the smart screen module 310 is a smart screen for displaying multi-terminal collaborative interactive information; the memory detection module 320 is used to monitor the occupancy rate of the smart screen memory required for display of each terminal, and the memory detection module 320 is connected to the smart screen module 310; the third communication module 330 is used to realize information interaction between the smart screen display unit 300 and the terminal display unit 100 and the edge computing unit 200.

[0077] In this embodiment, it should be noted that the memory detection module 320 monitors the memory usage information of the smart screen in real time and uploads it to the edge computing unit 200 through the third communication module 330 for the edge computing unit 200 to determine the display request.

[0078] In addition, this embodiment also provides a smart screen multi-terminal collaborative interaction method based on edge computing, including the following steps:

[0079] Step 1: Obtain historical information features based on the historical information under the display status of the smart screen and the display information of each corresponding terminal.

[0080] Among them, the display status includes the display status of the smart screen based on priority permissions and the display status of the smart screen based on no priority permissions.

[0081] The process of obtaining historical information features is as follows:

[0082] Based on the display information of each terminal in the display state of the smart screen with priority permissions, calculate the comprehensive value of the historical priority permissions of each terminal Where H i is the comprehensive value of historical priority authority of the i-th terminal, x inis the number of times when the permission level is n, and the permission level of permission level n-1 is better than the permission level of permission level n, α n is the weight coefficient, and 0<α n <α n-1 ;

[0083] Sort the terminals by their comprehensive priorities according to their historical priority comprehensive values to obtain first feature information;

[0084] Based on the display information of each terminal without priority permission, calculate the historical non-priority permission comprehensive value of each terminal Where y jm is the historical display times of terminal m, P jm is the average memory usage of the smart screen used by terminal m to display historical information. β1 and β2 are both weight values, β1+β2=1, and β1>β2;

[0085] According to the size of the comprehensive value of the historical no-priority authority of each terminal, the terminals are sorted by comprehensive priority to obtain the second characteristic information.

[0086] In this embodiment, it should be noted that by analyzing and calculating the display information of each terminal under two different smart screen display states, namely, with priority permissions and without priority permissions, the corresponding characteristic information, namely the first characteristic information and the second characteristic information, can be obtained. The different performances of each terminal in the past display can be fully grasped, and a multi-dimensional basis can be provided for the subsequent determination of display requests. As an example, it is assumed that three permission levels are set, namely, permission level 1 (highest), permission level 2 (intermediate), and permission level 3 (lowest). Terminal A appeared 3 times at permission level 1 and 5 times at permission level 2; Terminal B appeared 4 times at permission level 2 and 6 times at permission level 3; Terminal C appeared 8 times at permission level 3. Assuming the weight coefficients α1 to be 0.5, α2 to be 0.3, and α3 to be 0.2, the historical priority permission comprehensive value of terminal A is 3, the historical priority permission comprehensive value of terminal B is 2.4, and the historical priority permission comprehensive value of terminal C is 1.6. The first characteristic information obtained by sorting by value is: terminal A>terminal B>terminal C. For example, terminal A was displayed 10 times in the past month, with an average memory occupancy of 20% of the smart screen; terminal B was displayed 8 times, with an average memory occupancy of 15%; terminal C was displayed 6 times, with an average memory occupancy of 10%. The historical comprehensive value of no priority permissions for terminal A is 14, the historical comprehensive value of no priority permissions for terminal B is 10.8, and the historical comprehensive value of no priority permissions for terminal C is 7.6. The second characteristic information obtained by sorting by value size is: terminal A>terminal B>terminal C.

[0087] Step 2: During the first cycle of the smart screen display, each terminal sends a display request to the edge computing node. The edge computing node determines the display request of each terminal based on the received display request and feeds back the corresponding determination result. Each terminal collaboratively and interactively displays on the smart screen based on the determination result.

[0088] The process of judging the display request of each terminal is as follows:

[0089] The edge computing node extracts the current display request priority level of each terminal from the display request, and releases the corresponding display request in order of priority level. At the same time, it monitors the memory usage of the smart screen and compares it with the preset security threshold. If the preset security threshold is reached, the release of the display request is suspended.

[0090] Within the preset security threshold, if the priority authority levels are the same, the first feature information of the corresponding terminal is retrieved, and the historical priority authority comprehensive values of the corresponding terminals are compared, and the display request of the terminal with the higher historical priority authority comprehensive value is preferentially approved;

[0091] Within the preset security threshold, if the terminal has not set the priority permission level for the current display request, the second feature information of the corresponding terminal is retrieved, and the historical comprehensive value of no priority permission of the corresponding terminal is compared, and the display request of the terminal with a higher historical comprehensive value of no priority permission is prioritized.

[0092] In this embodiment, it should be noted that based on the display requests sent by each terminal, according to the established arbitration rules, taking into account factors such as priority level and memory usage, it is orderly determined which terminals' display requests can be released, ensuring that the display on the smart screen is orderly, avoiding display conflicts, improving display efficiency, and realizing the orderly integrated display of information between multiple terminals, thereby enhancing the interactivity and practicality of the entire system. As an example, the priority level of the current display request of each terminal is first extracted. Assuming that the priority level of terminal A's request is 1, and terminals B and C have not set priority levels, the edge computing node makes an arbitration based on the priority level, giving priority to terminal A's display request, and monitoring the memory usage of the smart screen at the same time. Assuming that the current memory usage is 30% and the preset security threshold is 80%, if it does not reach the threshold, the arbitration continues. For terminals B and C, if they are within the threshold, terminals B and C need to compare the corresponding feature information. Based on the second feature information calculated previously (terminal B>terminal C), the display request of terminal B is then released, and the memory usage of the smart screen is monitored at the same time. If it does not reach the threshold, the display request of terminal C is then released.

[0093] Step 3: After the smart screen completes the first cycle of display, it updates the historical information features. In the second cycle, it re-determines the display requests of each terminal and feeds back the corresponding determination results. Each terminal will collaboratively and interactively display on the smart screen based on the determination results.

[0094] The process of updating historical information features is as follows:

[0095] The information on the display status of the smart screen in the first cycle and the corresponding display information of each terminal are used as historical data to re-obtain historical information features.

[0096] In this embodiment, it should be noted that by updating historical data, the feature information can be continuously and automatically updated to ensure that the feature information can better reflect the priority release sequence of different terminals and achieve dynamic optimization and adjustment of the displayed content.
