[0028] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] With the advent of the information age, the rapid development of computer multimedia technology and the widespread application of network technology have led to a growing demand for large-screen, multi-color, high-brightness, and high-resolution displays, from command and control centers and network management centers to impromptu meetings, technical seminars, and outdoor advertising. Traditional CRT monitors struggle to meet these demands. To meet this societal need, the development of smart large-screen displays has received significant attention from manufacturers in recent years. Smart large-screen technology has rapidly advanced, and its application scenarios have further expanded. The applications installed on smart large-screen displays are adapted to different scenarios, and technological advancements have enabled a wide range of applications to meet diverse needs. When a smart large-screen displays are equipped with multiple applications, user management becomes essential. This management inevitably involves deleting applications, and inadvertent deletions are unavoidable. With existing technology, finding and restoring deleted applications requires manual effort, searching for the deleted application, locating the backup location, and then manually installing and restoring it.

[0030] For example, when manually recovering a deleted application, one must first manually determine which files were deleted and the names of the deleted files, then insert a mobile storage device such as a USB flash drive that stores the application installation package files, and search for the required installation package files one by one. If the inserted mobile storage device does not have the corresponding installation package file, a new mobile storage device must be reinserted and searched again one by one until the corresponding installation package file is found. Then, one must manually determine one by one whether the installation package files actually exist and are available, and then install them. This is very time-consuming and labor-intensive.

[0031] To address the problems of manually searching and installing deleted applications in the prior art, this embodiment provides a method for automatically restoring backup applications. The method can monitor system application deletion commands based on a pre-created background service and record basic information about the deleted applications, including package name, application name, and number of deletions. When the system needs to restore the deleted applications, the system automatically retrieves the basic information (package name, application name) of the top three applications with the least number of deletions, automatically obtains the installation packages of the corresponding applications from an inserted mobile storage device, automatically determines whether the installation package files are actually available, and displays the information of the available installation packages on the screen in a list for the user to select and install. The system automatically monitors the user's selection of applications to be restored and stores the selected applications in a linked list. The system also automatically monitors the user's click on the restore installation button and installs the application files selected by the user. Alternatively, if the user clicks restore installation without selecting an application in the linked list, the system automatically installs the top three applications with the least number of deletions stored in the memory and displays the names of the installed applications on the screen, informing the user of the final installation results. This avoids the tedious and inconvenient process of manually searching for deleted files, making judgments, and performing installation.

[0032] Exemplary Methods

[0033] The method for automatically restoring a backup application in this embodiment can be applied to a terminal device. Figure 1 As shown in , the method for automatically restoring a backup application includes the following steps:

[0034] Step S100: The system creates a background service to monitor the system's command to delete an application, record basic information of the deleted application, and save it to the first memory.

[0035] To enable the smart large-screen system to automatically restore the backup application of deleted applications, in this embodiment, the smart large-screen system first needs to create a background service to monitor the system's daily command to delete applications. The background service also needs to record and store the basic information of the deleted applications. The stored basic information includes the package name of the deleted application, the application name, and the total number of times the application has been deleted. This basic information is stored in the first memory. For ease of management and retrieval, the basic information of the deleted applications is stored in ascending order according to the number of times the application has been deleted.

[0036] Step S200: The system detects a request to start an application, selects three pieces of information with the least number of deletions from the first memory, and saves them to the second memory.

[0037] In this embodiment, the background service created by the smart large screen system detects the request of the smart large screen system to start an application. If it is found that the application required to be started does not exist in the system, the system immediately starts the program to automatically search for deleted applications to search for the application.

[0038] The smart large-screen system selects the first three application information with the least number of deletions in the first memory and saves them in the second memory. The content of the application information stored in the second memory includes: the package name and application name of the application.

[0039] Step S300: After the system automatically searches for the deleted application, it reads the basic information of the installation package in the specified directory of the external storage device and saves it to the third memory.

[0040] Specific implementation methods are as follows Figure 2 As shown in , step S300 specifically includes the following steps:

[0041] Step S301: The system obtains an identifier of the second storage device. When the identifier is equal to 1, the system starts a backup application recovery.

[0042] Specifically, in this embodiment, the smart large-screen system obtains the identifier of the second memory. The identifier 1 of the second memory means that the smart large-screen system starts the program to automatically search for deleted applications. The task of searching for information on the application with the least number of deletions has been completed. The smart large-screen system can start the next step, that is, start to restore the installation program of the deleted application.

[0043] Step S302: The system monitors the connection status of the external storage device;

[0044] Specifically, in this embodiment, the smart large-screen system monitors by a background service whether an external mobile storage device is connected to the large-screen system, that is, whether an external mobile storage device such as a USB flash drive or a mobile hard disk has been connected to the smart large-screen system.

[0045] Step S303: The system detects that no external storage device is connected, prompts that there is no external storage device, and ends the automatic recovery backup application.

[0046] Specifically, in this embodiment, the background service of the smart large-screen system detects that no external storage device is connected, that is, no external storage device such as a USB flash drive or a mobile hard disk is connected to the smart large-screen system. The smart large-screen system prompts the user that there is no external storage device connected to the system, that is, there is no installation file that can be used to select the application to be restored and installed. The smart large-screen system automatically restores the backup application and the program ends on its own.

[0047] Step S304: The system monitors that an external storage device is connected, and the system reads basic information of the installation package of the backup application in the specified directory of the external storage device and saves it to the third memory.

[0048] Specifically, in this embodiment, the background service of the smart large-screen system monitors that an external storage device is connected, that is, an external storage device such as a USB flash drive or a mobile hard disk is connected to the smart large-screen system. The smart large-screen system reads the basic information of the installation package of the backup application stored in the specified directory (BACKUP_DIR) by the external storage device such as the USB flash drive or the mobile hard disk, including the package name of the application and the application name, and saves it to the third memory.

[0049] Step S400: The system determines whether the information of the installation package is empty, and displays the information of the available installation packages on the screen in a list.

[0050] Specific implementation methods are as follows Figure 3 As shown in , step S400 specifically includes the following steps:

[0051] Step S401: The system obtains basic information of the installation package of each backup application in the third memory, and the system determines whether the basic information of the installation package of each backup application is empty.

[0052] Specifically, in this embodiment, the smart large-screen system reads the basic information of the installation package of the backup application stored in the designated directory (BACKUP_DIR) by an external storage device such as a USB flash drive or a mobile hard disk, including the package name of the application and the application name, and saves it to the third memory. The smart large-screen system obtains the basic information of the installation package of each backup application in the third memory, and analyzes and judges the basic information of the installation package of each backup application to determine whether the file of the application installation package actually exists and is available.

[0053] Step S402: If the system determines that the information of the installation package of the backup application is empty, the system prompts that the external storage device does not have the backup application and ends the automatic restoration of the backup application.

[0054] Specifically, in this embodiment, the smart large-screen system obtains basic information about each backup application installation package in the third memory, analyzes and determines the basic information about each backup application installation package, and determines that the file of the application installation package does not exist or is unavailable. The smart large-screen system notifies the user that the file of the application installation package does not exist or is unavailable, i.e., there is no installation file for the application to be restored, and the smart large-screen system automatically terminates the process of restoring the backup application.

[0055] Step S403: If the system determines that the basic information of the backup application installation package is not empty, the system obtains the basic information of the backup application installation package and displays the basic information of the backup application installation package on the screen in a list.

[0056] Specifically, in this embodiment, the smart large-screen system obtains basic information about each backup application installation package in the third memory, analyzes and determines the basic information of each backup application installation package, and determines whether the application installation package file actually exists and is available. The smart large-screen system obtains basic information about each backup application installation package and displays the basic information on the screen using a list (ListView), providing it to the user for installation selection.

[0057] Step S500: The system monitors the user's selection of applications to be restored and stores the selected applications in a linked list.

[0058] Specifically, in this embodiment, the smart large-screen system obtains the basic information of the installation package of each backup application, and displays the basic information of the installation package of the backup application on the screen using a list (ListView). The background service of the smart large-screen system monitors the user's selection of the application that needs to be restored and installed according to the list (ListView), and stores the selected application in a linked list.

[0059] Step S600: The system monitors the user clicking the restore installation button and installs the application;

[0060] Specific implementation methods are as follows Figure 4 As shown in , step S600 specifically includes the following steps:

[0061] Step S601: The system determines whether the user's selection is empty;

[0062] In this embodiment, the background service of the smart large-screen system listens for the user clicking the restore installation button, and monitors whether the user has selected the application that needs to be restored and installed when clicking the restore installation button.

[0063] Step S602: The system determines that the user's selection is empty, and the system prompts the user that he has not selected the application to be restored and installed. The system automatically reads the package name and application name of the application in the second memory, installs the application, and saves the package name and application name of the application to the third memory.

[0064] Specifically, in this embodiment, when the background service of the smart large-screen system detects that the user has not selected an application to be restored when clicking the restore installation button, the smart large-screen system prompts the user that the application has not been selected for restoration, and automatically reads the information of the first three applications with the least number of deletions stored in the second memory, including the application package name and application name, and installs the application by obtaining the installation package file stored in an external storage device such as a USB flash drive or mobile hard disk connected to the system. After the installation is complete, the package name and application name of the automatically installed application are saved to the third memory.

[0065] Step S603: The system determines that the user's selection is not empty, and the system installs the application according to the package name and application name of the application selected by the user, and saves the package name and application name of the application to the fourth memory.

[0066] Specifically, in this embodiment, the smart large-screen system background service monitors when a user clicks the restore installation button and selects an application to be restored. The smart large-screen system automatically searches for the corresponding installation package file for the application in an external storage device such as a USB flash drive or mobile hard drive connected to the system, based on the package name and application name of the application selected by the user, and then installs the application. After the installation is complete, the system automatically saves the package name and application name of the application selected by the user to the fourth memory.

[0067] Step S700: The system displays the result of automatically restoring the backup application on the screen.

[0068] Specific implementation methods are as follows Figure 5 As shown in , step S400 specifically includes the following steps:

[0069] Step S701: The system obtains the identifiers of the third storage and the fourth storage, which indicates that the system's application recovery and backup operation is completed.

[0070] Specifically, in this embodiment, when the smart large-screen system performs automatic backup and recovery, the system automatically completes the recovery of the deleted application, and the recovery result is displayed by the smart large-screen system judging the identification of the third memory and the fourth memory.

[0071] If the identifier of the third memory or the fourth memory is displayed as identifier 1, it indicates that the smart large-screen system has completed the backup application restoration action. If the smart large-screen system obtains identifier 1 for the third memory, it means that the user did not choose to install the application, and the backup application was automatically restored by the system. If the smart large-screen system obtains identifier 1 for the fourth memory, it means that the user selected the application to be installed through a list. Displaying the installed backup application on the screen is to inform the user of the result of restoring the application.

[0072] Step S702: When the identifier of the third memory obtained by the system indicates that the system has completed restoring the backup application, the system displays the name of the backup application automatically restored by the system on the screen;

[0073] Step S703: When the system obtains the identifier of the fourth memory indicating that the system restores the backup application action is complete, the system displays the name of the backup application selected by the user for restoration on the screen.

[0074] Exemplary devices

[0075] like Figure 6 As shown in , an embodiment of the present invention provides a device for automatically restoring a backup application, the device comprising:

[0076] The automatic search module 10 for deleted applications is used to monitor the system's command to delete applications, record basic information of the deleted applications, and save it to the memory.

[0077] Specifically, the automatic search for deleted applications module 10 mainly completes the following work process: first, a background service is created in the smart large screen system to listen to the command of deleting applications from the smart large screen system, and record the basic information of the deleted applications (package name, application name and the number of times the application has been deleted) and save it to the first memory;

[0078] The background service detects the smart large screen system's request to start an application. If the application does not exist, the smart large screen system starts the automatic search for deleted applications function, selects the three pieces of information with the least number of deletions in the first memory, and saves them to the second memory.

[0079] The backup application recovery module 20 is used to recover the application needed by the user that has been deleted by the system.

[0080] Specifically, after the smart large-screen system automatically searches for the deleted application, it determines whether the large-screen system is connected to an external storage device such as a USB flash drive or a mobile hard drive. If an external storage device such as a USB flash drive or a mobile hard drive is connected, the smart large-screen system obtains the basic information of the installation package in the specified directory of the external storage device such as the USB flash drive or the mobile hard drive, and saves it to the third memory.

[0081] Then, the smart large screen system determines whether the information of the installation package obtained from the external storage device such as the USB flash drive or mobile hard disk is real and available, and displays the information of the available installation packages on the screen in a list (ListView) for selection;

[0082] The background service monitors the applications that need to be restored and installed selected by the user, and stores the applications that need to be restored and installed selected by the user in a linked list;

[0083] The background service continues to listen for the user to click the restore installation button, and obtains whether the user selects the application information to be installed when clicking the restore installation button. If no selection is made, the system automatically installs the application according to the package name and application name of the application stored in the second memory; if the user selects the application information to be installed when clicking the restore installation button, the system installs the application according to the application selected by the user.

[0084] The application recovery display module 30 is used to display the name of the application restored by the system on the screen.

[0085] Specifically, the application recovery display module 30 determines whether to display the installation result by obtaining the identifiers of the third memory and the fourth memory, wherein the identifier 1 indicates that the system's recovery backup application action is completed;

[0086] The smart large-screen system obtains the identifier 1 of the third memory, which represents the backup application automatically restored by the system, and the system displays the name of the backup application automatically restored by the system on the screen;

[0087] The smart large-screen system obtains the identifier 1 of the fourth memory, which represents the backup application selected by the user to be restored. The system displays the name of the backup application selected by the user to be restored on the screen.
