[0064] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention.

[0065] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0066] In the description of the present application, it should be noted that if terms such as "upper", "lower", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of this application is normally placed, it is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0067] In addition, the terms "first", "second", etc. in the description, claims and above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0068] It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other.

[0069] With the rapid development of science and technology, there are more and more various management devices. A board card can be installed on the management device, and the control of the display device can be achieved through the board card on the management device.

[0070] In the related art, different board card manufacturers have different control methods for the same control function. If a target control instruction is received, it is necessary to determine the installed target board card, and then determine the target control method of the target board card for the target control instruction. The target board card controls the display device according to the target control method. Among them, because different board card manufacturers have different system call methods, when a new function is added to the target board card, the board card manufacturer needs to re-sign the target board card before it can call the system interface through the target board card, and then a new control function can be added to the target board card.

[0071] For example, different board card manufacturers have different API (Application Programming Interface) signatures and API module definitions for different control functions. By way of example, for the screenshot function, the instruction of manufacturer A is: ScreenShotManager.sreenshot(); the instruction of manufacturer B is: SurfaceControl.screenshot(int width, int height); when adding a new control function, it is necessary to interface with the board card manufacturer for the required function, and the process is cumbersome. Moreover, when interfacing with a new manufacturer for existing functions, it is also necessary to re-interface and test.

[0072] In addition, if the process of adding the signature of the board manufacturer is not added, any ordinary application can call the system API, which will include some risky APIs, such as restarting the device, silently installing applications, uninstalling applications, etc., increasing system risks. Therefore, this solution also has significant drawbacks.

[0073] In order to solve the problem in related technologies that when adding a new control function for a target board on a management device, it is necessary to manually connect with the corresponding board manufacturer, and the process is relatively cumbersome. An embodiment of the present application provides a device control method. The management device installed with the target board receives the function file package sent by the terminal device through the update package management program and the shell application program, and can realize the automatic update of the control function according to the function file package. When performing function update, it is not necessary for the board manufacturer to sign again, making the update of the control function more convenient and improving the efficiency of the control function update.

The display device 101 and the management device 102 are communicatively connected, and the terminal device 103 and the management device 102 are also communicatively connected.

[0076] In practical applications, the terminal device 103 can remotely control the function of the display device 101 through the target board 1011 in the management device 102, and obtain the function control result for the display device 101, and can realize remote monitoring and control of the display device 101. The function control may include at least one of the following: screenshot, screen recording, restarting the device, installing applications, etc.

[0077] In the embodiment of the present application, the terminal device 103 can send a call request to the management device 102, the management device 102 can receive the call request, and the management device 102 can use the shell application program to control the display device 101 to execute the corresponding function according to the call request to obtain the function control result; the display device 101 feeds back the function control result to the terminal device 103 through the management device 102.

[0078] In some embodiments, the terminal device 103 may send a function file package to the management device 102. The management device 102 receives the function file package sent by the terminal device 103 through the update package management program, and updates the initial function file package in the shell application running on the target board 1011 according to the function file package, so that the management device 102 has the control function corresponding to the function file package, and the control function is the function of controlling the display device 101.

[0083] It should be noted that the shell application running in the target board is the shell application signed by the board manufacturer, not an empty shell application. Among them, when the shell application is the shell application signed by the board manufacturer, the shell application can call the system permission of the display device.

[0084] In the embodiments of the present application, the management device can be used as the controller of the display device, and the system permission of the display device can also be regarded as the system permission of the management device, that is, the shell application can call the system permission of the display device, and it can also be considered that the shell application can call the system permission of the display device.

Updating the functions of the target board can also be understood as updating the functions of the shell application program.

[0090] It should be noted that the terminal device can remotely control the functions of the display device through the management device, and the functions that can be controlled include: the control functions corresponding to the function file package.

If the version number in the newly received function file package is higher than the version number in the initial function file package, replace the initial function file package under the shell application program system folder with the newly received function file package in the update package management program, and dynamically uninstall the initial function file package.
