[0075] For the purpose, technical solutions and advantages of the present application to be clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0076] The technical solutions of the embodiments of the present application and the technical effects produced by the technical solutions of the present application will be described below through the description of several exemplary embodiments. It should be pointed out that the following embodiments can be mutually referenced, borrowed or combined, and the same terms, similar features and similar implementation steps in different embodiments will not be described repeatedly.

[0077] Figure 1 A flowchart of a device control method provided by the embodiments of the present application is shown in FIG. 1, which is taken as an example that the method is applied to a first terminal. The method comprises the following steps. Figure 1

[0078] In step S101, an operation instruction of a user for a first image acquisition device in at least two image acquisition devices of a vehicle is received.

[0079] Specifically, a plurality of hardware devices can be carried on the first vehicle, including but not limited to the first terminal and the at least two image acquisition devices. The first terminal can be a vehicle terminal or a user terminal. The user terminal can include a smart phone, a tablet computer, a notebook computer, a smart voice interaction device (such as a smart speaker) or a wearable electronic device (such as a smart watch) and the like.

[0080] ​The image acquisition device can be a camera. The image acquisition device can be loaded on the vehicle, for example, four cameras can be externally arranged in the front, rear, left and right directions of the vehicle. The image acquisition device can also be loaded on the vehicle-mounted unmanned aerial vehicle. The vehicle-mounted unmanned aerial vehicle refers to an unmanned aerial vehicle carried on the vehicle, for example, carried on the roof of the vehicle. Since the unmanned aerial vehicle can leave the vehicle and fly to an area at a certain distance from the vehicle, the image acquisition device carried on the unmanned aerial vehicle can capture a larger range of areas.

[0081] The at least two image acquisition devices can be all carried on the vehicle, all carried on the unmanned aerial vehicle, or partially carried on the vehicle and partially carried on the unmanned aerial vehicle. The number of image acquisition devices and the specific mounting manner are not limited in the embodiments of the present application.

[0082] The first terminal receives an operation instruction input by the user for the first image device. The first image device can be determined by the user from the at least two image acquisition devices of the vehicle and needs to be controlled. The first image device can be one or multiple, and the number of the first image device is not limited in the embodiments of the present application.

[0083] The first terminal can be installed with an APP (Application) providing a device control function. The user can interact with the APP on the first terminal. The operation instruction received by the first terminal can be input by the user through an interactive control in the APP. The interactive control can be a voice interactive control or a text interactive control. The input mode of the operation instruction is not limited in the embodiments of the present application.

[0084] In step S102, a first function file matched with the operation instruction is determined from the plurality of function files encapsulated, in response to the operation instruction. The function file is encapsulated in the first terminal by a software development kit (SDK).

[0085] Specifically, the operation instruction can not only include which devices need to be controlled, but also include which functions need to be executed by each device.

[0086] According to the operation instruction, the target function that the user needs to control the first image acquisition device to execute can be determined, and then the function file corresponding to the target function is determined from the plurality of function files encapsulated in the first terminal as the first function file matched with the operation instruction.

[0087] The first function file can be one or multiple. One first image acquisition device can correspond to one first function file or multiple first function files, and the present application does not limit this.

[0088] The function file can be a file corresponding to a function of controlling the image acquisition device to perform a certain function, and each function file can correspond to one function. For example, a live broadcast function file can be set for a live broadcast function of the image acquisition device, and a video recording function file can be set for a video recording function of the image acquisition device.

[0089] For different types of image acquisition devices, such as different models of image acquisition devices or image acquisition devices from different manufacturers, the implementation methods of the different types of image acquisition devices for the same function can be packaged through a software development kit (SDK), a corresponding function file is generated, and the function file is preloaded into the first terminal.

[0090] Each function file includes an implementation method of different types of image acquisition devices for a function, that is, the same function file can be used to control different types of image acquisition devices to implement the corresponding function, and multiple function files are preloaded on the side of the first terminal. Therefore, it is not necessary to design a corresponding interface for each type of image acquisition device to call the SDK built in the image acquisition device. In particular, when the image acquisition device mounted on the vehicle is changed, for example, when the image acquisition device A is replaced by the image acquisition device B, or when the image acquisition device C is added, it is not necessary to recompile the code for the changed image acquisition device, which greatly reduces the development cost and improves the scalability of the method.

[0091] In addition, the device control method provided by the embodiment of the present application is not limited by the type of the image acquisition device mounted on the vehicle, so the method applied to the first vehicle can be reused on the second vehicle, further reducing the development cost and improving the reusability of the method.

[0092] In step S103, the function corresponding to the first function file is called to control the first image acquisition device through the local area network.

[0093] Specifically, each function file records a method for implementing the corresponding function, and each method can be represented in the form of a function. After determining the first function file matched with the operation instruction, the function corresponding to the first function file can be called to control the first image acquisition device to perform the corresponding function through the function.

[0094] The first terminal and the first image acquisition device can be connected to the same local area network, and the first terminal can communicate with the first image acquisition device through the local area network by Wi-Fi (wireless network communication technology). The first terminal and the first image acquisition device can be configured with corresponding communication modules, such as network cards.

[0095] It should be noted that the first terminal and the first image acquisition device are in the same local area network, that is, in the same network segment, so even if the first image acquisition device is in a shutdown state, the first image acquisition device can be started through Wi-Fi communication.

[0096] The local area network connected with the first terminal and the first image acquisition device can be established based on at least one vehicle-mounted router, the at least one vehicle-mounted router can be carried on the same vehicle or different vehicles, and can be carried on the first vehicle or other vehicles except the first vehicle. When the number of vehicle-mounted routers is at least two, the mesh function or the bridge function of each of the at least two routers can be enabled to form a local area network.

[0097] Compared with the prior art in which the devices on the vehicle communicate through the LTE (Long Term Evolution) mobile network, in some remote areas with poor mobile network signals, such as mountainous areas or uninhabited areas, or even areas without network, the devices cannot communicate with each other or the communication quality is poor. In the embodiment of the application, the local area network is established through the at least one vehicle-mounted router, so the first terminal and the first image acquisition device can communicate through the local area network only when they are in the area covered by the local area network, and do not need to rely on the mobile network for communication, and thus are not affected by the quality of the mobile network signal, and can be applied to remote areas with poor mobile network signals, thereby improving the application range of the method.

[0098] The method provided in the embodiment of the application encapsulates a plurality of function files through an SDK, and preconfigures the plurality of function files in the first terminal, so that the same function file can be used to control different types of image acquisition devices to implement corresponding functions. When the image acquisition device carried on the vehicle is changed, the code for the changed image acquisition device does not need to be re-written, thereby greatly reducing the development cost and improving the scalability of the method; and the method is not limited by the types of image acquisition devices carried on the vehicle, and can be reused on different vehicles.

[0099] In addition, the local area network is established through the at least one vehicle-mounted router, and the first terminal and the first image acquisition device communicate through the local area network, so the first terminal and the first image acquisition device do not need to rely on the mobile network for communication, and thus are not affected by the quality of the mobile network signal, and can be applied to remote areas with poor mobile network signals, thereby improving the application range of the method.

After the image acquisition device is powered on, the first terminal can perform subsequent control operations on the first image acquisition device through the Socket communication.

For example, when the first terminal finds that the available storage space of the storage card of the first image collection device is reduced, the first terminal can obtain the changed available storage space of the storage card of the first image collection device, and when the available storage space of the storage card is less than a preset threshold, the first terminal can send a reminder message of "insufficient available storage space" to the user.
