[0029] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0031] In the following description, references to “some embodiments,” “this embodiment,” “embodiments of the present application,” and examples, etc., describe a subset of all possible embodiments. However, it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

[0032] If similar descriptions of "first / second" appear in the application documents, the following explanation is added. In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0033] In the embodiment of the present application, the term "and / or" is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, object A and / or object B may represent three situations: object A exists alone, object A and object B exist at the same time, and object B exists alone.

[0034] Small civilian controlled terminals are now widely used across various industries. Aerial photography controlled terminals are increasingly becoming a popular choice, finding applications in areas such as aerial photography, resource exploration, news reporting, tourism promotion, and digital development. However, during their use, controlled terminals are often subject to unexpected events such as mid-air collisions, battery failure, and power depletion. These can cause the controlled terminal to drop to the ground after losing its signal, putting it at risk of being lost. Once the signal is lost, the longer it persists, the more difficult it becomes to recover, and the lower the probability of recovery. Therefore, effective measures to quickly recover the controlled terminal are crucial.

[0035] At present, although the existing technology can obtain the GPS positioning coordinates of the controlled terminal before the signal is lost, it is necessary to download a third-party navigation system and copy the GPS coordinate data into the third-party navigation system to realize path planning and search. This will make the process cumbersome, not only time-consuming, but also increase the difficulty of retrieving the controlled terminal.

[0036] It should be noted that the controlled terminal can be an electronic device such as a drone, a robot, or a terminal, and this application does not impose any restrictions on this.

[0037] Based on this, an embodiment of the present application provides a method for searching a controlled terminal, which is applied to a vehicle-mounted terminal, wherein the vehicle-mounted terminal has a display screen and is set in a vehicle. Figure 1 A schematic diagram of an optional application scenario provided in an embodiment of the present application, such as Figure 1As shown, this application scenario 10 includes a vehicle 11, a remote control device 12 for a controlled terminal, and a controlled terminal 13. Vehicle 11 and remote control device 12 are connected via short-range wireless communication technology, and vehicle 11 is equipped with an onboard terminal with a display screen. Once a connection is established between controlled terminal 13 and remote control device 12, and if controlled terminal 13 is lost, the onboard terminal can be used to track controlled terminal 13. Remote control device 12 is also referred to as a remote control terminal.

[0038] In the embodiment of the present application, the controlled terminal 13 may be a drone.

[0039] Specifically, first, the vehicle terminal displays a navigation system interface in response to a navigation setting instruction, wherein the navigation setting instruction is used to use the vehicle terminal to search for a controlled terminal that is in a lost state. Then, when the vehicle terminal establishes a connection with the remote control terminal of the controlled terminal and the controlled terminal is in a lost state, in response to a triggering operation on the controlled terminal tracking control, route guidance information for the vehicle terminal and the controlled terminal is displayed on the navigation system interface. In this way, when the vehicle terminal establishes a connection with the remote control terminal of the controlled terminal and the controlled terminal is in a lost state, a one-touch navigation operation is implemented through the controlled terminal tracking control on the navigation system interface of the vehicle terminal, and route guidance information of the optimal path between the vehicle terminal and the controlled terminal is displayed on the navigation system interface. The route guidance information is determined based on second position information obtained by coordinate conversion processing of the first position information of the controlled terminal, and the coordinate conversion processing is used to adapt the coordinate format between the second position information and the current position information of the vehicle terminal, thereby assisting the vehicle owner to find the lost controlled terminal along the route planned by the navigation immediately, thereby greatly shortening the time of searching for the controlled terminal. Compared to traditional search methods, the embodiments of the present application can simplify the search process for controlled terminals, improve the efficiency of finding controlled terminals, and thus reduce the difficulty of finding controlled terminals. In addition, by performing coordinate conversion processing on the first location information of the controlled terminal to obtain the second location information, it is possible to ensure that the coordinate format of the second location information is compatible with the current location information of the vehicle-mounted terminal, thereby improving the accuracy of route planning and the efficiency of finding controlled terminals.

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0041] Figure 2 A schematic diagram of a process for searching a controlled terminal provided in an embodiment of the present application Figure 1 ,like Figure 2 As shown, including S101 to S102:

[0042] S101. Displaying a navigation system interface in response to a navigation setting instruction; wherein the navigation setting instruction is used to use the vehicle-mounted terminal to find a controlled terminal in a lost state.

[0043] In an embodiment of the present application, the vehicle-mounted terminal presents a navigation system interface on the display interface in response to the navigation setting instruction.

[0044] In an embodiment of the present application, the navigation setting instruction is used to use the vehicle-mounted terminal to find a controlled terminal that is in a lost state. In other words, when the controlled terminal is in a lost state, the display interface of the vehicle-mounted terminal can be triggered to display the navigation system interface, and relevant personnel can operate the navigation system interface to find the controlled terminal.

[0045] In an embodiment of the present application, the display interface of the vehicle terminal may display multiple applications, such as icons or controls related to a navigation system, an entertainment system, a phone system, a music system, and a weather system. The vehicle terminal presents the navigation system interface on the display interface in response to a navigation setting instruction applied to the navigation system control.

[0046] In the embodiment of the present application, the navigation setting instruction can be an interaction method such as clicking, double-clicking, touching, long pressing, preset gestures, remote control, etc., and the embodiment of the present application does not impose any restrictions on this.

[0047] In the embodiment of the present application, the shape of the display area of ​​the navigation system interface can be a rectangle, square, diamond, trapezoid, rounded rectangle or clipped rectangle, etc. The embodiment of the present application does not limit the shape, size and specific position of the display area of ​​the navigation system interface.

[0048] In an embodiment of the present application, the navigation system interface may also be presented on the display screen in the form of a floating window, a shorthand window, etc. The embodiment of the present application does not impose any limitation on the presentation method of the data query interface.

[0049] In an embodiment of the present application, the navigation system interface can be presented in the form of a floating window. For example, the icon of the navigation system interface is displayed on the display interface of the vehicle terminal. By clicking the icon, the navigation system interface can be expanded. By clicking the zoom control in the navigation system interface terminal, the interface can be retracted into the form of an icon or a small window, which makes it convenient for users to view other applications.

[0050] S102. When a connection is established between the vehicle-mounted terminal and the remote control terminal of the controlled terminal, and the controlled terminal is in a lost state, in response to a trigger operation acting on the tracking control of the controlled terminal, route guidance information of the vehicle-mounted terminal and the controlled terminal is displayed in the navigation system interface; wherein the route guidance information is determined based on second position information obtained by coordinate conversion processing of the first position information of the controlled terminal, and the coordinate conversion processing is used to adapt the coordinate format between the second position information and the current position information of the vehicle-mounted terminal.

[0051] In an embodiment of the present application, when a connection is established between the vehicle-mounted terminal and the remote control terminal of the controlled terminal and the controlled terminal is in a lost state, the vehicle-mounted terminal responds to a trigger operation acting on the tracking control of the controlled terminal, performs route planning, and displays the route guidance information of the vehicle-mounted terminal and the controlled terminal in the navigation system interface.

[0052] In the embodiment of the present application, the vehicle terminal and the remote control terminal of the controlled terminal are connected via short-range wireless communication technology. For example, the vehicle terminal and the remote control terminal can be connected via Bluetooth, NFC, etc.

[0053] In the embodiment of the present application, the route guidance information is determined based on the location information sent by the controlled terminal to the remote control terminal.

[0054] In an embodiment of the present application, a positioning module, such as a GPS (Global Positioning System) positioning module, is provided in the controlled terminal. The positioning module is used to record the location, altitude, speed, and other information of the controlled terminal in real time and send the data in real time to the remote control device or ground terminal device of the controlled terminal. The data includes the GPS coordinate data of the controlled terminal. It should be noted that the remote control device or ground terminal device of the controlled terminal is the remote control terminal.

[0055] In the embodiment of the present application, the controlled terminal may be a drone, a robot, etc., and the embodiment of the present application does not impose any limitation on this.

[0056] In an embodiment of the present application, the prerequisites for displaying the route guidance information of the vehicle terminal and the controlled terminal in the navigation system interface include: the vehicle terminal and the remote control terminal need to establish a connection, and confirm that the controlled terminal is in a lost state.

[0057] In an embodiment of the present application, the route guidance information is used to indicate the optimal route between the current location of the vehicle and the lost location of the controlled terminal.

[0058] In an embodiment of the present application, the route guidance information may also include: information on preset landmark locations along the way, such as iconic buildings, natural attractions, etc., to facilitate users to determine the route according to the landmarks along the way.

[0059] In an embodiment of the present application, when the vehicle is moving forward according to the route guidance information, the user can be notified of the direction of travel through voice broadcast, and the user can be further reminded when the vehicle is about to reach the location marked along the way. In addition, when the vehicle is about to reach the destination (the lost location of the controlled terminal), the user is reminded through voice broadcast that the vehicle has arrived and exits the navigation.

[0060] In an embodiment of the present application, when the route guidance information of the vehicle terminal and the controlled terminal is displayed in the navigation system interface, the vehicle terminal responds to the triggering operation of the window reduction control acting on the navigation system interface, and presents the navigation system interface in the form of a small floating window on the display interface, so that the user can view other system applications, such as music system, entertainment system, etc.

[0061] In an embodiment of the present application, when the route guidance information of the vehicle terminal and the controlled terminal is displayed in the navigation system interface, the vehicle terminal can share the route guidance information with any electronic device connected to the vehicle terminal in response to the triggering operation of the route sharing control acting on the navigation system interface. Of course, the route guidance information can also be shared with multiple electronic devices connected to the vehicle terminal at the same time. It should be noted that the electronic device can establish a connection with the vehicle terminal through short-range wireless communication technology, and the electronic device can also establish a connection through the hardware interface of the vehicle terminal (such as a USB interface).

[0062] It is understandable that by sharing route guidance information with other electronic devices, other users can also quickly obtain the lost location information of the controlled terminal. In addition, if the network of the vehicle terminal is unstable, by sharing route guidance information with other electronic devices, it is possible to effectively avoid the situation where the navigation of the vehicle terminal is unstable when the network is unstable.

[0063] In some embodiments of the present application, the display content in the navigation system interface includes: the current location information of the vehicle, the second location information of the controlled terminal, and route guidance information.

[0064] It can be understood that by displaying the vehicle's current location information, the location information of the controlled terminal (i.e., the lost location) and route guidance information on the navigation system interface, the car owner can be assisted to find the lost controlled terminal along the navigation planned route as soon as possible, thereby greatly shortening the search time.

[0065] It can be understood that the vehicle-mounted terminal automatically imports the GPS coordinates of the controlled terminal into the navigation system through the vehicle-mounted terminal for processing and display, realizing automatic import and automatic processing, so that the vehicle-mounted terminal can reduce the user's time for path planning during the entire process of searching and finding the controlled terminal, thereby improving the efficiency of finding the body.

[0066] It's understandable that the vehicle-mounted terminal, through the establishment of an interconnected transmission system, connects the vehicle-side navigation system and the remote control terminal of the controlled terminal. The controlled terminal periodically transmits GPS coordinates to the vehicle navigation page, making data transmission and processing more convenient, further improving the efficiency of finding the body, and simplifying the search process of the controlled terminal.

[0067] In some embodiments of the present application, the method for finding a controlled terminal also includes: when the vehicle-mounted terminal determines that the controlled terminal is in a lost state, displaying a controlled terminal tracking pop-up window in the navigation system interface; the controlled terminal tracking pop-up window includes a controlled terminal tracking control.

[0068] In an embodiment of the present application, the vehicle-mounted terminal receives the location information of the controlled terminal sent by the remote control terminal of the controlled terminal in real time, and displays the location information of the controlled terminal in real time in the navigation system interface, wherein the location information of the controlled terminal is sent to the remote control terminal through the positioning module of the controlled terminal, that is, the role of the remote control terminal is to forward the location information of the controlled terminal to the vehicle-mounted terminal. Furthermore, when the vehicle-mounted terminal fails to receive the location information of the controlled terminal within a period of time, it can be determined that the controlled terminal is in a lost state at this time. At this time, the navigation system interface displays a controlled terminal tracking pop-up window, and the vehicle-mounted device responds to the triggering operation of the controlled terminal tracking control in the controlled terminal tracking pop-up window, and displays the route guidance information from the vehicle to the lost location of the controlled terminal in the navigation system interface.

[0069] For example, Figure 3 Schematic diagram of an optional navigation system interface provided in an embodiment of the present application Figure 1 ,like Figure 3 As shown, the vehicle-mounted terminal receives the location information of the controlled terminal (i.e., the current location of the controlled terminal) sent by the remote control terminal of the controlled terminal in real time, and displays the current location of the controlled terminal, the current location of the vehicle, and the distance information between the two in real time in the navigation system interface. In addition, the navigation system interface can also include multiple function controls, such as sharing controls, opening connection controls, disconnection controls, setting controls, closing window controls, shrinking window controls, etc. Currently, other function controls can also be included in specific application scenarios. Here are just some examples, and this application does not impose any restrictions on this.

[0070] Here Figure 3Take the function controls displayed in the navigation system interface shown as an example, where the share control is used to share route guidance information to at least one electronic device connected to the vehicle-mounted device; the open connection control is used to instruct the vehicle-mounted device to establish a connection with the remote control terminal of the controlled terminal (usually through short-range wireless communication technology); the disconnect control is used to instruct the vehicle-mounted device to disconnect from the remote control terminal of the controlled terminal; the setting control is used to perform some other general settings on the vehicle-mounted terminal, the controlled terminal or the remote control terminal; the close window control is used to instruct the vehicle-mounted terminal to stop navigation and close the window; the shrink window control is used to instruct the vehicle-mounted terminal to present the navigation system interface in the display interface as a small floating window.

[0071] For example, Figure 4 As shown, the vehicle terminal responds to the trigger operation of the shrink window control and presents the navigation system interface in the form of a small floating window on the display interface. In this way, the user can view other system applications, such as the music system, while navigating, thereby improving the user experience.

[0072] Furthermore, when the vehicle terminal fails to receive the location information of the controlled terminal within a period of time, it can be determined that the controlled terminal is in a lost state. At this time, the navigation system interface displays a pop-up window for tracking the controlled terminal. Figure 5 As shown, a prompt message can be displayed in the controlled terminal tracking pop-up window, which is used to remind the user that the current controlled terminal is in a lost state. For example, the prompt message can be: "Warning: The controlled terminal signal cannot be received, the controlled terminal may have been lost, you can select the "one-key navigation" operation to find the controlled terminal." In addition, the controlled terminal tracking pop-up window includes a controlled terminal tracking control. In response to the trigger operation acting on the controlled terminal tracking control, the vehicle terminal displays the route guidance information of the controlled terminal on the navigation system interface.

[0073] It should be noted that the controlled terminal tracking control can be displayed in the navigation system interface or in the controlled terminal tracking pop-up window. The embodiment of the present application does not impose any restrictions on this, and the specific selection can be made according to the actual application scenario.

[0074] The embodiment of the present application provides a method for finding a controlled terminal, including: the vehicle terminal responds to the navigation setting instruction and displays the navigation system interface; when the vehicle terminal establishes a connection with the remote control terminal of the controlled terminal and the controlled terminal is in a lost state, the vehicle terminal responds to the trigger operation acting on the controlled terminal tracking control and displays the route guidance information of the vehicle terminal and the controlled terminal in the navigation system interface. The embodiment of the present application implements a one-key navigation operation through the controlled terminal tracking control of the navigation system interface in the vehicle terminal, and displays the route guidance information of the optimal path between the vehicle terminal and the controlled terminal in the navigation system interface, thereby assisting the car owner to find the lost controlled terminal along the route planned by the navigation in the first time, thereby greatly shortening the search time. Compared with the traditional search method, the embodiment of the present application can simplify the controlled terminal search process and improve the efficiency of finding the controlled terminal. In some embodiments of the present application, the method for finding the controlled terminal also includes S201 to S202:

[0075] S201: Receive location information of a controlled terminal sent by a remote control terminal.

[0076] In an embodiment of the present application, the vehicle-mounted terminal receives the location information of the controlled terminal sent by the remote control terminal in real time.

[0077] In the embodiment of the present application, the location information of the controlled terminal is sent in real time by the positioning module (GPS positioning module) of the controlled terminal.

[0078] S202: If the location information of the controlled terminal meets a preset condition, determine that the controlled terminal is in a lost state; wherein the preset condition includes one or more of the following:

[0079] The difference between the current time and the time when the location information was received is greater than or equal to a first preset threshold; wherein the current time is the time after the time when the location information was received;

[0080] The altitude information in the location information is greater than or equal to a second preset threshold;

[0081] The duration corresponding to the altitude information in the location information is greater than or equal to a third preset threshold; wherein the duration represents the duration of the altitude information of the controlled terminal in any altitude level;

[0082] The remote control terminal receives a collision signal and / or a drop signal sent by the controlled terminal;

[0083] The number of times the remote control terminal receives the transmission signal sent by the controlled terminal is less than or equal to a fourth preset threshold.

[0084] In an embodiment of the present application, the vehicle-mounted terminal will determine in real time whether the difference between the current time and the reception time of the last received location information of the controlled terminal is greater than the first preset threshold. If the vehicle-mounted terminal determines that the difference between the current time and the reception time of the last received location information is greater than or equal to the first preset threshold, it is determined that the controlled terminal is in a lost state at this time.

[0085] In the embodiment of the present application, the first preset threshold is preset in advance, for example, the first preset threshold is 2 minutes.

[0086] It can be understood that the vehicle-mounted terminal determines whether the controlled terminal is in a lost state based on the time difference between the current time and the time when the location information of the controlled terminal was last received, and can quickly judge the status of the controlled terminal. In this way, when it is determined that the controlled terminal is in a lost state, the vehicle-mounted terminal can prompt the user to find the controlled terminal at the first time, which can effectively shorten the search time of the controlled terminal, thereby increasing the search and rescue path of the controlled terminal, and greatly improving the probability of finding the controlled terminal.

[0087] In an embodiment of the present application, the vehicle-mounted terminal determines in real time whether the altitude information of the controlled terminal is greater than or equal to a second preset threshold. If the altitude information of the controlled terminal is greater than or equal to the second preset threshold, it can be determined that the controlled terminal is in a lost state. The second preset threshold is pre-set, for example, the second preset threshold is 2000 meters.

[0088] In an embodiment of the present application, the on-board terminal will determine in real time whether the duration corresponding to the altitude information of the controlled terminal is greater than or equal to the third preset threshold, that is, whether the duration of the altitude information of the controlled terminal in any altitude level is greater than or equal to the third preset threshold. In the case that the duration of the altitude information of the controlled terminal in any altitude level is greater than or equal to the third preset threshold, it can be determined that the controlled terminal is in a lost state at this time. Among them, the third preset threshold is preset in advance, for example, the second preset threshold is 3 minutes. Any altitude level is preset in advance, for example, any altitude level is 2000 meters to 3000 meters (high level).

[0089] In an embodiment of the present application, the vehicle-mounted terminal will determine in real time whether the remote control terminal has received the collision signal and / or fall signal sent by the controlled terminal. If the remote control terminal receives the collision signal and / or fall signal sent by the controlled terminal, it can be determined that the controlled terminal is in a lost state at this time.

[0090] In an embodiment of the present application, the vehicle-mounted terminal determines in real time whether the number of times the remote control terminal receives a transmission signal sent by the controlled terminal is less than or equal to a fourth preset threshold. If the number of times the remote control terminal receives a transmission signal sent by the controlled terminal is less than or equal to the fourth preset threshold, the controlled terminal can be determined to be in a lost state. The fourth preset threshold is pre-set, for example, 10 times.

[0091] It should be noted that the above-mentioned judgment conditions can be any combination of one or more conditions. The embodiments of the present application do not impose any limitations on this, and the specific selection can be made according to the actual application scenario.

[0092] like Figure 6 As shown, in S102, in response to the triggering operation of the tracking control on the controlled terminal, the implementation of displaying the route guidance information of the vehicle terminal and the controlled terminal in the navigation system interface may include S1021 to S1023:

[0123] It should be noted that the on-board screen (i.e. the navigation system interface) will display information such as the vehicle's current location, the location of the controlled terminal, and route guidance along the way to assist the owner in completing the search task and quickly track the last location of the controlled terminal before the signal was lost.
