In an embodiment of the present application, the acquired position information includes an identification code, which is used to uniquely identify the unmanned aerial vehicle 10. The identification code can also be pre-stored in the user terminal 20.

[0082] The GSM module 105 is configured to send the position information obtained by the GPS module 104 to the cloud server 30.

The system for searching the unmanned aerial vehicle provided by the embodiment of the present application can make the user corresponding to the user terminal 20 accurately acquire the specific position of the unmanned aerial vehicle 10 according to the GSM module 105, the GPS module 104 and the cloud server 30, ensure that the unmanned aerial vehicle 10 will not be lost, provide convenience for the user to search the unmanned aerial vehicle 10, and reduce the loss of the user.

[0089] The present application also provides a method for searching the unmanned aerial vehicle, the unmanned aerial vehicle 10 in the above embodiment can be used to execute the method for searching the unmanned aerial vehicle, and details can be referred to Figure 3 , the method comprises:

[0090] S101, acquiring the position information of the unmanned aerial vehicle.

[0091] In an embodiment of the present application, the unmanned aerial vehicle 10 can acquire its position information through the GPS module 104 carried by the unmanned aerial vehicle 10. The position information includes an identification code. The identification code corresponds to the unmanned aerial vehicle 10 uniquely. In an embodiment of the present application, the position information includes GPS longitude and latitude information, and in other embodiments, the position information can include the environmental image information within a preset range around the unmanned aerial vehicle 10 at a certain longitude and latitude, in addition to the longitude and latitude information of the unmanned aerial vehicle 10.

[0094] The GPS module 104 acquires the location information of the UAV 10 and sends the location information to the cloud server 30 through the GSM module 105, both of which can be periodic acquisition and sending, and the corresponding periods of the two processes can be the same or different. When sending the location information to the cloud server 30 through the GSM module 105, the location information can be first processed, which includes filtering out noise data and compressing and packaging the filtered data, thereby improving the transmission efficiency of the location information. In some embodiments, the GPS module 104 can also include a backup battery, which is used to power the UAV 10 when the power battery of the UAV 10 is lost, so that the GPS module 104 can continue to detect the location information of the UAV 10, and the GSM module 105 can continue to send the location information to the cloud server 30. The power battery is a battery included in the UAV 10 itself.

The UAV 10 can start detecting whether its power battery is powered when it detects that it loses connection with the user terminal 20, and the specific detection method can be realized by a pre-set control program in the UAV 10. When the power battery loses power, the backup battery can be controlled by a pre-set instruction to start working, thereby ensuring the power endurance of the UAV 10, which also provides protection for searching for the UAV 10.

[0096] It can be understood that after the location of the UAV 10 is determined, the user can not be able to find the UAV 10 in time due to the complex environment of the location of the UAV 10, so in some embodiments, the method further comprises:

During the guidance, the user can be prompted by voice and / or image. In this embodiment, the user terminal 20 can be a device that realizes human-computer interaction by using a user interface, such as a computer, a PDA, a tablet computer, a smart phone, a smart bracelet, or the like. The user can operate the user interface displayed on the user terminal 20.

[0110] S205, send a search instruction to the UAV, so that the UAV sends an alarm information to guide the user to search for the UAV, wherein the alarm information comprises at least one of flashing of an indicator light and sound.

[0111] In an embodiment of the present application, the alarm information comprises at least one of flashing of an indicator light of the UAV 10 and a warning sound emitted by the UAV 10, so as to attract the attention of the user and help the user quickly find the UAV 10. In an embodiment of the present application, the indicator light of the UAV 10 can be an indicator light located on the arm 102 and / or the body 101 of the UAV 10. A sound alarm module can be provided on the UAV 10 to emit a warning sound.

[0112] In some embodiments, after the user terminal 20 acquires the position information of the UAV 10, refer to Figure 5 , the user terminal 20 is further configured to perform the following method:

[0113] S301, detecting environmental information in a preset range corresponding to the position information;

[0114] The preset range corresponding to the position information can be customized by the user terminal 20 system, or can be set on the user terminal 20 according to personal preferences. The environment information includes the natural environment and the human environment of the current location of the unmanned aerial vehicle 10, and the environment information can be detected by acquiring pictures, videos, audio, etc. within the preset range of the position information.

[0115] Detecting the environment information within the preset range corresponding to the position information includes capturing pictures or videos or audio within the preset range of the position information by the camera included in the unmanned aerial vehicle 10, and determining the environment information within the predetermined range according to the pictures or videos or audio. Detecting the environment information within the preset range corresponding to the position information also includes the user terminal 20 accessing the Internet and searching for pictures, videos, audio, etc. of the location corresponding to the longitude and latitude on the Internet according to the longitude and latitude in the position information, so as to determine the environment information within the predetermined range according to the pictures, videos, audio, etc.

[0116] S302, judge whether the complexity of the environment information matches the preset environment complexity;

[0117] When the complexity of the environment information is the same as the preset environment complexity, or the complexity of the environment information is higher than the preset environment complexity, the complexity of the environment information matches the preset environment complexity, otherwise, it does not match. Wherein, the complexity of the environment information is higher than the preset environment complexity means that the environment corresponding to the environment information is more complex than the preset environment, and the complexity is mainly measured by the object factors in the surrounding environment of the current location of the unmanned aerial vehicle 10, including people, weather conditions, geographical environment, etc. The complexity of the current environment can be judged by one of the object factors, or several object factors can be combined to comprehensively judge the complexity of the current environment.

[0118] For example, the current location of the unmanned aerial vehicle 10 is a playground, and the number of people on the playground is greater than a preset threshold, so it is determined that the complexity is higher than the preset environment complexity, and the complexity of the environment information matches the preset environment complexity.

[0119] For example, the current location of the unmanned aerial vehicle 10 is raining, and the location is on a hill, so it is determined that the complexity is higher than the preset environment complexity, and the complexity of the environment information matches the preset environment complexity.

[0120] If the complexity of the environment information matches the preset environment complexity, the following step S303 is performed:

[0121] S303, sending a search instruction to the cloud server, so that the drone sends preset alarm information according to the search instruction sent by the cloud server.

[0122] It can be understood that when the environment information of the current location of the drone 10 is relatively complex, even if the user obtains the specific location information of the drone 10, it is not easy to find the drone 10 when reaching the vicinity of the location information due to the complex environment. Therefore, the user terminal 20 sends the search instruction to the cloud server 30, and the cloud server 30 forwards the search instruction to the drone 10, so as to trigger the drone 10 to send the preset alarm information.

[0123] The preset alarm information includes at least one of flashing of an indicator light of the drone and sending of preset sound by the drone.

[0124] In some embodiments, when the complexity of the environment information matches the preset environment complexity, the user terminal 20 is further configured to: acquire historical location information of the drone 10; generate a flight trajectory of the drone 10 according to the historical location information, and display the flight trajectory on a display device, so as to guide a user corresponding to the user terminal 20 to search for the drone 10 according to the displayed flight trajectory.

[0125] The user terminal 20 acquires the historical location information of the drone 10 from the cloud server 30. The historical location information refers to location information corresponding to each moment before the drone 10 loses contact with the user terminal 20. These location information can be represented by a point, and the flight trajectory is generated by connecting these points. The end point of the flight trajectory is the point corresponding to the acquired location information.

[0126] The display of the flight trajectory specifically includes: opening a map on the display interface of the user terminal 20, and displaying the flight trajectory on the map. The flight trajectory on the map can be highlighted by color or brightness, and the map can be a two-dimensional map or a three-dimensional stereoscopic map.

[0127] The cloud server 30 in the embodiment of the application can be a server, a server cluster composed of several servers, or a cloud computing service center. The cloud server 30 is configured to receive and store the position information sent by the UAV 10, query the position information of the UAV 10 corresponding to the identification code, and send the position information to the user terminal 20, so that the user terminal 20 searches for the UAV 10 according to the position information. The cloud server 30 is also configured to receive the search instruction sent by the user terminal 20 and forward the search instruction to the UAV 10. In the embodiment, the cloud server 30 has the functions of data storage, data management, and data transmission, and can manage multiple UAVs 10 and communicate with multiple user terminals 20 at the same time.
