[0021] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0022] The following will describe in detail various embodiments of the present invention, and will be illustrated with drawings. In addition to these detailed descriptions, the present invention can also be widely implemented in other embodiments, and any easy replacement, modification, and equivalent changes of the embodiments are included in the scope of the present invention, and are subject to the subsequent claims. In the description of the specification, in order to give the reader a more complete understanding of the present invention, many specific details and implementation examples are provided; however, these specific details and implementation examples should not be regarded as limitations of the present invention. In addition, well-known steps or elements are not described in detail to avoid unnecessary limitations of the present invention.

[0023] Please refer to Figure 1, which is a schematic diagram of a drone 10 according to an embodiment of the present invention. The drone 10 may include a housing 11, a disassembly state judgment system 12 and a controller 13 contained in the housing 11. The controller 13 may send a control signal S to control the flight of the drone 10. The housing 11 has at least one housing component, such as a housing component 111 and a housing component 112. The housing component 111 and the housing component 112 each include two components that can be separated from each other. For example, the housing component 111 may include a housing body 111a and a cover 111b, and a user may repair the parts inside the drone 10 by disassembling the cover 111b. The housing component 112 may include a housing body 111a and a protective cover 111c, and the protective cover 111c covers at least one data transmission interface or a pluggable memory card. The user may open the protective cover 111c and connect the data transmission interface through a transmission line to transmit data, or remove the memory card to access data. Once the cover 111 b or the protective cover 111 c and the casing body 111 a are separated from each other, the disassembly state determination system 12 can determine whether the disassembly state is legal or illegal.

[0024] Figure 2 FIG. 1 is a block diagram of a disassembly status determination system 12 of a drone 10 according to an embodiment of the present invention. Figure 1 and Figure 2 The status reading system 12 may include a disassembly detection unit 121, a position detection unit 122, a storage unit 123, a processing unit 124 and a signal receiver 125. The processing unit 124 is coupled to the disassembly detection unit 121, the position detection unit 122, the storage unit 123 and the signal receiver 125. The processing unit 124 may be included in a processor, for example, through software components (such as program codes, instructions, data, files), hardware components (such as logic circuits, integrated circuits, chips, circuit boards) or a combination thereof, and operates under the control of the processor to realize its functions. The signal receiver 125 may receive the control signal S provided by the controller 13.

[0025] The disassembly detection unit 121 is disposed on at least one housing component of the drone 10, such as the housing components 111 and 112, to provide a body status information according to whether the at least one housing component is separated. In one embodiment, the disassembly detection unit 121 can be a Hall sensor. Figure 3 FIG. 1 is an example of a disassembly detection unit 121 being a Hall sensor according to an embodiment of the present invention. Figure 3As shown, the disassembly detection unit 121 can be disposed on the casing body 111a of the casing assembly 111, and a magnet element MN is disposed on the cover 111b of the casing assembly 111. The position of the magnet element MN corresponds to the disassembly detection unit 121, so that the disassembly detection unit 121 can detect the magnetic field F of the magnet element MN. Once the magnetic field F changes, for example, when the cover 111b and the casing body 111a move away from each other, the disassembly detection unit 121 can sense the change of the magnetic field F and provide a body status information.

[0026] The position detection unit 122 is used to detect the current position of the drone 100. In one embodiment, the position detection unit 122 can obtain the GPS coordinates of the drone 100 through a global positioning system (GPS).

[0027] The storage unit 123 is, for example, a hard disk, a memory card, or a memory, for storing a safe location list. The safe location list can be set in advance, and it can record any authenticated or trusted location information. For example, authenticated or trusted locations can include base locations, maintenance station locations, training station locations, etc. Authenticated or trusted locations can also include the take-off location of the drone 10. In one embodiment, the authenticated or trusted location information can be GPS coordinates.

[0028] In one embodiment, the safe location list is modifiable. For example, one can update the base location, maintenance station location, practice station location, etc. recorded in the safe location list, or add any authenticated or trusted location information other than the base location, maintenance station location, practice station location, etc. In one embodiment, when the drone 10 takes off for the first time at a location, the processing unit 124 can add the take-off location to the safe location list based on the current location detected by the location detection unit 122. In one embodiment, as the take-off location of the drone 10 changes, the processing unit 124 can also update the take-off location in the safe location list in a timely manner based on the current location detected by the location detection unit 122.

[0029] Figure 4 FIG. 1 is a flow chart of a method S10 for determining the disassembly status of a drone 10 according to an embodiment of the present invention. Figure 1 , Figure 2 and Figure 4 , the disassembly state determination method S10 comprises the following steps. In step S11, the disassembly detection unit 121 provides a body state information. In step S12, the processing unit 124 determines whether at least one shell component is in a disassembly state according to the body state information in step S11. If not, the process returns to step S11; if the processing unit 124 confirms that at least one shell component is in a disassembly state, the process executes step S13. Figure 3 For example, if the cover 111b and the casing body 111a are away from each other, the disassembly detection unit 121 can sense the change of the magnetic field F and provide body status information. The processing unit 124 can determine that the casing assembly 111 is currently in a disassembled state based on the body status information.

[0030] In step S13, the processing unit 124 determines whether the current position of the drone 10 can be obtained. For example, if the position detection unit 122 can detect the current position of the drone 10, the processing unit 124 determines that the result of step S13 is "yes", and then executes step S14. In step S14, the processing unit 124 can determine whether the current position of the drone 10 exists in the safe position list according to the safe position list stored in the storage unit 123. If it exists in the safe position list, it means that the drone 10 is currently located at any authenticated or trusted location, and the processing unit 124 determines that the disassembly state of at least one shell component is legal disassembly, as shown in step S15. For example, if the position detection unit 122 detects that the current position of the drone 10 is the GPS coordinates of the maintenance station location, and the processing unit 124 confirms that the GPS coordinates of the maintenance station location already exist in the safe position list of the storage unit 123, the processing unit 124 determines that the disassembly state is legal disassembly.

[0031] In step S14, if the processing unit 124 determines that the current location of the drone 10 does not exist in the safe location list, it means that the drone 10 is currently located in an unauthenticated and untrusted location, which means that the drone 10 is likely to have been intercepted by others in order to steal confidential information inside. Then, the processing unit 124 determines that the disassembly status of at least one shell component is illegal disassembly, such as step S17.

[0032] In one embodiment, if the disassembly status of at least one housing component is determined to be illegal disassembly, the processing unit 124 may further erase the data stored in the storage unit 123 and / or at least one storage device 126 of the drone 10 to prevent confidential information from being stolen by malicious persons.

[0033] On the other hand, in step S13, if the position detection unit 122 cannot detect the current position of the drone 10, for example, when the drone 10 is interfered by a signal jammer and loses the GPS signal, so that the position detection unit 122 cannot detect the current position of the drone 10, the processing unit 124 determines that the result of step S13 is "no", and then executes step S16. In step S16, the processing unit 124 can determine whether the strength of the control signal S of the controller 13 is less than the threshold value. If it is determined that the strength of the control signal S is less than the threshold value, it means that the drone 10 is currently not within the control range of the controller 13, and may have entered an unsafe position, or the control signal S of the controller 13 has been blocked by others, then the processing unit 124 determines that the disassembly state of at least one shell component is illegal disassembly, such as step S17. If in step S16, the processing unit 124 determines that the strength of the control signal S is not less than the threshold value, for example, greater than or equal to the threshold value, it means that the drone 10 is still within the control range of the controller 13, and the controller 13 can still control the flight of the drone 10. Therefore, the processing unit 124 determines that the disassembly status of at least one shell component is legal disassembly, such as step S15.

[0034] Figure 5 FIG. 1 is a flow chart of a method S10′ for determining the disassembly status of a drone 10 according to another embodiment of the present invention. Figure 4 The differences of the disassembly status judgment method S10 process are described, and the other identical or similar aspects are not repeated here.

[0035] and Figure 4 The difference between the disassembly status judgment method S10 is that: in step S14, if the processing unit 124 determines that the current position of the drone 10 is not in the safe position list, step S16 is executed, and the processing unit 124 determines whether the strength of the control signal S of the controller 13 is less than the threshold value, and determines whether the drone 10 is currently within the control range of the controller 13 based on the strength of the control signal S of the controller 13, and uses this as the basis for determining whether the disassembly status is legal. In other words, even if the current position of the drone 10 is not in the pre-set safe position list, as long as the controller 13 can still control the flight of the drone 10, it is still a legal disassembly.

[0036] According to the aforementioned drone, when the drone may be disassembled by others, the disassembly behavior is judged to be legal by judging whether the current location of the drone is in the safe location list. Furthermore, when the disassembly behavior is judged to be illegal, the data stored in the storage unit and / or the storage device of the drone is erased to prevent confidential information from being stolen by malicious persons.

[0037] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
