Users who accidentally recover unmanned aerial vehicles can simply investigate the aerial photography equipment carried on unmanned aerial vehicles. Or measuring equipment can obtain the data currently obtained by the unmanned aerial vehicle.

This situation is very fatal for the situation where the data obtained by the unmanned aerial vehicle has confidentiality requirements. Just imagine, when an unmanned aerial vehicle that performs a shooting mission at a confidential place after application is accidentally controlled by a third party using data intrusion or crashes and is acquired by an uninformed third party during flight or recovery, At this time, the security of the captured data will not be guaranteed at all.

FIG. 3 is a schematic structural diagram of an unmanned aerial vehicle with a data deletion device according to an embodiment of the present invention. The embodiment of the present invention will be described in detail with reference to FIG. 3 .

For occasions that require higher data security, it is required that once out of control or loss of connection occurs, the data must be destroyed reliably. In this case, the corresponding data storage part of the unmanned aerial vehicle needs to regularly start data destruction processing, and the processing module 3 actively sends an inquiry to the user terminal to confirm whether it is currently under the normal control of the user. Under the control, a signaling is automatically returned as the verification result. After the data deletion processing receives the verification result signaling, the data deletion processing will not be implemented, and the inquiry process will be reset. After a certain period of time, restart Ask again. Once the processing module 3 fails to obtain normal signaling feedback, for example, it may be because the user has actually lost contact with the UAV, or if the UAV motor loses power and crashes, then the program determines that because some Specific reasons, such as information interference, unmanned aerial vehicles out of control and other events may occur, but the processing module 3 no longer determines the specific content of these unspecified reasons, and directly starts the data deletion command.

As shown in Figure 3, one embodiment of the present invention provides a kind of unmanned aerial vehicle with data deletion device, comprises data deletion device 1 and storage module 2, and described data deletion device 1 comprises processing module 3 and data deletion module 4. The data deletion module 4 is connected to the storage module 2, and the processing module 3 communicates with the user terminal 8 via the first wireless communication module 7 and sends a confirmation to the user terminal 8 that the UAV is in a state of control and communication confirmation indication, when the user terminal 8 does not feed back the confirmation indication, the processing module 3 judges that the unmanned aerial vehicle is out of control and/or out of contact, and the data deletion module 4 generates a data deletion instruction and deletes the stored Data in module 2.

In this way, the safety of the data stored on the unmanned aerial vehicle is guaranteed. No matter what unexpected situation occurs, as long as the processing module 3 does not get the proper safety signaling feedback, the data deletion module will be automatically started to delete data such as those collected. The received signaling and related data about the flight tasks that the unmanned aerial vehicle has carried out, such as flight trajectory, flight altitude, flight time, flight speed, etc. At this time, the normal flight control of the UAV is not affected. In other words, the processing of this data is only made for the requirement of data security, and will not substantially affect the flight control of the UAV. Will not increase the risk of aircraft crash. Even if a misjudgment occurs, the worst result is the loss of all kinds of data collected in previous missions. In addition, the confirmation instruction issued by the processing module 3 can be executed repeatedly and cyclically, not limited to the cycle according to a certain time period, but also can be triggered based on certain conditions, such as triggering when the unmanned aerial vehicle starts and is on standby. The key task node of a good UAV is triggered, and the verification mechanism for triggering the task under these conditions is still the same to collect relevant feedback from the user terminal. If no feedback is obtained from the user terminal, data processing will be implemented.

In addition, since the data destruction program is only an operation on the storage components, it consumes less energy, so the energy source of the data destruction program can be implemented solely based on a certain power of the unmanned aerial vehicle, regardless of the power provided by the unmanned aerial vehicle to the motor In other words, even if the power used by the unmanned aerial vehicle to supply power to the motor fails, the normal work of the data destruction module will not be affected, and the monitoring can be carried out normally.

The data deletion module 4 is connected to the storage module 2. When the processing module 3 judges that the UAV is out of control or out of contact, the processing module 3 uses a second wireless communication system different from the first wireless communication module 7. The module 9 sends a confirmation indication whether to delete data to the user terminal 8, and when the user terminal 8 confirms the data deletion, the data deletion module 4 generates a data deletion instruction and deletes the data in the storage module 2.

The above-mentioned accompanying drawings 2 and 3 respectively give different specific embodiments, among which the one in the accompanying drawing 2 is relatively conservative, only when it is determined that an accident occurs, or when the user clearly instructs, the data will be destroyed; while the accompanying drawing 3 is relatively Radical, as long as the user does not give a safety signal to disarm, the UAV will destroy the data at regular intervals or under specified conditions. Figure 4 shows a specific embodiment between the above two solutions. On the basis of the above two solutions, a step of confirmation based on a third-party communication frequency band is added. That is, under any scheme, once it is decided to implement data destruction, a final confirmation instruction will be issued to the user through a third-party communication frequency band different from the current control frequency band of the UAV, such as a confirmation instruction to the user through 4G , indicating that unmanned aerial vehicles are about to implement data deletion, asking the user to confirm whether to implement conservative practices, or asking users to confirm whether to reverse safe practices. Data deletion will only be initiated if this step has been confirmed by the user or has not yet been revoked by the user.
