However, the application scenarios of unmanned and intelligent devices are ever-changing. Once these intelligent devices encounter various unexpected situations, they will be damaged and unable to correctly receive operating instructions, unable to work normally, and even have the possibility of falling into the hands of the enemy. In order to cope with this situation and prevent the leakage of confidential information and core technologies, a self-protection mechanism should start working at this time, and the self-destruction mechanism is one of the effective mechanisms of this self-protection.

These terms are only used to distinguish a first element from another element. For example, a first image may be referred to as a second image, and similarly, a second image may be referred to as a first image without departing from the scope of this application. Both the first image and the second image are images, but they are not the same image.

[0043] See also Figure 1 The first aspect of the present invention discloses a self-destruction method in an automatic unmanned device; the method comprises:

[0044] Step S1, obtaining the status of the unmanned device and determining whether the unmanned device meets the self-destruction start condition;

[0045] In this step, different self-destruction start conditions are set according to the ever-changing application scenarios, and severity levels are set according to different self-destruction start conditions.

[0046] Step S2: if the self-destruction start condition is met, the severity level of the self-destruction start condition is determined; the severity level of the self-destruction start condition is at least divided into a first-level start condition and a second-level start condition; wherein the first-level start condition includes a functional failure of the unmanned device, unauthorized access to the unmanned device, and loss of control or connection of the unmanned device; the second-level start condition includes a biometric failure of the unmanned device, damage to the non-main CPU of the unmanned device, and receipt of a self-destruction command;

[0047] According to the method of the first aspect of the present invention, in step S2, the method for determining the functional failure of the unmanned equipment is:

[0048] When the unmanned equipment starts working, it starts timing its core processing task. If the data processed continuously within a fixed time is invalid data, it is determined that the function of the unmanned equipment is invalid.

[0049] The judgment method for loss of control or connection of unmanned equipment is as follows:

[0050] When no signal transmitted by the unmanned device is detected within a preset time or the unmanned device is observed to be out of control through other observation equipment, it is determined that the unmanned device is out of control or disconnected;

[0051] The methods for determining unauthorized access of unmanned devices include:

[0052] When abnormal login behavior, abnormal network traffic, abnormal system activity (such as abnormal use of CPU and memory resources) or abnormal privilege escalation is detected, it can be judged as a hacker intrusion, and then it can be determined that unmanned equipment has unauthorized access.

[0053] When we detect that the device is threatened or in other situations that require active destruction (such as being designed to self-destruct upon completion or not having enough battery power to return and not being able to wait for charging), we determine that the unmanned device has been captured by the enemy and can send a self-destruct command.

[0054] If the user's identity fails to be verified through biometrics, including fingerprints and irises, the device is considered to have been captured by the authorities, but to prevent accidental pick-up, the danger level is set to level 2 (or medium) and the self-destruct process is initiated.

[0055] If the self-destruction start condition is a first-level start condition, the software self-destruction process is started to destroy the stored data; if the self-destruction start condition is a second-level start condition, the hardware self-destruction process is started to destroy the target device of the unmanned device;

[0056] According to the method of the first aspect of the present invention, in step S2, the software self-destruction process includes:

[0057] The stored data is erased or the location of the key in the storage unit is erased, or the key instruction is rewritten. Specifically, when it is at a lighter level, if the instruction cannot be received for a long time, software self-destruction is used. This method uses the interface provided by the external memory device to erase the external memory such as flash, sata, etc., including the stored data and even the control program itself. It is also possible to execute an erase instruction on the location of the key in the storage unit, or rewrite the key, so that the encrypted data stored in the device cannot be cracked.

[0058] According to the method of the first aspect of the present invention, a high energy density battery, super capacitor, explosive or high temperature material is integrated in the unmanned equipment; in step S2, the hardware self-destruction process includes:

[0059] Control the release of energy from high-energy-density batteries, supercapacitors, explosives, or high-temperature materials to destroy the target devices of unmanned equipment. It should be noted that these energy sources need to have sufficient energy density and stability to ensure that the self-destruction process can be reliably triggered.

[0060] According to the method of the first aspect of the present invention, chemical corrosion materials are integrated into the unmanned equipment; in step S2, the hardware self-destruction process includes:

[0061] Controlled release of chemical corrosive materials to corrode or damage targeted devices in unmanned equipment.

[0062] Step S3: When the unmanned device is in the process of self-destruction, when a self-destruction interruption command is received, the software self-destruction process or the hardware self-destruction process is interrupted.

[0063] The method used for the self-destruction interruption of the software is to stop the erasing operation, but it can only stop the subsequent erasing actions, and the erased content cannot be restored.

[0064] In the physical destruction project, if it is carried out through circuit means such as capacitor discharge, a relay can be provided in the system. Once the destruction process needs to be interrupted, the relay is cut off to make the interruption process unable to continue.

[0065] The interruption of chemical destruction can be achieved by stopping the release of chemical substances. A software switch can be implemented through a logic circuit. Once the interruption is terminated, the release valve of the chemical substances is closed to interrupt its self-destruction process.

[0067] The first processing module 100 is configured to obtain the status of the unmanned device and determine whether the unmanned device meets the self-destruction initiation condition;

[0068] The second processing module 200 is configured to determine the severity level of the self-destruction initiation condition if the self-destruction initiation condition is met; the severity level of the self-destruction initiation condition is at least divided into a primary initiation condition and a secondary initiation condition; wherein the primary initiation condition includes a functional failure of the unmanned device, unauthorized access to the unmanned device, and loss of control or connection of the unmanned device; the secondary initiation condition includes a biometric recognition failure of the unmanned device, damage to the non-main CPU of the unmanned device, and receipt of a self-destruction instruction;

[0069] If the self-destruction start condition is a first-level start condition, the software self-destruction process is started to destroy the stored data; if the self-destruction start condition is a second-level start condition, the hardware self-destruction process is started to destroy the target device of the unmanned device;

[0070] The third processing module 300 is configured to interrupt the software self-destruction process or the hardware self-destruction process when receiving a self-destruction interrupt command when the unmanned device is in the process of the self-destruction process.

[0071] According to the system of the second aspect of the present invention, the steps for determining the functional failure of the unmanned equipment are:

[0072] When the unmanned equipment starts working, it starts timing its core processing task. If the data processed continuously within a fixed time is invalid data, it is determined that the function of the unmanned equipment is invalid.
