Description

Technical Field

[0001] The present invention relates to the field of unmanned vehicle safety control, and in particular to a device and method for physically destroying a multi-stage self-destructive unmanned vehicle control chip in an extreme out-of-control state. Background Art

[0002] With the deep integration of artificial intelligence and automotive electronics, autonomous vehicles have become a key development direction in the transportation sector. However, as the complexity of autonomous driving systems increases, their security risks are becoming increasingly prominent. In extreme scenarios such as hardware failure, cyberattacks, or software logic vulnerabilities, traditional safety mechanisms (such as software resets, redundant control, or circuit disconnection) may not be able to completely terminate the core control chip functions of the out-of-control vehicle, leading to secondary accidents or the risk of sensitive data leakage. Therefore, an ultimate protection method is urgently needed to quickly destroy the control chip after an autonomous vehicle loses control, ensuring safe braking of the autonomous vehicle.

[0003] Currently, common emergency response methods for unmanned vehicles experiencing loss of control primarily focus on software and hardware. At the software level, failure prediction algorithms based on deep learning and multi-sensor data fusion offer excellent real-time performance and accuracy. However, these technologies rely on the chip's inherent computing power. If the chip becomes unresponsive due to physical damage or program crashes, the risk of failure increases dramatically. At the hardware level, overcurrent protection fuses can cut power, but their design objective is circuit protection, not chip destruction. After a fuse blows, the chip can still be restored through repair or reverse engineering, making them difficult to meet the requirements of high-security scenarios.

[0004] In summary, the key technical challenge facing the industry is how to develop a compact, low-cost physical self-destruct solution compatible with automotive-grade chips and ensure complete termination of chip functionality in the event of a loss of control in an unmanned vehicle. This solution must achieve irreversible destruction of chip functionality while maintaining miniaturization and cost control, effectively safeguarding system and data security. Summary of the Invention

[0005] Purpose of the invention: In response to the problems existing in the above-mentioned prior art, the present invention proposes a multi-stage self-destruction device and method for the physical destruction of unmanned vehicle control chips. In an extreme out-of-control state, a multi-stage physical self-destruction mechanism of "power supply destruction + chip self-destruction" is adopted. The power supply is cut off by energetic materials to isolate the energy supply, and then the chip is destroyed by mechanical impact to achieve double irreversible destruction; ensuring the termination of vehicle operation and irreversible destruction of data in extreme out-of-control scenarios, and realizing the ultimate safety protection of automotive-grade chips.

[0006] Technical solution: The physical destruction device of the multi-stage self-destructive unmanned vehicle control chip of the present invention is installed below the unmanned vehicle control chip, and the surface of the physical destruction device is closely attached to the bottom of the control chip; the power line passes over the physical destruction device of the multi-stage self-destructive unmanned vehicle control chip and is closely attached to the surface of the third-level energetic material.

[0007] The physical destruction device of the multi-stage self-destructive unmanned vehicle control chip of the present invention includes a moving slider, a base plate and a secondary energetic material. The moving slider includes a slider and a primary electromagnetic coil.

[0008] A safety pin is provided at the top of the slider, and a first-level installation groove for fixing the second-level energetic material and a installation groove for fixing the first-level electromagnetic coil are opened at the middle end; a wire is provided at the end of the slider.

[0009] The bottom plate includes a base plate and a secondary electromagnetic coil; a safety pin slot for fixing a safety pin and a slide slot for fixing a slider are provided in the middle of the base plate; a groove for installing the secondary electromagnetic coil is provided at the end of the base plate; a wire is laid on the surface of the base plate; a three-level energy conversion element is connected in series with the wire; a three-level energy-containing material is provided above the three-level energy conversion element; and the three-level energy-containing material is connected to a power line.

[0010] There is a first-level energetic material at the bottom of the safety pin slot, a first-level energy conversion element below the first-level energetic material, and a second-level energy conversion element at the bottom of the slider; under the action of the first-level energetic material, the first-level electromagnetic coil and the second-level electromagnetic coil, the slider moves along the slide slot until the second-level energetic material is aligned with the second-level energy conversion element.

[0011] The control method of the physical destruction device of the multi-stage self-destruction unmanned vehicle control chip of the present invention comprises the following steps:

[0012] (1) When the physical destruction device of the multi-stage self-destruction unmanned vehicle control chip is in a safe state, the circular safety pin at the top of the slider is placed in the safety pin groove of the base plate, so that the moving slider is limited to the top of the base plate slide groove, the first-level energy conversion element is not powered, and the device is in an inactive state.

[0013] (2) When the unmanned vehicle is working normally, the secondary energetic material and the secondary energy conversion element are staggered, and the wires are in an open circuit state, ensuring the safety of the unmanned vehicle control chip and power line.

[0014] (3) When the unmanned vehicle loses control, the physical destruction device of the unmanned vehicle control chip enters the excited state, the first-level energy conversion element is energized, and the first-level energy-containing material is excited to destroy the circular safety pin at the top of the slider, releasing the limit of the moving slider. The second-level electromagnetic coil at the end of the bottom plate has an opposite current to the first-level electromagnetic coil and generates a traction force to push the slider to the end of the slide groove of the substrate, so that the second-level energy-containing material and the second-level energy conversion element are aligned, and the copper wire fixed at the end of the slider forms a short circuit with the wire on the surface of the substrate, so that the second-level energy conversion element enters the excited state.

[0015] (4) When the physical destruction device of the unmanned vehicle control chip enters the excited state, the secondary energy conversion element is energized to excite the secondary energetic material to destroy the base plate and pins of the control chip, thereby realizing the physical self-destruction of the unmanned vehicle control chip.

[0016] (5) When the physical destruction device of the control chip of the unmanned vehicle enters the excited state, the wire and the copper wire are connected in series with the three-level energy conversion element to form a pathway. After the three-level energy conversion element is energized, the three-level energetic material is stimulated to act and destroy the power line, thereby cutting off the power supply of the unmanned vehicle and achieving braking after the unmanned vehicle loses control.

[0017] In step (2), the secondary electromagnetic coil is energized to generate an alternating magnetic field, driving the primary electromagnetic coil to generate reverse eddy currents, forming a closed magnetic circuit with the secondary electromagnetic coil; when the currents of the primary electromagnetic coil and the secondary electromagnetic coil are opposite, an axial traction force is generated to push the slider along the slide groove until the secondary energetic material is aligned with the secondary energy conversion element.

[0018] Working principle: The physical destruction device of the multi-stage self-destructive unmanned vehicle control chip of the present invention has a safe state and an excited state.

[0019] (1) In the safe state, the circular safety pin at the top of the slider is supported by a brittle alloy material, which forms a clearance fit with the safety pin slot of the substrate, so that the moving slider is limited to the top of the substrate slide slot, limiting the horizontal movement of the moving slider, so that the secondary energetic material and the secondary energy conversion element are staggered, and the wire is in a disconnected state, protecting the control chip and power supply from damage.

[0020] (2) When the unmanned vehicle loses control, the first-level energy conversion element excites the first-level energetic material. The first-level energetic material generates a directional detonation to destroy the circular safety pin at the top of the slider. The destruction of the safety pin directly releases its axial constraint on the moving slider, causing the moving slider to move horizontally in the substrate slot. The second-level electromagnetic coil at the end of the base plate is energized to generate an alternating magnetic field, which drives the first-level electromagnetic coil to generate reverse eddy currents through the magnetic-electric coupling effect. The first-level electromagnetic coil is fixed in the square electromagnetic coil mounting slot of the moving slider, forming a closed magnetic circuit with the second-level electromagnetic coil. When reverse currents are passed through the two coils, an axial traction force F=IL×B is generated according to the Lorentz force law, pushing the moving slider to move along the substrate slot toward the end until the second-level energetic material and the second-level energy conversion element reach a coaxial alignment state, as shown in FIG. Figure 7 As shown in the figure. Under the action of the electromagnetic field, the primary electromagnetic coil pulls the moving slider toward the end of the moving slider slot on the substrate, aligning the secondary energetic material and the secondary transducer. The copper wire fixed to the end of the moving slider forms a short circuit with the wire on the substrate surface, and the secondary transducer enters an excited state through the Joule heating effect.

[0021] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0022] (1) The present invention is based on a multi-stage self-destruct mechanism for the physical destruction of control chips in unmanned vehicles, and is applied to safety control in extreme out-of-control conditions. The present invention employs a two-stage safety mechanism of "safety pin + electromagnetically driven moving slider" to prevent the accidental destruction of the chip and power cord caused by abnormal triggering of the physical destruction device of the control chip, thereby improving the safety of the unmanned vehicle safety control system.

[0023] (2) The present invention adopts a multi-level physical self-destruction mechanism of "power supply destruction + chip self-destruction". On the one hand, it destroys the power supply and cuts off the power supply of the unmanned vehicle, realizing slow braking after the unmanned vehicle loses control. On the other hand, it terminates the chip function and physically crushes the core structure, reducing the risk of data leakage and hardware repair of the unmanned vehicle.

[0032] like Figures 1 to 8As shown, the physical destruction device for the multi-stage self-destruction unmanned vehicle control chip of the present invention includes a control chip 1, a moving slider 2, a base plate 3, a primary energetic material 4, a primary energy conversion element 5, a tertiary energetic material 7, and a secondary energy conversion element 8. The moving slider 2 is composed of a slider 9, a secondary energetic material 10, a coil 11, a magnetic core 12, and a copper wire 13; the base plate 3 is composed of a substrate 14, a wire 15, a tertiary energy conversion element 16, a magnetic core 17, and a coil 18.

[0033] This embodiment shows a side view of the structure of the physical destruction device for the unmanned vehicle control chip, illustrating the stacking of the three-stage self-destruction device in a safe state. The first-stage self-destruction device consists of a first-stage energetic material 4 and a first-stage transducer 5. These materials are stacked one above the other, with the upper surface of the first-stage energetic material 4 in close contact with the bottom of the safety pin slot in the substrate 14. The second-stage self-destruction device consists of a second-stage energetic material 10 and a second-stage transducer 8. The second-stage transducer 8 is in close contact with the bottom of the moving slider 2. In the safe state, it is offset from the second-stage energetic material 10, and in the activated state, it is aligned with the second-stage energetic material 10. The third-stage self-destruction device consists of a third-stage energetic material 7 and a third-stage transducer 16. The third-stage transducer 16 is stacked one above the third-stage energetic material 7, with the upper surface of the third-stage energetic material 7 in close contact with the power line 6.

[0034] In this embodiment, the slider 9 is in the shape of a square flat plate, with a circular safety pin 91 provided at the top of the slider 9, and a circular energetic material primary mounting groove 92 and a square electromagnetic coil mounting groove 93 at the middle end, which are used to install energetic material 10 and a primary electromagnetic coil, wherein the primary electromagnetic coil is composed of a primary coil 11 and a primary magnetic core 12, and a copper wire 13 is fixed at the end.

[0035] The bottom plate 3 consists of a substrate 14, a wire 15, a three-stage energy conversion element 16, a magnetic core 17, and a coil 18; the substrate 14 is a square flat plate with a safety pin slot 31 and a moving slider slot 32 in the middle; the surface of the substrate 14 at the end of the slot 32 is paved with a wire 15; the wire 15 is connected in series with the three-stage energy conversion element 16; a groove 33 is provided at the end of the substrate 14 for installing a secondary electromagnetic coil, which consists of a secondary magnetic core 17 and a secondary coil 18.

[0036] When the physical destruction device of the multi-stage self-destruction unmanned vehicle control chip is in a safe state, the circular safety pin 91 at the top of the slider 9 is placed in the safety pin slot 31 of the substrate 14, so that the moving slider 2 is limited to the top of the moving slider slot 32 of the substrate 14. The primary energy conversion element 5 is not powered and the device is in an inactive state; the secondary energetic material 10 and the secondary energy conversion element 8 are staggered, and the wire 15 is in an open circuit state. At this time, both the secondary self-destruction device and the tertiary self-destruction device cannot function normally, ensuring the safety of the unmanned vehicle control chip 1 and the power line 6.

[0037] The physical destruction device of the unmanned vehicle control chip enters the excited state. The primary energy conversion element 5 is energized, stimulating the primary energetic material 4 to destroy the circular safety pin 91 at the top of the slider 9, releasing the limit of the moving slider 9. The secondary electromagnetic coil at the end of the bottom plate 3 is energized to generate a magnetic field, attracting the moving slider 9 to move toward the end of the moving slider slot 32 of the substrate 14, so that the secondary energetic material 10 and the secondary energy conversion element 8 are aligned. The copper wire 13 fixed at the end of the slider 9 forms a short circuit with the wire 15 on the surface of the substrate 14, and enters the excited state. When the physical destruction device of the unmanned vehicle control chip enters the excited state, the secondary energy conversion element 8 is energized, stimulating the secondary energetic material 10 to destroy the bottom plate and pins of the control chip 1; the wire 15 and the copper wire 13 are connected in series with the tertiary energy conversion element 16 to form a pathway. After the tertiary energy conversion element 16 is energized, it stimulates the tertiary energetic material 7, which acts on and destroys the power line 6, causing the unmanned vehicle to lose power.
