Description

Technical Field

[0001] This invention belongs to the field of data destruction technology, specifically relating to a register chip data destruction system in a power-off environment. Background Technology

[0002] Currently, register chips require external power supply and software-based destruction of internal data.

[0003] If the equipment needs to be destroyed due to lack of external power, it needs to be powered by the small backup battery built into the equipment. These small backup batteries are affected by environmental factors and their actual service life is only a few years before they need to be replaced regularly to ensure that this function can be maintained. If the equipment is scattered in various places and there are a large number of them, it is difficult to replace them.

[0004] To address the aforementioned pain points during use, this invention employs a method that eliminates the need for a small backup battery, using self-excited electrical pulses to destroy the data inside the register chip. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The technical problem to be solved by the present invention is how to provide a register chip data destruction system in a power-free environment, so as to solve the problem of destroying internal data of register chips through software in an environment with external power supply.

[0007] (II) Technical Solution

[0008] To address the aforementioned technical problems, this invention proposes a register chip data destruction system for a power-free environment. The system includes: a register chip, printed circuit board lines, wires, and a destruction trigger. The destruction trigger includes: a conductive terminal, a piezoelectric ceramic, a gasket, a hammer, a compression spring, and a housing.

[0009] The register chip, located on the circuit board, has a pointed tip at the position where its chip pin printed line aligns with the printed line on the circuit board;

[0010] The printed circuit line is located on the circuit board, with one end aligned with the tip and the other end connected to the wire.

[0011] One end of the wire is connected to the printed line on the circuit board, and the other end is connected to the conductive terminal of the destroy trigger.

[0012] Conductive terminal: One end extends out of the through hole on the first end face of the outer shell and is connected to a wire, and the other end is connected to the piezoelectric ceramic, serving as the discharge terminal of the piezoelectric ceramic and sealing the destroyer at the same time;

[0013] Piezoelectric ceramics: One end of a piezoelectric ceramic is connected to a conductive terminal, and the other end is connected to a gasket. When compressed, it generates high-voltage electrical energy.

[0014] Gasket: As a conductive terminal of the piezoelectric ceramic, it also serves to disperse the force when the hammer impacts the piezoelectric ceramic, so that the pressure is evenly distributed and transmitted to the piezoelectric ceramic.

[0015] Hammer body: includes: hammer head, cylindrical rod and pull ring. A gap is provided between one side of the hammer head and the pad for impacting the piezoelectric ceramic pad. The cylindrical rod is fixedly connected to the other side. The cylindrical rod passes through the through hole on the second end face of the outer shell and is connected to the pull ring. A pre-made indentation is provided in the middle of the cylindrical rod. The pre-made indentation forms a weak link. The pre-made indentation is located inside the outer shell.

[0016] Compression spring: The part of the cylindrical rod located inside the outer shell, which is compressed and then released to cause the hammer to strike the piezoelectric ceramic;

[0017] Outer shell: hollowed out in the middle, with through holes at both ends.

[0018] (III) Beneficial Effects

[0019] This invention proposes a register chip data destruction system for power-free environments. By designing a destruction trigger and the tip of the register chip, this invention enables the destruction of internal data via self-excited electrical pulses. This invention saves the labor costs associated with periodically replacing the built-in small backup battery, and the device requires no maintenance. In the absence of power, it can rapidly generate self-excited electrical pulses to destroy the internal data of the register chip.

[0020] This type of device can be miniaturized and mass-produced. Attached Figure Description

[0031] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0032] This invention uses a method that does not require a small backup battery to destroy the data inside the register chip through self-excited electrical pulses.

[0033] This invention provides a register chip data destruction system for a power-free environment. The system includes: a register chip, printed circuit board lines, wires, and a destruction trigger. The destruction trigger includes: a conductive terminal, a piezoelectric ceramic, a pad, a hammer, a compression spring, and a housing.

[0034] The register chip, located on the circuit board, has a pointed tip at the position where its chip pin printed line aligns with the printed line on the circuit board;

[0035] The printed circuit line is located on the circuit board, with one end aligned with the tip and the other end connected to the wire.

[0036] One end of the wire is connected to the printed line on the circuit board, and the other end is connected to the conductive terminal of the destroy trigger.

[0037] Conductive terminal: Made of copper, it has good conductivity. One end extends out of the through hole on the first end face of the outer shell and is connected to the wire. The other end is connected to the piezoelectric ceramic, serving as the discharge terminal of the piezoelectric ceramic and also acting as a sealing and destroying device.

[0038] Piezoelectric ceramics: One end of a piezoelectric ceramic is connected to a conductive terminal, and the other end is connected to a gasket. When compressed, it generates high-voltage electrical energy.

[0039] Gasket: Made of copper, it has good conductivity and serves as a conductive terminal for the piezoelectric ceramic. It also disperses the force of the hammer impacting the piezoelectric ceramic, ensuring that the pressure is evenly distributed and transmitted to the piezoelectric ceramic, preventing the piezoelectric ceramic from shattering after localized impact.

[0040] Hammer body: made of aluminum, including: hammer head, cylindrical rod, and pull ring. A gap is provided between one side of the hammer head and the pad for impacting the piezoelectric ceramic pad. The cylindrical rod is fixedly connected to the other side. The cylindrical rod passes through a through hole on the second end face of the outer casing and connects to the pull ring. See details. Figure 5 A pre-formed indentation is provided in the middle of the cylindrical rod, which forms a weak point. This pre-formed indentation is located inside the outer shell.

[0041] Compression spring: made of stainless steel, fitted inside the cylindrical rod within the housing, compressed and released to cause the hammer to strike the piezoelectric ceramic.

[0042] Outer shell: Plastic or metal shell, hollowed out in the middle, with through holes on both ends.

[0043] Example 1:

[0044] The workflow of the technical solution of this invention.

[0045] (1) The initial state of the destruction system is as follows: Figure 1 As shown, the initial state of the destroy trigger is as follows: Figure 6 As shown.

[0046] (2) When an emergency occurs and the data in the register chip needs to be destroyed, the hammer body is pulled out of the housing by applying a pulling force to the pull ring of the destruction trigger hammer body. Figure 7 As shown.

[0047] (3) When the tensile force applied to the pull ring exceeds the fracture threshold that the pre-made indentation can withstand, it will break at the pre-made indentation. Figure 8 As shown. The broken pull ring can be taken back by the person responsible for destruction as evidence that the equipment has been destroyed. A serial number can be stamped on the pull ring for accurate identification of the object to be destroyed.

[0048] (4) The hammer of the destroyer strikes the piezoelectric ceramic to generate high voltage, which is transmitted to the printed circuit board lines via wires, such as... Figure 9 As shown.

[0049] (5) A tip discharge gap is designed between the printed lines of the circuit board and the printed lines of the chip pins, such as... Figure 10 As shown, high voltage can break down the air, discharge the chip pins, and cause the chip to break down, resulting in internal data corruption or permanent melting, which in turn leads to incorrect data being read or the chip becoming unusable.

[0050] The voltage generated by impacting the piezoelectric ceramic can be controlled by preset spring force. When the spring force is low, the generated voltage is low and the chip data is disturbed. When the spring force is high, the generated voltage is high and the chip is melted.

[0051] Using a discharge gap method can avoid the impact of destroying the system on the use of the original circuit.

[0052] This invention, through the design of a destroy trigger and the tip of the register chip, enables the destruction of data within the register chip via a self-excited electrical pulse. This invention saves on the labor costs of periodically replacing the built-in small backup battery, and the device requires no maintenance. Even in the absence of power, it can rapidly generate a self-excited electrical pulse to destroy the data within the register chip.

[0053] This type of device can be miniaturized and mass-produced.

[0054] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
