Description
Technical Field
[0001] The utility model belongs to the technical field of self-destruction devices, and particularly relates to a physical self-destruction device for an underwater acoustic signal processor. Background Technique
[0002] At present, with the increasing development and utilization of marine resources, underwater communication has become a key technology in multiple fields such as marine science, military, and civilian use. However, due to the special nature of the underwater environment, traditional radio communication means cannot work effectively underwater, thus giving rise to the development of underwater acoustic communication technology.
[0003] Underwater acoustic communication uses the propagation characteristics of sound waves in water for information transmission, and has the characteristics of low power, long distance, and no need for line of sight. In underwater acoustic communication, the underwater acoustic signal processor plays a crucial role. The underwater acoustic signal processor is mainly responsible for converting the original underwater acoustic signal into an electrical signal that can be processed and analyzed by an electronic system to achieve effective information transmission.
[0004] In the marine environment, the underwater acoustic signal processor may accidentally fall into the hands of the enemy or be illegally obtained, resulting in the leakage of sensitive information or being reverse-engineered and analyzed, thus posing a serious threat to national security or business secrets. Traditional underwater acoustic signal processors lack a fast and effective self-destruction mechanism and cannot destroy sensitive information in time or prevent the device from being used for malicious purposes. Some existing security mechanisms may support remote locking or data erasure, but the response speed is slow, and when the communication link is cut off or the device is physically isolated, there is a lack of direct and rapid remote self-destruction ability. Therefore, based on the special environment of underwater communication and the security requirements for key technologies, as well as the military sensitivity and commercial value of communication technologies, the utility model provides a physical self-destruction device for an underwater acoustic signal processor. Summary of the Utility Model
[0005] To overcome the problems existing in the related technologies, the disclosed embodiments of the utility model provide a physical self-destruction device for an underwater acoustic signal processor.
[0006] The technical solution of the utility model is as follows:

[0008] A self-destruction signal detector, a self-destruction controller, a self-destruction signal transmitter, and a destruction device, and the self-destruction controller is respectively connected to the self-destruction signal detector, the self-destruction controller, the self-destruction signal transmitter, and the destruction device;
[0009] The self-destruction signal detector is connected to the main control circuit of the underwater acoustic signal processor through a connection line. The self-destruction signal transmitter communicates with a remote host computer through a wireless signal. The destruction device is installed outside the main control circuit board and the memory of the underwater acoustic signal processor.
[0010] In one embodiment, the destruction device includes a high-voltage pulse generator and electronic digital detonators.

[0011] In one embodiment, multiple electronic digital detonators are provided, and the multiple electronic digital detonators are arranged at equal intervals on the surface of the main control circuit board.
[0012] In one embodiment, two spaced clamps are sleeved outside the electronic digital detonators. The outer ends of the clamps are integrally connected with clamping heads, and through holes matching the clamping heads are formed on the surface of the circuit board of the underwater acoustic signal processor.
[0013] In one embodiment, the self-destruction controller is connected to a water depth detection device through a connection line, and the water depth detection device is fixedly installed on the outer surface of the underwater acoustic signal processor.
[0014] In one embodiment, the physical self-destruction device of the underwater acoustic signal processor further includes an independent power supply, and the independent power supply is respectively connected to the self-destruction signal detector, the self-destruction controller, the self-destruction signal transmitter, the destruction device and the water depth detection device through connection lines.
[0015] Combining all the above technical solutions, the beneficial effects of the present utility model are as follows:
[0016] With the built-in self-destruction signal detector and self-destruction controller, the present utility model can quickly respond when receiving a self-destruction instruction and start the self-destruction process. Compared with traditional remote locking or data erasure mechanisms, this physical self-destruction method is more direct and rapid. Especially in the case where the communication link is cut off or the device is physically isolated, it can still ensure that sensitive information is not leaked or the device is not maliciously exploited. The destruction device is directly installed outside the main control circuit board and the memory of the underwater acoustic signal processor. Once the self-destruction instruction is activated, it can quickly and effectively damage these key components, fundamentally preventing the recovery of sensitive data or the reuse of the device, providing a higher level of security than simple data erasure. Through the self-destruction signal transmitter, it can communicate with a remote host computer to realize sending a self-destruction instruction remotely, increasing the flexibility and convenience of operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be made with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0024] As Figure 1 shown, the physical self-destruction device of the underwater acoustic signal processor provided by the embodiment of the present utility model includes a self-destruction signal detector 1, a self-destruction controller 2, a self-destruction signal transmitter 3, and a destruction device 4. The self-destruction controller 2 is respectively connected to the self-destruction signal detector 1, the self-destruction signal transmitter 3, and the destruction device 4. The self-destruction signal detector 1 is connected to the main control circuit of the underwater acoustic signal processor through a connection line. The self-destruction signal transmitter 3 is connected to a remote host computer through a wireless signal. The destruction device 4 is installed outside the main control circuit board and the memory of the underwater acoustic signal processor.
[0025] The self-destruction signal detector 1 in the embodiment of the present utility model can be realized by using a common signal acquisition circuit and a signal processing circuit, and an abnormal signal is identified by using preset parameters of the signal processing circuit.
[0026] Preferably, the destruction device 4 in the embodiment of the present utility model includes a high-voltage pulser 41 and an electronic digital detonator 42. The output circuit of the high-voltage pulser 41 is connected to the memory of the underwater acoustic signal processor through a connection line; the electronic digital detonator 42 is installed on the surface of the main control circuit board of the underwater acoustic signal processor.
[0027] In this embodiment, the combination of the high-voltage pulser 41 and the electronic digital detonator 42 is used. The high-voltage pulser 41 directly acts on the memory by outputting high-voltage pulses to physically damage the memory and ensure that sensitive information cannot be recovered. The electronic digital detonator 42 directly destroys key hardware such as the main control circuit board by explosive means to provide more thorough physical damage. This combined use method not only ensures the security at the data level but also ensures the irrecoverability at the hardware level, greatly improving the self-destruction effect.
[0028] Preferably, a plurality of electronic digital detonators 42 are provided in the embodiment of the present utility model, and the plurality of electronic digital detonators 42 are arranged at equal intervals on the surface of the main control circuit board.
[0029] In this embodiment, by arranging a plurality of electronic digital detonators 42 at equal intervals on the surface of the main control circuit board of the underwater acoustic signal processor, it can be ensured that when self-destruction is triggered, the explosion energy can be evenly distributed and effectively cover the entire circuit board area. This layout method not only improves the thoroughness of self-destruction but also reduces the risk of incomplete local damage caused by single-point explosion, enhancing the integrity and reliability of the self-destruction effect.
[0030] Preferably, the self-destruction controller 2 in the embodiment of the present utility model is connected to a water depth detection device 7 through a connection line, and the water depth detection device 7 is fixedly installed on the outer surface of the underwater acoustic signal processor.
[0031] In this embodiment, by fixedly installing the water depth detection device 7 on the outer surface of the underwater acoustic signal processor and connecting it to the self-destruction controller 2, self-destruction triggering based on water depth conditions can be realized. This makes the self-destruction mechanism more intelligent and flexible, and can be adaptively adjusted according to the actual situation of the underwater environment. For example, when the device is illegally salvaged out of the water surface, the water depth detection device 7 can detect the change in water depth and trigger the self-destruction operation, thereby preventing the leakage or malicious use of sensitive information.
[0032] Preferably, the underwater acoustic signal processor provided by the embodiment of the present invention further includes an independent power supply 8, and the independent power supply 8 is respectively connected to the self-destruction signal detector 1, the self-destruction controller 2, the self-destruction signal transmitter 3, the destruction device 4 and the water depth detection device 7 through connection lines.
[0033] In this embodiment, an independent power supply 8 is equipped for the physical self-destruction device of the underwater acoustic signal processor, which can ensure that the self-destruction system can still work normally when the communication link is cut off, improve the independence and reliability of the self-destruction device, and ensure that the self-destruction operation can be carried out quickly and effectively in case of emergency. The independent power supply 8 can also provide stable power support for other key components such as the self-destruction signal detector 1 and the self-destruction controller 2 to ensure the continuous operation of the entire self-destruction system.
[0034] As Figure 2 As shown, two spaced clamps 5 are sleeved outside the electronic digital detonator 42 in the embodiment of the present invention, the outer ends of the clamps 5 are integrally connected with clamping heads 6, and through holes matching the clamping heads 6 are formed on the surface of the circuit board of the underwater acoustic signal processor.
[0035] In this embodiment, the fixing method of the clamp 5 and the clamping head 6 can conveniently install and fix the electronic digital detonator 42 on the surface of the main control circuit board without additional welding or drilling operations, simplify the installation process and reduce the potential damage to the circuit board. At the same time, it also has a certain degree of flexibility, and the position and quantity of the detonators can be adjusted according to needs to meet different self-destruction requirements. In addition, the design of the clamp 5 and the clamping head 6 also ensures the stability of the electronic digital detonator 42 on the circuit board, preventing it from falling off or shifting during the self-destruction process.
[0036] The working principle of the present invention is as follows: When the present invention is in use, the self-destruction signal detector 1 monitors the control signal of the main control circuit of the underwater acoustic signal processor in real time. After detecting an abnormal signal that conforms to the preset parameters, the signal is transmitted to the self-destruction controller 2. The self-destruction controller 2 judges whether to trigger the self-destruction process according to the preset conditions. If a self-destruction operation is required, a self-destruction instruction is sent to the destruction device 4. At the same time, the self-destruction signal transmitter 3 transmits the self-destruction information to the remote host computer through a wireless signal. When it is necessary to actively destroy the underwater acoustic signal processor, the host computer can also actively send a self-destruction instruction to the self-destruction signal transmitter 3, and the self-destruction signal transmitter 3 directly transmits the self-destruction instruction to the self-destruction controller 2.
[0037] The destruction device 4 starts to work. Among them, the high-voltage pulse generator 41 starts first, directly acts on the memory by outputting high-voltage pulses, causing physical damage to ensure that sensitive data cannot be restored. The electronic digital detonator 42 destroys key hardware such as the main control circuit board by explosive means to achieve more thorough physical destruction.
[0038] Under normal operating conditions, the self-destruction device is in a dormant state and will not affect the performance of the device. After receiving a specific trigger signal (such as an abnormal signal), the self-destruction device will quickly start and complete the self-destruction process, ensuring the rapid destruction of the device in case of an emergency and protecting the device and information security.
[0039] In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0040] The above is only a relatively preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto.
