Description

Technical Field

[0001] The present invention relates to the technical field of biomedical engineering, and in particular to a dummy system and method for detecting the harmful effects of infrasound on human body. Background Art

[0002] Infrasound refers to sound waves with a frequency less than 20 Hz (Hertz). Infrasound is not easy to attenuate and is not easily absorbed by water and air. The wavelength of infrasound is often very long, so it can bypass certain large obstacles and diffract. In nature, sea storms, volcanic eruptions, large meteorites, tsunamis, lightning and thunder, waves hitting the shore, whirlpools in the water, turbulence in the air, tornadoes, magnetic storms, auroras, earthquakes, etc. may all be accompanied by the occurrence of infrasound. In human activities, such as nuclear explosions, missile flights, artillery firing, ship sailing, car racing, high-rise buildings and bridges shaking, even blowers, mixers, loudspeakers, etc. can also generate infrasound while making sounds.

[0003] The inherent vibration frequency of the human internal organs is very similar to the frequency of infrasound waves (0.01Hz-20Hz). When the frequency of external infrasound waves is the same as or close to the frequency of internal organs, a resonance state of the human internal organs will be formed, resulting in various adverse reactions, leading to blurred vision, difficulty swallowing, liver dysfunction and other symptoms. In severe cases, there will be numbness of the limbs and a feeling of pressure in the chest. Especially when the inherent vibration frequency in the human abdominal cavity, thoracic cavity and cranial cavity is consistent with the external infrasound frequency, the internal organ system of the human body will be damaged and death will be caused.

[0004] Infrasonic weapons use specific high-power infrasonic wave generating devices to emit high-intensity infrasonic waves, which resonate with human organs, causing them to deform, shift, or even rupture, resulting in casualties.

[0005] At present, infrasound detection has been used to detect sea storms, volcanic eruptions, large meteorites, tsunamis, lightning and thunder, waves hitting the shore, whirlpools in the water, turbulence in the air, tornadoes, magnetic storms, auroras, earthquakes, nuclear explosions, missile flights, artillery firing, ships sailing, cars racing, high-rise buildings, bridge shaking, and transportation pipeline damage.

[0048] The head 1 includes a head skeleton and a head skin covering the outside of the head skeleton. The head skeleton and the head skin are both made of acoustic metamaterials, so that the head 1 has biological properties equivalent to those of the human body. Moreover, acoustic metamaterials are a type of artificially designed composite materials with extraordinary physical properties that natural materials do not have. They can achieve precise and designable control of sound waves and can truly simulate the resonant response of the human head under the action of infrasound waves.

[0049] The trunk 3 includes a trunk skeleton and a trunk skin covering the outside of the trunk skeleton. The trunk skeleton and the trunk skin are both made of acoustic metamaterials, so that the trunk 3 has equivalent biological characteristics of the human body and can also truly simulate the resonance response of the human trunk 3 under the action of infrasound waves. The trunk 3 includes the thoracic cavity, abdominal cavity and pelvic cavity.

[0050] The simulated heart 4 is made of acoustic metamaterials, so that the simulated heart 4 has biological characteristics equivalent to those of the human body, and can also truly simulate the resonance response of the human heart under the action of infrasound waves.

[0051] The simulated lung 5 is made of acoustic metamaterials, so that the simulated lung 5 has biological equivalent characteristics of the human body, and can also truly simulate the resonance response of the human lung under the action of infrasound waves.

[0052] The infrasound detection and collection device can detect the vibration frequency and amplitude of different parts of the dummy body, such as the head, heart, and lungs, under the action of infrasound, so as to analyze the damage results of various tissue parts of the human body under the action of infrasound.

[0053] Specifically, Figure 2 As shown, the infrasound detection and collection device includes an acceleration sensor, a data acquisition module, an infrasound frequency test sensor, an infrasound sound pressure intensity test sensor and a host computer.

[0054] The acceleration sensor is arranged in the dummy body, and is used to measure the vibration frequency and vibration amplitude of the tissue part where the acceleration sensor is installed in the dummy body.

[0055] The acceleration sensor is disposed inside one or more of the head 1 , the torso 3 , the simulated heart 4 and the simulated lung 5 .

[0056] In this embodiment, the acceleration sensor is at least arranged inside the head 1, the simulated heart 4 and the simulated lung 5. The acceleration sensor may also be arranged inside one or more of the chest cavity, the abdominal cavity and the pelvic cavity.

[0057] The data acquisition module is arranged in the dummy body and is electrically connected to the acceleration sensor to receive the data tested by the acceleration sensor. Preferably, the data acquisition module is arranged in the chest cavity.

[0058] The infrasonic frequency test sensor is arranged outside the dummy body and is located in the environment where the dummy body is located. The infrasonic frequency test sensor is used to test the infrasonic frequency in the environment where the dummy body is located.

[0059] The infrasonic sound pressure intensity testing sensor is arranged outside the dummy body and located in the environment where the dummy body is located. The infrasonic sound pressure intensity testing sensor is used to test the infrasonic sound pressure intensity in the environment where the dummy body is located.

[0060] The host computer is electrically connected to the data acquisition module, the infrasonic frequency test sensor and the infrasonic sound pressure intensity test sensor respectively. The host computer can analyze and process the data input by the data acquisition module, and generate corresponding vibration frequency and vibration amplitude, providing reliable reference data for scientific researchers, medical staff, etc.

[0061] The infrasonic wave detection and collection processing device may also include a low-pass filter, which is electrically connected to the data acquisition module, the infrasonic wave frequency test sensor, the infrasonic wave sound pressure intensity test sensor and the host computer respectively. The test data of the acceleration sensor, the test data of the infrasonic wave frequency test sensor, and the test data of the infrasonic wave sound pressure intensity test sensor collected in the data acquisition device are all sent to the host computer after filtering the high-frequency noise through the low-pass filter.

[0063] S1, providing infrasound to the dummy body through an infrasound weapon or an infrasound generator.

The data acquisition module collects the signals detected by each acceleration sensor and transmits them to the host computer.

[0066] S3, the host computer processes the collected signal data to obtain an infrasound signal.

[0067] The host computer processes the collected acceleration sensor signal data to obtain the vibration frequency and vibration amplitude of the tissue part where the acceleration sensor is installed on the dummy body.

F0, L0, F1, K1, F2, K2, F3, K3 ... must contain environmental noise, and cannot be used directly, and data filtering processing is required.

[0069] Specifically, high-frequency noise is filtered out by using the following low-pass filter:

[0070]

[0071] w=2π*f,

[0072] In the above formula, s is the filter input, and f is the filter cutoff frequency. Through this low-pass filter, clear infrasound signals H0, p0, H1, N1, H2, N2, H3, N3... are obtained.

[0073] S4, using the external infrasound information and the vibration information of different tissue parts of the dummy body, pre-train the infrasound damage assessment model.

[0078] b. Mark the vibration information of different tissue parts of the dummy in advance;

[0079] c. Pre-train the infrasound damage assessment model based on the external infrasound information and the vibration information of different tissue parts of the dummy body.

[0080] The artificial intelligence-based pre-trained infrasound damage assessment model is a fuzzy neural network architecture model, and the fuzzy system used can be type I fuzzy, type II fuzzy, type III fuzzy, etc. The neural network used can be a BP neural network or a deep neural network, etc.

[0081] The specific loss function used is:

[0082]

[0083] in, To predict data, is the average value of the vibration frequency and vibration amplitude of different tissue parts of the infrasound test dummy, and y is the vibration frequency and vibration amplitude of different tissue parts of the dummy.

[0084] (2) Test the model. If the prediction accuracy reaches the target value, stop training; otherwise, continue training.

[0085] The above model can predict the vibration frequency and amplitude of different tissue parts of the human body under the influence of infrasound waves, such as: head, heart, lungs, chest cavity, abdomen, pelvis, etc.

[0086] S5, applying the trained infrasound damage assessment model to obtain the impact data of infrasound on various parts of the human body.

[0087] Process such as Figure 5 As shown, the specific steps include:

[0088] (1) The infrasonic frequency test sensor is used to detect the infrasonic frequency in the environment where the dummy body is located and filter it to obtain H0; the infrasonic sound pressure intensity test sensor is used to detect the infrasonic sound pressure intensity value in the environment where the dummy body is located and filter it to obtain p0.

[0089] (2) Using the infrasound damage assessment model obtained in step S4, the damage to different tissues of the human body is predicted, including obtaining the vibration frequency and amplitude of the head, heart, lungs, chest, abdomen, pelvis, etc. of the human body.

[0090] (3) Obtain prediction results and generate a prediction report.
