Description

Technical Field

[0001] The present invention belongs to the technical field of defense equipment, and in particular relates to an acoustic and optical combined warning denial system and a warning denial method. Background Art

[0002] In recent years, with the increasing demand for security protection, the application of sound and light alarm equipment in various defense fields has become more and more extensive. However, as the use scenarios of equipment change rapidly, the requirements for equipment reliability, modularization, and intelligence are constantly increasing, especially the real-time performance of the system has been more challenged.

[0003] At present, the existing sound and light warning equipment on the market generally adopts a three-level discrete architecture of "perception-decision-strike". Each subsystem operates independently of each other, and there are significant coordination barriers between subsystems, resulting in large system response delays and low strike efficiency. For example, radar or optoelectronic reconnaissance equipment and strong light, strong sound, and high crystal devices are separated into independent systems. After the radar or optoelectronic reconnaissance equipment finds the target, it needs to upload the data to the command and control center for manual analysis and decision-making, and then the operator manually issues instructions to the strong light and strong sound warning device to execute the strike. This process usually requires a delay of about 10 seconds, and within 10 seconds, the target can quickly advance 80-100 meters, causing the system to miss the best deterrent opportunity, seriously affecting the security effect.

[0004] In addition, existing strong light and sound warning devices generally rely on manual setting of strike parameters (such as light intensity, sound frequency, irradiation angle, etc.) when performing strike missions. Faced with dynamically changing threat targets (such as changes in movement speed, direction, and distance), operators need to adjust parameters in real time, which not only has a slow response speed, but is also prone to misjudgment or missed judgment due to human factors, making it difficult to adapt to complex and changing security scenarios. Summary of the invention

[0005] In response to one or more of the above-mentioned defects or improvement needs in the prior art, the present invention provides an acoustic and visual combined warning denial system, which can shorten the response time of sensing the strike and improve the ability to strike the target.

[0006] To achieve the above-mentioned purpose, one aspect of the present invention provides an acoustic and optical joint warning and rejection system, which is linked with an external perception system and includes a control terminal, a strong light module, a strong sound module and a servo pan / tilt;

[0007] The control terminal is used to receive dynamic target information perceived by the external perception system, and the control terminal is respectively connected to the servo gimbal, the strong light module and the strong sound module for communication;

[0008] The strong light module includes a ranging component and a light emitting component. The ranging component is used to measure the real-time distance between a dynamic target and the strong light module, and the light emitting component is used to emit a light spot and can control the strong light module to adjust the light spot area according to the distance value measured by the ranging component;

[0009] The strong sound module is used to emit warning sound waves;

[0010] Both the strong light module and the strong sound module are connected and arranged on the servo pan-tilt. The servo pan-tilt can drive the strong light module and the strong sound module to rotate to lock the dynamic target in real time;

[0011] The control terminal controls the rotation of the servo pan-tilt according to the dynamic target information, and controls the strong sound module and the light emitting component to emit warning sound and light; meanwhile, the ranging component feeds back the distance value to the control terminal, and the control terminal adjusts the light spot area according to this distance value.

[0012] As a further improvement of the present invention, the light emitting component includes a laser unit and a lens unit. The laser unit is used to emit a light source, and the light source forms a light spot and emits through the lens unit; a focusing member is arranged in the lens unit, and the focusing member is communicatively connected with the control terminal to control the focusing member to adjust the focal length of the light source according to the distance value fed back by the ranging component, and further adjust the emitted light spot area so that the light spot area remains constant.

[0013] As a further improvement of the present invention, the laser unit includes an illumination mode, a strong light irradiation mode and a strong light dazzling mode, and the flashing frequency of the strong light dazzling mode is 5 - 10 Hz.

[0014] As a further improvement of the present invention, the ranging module includes a pulsed laser rangefinder, and the measurable distance range is 20 - 1000 meters.

[0015] As a further improvement of the present invention, the strong sound module includes a sound generating component and a directional sound wave emitting component; the sound generating component includes a sound generating unit and a strong sound control board. The sound generating unit is connected to the strong sound control board, and the strong sound control board is communicatively connected with the control terminal. The strong sound control board processes and converts the electrical signal sent by the control terminal and controls the sound generating unit to emit corresponding warning sound waves; the directional sound wave emitting component emits and propagates the warning sound waves in a directional manner.

[0016] As a further improvement of the present invention, the warning sound waves emitted by the strong sound module include a warning broadcast and a sine warning sound wave, and the warning broadcast is a real-time broadcast for operators or a pre-recorded audio broadcast.

[0017] As a further improvement of the present invention, the sound pressure level of the high-intensity sound module at a distance of 1 m in the front is ≥140 dB, and the sound wave action distance is ≥250 m.

[0018] As a further improvement of the present invention, the high-intensity sound module and the high-intensity light module are separately arranged on both sides of the servo pan-tilt head.

[0019] As a further improvement of the present invention, the rotation module includes a horizontal rotation unit and a pitch rotation unit. The rotatable angle of the horizontal rotation unit is 0° to 360°, and the rotatable angle of the pitch rotation unit is -25° to 50°.

[0020] Another aspect of the present invention provides a border defense acoustic-optical combined warning and deterrence method, which uses the above-mentioned acoustic-optical combined warning and deterrence system to perform warning and deterrence on moving targets. It is characterized by including the following steps:

[0021] (1) The external perception system detects a moving target at a certain distance from the border line and approaching at a certain speed, and determines it as an illegal crossing target; the external perception system feeds back the real-time coordinates, speed and azimuth angle information of the moving target to the control terminal.

[0022] (2) The control terminal controls the servo pan-tilt head to lock the target according to the received moving target information, and controls the high-intensity sound module to continuously emit a warning broadcast.

[0023] (3) If the target withdraws, the warning is stopped; if the high-intensity sound module continuously emits a warning broadcast for a period of time and the moving target does not stop approaching, the control terminal controls the high-intensity light module to emit a warning light spot, and controls the high-intensity sound module to play an audio of a sine warning sound wave to cause discomfort to the moving target until the moving target withdraws.

[0024] The above-mentioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0025] Generally speaking, compared with the prior art, the beneficial effects of the above technical solutions conceived by the present invention include:

[0026] (1) The acoustic-optical combined warning and deterrence system of the present invention separates the high-intensity light module and the high-intensity sound module, which is convenient for modular production of products. By connecting each module to the control terminal at the same time and controlling each module to automatically adjust parameters through the control terminal, a perception-strike direct connection channel is realized, eliminating the time for manual parameter adjustment in the traditional architecture, shortening the response time, and effectively improving the interception success rate of fast-moving targets; at the same time, by setting a ranging component in the high-intensity light module to automatically adjust the lens focal length in real time according to the change of the target distance value, the problem of spot diffusion caused by target movement is overcome, and the effectiveness of spot deterrence is improved.

[0038] Embodiment:

[0039] Please refer to Figures 1 to 4 , the combined acoustic and optical warning and deterrence system in the preferred embodiment of the present invention includes a strong light module 1, a servo pan-tilt 2, a strong sound module 3, and a control terminal 4. Among them, the strong light module 1, the servo pan-tilt 2, and the strong sound module 3 are respectively connected to the control terminal 4, so as to control the servo pan-tilt 2, the strong light module 1, and the strong sound module 3 to jointly warn and strike dynamic targets according to the target information sensed by the external perception module through the control terminal 4, effectively improving the effectiveness and accuracy of dynamic target strikes.

[0040] Specifically, the combined acoustic and optical warning and deterrence system in the embodiment of the present invention is carried on a patrol vehicle to patrol a defense area. Among them, the external perception system is arranged outside the vehicle and is used to monitor the defense area in real time. It has its own algorithm to identify the target type and movement trajectory through the algorithm; at the same time, the external perception system is communicatively connected to the control terminal 4 through Ethernet to transmit target information such as the coordinates, speed, and azimuth angle of the identified target to the control terminal 4.

[0041] In actual setting, the external perception module may include visible light detection devices to perceive and detect the environment in sufficient light, or may include infrared night vision detection devices to perceive and detect the environment in a dark environment. Of course, visible light detection devices and infrared night vision detection devices can also be installed in the external perception module at the same time to achieve the all-weather continuous detection ability of the external perception module.

[0042] Further, as Figure 1 shown, the servo pan-tilt head 2 in the preferred embodiment includes a horizontal rotation unit and a pitch rotation unit. Among them, the horizontal rotation unit can rotate horizontally by 360°, and the pitch rotation unit can rotate pitch by -25 to 50°.

[0043] At the same time, the servo pan-tilt head 2 is communicatively connected to the control terminal 4 through Ethernet. The control terminal 4 controls the servo pan-tilt head 2 to rotate with the dynamic target position according to the target information fed back by the external perception system, and locks the target in real time.

[0044] Further, as Figure 1 shown, the strong light module 1 in the preferred embodiment is fixedly connected and arranged on one side of the servo pan-tilt head 2 to drive the strong light module 1 to lock the target through the servo pan-tilt head 2, and is communicatively connected to the control terminal 4 through Ethernet to control the strong light module 1 to perform strong light warning and rejection on the target through the control terminal 4.

[0045] Specifically, as Figure 3 shown, the strong light module 1 includes a ranging component 101 and a light emitting component; among them, the ranging component 101 includes a pulsed laser rangefinder for measuring the real-time distance between the dynamic target and the strong light module 1, with a ranging accuracy of ±1 m and a measuring range of 20 to 1000 m; at the same time, the ranging component 101 is communicatively connected to the control terminal 4 to feed back the distance value of the dynamic target to the control terminal 4 in real time. The control terminal 4 controls the servo pan-tilt head 2 to adjust the irradiation angle of the strong light module 1 according to this distance value, so that the light spot emitted by the light emitting component always follows the movement of the dynamic target.

[0046] Preferably, the light emitting component includes a laser unit 103 and a lens unit 102. Among them, the laser unit 103 is used to generate and emit light sources, and the light sources are emitted in the form of light spots through the lens unit 102. At the same time, a focusing member is arranged in the lens unit 102, and the focusing member is communicatively connected to the control terminal 4 to control the focusing member to dynamically adjust the focal length of the light source in real time according to the distance value fed back by the ranging component 101, ensuring that within the range of 20 to 250 m, the area of the light spot remains constant when following the target movement. For example, during the movement of the dynamic target, the diameter of the light spot emitted by the strong light module 1 to the target is maintained at 1.5 m.

[0047] In actual settings, the modes of light source emitted by the laser unit 103 include illumination mode, strong light irradiation mode and strong light glare mode, so as to adjust the relevant parameters of the laser unit 103 according to the needs and switch the light emission mode. For the strong light glare mode, a glare linkage algorithm can be set in the control terminal 4 to control the parameters of the strong light glare mode, wherein the flashing frequency of the strong light glare mode is 5 to 10 Hz, so as to achieve a deterrent effect without causing substantial physiological damage to the target.

[0048] Furthermore, if Figure 1 As shown in the figure, the strong sound module 3 in the preferred embodiment is fixedly connected to the servo pan-tilt platform 2, and is preferably arranged on the side of the servo pan-tilt platform 2 away from the strong light module 1. It is communicatively connected with the control terminal 4 to emit an alarm sound wave under the control of the control terminal 4.

[0049] Preferably, the strong sound module 3 includes a sound-generating component and a directional sound wave emitting component, wherein the sound-generating component includes a sound-generating unit 301 and a strong sound control panel 302. Figure 2 As shown in the figure, the sound unit 301 is connected to the strong sound control board 302, and the strong sound control board 302 is connected to the control terminal 4 for communication, so that the electrical signal emitted by the control terminal 4 is processed and converted through the strong sound control board 302, and the sound unit 301 is controlled to emit a corresponding alarm sound wave, and the alarm sound wave is directionally emitted and propagated by using a directional sound wave emission component.

[0050] In actual settings, the alarm sound waves emitted by the sound unit 301 include warning broadcasts and sinusoidal alarm sound waves, wherein the warning broadcast can be a warning prompt broadcast when the target is initially discovered. The warning prompt can be a real-time broadcast for relevant operators, such as direct shouting, fixed shouting, and translated shouting through a microphone, or it can be a broadcast of a pre-recorded audio file stored in the control terminal 4, and the warning broadcast is preferably a multi-language warning broadcast, such as Chinese, English, and the corresponding language of the actual border country.

[0051] Correspondingly, when the target continues to approach after hearing the warning, the control terminal 4 controls the strong sound module to switch to a sinusoidal warning sound wave, causing discomfort to the target and expelling it.

[0052] Preferably, the sound pressure level of the strong sound module 3 at 1 m from the front is ≥ 140 dB, and the sound wave action distance is ≥ 250 meters, so as to effectively deter the target through sound waves.

[0053] Preferably, the control terminal 4 also has a built-in self-checking program, and can start the self-checking mode regularly to control each module in the system to perform self-checking.

[0054] When patrolling the defense area, the above system can be installed on the roof of the patrol car and combined with the vehicle-mounted external sensing system.

[0055] Furthermore, the present invention also includes an acoustic-optical combined warning and deterrence method, which is executed by using the above-mentioned acoustic-optical combined warning and deterrence system, and specifically includes the following steps:

[0056] (1) The external perception system detects a moving target at a certain distance from the border line and approaching at a certain speed, and determines it as an illegal border-crossing target; the external perception system feeds back the real-time coordinates, speed and azimuth angle information of the moving target to the control terminal 4;

[0057] (2) The control terminal 4 controls the servo pan-tilt 2 to lock the target according to the received moving target information, and controls the strong sound module 3 to continuously emit multilingual warning broadcasts;

[0058] (3) If the target withdraws, the warning is stopped; if the strong sound module 3 continuously emits warning broadcasts for a period of time and the moving target still continues to approach, the control terminal 4 controls the strong light module 1 to start the dazzling mode, emit warning dazzling light spots, and controls the strong sound module 3 to play an audio of a sine warning sound wave to cause discomfort to the moving target until the moving target withdraws.

[0059] Those skilled in the art can easily understand that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
