Description

Technical Field

[0001] The utility model relates to a moving target system with a sound effect simulation function. Background Art

[0002] Moving targets are a target system currently used by troops for live-fire shooting training. Their characteristics are that they can simulate moving targets such as tanks and vehicles and can carry out more complex tactical training.

[0003] The current moving targets still have the following shortcomings when simulating large moving targets such as tanks and vehicles:

[0004] In actual combat, heavy equipment such as tanks and armored vehicles have thick protective armor, heavy weight, and high engine power. The roar of the engine and the sound of the tracks are very loud during the movement, and can often be heard from several kilometers away. Moving targets usually use unmanned vehicles to add contoured shells to simulate large equipment such as tanks and armored vehicles. Unmanned vehicles are usually converted from trams or ordinary vehicles due to their low weight. The engine sound is very small during the movement and can often only be heard within tens of meters. Soldiers participating in live-fire training find it difficult to find targets and conduct live-fire shooting in time, which is very different from the actual battlefield, seriously affecting the training effect.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, and the above and / or other advantages of the present invention will become more clear.

[0029] Figure 2 This is a block diagram of the sound simulator. DETAILED DESCRIPTION

[0030] In this embodiment, Figure 1 The schematic diagram is a composition diagram of a motion target system with a sound effect simulation function, including a motion target 1 and a sound effect simulator 7.

[0031] The moving target 1 includes a moving platform 2, a target body 3, a target detection device 4, a target positioning module 5, and a target information sending communication device 6.

[0032] Taking the simulation object of the moving target 1 as a tank as an example, the moving platform 2 can be an electric platform, and the target body 3 is a simulated shell of the tank shape, which is installed on the moving platform 2. The target detection device 4 can adopt ultrasonic target detection technology, conductive target detection technology, or vibration target detection technology. If the ultrasonic target detection technology is adopted, the target detection device 4 is installed on the moving platform 2, and the hit position is determined by detecting the shock wave of the shell body. Ultrasonic target detection is a commonly used target detection technology and will not be described in detail here. If the conductive target detection technology is adopted, the target detection device 4 is installed on the target body 3, and the hit position is determined by detecting the electrical signal when the shell passes through the target body. Conductive target detection is a commonly used target detection technology and will not be described in detail here. If the vibration target detection technology is adopted, the target detection device 4 is installed on the target body 3, and the hit position is determined by detecting the vibration signal when the shell passes through the target body. Vibration target detection is a commonly used target detection technology and will not be described in detail here.

[0033] The target positioning module 5 may use a Beidou positioning module, a GPS positioning module or other positioning devices to output the geographic coordinate information of the moving target 1 .

[0034] The target information sending communication device 6 can be a wireless communication device such as a general data transmission radio or a 4G communication module, which is used to send out the attribute information of the moving target 1 simulation object, the geographic coordinate information of the moving target 1, or the target detection result information in real time.

[0035] The sound effect simulator 7 is installed on the trainee, and includes a personnel positioning module 8, a sound effect synthesis module 9, a stereo audio playback device 10, a human head posture measurement device 11, and a target information receiving communication device 12.

[0036] The target information receiving communication device 12 can be a communication device of the same model as the target information sending communication device 6 .

[0037] The personnel positioning module 8 may use a Beidou positioning module, a GPS positioning module or other positioning devices to output the geographic coordinate information of the trainees.

[0038] The human head posture measurement device 11 is composed of a microprocessor and a posture sensor. The microprocessor can be an STM32F4 series ARM chip, and the posture sensor can be a nine-axis sensor, such as a MEMS chip such as LSM9DS1. The nine-axis sensor includes a three-axis gyroscope, a three-axis acceleration sensor, and a three-axis magnetic induction sensor. It is a common technology to use a nine-axis sensor to measure the pitch angle, the roll angle, and the angle with the true north of the earth (converted by the magnetic north angle).

[0039] Specifically, in this embodiment, the human head posture measurement device 11 is installed at a fixed position on the top of the head, and can measure the head's pitch angle, roll angle and angle with the earth's true north. The personnel positioning module 8 is installed at a fixed position on the human body, and outputs the geographical coordinate information of the human body in real time.

[0040] The sound effect synthesis module 9 can calculate the distance from the person to the moving target 1 according to the geographic coordinate information of the moving target 1 and the geographic coordinate information of the person; since the positions of the left ear and the right ear of the human body on the head are determined, according to the pitch angle, roll angle and angle data with the true north of the earth, the distance from the person to the moving target 1, and the relative position data between the head posture measurement device 11 and the person positioning module 8 and the left ear and the right ear, the distance from the left ear and the right ear to the moving target 1 can be calculated respectively. The distance data can be obtained through the general trigonometric relationship, and no specific derivation is made here.

[0041] Specifically, in this embodiment, according to the propagation speed of sound, the corresponding sound source is delayed according to the distance between the left ear and the right ear and the moving target 1, so as to simulate the spatial effect of the sound of the simulated object reaching the left ear and the right ear. According to the sound intensity attenuation rate related to the sound intensity and the distance, the volume of the corresponding sound source is adjusted according to the distance between the left ear and the right ear and the moving target 1, so as to simulate the sound intensity effect of the sound of the simulated object reaching the left ear and the right ear. On this basis, the left ear audio stream and the right ear audio stream are synthesized and output to the left channel and the right channel of the stereo audio playback device 10 through the output data interface. The method of synthesizing audio streams is a general technology.

[0042] Specifically, in this embodiment, the microprocessor of the sound effect synthesis module 9 can be an ARM processor. The input data interface can be Bluetooth or RS232 serial port. The output data interface can be Bluetooth or a dual-channel wired output interface. The audio playback device 10 can be a bone conduction headset or a stereo headset.

[0043] The sound effects of the simulated object of the moving target 1 include the engine operation sound, the driving sound, or the hitting explosion sound of the simulated object.

[0044] In this embodiment, the process of the sound effect simulator 7 simulating the engine working sound, or the driving sound, or the hit explosion sound effect is as follows: the moving target 1 sends out the engine working, driving and other related information of its simulation object and the geographical coordinates of the moving target, or the target detection result information through the target information sending communication device 6; after the target information receiving communication device 12 of the sound effect simulator 7 receives the above information, it transmits it to the sound effect synthesis module 9; the sound effect synthesis module 9 selects the engine working sound source, or the driving sound source, or the hit explosion sound source according to the received information, and calculates the distance between the left ear and the right ear and the moving target respectively in combination with the current geographical coordinates, head posture, and the position of the left ear and the right ear on the head of the trainee, and then according to the sound propagation speed and the sound intensity attenuation rate related to the distance, the running sound of the target simulation object is delayed and the volume is adjusted according to the distance of the left ear and the right ear from the moving target, and output to the left channel and the right channel of the stereo audio playback device 10.

[0045] The utility model provides a moving target system with a sound effect simulation function. There are many methods and ways to implement the technical solution. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications should also be regarded as the protection scope of the utility model. All components not specified in this embodiment can be implemented by existing technologies.
