Description

Technical Field

[0001] The present invention relates to the field of laser detection technology, and in particular to a launch aiming simulation training system and method. Background Art

[0002] In the laser beam-riding guidance mode, when the aircraft is launched, the laser launch device emits a laser beam to illuminate the target, and the center line of the laser beam coincides with the aiming line. The aircraft enters the laser beam immediately after launch and always keeps flying in the laser beam until it hits the target. In order to achieve the guidance of the aircraft, the laser beam must be spatially frequency encoded to form a laser information field. During the flight of the aircraft, the information receiving device at the tail of the aircraft continuously receives and decodes the laser information, calculates the direction and size of the aircraft's deviation from the center line of the laser beam, and then forms a control instruction to control the aircraft to always fly along the center line of the laser beam.

[0003] During the flight of the aircraft, the shooter must always aim the aiming mark at the target, that is, keep the laser beam shining on the target, so that the aircraft can hit the target accurately. Especially when the target is moving or the line of sight is blocked, high requirements are placed on the shooter's operating skills and psychological quality. The level of the shooter's comprehensive ability directly determines the accuracy of the aircraft's hit. Therefore, how to effectively train and evaluate the shooter has become an important issue in the use of aircraft.

Specifically, the shooter's operating ability level within the platform is evaluated based on the video data, and the shooter's aircraft control ability is evaluated based on the deviation between the simulated training flight trajectory and the aiming line.

[0033] Aircraft may include missiles, artillery shells, rockets, cruise missiles and other real aircraft or corresponding simulated training aircraft. For example, simulated training aircraft are equipment used to simulate the aircraft launch environment. They do not carry real explosives, but only have the same propellant as real aircraft to realize the launch process of real aircraft.

[0034] Compared with the existing technology, the launch and aiming simulation training system provided in this embodiment adopts a launch and aiming simulation training method under conditions close to the actual operation of the platform. By launching a simulation training aircraft, the impact of interference factors such as impact vibration during aircraft launch on the shooter is restored, which can reflect the shooter's ability level in a real aircraft launch environment.

[0035] In the following, reference Figures 1 to 7 , a launch aiming simulation training system according to an embodiment of the present invention is described in detail. Figure 1 The launch and aiming simulation training system includes: laser information field information receiving subsystem, video monitoring subsystem and training evaluation subsystem.

[0036] 1. System composition

[0037] The launch aiming simulation training system is mainly composed of a laser information field information receiving subsystem, a video monitoring subsystem, a training evaluation subsystem, and a simulated training aircraft. The laser information field information receiving subsystem consists of an information receiving device, a receiving device bracket, a background target, a laser information processing and conversion module, and a wireless communication module; the video monitoring subsystem consists of a video acquisition device, a storage device, and accessories; the training evaluation subsystem consists of a wireless communication module, a laptop computer, and training evaluation software. See the product block diagram for details. Figure 1 .

[0038] 2. Working Principle

[0039] In the process of using aircraft (such as missiles) to strike targets, shooters must gradually acquire basic skills, professional skills and comprehensive skills. In order to meet the requirements of aircraft shooting training, according to the actual operation process and key elements, the launch aiming simulation training system conducts operation training and result evaluation for shooters in two aspects: platform operation and aircraft control. The workflow is as follows: Figure 2 shown.

[0040] In the platform operation link, the shooter needs to complete a series of operation tasks independently or together with other personnel in the operation platform, including computer startup, startup and adjustment of the observation sight, guidance information field calibration, launch control system startup, shooting preparation, aircraft shooting, etc. In this process, the shooter is required to complete each step according to the established operation process, and it is necessary to assess the correctness and standardization of the shooter's operation process and the fluency of his or her action essentials. In order to achieve the assessment indicators, the system adopts the method of real-time video monitoring, and installs a video acquisition device at a suitable position in the operation platform by means of a suction cup or magnet. The video acquisition device records the shooter's operation process in high-definition video and stores it in the storage device.

[0041] In the aiming and control link, the shooter needs to participate in the guidance and control of the aircraft throughout the whole process. From the launch of the aircraft into the laser information field, flying in the laser information field until hitting the target, the shooter needs to control the console to make the aiming mark in the sight always aim at the center of the target. Since the aiming line coincides with the center line of the laser information field, when the aiming mark is aimed at the target, it means that the center line of the laser information field is aimed at the target. The aircraft is located in the laser information field during the entire flight phase. The deviation between the aircraft and the center line of the laser information field is obtained by the guidance system on the missile to generate control instructions, and then the flight attitude and flight trajectory of the aircraft are controlled by the steering gear to make the aircraft fly back to the vicinity of the center line. Therefore, the system uses a set of information receiving devices to simulate the laser receiver on the aircraft missile, and places the information receiving device at the center of the target to receive the information of the laser information field, and performs photoelectric conversion and amplification filtering on the received laser signal to obtain a voltage signal that can reflect the energy of the laser information field; then the laser information processing and conversion module is used to solve and condition the voltage signal and convert the analog-to-digital conversion to make the voltage signal easier to process. By acquiring the energy distribution of the laser information field, the operation process of the shooter manipulating the aiming line to aim at the target can be analyzed.

[0042] The above two links cover the entire operation and use process of the aircraft by the shooter. After the operation training data of the shooter is obtained, it is analyzed and evaluated through a set of training evaluation software. The training evaluation software is installed in the laptop computer. The laser information field information receiving subsystem transmits real-time data with the laptop computer through the wireless communication module. After the signal is encrypted, the data is transmitted wirelessly through the MESH mode, and the wireless data receiving component converts it into the network port protocol and sends it to the laptop computer through the network port. The training evaluation software in the laptop computer can automatically complete the processing, analysis and result display of the shooter's training data in the aiming control link. The recorded video of the shooter's operation link in the operating platform is viewed in real time or video playback by the assessment and evaluation personnel, and the shooter's operation ability level is comprehensively judged, and the assessment score is given and entered into the training evaluation software. The training evaluation software integrates the operation training results of the shooter in the two links and automatically gives the training results and ability level.

[0043] 3. Workflow

[0044] 1. According to the training requirements for shooters at different levels, the front personnel place the background target at a certain distance from the operating platform, so that the surface of the background target is perpendicular to the line connecting the operating platform and the background target, and ensure the visibility between the operating platform and the background target.

[0045] 2. Connect the information receiving device, laser information processing and conversion module, and wireless communication module together, and then install them together on the receiving device bracket, and then place them in front of the background target at the cross center line position, so that the information receiving device faces the direction of the operating platform and ensure that the center line of the optical channel is perpendicular to the target surface.

[0046] 3. The rear personnel connect the wireless communication module in the training evaluation subsystem to the laptop computer and place it on one side of the operating platform.

[0047] 4. The front personnel and the rear personnel turn on the equipment switches respectively, and the switch indicator lights up. After the antenna indicators of the wireless communication modules of the laser information field information receiving subsystem and the training evaluation subsystem turn green, the wireless transmission is normal and the system can be connected normally.

[0048] 5. The rear personnel open the training evaluation software on the laptop and confirm that it is running normally. At this time, the system preparation work for the aiming and control link training is completed.

[0049] 6. Install the storage device on the video acquisition device and use accessories to absorb or fix it to the corresponding position in the operating platform to ensure that the video acquisition area can cover all the spaces where the shooter performs the full process operation.

[0050] 7. Place the simulated training aircraft in the pre-launch preparation state of the real aircraft.

[0051] 8. Put the laser information field information receiving subsystem, video monitoring subsystem and training evaluation subsystem into working state, then give instructions to the shooter to start training. The shooter presses the launch button to launch the simulated training aircraft and starts timing at the same time.

[0052] 9. After the shooter completes a complete training session, the launch aiming simulation training system stops collecting data and videos. The training evaluation software analyzes the training results of the aiming control link based on the collected data. The assessment personnel observe the shooter's specific performance in the platform operation link and evaluate the training results based on the shooter's comprehensive performance in the two links.

[0053] IV. Main Components of Launch Aiming Simulation Training System

[0054] The laser information field information receiving subsystem is used to receive the laser information field data in real time and obtain the shooter's actual aiming position at each moment based on the laser information field data, so as to simulate the flight trajectory of the aircraft. The deviation between the flight trajectory of the simulated training aircraft (axis) and the aiming line can reflect the actual situation of the shooter manipulating the laser information field. The deviation signal is transmitted to the data processing terminal and provided to the operating platform, and the operating platform controls the flight attitude and flight trajectory of the simulated training aircraft according to the deviation signal.

[0055] The laser information field information receiving subsystem includes: an information receiving device, a laser information processing and conversion module and a wireless communication module, wherein the information receiving device is used to receive the modulated light signal of the laser information field, convert the light signals of different frequencies into electric pulses of corresponding frequencies and transmit them to the laser information processing and conversion module; the laser information processing and conversion module is used to demodulate the electric pulse signal in real time and continuously to obtain a DC voltage signal at the position of the information receiving device; and the wireless communication module is used to transmit the DC voltage signal to the data processing terminal.

[0056] 1. Information receiving device

[0057] refer to Figure 2 and Figure 3 The information receiving device includes an optical lens, an infrared filter, a photodiode and an amplifying and filtering circuit. The optical lens is used to converge the laser information onto the surface of the infrared filter; the infrared filter is used to perform optical filtering on the converged laser information and then send it to the photosensitive surface of the photodiode; the photodiode is used to convert the filtered laser information into a level pulse signal; and the amplifying and filtering circuit is used to perform amplifying and filtering on the level pulse signal to convert the weak laser signal into an easily identifiable electrical pulse signal.

[0058] Specifically, the function of the information receiving device is to receive the modulated optical signal of the laser information field, and convert the optical signal of different frequencies into electrical pulses of corresponding frequencies, and then transmit the pulse electrical signal to the laser information processing and conversion module, which will demodulate the Uy and Uz DC voltages reflecting the position of the laser receiver in the laser information field in real time and continuously. Figure 3 .

[0059] The working principle of the information receiving device is as follows: the laser information is focused onto the surface of the infrared filter through an optical lens, and then sent to the photosensitive surface of the photodiode after optical filtering by the infrared filter. The photodiode converts the laser information into level pulse information. The connection board completes the connection between the photodiode and the amplification and filtering circuit. The level pulse output by the photodiode is sent to the preamplifier circuit of the amplification and filtering circuit for primary amplification, and then sent to the high-pass filter circuit to filter out the low-frequency components. After secondary amplification, it is sent to the low-pass circuit for tertiary amplification and filtering out the high-frequency components, thereby achieving the purpose of converting weak laser information into an easily recognizable voltage waveform and realizing the circuit frequency domain filtering.

[0060] 2. Laser information processing and conversion module

[0061] refer to Figure 2The laser information processing and conversion module includes a coordinate solution circuit, an energy solution circuit and an analog-to-digital conversion module, wherein the coordinate solution circuit is used to convert the electric pulse signal into a command voltage signal, the command voltage signal includes a voltage signal Uy in the y-axis direction and a voltage signal Uz in the z-axis direction of the information receiving device relative to the optical axis position in the laser signal field; the energy solution circuit is used to convert the electric pulse signal into an energy voltage signal Ue; and the analog-to-digital conversion module is used to convert the voltage signal Uy, the voltage signal Uz and the energy voltage signal Ue into digital signals, encode the digital signals into serial port signals and send them to the wireless communication module.

[0062] Specifically, the function of the coordinate solving circuit is to process the electrical pulse signal output by the information receiving device into two signals Uy and Uz that follow the change of the line deviation amplitude, representing the position of the information receiving device relative to the optical axis in the laser information field.

[0063] refer to Figure 4 The energy solution circuit includes a voltage follower circuit, an absolute value circuit, and an effective value circuit. The voltage follower circuit is used to receive a voltage signal and isolate the received voltage signal from the output voltage signal; the absolute value circuit is used to obtain an absolute value voltage signal of the output voltage signal of the voltage follower circuit; and the effective value circuit is used to obtain the effective value of the absolute value voltage signal to obtain the energy voltage signal Ue.

[0064] The function of the energy calculation circuit is to convert the signal of the information receiving device into the energy signal of the laser information field through a certain transfer function. The circuit schematic diagram is shown in Figure 4 . The energy solution circuit is mainly composed of a voltage follower circuit, an absolute value circuit and an effective value circuit. The voltage signal first enters the voltage follower, and the voltage follower circuit has the characteristics of high input impedance and low output impedance, which is used to isolate the influence between the front and rear stage signals and play a buffer isolation role; then, the absolute value circuit takes the absolute value of the electrical signal to make it a positive signal; then the effective value of the energy voltage signal is read out through the effective value circuit, and finally the signal is output.

[0065] refer to Figure 5 The function of the analog-to-digital conversion module is to convert the signal generated by the energy solution circuit into analog-to-digital, and then generate a serial port signal in TTL format and send it to the wireless communication module. The analog-to-digital conversion module uses the C8051F510 single-chip microcomputer. The analog-to-digital conversion integrated inside the single-chip microcomputer is a 12-bit acquisition system. Its own acquisition accuracy is 0.8 millivolts, and the acquisition accuracy is high. At the same time, the circuit uses a voltage follower to isolate the input and output signals, improve the input impedance, and make the analog-to-digital conversion more accurate. See the circuit schematic diagram Figure 5 .

[0066] 3. Wireless communication module

[0067] The laser information field information receiving subsystem and the training evaluation subsystem use the same wireless communication module, which is mainly composed of a wireless data transmission module, a power module, and a power display module. The main function is to transmit the data detected by the information receiving device to a laptop computer.

[0068] The wireless data transmission module adopts a plug-and-play MESH transmission board, point-to-point transmission mode, and internationally certified encryption method. Its main function is to send TTL serial port signals to a laptop computer wirelessly.

[0069] The power module is divided into a battery and a DC-DC power regulator module. The battery uses a domestically produced low-temperature 18650 lithium battery, with a single battery capacity of 2.5Ah, and a 4-series-2-parallel solution is used to achieve a capacity of 5Ah. The DC-DC power regulator module uses domestically produced TH20W24S-13V and TH20W24D-12V6 to power the equipment, isolate the power input and output, and improve the insulation resistance and dielectric strength of the internal signal and the shell, thereby improving the safety of the equipment.

[0070] The power display module is used to increase human-computer interaction. The operator can grasp the equipment life according to the power indication and plan the training content reasonably. The power display module solution uses F124 to control a full-color common cathode LED. When the power is sufficient, all three-color beads of the full-color LED light are lit; when the power drops to 50%, the blue bead goes out, and the red and green beads are lit; when the power drops to 25%, the blue and green beads go out, and only the red bead is lit; when the power is too low to support the system operation, all three-color beads go out.

[0071] 4. Receiver bracket

[0072] The laser information field information receiving subsystem also includes a background target and a receiving device bracket. The background target is set at a certain distance from the operating platform, so that the target target surface is perpendicular to the line connecting the operating platform and the background target, and the visibility between the operating platform and the background target is guaranteed; the information receiving device, the laser information processing and conversion module and the wireless communication module are electrically connected in sequence and the information receiving device, the laser information processing and conversion module and the wireless communication module are installed together on the receiving device bracket. The receiving device bracket is set at the cross center line position in front of the background target, so that the information receiving device faces the direction of the operating platform, and the center line of the optical channel is guaranteed to be perpendicular to the target surface.

The installation height can be adjusted within the range of 1.5m to 3m. It is retractable and foldable for easy carrying. It is reliably and firmly connected to the information receiving device through a threaded connection.

[0074] 5. Background target

The video monitoring subsystem is adsorbed or fixed to the corresponding position in the operating platform through accessories to ensure that the video acquisition area is sufficient to cover all spaces where the shooter performs the full process operation.

[0078] The video monitoring subsystem uses a high-definition motion camera as a video acquisition device to capture the entire process of the shooter's operation in the operating platform. The captured high-definition video resolution is 1920×1080 and the frame rate is ≥25 frames / second. After the video acquisition is completed, it is recorded and stored through a built-in large-capacity storage device. The storage capacity meets the requirement of continuous storage of high-definition video of not less than 1 hour. The video acquisition device is fixed to an appropriate position in the operating platform by a strong suction cup or magnet according to the specific situation in the operating platform. The system is powered by a battery, has a display screen, can store and play back surveillance video information, and has motion anti-shake function.

[0079] 7. Data processing terminal: The laptop computer uses a domestically produced high-performance laptop.

[0080] 8. Training evaluation software: The training evaluation software is installed and run on a laptop computer. It is the main means of human-computer interaction and is used to analyze and process the shooter's operation training data, evaluate the performance and display the results. It is divided into three levels: device interaction layer, intermediate business layer and user interaction layer. Figure 7 shown.

[0081] The main functions of the training assessment software are: (1) to plan and set up tasks for shooter training programs according to the quality and ability level requirements of three levels: basic skills, professional skills, and comprehensive skills;

[0082] (2) Initially process the aiming operation information of the shooter in the aiming control link collected by the information receiving device and save it as an operation training data file; (3) Analyze and process the shooter's operation training data according to certain evaluation standards and give corresponding training performance scores; (4) For the shooter's operation process in the platform operation link, experts watch the video and score it, and then manually enter the score; (5) Weight the platform operation link and the aiming control link scores to automatically obtain the shooter's comprehensive score; (6) Calculate the shooter's aiming control data throughout the process, draw the flight trajectory of the aircraft, and intuitively display the shooter's aiming control ability on the entire trajectory; (7) Analyze multiple groups of shooter operation training data, draw training data curves, compare multiple shooter training data and compare training data between multiple shooters; (8) It has a training data management function and can display, query, delete and other operations on training data records.

[0083] The training evaluation subsystem is used to receive the video data, evaluate the shooter's operating ability level in the platform based on the video data, and evaluate the shooter's aiming control ability on the full trajectory based on the deviation between the simulated training flight trajectory and the aiming line.

[0084] The training evaluation subsystem is installed in the data processing terminal. The training evaluation subsystem includes: a task planning module, which is used to plan and set up the shooter training project according to the quality and ability level requirements of three levels: basic skills, professional skills and comprehensive skills; an operation training database, which is used to initially process the aiming operation signal of the shooter in the aiming control link collected by the information receiving device and save it in the operation training database; a training scoring module, which is used to analyze and process the shooter's operation training data according to the evaluation criteria and give the corresponding training performance score; an expert scoring module, which is used to manually enter the scores of the shooter's operation process in the platform operation link after the experts watch the video and give the scores (the expert scoring module is used to manually enter the scores of the shooter's operation process in the platform operation link). The system is used to determine whether the shooter's operation process is correct, but it is impossible for experts to score automatically by watching the video transmitted in the platform); the weighting module is used to weight the scores of the platform operation link and the aiming control link to automatically obtain the shooter's comprehensive score; the solution module is used to calculate the aiming control data of the shooter in the whole process, draw the flight trajectory of the aircraft, and intuitively display the shooter's aiming control ability on the whole trajectory. Among them, if the shooter operates the laser information field to always aim at the crosshairs of the static target, the flight trajectory is a straight line, but due to the shooter's aiming deviation and fluctuation, the flight trajectory of the simulated aircraft is a curve. In other words, the deviation signal is generated by the shooter's failure to always aim at the crosshairs. The data curve module is used to analyze multiple groups of shooter operation training data, draw training data curves to compare the shooter's multiple training data and compare the training data between multiple shooters; and the training data management module is used to display, query, and delete the training data records.

[0085] Specifically, basic skills refer to the shooter's ability to successfully complete the basic operations of the launch process of a simulated training aircraft (such as a missile), and to always keep aiming at the target from the time the simulated training aircraft fires from the muzzle until it hits a stationary target. Professional skills refer to adding aiming operations on moving targets on the basis of basic skills. Comprehensive skills refer to the ability to always keep aiming at the target on the basis of professional skills in special circumstances such as short-term fire, smoke, etc. blocking the line of sight, and sudden turns and stops of the target.

[0086] Specifically, (1) refers to allocating the scores of the platform operation link and the aiming control link in a certain proportion, such as 0.4 for the platform operation link and 0.6 for the aiming control link. (2) According to the laser coding information received by the laser receiving device during the entire flight process of the aircraft, the coordinate value at each moment can be obtained, that is, the deviation from the laser axis, and then the flight trajectory can be drawn. (3) By comparing multiple groups of different flight trajectories drawn, the scores can be given according to parameters such as the average deviation value, maximum deviation value or deviation value change range of the curve.

[0087] Specifically, based on the laser coding information received by the laser receiving device, the two-dimensional coordinate position corresponding to the shooter's aiming point at each moment can be calculated, thereby obtaining the shooter's aiming control data.

The deviation between the flight trajectory and the aiming line is used to reflect the actual situation of the shooter manipulating the laser information field. Specifically, the actual aiming position of the shooter at each moment is obtained according to the laser information field data to simulate the flight trajectory of the aircraft. In step S802, the video data of the shooter's operation process is captured in the form of high-definition video and stored, wherein the video monitoring subsystem is adsorbed or fixed to the corresponding position in the operating platform through accessories to ensure that the video acquisition area is sufficient to cover all spaces for the shooter to perform full-process operations; and in step S803, the video data is received by the training evaluation subsystem, and the shooter's operating ability level in the platform is evaluated according to the video data, and the shooter's aircraft control ability is evaluated according to the deviation signal.
