Description

Technical Field

[0001] This invention relates to the field of military training equipment, and in particular to an artillery simulation training device, system, and simulation training method. Background Technology

[0002] Currently, live-fire combat training is developing towards intelligence. Direct-fire weapons often use lasers instead of ammunition for live-fire combat training. Specifically, laser transmitters are mounted on the weapons, and laser decoding devices are installed on personnel and equipment. During combat training, the weapon emits coded laser beams; if the laser decoding devices on personnel and equipment receive the coded laser beams, they are considered to have been hit. Indirect-fire weapons typically use data-driven methods for live-fire combat training. The control center calculates the impact point of the shells based on the artillery's firing data and makes decisions regarding personnel and equipment within the damage range.

[0003] Currently, artillery simulators used for live-fire combat training typically measure the azimuth and elevation angles of artillery by attaching tilt sensors and Beidou direction-finding modules to the barrel of actual artillery. They also obtain firing data such as propellant temperature and propellant charge by manually inputting these data to calculate the trajectory and trajectory of the projectile.

[0004] The above-mentioned approach has the following drawbacks and shortcomings: High-precision sensors are very expensive. If a low-cost BeiDou direction-finding module is used for direction finding, the measurement accuracy is one order of magnitude lower than that of a north-finding instrument, and it is easily affected by environmental interference, leading to a decrease in measurement accuracy. Furthermore, there is the issue of installation accuracy. External sensors can only be installed on the gun barrel. Since the gun barrel is circular and the diameters of the front and rear sections are different, the direction and angle of fire measured by the sensor installed on the barrel are not consistent with the central axis of the barrel, requiring calibration, which also introduces some error. Therefore, the measurement accuracy of external sensors cannot reach that of the artillery fire control system. Calibration during firing would consume a significant amount of time, affecting the rapid movement of the artillery, position deployment, firing, and relocation, thus significantly impacting the training process and results.

[0005] The military has now equipped a large number of self-propelled artillery pieces with fire control systems. These systems are equipped with advanced equipment such as high-precision Beidou positioning, north-finding instruments, gyroscopes, accelerometers, and temperature sensors. They can also receive firing commands from the command and control system and automatically control the firing direction and angle of the artillery barrel, thus enabling rapid movement, deployment, firing, and relocation of the artillery.

[0006] Ideally, firing data should be read directly from the actual fire control system. This would allow for high-precision data consistent with the actual system for ballistic calculations and reduce sensor costs. However, due to the high level of secrecy surrounding weapon systems, some equipment lacks external data interfaces, while others, though possessing them, do not have them publicly accessible. Manufacturers of live-fire training equipment are typically not the equipment manufacturers and cannot access data interface definitions and parameters. Even if some manufacturers can obtain data for certain equipment, the wide variety of artillery models and the varying hardware and data information for each type necessitate the design of dedicated interfaces and software for each, resulting in limited versatility. Furthermore, direct connection to the actual fire control system means that damage to external hardware could damage the system itself, leading to uncontrolled barrel movement, severe equipment damage, and personal injury. Summary of the Invention

[0007] Objective of the Invention: The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing an artillery simulation training device, system, and simulation training method. Utilizing the information display function of a live self-propelled artillery piece, an image information displayed on the fire control system screen is acquired in real time during artillery firing by adding a camera. The firing data recognition device identifies and analyzes the relevant firing data information in the image to obtain firing data such as the firing direction and angle. The firing data information is uploaded to the control center via a communication system. The control center, based on the artillery's ballistic model, firing data, and a geographic information system, calculates the impact point of the shell and performs simulated damage assessment of surrounding targets.

[0008] This invention proposes an artillery simulation training device, system, and simulation training method, which are achieved through the following technical means:

[0009] A type of artillery simulation training equipment includes an artillery firing data identification device, a camera, a firing signal acquisition module, and a communication module;

[0010] The camera, firing signal acquisition module and artillery firing data identification device are electrically connected, and the artillery firing data identification device is electrically connected to the communication module.

[0011] The camera is used to capture images displayed on the screen of the actual fire control system;

[0012] The firing signal acquisition module is used to acquire firing signals during actual artillery firing. The artillery firing data recognition device is a microprocessor for image recognition. After receiving the firing signal from the firing signal acquisition module, it records the image at the current moment and identifies and parses the firing data names and values ​​in the image.

[0013] The communication module is used to receive the firing data identified by the artillery firing data identification device and send it to the control center.

[0014] If the artillery firing data identification device can analyze the firing signal of the artillery through image recognition, then it does not need to include a separate firing signal acquisition module.

[0015] The camera is aimed at the screen of the fire control system, and its field of view can cover the entire screen.

[0016] The firing signal acquisition module acquires the firing signal of the artillery by installing a sensor on the firing mechanism of the artillery; if the firing status can be displayed on the screen of the fire control system, the artillery firing data recognition device can analyze the firing signal of the artillery through image recognition, and at this time it is not necessary to include a separate firing signal acquisition module.

[0017] The present invention also provides an artillery simulation training system, including artillery simulation training equipment, a communication system and a control center, wherein the communication system is used for data communication between the artillery simulation training equipment and the control center.

[0018] The present invention also provides a simulation training method for an artillery simulation training system, comprising the following steps:

[0019] Step 1: Install a gun firing data identification device, a camera, a firing signal acquisition module, and a communication module on the actual artillery. Switch the information display screen of the actual fire control system to the firing data display interface. Point the camera at the screen of the fire control system to take real-time pictures and send the image data to the gun firing data identification device in real time.

[0020] Step 2: After the firing signal acquisition module acquires the firing signal of the artillery, it sends the firing information to the artillery firing data identification device, which then locks the image data at the time of firing.

[0021] Step 3: The artillery firing data identification device identifies keywords related to firing data in the locked image data, parses out the numbers and text following each keyword, converts the numbers into floating-point numbers, and converts the text into standard text encoding, thus completing the acquisition of firing data.

[0022] Step 4: The artillery firing data identification device sends the firing data to the control center through the communication system; the data includes the type of artillery, artillery coordinates, firing direction, firing angle, ammunition type, propellant number, propellant temperature, or target coordinates;

[0023] Step 5: The control center calculates the impact coordinates of the shell based on the artillery's firing data, combined with the 3D map and the artillery's ballistic model. It also calculates the kill radius and damage effect on the target based on the shell's explosive power. If there is a target within the kill radius, the damage assessment is made based on the damage effect.

[0024] The present invention has the following beneficial effects:

[0025] (1) By installing a gun firing data identification device and a camera on the actual artillery, the firing data of the artillery can be identified by image recognition. On the one hand, high-precision data that is completely consistent with the actual equipment can be obtained for ballistic calculation, and on the other hand, the cost of sensors can be effectively reduced.

[0026] (2) It effectively solves the defects of the original external sensor method, such as low measurement accuracy, the need for calibration before firing, and the impact on the rapid movement of artillery, the deployment of positions, firing and relocation, making the confrontation training closer to actual combat.

[0034] The firing signal acquisition module 5 acquires the firing signal of the actual artillery firing by installing a sensor on the firing mechanism. The sensor can be a mechanical switch; when a soldier pulls the firing handle of the actual artillery, the mechanical switch activates and outputs a firing signal. Alternatively, the sensor can be a vibration sensor or an acoustic sensor; when the firing pin of the artillery fires, the vibration sensor or acoustic sensor collects the vibration or sound signal and outputs the firing signal.

[0042] 2) After the firing signal acquisition module 5 acquires the firing signal of the cannon, it sends the firing information to the cannon firing data identification device 3, and the cannon firing data identification device 3 locks the image data at the time of firing.

[0043] 3) The artillery firing data identification device 3 identifies keywords related to firing data in the locked image data, and parses out the numbers and text following each keyword, converting the numbers into floating-point numbers and the text into standard text encoding, thus completing the acquisition of firing data data.

[0044] 4) The artillery firing data identification device 3 transmits firing data such as artillery type, artillery coordinates, firing direction, firing angle, ammunition type, propellant number, propellant temperature, or target coordinates to the control center 6 through the communication system 4.

[0045] 5) The control center 6 calculates the impact coordinates of the shell based on the firing data of the artillery, combined with the three-dimensional map and the ballistic model of the artillery, and calculates the kill radius and damage effect on the target based on the explosive power of the shell; if there is a target within the kill radius, the target is damaged or destroyed based on the damage effect.
