Description

Technical Field

[0001] The invention relates to a simulation confrontation device, in particular to a laser battle simulation confrontation training device. The invention also discloses a training method for the confrontation training device. Background Art

[0002] Nowadays, laser simulation confrontation training is gradually promoted in conventional confrontation training. The use of simulated confrontation can effectively reduce casualties caused by accidents in live ammunition confrontation. The data acquisition of simulated confrontation is simple, no manual verification is required, and its accuracy is also good. Laser confrontation is generally used in tank simulation battles, that is, laser emission and receiving devices are installed on the tank vehicles of both warring parties, a laser transmitter is installed on the gun barrel, and a group of laser receiving probes are installed on the vehicle body, or multiple probes are installed on the vehicle body to form a laser receiving array. When the shooting party fires the artillery, the laser transmitter on the gun barrel can emit a beam of laser to simulate the shooting of the artillery shell. If the laser beam irradiates the target and the probe of the target receives the laser accordingly, it means that the target is hit. If there are signals in several directions or several parts of the probe group, the hit part can be roughly calculated. If a high-precision hit position is required, an extremely fine laser beam should be emitted, and a high-density probe array should be arranged around the tank body, but such a method is obviously very costly and difficult to install and use.

[0003] With the increasing requirements for the realism of combat effects and the accuracy of damage in actual combat training, the original rough hit accuracy can no longer meet the needs, and there is an urgent need for a laser confrontation training device that can achieve high precision.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0027] The present invention relates to a simulation confrontation device, specifically, a combat tank simulation shooting confrontation device, the confrontation device comprises a laser transmitter and receiver and a receiving terminal, the laser transmitter and receiver is arranged on the gun barrel of the combat tank, specifically, the laser transmitter and receiver is arranged at the front end of the gun barrel of the combat tank, the route of its laser emission is consistent with the route of the actual shell emission, the receiving terminal is arranged on the body of the combat tank, and is used to receive the laser emitted by another combat tank, that is, the hit signal of the simulated shell, so as to determine the damage of the body itself and achieve the purpose of confrontation training.

[0028] Specifically, the laser transmitter and receiver includes a laser emitting lens barrel, a laser receiving lens barrel, a shell and a clamp. The bottom of the shell is provided with a clamp, and the clamp is used to firmly fix the shell and the barrel so that the shell will not tilt or even fall when the tank turret swings. In the containing space formed by the shell, a laser emitting lens barrel and a laser receiving lens barrel are provided. The emitting end of the laser emitting lens barrel and the receiving end of the laser receiving lens barrel are provided in the same direction, and the axes of the laser emitting lens barrel and the laser receiving lens barrel are provided in parallel with each other. The laser emitting lens barrel and the laser receiving lens barrel can be provided in the shell left and right, up and down, or obliquely. The two can be provided close to each other or with a gap. The present invention preferably provides that the laser emitting lens barrel and the laser receiving lens barrel are provided close to each other left and right, so as to minimize the width and height of the shell and maximize the saving of manufacturing costs.

[0029] The receiving terminal includes a box, a processing circuit module, a reflecting prism, a laser receiving probe, a satellite positioning module and a vehicle body pointing sensor. The processing module, the satellite positioning module and the vehicle body pointing sensor are arranged in the box, and a column is arranged on the top of the box. The column is cylindrical. On the side of the column, a laser receiving probe and a reflecting prism are arranged. Furthermore, the laser receiving probe and the reflecting prism are arranged in groups, and several groups of laser receiving probes and reflecting prisms are closely arranged around the side of the column, so that the laser incident from any angle can be captured by the laser receiving probe and the reflecting prism, ensuring the normal progress of the confrontation training.

[0030] In the present invention, the reflecting prism adopts a corner cube prism, which has the characteristic of original reflection, that is, the reflected light beam is parallel to the incident light beam, and the incident light coming from any spatial direction has the characteristic of returning along the original path. The use of this kind of prism can effectively reflect the incoming laser back along the original path for processing, and the prism has low reflection loss and high reflected laser energy intensity.

[0031] The present invention also includes a codec, which is connected to the laser emitting lens barrel and the laser receiving lens barrel. The codec decodes the signal received by the laser receiving lens barrel, and then encodes the processed signal and sends it out from the laser emitting lens barrel.

[0032] The present invention also discloses a training method of the laser confrontation training device. First, the present invention sets a laser transmitter and receiver and a receiving terminal on each combat tank. The present invention uses a shooting process as a step description. In the process, a combat tank implements a simulated attack on another combat tank. The combat tank that implements the simulated attack is recorded as a combat vehicle of the shooting party, and the combat tank that receives the simulated attack is recorded as a combat vehicle of the target party. The training method includes the following technical steps:

[0033] First, the shooting vehicle transmits a laser signal to the target vehicle through the laser transmitting lens. The laser signal is transmitted toward the body of the target vehicle. Then, the reflecting prism arranged on the receiving terminal of the target vehicle reflects part of the laser signal emitted by the shooting vehicle back to the shooting vehicle, and the laser signal is received by the laser receiving lens.

[0034] In the present invention, since the reflective prisms are arranged on the pillars, their number must be limited under the control of cost. If conventional lasers are used, it is very likely that they cannot be reflected by the reflective prisms. Therefore, the laser used in the present invention is a laser beam with a large divergence angle, and the laser beam can completely cover the target and the reflective prism. At the same time, each reflective prism can reflect the laser from the front within an angle range of 60°. The combination of six prisms can meet the laser reflection from 360° around without any gaps, such as Figure 3 This ensures that at least one reflecting prism on the column can be completely covered by the laser beam, thus achieving good reflection of the laser beam.

[0035] The reflecting prism described in the present invention is a corner cube prism, which has the characteristic of original reflection, that is, the reflected light beam is parallel to the incident light beam, and the incident light from any spatial direction has the characteristic of returning along the original path. This prism can effectively reflect the laser shot by the combat vehicle of the shooting party, and at the same time, the corner cube prism provides sufficient energy intensity so that the long-distance laser receiving lens barrel can effectively receive and process.

[0036] The laser signal received by the laser receiving lens barrel is then sent to the codec, which decodes the information contained in the laser signal, performs distance measurement, angle measurement and other calculations, and encodes the above information, and uses the laser transmitting lens barrel to send the laser information beam again, and the laser information beam is emitted toward the laser receiving probe of the target combat vehicle;

[0037] Specifically, the laser receiving lens barrel in the laser transmitter and receiver is composed of an imaging lens and a two-dimensional photoelectric sensor. The laser points emitted from different distant positions are imaged as a small light spot on the two-dimensional photoelectric sensor through the lens, and the two-dimensional photoelectric sensor can output the two-dimensional position information relative to the center of the imaging surface. The position information can be converted to calculate the two-dimensional deviation angle of the photoelectric relative to the optical axis. At the same time, according to the time of laser emission and the time of reception, the distance between the transmitting combat vehicle and the target combat vehicle is determined. The above information is then encoded through a decoding encoder and then resent to the target combat vehicle.

[0038] More specifically, when shooting, the aiming point is the optical axis point O. By measuring the distance and the deflection angle of the reference reflecting prism, the position dx and dy of the hitting point O relative to the prism can be calculated. The algorithm is as follows: perform two-dimensional angle measurement on the distant reflected light point P, measure the two-direction angles θx and θy of the reflected light point P relative to the optical axis, and measure the shooting distance L based on the time difference of the returning laser.

[0039] Since the position of the optical axis represents the aiming point and the point where the shell lands, once θx, θy and L are measured, the precise position of the optical axis point O can be calculated based on the reflecting prism:

[0040] dx=θx*L

[0041] dy=θy*L.

[0042] Finally, after the laser receiving probe of the target's combat vehicle receives the laser information beam, it decodes it and combines it with its own three-dimensional physical size model to calculate the hit position and then calculate the precise damage result.

[0043] Usually, for a training weapon vehicle, the installation position of its receiving terminal is the same as the designated position, that is, the fixed receiving terminal position, that is, the fixed position of the reflective prism. Therefore, the reflective prism can be used as a reference point to input one's own 3D entity simulation, so as to accurately calculate the position hit by the opponent's "shell" during shooting training.

[0044] In actual confrontation training, the two sides are in a random state. At this time, the target vehicle cannot face the shooting direction, so the direction and posture of the three-dimensional space need to be fully considered. Once the full three-dimensional model of the target vehicle is established, the vehicle's orientation and posture, and the geographic coordinates of the two sides are collected, comprehensive calculations can be performed in the three-dimensional space of the earth to obtain the "shell" hit position and incident angle data.

[0045] The satellite positioning module contained in the receiving terminal can collect and record the geographical locations of the warring parties in real time using longitude and latitude data. Figure 6As shown: the coordinate system EeN is the geodetic coordinate system, the N direction is 0° due north, and the E direction is 90° due east. Using the longitude and latitude data conversion values ​​as coordinates, the shooting party A is (e1, n1), and the target party P is (e2, n2).

[0046] At this time, the shooting direction Li can be obtained as:

[0047] Li = arctan((e2-e1) / (n2-n1))

[0048] The vehicle body pointing sensor can output the direction of the vehicle body in real time. The vehicle body pointing data pt value is obtained through data collection.

[0049] The angle of incidence r of the projectile is:

[0050] r=pt–Li

[0051] In the actual three-dimensional space, a coordinate system PXYZ with the reflecting prism P as the origin is used to establish a solid three-dimensional model of the target vehicle body. According to the incident angle r, angle measurement and distance measurement data, the position data of the impact point O on the vehicle body surface can be further calculated.

[0052] Once the position and angle of incidence data of the vehicle impact point are obtained, accurate target damage results can be obtained after processing and calculation based on the type of "shell" used by the shooter.

[0053] In the present invention, a vehicle body posture sensor may also be installed to measure the directions of the vehicle body and the turret, so that after the turret rotates, the relevant hit points can still be accurately calculated.
