Description

Technical Field

[0001] The invention relates to the technical field of shooting training simulators, in particular to an automatic shooting detector for an armored vehicle. Background Art

[0002] At present, there are mainly two schemes for target detection of shooting training automatic detectors used by the troops. The first is the hard contact type: an electric needle (push-pin cylindrical electromagnet) is fixed in front of the gun barrel, and the extension and retraction of the electric needle is controlled by the firing button to make it collide with the pressure or capacitance sensor at the target plate, and the shooting hit is judged according to the sensor output signal; the second is a through-beam photoelectric sensor solution, in which a laser transmitter is fixed in front of the gun barrel and a laser receiver is used at the target plate. By controlling the laser emission and collecting the receiver signal changes, the hit situation is judged.

[0003] However, the problem with the related technology is that the hard contact of the first solution can easily cause damage to the target sensor or cause the target plate to overturn; the second solution requires a laser transmitter and multiple receivers. The multiple receivers are placed close to each other, which will cause interference, resulting in two or more receiving signals, making it impossible to judge the shooting results. When used outdoors, the interference is more serious due to the influence of sunlight, etc. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an automatic detection device for armored vehicle shooting, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an armored vehicle shooting automatic detector, including a base, a target mechanism for reflecting shooting signals, a transmission mechanism fixed above the base for driving the target mechanism to move and adjust the position, a firing device for simulating muzzle shooting, and a display control box for controlling the firing device and the transmission mechanism. The target mechanism includes a target plate and a high-precision reflective sheet, the high-precision reflective sheet is adsorbed on the surface of the target plate by a magnet on the surface, an indicator light is built into the inner cavity of the target plate, and a magnetic whiteboard writing board with an envelope target pattern is pasted on one side of the target plate away from the high-precision reflective sheet. The training personnel The training subjects are delivered through the display control box. The trainees use the control panel to adjust the turret gun, adjust the height and horizontal position of the gun barrel, so that the laser sensor fixed on the gun barrel can be aimed at the target device on the target plate. The button attached to the control panel is pressed to control the laser to turn on. The laser successfully hits the high-precision reflector on the target device. At this time, the laser sensor signal will jump, and the display control box will judge the hit situation. The target plate and the transmission mechanism are connected with quick-release bolts to facilitate the switching of target type targets and envelope targets. A limited reflection type photoelectric sensor is used. The principle of diffuse reflection is used. The target detection point uses a high-precision reflector, which can effectively reflect the laser signal.

[0006] The firing device comprises a gun barrel fixing device which is sleeved on the surface of the gun barrel through a clamp and a laser sensor or a whiteboard pen which is fixed on the side of the gun barrel fixing device through a connecting piece.

[0007] As a further solution of the present invention: the locking range of the built-in clamp of the gun barrel fixing device is 30mm to 125mm.

[0008] As a further solution of the present invention: the base is fixed to the head of the armored vehicle by a magnet, and the side thread is connected with a locking nut that abuts against the surface of the armored vehicle. By adjusting the position of the base, it is adsorbed on the head of the armored vehicle, and then the locking nut abuts against the surface of the armored vehicle to lock and position it, and the inclination of the base can be adjusted so that the transmission mechanism installed at the upper end is horizontal, which is convenient for subsequent shooting detection.

[0009] As a further solution of the present invention: the transmission device comprises a shell and a lead screw driven by a brushless DC motor in the inner cavity of the shell, the surface of the lead screw is slidably connected to a sliding plate, the inner cavity of the shell is provided with a guide groove slidably connected to the sliding plate, the top of the sliding plate is slidably connected to a lifting plate, the top of the lifting plate is fixedly connected to a connecting end, the bottom of the target plate is fixedly connected to a plug-in plate plugged into the inner cavity of the connecting end, the surface of the plug-in plate is threadedly connected to a limiting bolt, the side of the connecting end is provided with a limiting groove slidably connected to the limiting bolt, and the shell The surface of the body is fixedly connected with a guide rail, the inner cavity of the guide rail is provided with a reducing guide rail, the surface of the lifting plate is fixed with a guide bearing abutting against the surface of the reducing guide rail, the motor is controlled to rotate by the motor control board to drive the lead screw to rotate, and the lifting plate is driven to rotate left and right by the sliding plate to realize the left and right movement control of the target plate, one side of the reducing guide rail is a plane, and the other side is a curved surface, and the horizontal movement of the target plate or the horizontal and vertical composite movement can be realized by installing the reducing guide rail in the forward and reverse directions, and then the target plate can be moved up and down in various ways by adjusting the position of the reducing guide rail.

[0010] As a further solution of the present invention: one side of the variable diameter guide rail is a plane, and the other side is a curved surface, and can be locked in the guide rail by bolts in both directions.

[0011] As a further solution of the present invention: the detection method includes the following three methods:

[0012] The first type: fast and accurate aiming and firing. When the indicator light of a certain target on the target board lights up red, the gun barrel needs to be adjusted in height and horizontal direction so that the laser sensor fixed on the gun barrel aims at the target device near the indicator light. Press the firing button. If the laser sensor signal of the display control box jumps, it means a hit. Then the current indicator light goes out and the system randomly lights up another indicator light. Then the trainee repeats the operations of adjusting the gun and firing.

[0013] The second type: steadily tracking the target. When the target indicator light on the target plate lights up red, it is necessary to adjust the height and horizontal position of the gun barrel so that the laser sensor fixed on the gun barrel aims at the target device near the indicator light. Long press the ranging button. If the indicator light goes out, it means that the target is successfully tracked for 2 seconds, and then release the ranging button. Next, the trainees repeat the operations of adjusting the gun and ranging. Smoothly tracking the target simulates the movement of the target. The system can control the reciprocating motion of the target plate. The variable diameter guide rail on the transmission device has a flat surface on one side and a curved surface on the other. By installing the variable diameter guide rail in positive and negative directions, the horizontal motion of the target plate or the horizontal and vertical composite motion can be achieved. The limit switch uses a travel switch. The two travel switches are installed near the two end points of the lead screw. When the lead screw drives the sliding plate to move and hits the travel switch, the motor changes the direction of rotation and drives the lead screw to drive the target plate to move in the direction of the other limit switch.

[0014] The third type: drawing an envelope target. The target board is flipped over to an envelope target, and the laser sensor is replaced with a whiteboard pen. The whiteboard pen is placed in a round tube with a spring installed inside the tube, so that the whiteboard pen has a certain amount of forward and backward extension. The height and horizontal position of the gun barrel are adjusted through the control panel so that the whiteboard pen can draw a pattern on the envelope target. The training staff compares the overlap between the drawn pattern and the envelope target and gives corresponding score judgments. The drawn pattern can be easily wiped off and continued to be drawn next time.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
