The light curtain of the sector surface is composed of a plurality of laser beams in a dispersed emission state, the emission angle range of the sector surface laser can be 30-90 degrees, but the method is not limited to the range, and the emission angle range can be adjusted according to actual conditions. After the first light curtain 111 and the second light curtain 112 are arranged to be fan-shaped light curtains, the whole structure of the device can be simplified, the installation range and the area of functional components similar to the emitter and the receiver on the target frame can be reduced, the risk that the functional components similar to the emitter or the receiver are hit by bullets is reduced, the installation and debugging of the first emitter 101 and the second emitter 102 are more convenient, and the later maintenance and overhaul cost is reduced.

The receiving device comprises a first receiver 201 and a second receiver 202, wherein the first receiver 201 and the second receiver 202 are used for receiving the laser beams emitted by the first light curtain 111 and the second light curtain 112 respectively, so that the first light curtain 111 and the second light curtain 112 can be constructed in a layered mode in front of the target surface 400.

In this embodiment, as shown in fig. 3 and 4, the target surface 400 may be vertically disposed, and the direction perpendicular to the target surface 400 may be the direction in which the bullet 500 is shot toward the target surface 400, i.e., the direction indicated by the horizontal arrow.

It is understood that the target object 500 in this embodiment may be various bullets, such as metal bullets, rubber bullets, BB bullets, etc., in the solution of this embodiment, the positioning information of the target object 500 is obtained independently from the target surface 400, the target surface 400 only plays a role of alignment and aiming, and the target surface 400 may be replaced with different specifications or forms according to the target practice requirement.

The device of this embodiment has target frame 300, first transmitter 101, second transmitter 102, first receiver 201 and second receiver 202 fixed mounting in target frame 300, four frames that target frame 300 connects gradually, these four frames are upper ledge A, lower ledge C, left frame B and right frame D respectively, target surface 400 is located the region that upper ledge A, lower ledge C, left frame B and right frame D injectd, it can be understood that upper ledge A is located the upside region of target surface 400, lower ledge C is located the downside region of target surface 400, left frame B is located the left side region of target surface 400, right frame D is located the right side region of target surface 400.

The shape of the target 300 is not limited to this, and other frame structures having four or more frames may be used.

In this embodiment, the first mounting areas for mounting the first and second receivers 201 and 202 are provided at most on both sides of the circumference of the target surface 400, that is, the first and second receivers 201 and 202 are provided at most along both sides of the circumference of the target surface 400. For example, a first mounting area may be provided on opposite or adjacent sides of the periphery of the target surface 400, and a second mounting area may be provided on the opposite side of the target surface from the first mounting area; or the second mounting area is arranged at one side adjacent to the first mounting area; or the second mounting region is provided between the opposite side and the adjacent side of the first mounting region. It is understood that after the first mounting areas for disposing the receiving devices are disposed at most two sides around the target surface 400, the second mounting areas for disposing the emitting devices can be disposed at different positions around the target surface 400 according to different mounting requirements.

In one implementation, when the first receiver 201 and the second receiver 202 are respectively disposed on opposite borders of the target frame 300, the first emitter 101 and the second emitter 102 may also be respectively disposed on two opposite borders of the target frame 300, and the first receiver 201 and the second receiver 202 respectively receive the first light curtain 111 and the second light curtain 112 in opposite directions. In some embodiments, the opposing two borders may be upper and lower borders a and C, or left and right borders B and D, e.g., the first and second emitters 101 and 102 are mounted to the upper and lower borders C and a of the aperture 300 when the first and second receivers 201 and 202 are mounted to the upper and lower borders a and C, respectively, of the aperture 300; or first emitter 101 and second emitter 102 are mounted to right frame D and left frame B of aperture 300, respectively, when first receiver 201 and second receiver 202 are mounted to left frame B and right frame D of aperture 300, respectively.

Referring to fig. 1, in one embodiment, where first receiver 201 and second receiver 202 are positioned along upper frame a and lower frame C of aperture 300, respectively, first emitter 101 may be mounted to lower frame C of aperture 300 and second receiver 202 may be mounted to upper frame a of aperture 300. The first emitter 101 arranged in the upper frame a emits the first light curtain 111 towards the first receiver 201 arranged in the lower frame C; the second emitter 102 disposed in the lower frame C emits the second light sheet 112 toward the second receiver 202 disposed in the upper frame a. Thus configured, the projection overlap area 122 of the first light sheet 111 and the second light sheet 112 is defined by the left and right boundaries of the first light sheet 111 and the left and right boundaries of the second light sheet 112, and when the first emitter 101 and the second emitter 102 are respectively installed near the middle points of the upper frame a and the lower frame C, the projection overlap area 122 may have a diamond shape, and the projection overlap area 122 is located in the central area of the target frame 300, so that the target surface 400 can be located in the central area of the target frame 300.

Referring to fig. 2, in other embodiments, the first receiver 201 and the second receiver 202 may be disposed in two adjacent directions in front of the target surface 400, and the first receiver 201 and the second receiver 202 disposed adjacent to each other intersect perpendicularly and are substantially L-shaped. Thus, the first emitter 101 and the second emitter 102 may be disposed on two adjacent frames of the target frame 300, and the first receiver 201 and the second receiver 202 can receive the first light curtain 111 and the second light curtain 112 respectively in adjacent directions. It is understood that two adjacent frames may be a lower frame C and a right frame D, or a left frame B and a right frame D, or an upper frame a and a left frame B, or an upper frame a and a right frame D.

For example, where the first receiver 201 and the second receiver 202 are disposed adjacent to each other, the first receiver 201 and the second receiver 202 may be disposed along the lower frame C and the right frame D of the aperture 300, meanwhile, the first transmitter 101 may be mounted to the upper frame a, the second transmitter 102 may be mounted to the left frame B, after the arrangement, the first emitter 101 of the upper frame a emits the first light curtain 111 towards the first receiver 201 arranged on the lower frame C, the second emitter 102 arranged on the left frame B emits the second light curtain 112 towards the second receiver 202 arranged on the right frame D, the projection overlapping area 122 of the first light curtain 111 and the second light curtain 112 is defined by the left boundary of the first light curtain 111, the right boundary of the first light curtain 111, the upper boundary of the second light curtain 112, the lower boundary of the second light curtain 112 and the second receiver 102 arranged on the lower frame C of the target frame 300, and the projection overlapping area 122 is in an irregular pentagon shape.

In some embodiments, when the first receiver 201 and the second receiver 202 are disposed along two adjacent borders in front of the target surface 400, the first emitter 101 and the second emitter 102 may also be disposed between the adjacent and opposite borders, with the first receiver 201 and the second receiver 202 receiving the first light curtain 111 and the second light curtain 112, respectively, in a direction between the adjacent and opposite borders. For example, first receiver 201 and second receiver 202 may be positioned along lower frame C and right frame D of aperture 300, respectively, first emitter 101 may be mounted at the junction of upper frame A and right frame D, which is the upper right corner of aperture 300, and second emitter 102 may be mounted at the junction of upper frame A and left frame B, which is the upper left corner of aperture 300.

It is understood that, in other embodiments, after the first receiver 201 and the second receiver 202 are respectively disposed on the left frame B and the upper frame a, the installation form of the first transmitter 101 and the second transmitter 102 can refer to the description in the above embodiments, and the description thereof is omitted.

In this embodiment, when the first receiver 201 and the second receiver 202 are respectively installed on the opposite or adjacent frames of the target frame, the first emitter 101 and the second emitter 102 can be flexibly adjusted according to the actual installation requirement, and the installation positions of the first emitter 101 and the second emitter 102 are not limited in this embodiment.

It can be seen by combining the above embodiments that, in this embodiment, after the first receiver 201 and the second receiver 202 are respectively installed on the opposite or adjacent frames of the target frame 300, the receiving device only occupies the areas of at most two sides around the target surface 400, and compared with the related art in which the receiving device is installed in the areas of more than three sides around the target surface 400, the receiving device can effectively reduce the risk of being hit by a target object, and reduce the equipment loss and the maintenance cost.

In order to achieve automatic acquisition of the positioning information of the target object, the laser screen positioning automatic target scoring device of the embodiment further includes a control device and at least one mobile terminal device in communication connection with the control device. The control device can acquire the positioning information of the target object 500 sensed by the first receiver 201 and the second receiver 202, and calculate the information of the target practice result according to the positioning information to display or send the information to the mobile terminal device to display, so that a user can check the information of the target practice result in real time. For example, the control module may be a host computer, and the mobile terminal device may be a mobile phone, a tablet computer, or the like. The communication connection between the control device and the mobile terminal device may be a wireless network, such as bluetooth or wifi transmission, but is not limited thereto.

In the scene that has a plurality of target positions, the automatic target scoring device of every target position can adopt mobile terminal to control respectively, and mobile terminal can control the automatic target scoring device in the target range in any position of target range for the management of target range is more convenient, and the result of shooting information can be saved in personal storage device, smart mobile phone for example, makes the training of shooting more intelligent like this, has promoted user's experience.

The scheme provided by the embodiment realizes that the acquisition of the positioning information of the target object 500 does not depend on the target surface 400, and avoids the phenomenon of missing bullets and missing reports caused by repeated bullet holes of the target surface 400. The positioning information of the target object 500 is obtained through the first receiver 201 and the second receiver 202 arranged on one side of the target frame 300, so that the target practice can be fast, safe, efficient and accurate. The target-shooting missing report rate and precision error are small, the material consumption cost is low, the target-shooting missing report method is not limited by gun types and target object 500 types, and the target-shooting missing report method is more widely applied.

After the first receiver 201 and the second receiver 202 are disposed on the target frame 300 along adjacent or opposite borders, the first receiver 201 and the second receiver 202 may be disposed on the same plane parallel to the target surface 400, the first receiver 201 and the second receiver 202 need not be disposed side by side in the direction perpendicular to the target surface 400, and the first light curtain 111 and the second light curtain 112 are constructed in layers by adjusting the distance between the first emitter 101 and the second emitter 102 in the direction perpendicular to the target surface 400, so that the thickness of the target frame 300 can be reduced, and the product volume can be further reduced.

The first receiver 201 and the second receiver 202 of this embodiment are positioned adjacent or opposite on the aperture plate 300, this can be coordinated with the placement of the first and second emitters 101 and 102 at different locations on the aperture 300, and a first light curtain 111 and a second light curtain 112 for sensing the positioning information of the target object 500 are constructed in layers in front of the target surface 400, the projected overlapping area 122 covering the target surface 400 is formed by the first light sheet 111 and the second light sheet 112, so that the receiving device can realize the automatic positioning of the target object after being arranged at most two borders around the target frame 300, after the arrangement, when the target object deviates from the direction and accidentally hits the other two frames of the target frame 300, the damage of the functional components such as the receivers is avoided, the risk that the first receiver 201 and the second receiver 202 are hit by the target object 500 is reduced, the functional stability of the device is improved, and the service life of the device is prolonged.
