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 target surface 400 has a plurality of different side areas around it, and the first mounting area for mounting the first receptor 201 and the second receptor 202 is located on one of the plurality of different side areas, that is, the first receptor 201 and the second receptor 202 are arranged along at most one side of the target surface 400 around it.

The second mounting region may be mounted to the side opposite the first mounting region, or to an adjacent side of the first mounting region, and may also be mounted between the opposite side and the adjacent side of the first mounting region. It is understood that after the first installation region for installing the receiving device 200 is set at one of the plurality of different side regions, the second installation region for installing the launching device 100 can be respectively set at different side positions of the target surface 400 according to different installation requirements.

For example, the first receiver 201 and the second receiver 202 may be mounted side by side to one of the upper frame a, the lower frame C, the left frame B, and the right frame D of the aperture 300 in a direction perpendicular to the target surface 400. The first emitter 101 and the second emitter 102 are disposed on the target frame 300 at the opposite side frame to the receiving device 200, at the adjacent side frame, or between the opposite side frame and the adjacent side frame, and when disposed at the opposite side frame, the first receiver 201 and the second receiver 202 are used for receiving the first light curtain 111 and the second light curtain 112 in the opposite directions, respectively; when the first light curtain and the second light curtain are arranged on adjacent frames, the first receiver 201 and the second receiver 202 respectively receive the first light curtain 111 and the second light curtain 112 along adjacent directions; when the automatic target reporting device is arranged between the opposite frame and the adjacent frame, the first receiver 201 and the second receiver 202 respectively receive the first light curtain 111 and the second light curtain 112 along the opposite direction and the adjacent direction, after the arrangement, the receiving device 200 only occupies the area of one side around the target surface 400, compared with the situation that the receiving device 200 is arranged in the area of multiple sides around the target surface 400 in the related art, the risk that the receiving device 200 or the transmitting device 100 is hit and damaged can be effectively reduced, in addition, the transmitting device 100 can flexibly adjust the installation position relative to the receiving device 200, so that the automatic target reporting device can be flexibly assembled according to the characteristics of the actual installation scene, and can be suitable for different target hitting requirements.

With continued reference to fig. 1, in some embodiments, the first and second receivers 201, 202 may be positioned along the lower frame C of the aperture 300, and the first and second emitters 101, 102 may be mounted to the upper frame a of the aperture 300, with the first and second emitters 101, 102 of the upper frame a emitting the first and second light sheets 111, 112 respectively toward the first and second receivers 201, 202 positioned at the lower frame C. The projected overlap area 122 of the first light sheet 111 and the second light sheet 112 is defined by the right side boundary of the first light sheet 111, the left side boundary of the second light sheet 112, and the lower frame C of the aperture 300. The first emitter 101 and the second emitter 102 may be disposed at an interval on the upper frame a of the target frame 300 and near the midpoint of the upper frame a, and the area of the projection overlapping area 122 formed at this time is relatively large, for example, the projection overlapping area 122 is triangular, two adjacent sides of the triangle respectively overlap the boundaries of the first light curtain 111 and the second light curtain 112, and the bottom side overlaps the lower frame C, because the bottom side is a specific length and the height of the triangle tends to be maximum, the projection overlapping area 122 has a relatively large area, so that the coverage areas of the first light curtain 111 and the second light curtain 112 can be fully utilized, so that the target surface 400 can be adapted to the smaller target frame 300, and the product volume can be further reduced.

With continued reference to FIG. 2, in still other embodiments, the first receiver 201 and the second receiver 202 may be disposed along the lower frame C of the aperture 300, the first emitter 101 may be disposed at the intersection of the upper frame A and the left frame B, and the second emitter 102 may be disposed at the intersection of the upper frame A and the right frame D, i.e., the first emitter 101 may be disposed at the upper left corner of the aperture 300, the second emitter 102 may be disposed at the upper right corner of the aperture 300, and the first emitter 101 at the upper left corner of the aperture 300 and the second emitter 102 at the upper right corner of the aperture 300 may emit the first light curtain 111 and the second light curtain 112 toward the first receiver 201 and the second receiver 202 disposed at the lower frame C, respectively. The projection overlapping area 122 of the first light curtain 111 and the second light curtain 112 is an isosceles triangle. At this time, the distance between the first emitter 101 and the second emitter 102 and the projection overlapping area 122 is larger, so that the possibility that the first emitter 101 and the second emitter 102 are hit by the target object 500 can be reduced, and the service life of the device can be prolonged.

It is understood that, when the first receiver 201 and the second receiver 202 are disposed in the lower frame C, the first transmitter 101 and the second transmitter 102 are not limited to the above arrangement, and in other embodiments, the first transmitter 101 may be disposed in the left frame B and the second transmitter 102 may be disposed in the right frame D; alternatively, the first emitter 101 is disposed in the left frame B, and the second emitter 102 is disposed in the upper frame a; alternatively, the first emitter 101 is disposed in the upper frame a, and the second emitter 102 is disposed in the right frame D; or the first emitter 101 is arranged at the upper left corner and the second emitter 102 is arranged at the right frame D; alternatively, the first emitter 101 is disposed in the left frame B and the second emitter 102 is disposed in the upper right corner.

In other embodiments, after the first receiver 201 and the second receiver 202 are disposed in one of the left frame B, the right frame D, or 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 here.

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.

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.

It can be seen from the above embodiments that, after the first receiver 201 and the second receiver 202 are arranged side by side in the direction perpendicular to the target surface 400 behind one of the borders of the target frame 300, they can be matched with the first emitter 101 and the second emitter 102 arranged at different positions on the target frame 300, and further, the first light curtain 111 and the 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, and the projection overlapping area 122 covering the target surface 400 is formed by the first light curtain 111 and the second light curtain 112, so that the receiving device 200 can realize automatic positioning of the target object after being arranged behind one of the borders of the target frame 300, and thus after being arranged, when the target object accidentally hits the other three borders of the target frame in a deviated direction, it will not cause damage to the functional components such as the receivers, and the risk that the first receiver 201 and the second receiver 202 are hit by the target object 500 is reduced, the service life of the equipment is prolonged.
