Abstract
The present invention discloses a target reporting system using a laser azimuth sensor, which comprises an interface circuit, a computer and a target position. The present invention is characterized in that the target reporting system also comprises laser devices in a horizontal direction and a vertical direction, photosensitive receivers in a horizontal direction and a vertical direction corresponding to the laser devices, and a controller; light beams generated by the laser devices in a horizontal direction and a vertical direction are mutually perpendicular so that a light beam square net is formed; photosignals received by the photosensitive receivers are converted to electric signals by the photosensitive receivers, and the electric signals are transmitted to the controller and the computer; after the electric signals are treated by the computer, shooting circular numbers and impact points are displayed. The present invention has the advantages of accurate measurement and automatic display of shooting circular numbers, high work efficiency and low target misreporting record. The present invention is suitable for various shooting ranges.
Description
The present invention relates to target indicating system, especially relate to a kind of hit telling system that uses laser azimuth sensor.
The hit telling system that is used to shoot indication at present has following several: first kind is that camera is placed in face of the target sheet, by transmission cable the point of impact above the target sheet is shown in then and is placed on shooter's display in front, this hit telling system shell hole on target sheet is obscured more easily, can't distinguish the number of rings of a nearest rifle, frequently change target sheet; Second kind is that target sheet is placed on the cable car, by the elevator motor target sheet is shifted near and sees, this hit telling system operating efficiency is too low, is unsuitable for continuous fire; The third is that target sheet is attached on the steel plate, a plurality of sound transducers are installed in the steel plate back, utilize point of impact to arrive the time difference of each sound transducer, calculate the orientation of point of impact, as publication number is that the patent of invention " ball firing automatic target checking, hit telling system " of CN1074753A promptly adopts this kind hit telling system, the shortcoming of its maximum is that bullet is mapped on the steel plate and can rebounds, and dangerous, cost is higher in addition; The 4th kind is the bullet in the survey mission of utilization infrared ray emitting-receiving system, shortcoming is that scorching hot bullet itself also can send infrared ray, infrared receiver can't distinguish that the infrared ray of receiving is the infrared ray that the infrared ray that sends of RF transmitter or bullet itself send, and indication of shots easily therefore just makes a mistake.
The object of the present invention is to provide a kind of hit telling system that can accurately measure and automatically show shooting number of rings, high efficiency, use laser azimuth sensor that wrong report target rate is low.
The object of the present invention is achieved like this: the present invention includes computer, interface circuit and target position, feature is also to comprise the horizontal direction laser instrument, the horizontal direction photoreceiver, the vertical direction laser instrument, vertical direction photoreceiver and controller, the light beam that horizontal direction laser instrument and vertical direction laser instrument send is orthogonal, horizontal direction photoreceiver and vertical direction photoreceiver all convert the optical signal that receives to the signal of telecommunication and are transferred to controller, being transferred to computer by controller again, after machine is handled as calculated is that the point of impact on number of rings and the target sheet shows on display with shooting result.
The present invention is the positioning principle according to mathematics midplane rectangular co-ordinate, respectively on the X-direction and install some on the Y direction to laser instrument and photoreceiver, all compile in order for every pair and go up corresponding item, the light beam that horizontal direction laser instrument and vertical direction laser instrument send constitutes the light beam grid.Laser instrument sends a very thin light beam and is mapped on the photoreceiver, photoreceiver will be exported a zero level, vertically pass the moment of light beam grid when bullet, the light beam of horizontal direction and vertical direction all is cut off, horizontal direction photoreceiver and vertical direction photoreceiver all can send a pulse signal to controller, controller is transferred to computer to signal then, after machine is handled as calculated be that point of impact on number of rings and the target sheet shows on display, the ejaculator is come into plain view shooting result.The monochromaticjty that the present invention makes full use of laser is good, good directionality, concentration of energy, be difficult for the advantage of diffusion, laser instrument and photoreceiver constitute man-to-man aspect sensor relation, can not go here and there mutually between the light beam, add the employing Computer Processing, so the present invention has and can accurately measure and automatically show shooting number of rings, high efficiency, the advantage that wrong report target rate is low, security is good.Extensively be suitable for various military affairs, the use of physical culture shooting range.
Fig. 1 is a system block diagram of the present invention.
Fig. 2 is the light beam grid schematic diagram that laser instrument and photoreceiver constitute.
Fig. 3 cuts off the schematic diagram of light beam for bullet.
Fig. 4 shows the schematic diagram of target sheet for display.
Fig. 5 is rectangular co-ordinate and polar schematic diagram.
Below in conjunction with embodiment and contrast accompanying drawing the present invention is described in further detail.
The present invention is by the horizontal direction laser instrument, the horizontal direction photoreceiver, the vertical direction laser instrument, the vertical direction photoreceiver, controller, interface circuit, computer and target position are formed, the light beam that horizontal direction laser instrument and vertical direction laser instrument send is orthogonal, constitute the light beam grid, horizontal direction photoreceiver and vertical direction photoreceiver all convert the optical signal that receives to the signal of telecommunication and are transferred to controller, being transferred to computer by controller again, after machine is handled as calculated is that the point of impact on number of rings and the target sheet shows on display with shooting result.
Can shelter from the light beam of horizontal direction and vertical direction awing in order to ensure bullet, distance should be less than the bullet diameter between the adjacent beams of horizontal direction and vertical direction.The wavelength of laser instrument is 650 nanometers, and the receive window peak value of response of photoreceiver also is 650 nanometers.
Place a target sheet on the target position that is parallel to light beam grid rear 3 centimeters, a crosspoint of center on the light beam grid is chosen as the origin of coordinates, horizontal direction is an X-axis, and vertical direction is a Y-axis, and the center of circle and the origin of coordinates with target sheet overlaps again.Computer can be changed to polar coordinates (ρ, θ) with the rectangular co-ordinate (X, Y) of point of impact, and wherein ρ represents the number of rings of hitting, and θ represents the azimuth of point of impact.
Its computing formula is:
θ＝arctg(Y/X)
