The MCU (Microcontroller Unit) 30 serves to control the overall operation of each component.

The field programmable gate array (FPGA) 60 is a semiconductor device including a programmable logic element and a programmable internal line. The field programmable gate array (FPGA) 60 drives the transmission drivers T1... TN under the control of the MCU 30 and receives the reception drivers ( The photoelectric conversion signal is received from R1... RN) and the through point of the target plate of the laser target 100 is calculated as a coordinate value. In the present embodiment, the FPGA 60 is used, but a high performance signal processor IC may be used instead of the FPGA 60.

The high-performance signal processor IC or field programmable gate array (FPGA) 60 may internally oscillate, but by using a more precise clock generator 40, a clock signal having a constant frequency to the high-performance signal processor IC or FPGA 60. To supply.

The standard time generation unit 50 provides a time point at which the shot bullet at the target plate of the laser target 100 arrives, that is, a penetration time.

The high performance signal processor IC or field programmable gate array (FPGA) 60 stores the calculated coordinate values and the penetrating time generated by the standard time generator 50 in an internal memory (not shown) or transmits them to the MCU 30. .

The laser target 100 is composed of a plurality of light emitting devices and a plurality of light receiving devices corresponding thereto, and a mesh type grid type target plate is formed between the light emitting devices and the light receiving devices by an optical signal. Here, the light emitting device is configured using a visible, invisible laser or light emitting diode (LED). The detailed structure of the laser target 100 is shown in FIG.

2 is a detailed block diagram illustrating the laser target 100 of FIG. 1. As shown in FIG. 2, the laser target 100 includes a plurality of light-emitting and light-receiving elements 120 and 130 arranged in a plurality of columns and rows on a target plate housing 110 having a predetermined shape. Here, the target plate housing 110 is vertically placed on the ground in a rectangular frame, for this purpose is not shown support is disposed. As shown in FIG. 2, the shape of the housing 110 may be penetrated back and forth so that the shooting position may be performed not only from the front but also from the back. Of course, the shape of the housing 110 may be other than the shape or animal shape of the head and the body of the human body. On one surface of the target plate housing 110, the light emitting devices 120 are disposed at a predetermined interval, that is, approximately 10 mm apart, and on the opposite surface, the light receiving devices 130 are disposed at a one-to-one correspondence to the optical signal in a grid shape. To form a target plate. In this case, in order to increase the density of the optical target plate formed, the plurality of light emitting devices 120 and the light receiving devices 130 installed in the housing 110 are enlarged in FIG. The size can be discerned and arranged in a matrix by combing at intervals of approximately 4 to 5 equal parts. Operation of the target device of the present invention having such a configuration will be described in more detail with reference to FIGS. 3 and 4.

When an operation signal is input through direct operation of the switch 10 or communication with the communication unit 20, the MCU 30 sends an operation command to the FPGA 60. When the FPGA 60 receives an operation command from the MCU 30, the FPGA 60 directly drives the transmission drivers T1... TN or a clock signal having a constant frequency generated by the clock generator 40. Outputs to drive the connected transmission drivers T1... TN. The transmission drivers T1... TN “on” the light emitting elements 120 correspondingly connected according to the driving signal applied from the high performance signal processor IC or the FPGA 60 to emit an optical signal. The light emitted from the light emitting device 120 is received by the light receiving device 130 installed on the opposite surface of the target plate housing 110 and is shown in FIG. 3 between the light emitting device 120 and the light receiving device 130. As described above, the lattice-shaped laser target 100 is made.

The light-receiving part of the device is momentarily turned on (on) off (on). That is, in the light emitting device 120 as shown in FIG. 4A, the optical signal is continuously emitted in the form of "ON" or pulse, and the light receiving device 130 receives the light signal to receive the reception driver R1. Through photoelectric conversion through the high performance signal processor IC or FPGA (60). At this time, when the bullet 140 shot by the shooter passes the laser target 100, the light receiving element 130 in the region where the bullet 140 of the laser target 100 passes does not receive the emitted light, but at this point. One pulse is generated as shown in (b) of 4, and the high performance signal processor IC or FPGA 60 recognizes this signal as a signal passing through the horizontal axis. The bullet passing through the horizontal axis passes through the portion of the laser target 100 configured as the vertical axis. Similarly, when passing through the target, the light receiving part of the area passing through the area between the vertical axes 1? OFF) → ON ”. That is, one pulse is generated, and this signal is recognized as a signal passing through the vertical axis. High-performance signal processor IC or FPGA 60 is stored in advance the coordinate information centered on the reference point on the target plate of the light emitting elements 120 and the light receiving elements 130 disposed in the target plate housing 110, the laser target Coordinate information is checked from the horizontal pulse signal and the vertical pulse signal of 100, or a program for calculating the coordinate information is stored to calculate the coordinate information based on the recognized signal. At this time, the high performance signal processor IC or FPGA 60 receives the time information from the standard time generation unit 50 and stores the time when the bullet passes through the laser target 100, that is, the time coordinate with the pass coordinate value. As the passing time of the laser target 100 is also stored, the shooter performs a predetermined number of shots so that when a predetermined number of hit points occur, it is possible to know which target was hit at which shot. The FPGA 60 transmits coordinate information and time information about the impact point to the MCU 30 when the MCU 30 requests it. When the MCU 30 receives a data value request from the outside through the communication unit 20, the MCU 30 transmits the data received from the FPGA 60 to the outside. When sending the coordinate value, the value that recorded the time of passing point is also transmitted.

The shooter or the manager can communicate with the target device of the present invention at any time to see which target was hit at which time with the shooting time. As such, even if you do not go to the target plate and check it with your own eyes, you can know the location and time of the hit on the target plate at any time, so that you can easily manage all of the history such as literacy assessment related to shooting.
