Description

A kind of accurately laser target practice

Technical field

It the utility model is related to laser technology field, more particularly to a kind of accurately laser target practice.

Background technology

Target apparatus refers to be shot at the target of setting by certain rule, trains effect with burst fire, improves shooting The instrument of technology.Laser target practice is that a kind of light beam for sending generating laser is beaten on laser target a long way off, is shot at The device of training.

It currently there are the training equipment of the automatic target-indicating of two kinds of main flows.One of which is to use PSD photoelectric displacements Sensor, although this design can effectively reduce consumption of the throw-off practice training for national resources, PSD sensor sheets Body is expensive, manufacturing cost is high, and at present market sale the big many areas very little of PSD sensors, can only small range place Reason and calculating, can not be tested on a large scale.

Another kind design is to detect target surface by using ccd video camera, and the image photographed is handled by PC ends and calculated Go out laser and beat particular location in target surface, although this method cost is slightly lower with respect to PSD sensors, deposited in measurement accuracy Very big the problem of, good judgement can not be carried out by passing through the special circumstances such as target surface same position for bullet.

Current gunnery training, mostly using throw-off practice as major way, not only cost is larger, and with certain Danger.This training, the mode of indication of shots are all to have to obtain number of rings, the degree of accuracy and fairness by experience and observation by marker It is not high, and efficiency is low.

Utility model content

A kind of the defects of in order to overcome in the prior art, there is provided accurately laser target practice.

The utility model is realized by following proposal：

A kind of accurately laser target practice, the laser target practice include semiconductor laser gun, the semiconductor laser gun hair The laser beam penetrated is beaten on optical target, optical target electrical connection corresponding with adc data acquisition module, the adc data collection Module electrical connection corresponding with single chip processing module, the single chip processing module are corresponding with LCD display module and alarm module Electrical connection.

The optical target is made up of photo resistance, the photo resistance be ultraviolet photoresistor, infrared photoresistor, One kind in visible light photoresitor.

The single chip processing module be CPU, RAM, ROM, Timer/Counter, LPT, full duplex serial ports row mouth, One or several kinds in ADC/DAC, SPI, I2C, ISP, IAP.

The LCD display module be CCFL displays, light-emitting diode display, TN types liquid crystal display, STN types liquid crystal display, One kind in TFT type liquid crystal displays, number of rings is exported in the LCD display module.

The alarm module includes buzzer.

The beneficial effects of the utility model are：The utility model uses laser as shooting light source, using photo resistance group Into optical target, the target apparatus so combined is not only less demanding to training court, and trains cost low, safe and efficient, can be complete Trained into high accuracy shooting.

Embodiment

The utility model is further illustrated with reference to Fig. 1, Fig. 2 and specific embodiment：

A kind of accurately laser target practice, the laser target practice include semiconductor laser gun, the semiconductor laser gun hair The laser beam penetrated is beaten on optical target, optical target electrical connection corresponding with adc data acquisition module, the adc data collection Module electrical connection corresponding with single chip processing module, the single chip processing module are corresponding with LCD display module and alarm module Electrical connection, the single chip processing module are CPU, RAM, ROM, Timer/Counter, LPT, full duplex serial ports row mouth, ADC/ One or several kinds in DAC, SPI, I2C, ISP, IAP, the LCD display module are CCFL displays, light-emitting diode display, TN types One kind in liquid crystal display, STN types liquid crystal display, TFT type liquid crystal displays, the output ring in the LCD display module Number.Semiconductor laser gun is used to utilize the photo resistance detecting location in optical target, laser as ejecting gun in the utility model The laser beam of source transmitting, gets on the target surface being made up of photo resistance, and the change of illumination makes the voltage of photo resistance change, So as to which the detection to target surface voltage signal is exactly the detection to laser beam, reaches and complete the external purpose of detection of practicing shooting, and voltage The output quantity of signal passes through adc data acquisition module, and then digital quantity is into single chip processing module after output processing, by place Reason and then the display output number of rings in LCD display module.

The optical target is made up of photo resistance, the photo resistance be ultraviolet photoresistor, infrared photoresistor, One kind in visible light photoresitor.Because photo resistance reduces with intensity of illumination increase resistance, therefore in the utility model When practicing shooting every time, i.e. semiconductor laser gun transmitting beam of laser is beaten on the target surface of optical target, the photo resistance resistance on optical target It is worth respective change, according to the difference of light position, the photo resistance of diverse location has difference, so as in photo resistance Voltage change；Photo resistance in optical target is distributed as X, Y-axis and four quadrants, builds mathematical modeling using photo resistance, often One ring determines its position by 4 photo resistance, and all photo resistance are connected to high level each via a divider resistance, another Individual pin ground connection, while partial pressure amount is linked into by wire order in a fixed order and is connected to adc data processing module Input on, therefore when laser is irradiated on photoelectricity target surface, the resistance of photo resistance has certain change, so as to cause The change of photoelectricity target voltage, the changing value of all photo resistance is gathered by adc data processing module, compares and draws changing value most Four big points, the position that laser beaten on target surface is determined by the programme-control in single chip processing module, so that it is determined that ring Number, recently enters in LCD display module and is shown.

The alarm module includes buzzer.Middle in the utility model to be warned using buzzer, cost is relatively low, still Because the output current of single-chip microcomputer is smaller, so current driving circuit must be used, it is contemplated that the extension effect of alarm module, institute So that ULN2003 electric currents driving chip can be used to drive buzzer.

Semiconductor laser gun, optical target, the detailed internal configuration of adc data acquisition module and work are former in the utility model Manage as known technology, will not be repeated here.

As shown in Fig. 2 according to hardware logic, each processing module is called in principal function order, is mutually relied on and mutually dry Disturb, the program of each processing module write using sub-module programming, be first ADC collection and processing letter Number, includes ADC initialization and driving, handles function followed by one-chip computer module, includes the judgement for reading in data Compare and handle, also the processing function of LCD display module and alarm module, include LCD initialization, LCD read/write functions And the drive module of buzzer.

Although more detailed elaboration is done to the technical solution of the utility model and has been enumerated, it will be appreciated that for For those skilled in the art, modification is made to above-described embodiment or uses equivalent alternative solution, this skill to this area Be for art personnel it is clear that on the basis of without departing from the utility model spirit these modifications or improvements, belong to In the scope of the requires of the utility model protection.
