Hit recognition electronic target shooting system and recognition method thereof

Abstract

A hit recognition electronic target shooting system and a recognition method thereof are revealed. The system includes an electronic target and at least two practice guns. The electronic target is activated and at least two users hold the practice guns and pull triggers to shoot the electronic target simultaneously. After detecting a light beam from the light beam source of the practice gun that hit the electronic target first, a light sensor delays for a period of time to receive light signal. Simultaneously a sensing signal is transmitted to a control unit. Thus the control unit recognizes the practice gun that hit the electronic target first. Thereby many users respectively hold a practice gun to shoot the same electronic target simultaneously and which practice gun first hits the electronic target can be recognized. A better shooting practice, training competition or entertainment is achieved.

What is claimed is: 
     
         1 . A hit recognition electronic target shooting system comprising an electronic target and at least two practice guns; wherein the electric target includes a box, a diffusion plate disposed on a front surface of the box, a light sensor mounted in the box and corresponding to the diffusion plate, and a control unit connected to the light sensor and indicating lights;
 the control unit controls on/off state of the indicating lights that emits light with colors correspondingly according to the color of a light beam source of the practice gun that first hit the electronic target;   the practice gun includes a trigger connected to an activation unit and the light beam source connected to the activation unit; the light beam source of each of the practice guns has different light frequency, power, wavelength or periodic modulation/coding with a kind of carrier signal; the light beam source is activated by the activation unit while pulling the trigger and then the light beam source emits a pulsed light beam and the pulsed light beam is received by the light sensor.   
     
     
         2 . The system as claimed in  claim 1 , wherein the control unit is connected to an audio unit; the audio unit is a buzzer and is controlled by the control unit to play sounds or not. 
     
     
         3 . The system as claimed in  claim 1 , wherein the control unit is connected to a memory unit that is used for recording sensing state of the light sensor. 
     
     
         4 . A recognition method of a hit recognition electronic target shooting system having an electronic target and at least two practice guns comprising the steps of:
 turning on the electronic target first and a light sensor of the electronic target starting sensing light;   holding the practice gun and pulling a trigger of the practice gun at the same time to shoot the electronic target by at least two users respectively; activating a light beam source of the practice gun by the trigger of the practice gun through an activation unit so that the light beam source emits a light beam to the electronic target;   diffusing the light beam from the light beam source by a diffusion plate of the electronic target to be sensed by a light sensor after the first practice gun hitting the electronic target;   sensing the light beam from the light beam source, stopping receiving light signals for a period, and transmitting sensing signals to a control unit by the light sensor;   recognizing the light beam source of the first practice gun hit the electronic target by the control unit for control of indicating lights to emit light; and   emitting light with color corresponding to the practice gun hit the electronic target by the indicating light while each of the indicating lights emits light with different colors corresponding to respective practice gun.   
     
     
         5 . The method as claimed in  claim 4 , wherein the light beam source of the practice gun has different light frequency, different power, different wavelength, or different periodic modulation/coding with a kind of carrier signal. 
     
     
         6 . The method as claimed in  claim 4 , wherein after the step of recognizing the light beam source of the practice gun first hit the electronic target by the control unit, an audio unit is controlled by the control unit to play sounds. 
     
     
         7 . The method as claimed in  claim 4 , wherein after the step of recognizing the light beam source of the practice gun first hit the electronic target by the control unit, a memory unit records information sensed by the light sensor and related to the practice gun hitting the electronic target.
