Operation principle:
Work as bullet during ball firing and pass supersonic image big screen, in its acoustic cavity, produce ultrasonic signal, the signal that ultrasonic signal processor part receives each sonac at first amplifies, the bandwidth of amplifier should be greater than 100KHZ, gain should be greater than 40dB. after signal reaches certain amplitude, deliver to bandpass filter, with some interference noises of filtering, to guarantee the signal to noise ratio of useful signal.And then deliver to main amplifier, under the situation of having got rid of interference noise, the gain of main amplifier should increase as much as possible, can reduce the error of the time difference like this.Main amplifier is delivered to level comparator after signal is amplified to enough amplitudes, delivers to the region decision circuit then, and the principle of region decision is that to receive early in one group of sensor that of signal is decided to be this zone effective, and it is invalid that remaining sensor should be considered as.Effectively regional in region decision, the time difference signal that single-chip microcomputer will be organized sensor takes out.Collect simultaneously the temperature value in the operatic tunes in real time, deliver to the positioning calculation industrial computer after treatment and resolve, to obtain x, the y variable in this coordinate.Then this x, y value being converted to the screen upper left corner is that initial point, level are to the right X-axis, are new coordinate figure in the image coordinate of Y-axis vertically downward, be converted into coordinate then with pixel, deliver to image control and play computer and carry out the identification and the comparison of image, to determine whether to hit the target that sets, carry out the evaluation of achievement.
In image control and the broadcast computer image document of having deposited some kinds is arranged, be fit to and various scenes and situation, the trainer can be therefrom selected arbitrarily to play it.The form of depositing of image is AVI, and image section is delivered to projector by the VGA mouth output of computer, and projector projects on the ultrasonic large-size screen monitors again.Audio signal is delivered to power amplifier by the sound card output of computer simultaneously, then by two stereo speaker outputs, to reproduce the scene in wartime.
During simulated training, shooter's laser gun is with laser point directive screen, and the CCD camera in time captures x, the y coordinate figure of the image at this luminous point place.This x, y value are sent into image control and play computer, and image control and broadcast computer compare judgement with x, y coordinate figure that is received and the target area that sets, and are the achievements that judges whether to hit or judge the ejaculator.
Master control partly includes the power supply control of each several part, and the statistics of trainer's achievement and printing can be connected, make things convenient for management and the use of user to data with the office automation system.
The characteristics of ultrasonic gunnery training system are the location of adopting the method realization live shell of localization by ultrasonic, make that this system environments adaptability is strong, positioning accuracy is accurate, reliability is high, the location is real-time, target surface utilization rate height.This system both can carry out simulated training also can carry out ball firing, both can carry out the shooting that precision shooting also can be carried out moving target and activity scene moving target.
