Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention done concrete introduction.
With reference to accompanying drawing 1, triangle ultrasonic automatic scoring round target system of structuring the formation includes three triangles and structures the formation sonac and temperature sensor, cavity target plate, sensor installation assembly, signals collecting resolve center, display computer；Being provided with three triangles at hohlraum target intralaminar part to structure the formation sonac and a temperature sensor, sensor resolves center by signal cable output to signals collecting, and signals collecting resolves and is connected with display computer centrally through data cable.Specifically, triangle ultrasonic automatic scoring round target system of structuring the formation includes structure the formation sonac and temperature sensor, cavity target plate, sensor installation assembly, signals collecting of three triangles and resolves center, display computer；Being provided with three triangles at hohlraum target intralaminar part to structure the formation sonac and a temperature sensor, sensor resolves center by signal cable output to signals collecting, and signals collecting resolves and is connected with display computer centrally through data cable.With reference to accompanying drawing 3, triangle ultrasonic automatic scoring round target system electric part of structuring the formation adopts main filter circuit, signal amplifier, threshold compataror, time difference enumerator, calculating coordinate device, serial port modular design to form.Signal amplifier adopts TL074 class high speed operation amplifier, and serial port adopts MAX232 agreement.
Cavity target plate adopts foamed plastic to make shaping, target sheet or target are pasted on outside foamed plastic, and hohlraum target intralaminar part is provided with triangle and structures the formation sonac installation assembly, and sensor installation assembly is arranged three sonacs, as preferably, the central point of three sonacs is in obtuse angle.So make the range difference between bullet and three sensors sufficiently large so that finally can be enough accurate during employing mathematical principle calculating bullet position.It is preferred that, the central point of three sonacs becomes hexagonal angle, and temperature sensor is also installed on sensor installation assembly, and sonac adopts rubber sound insulation packing ring to be installed on sensor installation assembly.
Signals collecting resolves center and includes main filter circuit, signal amplifier, threshold compataror, time difference enumerator, calculating coordinate device, serial port.Main filter circuit and sonac are directly connected to, after sonac receives ultrasonic signal, reach signal amplifier, filtered small-signal is amplified specific amplitude by signal amplifier, reach threshold compataror, threshold compataror is connected with time difference enumerator, and time difference enumerator is made up of CPLD logic counting circuit and High Precision Crystal Oscillator.Calculating coordinate device adopts microprocessor Design, time difference data collection is delivered to calculating coordinate device by time difference enumerator, bullet X, Y coordinate are carried out real-time resolving through special algorithm by time difference data and temperature data by calculating coordinate device, are sent to industrial computer (display computer) again through serial port.Bullet coordinate is shown over the display by display computer, and is added up by all shooting grades, conveniently viewing and inquiry.
With reference to accompanying drawing 2, Computing Principle is as follows:
The ultrasound wave produced when the present invention is by bullet flight in atmosphere carries out automatic target-indicating, and the key point of the present invention places three sonacs in the lower section that bullet flies by 120 °, as it is shown on figure 3, B1、B2、B3For sonac, its spacing is L, with B2The horizontal direction of central point is x-axis, with B2The vertical direction of central point is y-axis, if bullet coordinate points is P point, its coordinate be (x, y), B1Coordinate points be (a, b), B2Coordinate points be (0,0), produced by bullet ultrasound wave arrive B1Time be T1, arrive B2Time be T2, arrive B3Time be T3, B1With B2Time difference be Δ T1=T1-T2, B2With B3Time difference be Δ T2=T2-T3, PB1Distance be l1=T1× V, PB2Distance be l2=T2× V, PB3Distance be l3=T3×V.If α is angle PB2B1Concrete angle, if β is angle PB2B3Concrete angle,
Then
Alpha+beta=120 °；
The value of x, y can be solved.Above-mentioned formula have employed general mathematical principle, and the value calculating x, y is very convenient, and adopts triangle relation to be calculated, and not adopts hyperbola to carry out the resolving of pop-off.Therefore during bullet hits sensor center position between two, still can accurately indication of shots.
Native system is in order to improve indication of shots precision, and system adopts foamed plastic to make cavity target plate, and cavity target plate, except providing the target that can shoot, also can completely cut off the interference sound wave of outside, allow sonac only receive effective sound wave of hohlraum target intralaminar part.And foamed plastic is after bullet penetrates, shell hole is effectively closed, is greatly promoted service life.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry, above-described embodiment does not limit the present invention in any form, and all employings are equal to the technical scheme that the mode of replacement or equivalent transformation obtains, and all fall within protection scope of the present invention.
