Problems solved by technology

[0003] The disadvantages of the above-mentioned intelligent target reporting and positioning system are as follows: (1) its four microphones form a T-shaped array and adopt an array mode away from the target, so that the impact point and the coordinate points of the four microphones form a three-dimensional space. On the one hand, the mathematical model is comparatively Complicated, and on the other hand, the placement of the four microphones is also troublesome
(2) Because it uses wired communication, it can only be used for static target reporting, and it is powerless for dynamic target reporting
In addition, when the target location is far away, wired communication is very inconvenient

Abstract

A shock wave target teller system comprises the top and bottom machines connected through wireless communications, with the bottom machine composed of T matrix shock wave sensing units, micro processor, wireless data transmission block, T matrix shock wave sensing unit made of 4 shock wave sensors Q1, Q2, Q3, and Q4 at the bottom and top of the target teller surface, entries of four shock wave sensors connecting with the entry of the micro processor, which in turn connects with the wireless data transmission block, with the top machine made of wireless data transmission block, computer, and display, wireless data transmission block connecting with the computer, and the output of the computer connecting with the display. It can realize dynamic target telling, no matter the shape of the target.

Description

technical field [0001] The invention relates to a shock wave target reporting system, which is a target impact point positioning system suitable for army live ammunition shooting training. Background technique [0002] A Chinese patent discloses a "intelligent target reporting and positioning system" (publication number: CN1462864A). It mainly includes a microphone array, a data collector, a communication cable, a target reporting display, and a computer. It is characterized in that the array of four microphones is separated from the target, and the microphone is an ultrasonic microphone higher than 20KHz, and the array of four microphones is made into a T-shaped array. The shape is placed flat 0.5 meters in front of the target, so that the connection lines of microphones A, B, and C are parallel to the horizontal line of the target. The data collector is inserted into the computer data interface, and the data collector and the microphone array are ...
