Digitizing collection device and detection method based on antiaircraft gun operation parameter of weather modification

Abstract

The invention discloses a digitizing collection device and a detection method based on antiaircraft gun operation parameter of weather modification and relates to the technical field of weather modification gun operation detecting and sensing and automatic control, a position detecting circuit of the device is composed of a coaxial duplex complementary multi-turn potentiometer and a corresponding signal conditioning circuit, wherein the coaxial duplex potentiometer is composed of two independent potentiometers, a quantity detection circuit is composed of an approach switch, a 4N 25 optical coupler and a central processing unit, wherein the central processing unit is connected with all the circuits through a data bus / address bus / control bus, the coaxial duplex potentiometer is arranged at a rotation position of the azimuth angle controller of an antiaircraft gun of weather modification in the way of the coaxial duplex complementary multi-turn potentiometer, the approach switch is arranged at the ejection port of the antiaircraft gun so as to complete the automatic detection on the position and the angle of pitch of the antiaircraft gun operation; therefore, based on the TCP / IP (Transmission Control Protocol / Internet Protocol) data transmission, the time and number of shell launching can be detected automatically.

Description

technical field [0001] The invention relates to the technical field of monitoring, sensing and automatic control of weather-modifying artillery shooting operations, in particular to a digital acquisition device and a detection method based on operating parameters of a silhouette antiaircraft artillery. Background technique [0002] According to people's wishes, through artificial intervention, some local weather phenomena are transformed in the direction that is beneficial to people's intended purpose, so as to overcome or alleviate the disasters caused by severe weather. This scientific and technological measure to transform nature is called artificial weather modification, or human shadow for short. . [0003] With the development of society and the advancement of science and technology, the scientific effectiveness of anti-aircraft rain and hail in artificial weather modification (hereinafter referred to as shadow operation) has attracted more and more attention. As a da...

AI Technical Summary

Problems solved by technology

[0005] 1. The azimuth measurement problem: the electronic compass measurement is the azimuth sensor CANG10, and the geomagnetic field is used to realize the orientation function. The high-precision azimuth measurement can be obtained in the laboratory. Since the antiaircraft gun belongs to metal, it has a great influence on the electromagnetic field around the measurement. Large, the measurement accuracy of the electronic compass after it is installed on the anti-aircraft gun is greatly reduced, sometimes the error reaches tens of degrees, and its accuracy is far from meeting the measurement requirements, and the sensor is expensive, such as CANG10 sensor 4800 yuan / piece;

[0006] 2. The detection of the number of shells: the number of shells is obtained through voice recognition. The shelling sound recognition module uses HBR110 or RSC-300 voice recognition chips. The recognition rate in the laboratory is not high or high, and it is greatly affected by the environment. large, the method is not applicable to the product;

[0007] 3. Pitch angle measurement problem: use the inclination sensor SANG1000 to measure, the sensor is expensive, for example, the SANG1000 sensor is 4800 yuan / piece

[0008] Since there is no digital acquisition device for the operating parameters of the shadow antiaircraft gun, the method of "meteorological artillery fire detection system design" has the disadvantages of high cost and low precision, and it is far from meeting the design requirements of the digital acquisition device for the operation parameters of the shadow antiaircraft gun.
