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. .

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 daily work of business work, quick and convenient operation information collection can greatly improve work efficiency, allow management departments to obtain real-time information on the front line of operations in a timely manner, provide basic data for operation command and operation benefit evaluation, and solve the problem of command, operation, and evaluation over the years. Disjointed technical challenges.

At present, the start and end time, the number of shells fired, the azimuth and elevation angles of the human shadow antiaircraft artillery operation are obtained manually and the relevant information is reported to the human shadow command department and management department by telephone or radio. Therefore, there are difficulties in collecting operational data, The real-time monitoring of equipment operation status and other actual conditions consumes a lot of manpower and material resources. Due to too many intermediate links, manual errors and inaccuracies often occur. It is urgent to establish a detection system based on modern artillery operations. In 2008, the inventor proposed a system with Cygnal C8051F340 single-chip microcomputer, HBR110 voice recognition chip as the core, SANG1000 inclination sensor, CANG10 electronic compass and other peripheral circuits to solve the problems of low intelligence and poor security of the current artillery operation system in 2008. Gunnery Operation Inspection System and published a related article "Design of Meteorological Gunnery Inspection System" (Authors: Li Dong, Guo Weibo, Fan Changyuan, Huang Hua). However, there are many key technical deficiencies in the "meteorological shot detection system design":

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;

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;

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.

Since there is no digital acquisition device for operating parameters of shadow antiaircraft guns at present, and the method of "meteorological artillery fire detection system design" has the disadvantages of high cost and low precision, it is far from meeting the design requirements of digital acquisition device for operating parameters of shadow antiaircraft guns. The inventor has put forward a digital collection device and detection method based on the operating parameters of the figure antiaircraft gun by concentrating on the automatic acquisition technology of information such as the starting and ending time of the artillery shooting operation, the number of shells fired, and the azimuth and elevation angles, in order to hope that by introducing this device and method, Real-time monitoring of the start and end time of the operation, the number of shells fired, and the azimuth and elevation angle provide scientific data for operation management, which can not only achieve the purpose of scientific and standardized management, but also provide a strong guarantee for safe production.

The central microprocessor U1 is connected to the above-mentioned circuits through a data bus/address bus/control bus. The central microprocessor U1 of the acquisition device uses the LPC2387 chip to control the information acquisition, signal processing, communication and other processing operations of the entire system.

The measurement circuit is designed in a 4-wire system, and a precise constant current source is required in the 4-wire circuit. In addition, because the output signal of the unit measurement circuit Weaker, the signal needs to be amplified, and then A/D conversion is performed after amplification.

According to the characteristics of the ideal op amp, V ₊ = V _- =2.5V and there is no current flowing out of the V _- terminal, then the current flowing through R1 is 0.5mA. If there is no current in R3 and R4, the current in potentiometer RPD1 is equal to 0.5mA in R1, that is, the current flowing through potentiometer RPD1 is a constant current source of 0.5mA, and the differential amplifier circuit is TLC2652. R0 and R1 use high-precision resistors with the same temperature drift. When the switches K1 and K2 are in the other position, the current flowing through R0 is also a constant 0.5mA, which will be used for temperature compensation and calibration.

Figure 4 and Figure 5 provide a detection method based on the digital acquisition device of the operating parameters of the silhouette antiaircraft artillery, especially the installation. Figure 4 shows the mounting position of the described device on the Silhouette, which has 2 6mm holes, which are just right for the device to be installed. In addition, the pitch sensor is designed into the device and does not need to be installed separately. FIG. 5 shows that the coaxial double potentiometer RPD1 is installed in the rotation position U8 of the azimuth angle controller of the shadow antiaircraft gun in the form of a coaxial complementary multi-turn potentiometer. The IDB40NA proximity switch J1 is installed at the ejection port U9 of the antiaircraft gun, and when each shell case is withdrawn through the IDB40NA proximity switch J1, the IDB40NA proximity switch J1 outputs a high and low level change, thereby detecting the number of shells.

The present invention also provides a detection method based on the digital acquisition device of the silhouette antiaircraft gun operating parameters, especially a method for measuring the azimuth angle of the dual coaxial complementary multi-turn potentiometer based on the silhouette antiaircraft gun, comprising the following steps:

(1) The azimuth angle measurement method based on the double coaxial complementary multi-turn potentiometer is used to measure the resistance of each potentiometer of the double potentiometer in the device. Since the double is complementary, the omnidirectional angle measurement of the antiaircraft gun can be realized ;

(2) Add a suitable power supply to both ends of the double potentiometer, the voltage of the center tap of the potentiometer changes with the rotation of the potentiometer, and realizes the conversion from voltage measurement to angle measurement;

(3) Measuring the voltage of the center tap can measure the resistance of the potentiometer, so as to obtain the measurement data of any angle of azimuth, that is, the measurement data of the mechanical rotation angle of the silhouette antiaircraft gun;

(4) Under the instruction of the central microprocessor LPC2387, store the azimuth measurement data into the memory. The azimuth detection design adopts "the azimuth measurement method based on double coaxial complementary multi-turn potentiometers".

The azimuth measurement of the gun shooting operation is the key technology of the collector. The azimuth angle of the antiaircraft gun can be accurately measured by adopting the "azimuth measurement method based on double coaxial complementary multi-turn potentiometers". Due to the mechanical rotation of the potentiometer, its resistance is different , By measuring the resistance, you can measure the rotation angle of the device. In fact, the mechanical rotation angle of the multi-turn potentiometer is 360°, while the electrical angle cannot reach 360°, usually only about 340°, and the price of the particularly advanced ones is also very expensive. It can reach about 350°, so there is a measurement blind area. Therefore, the "azimuth measurement method based on double coaxial complementary multi-turn potentiometers" is proposed. By measuring the resistance of each potentiometer of the double potentiometer, due to the double It is complementary to realize the azimuth measurement of the antiaircraft gun; the measurement of resistance is usually to add a suitable power supply to both ends of the potentiometer, the voltage of the center tap of the potentiometer changes with the rotation of the potentiometer, and can be measured by measuring the voltage of the center tap The resistance of the potentiometer is measured to obtain the mechanical rotation angle, which solves the dead zone of the potentiometer during the rotation process.

Algorithm design principle: A potentiometer has a blind area during rotation. For example, if the measurement range of an electrical appliance is 0° to 330°, there is a 30° blind area. In this blind area, the measured values are all 0, which cannot meet the requirements of system design. . Therefore, the system uses dual potentiometers to complete the measurement of any angle.

The potentiometers are installed in the form of coaxial complementarity. After they are powered on, they will divide the voltage at the same time, and the two AD chips will also sample the divided voltage. When should the first potential be used? device as a benchmark? When should I use the second potentiometer as a reference? How to avoid the problem that the blind zone voltage cannot be measured? How do these two potentiometers work together to measure the angle? Here it involves a threshold setting problem. Set the threshold as U _L ~ U _H (if the potentiometer voltage is 3.3 volts, it can be selected as 0.9 ~ 2.7 volts). When the voltage obtained by the potentiometer 1 in real time is between U _L and U _H , the angle is measured by the potentiometer 1 at this time; when the voltage value obtained by the potentiometer 1 in real time is outside the threshold, the angle is measured by Potentiometer 2 to measure the angle.

Let the total voltage be U ₀ , the real-time voltage obtained by potentiometer 1 is U ₁ , and the real-time voltage obtained by potentiometer 2 be U ₂ . When the voltage obtained by potentiometer 1 in real time is within the threshold, that is, U _L ≤ _{U 1} ≤ U _H :

$\mathrm{<span\; class="notranslate">\; \&theta;</span>}<span\; class="notranslate">\; =</span>\frac{{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; -</span>{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; L</span>}}}{{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; 0</span>}}}<span\; class="notranslate">\; \&times;</span>\mathrm{<span\; class="notranslate">\; 360</span>}<span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; )</span>$

When the real-time voltage obtained by potentiometer 1 is outside the threshold, that is, when U ₁ <U _L or U ₁ >U _H :

$\mathrm{<span\; class="notranslate">\; \&theta;</span>}<span\; class="notranslate">\; =</span>\frac{{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; 2</span>}}<span\; class="notranslate">\; -</span>{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; 2</span>}\mathrm{<span\; class="notranslate">\; B</span>}}<span\; class="notranslate">\; +</span>{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; h</span>}}<span\; class="notranslate">\; -</span>{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; L</span>}}}{{\mathrm{<span\; class="notranslate">\; u</span>}}_{\mathrm{<span\; class="notranslate">\; 0</span>}}}<span\; class="notranslate">\; \&times;</span>\mathrm{<span\; class="notranslate">\; 360</span>}<span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; )</span>$

Among them, θ - azimuth, zero scale can be corrected according to the actual installation position;

U _2B - the voltage value of potentiometer 2 when the voltage measured by potentiometer 1 is U _H , and this value can be accurately measured.

After θ is calculated, the relative azimuth is obtained. After the equipment is installed on the anti-aircraft gun and corrected by zero scale, the actual azimuth of the anti-aircraft gun can be obtained.

The use process after the installation of the device of the present invention:

Install the device and sensors on the anti-aircraft gun, turn on the power switch, and check the indicator lights. After the indicator lights are normal, the device has entered the real-time automatic detection of the azimuth and elevation angles of the anti-aircraft gun. At this time, the anti-aircraft gun can be operated. At the same moment when the cannon completes the first shot operation, it will automatically record the start time of the operation and the azimuth and elevation angle of the shell, and start the timer at the same time. If there is no operation within 20 seconds (this time can be set according to needs), it will be The last operation time is recorded, and the start and end time of this operation, the azimuth and elevation angle data of each shell are transmitted to the management center through SMS or TCT/IP. The whole process, except dealing with the switching power supply, the rest of the process is completed automatically.
