Description

FUZE HAVING SENSOR FOR MEASURING ROTATION AND METHOD FOR BULLET VELOCITY CORRECTION OF TIME-DATA USING THEREOF}

The present invention relates to a fuse, and more particularly, the actual rotation signal of the warhead being triggered and in flight is obtained by the rotation detection sensor, and the actual bullet speed of the bullet is measured based on the rotation signal, and based on the actual bullet speed The present invention relates to a fuse having a built-in rotation sensor for correcting time data inputted in a microprocessor, and a method of correcting time velocity of time data using the same.

In general, mechanical and chemical fuses in ammunition are largely divided into impact functions that explode and collide with targets, and time functions that explode by a set time. Electronic fuses include mechanical and chemical fuses, and the proximity of electric fuses. The function is added.

These electronic fuses are being used for air explosives, and if you look briefly at the process of detonation of the bombs with the electronic fuses, if the distance to the target is measured by the laser range finder, the time or number of revolutions of the warhead will be The fire control system enters the fuse and then fires it, then explodes in midair when the fuse reaches the distance set.

Here, an error occurs between the target position data input from the fire control device and the position where the air explosive bombs are actually detonated, and there is a time-loading type as a method for correcting the error.

Conventional time-filling method is to measure the bullet velocity of the warhead deviated from the barrel and to correct the final position data based on this, and to measure the number of revolutions of the constantly rotating warhead to correct the final position data based on this have.

In the conventional fuse and bullet speed correction method of measuring the bullet speed and correcting the data, as shown in FIGS. 1 and 2, the initial time data input from the fire control apparatus 20 is corrected by the measured actual bullet speed. The fuse 10 may include a demodulation circuit 12 for converting analog initial time data into a digital signal and a microprocessor 14 for inputting initial time data converted into digital signals from the demodulation circuit 12. It was made to include.

In addition, a modulation circuit 16 provided for communication between the microprocessor 14 and the fire control device 20 is further included in order to confirm the accuracy of the initial time data input to the microprocessor 14.

In addition, the initial time data input to the demodulation circuit 12 is charged to the capacitor (not shown) via the charging circuit 18, and then electricity is supplied to all components that require power in the fuse 10. .

On the other hand, the device for measuring the actual bullet speed of the warhead 30, the magnet 32 installed on the outer surface of the warhead 30, the data receiving coil 34, the barrel for guiding the flight of the warhead 30 ( On the outer surface of the adapter 50 mounted at one end of the 40, a pair of coil velocity measuring coils 52 wound around the barrel 40 at a predetermined distance and a rear of the coil velocity measuring coils 52 The data transmission coil 54 wound by a predetermined length is included.

When the device is used and the process of correcting the initial time data stored in the fuse 10, specifically the microprocessor 14 from the fire control device 20 based on the measured actual bullet speed, first, the fire control device ( The analog initial time data received from 20 is digitized in the demodulation circuit 12, and this digital initial time data is input to the microprocessor 14 and then fire control with the microprocessor 14 through the modulation circuit 16. When the initial time data was confirmed by recommunication between the devices 20, the initial time data was finally stored in the microprocessor 14.

Next, when the initial time data is input to the microprocessor 14, the magnet 32 is paired while the warhead 30 passes through the adapter 50 while flying under the guidance of the barrel 40. A signal related to the actual speed of the warhead 30 was generated while passing the coil velocity measuring coil 52 at a time difference, and the time data was analyzed by the fire control apparatus 20 based on this signal, and then data was transmitted. Through the connection of the coil 54 and the data receiving coil 34, the fire control apparatus 20 was finally inputted to the microprocessor 14 via the demodulation circuit 12.

Therefore, the detonation of the warhead 30 was controlled by the time data that was corrected based on the measured actual bullet speed and then finally input to the microprocessor 14.

However, in order to measure actual speed for correcting time data, a separate adapter 50 equipped with a coil speed measuring coil 52 and a data transmitting coil 54, as well as the coil speed measuring coil 52 and data transmission, are provided. In order to interact with the coil 54, a plurality of components for measuring the velocity of the bullet, such as the magnet 32 and the data receiving coil 34, installed in the warhead 30, were installed.

In addition, since communication for measuring, correcting, and inputting the actual bullet speed of the warhead 30 is performed for a very short time during which the warhead 30 passes through the adapter 50, the communication from the ball speed measurement until the corrected time data is inputted. Phase error occurred, and the winding length of the data transmission coil 54 became longer as the winding length of the data transmission coil 54 became longer. In particular, the measurement of the bullet speed and the correction of the time data by the measured bullet speed and the corrected time data Since a series of processes in which the storage and the like are performed separately and then transmitted by communication must be performed for a short time, there is a problem that the previous process has a great influence on the subsequent process despite the serious communication error.

The present invention has been made to solve the above problems, a rotation speed sensor, a ball speed measurement circuit for calculating the actual speed of the warhead on the basis of the actual rotation signal of the warhead obtained by the rotation sensor, and the speed measurement circuit and The fuse is configured to include a microprocessor connected to correct the initial time data input from the fire control device and to finally store the corrected time data, thereby measuring the rotation signal obtained by the ball speed measurement and correcting the time data based thereon. And a series of processes are processed in a fuse at a time, and the rotation signal obtained from the rotation sensor is measured at the speed of the bullet so that the bomb of the final shot is made based on the speed of the bullet. Fire control for correction of time data made in the ball speed measurement circuit and microprocessor While it is excluding the communication between the fuse level and it is an object to provide a cost to remove an error caused by who communicate during the flight of the bullet rotation detecting sensor is embedded fuse.

In order to achieve the above object, a fuse incorporating a rotation sensor according to the present invention includes a demodulation circuit in which time data is received from a fire control device, and a micro time in which time data digitally converted in the demodulation circuit is input. A processor, a rotation sensor installed in connection with the demodulation circuit to detect the rotation of the flying warhead, and a bullet speed installed to measure and transmit the actual flight speed to the microprocessor based on the rotation signal output from the rotation sensor. The measurement circuit is included.

In addition, the demodulation circuit is installed to convert the analog rotation signal obtained from the rotation detection sensor into a digital rotation signal, and to transfer the converted rotation signal to the ball speed measurement circuit.

In addition, the microprocessor is installed to correct and finally store timed data on the basis of the actual speed of the bullet output from the ball speed measurement circuit.

On the other hand, the method for correcting the time data by acquiring the rotation signal of the warhead in flight, the initial time data from the fire control device is input to the microprocessor (S10); The rotation of the bullet in flight is detected by the rotation sensor to obtain an analog rotation signal (S20); Converting the analog rotation signal into a digital rotation signal in a demodulation circuit (S30); A step of measuring actual bullet speed in the bullet speed measurement circuit based on the converted rotation signal (S40); The measured actual shot speed is compared and analyzed with the shot speed data inputted to the microprocessor, and the time data is corrected and stored (S50).

The rotation sensor is installed to output the actual rotation signal of the warhead in analog, and transmit it to the demodulation circuit.

The demodulation circuit is installed to convert the analog rotation signal transmitted from the rotation detection sensor into a digital rotation signal, and transmit it to the ball speed measurement circuit.

In addition, the ball speed measurement circuit is installed to measure the actual flight speed of the warhead using the time difference of the digital rotation signal transmitted from the demodulation circuit, and transmit it to the microprocessor.

The microprocessor corrects initial time data input from the fire control device based on the actual flight speed of the warhead transmitted from the ball speed measurement circuit, and finally inputs the final time data, and controls the detonation of the warhead by the final input data.

Therefore, the analog signal about the actual rotation of the warhead obtained from the rotation sensor is converted into a digital signal in the demodulation circuit, and then measured at the flight speed of the actual warhead in the ball speed measurement circuit. The input time data is corrected, and finally, the detonation of the warhead is controlled based on the time data input corrected by the microprocessor.

Here, the rotation signal output from the rotation sensor is used to measure the actual bullet speed, and ultimately, the warhead detonation is made by time data corrected based on the actual bullet speed of the warhead.

According to the present invention configured as described above, when the actual rotation signal of the warhead output from the rotation detection sensor is input to the ball speed measurement circuit through the demodulation circuit, the actual speed of the warhead is measured in this speed measurement circuit, and the actual speed By correcting the time data previously input from the microprocessor, the actual bullet speed is measured in a state where communication between the microprocessor and the fire control device is excluded, then the time data is corrected, and the time data input to the microprocessor is corrected. The communication between the microprocessor and the fire control system, which was made during the flight of the bullet, is eliminated, eliminating the communication errors that occurred during the conventional warhead flight, and eliminating a number of components including the adapter for measuring the conventional bullet speed. The cost is reduced.

Based on the accompanying drawings, a fuse having a rotation sensor according to a preferred embodiment of the present invention will be described in detail.

3 is a side cross-sectional view schematically illustrating a state in which a warhead having a fuse having a speed sensor for rotation speed correction according to the present invention passes through a barrel, and FIG. 4 is a flow of time data input and corrected in the fuse of FIG. 3. 5 is a diagram illustrating a rotation signal generated by the rotation sensor of FIG. 3, and FIG. 6 is a time-based data corrected based on an actual rotation signal of the warhead obtained by the rotation sensor of FIG. 2. The process to be stored is the flow chart shown.

First, as shown in Figures 3 and 4, the fuse 100 is a built-in rotation sensor according to the present invention is a rotation sensor 110 for outputting the actual rotation of the warhead 300 in flight as an analog signal, The demodulation circuit 120 converts the analog rotation signal output from the rotation detection sensor 110 into a digital rotation signal, and the warhead 300 in flight based on the rotation signal converted by the demodulation circuit 120. It includes a carbon speed measurement circuit 130 for measuring the actual speed, and a microprocessor 140 for correcting and storing the time data inputted based on the actual speed measured by the carbon speed measurement circuit 130.

The rotation sensor 110 outputs the rotation of the warhead 300 in flight as a sine wave signal, the sinusoid is installed to be transmitted to the demodulation circuit 120.

In addition, the demodulation circuit 120 is installed so that the power is sent to the charging circuit 150 of the initial time data received from the fire control device 200, the explosion specifications to the microprocessor 140, the rotation sensor The analog sine wave signal transmitted from 110 is converted into a digital sine wave signal, and then installed to be transmitted to the ball speed measurement circuit 130.

Here, a modulation circuit (not shown) for communication with the fire control apparatus 200 may be further configured to check the initial time data input to the microprocessor 140.

The bullet velocity measurement circuit 130 measures the actual flight speed of the warhead 300 based on the digitally converted sinusoidal signal received from the demodulation circuit 120, and the measured actual velocity is measured by the microprocessor 140. It is installed to be transmitted.

In addition, the microprocessor 140 corrects and stores the time data previously input from the fire control apparatus 200 based on the actual bullet speed transmitted from the bullet speed measurement circuit 130.

Here, the fire control device 200 is a position for the target of the warhead 300 and the flight distance of the warhead 300, the flight speed of the warhead 300, the detonation position of the warhead 300, the detonation of the warhead 300 Initial time data is generated by collecting and analyzing information such as time.

In addition, the initial time data generated by the fire control device 200 is a fuse embedded in the warhead 300 at various time points, such as before or after the warhead 300 is charged, the warhead 300 is flying. Is sent to 100.

The transmission of this time data is performed in the conventional manner, that is, during the flight of the warhead 300 through the transmission / reception coil wound on the warhead 300 and the adapter 50 (FIG. 1), or the warhead 300 is transferred to the chamber. Before or after loading may be made through a separate transmission and reception terminal, it can be made using a variety of other methods and the like.

However, when the initial time data is input to the fuse 100 from the fire control device 200, the communication between the fire control device 200 and the fuse 100 is cut off, which is a fire control device for correcting the initial time data ( This is because re-communication between the 200 and the fuse 100 is unnecessary.

Therefore, the rotation signal obtained from the rotation detection sensor 110 is analyzed and measured through the demodulation circuit 120, the ball speed measurement circuit 130, the microprocessor 140, and the like, and then time data is corrected and stored. The process is performed inside the fuse 100 and has nothing to do with the fire control device 200.

Here, a general bullet is largely divided into a casing portion and a warhead 300 portion, and the fuse 100 is mounted on the warhead 300, and the fuse 100 is a head which is the front of the warhead 300. ), Of course, it can be mounted on the middle part (middle part) and the back part (middle part).

On the other hand, the rotation sensor 110 outputs a sinusoidal signal shown in Figure 5 from the rotation of the warhead 300 in flight, the sinusoidal signal is a wave 'w' of one cycle while the warhead 300 is flying It appears that the time 't' is taken while it occurs.

Looking at the sinusoidal signal, it takes time 't ₁ ' to complete a wave 'w ₁ ' of one cycle with respect to the sinusoidal signal indicated by a specific warhead 300 is flying, the wave 'w ₂ ' of one cycle there is completed, and also it takes a time 't _2', there is also the wave of one period 'w _3' completed and also the time it takes 't _3'.

Although the warhead 300 manufactured by the same process has different bullet speeds in each of the warheads 300 flying, the bullet speed of the warhead 300 has a close relationship with the rotation of the warhead 300, so that the rotation signal of the warhead 300 is transmitted. If obtained, the actual bullet speed of the warhead 300 may be measured, and the time data is corrected based on the measured actual bullet speed.

Therefore, the surge means, and the wave is longer 'w _3' compared to the wave 'w _1' it is a short 'w _1' wave 'w _2' relative to the much is tansok the faster it mean that much is tansok is slow do.

Comparing these waves 'w' with respect to the time 't' can measure the actual flight speed of the warhead 300, and this measurement is made in the ball speed measurement circuit 130.

The coal velocity measuring circuit 130 analyzes the wave 'w' and the time 't' with respect to the input rotation signal after the analog rotation signal output from the rotation detection sensor 110 is digitally converted in the demodulation circuit 120. The bullet speed is measured, and the measured actual bullet speed is transmitted to the microprocessor 140.

In addition, the microprocessor 140 corrects the time data previously input based on the actual bullet speed input from the ball speed measurement circuit 130 and finally inputs the detonation of the warhead 300 through the time input data. To control.

In the process of processing the rotation signal obtained from the rotation sensor 110, as shown in Figure 4, the rotation signal for the wave 'w' and the time 't' output from the rotation sensor 110 is output as analog After being transmitted to the demodulation circuit 120, when the rotation signal is digitally converted in the demodulation circuit 120 and input to the carbon speed measurement circuit 130, the wave 'w' and time 't' in the carbon speed measurement circuit 130 'To compare and analyze the flight speed of the actual warhead (300), and the actual bullet speed measured in this way is transmitted to the microprocessor 140, and the time data entered is corrected based on the actual bullet speed. Time data is finally stored in the microprocessor 140.

On the other hand, the rotation signal obtained from the rotation sensor 110 is measured at the actual speed of the warhead 300, the correction method of the fuse 100 is built in the rotation sensor 110 is configured to be input is shown in FIG. As shown, step S10 of the initial time data for the target from the fire control device 200 is input to the microprocessor; Generating an analog rotation signal through the rotation detection sensor 110 with respect to the rotation of the warhead 300 while flying (S20); An analog rotation signal generated by the rotation detection sensor 110 is transmitted to a demodulation circuit 120 and then converted into a digital rotation signal (S30); A digital rotation signal is input to the ball speed measurement circuit 130 and then the flight speed of the actual warhead 300 is measured (S40); The time data is corrected and finally stored in the microprocessor 140 based on the actual shot speed measured by the shot speed measurement circuit 130 (S50).

Initial time data input to the microprocessor 140 is made through the communication between the fire control device 200 and the microprocessor 140, the communication between the fire control device 200 and the microprocessor 140 is warhead ( Before or after the 300 is charged, and the warhead 300 may be performed in various ways, such as through a transmission / reception coil or a transmission / reception terminal.

In addition, the communication between the fire control device 200 and the microprocessor 140 is preferably made before the flight of the warhead 300.

This is because the correction of the time data according to the flight speed of the warhead 300 is made by itself inside the fuse 100 separately from the fire control device 200, so that the fuse (00) and fire that occurs when the warhead 300 is in flight This is to exclude the communication error between the control device 200.

Therefore, the process of collecting, correcting and storing the data to correct the time data during the flight of the warhead 300 is released, that is, the actual rotation signal of the warhead 300 is generated (S20), the rotation signal is digital The step S30 is converted to (S30), the actual bullet speed is measured based on the digital rotation signal (S40), the time data is corrected based on the actual bullet speed and stored in the microprocessor 140 (S50), etc. Apart from the 200, the fuse 100 is made in itself.
