Problems solved by technology

This method has the following disadvantages: 1) The output voltage of the induction coil is very small—about tens of microvolts. Such a small voltage increases the shooting dead zone: that is, the signal is too small to cause the back-end circuit to count, which causes the weapon Unavailable in some regions of the world
This will lead to more complex processing circuits at the back end

Abstract

The invention provides a one-circle double-pulse revolution cycle number counting method for an airburst fuse. A revolution cycle number counting circuit adopted for the one-circle double-pulse revolution cycle number counting method is arranged in a bullet. The revolution cycle number counting circuit comprises a magnetic electron chip, an operational amplifier and a waveform conversion module. The waveform conversion module comprises a comparator A, a comparator B, a resistor R11, a resistor R13, a resistor R14, an isolation resistor R12, a diode D1 and a diode D2. The operational amplifier is used for receiving sinusoidal signals transmitted by the magnetic electron chip in the bullet, amplifying the sinusoidal signals and transmitting the amplified sinusoidal signals to the waveform conversion module. The waveform conversion module converts sinusoidal waves amplified by the operational amplifier into square waves. The revolution cycle number counting module is used for counting the number of square waves output by the waveform conversion module, and therefore the revolution cycle number of the bullet is obtained. The output voltage of the magnetic electron chip is high, and therefore the region adaptability of a weapon is greatly improved. The two comparators of the waveform conversion module compose a window comparator, and therefore each sinusoidal wave can be converted into two of the square waves.

Description

technical field [0001] The invention relates to a single-cycle double-pulse revolution counting method for an air-explosion fuze, which belongs to the technical field of non-contact fuzes such as air-explosion fuzes and proximity fuzes. Background technique [0002] After the shell projectile or grenade projectile is launched, its range can be determined according to its number of revolutions. Theoretically, after the rotating projectile exits the muzzle or barrel, the flight distance of the projectile is related to the number of revolutions of the projectile, and the number of revolutions has a linear relationship with the range, but has nothing to do with the initial velocity. Therefore, the explosive point of the projectile can be determined by setting the number of revolutions of the projectile— —That is, the fixed-distance detonation is realized by the method of counting the number of revolutions. [0003] The technology widely used at present is to apply the induction...
