Description

Rocket projectile firing number accurate counting method

Technical Field

The invention relates to a counting method, in particular to a rocket projectile firing number counting method.

Background

When weather is affected, the catalyst is sent into cloud layer by adopting the mode of launching rocket shell, thus realizing the functions of rain enhancement and hail suppression. During operation, the number of the launched rocket projectiles has a great influence on the operation quality, and the number of the rocket projectiles is strictly controlled because the rocket projectiles belong to initiating explosive devices, so that the projectile consumption of the operation at each operation point is required to be recorded in real time.

Disclosure of Invention

In view of the above, the present invention provides a method for precisely counting the number of rocket projectiles, which can precisely count the number of used rocket projectiles in the process of rocket projectile launching.

The rocket projectile firing number accurate counting method specifically comprises the following steps: the method comprises the following steps of counting the number of the used rockets in the rocket projectile launching process by detecting the overload of rocket projectile launching equipment, and specifically comprises the following steps:

before the on-orbit rocket projectile is ignited, the overload of rocket projectile launching equipment is measured, the measured value is W, and when the W is smaller than a set value D, the rocket projectile is not launched at the moment;

the starting time of the rocket projectile is set as t1, and the ending time of the rocket projectile is set as t2; after the on-orbit rocket projectile is ignited, measuring the overload of rocket projectile launching equipment again at the time t3, and enabling the measured value to be V and the time interval between t1 and t3 to be set; when V is greater than the set value E, the acceleration for launching the rocket projectile is considered to be applied to the rocket projectile;

after the time interval is set, measuring the overload of the rocket projectile launching device again at the time t4, and if the overload is smaller than the set value D at the time t4, considering that the rocket projectile is launched successfully; then 1 is added to the number of shots fired.

The method also comprises the steps of resistance measurement and detection:

before igniting an on-orbit rocket projectile, firstly measuring the resistance of the orbit of the rocket projectile, enabling the measured resistance to be X, and when the X is in a set resistance range (A, B), considering the rocket projectile to be on orbit and entering the next step; otherwise, the orbit is considered to have no rocket projectile;

after the on-orbit rocket projectile is ignited, measuring the orbit resistance again to enable the measured resistance to be Y, and considering that the rocket projectile is successfully launched when Y is larger than a set value C;

and when the detection result of the overload of the rocket projectile launching device and the detection result of the resistance detection are both 'successful rocket projectile launching', adding 1 to the rocket projectile launching number.

the following are satisfied between t1 and t 3: 5ms < t3-t1<50ms; the following are satisfied between t3 and t 4: t4-t3<3S.

The beneficial effects are that:

(1) When the rocket is launched in a pulse ignition mode, the rocket launching process is judged through the change of the overload quantity, and whether the natural ignition condition is met is judged through the pulse ignition and the change of the overload time sequence, so that the accurate counting of the rocket projectile launching number is realized, and the artificial counterfeiting condition is eliminated.

(2) The accuracy of counting the number of rocket launches can be further ensured by matching the resistance detection with the overload detection.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The embodiment provides a technical method for accurately counting the launched rocket projectiles in the artificial precipitation and hail suppression processes.

The method specifically comprises two parts of resistance detection and overload detection.

1. Resistance measurement and detection

1.1, measuring the resistance of a track where the rocket projectile is located through an AD acquisition circuit, enabling the measured resistance to be X, and considering that the rocket projectile is in track when the X is in a set resistance range (A, B), namely meeting A < X < B, and entering the next step; otherwise, the orbit is considered to have no rocket projectile;

1.2, a 200ms ignition pulse is given to the rocket projectile to ignite the on-orbit rocket projectile; the rocket projectile is made to be ignited at the starting time of t1, the ignition ending time of t2, and the interval between t1 and t2 is about 200ms; as shown in fig. 1;

1.3, after ignition is finished, measuring the track resistance again to enable the measured resistance to be Y, and when Y is larger than a set value C, namely Y > C is met, taking the rocket projectile as derailment (successful firing).

2. Overload detection

2.1 measuring the overload (acceleration amount) of the rocket projectile launching device before ignition, making the measured value be W, and when W is smaller than a set value D, namely W < D, considering that no rocket projectile is launched at the moment;

2.2, after the on-orbit rocket projectile is ignited, measuring the overload of the rocket projectile launching device again at the moment t3, wherein 5ms < t3-t1<50ms is satisfied between t1 and t3, as shown in figure 2, the measured value at the moment t3 is V, and when V is larger than a set value E, namely V > E, the rocket projectile is considered to be launched by acceleration;

2.3 measuring the overload of the rocket projectile launching device again at the time t4, wherein t4-t3<3S is satisfied between t3 and t4, and if the overload becomes smaller and smaller than the set value D at the time t4 as shown in fig. 2, the rocket projectile is considered to be derailed (the launch is successful).

When the judgment results of the resistance detection and the overload detection are the rocket projectile derailment (successful launch), the number of the launched rocket projectiles is increased by 1, namely, the rocket projectiles are regarded as being launched once, so that the number of the launched rocket projectiles can be accurately counted.

In summary, the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
