Description
Technical Field
The invention relates to the technical field of shooting training equipment, in particular to a system and a method for measuring the quantity of ammunition launched by an automatic rifle.
Background
Currently, army organization light weapon firing practice flows are more, and links such as ammunition firing, bullet pressing and firing practice consumption are included, so that real problems and potential safety hazards such as inaccurate ammunition land consumption quantity statistics, mismatching of ammunition firing quantity and actual consumption quantity, bullet pressing omission, private ammunition storage and the like exist. The existing statistical method mainly records the ammunition consumption and shooting time of each time of targeting manually, but when firing continuously, the interval time of each firing is shorter, so that the workload generated by adopting a manual recording mode is larger, and the problems of pen errors, false recording and the like are easy to generate. Once the number of ammunition dispensed and the actual number of consumed are found to be mismatched after the firing is completed, it is difficult to trace the lost ammunition through manually recorded data. If the lost ammunition cannot be recovered in time, the firing practice is greatly affected and serious safety hazards are caused.
On the other hand, it is necessary to define the progress of the use of the firearm (here mainly the number of shots made by a single firearm) before the firing of the firearm is organized and after the firing of the firearm is completed. Although officers and soldiers may perform firearm maintenance on a regular basis, barrel bore rifling erosion and wear may increase as the number of projectiles increases, and the process is irreversibly altered. The damage of the inner bore can cause the ballistic performance of the projectile to change, and then the problems of low initial velocity, low shooting precision, large elliptical porosity and the like can occur, so that the statistics of the total amount of ammunition consumed by the firearm and the monitoring of the service life of the gun barrel become very important. In the prior art, the total amount of ammunition consumed by each gun is recorded manually, and because the personnel is not fixed and the statistics work is not continuous in each training, particularly when shooting continuously, the manual recording is easy to cause inaccurate recording, and a user cannot accurately grasp the use progress of the gun, so that the condition of out-of-limit use of the gun occurs, and the training potential safety hazard is caused.

Further, the system also comprises a two-dimensional code generation module which is arranged on the rifle and connected with the data storage module, and the two-dimensional code generation module is used for generating a two-dimensional code containing rifle number information and rifle projectile data information; the system also comprises a code scanning module, wherein the code scanning module is used for acquiring rifle numbers and rifle projectile data by scanning the two-dimensional codes generated by the two-dimensional code generating module.
When the shooter finishes training and returns the firearm, the firearm management needs to acquire the number of shots (ammunition consumption) of the shooter and compare the number of shots with the number of ammunition dispensed to ensure that there is no ammunition missing or private ammunition. When a firearm is put in storage, the two-dimensional code generating module arranged on the firearm generates a two-dimensional code containing rifle number information (rifle number is stored in the two-dimensional code generating module in advance) and rifle projectile data information, and a manager can acquire the number and projectile times of returning the firearm only by scanning the two-dimensional code through the code scanning module, so that the working efficiency of returning the firearm is improved.
Further, the system also includes a second data storage module coupled to the code scanning module, the second data storage module configured to store rifle numbers and rifle projectile data acquired by the code scanning module.
And the rifle number and rifle projectile data corresponding to the rifle are recorded in the second data storage module, and when the historical shooting data of the firearm is required to be checked, the rifle shooting data can be directly called from the second data storage module, so that the rifle shooting data has traceability, and the convenience of data checking is improved.
Further, the system also comprises a data processing module, wherein the data processing module is connected with the second data storage module; the data processing module is used for acquiring rifle numbers and rifle projectile data stored by the second data storage module and calculating the total projectile times of a single rifle based on the rifle numbers and rifle projectile data.
In the using process of the gun, the firing of each bullet can cause a certain degree of abrasion to the gun barrel, when the gun barrel is abraded to a certain degree (namely, beyond the service life of the gun barrel), the problems of low initial speed, low shooting precision, large elliptical hole ratio and the like can occur, so that the total projectile times of the rifle are required to be counted in time in the gun management process, and whether the gun can be used continuously or not can be determined.
Further, the system also comprises an early warning module, wherein the early warning module is connected with the data processing module; and the early warning module is used for comparing whether the total projectile number of the single rifle is larger than the theoretical total projectile number of the rifle, and if so, early warning information is generated.

In accordance with another aspect of the present invention, there is provided a method of metering the quantity of ammunition fired by a rifle, comprising the steps of:
s1: the Hall sensor, the signal processing module, the first data storage module and the two-dimensional code generation module are arranged on the rifle;
s2: the Hall element acquires the periodic variation of the magnetic induction intensity at the machine handle and generates an electric signal at a corresponding moment;
s3: the signal processing module judges whether the action corresponding to the electric signal is caused by manual pulling or bullet firing according to the electric signal, and if the judgment result is caused by bullet firing, the step S4 is entered;
s4: adding 1 to the number of projectiles in rifle projectile data and storing the time of bullet firing;
s5: repeating the steps S2-S4 until the shooting is finished.
In the technical scheme, when the handle of the rifle does not move and the magnetic induction intensity sensed by the Hall element does not change, the handle is in a static state, and the fact that the shooter does not pull the handle or complete firing is indicated; when the magnetic induction intensity sensed by the Hall element is changed, the movement of the handle is indicated, and the movement of the handle can be manually pulled or the movement of the handle can be driven by bullet firing. The movement of the machine handle is judged to be caused by manual pulling or bullet firing through processing and analyzing the electric signals, so that whether one bullet firing is completed or not is judged, and if one bullet firing is completed, the number of the secondary bullet firing is counted into the number of the projectiles (namely, the number of the projectiles is increased by 1); the steps are repeated until the shooting training is completed, and the accurate statistics of the number of the projectile in the shooting training process can be completed.
Further, the method for judging whether to pull by manpower or fire by bullets in the step S3 is as follows:
s301: obtaining the actual movement speed of the rifle handle according to the electric signal;

s303: the actual movement speed of the comparison machine handle is matched with the first theoretical movement speed and the second theoretical movement speed respectively, and if the actual movement speed is matched with the first theoretical movement speed, the bullet firing is indicated; if the actual movement speed matches the second theoretical speed, the human force pulling is indicated.
According to the using characteristics of the gun, in some special cases, the machine handle is required to be pulled by manpower, and the machine handle also moves along with the machine handle in the bullet firing process, but the speed (second theoretical movement speed) of manually pulling the machine handle is obviously smaller than the autonomous movement speed (first theoretical movement speed) caused by bullet firing, so that whether the machine handle movement is the manual pulling or the autonomous movement accompanied by bullet firing can be distinguished according to the movement speed of the machine handle.
Further, the method further comprises:
s6: generating a two-dimensional code containing rifle numbers and rifle shooting data;
s7: scanning a two-dimensional code to obtain projectile data of single training of the rifle, comparing whether the number of projectiles of single training (namely ammunition consumption) is matched with the number of issued ammunition, and if not, generating early warning information; storing the single training projectile data in a second data storage module;
s8: the total number of shots for a single rifle is calculated based on the rifle number and rifle projectile data in the second data storage module.
Gun warehouse management personnel acquire rifle numbers and rifle shooting data through scanning the two-dimensional code, and whether the ammunition consumption of single training accords with the ammunition release amount is compared, thereby avoiding the occurrence of potential safety hazards such as ammunition loss or private storage. Meanwhile, projectile data of the rifle are stored in the second data storage module, so that subsequent data analysis and statistics are facilitated.
Further, the method further comprises:
s9: and comparing the total projectile number of the single rifle with the theoretical projectile number of the rifle, judging whether the total projectile number of the single rifle is larger than the theoretical projectile number of the rifle, and if so, generating early warning information.

Detailed Description
The following description of the embodiments of the present invention will be made in detail and with reference to the accompanying drawings, wherein it is apparent that the embodiments described are only some, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Example 1
As shown in fig. 1, the present embodiment provides a system for measuring the amount of ammunition fired by an automatic rifle, comprising a bullet firing detection module comprising a linear hall sensor disposed on the rifle body, said linear hall sensor comprising a cylindrical ferromagnetic magnet disposed in the rifle bolt shank hole and a hall element disposed in the upper recess of the handle of the rifle bolt (as shown in fig. 2); the system also comprises a signal processing module, wherein the signal processing module is connected with the Hall element and is used for judging whether the rifle completes a projectile or not and generating rifle projectile data through sensing signals of the Hall element; the system also comprises a first data storage module, wherein the data storage module is connected with the signal processing module, and the data processing module is used for storing rifle projectile data, and the rifle projectile data comprises projectile times and corresponding time of each shooting.
Taking a 95-type or 95-1-type automatic rifle as an example, the rifle bolt comprises a machine handle, and the middle lower part of the machine handle comprises a machine handle hole with the diameter of 0.9 cm and the depth of 0.8 cm. The cylindrical ferromagnetic magnet is embedded in the handle hole, and the size of the cylindrical ferromagnetic magnet is attached to the handle Kong Qiahao without slipping. The Hall element and other components are stuck in the groove at the upper part of the handle of the wood guard on the 95 type automatic rifle and the 95-1 type automatic rifle.
During firing, the Hall element detects the position of the cylindrical ferromagnetic magnet in the hole of the handle (the working principle of the linear Hall sensor is shown in figure 3), and the movement condition of the handle is obtained according to the regular periodic movement of the handle. Because the gun machine is linked by the emission of the supersonic speed projectile, the detection of the bullet emission condition can be realized through the position of the cylindrical ferromagnetic magnet in the machine handle hole.
Specifically, when the automatic rifle launches a supersonic flying projectile, the machine handle and the automatic machine move at a high speed, and the displacement of the magnetic field formed by the ferromagnetic magnet is continuously changed. In the reciprocating motion process, the magnetic induction intensity in the Hall element is periodically and obviously changed and is converted into an electric signal with regular change.
Taking a 95-1 automatic rifle as an example, the single combat speed is 40 beats/min, and the theoretical speed is 650 beats/min and the combat speed is 100 beats/min when shooting continuously. The distance of displacement of the handle of the 95-type or 95-1-type automatic rifle during shooting is 11.5 cm. Because the speed, frequency and force law of the manual pulling machine handle are obviously different from the autonomous movement of the machine handle along with the rifle in single shot or continuous shot, the signal processing module can distinguish the manual pulling and the autonomous movement along with bullet firing through the analysis and processing of the electric signals, and acquire the information of bullet shooting quantity, bullet shooting time and the like. When the sensing module detects a periodic, regular reciprocation, it counts for 1 shot.
The single-shot combat speed is 40 beats/min; during continuous shooting, the theoretical shooting speed is 650 beats/min, the combat shooting speed is 100 beats/min, and the single-pass displacement distance of the machine handle is 0.115 m. The trigger drives the handle to reciprocate for 1 time, so that the firing of 1 bullet can be completed. But the movement rule and the instantaneous speed of the gun machine are consistent whether the single shot or the continuous shot is adopted. Thus, when firing 1 round of rifle, the handle reciprocation time should be less than 1/650= 0.001538 minutes, about 0.092307 seconds, i.e. handle reciprocation time t Reciprocating movement The method meets the following conditions:
at the completion of the movement of course x of about 0.23 m during this time, the instantaneous minimum average velocity v of movement of the bolt movement ave_min About:
and the shooter manually completes the process speed v of pulling and pushing the gun muzzle Manual operation About 0.307 to about 0.575 m/s, the instantaneous average rate of movement of the bolt movement is about:
thus, it can be determined whether the projectile is completed based on the rate of movement of the handle.
As a preferred embodiment, the linear hall sensor is an ASIC linear hall sensor.
The ASIC type linear Hall sensor has stable circuit structure and can eliminate offset voltage of the Hall element. The offset voltage and the magnetic field voltage are separated in the frequency domain by combining the circuit module and the operational amplifier, the direct current offset is modulated into a high-frequency signal, the high-frequency signal is filtered by a post-stage low-pass filter circuit, the accurate magnetic field voltage is output, the higher sensing precision is realized, and the offset voltage is eliminated by 90% through simulation verification.
The ASIC type linear Hall sensor realizes the dynamic adjustment function of sensitivity. A user can program a chip through VCC and VOUT pins, interact with the EEPROM with high integration level and store a calibration value, and an internal digital circuit calculates the value to generate a corresponding adjustment signal so as to realize dynamic configuration of sensitivity and static point voltage. The sensitivity adjustment range is 0.6-14.8 mV/G, the initial quiescent point voltage is set at 1/2 of the supply voltage, and the typical adjustment range is 2-3V.
The ASIC type linear Hall sensor has a digitally compensated system architecture, and improves the temperature characteristic of sensitivity. When the working temperature changes, the internal processor of the chip calculates the correlation coefficient stored in the EEPROM according to a temperature compensation formula, and generates a compensation signal to change the operational amplifier gain in the analog signal path, thereby realizing temperature drift compensation of the sensitivity of the Hall element. The test result shows that the sensitivity temperature drift of the Hall sensor is controlled to be +3% within the range of-40 ℃ to 150 ℃, and the linearity of the error within 1% can be ensured when the sensitivity is less than 85 mV/G.
Therefore, the linear Hall sensor can accurately detect and identify the high-frequency, high-speed and continuous movement of the rifle bolt in a single shot and continuous shot state, and further obtain the number of the shots consumed by the rifle.
When the rifle is in a single shot state, 1 bullet is filled into the bore by manually pulling the rifle bolt before shooting for the first time, and then a trigger is triggered to shoot; the remaining shots are completed by pulling the trigger. In the shooting process, the bullet only completes firing when the trigger is triggered, and meanwhile, the trigger drives the cylindrical ferromagnetic magnet in the trigger handle to conduct orderly and regularly reciprocating motion. When the single shooting is adopted, the time interval of pulling the trigger is equal to the time interval of the reciprocating motion of the gun camera, at the moment, the motion of the cylindrical ferromagnetic magnet in the handle is characterized by independent discontinuity, the magnetic induction intensity of each motion is periodically changed, and the change of the magnetic induction intensity is further converted into discontinuous electric signals. Therefore, the signal processing module can obtain the number of periodic reciprocating motions by analyzing and processing the electric signals generated during single shooting, the number of the periodic reciprocating motions is the number of the shot ammunition, and the shot condition of the ammunition is detected.
When the rifle is in a continuous firing state, 1 bullet is filled into the bore by manually pulling the rifle bolt before the first shooting, and then the trigger is triggered to shoot, the short shot (2-5 shots) and the long shot (6-10 shots) can be implemented. All shots are completed by simply pressing the trigger long. When the bullet is continuously fired, the gun camera drives the cylindrical ferromagnetic magnet in the bolt shank to perform continuous and uninterrupted regular reciprocating motion. At the moment, the movement of the cylindrical ferromagnetic magnet in the handle is characterized by continuity and uninterrupted, and the change of the magnetic induction intensity is further converted into a continuous electric signal. Therefore, the signal processing module can obtain the number of periodic reciprocating motions by analyzing and processing the electric signals generated during the firing, the number of the periodic reciprocating motions is the number of the ammunition to be fired, and the firing condition of the ammunition is detected.
When the gun is rapidly checked, the gun machine is manually and continuously and rapidly pulled, the method for detecting the bullet shooting condition comprises the following steps: when the manual gun pulling machine is used for quick gun inspection, the reaction speed of a person is about 0.1 second, and the displacement time for pulling the gun pulling machine to perform 0.115 m is added, so that the speed is obviously greater than that of single shot or point shot, namely the speed is not in a speed interval corresponding to the single shot or point shot, and the bullets are not fired in the gun inspection process, so that the shot number of the bullets is always 0.
When the rifle is in a stuck shell and an empty warehouse hanging machine, the method for detecting the bullet shooting condition comprises the following steps: when the shell is stuck, the shell in the firearm cannot be withdrawn to influence the emission; when the empty bin hangs, the bullet in the bullet bin is emptied, the bullet supporting plate is jacked up by the spring, and then the device is driven to hang the gun. In both cases, the ferromagnetic magnets in the bolt and the bolt shank hole are not displaced nor fire the bullets, so the number of detected bullets is 0.

When the shooter finishes training and returns the firearm, the firearm management needs to acquire the number of shots (ammunition consumption) of the shooter and compare the number of shots with the number of ammunition dispensed to ensure that there is no ammunition missing or private ammunition. When the firearm is put in storage, the two-dimensional code generating module arranged on the firearm body generates a two-dimensional code containing rifle number information and rifle projectile data information, and a manager can acquire the number and projectile number of returning the firearm only by scanning the two-dimensional code through the code scanning module, so that the working efficiency of returning the firearm is improved.
