Description

Bullet number system

Technical field

The utility model relates to bullet counting technology fields, and in particular to a kind of bullet number system.

Background technique

Existing bullet counting technology is not bullet number system truly, but cartridge counter.It is this Cartridge counter only simply counts bullet, and there is no the management for carrying out systematization.

Existing cartridge counter mainly has following 2 kinds of modes: 1, being counted using the vibration of gun barrel.I.e. cartridge counter On gun barrel, counted in emission bullet using the sharp pounding signal of gun barrel.2, it is counted using Hall sensor.That is handle Cartridge counter on the gun barrel, when being projected in gun barrel using bullet on Hall sensor caused electromagnetic induction signal into Row counts.

The common disadvantage of aforesaid way is as follows: 1, must change the weight of gun body cartridge counter on gun barrel Amount and structure influence normally to shoot experience.2, battery must be housed inside counter, it is therefore necessary to replace battery or charging. 3, it is unfavorable for the system administration of bullet.

In conclusion the utility model devises a kind of bullet number system.

Utility model content

In view of the shortcomings of the prior art, leading to the utility model aims to provide a kind of bullet number system Cross with the contactless installation of gun, avoid influence gun normal shooting, can effectively realize bullet counting accuracy.

To achieve the goals above, the utility model is achieved through the following technical solutions: bullet number system, packet Sound transducer, accurate amplifying circuit, single-chip microcontroller, communication interface circuit and background computer are included, sound transducer passes through on front platform computer Sensor interface be connected with accurate amplifying circuit, accurate amplifying circuit is connected by single-chip microcontroller with communication interface circuit, communication Interface circuit is connected by transmission line with background computer.

Preferably, the front platform computer further includes LM324 amplifier, A/D conversion circuit, sound transducer passes through LM324 amplifier is connected with A/D conversion circuit, and A/D conversion circuit is connected with single-chip microcontroller, and single-chip microcontroller passes through MAX485 serial port circuit It is connected with background computer, A/D conversion circuit uses TLC5510.

Preferably, the sound transducer is free using MYD-1380 there are two the sound transducer settings Field shock pressure sensor, sound transducer acquisition sound simultaneously judge the spatial dimension made a sound and sound characteristic for background computer Value provides initial data.

Preferably, the single-chip microcontroller uses STC12C2052, multiple sensor signal, and accurate recording can be received The time received, the spatial dimension made a sound for background computer judgement provide initial data.

Preferably, the communication interface circuit uses chip MAX485, and by RS485 interface, with background computer into Row communication.

Preferably, the background computer uses PC machine, receive the signal sent of front platform computer, be signal analysis, judgement and The hardware foundation of back-stage management.

The utility model has the following beneficial effects:

1, with the contactless installation of gun.The utility model carries out bullet counting using voice recognition technology.I.e. in target position Two sides more than one sound transducer is installed, without any component contacted with gun, therefore do not influence normally to shoot Experience.

2, using mains-supplied, it is not necessarily to battery.

3, computer control.It realizes bullet and a series of scientific managements such as receives, shoots, recycling, counting.

Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

- Fig. 7 referring to Fig.1, present embodiment use following technical scheme: bullet number system, including sound sensor Device 1, accurate amplifying circuit 2, single-chip microcontroller 3, communication interface circuit 4 and background computer 5, sound transducer 1 pass through the biography on front platform computer 6 Sensor interface 7 is connected with accurate amplifying circuit 2, and accurate amplifying circuit 2 is connected by single-chip microcontroller 3 with communication interface circuit 4, communicates Interface circuit 4 is connected by transmission line 8 with background computer 5.

The sound transducer of present embodiment is more than one sound transducer, and effect is acquisition sound and is The spatial dimension and sound characteristic value that background computer judgement makes a sound provide initial data.Accurate amplifying circuit requires accurately to put Big times and wider frequency band, can be truly reflected the intensity and frequecy characteristic of voice signal, provide for background computer digital filtering Original signal.Single-chip microcontroller is the core component of front platform computer, can receive multiple sensor signal, and accurate recording receive when Between, the spatial dimension made a sound for background computer judgement provides initial data.Communication interface circuit uses RS485 interface, and rear Platform machine is communicated.Background computer uses PC machine, receives the signal that front platform computer is sent, and is signal analysis, judgement and back-stage management Hardware foundation.The working principle of this specific embodiment: as shown in Figure 1:

1, sensors A and sensor B are sound transducer, collected sound signal.

2, voice signal is converted into electric signal through sensor and is transmitted to accurate amplifier.

3, amplified signal is transmitted to single-chip microcontroller by accurate amplifier.

4, single-chip microcontroller received signal and receives time of this signal and through communication interface circuit sends backstage to Machine.

5, background computer judges by analysis, obtain whether be this target position shooting sound.

6, background computer getting, consuming, recycle etc. and be managed to bullet.

Present embodiment can use monophone sound sensor structure.It the advantage is that structure is simple, background computer passes through The intensity identification of identification sound still can distinguish the shot of this target position and close on the shot of target position, eliminate and close on the dry of target position It disturbs.Its shortcoming is that requiring excessively harshness to the analytical judgment of background computer, it is easy to produce erroneous judgement.

More than two sound transducer structure can also be used, as shown in Figure 2.The advantage is that more can accurately judgement sound The range and extraction characteristic value of sound, anti-interference ability is stronger, counts more acurrate.Its shortcoming is that the complexity of hardware and software It significantly improves, cost also correspondinglys increase.

In summary it analyzes, under the target range of only one target position and the more quiet situation of environment, monophone can be used The structure of sound sensor.The structure of 2 sound transducers can satisfy the demand in general target range.In the more severe situation of environment The structure of more than two sound transducer can be used down.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
