The gun model obtaining device is arranged in the sound insulation chamber and is used for obtaining the model of the gun to be inspected; further, the gun model acquisition device comprises one or more of a keyboard input device, an image acquisition device and a sound input device. In this embodiment, the gun model of the gun to be checked can be input through the keyboard input device by an operator, and the gun model can be obtained by matching through the image acquisition device, such as a camera, shooting a picture of the gun, and the gun model can be informed through voice input by the operator directly.
The sound recording device comprises a microphone array, wherein the microphone array is used for acquiring the audio signals in the sound insulation chamber, analyzing the distance between the microphone array and the gun to be inspected, and extracting the audio signals with the distance within a preset threshold range as the audio signals to be identified; the recording device of this embodiment sets up in the sound-proof chamber indoor for record the sound in the sound-proof chamber, obtain the sound that each part collision sent in the inspection gun in-process, and output to audio frequency comparison device. Meanwhile, the microphone array at least comprises two microphones, and the distance between the two microphones is 2-3cm. The microphone array constitutes a short-range voiceprint recognition device. The microphone array analyzes the time difference between the microphones by comparing the respective audio signals, converts the time difference into the distance between the center point of the microphone and the gun, and determines that the gun is standard in operation if the distance is within a preset threshold range, wherein the preset threshold range is 3-10cm in the embodiment. Thus, the microphone array is used to extract signals of the audio signals that satisfy a distance within a preset threshold range, and provide the signals to the audio comparison device. If the action of the gun is standard, the microphone array outputs an audio signal to be identified, and if the action of the gun is not standard, the action is too large or too small, the microphone array outputs an empty signal.
The audio comparison device is used for storing a standard gun checking audio signal database associated with guns of different types and is used for calling standard gun checking audio signals of the types of guns to be checked, comparing the audio signals to be identified with the standard gun checking audio signals and judging whether gun checking actions are completed or not.
Further, the audio comparison device is specifically configured to retrieve a standard gun-checking audio signal of a model of a gun to be checked, compare the audio signal to be identified with the standard gun-checking audio signal, determine whether a necessary impact sound of the audio signal to be identified is consistent with a necessary impact sound of the standard gun-checking audio signal, and determine that a time interval between the necessary impact sounds of the audio signal to be identified is within a predetermined range, if yes, determine that the gun-checking action is completed.

Referring to fig. 1, in the standard gun audio signal database, the standard gun audio signal includes: the necessary impact sound of each component of the firearm during standard gun tests. The A curve (the ordinate is the volume) in figure 1 is the standard gun checking audio signal of the 81 rifle, which mainly comprises cartridge clip disassembly, sleeve pulling, self-returning sleeve, cartridge clip assembly and the like.
Furthermore, the gun model obtaining device can obtain the model of the gun to be inspected, and the standard gun inspection audio signal of the model of the gun to be inspected is called from the database through the audio comparison device. The standard gun inspection audio signal comprises: the firearm made the necessary impact sound and non-impact sound during standard gun tests.
Further, the necessary impact sounds include at least a clip, a trigger, a sleeve, and a safe impact sound, and the non-crashable sound includes at least a trigger impact sound.
In this embodiment, the standard gun inspection audio signal of the 81 rifle is mainly composed of five parts, namely, cartridge clip disassembly, sleeve pulling, sleeve self-returning, cartridge clip assembly and trigger touching. The cartridge clip is detached, the sleeve is pulled, the sleeve is automatically returned, the cartridge clip is installed as necessary impact sound, namely, an operator needs to touch the impact sound in the gun checking process and the impact sound sent by a corresponding part of the gun in the touch process, and if the impact sound is absent in the gun checking process, the conditions of missed checking, out-of-place gun checking action and the like of the operator are possibly caused; the trigger is not crashable sound in the process of gun checking, the finger of an operator must protect the protective cover of the gun and the trigger cannot be touched by the finger, because the trigger is likely to be wrongly touched by the operator once touching the gun, meanwhile, in the process of gun checking, if the gun checking staff does not protect the protective cover of the gun, the trigger can be wrongly touched by the hand-over staff in the process of gun transferring, the trigger has multiple pressure, the initial pressure is minimum, the gun checking staff can be wrongly touched, the sound can be generated after the wrong touch, and if the crashable sound occurs in the process of gun checking, the trigger can be wrongly touched by the operator, and the gun checking process is judged to be unqualified at the moment.
Therefore, the system can also be used for carrying out standardized assessment on gun inspection personnel.
Further, the standard gun audio signal comprises: the firearm is the time interval between the necessary impact sounds during standard gun tests. In the gun inspection process, the sound generated by each part which is required to be touched not only judges whether an operator touches the part, but also has an important parameter, namely, the time interval between the necessary impact sounds, firstly, the time interval between the steps in the operation process of the operator is required to be limited in a certain time, secondly, if each step has a certain operation standard, the time interval is required to be limited until each action is finished until the impact sound is emitted, and the time interval is limited, so that whether all the gun inspection actions of the operator are finished and whether the gun inspection number measurement of the operator reaches the standard can be primarily judged.
Further, the gun further comprises a frequency comparison device for judging whether the frequency of the necessary impact sound in the audio signal to be identified exceeds the frequency setting range of the necessary impact sound in the standard gun inspection audio signal, and if so, judging that the gun is aged or abnormal.
Since the guns are all produced in a standardized manner, the impact frequencies of the same components are also substantially the same, and therefore, the gun aging or abnormality can be judged by judging whether the frequency of each impact sound in the audio signal to be identified is out of the frequency setting range of each impact sound in the standard gun inspection audio signal. In other embodiments, the frequency of each impact sound of the firearm (each firearm is numbered) may be further recorded, and the change of the frequency of each impact sound of the firearm is used to judge whether the firearm is aged or abnormal.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. 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.
