Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Referring to fig. 1 and 2, an embodiment of the present invention provides a method for identifying a gun inspection action, including:
s1, acquiring the gun model of the gun to be tested, and calling and pre-storing standard gun testing audio signals corresponding to the gun model in the system from the system;
s2, sending out a gun checking password;
s3, acquiring an audio signal to be identified in the gun checking process;
and S4, comparing the audio signal to be identified with the standard gun checking audio signal, judging whether the gun checking action is completed, if so, outputting the gun checking action to be completed, and otherwise, sending a repeated gun checking instruction.
As a further improvement, referring to fig. 2 together, in step S1, the standard gun-shooter audio signal includes: the impact sound of each part of the gun in the standard gun checking process. The curve in fig. 2A (volume on ordinate) is a standard audio signal for a 81 rifle, which is mainly composed of part of a clip for detaching, a sleeve for pulling, a sleeve for self-returning, and a clip for loading. Further, the serial number of the gun to be checked can be acquired. The gun model and the serial number can be stored in the system in advance, and the gun checking history of the gun is recorded in the system.
As a further improvement, the standard gun-test audio signal comprises: the impact sound of each main part of the gun in the standard gun testing process and the time interval. In one embodiment, the impact sound of the cartridge clip and the sleeve is included.
As a further improvement, the main components include a cartridge clip, a trigger, and a safety.
In step S3, an audio signal to be identified in the gun-testing process is acquired by the microphone array. Further, the microphone array is used for acquiring the audio signals, and extracting the audio signals with the distance within a preset threshold range as the audio signals to be identified by analyzing the distance between the microphone array and the gun to be tested. The microphone array at least comprises two microphones, and the distance between the two microphones is 2-3 cm. The microphone array constitutes a short-distance 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 the action specification of the gun test if the distance is within a preset threshold range, wherein the preset threshold range is 3-10cm in the embodiment. Therefore, the microphone array is used for extracting signals of which the satisfied distance is within a preset threshold range from the audio signals and providing the signals to the audio contrast device. If the action of the gun test is standard, the microphone array outputs an audio signal to be identified, and if the action of the gun test is not standard and the action is too large or too small, the microphone array outputs a null signal.
As a further improvement, in step S4, the step of comparing the audio signal to be recognized with the standard gun-testing audio signal and determining whether the gun-testing action is completed includes:
s41, judging whether the impact sound of the main part in the audio signal to be identified is consistent with the impact sound of the main part of the standard gun-checking audio signal, if so, judging that the gun models are consistent and entering S42, and if not, judging that the gun models are inconsistent and sending a repeated gun-checking instruction;
and S42, judging whether the time interval of the impact sound of the main part in the audio signal to be identified and the time interval of the impact sound of the main part of the standard gun-checking audio signal are within a preset range, if so, outputting the gun-checking action to be completed, and otherwise, sending a repeated gun-checking instruction.
Referring to fig. 2, in step S41, the impact sound (curve B) of the main component is substantially consistent with the standard audio signal of the gun test, and if yes, it is determined that the model of the firearm is 81-type rifle. In addition, the impact sound is consistent, and the gun testing action of the gun tester on the corresponding gun is also indicated to be completed.
In step S42, if the time intervals of the impact sounds of the main components are different greatly, it indicates that the gun action of the gun inspector is too slow and does not meet the standard, and therefore, a repeat gun inspection command is issued. Therefore, the method can also be used for carrying out standardized examination on the gun inspector.
As a further refinement, after step S42, the method further includes:
and S43, sending abnormal reasons to a gun inspector, wherein the abnormal reasons comprise gun model inconsistency or gun inspection action nonstandard.
As a further improvement, after the output gun-checking action is completed, the method further comprises the following steps:
and S5, judging whether the frequency of each impact sound in the audio signal to be identified exceeds the frequency setting range of each impact sound in the standard gun-checking audio signal, and if so, judging that the gun is aged or abnormal.
As the guns are produced in a standardized manner, the impact frequencies of the same parts are basically the same, and therefore, the gun aging or the gun abnormity can be judged by judging whether the frequency of each impact sound in the audio signal to be identified is beyond the frequency setting range of each impact sound in the standard gun-testing audio signal. In other embodiments, the frequency of each impact sound of the firearm (each firearm is numbered) can be further recorded, and the gun aging or abnormal condition can be judged through the change of the frequency of each impact sound of the firearm.
As a further improvement, the frequency of each impact sound in the standard gun-test audio signal comprises the impact frequency of an empty cartridge clip and the impact frequency of a real cartridge clip.
As a further improvement, in step S5, the method further includes:
and S6, judging whether the cartridge clip is an empty cartridge clip or a live cartridge clip according to the impact frequency of the cartridge clip in the standard gun-checking audio signal.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made without departing from the spirit and principle of the present invention shall fall within the protection scope of the present invention.
