Description
Technical Field
The invention relates to the technical field of target event judgment, in particular to a shooting event realization judgment method.
Background
In the shooting detection, accurately detecting the occurrence of a shooting event is important for ammunition management and the guarantee of the safety of a target range. Traditional detection methods mainly rely on manual observation and measurement, and have certain subjectivity and error.
In early shooting event detection techniques, a separate shock detection method was often employed. The principle of the method is based on that the firearm generates vibration signals during the shooting process, and whether a shooting event occurs can be judged by detecting the signals. However, due to the many disturbances in the actual environment, such as vibration disturbances caused by the loading of the cartridge and pulling of the bolt, the separate vibration detection methods are prone to false alarms and false detections.
Shock detection is also one of the common methods in early shooting event detection techniques. Shock refers to a pressure wave generated when an object is subjected to a sudden impact, which can propagate over time and space. During a firing event, the exit of the bullet may generate a shock wave that may be detected by a sensor. When shock waves are adopted alone to detect shooting, the shooting is often interfered by other factors in the environment, such as natural phenomena of wind noise, rain noise and the like, or artificial activities such as vehicle passing, personnel walking and the like. These interfering factors may all generate shock signals, resulting in false positives.
The vibration detection or shock wave detection technology is adopted independently, so that certain limitations exist, and false detection is easy to generate. Therefore, it is necessary to develop a method for comprehensive vibration and shock detection to improve the accuracy of shooting event detection.

Detailed Description
Embodiments of the technical scheme of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present invention, and thus are merely examples, and are not intended to limit the scope of the present invention.
It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.
As shown in fig. 1, a shooting event implementation discrimination method includes the following steps:
acquiring shooting information of a gun and hit information of a target plate;
judging the realization result of the shooting event according to the shooting information and the hit information;
and outputting the shooting event judgment result to a visual display module for display.
In the scheme, the new method can judge shooting events more accurately by comprehensively utilizing two kinds of information of vibration and shock wave, and improve detection accuracy and reliability. The novel method can better distinguish vibration differences generated by operations such as cartridge clip loading, bolt pulling and the like and shooting events and shock differences between adjacent target shooting and target shooting by the novel method by collecting and analyzing vibration signals and shock signals of firearms simultaneously, and effectively reduces false alarm and false detection rate.
More specifically, the shooting information of the gun is obtained by collecting the detection value of a vibration sensor arranged on the gun, and the hit information of the target plate is obtained by collecting the output signal of a shock wave target-reporting module arranged on the target plate.
The specific data items detected by the vibration sensor typically include: vibration amplitude during shooting, vibration frequency during shooting, vibration duration during shooting, and possible muzzle up-and-down jitter conditions; whereas the specific data items detected by the targeting module typically include: the location of the shot hit, the accuracy of the hit, the time stamp of the hit.
As shown in fig. 2, more specifically, the method for collecting the detection value of the vibration sensor installed on the firearm specifically includes the following steps:
acquiring parameter data of the gun, wherein the parameter data comprise propulsion parameters and barrel length of the gun;
obtaining a detection value of a vibration sensor arranged on a gun, and comparing the waveform of the detection value with a standard waveform corresponding to the gun in a waveform library, wherein the waveform library stores shooting waveforms corresponding to a plurality of guns and meeting shooting occurrence standards and a plurality of other waveforms not meeting the shooting occurrence standards;
and if the waveform of the detection value is inconsistent with the shooting waveform, filtering the detection value.
The gun can be identified and authenticated by comparing the waveform of the detection value with the standard waveform library established in advance, wherein the standard waveform library stores the shooting waveforms which meet the shooting occurrence standard, and meanwhile, the gun also comprises other waveforms which do not meet the shooting occurrence standard.
More specifically, when judging the implementation result of the shooting event according to the shooting information and the hit information, the method specifically includes the following steps:
acquiring hit data in the hit information, wherein the hit data comprises the number of the hit information and the occurrence time of the hit information;
if the shooting information is consistent with the hit data, judging that the shooting event is realized;
if the shooting information is inconsistent with the hit data, the shooting event is judged not to be realized.
The case where the shooting information is inconsistent with the hit information includes the following cases: when the occurrence time of hit data detected by the target board is earlier than the occurrence time of shooting information; when the number of hits detected by the target plate is greater than the number of shots, the time period can be adaptively set according to the bullet firing rate and the distance between the gun and the target plate, and is generally set to be within 0.1 to 0.5 seconds.
More specifically, if the shooting information is consistent with the hit data, the method specifically further includes the following steps when it is determined that the shooting event is implemented:
acquiring on-site environmental parameters as first data when a gun shoots, and acquiring gun parameters as second data;
inputting the first data and the second data into a process model for calculation to obtain process time as an output result;
acquiring the time difference between shooting information and hit information, and if the process time and the time difference are different; and judging that the shooting event is not realized, and judging that the shooting time is realized if the process time is the same as the time difference.
Here, the shooting information is consistent with hit data, including the following two conditions: the occurrence time of hit data detected by the target board is later than the occurrence time of shooting information; when shooting for multiple times, the number of hit data detected by the target board is less than or equal to the number of shooting information, wherein the acquisition time of the number of hit data of the target board is from the occurrence of the first shooting number to the occurrence of the last shooting data;
by combining the on-site environment parameters with the gun parameters and comparing the process time with the time difference between the shooting information and the hit information, more accurate shooting event realization condition judgment can be obtained. This helps to improve the reliability of the shot data.
More specifically, the process model is specifically represented by the following formula:
wherein v is the on-site wind speed when shooting, θ is the included angle between the shooting direction and the on-site wind direction, s is the distance between the gun and the target plate, q is the gun propulsion parameter, l is the gun barrel length, t is the process time, and g is the gravitational potential energy.
