In 015, the number of deaths in traffic accidents in the United States was 32,000, and the number of deaths in firearms was 33,000. In the United States, the number of deaths from fire accidents has surpassed the number of traffic accident deaths since 2015.

According to the US Centers for Disease Control and Prevention, the number of deaths from traffic accidents has decreased by 22% from 2005 to 2010, and the number of deaths from firearms has been increasing since 2000. The total number of deaths from firearms accidents dropped to 2,8393 in 2000 after peaking at 3,666 in 1993, but increased again, reaching 3,1328 in 2010.

Incidents related to firearms continue to increase in the United States and around the world. In order to investigate the cause of an accident in relation to a firearm, the cause of the accident must be judged by using the statements of the parties involved or surrounding CCTV video data.

However, if there are no other people around the accident site than the person involved in the accident, or there is no CCTV image of the accident site, there is a problem that it is impossible to accurately determine the cause of the accident.

The firearm 100 includes a firearm and ammunition 15, the gun body assembly 11, the gun assembly 12, the cylinder assembly 13, the ejector assembly 14, the tumbler assembly 16, and the trigger assembly (17). The smart module 200 includes a body 210, hardware 220, and software 230.

Referring to FIG. 3, a block configuration diagram showing the configuration of a functional block for performing an electronic function mounted in the smart module of FIG. 2,

The PC application 240 is externally connected to the storage unit 237 to perform various functions, but includes a shooting information output unit 241 for outputting shooting information and a map location output unit 242 for outputting a map location. .

Referring to Figure 4, as a flow chart for explaining the schematic functional operation of the smart module for a firearm according to the present invention,

After the step (S2) of determining whether or not misrecognition is determined, if the misrecognition is not determined, the step (S4) of detecting the impact amount is performed, and when the amount of impact is detected, the step of detecting the sound amount (S6) is performed. When performing, when the volume is detected, the angle and GPS are then calculated (S18), and then the launch information is stored (S10).

Referring to Figure 5, Figure 5 is an explanatory diagram for explaining the impact boundary value detection process of the smart module for a firearm according to the present invention,

Describes the technique of obtaining firearm impact when using a firearm.

First, an acceleration sensor value is acquired through the acceleration sensor 232. As data output from the acceleration sensor 232, acceleration values for the X, Y, and Z axes are indicated in the +/- direction.

Subsequently, a differentiation process is performed through the differentiator 4, but the value of the acceleration sensor 232 must converge to zero except for the direction of the earth's gravity in a stop situation, but chattering occurs due to an error in the sensor itself.

Differentiation by the differentiator 4 eliminates this chattering phenomenon and makes it possible to detect meaningful data only when detecting acceleration sensor values for multiple directions.

Reference numeral 6 denotes a low-pass filter, and most of the data measured through this have a frequency component. Particularly, when integrating high-frequency data, previous data may accumulate and data may diverge, and a low-pass filter is used to prevent such a case.

Reference numeral 8 denotes an integrator, and the data of the acceleration sensor 232 is sampled at a rate of about 100 s/s. In this case, when the data component is faster than 100 hz, accurate sampling is difficult, and thus, it is accumulated for about 50 samples. The integral is measured in real time. The integral value is exemplarily shown as in FIG. 6. This will be explained further. The reason for integrating in a certain time unit is that the peak value of the acceleration sensor generated when the gun is fired vibrates instantaneously below 1/100 second. In this way, if the holding time of the peak value is short, an effective value is not detected or difficult, so a number of sample values are integrated and used. Since 50 samples accumulate vibration values for 0.5 seconds, the shape of the cumulative value gradually increases and decreases again, resulting in a mountain-like graph.

In this way, the detection of the impact boundary value proceeds, and the impacts generated when using a firearm are variously measured in real ammunition (a), non-lethal ammunition (b), and horror ammunition (c). It judges whether or not it is launched.

In general, the impact amount is in the order of real ammunition> non-lethal ammunition> horror bomb.

Referring to Figure 7, it is a graph for explaining the maximum value extracted from the firearm smart module according to the present invention. When the firearm is fired, the maximum value of the cumulative integral occurs at a certain point in time within 0.5 seconds, and it is difficult to synchronize and process this point in time when processing data in the smart module. Thus, it is necessary to maintain the maximum value for a certain period of time. In the smart module, since the maximum value for 20 seconds of 20 samples is continuously calculated, a rhombic data format similar to FIG. 7 is extracted.

8, as an explanatory diagram for explaining the sound boundary value detection process of the firearm smart module according to the present invention,

Describes the technique for acquiring sound values generated when using a firearm.

Sound (21) refers to the sound that is generated around the gun or firearms. That is, it contains sounds that are generated in addition to firearms.

Since the sound is in an analog form, it is difficult to process in the arithmetic system, so it is digitally converted through the digital converter 22. Since this process is the ADC value according to the sound change, it is different from the frequency conversion used in voice recording. Thereafter, since the ADC data is mixed with noise values, it must be removed from the filter 23 before accumulating the data size in the integrator 24.

The filtered ADC data is accumulated in the integrator 24 to measure the data in real time.

In the sound boundary value detection process, the sound boundary value is used to classify the volume of sound generated when using a firearm. In the smart module, the sound threshold value (the sound is input through the Condensor MIC, the value is converted into a voltage, and the ADC (Analog to Digital, analog voltage is converted into a digital value), and then discretely digitized. After integrating the data in the same way as the impact boundary value detection, the maximum value is calculated and extracted in the form of FIGS. 6 and 7.

The detection of whether to fire a firearm for one acceleration sensor or one sound value has a high probability of false recognition, so both values are used. The above process determines whether or not recognition is made when the impact amount recognition unit 2361 and the sound volume recognition unit 2362 of FIG. 3 are satisfied at the same time.

The volume of the sound is shown in the order of real bullet >= horror bullet> non-lethal bomb.

Referring to Figure 9, as an explanatory diagram for explaining the longitude / latitude output process of the smart module for a firearm according to the present invention,

It shows the technology of obtaining latitude and longitude through GPS.

In the process of recognizing the GPS value 32, the process proceeds to the next step only when the recognition 31 is completed through the shock value (shock boundary value detection 10) and the sound value (sound boundary value detection 25). (See FIG. 4).

In the longitude/latitude calculation process 33, the controller 235 (Micom) in the smart module 200 acquires data through GPS and serial communication.

In the longitude/latitude output process 34, the location information is recorded, and if the application is used later, the location can be confirmed on the map.

10, as an explanatory diagram for explaining the external shock misrecognition determination process of the firearm smart module according to the present invention,

As a technique for preventing erroneous recognition due to external impact, it can be performed by the erroneous recognition preventing portion 2363 of FIG. 3.

The acceleration sensor value, that is, the gravity acceleration value 42 for carrying, aiming, or dropping a firearm is measured through the acceleration sensor 232.

Thereafter, data due to a sensor error is removed through the filter 43.

Then, in the gun aiming stable value calculation process 44, 50 real-time sample data is used to calculate the three conditions that occur before, after, and after the actual shooting to determine the misrecognition (45).

Referring to Figure 11, it is a graph for explaining the stable value of the smart module for a firearm according to the present invention. Please explain the graph (??)

12, as an explanatory diagram for explaining the gun direction output process of the smart module for a firearm according to the present invention,

It relates to a technique for calculating the firing angle of a muzzle when using a firearm. This process may be performed by the angle calculation unit 2364.

The angle calculation is used by measuring the acceleration of the X, Y, and Z axes with an acceleration sensor. Gravitational acceleration can be expressed by calculating the vector sum of the X, Y, and Z axes.

In the graph of FIG. 14, the calculation of the total angle of attack is possible because the acceleration value (accX) of the X axis can be calculated by g cos θ, and vice versa.

θ = atan (accY / accZ) can be calculated simply.

However, since this calculation does not consider the 3D Z-axis, proper calculation results cannot be obtained when the gun is tilted left and right.

By applying the proposed method, considering the 3D Z-axis,

θ= atan( accX / sqrt( accY^2 /accZ^2))

Can be used as

At this time, the θ value is the Radian value, and the constant value of 57.2957795131 is shown below.

Degree =θ* 57.2957795131

When used, it is possible to calculate an appropriate angle value.

Let's look at the acceleration sensor value. Since the acceleration sensor 232 values for the X, Y, and Z axes are always affected by the direction of the Earth's gravity, the vertical direction for the Earth's gravity is always 9.8 m/s^2.

For the acceleration sensor value, a Kalman filter 52 is used, which is used to estimate data for a sensor with a specific distribution of noise unlike a conventional LPF (low-pass filter). By using the Kalman filter 52, the shaking of the angle value due to the inaccuracy of the sensor can be eliminated.

Thereafter, as a gun direction calculation process using the gravity value, it is easy to calculate the gun direction using the value of gravity, but when the smart module is mounted on the actual gun, the X, Y, and Z axes of the sensor are connected to the gravity direction. There are cases where there is no exact match.

To correct this, set the initial value for the sensor direction before angle measurement, calculate the angle through Y value calculation, and then calculate the angle value for the X axis when the measurement range is exceeded.

Thereafter, as the gun direction output process, when the direction of the sensor coincides with the direction of gravity, only the Y-axis is used, and if necessary, correction is performed using the X-axis value.

13, as an explanatory diagram for explaining the output process of the PC application of the smart module for a firearm according to the present invention,

When using a firearm, the technique of storing the firearm's cumulative water repellency is described.

Examine the process of detecting gun use. When the use of a firearm is detected, the date/time (55), longitude/latitude (34), firearm direction (angle) (54), impact value (10), and sound value (25) measured when the firearm is used are EEPROM (Storage: 237 ).

In the recorded data, 200 usage records are stored (72), and when all 200 records are recorded, the oldest data is sequentially deleted and new data can be recorded.

Describes the PC Application connection process. In order for the user to check the recorded data information, the smart module is disconnected from the initial stage, and then the microUSB cable is connected to the PC, and recognition is completed automatically (73).

After that, you can check the record of the use of firearms with a dedicated PC viewer program.

According to the present invention, a smart module for a firearm and a method for acquiring firing information, the use of the firearm by storing the use time, the firing angle, the location of use, and the cumulative water repellency for the time when the real, non-lethal, and horror bombs used in the firearm are triggered is stored.
