    专利说明:

    The invention relates to a device for counting shots delivered by means of a handgun according to the preamble of patent claim 1.
    Handguns usually have no way to detect the shots fired by them. The installation or attachment of a counter on the handgun is a risk factor for the occurrence of a malfunction of the handgun.
    The object of the invention is to capture the votes cast from a handgun shots without having to make changes to the handgun.
    The invention solves the problem with the characterizing feature of claim 1. The advantage is that for detecting the shots no direct attachment of a Schusszählvorrichtung is required on the handgun.
    According to the invention, a device is provided for detecting the shots fired from a handgun. This includes an acceleration sensor configured to measure the acceleration of the hand, a sound sensor configured to measure the sound pressure level of the shot sound, and a processing unit to which the acceleration sensor and the noise sensor are connected and to which the measurement results of the acceleration sensor and the noise sensor, and which is adapted to detect a shot when the respective signals passed by the acceleration sensor and the noise sensor each exceed a predetermined threshold within a predetermined period of time. An inventive device is characterized by a fastening means for, in particular motion-rigid, mounting the acceleration sensor and the noise sensor on a hand and / or on a wrist.
    The device according to the invention therefore advantageously allows to detect the shots fired from a handgun without having to make changes to the handgun. The device is capable of enabling a reliable detection of a shot by combining the measured values of the acceleration of the hand triggered by the firing with the measured values of the shot sound.
    The acceleration sensor is suitable for measuring the acceleration during hand movements. Usually these accelerations are in the range around 1.6g (16m / s2). If a shotgun is fired from a handgun, it recoils with an acceleration of approximately 78.5m / s2. By setting the threshold within a range of 22.5 m / s 2 to 61.5 m / s 2, it is possible to detect an acceleration of the hand exceeding the threshold as a firing.
    The shot produces a bang which is loudest in the immediate vicinity of the handgun and reaches a sound pressure level of approx. 158 dB. To obtain reliable results in commercial handguns, it is advantageous that only a shot is taken when actually shot and when this shot was fired from the handgun in question. In order to meet these requirements, provision may be made for the processing unit to be able to detect a shot when the measured value forwarded by the acceleration sensor exceeds a threshold value of 22.5 m / s 2 to 61.5 m / s 2 and / or that from the noise sensor measured sound pressure level exceeds a threshold between 145 and 155 dB.
    In order to avoid erroneous detection of shots by movements of the shooter and / or by shot sounds of other weapons, it can be provided that the processing unit is adapted to detect a shot when the signal exceeding the predetermined threshold signals of the acceleration sensor and the noise sensor within at most 3 milliseconds lie.
    In order to be able to evaluate the detection of the shots in the simplest possible way, the processing unit can be designed to increase a count when a shot is detected.
    In order to make the meter reading visible to the shooter at any time, a display field for displaying the meter reading can be provided.
    In order to enable an evaluation at a later time, a storage medium may be provided for storing the counter reading.
    For external detection and processing of delivered shots it can be provided that the processing unit is designed to forward the detection of a shot to an external device. Advantageously, in order to protect the sensors, the processing unit and optionally the storage medium and / or the display from external influences such as impacts or moisture, it may be provided that the sensors and the processing unit and optionally the storage medium and / or the display are installed in a common housing are.
    The fastening means for fastening the device to the hand and / or wrist can be designed as a bracelet, in the form of fastening straps or Velcro straps. Preferably, the fastening means may be formed as a glove and acceleration sensor, sound sensor and processing unit may be arranged on the back of the glove, in particular on the side remote from the back of the hand back of the glove. As a result, a particularly reliable detection of the shot is possible, since an immediate proximity to the handgun is made, the acceleration of the hand movement is accurately reproduced and slipping of the device is excluded.
    The acceleration sensor can be designed to determine an acceleration vector having at least two, in particular three, acceleration components, wherein the processing unit is supplied with the signals relating to the individual acceleration components, and the processing unit is designed to generate acceleration components at the same time or within a predetermined time window to compare separately with separate thresholds, and wherein the processing unit is adapted to the case in which one, a predetermined number or all of these threshold comparisons have or have exceeded a threshold value, and also the signal passed by the sound sensor exceeds the predetermined threshold, a shot determine.
    In order to enable a particularly reliable detection of shots, it may be provided that the acceleration sensor is mounted in particular on the back of the glove that the acceleration sensor determines the first acceleration component in the direction of an x-axis, which is aligned parallel to the fingers Acceleration sensor detects the second acceleration component in the direction of a y-axis, which lies in the plane of the back of the hand and is aligned normal to the x-axis, and the acceleration sensor determines the third acceleration component in the direction of a z-axis, which is normal to the x- and y-axis. Axis stands. The individual components of the acceleration vector related to the above-mentioned axes or coordinate directions are approximately in the following ranges when a shot is fired: Acceleration components in the x direction occur in the range from 63.5 m / s 2 to 92.5 m / s 2. Acceleration components in the range of 60.5 m / s2 to 80.5 m / s2 occur in the y-direction. Step in z direction
    Acceleration components in the range of 38 m / s2 to 54 m / s2 on.
    The processing unit may be configured to compare the first acceleration component with a first acceleration threshold that is between 34 m / s 2 and 61.5 m / s 2, the second
    To compare acceleration component with a second acceleration threshold, which is between 30.5 m / s2 and 46 m / s2, and the third
    To compare acceleration component with a third acceleration threshold, which is between 22.5 m / s2 and 34.5 m / s2.
    According to the invention is also a method for detecting the fired from a handgun shots, wherein the acceleration of the hand is measured by means of an acceleration sensor, wherein by means of a noise sensor, the sound pressure level of the shot sound is measured, and wherein the delivery of a shot with the handgun is detected when the from accelerometer and
    Sound sensor each forwarded signals within a predetermined time each exceed a predetermined threshold, characterized in that the acceleration sensor and the noise sensor before the delivery of shots on a hand and / or on a wrist of the shooter, in particular motion-resistant, are attached.
    Advantageously, the delivery of a shot is determined when the measured value passed on by the acceleration sensor exceeds a threshold value of 22.5 m / s 2 to 61.5 m / s 2 and / or the sound pressure level measured by the noise sensor exceeds a threshold between 145 and 155 dB.
    In order to ensure reliable detection, the delivery of a shot is advantageously detected when the signals of the acceleration sensor and the noise sensor which exceed the predetermined threshold are detected within a maximum of 3 milliseconds.
    To facilitate the evaluation, a count can be incremented when the delivery of a shot is detected.
    Advantageously, the counter reading is displayed to the shooter, in particular on a display located in the region of his hand back or wrist, and / or the counter reading is stored or forwarded to an external device.
    Advantageously, the acceleration sensor and the noise sensor on a glove, in particular on the back of the hand glove, preferably on the side remote from the back of the hand back of the glove, are attached.
    Furthermore, an acceleration vector with three acceleration components can be determined and these acceleration components can be compared separately with separate threshold values. In the event that one, a predetermined number or all of these threshold comparisons have or have exceeded a threshold value, and also the signal passed by the sound sensor in each case exceeds the predetermined threshold, then a shot is detected.
    Advantageously, the first acceleration component can be aligned in the direction of a y-axis parallel to the fingers, the second acceleration component can be aligned in the direction of a y-axis which lies in the plane of the back of the hand and is aligned normal to the x-axis, and the third acceleration component in the direction of a z-axis, which is normal to the x and y axis. On the basis of acceleration components generated at the same time or within a predetermined time window, the first acceleration component can then be compared with a first acceleration threshold, which lies between 34 m / s 2 and 61.5 m / s 2, and / or the second acceleration component is compared with a second acceleration threshold which is between 30.5 m / s 2 and 46 m / s 2 and / or the third acceleration component are compared with a third acceleration threshold which is between 22.5 m / s 2 and 34.5 m / s 2.
    The invention is illustrated by the following drawing (Figure 1) without limiting the general inventive concept.
    In Fig. 1, a device according to the invention is shown. The device comprises a fastening means 1, a housing 2, an acceleration sensor 3, a noise sensor 4 and a processing unit 5.
    The fastening means 1 is formed in the embodiment of the invention shown in FIG. 1 as a glove. The acceleration sensor 3, the noise sensor 4 and the processing unit 5 are advantageously arranged on the back of the glove, in particular on the side of the back of the glove facing away from the back of the hand. As a fastener 1 may alternatively be provided a bracelet, straps or Velcro straps that allow attachment of the device especially on the back of the hand or wrist.
    The housing 2 serves as a support for the electronic components and surrounds the sensors 3, 4 and the processing unit 5. Advantageous in this embodiment is the protection of the sensors 3, 4 and the processing unit 5. An alternative embodiment may provide that the electronic components directly in the fastening means 1 are integrated without being surrounded by a common housing 2.
    In the first embodiment of the invention shown in FIG. 1, the acceleration sensor 3 is designed to measure the amount of acceleration of the hand independently of the direction of acceleration and to transmit it as a measuring signal to the processing unit 5. Usually the accelerations of the hand are in the range around 16 m / s2. If a shot is fired from a handgun, the amount of acceleration in the range of 38 m / s2 to 92.5 m / s2 occurs in the course of the recoil movement. The acceleration sensor forwards a detected measured value to the processing unit 5, which compares the relevant acceleration measured value with a predetermined threshold value. The threshold value can be assumed to be between 22.5 m / s2 and 61.5 m / s2, depending on the weapon used.
    The acceleration sensor 3 may, in an alternative embodiment, be designed such that it respectively detects the acceleration separately in the x, y and z directions. Preferably, such an acceleration sensor is mounted on the back of the hand or on the back of the glove, wherein the first axis, hereinafter referred to as the x-axis, is aligned parallel to the fingers. The second axis, hereafter referred to as the y-axis, lies in the plane of the back of the hand and is aligned normal to the x-axis. The third axis, referred to below as the z-axis, is perpendicular to the x-axis and y-axis. The individual components of the acceleration vector related to the above-mentioned axes or coordinate directions are approximately in the following ranges when a shot is fired: Acceleration components in the x direction occur in the range from 63.5 m / s 2 to 92.5 m / s 2. Acceleration components in the range of 60.5 m / s2 to 80.5 m / s2 occur in the y-direction. Acceleration components in the range of 38 m / s2 to 54 m / s2 occur in the z-direction. The acceleration sensor 3 forwards the measured values for the individual acceleration components to the processing unit 5, which compares the relevant acceleration measured value with a threshold value specified separately for the respective axial direction. The threshold for the acceleration component along the x-axis can be assumed to be between 34 m / s2 and 61.5 m / s2, depending on the weapon used. The y-axis acceleration component threshold may be between 30.5 m / s2 and 46 m / s2, depending on the weapon used. The z-axis acceleration component threshold may be between 22.5 m / s2 and 34.5 m / s2, depending on the weapon used. The processing unit 5 can also be designed such that it performs a shot detection even if one of the threshold values is exceeded or only if it exceeds two or three of the threshold values.
    By specifying a threshold value for the acceleration or by specifying threshold values for the individual acceleration components, it can advantageously be achieved that only the acceleration of the hand following a firing will lead to the detection of a shot, but not other hand movements.
    The noise sensor 4 measures the noise level and creates a signal corresponding to the noise level, and transmits this to the processing unit 5. The firing produces a bang that is loudest in the immediate vicinity of the handgun and there is a sound pressure level in the range of about 150 dB 162 dB achieved. The processing unit 5, the measurement signals of the noise sensor 4 are supplied. It compares the measurement signals with a predetermined threshold, which can be selected, for example, between 145 dB and 155 dB, depending on the weapon used. Preferably, a threshold for the sound pressure is selected, which is only slightly below the expected sound pressure at firing. It can be advantageously achieved by prescribing the threshold for the sound pressure level such that no shots originating from other handguns are detected.
    The processing unit 5 continuously, in particular at intervals of less than one millisecond, performs threshold comparisons for the acceleration and sound pressure measurements received by it. A shot is advantageously only recognized as detected if the relevant threshold values for the measured values of the motion sensor 3 and for the measured values of the noise sensor 4 are exceeded within a time window. The size of the time window is advantageously between 1 ms and 10 ms milliseconds. By this measure can be advantageously achieved that only delivered from the handgun concerned shots are detected and there is no erroneous detection by other movements of the shooter or shot sounds of other shooters.
    The processing unit 5 can be designed such that it forwards the detected shots directly to an external device or an external memory. Alternatively or additionally, it can also be provided that the processing unit 5 increases a count when a shot is detected.
    It can also be provided that a display panel visible to the shooter is provided on the device, on which the counter reading is displayed. Also, a storage medium for storing the count can be provided on the device, wherein advantageously a memory card is used as the storage medium.
