It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0046] Figure 1The present invention provides a structural diagram of a gun electric ignition function detection device. Figure 1 As shown, the device comprises:

[0047] A detection electrode, a signal detection unit, a signal acquisition unit and a signal processing unit electrically connected in sequence;

[0048] The detection electrode is used to obtain the electrical firing signal of the artillery;

[0049] The signal detection unit is used to convert the electric ignition signal into an actual first voltage signal;

[0050] The signal acquisition unit is used to acquire the first voltage signal and convert the first voltage signal into a second signal identifiable by the signal processing unit;

[0051] The signal processing unit is used to process the received second signal and output a third signal for determining whether the electric ignition signal is qualified.

[0052] The detection electrode of the present invention can be made of red copper and can be installed at the firing interface of the artillery, corresponding to the position of the firing pin of the artillery. When the artillery electric firing function detection device is installed after the firing interface of the artillery, when the firing pin of the artillery hits the detection electrode, the firing pin of the artillery is connected to the detection electrode, and at this time, the detection electrode transmits the electric firing signal of the artillery.

[0053] The signal detection unit can be a component or a load unit with a certain resistance value, which is used to convert the electric ignition signal output by the detection electrode into an actual first voltage signal for subsequent signal detection. The first voltage signal is a voltage signal across the two ends of the component or the load unit with a resistance value.

[0054] The signal acquisition unit can collect the first voltage signal in real time. For example, it can continuously collect the voltage signal at both ends of the element or load unit with resistance. Then, when the electric ignition signal changes, the corresponding first voltage signal will also change. The signal acquisition unit can obtain the change state of the electric ignition signal within the detection time period, that is, the change of the first voltage signal is the same as the change of the electric ignition signal. In addition, the signal acquisition unit can only realize the function of signal acquisition. It needs to convert the first voltage signal into a second signal that can be recognized by the signal processing unit, so that the signal processing unit can analyze the range and change of the collected signal. The change of the second signal can be equal to or similar to the change of the first voltage signal.

[0055] The signal processing unit is used to receive the second signal, and analyze and process the numerical range of the second signal and the changes in the detection time, so as to output a third signal for judging whether the electric ignition signal is qualified. The third signal can be a signal for indicating whether the electric ignition signal is qualified or unqualified, for example, it can be a high-level signal or a low-level signal; the third signal can be a plurality of signals, which respectively correspond to a plurality of indicators for judging the electric ignition signal, and the indicators may include the duration and amplitude of the electric ignition signal. Then, when the duration and amplitude of the electric ignition signal are qualified, the third signal can output a low-level signal corresponding to the duration and amplitude respectively.

[0056] The technical solution of the embodiment of the present invention is to detect the electric ignition signal emitted by the artillery firing interface through the detection electrode, and the signal detection unit converts the electric ignition signal into an actual first voltage signal, and the signal acquisition unit is used to collect the first voltage signal and convert it into a second signal that can be recognized by the signal processing unit. The signal processing unit processes the received second signal and outputs a third signal for judging whether the electric ignition signal is qualified. On the one hand, the present invention can detect the electric ignition signal, and on the other hand, it can analyze and process the detected signal to judge whether the electric ignition signal is qualified or faulty, so that the electric ignition signal can be quantitatively detected to inform the inspector of the detailed status of the artillery.

[0057] In one embodiment, the detection unit includes a load simulation unit;

[0058] The load simulation unit includes a simulated load, and the simulated load is connected in series with the detection electrode;

[0059] The resistance of the simulated load is equal to the resistance of the ammunition electric primer, or an integer multiple NR of the resistance R of the ammunition electric primer, or 1 / N of the resistance R of the ammunition electric primer, where N is an integer.

[0060] The load simulation unit includes a simulated load, which can be an actual resistor, and can directly measure the resistance of the ammunition primer of the actual artillery, and use the resistance of the ammunition primer as the resistance of the simulated load. Of course, the resistance of the simulated load can also be set to an integer multiple NR of the resistance R of the ammunition primer, or 1 / N of the resistance R of the ammunition primer.

[0061] In such Figure 2 In the structural diagram of another embodiment of the artillery electric firing function detection device shown in the figure, the detection electrode outputs the electric firing signal to one end of the simulated load, and the other end of the simulated load is grounded, that is, a voltage signal is generated at both ends of the simulated load. In this embodiment, since the resistance value of the simulated load is set to the resistance value of the ammunition electric primer, the change of the voltage signal generated by it can feedback the change of the electric firing signal received by the actual artillery and the amplitude.

[0062] In one embodiment, the detection unit also includes a voltage divider unit; the voltage divider unit is connected in parallel to the load simulation unit; the voltage divider unit includes at least two voltage divider resistors connected in series, and the voltage signal across the at least one voltage divider resistor is used as the first voltage signal to output a voltage signal that meets the measurement range of the signal acquisition unit.

[0063] like Figure 3 As shown, since the voltage divider unit is connected in parallel at both ends of the load simulation unit, and the voltage divider unit may include two voltage divider resistors 1 and 2 connected in series, and the signal detection unit is used to detect the voltage across the voltage divider resistor 2, that is, the voltage across the voltage divider resistor 2 is used as the first voltage signal. In this embodiment, the resistance ratio of the voltage divider resistor 1 and the voltage divider resistor 2 can be set according to the actual range of the signal acquisition unit. For example, when the maximum value of the voltage across the simulated load is 10V, and the actual range of the signal acquisition unit is [-1V, +1V], the resistance of the voltage divider resistor 1 and the voltage divider resistor 2 can be set to 9:1, so that the numerical range of the voltage across the voltage divider resistor 2 collected by the signal acquisition unit meets the actual range.

[0064] In one embodiment, the signal acquisition unit includes an analog-to-digital converter; the analog-to-digital converter is used to convert the first voltage signal collected from the signal detection unit into the second signal recognizable by the signal processing unit; the first voltage signal is an analog voltage signal, and the second signal is a digital signal.

[0065] like Figure 2 and Figure 3 In the structural diagram of the artillery electric ignition function detection device shown in the figure, the signal collected by the signal acquisition unit is an analog voltage signal, and when the signal processing unit performs data processing, it uses digital signals for processing, that is, the signal acquisition unit can use an analog-to-digital converter to convert the analog voltage signal into a digital signal that can be recognized and processed by the signal processing unit.

[0066] In one embodiment, it further includes a control unit; the control unit, the signal detection unit, the signal acquisition unit and the signal processing unit are electrically connected in sequence;

[0067] The control unit is used to send a self-test signal to the signal detection unit;

[0068] The signal detection unit is used to convert the self-test signal into a fourth voltage signal;

[0069] The signal acquisition unit is used to acquire the fourth voltage signal and convert the fourth voltage signal into a fifth signal identifiable by the signal processing unit;

[0070] The signal processing unit is used to process the received fifth signal and output a sixth signal for determining whether the system self-check is qualified.

[0071] like Figure 3 The structural diagram of another embodiment of the artillery electric ignition function detection device shown in FIG. Figure 3 The control unit is electrically connected to one end of the first switch K1, and is used to control the opening and closing of the first switch K1. The other end of the first switch K1 is electrically connected to the first end of the simulated load R1, and the second end of the simulated load R1 is electrically connected to the first end of the detection electrode and is in a grounded state. The simulated load R1 is connected in parallel with a voltage divider unit, which includes a first voltage divider resistor R2 and a second voltage divider resistor R3 connected in series, the first end of the second voltage divider resistor R3 is connected to the first end of the detection electrode and the second end of the simulated load R1 and is in a grounded state, the second end of the second voltage divider resistor R3 is electrically connected to the first end of the first voltage divider resistor R2 and the input end of the signal sampling unit, and the second end of the first voltage divider resistor R2 is electrically connected to the first end of the simulated load R1; the output end of the signal sampling unit is connected to the signal processing unit. Among them, the first switch K1 can be a relay or other controllable switch; the signal acquisition unit is an analog-to-digital converter; the control unit and the signal processing unit are both located in the MCU for control and analysis calculation.

[0072] Before the detection electrode starts to detect the electric ignition signal, the artillery electric ignition function detection device turns on the self-test function. The control unit controls the first switch to close and sends a self-test signal to the signal detection unit, which includes an analog load and a voltage divider unit. Since the first switch connects the analog load R1 and the second end of the first voltage divider resistor R2, the first end of the second voltage divider resistor R3 is grounded, and the second end of the second voltage divider resistor R3 is electrically connected to the first end of the first voltage divider resistor R2 and the input end of the signal sampling unit, that is, the signal sampling unit obtains the fourth voltage signal at both ends of the second voltage divider resistor R3; the signal sampling unit can convert the fourth voltage signal into a fifth signal recognizable by the signal processing unit, wherein the fourth voltage signal can be an analog voltage signal, and the fifth signal can be a digital signal; the signal processing unit is used to process the received fifth signal and output a sixth signal for judging whether the system self-test is qualified. Among them, the self-test signal is usually a fixed signal, such as a pulse signal or an analog electric ignition signal, therefore, the received fifth signal of the signal processing unit can be compared with the index threshold set in advance to judge the self-test result. Specifically, when the fifth signal meets the indicator threshold corresponding to the self-test signal, the signal processing unit may output a sixth signal indicating that the system self-test is qualified.

[0073] In one embodiment, the control unit is further used to control the opening and closing of a second switch on the series circuit formed by the detection electrode and the signal detection unit to control the start and end of the ignition signal detection operation.

[0074] When it is necessary to detect the electric ignition signal, the control unit can control the second switch on the series circuit formed by the detection electrode and the signal detection unit to open, and the electric ignition signal is transmitted to the voltage divider circuit of the signal detection unit through the detection electrode and the second switch K2. After the detection is completed, the control unit controls the second switch K2 to be disconnected and wait for the next detection. The second switch K2 can be a relay or other types of control switches.

[0075] In one embodiment, it further includes a power supply unit;

[0076] The power supply unit supplies power to the signal acquisition unit, the signal processing unit and the display unit respectively.

[0077] The power supply unit can be composed of a battery compartment and a power supply circuit. For example, the battery compartment can be installed with 4-5 dry batteries, so that the battery compartment can output a voltage of 6.0V to 7.5V; the battery compartment is electrically connected to the power supply circuit, and the power supply circuit is respectively connected to the signal acquisition, control unit, signal processing unit and display unit. The power supply circuit can convert the 6.0V to 7.5V output by the battery compartment into 3.3V and 5.0V voltages, of which 5.0V is provided to the display unit, and 3.3V is provided to the control unit and the signal processing unit, and the signal acquisition unit.

[0078] In one embodiment, it also includes a working switch and a display unit;

[0079] A first end of the working switch is connected to the signal processing unit, and a second end of the working switch is grounded.

[0080] The display unit responds to the third signal and displays a state corresponding to the third signal.

[0081] like Figure 4As shown in the figure, the display unit includes at least two result display lights, L1 and L2; the first end of L1 and the first end of L2 are both connected to the power supply circuit; the second end of L1 and the second end of L2 are respectively connected to the two third signal output ends of the signal processing unit. In this embodiment, the signal processing unit has at least two third signal output ends. When the signal processing unit is qualified for the first judgment indicator, it can output the third signal that the first indicator is qualified. At this time, the result display light L1 can be controlled to display a green light, otherwise the result display light L1 can be controlled to display a red light; when the signal processing unit is qualified for the second judgment indicator, it can output the third signal that the second indicator is qualified. At this time, the result display light L2 can be controlled to display a green light, otherwise the result display light L2 can be controlled to display a red light. Finally, the display results of the two result display lights L1 and L2 can be combined to determine whether the electric ignition signal is qualified.

[0082] In a specific embodiment, Figure 4 The circuit diagram of the artillery electric ignition function detection device is shown. Figure 4 The power supply unit converts the 7.5V voltage output by the battery compartment into 3.3V and 5.0V voltages, wherein 5.0V is provided to the display unit, and 3.3V is provided to the MCU and the signal acquisition unit, wherein the MCU includes a control unit and a signal processing unit; the first end of the detection electrode is connected to the second end of the analog load R1 and the first end of the second voltage-dividing resistor R3 and is in a grounded state, and the second end is connected to the first end of the second switch K2; the control end of the second switch K2 is connected to the MCU, and the second end of the second switch K2 is connected to the first end of the analog load R1 and the second end of the first voltage-dividing resistor R2; the first end of the first voltage-dividing resistor R2 is respectively connected to the second end of the second voltage-dividing resistor R3 and the input end of the signal acquisition unit, and the output end of the signal acquisition unit is linked to the MCU; the MCU is electrically connected to the first end of the working switch, the second end of the result display lights L1-L4, the control end of the first switch and the first end of the first switch, respectively, the second end of the working switch is grounded, the first ends of the result display lights L1-L4 are all connected to the 5V power interface of the power supply unit, and the second end of the first switch is connected to the first end of the analog load R1.

[0083] During the preparation work, the MCU in the artillery electric ignition function detection device will control the first switch K1 to close and send a self-test signal to the analog load R1. The signal acquisition unit collects the voltage across the second voltage-dividing resistor R3 and converts the voltage signal into a digital signal recognizable by the MCU. The MCU obtains the recognizable digital signal and analyzes and judges it. If the judgment result is that the self-test is qualified, the result signal is output to control the result display light L4 to display green.

[0084] When the electric ignition signal needs to be detected, the working switch is closed, and the detection electrode is connected to the firing interface of the gun. At this time, the MCU controls the result display light L3 to display green, indicating that it is currently in the detection state; after the detection electrode receives the electric ignition signal, the electric ignition signal is converted into a voltage signal at the analog load R1, and converted into an analog voltage signal within the range of the signal acquisition unit through the second voltage divider resistor R3. The signal acquisition unit converts the analog voltage signal into a digital signal and sends the digital signal to the MCU. When the MCU is qualified for the first judgment indicator, it can output a third signal that the first indicator is qualified to control the result display light L1 to display a green light, otherwise the result display light L1 is controlled to display a red light; when the MCU is qualified for the second judgment indicator, it can output a third signal that the second indicator is qualified to control the result display light L2 to display a green light, otherwise the result display light L2 is controlled to display a red light. The staff can judge whether the electric ignition signal is qualified based on the display results of the two result display lights L1 and L2. After the detection is completed, if the electric ignition signal is not received at this time, the result display light L3 will not light up.

[0085] Figure 5 The present invention provides a method for detecting the electric firing function of a gun. Figure 3 As shown, the device comprises:

[0086] S101, receiving sampling data from the signal acquisition unit within a preset sampling time.

[0087] It should be noted that the preset sampling time may be a sampling time T set according to the actual duration of the electrical ignition signal. For example, the sampling time T may be 20 ms or 30 ms, and may also be set by the experimenter.

[0088] S102, respectively calculating the average value of the sampling data in different time periods or the energy of the sampling data in different time periods within the preset sampling time; the sampling data includes sampling point data with non-zero values.

[0089] The preset sampling time can be divided into multiple time periods to measure the changes of signals in different time periods. For example, the preset sampling time can be divided into five time periods, and the sampling data characteristics of each of the five time periods [0, T / 5], [T / 5, 2T / 5], [2T / 5, 3T / 5], [3T / 5, 4T / 5], and [4T / 5, T] are calculated respectively.

[0090] In one embodiment, the average value of the sampled data in each time period may be calculated or the signal in each time period may be integrated to calculate the energy value in the time period, thereby obtaining the voltage average value corresponding to the sampled signal in each time period or the energy value obtained by integrating the voltage. The sampled data is a series of point data, and in this embodiment, data with a value of 0 may be deleted in the sampled data to better calculate the voltage average value or energy value of the sampled signal in each time period.

[0091] S103: Compare the average values ​​of the sampled data in different time periods or the energies of the sampled data in different time periods with a preset first threshold or a first energy value to obtain a first comparison result.

[0092] The average value of the sampled data in different time periods or the energy of the sampled data in different time periods, that is, the voltage average value corresponding to the sampled signal in each time period or the energy value obtained by integrating the voltage. The voltage average value in each time period can be compared with a preset first threshold, or the energy value in each time period can be compared with the first energy value to obtain a first comparison result. The first comparison result can be whether the voltage average value or energy value in each time period is qualified. In this embodiment, when the voltage average value in each time period is greater than the preset first threshold or the energy value in each time period is greater than the first energy value, it is qualified.

[0093] S104, calculating the average value or energy value of the continuous sampling data existing within the preset sampling time, and comparing the average value or energy value of the continuous sampling data with the preset second threshold or second energy value respectively, to obtain a second comparison result; the peak value of the continuous sampling data is greater than the preset second threshold, and the continuous duration is greater than the duration threshold.

[0094] When there is a continuous sampling signal within the preset sampling time period T, and the peak value of the continuous sampling signal is greater than the preset second threshold value, and the continuous duration is greater than the duration threshold value, the average value or energy value of the continuous sampling data is calculated to obtain the voltage average value of the continuous signal or the energy value obtained by integrating the voltage, and the voltage average value of the continuous sampling data is compared with the preset second threshold value or the energy value obtained by integrating the voltage with the second energy value to obtain a second comparison result. The second comparison result can be whether the voltage average value or energy value of the continuous sampling signal is qualified. In this embodiment, when the voltage average value of the continuous sampling signal is greater than the preset second threshold value or the energy value of the continuous sampling signal is greater than the second energy value, it indicates that it is qualified. In this embodiment, there is no zero value point in the continuous sampling signal.

[0095] S105. Based on the first comparison result and the second comparison result, determine whether the electrical ignition signal is qualified.

[0096] In this embodiment, corresponding determination rules can be set according to the first comparison result and the second comparison result. For example, when both the first comparison result and the second comparison result are qualified, it means that the electric ignition signal is qualified; when only one of the first comparison result and the second comparison result is qualified, it means that the electric ignition signal is unqualified, or unstable and needs maintenance; when both the first comparison result and the second comparison result are unqualified, it means that the electric ignition signal is unqualified.

[0097] In a specific implementation, the "qualified" voltage U0 volt and the "qualified" energy value P0 of the electric firing signal can be determined according to the minimum requirements of the ammunition for the electric firing signal; the sampling time T milliseconds can be determined according to the characteristics of the electric firing signal. The data of the electric firing signal sampled for T milliseconds is processed as follows:

[0098] First, calculate the voltage average value U1 or energy value P1 of the sampling data before T / 5 time. When U1 is greater than the "qualified" voltage U0 or the energy value P1 is greater than the "qualified" energy value P0, it is judged that U1 or P1 is qualified, otherwise U1 or P1 is unqualified;

[0099] At the same time, the voltage average value U2 or energy value P2 of the last T / 5 time sampling data is calculated. When U2 is greater than the "qualified" voltage U0 or the energy value P2 is greater than the "qualified" energy value P0, U2 or P2 is judged to be qualified, otherwise U2 or P2 is unqualified;

[0100] Calculate the voltage average value U3 or energy value P3 of the sampling data at time T. When U3 is greater than the "qualified" voltage U0 or the energy value P3 is greater than the "qualified" energy value P0, it is judged that U3 or P3 is qualified, otherwise U3 or P3 is unqualified;

[0101] Secondly, when there is a continuous sampling signal with a peak voltage greater than U3 and the duration of the continuous sampling signal is not less than 3ms, calculate the voltage average value U4 or energy value P4 of the continuous sampling signal. When the voltage average value U4 is greater than the "qualified" voltage U0 or the energy value P4 is greater than the "qualified" energy value P0, U4 or P4 is judged to be qualified, otherwise U4 or P4 is unqualified.

[0102] According to the judgment results of U1, U2, U3, U4 or P1, P2, P3, P4, the state of the electric ignition signal is judged according to the pre-set judgment rules.

[0103] Table 1 below is a determination rule based on voltage value provided by this embodiment. Among them, when U1, U2, U3 and U4 are all qualified, it means that the electric ignition function is normal; when U1 and U4 are qualified and U2 is unqualified, it means that the electric ignition function is unstable and needs maintenance and repair; when U2 and U4 are qualified and U1 is unqualified, it means that the electric ignition function is unstable and needs maintenance and repair; when U3 and U4 are unqualified, it means that the electric ignition function is faulty and needs to be eliminated.

[0104] It should be noted that the indicator lights L1 and L2 can display different colors according to the judgment results of U1, U2, U3 and U4, so that the experimenter can directly judge the current electrical ignition signal according to the status of L1 and L2.
