[0024] Pyrotechnics are widely used in the civilian field. They are small sensitive explosives filled with explosives. In the aerospace and military fields, they are mostly used for aircraft engine ignition, cabin separation, and warhead detonation.

[0025] In the prior art, the ignition device of the pyrotechnics generally adopts an electric detonator, and the activation of the electric detonator is determined by the detonation current, that is, by inputting current into the pyrotechnics detonator, the resistance bridge wire of the pyrotechnics is heated, thereby detonating the ignition explosive.

[0026] At present, before the launch of an aircraft, the pyrotechnics on the bomb are often ignited through the ground test, launch and control system. Since the detonation currents of different pyrotechnic detonators are different, the design of the ignition circuit in the ground test, launch and control system often needs to comprehensively consider factors such as the technical specifications of the pyrotechnics, the application environment, the bus voltage, the cable resistance and the current limiting resistor. This results in a high degree of customization of the ignition circuit and a lack of versatility.

[0027] The initiation method, device, electronic device and computer-readable storage medium of the pyrotechnic initiator provided in the present application are intended to solve the above technical problems of the prior art.

[0028] The following describes several exemplary embodiments to illustrate the technical solutions of the embodiments of the present application and the technical effects produced by the technical solutions of the present application. It should be noted that the following embodiments can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different embodiments will not be described repeatedly.

[0029] Figure 1a An electrical connection diagram of a ground measurement, launch and control system provided for an embodiment of the present application; as shown in the figure, the ground measurement, launch and control system includes: a ground power supply, a resistive load simulator, a ground industrial computer and three relays, namely relay 1, relay 2 and relay 3; the aircraft includes three pyrotechnic initiators, namely pyrotechnic initiator 1, pyrotechnic initiator 2 and pyrotechnic initiator 3, wherein relay 1 corresponds to pyrotechnic initiator 1, relay 2 corresponds to pyrotechnic initiator 2, and relay 3 corresponds to pyrotechnic initiator 3.

[0030] Furthermore, the ground industrial computer is connected to the ground power supply, the resistance load simulator and three relays by signal lines, and the ground industrial computer communicates with the ground voltage, the resistance load simulator and the relays through the signal lines. The ground power supply and the resistance load simulator, the resistance load simulator, the resistance load simulator and the relays, the relays and the ground cable network, and the ground cable network and the pyrotechnic detonator are connected by power timing lines, and the ground power supply provides DC power to each of the above modules.

[0031] It should be noted that in the embodiment of the present application, each pyrotechnic detonator on the aircraft can form an ignition circuit with the ground measurement and control system. Taking pyrotechnic detonator 1 as an example, the ground industrial computer, ground power supply, resistance load simulator, relay, ground cable network and pyrotechnic detonator 1 constitute ignition circuit 1.

[0032] Figure 1b An equivalent schematic diagram of an ignition circuit of an pyrotechnic initiator provided in an embodiment of the present application, as shown in the figure, the ignition circuit includes: a ground power supply, a relay, a resistive load simulator, a bridge wire resistor of the pyrotechnic initiator, and a loop resistor of the ignition circuit; wherein, the output voltage of the ground power supply is αV; the resistance value of the resistive load simulator is βΩ; the resistance value of the bridge wire resistor of the pyrotechnic initiator is γΩ; and the resistance value of the loop resistor of the ignition circuit is δΩ.

[0033] In the embodiment of the present application, after the specifications of the pyrotechnic detonator are determined, the detonating current of the pyrotechnic detonator is also determined; when the relay is closed, the ground power supply supplies power to the ignition circuit, and the current i of the ignition circuit is i=α / (β+γ+δ) (A). When the current i meets the preset current and the power supply time meets the preset time, the pyrotechnic detonator is detonated.

[0034] It should be noted that in the embodiment of the present application, the ground cable network includes missile-ground communication, ground power supply to the missile and ignition circuit of pyrotechnics on the missile. Therefore, the loop resistance value in the embodiment of the present application is equal to the sum of the resistance value of the power timing line between each device (module) in the ignition loop and the resistance value of the ground cable.

[0035] In an optional embodiment, the AF-200 aviation polytetrafluoroethylene insulated wire commonly used in the industry is used in the ignition circuit, the cross-sectional area of ​​the wire is 1mm, and the length of the ground cable network is 20m. According to the wire specification, the DC resistance of the conductor per 1km at 20°C is 19Ω, and the total wire group at the ± ends of the ignition circuit is converted to 19÷1000×20×2=0.76Ω, that is, Figure 1b In the figure, δ=0.76Ω. Similarly, the resistance value of the power timing line can be calculated using the same method.

[0036] It should be noted that in the embodiment of the present application, the resistance value of the power timing line and the ground cable network will change at different ambient temperatures, and the resistance value of the power timing line and the ground cable at each ambient temperature can be determined by referring to the manual.

[0037] The following describes the solution in the embodiment of the present application using a ground-based industrial computer as the execution entity.

[0038] Figure 2A flowchart of a method for detonating an pyrotechnic initiator provided in an embodiment of the present application; the method is applied to a ground test and control system, the system includes a ground industrial computer, a ground power supply, and an pyrotechnic initiator, wherein a resistance load simulator and a relay are arranged between the ground power supply and the pyrotechnic initiator, and the method is executed by the ground industrial computer; Figure 2 As shown, the method includes: S201. Set the resistance value of the resistance load simulator to a first resistance value that matches the detonation current of the pyrotechnic initiator; wherein the resistance load simulator includes a plurality of resistors, and the resistance load simulator sets its own resistance value by combining the plurality of resistors in series and parallel through software programming.

[0039] In the embodiment of the present application, the design of the ignition circuit of the pyrotechnic initiator usually needs to comprehensively consider factors such as the pyrotechnic technical specifications, application environment, bus voltage, cable resistance and current limiting resistor. For example, the ignition current of different pyrotechnic initiators is different, the influence of ambient temperature on the resistance of the ground cable, the change of the output voltage of the ground voltage, and the increase or decrease of equipment in the test and control system will affect the current in the ignition circuit. Therefore, according to the ignition current of the pyrotechnic initiator, the resistance value required in the ignition circuit is calculated, and then the resistance value of the bridge wire resistor of the pyrotechnic initiator and the resistance value of the loop resistor are subtracted to obtain the first resistance value.

[0040] In the embodiment of the present application, the resistance load simulator includes a plurality of precision resistors, which can be combined in series and parallel through software programming, and the resistance value of the resistance load simulator is set to a first resistance value, so that the detonation current of the pyrotechnic detonator meets the preset current.

[0041] S202, control the relay to close so that the ground power supply supplies power to the pyrotechnic detonator, and in response to the ignition current of the pyrotechnic detonator meeting the preset current and the power supply duration meeting the preset duration, detonate the pyrotechnic detonator; wherein the preset current is the current required to detonate the pyrotechnic detonator, and the preset duration is the duration required to detonate the pyrotechnic detonator.

[0042] In the embodiment of the present application, there is a signal line between the ground industrial control computer and the relay, and an instruction can be sent to the relay through the signal line to control the relay to close, so that the ground power supply can supply power to the pyrotechnic detonator. When the power-on time of the bridge wire resistor of the pyrotechnic detonator meets the preset time length, the bridge wire resistor will melt and detonate the pyrotechnic detonator.

[0043] It should be noted that the preset current and preset duration of different pyrotechnic initiators are different. The following are some examples to illustrate: Example 1: Explosive device initiator 1 has a bridge wire resistor inside. A 5A~8A DC current is passed through it and it detonates within 100ms. The resistance value of the bridge wire resistor is 0.8Ω~1.2Ω.

[0044] Example 2: Explosive device initiator 2 has an internal bridge wire resistor. When a 2A~5A DC current is passed through it, it detonates within 50ms. The resistance value of the bridge wire resistor is 0.5Ω~1Ω.

[0045] Example 3: Explosive device initiator 3 has two internal bridge wire resistors. When a DC current of 2.5A to 5A flows through each bridge wire resistor, it detonates within 200ms. The resistance value of the bridge wire resistor is 0.6Ω to 1Ω.

[0046] Therefore, for the pyrotechnic detonator 1, the preset current is any value between 5A and 8A, and the preset duration is 100ms; when the relay is closed, the detonation current of the ignition circuit meets the range of 5A to 8A, and the power supply duration lasts for 100ms, which can melt the bridge wire resistance of the pyrotechnic detonator 1 and ignite the pyrotechnic detonator 1.

[0047] It should be noted that in the embodiment of the present application, after the bridge wire resistor is blown, a short circuit may occur inside the pyrotechnic detonator, and the resistance value of the pyrotechnic detonator is 0; at this time, the total resistance value of the entire ignition circuit becomes smaller, the detonation current increases, and the module in the ignition circuit (for example: the ground industrial computer) is burned out. Therefore, after the energization time of the pyrotechnic detonator reaches the preset time, the ground industrial computer will control the relay to disconnect, thereby avoiding burning out the module in the ignition circuit due to excessive detonation current.

[0048] In the embodiment of the present application, the ground industrial computer can ensure that the pyrotechnic detonator obtains a stable detonation current during the detonation process by setting the resistance value of the resistive load simulator; by controlling the closing and opening of the relay, the duration for which the ground power supply supplies power to the pyrotechnic detonator can be accurately controlled, and the preset duration is set according to the detonation requirements of the pyrotechnic detonator, ensuring that the detonator obtains sufficient energy without overheating or other safety problems due to excessive power supply time. This precise power supply duration control helps to improve the efficiency and safety of detonation.

[0049] Based on the above embodiments, as an optional embodiment, the ground industrial control computer pre-sets the detonation current of the pyrotechnic initiator, the bridge wire resistance value of the pyrotechnic initiator, and the loop resistance value of the ignition loop where the pyrotechnic initiator is located; The first resistance value is determined by: Get the output voltage of the ground power supply; According to the output voltage and the detonation current, a second resistance value is obtained, where the second resistance value is the total resistance value of the ignition circuit where the pyrotechnic detonator is located; The first resistance value is obtained according to the result of subtracting the loop resistance value and the bridge wire resistance value from the total resistance value.

[0050] In the embodiment of the present application, for any determined pyrotechnic initiator, the ignition current, bridge wire resistance value and loop resistance value of the ignition loop of the pyrotechnic initiator can be obtained in advance and saved in the ground industrial computer. For example, the user can set the ignition current, bridge wire resistance and loop resistance value in the software interface of the ground industrial computer; or set the remote terminal to communicate with the ground industrial computer, and send the above parameter values ​​to the ground industrial computer through the remote terminal.

[0051] In the embodiment of the present application, the ground industrial computer obtains the actual output voltage of the ground power supply, and can calculate the total resistance value of the ignition circuit according to the output voltage and the required detonation current. The resistance value of the resistance load simulator that needs to be set can be obtained by subtracting the loop resistance value and the bridge wire resistance value from the total resistance value, thereby ensuring that the resistance load simulator can accurately simulate the actual resistance of the ignition circuit, thereby further ensuring the accuracy of the detonation current. The embodiment of the present application can minimize the risk of detonation failure or unpredictable results caused by resistance mismatch by accurately calculating and setting the resistance value. This method of accurately matching resistance values ​​helps to improve the overall reliability and safety of the pyrotechnic detonation system.

[0052] Based on the above embodiments, as an optional embodiment, obtaining the output voltage of the ground power supply includes: Sending a first instruction to the ground power supply, where the first instruction is used to query the output voltage of the ground power supply; A first response sent by a ground power source is received, where the first response includes an output voltage of the ground power source.

[0053] In an embodiment of the present application, after receiving the ignition command from the pyrotechnic detonator, the ground industrial computer sends a first command to the ground power supply to obtain the output voltage of the ground power supply, and calculates the ignition current in the ignition circuit based on the output voltage fed back by the ground power supply.

[0054] Optionally, the embodiment of the present application may preset the message format of the first response so that the ground industrial computer can automatically identify and process the first response sent by the ground power supply, thereby quickly acquiring the output voltage of the ground power supply.

[0055] In the embodiment of the present application, by sending the first instruction to query the output voltage of the ground power supply, the automation of voltage acquisition is achieved, the tediousness of manual operation is reduced, and the work efficiency is improved.

[0056] Based on the above embodiments, as an optional embodiment, the first resistance value is obtained according to the result of subtracting the loop resistance value and the bridge wire resistance value from the total resistance value, including: If the result is a positive number, the result is used as the first resistance value; If the result is a negative number, a second instruction is sent to the ground power supply, the second instruction includes the first voltage, and the second instruction is used to instruct the ground power supply to adjust the output voltage to the first voltage until the result is a positive number.

[0057] In the embodiment of the present application, since the resistance value of the resistive load simulator cannot be set to a negative number, when the result of subtracting the loop resistance value and the bridge wire resistance value from the total resistance value is a negative number, it is necessary to adjust the output voltage of the ground power supply; since the detonating current of the pyrotechnic detonator is predetermined, it is necessary to increase the output voltage of the ground power supply to ensure that the result of subtracting the loop resistance value and the bridge wire resistance value from the total resistance value is a positive number.

[0058] It should be noted that, in the embodiment of the present application, in addition to supplying power to the ignition circuit, the ground power supply is also used to supply power to the onboard equipment before launch, and the voltage range of the onboard equipment is 18-36V, so the ground power supply voltage is generally set to 30V. Therefore, in the first response, the output voltage of the ground power supply is usually 30V, and when the result of subtracting the loop resistance value and the bridge wire resistance value from the total resistance value is negative, the ground industrial control machine will adjust the output voltage of the ground power supply to a value higher than 30V, for example: 35V, so that the result of subtracting the loop resistance value and the bridge wire resistance value from the total resistance value is positive.

[0059] For example: the resistance value of the loop resistance of the ignition circuit is δ=4Ω, the detonation current of the pyrotechnic initiator is i=7A, the resistance value of the bridge wire resistance of the pyrotechnic initiator is γ=1Ω, and the initial output voltage value of the ground power supply is α=30V. According to the calculation formula i=α / (β+γ+δ)(A), the resistance value of the resistance load simulator is -0.7Ω, that is, the result of subtracting the loop resistance value and the bridge wire resistance value from the total resistance value is a negative number. In this case, the output voltage of the ground power supply is set to 36V, then according to the calculation formula i=α / (β+γ+δ)(A), the resistance value of the resistance load simulator is 0.14Ω, which is a positive number, so the first resistance value is 0.14Ω.

[0060] In the embodiment of the present application, when the calculation result is a negative number, a second instruction is sent to the ground power supply, and the instruction includes a specific first voltage value, so that the recalculated first resistance value is a positive number. The sending of the second instruction and the adjustment of the voltage by the ground power supply ensure that the resistance load simulator can continue to work normally while meeting the current required for the pyrotechnic initiator to detonate. This adaptability enables the resistance load simulator to maintain stable performance under different working conditions, improving the reliability and flexibility of the entire detonation system.

[0061] Based on the above embodiments, as an optional embodiment, controlling the relay to close to supply power to the pyrotechnic initiator includes: The current resistance value of the resistance load simulator is the same as the first resistance value, and a first signal is sent to the relay of the ignition circuit, where the first signal is used to indicate that the relay is closed.

[0062] In the embodiment of the present application, the ground industrial computer obtains the current resistance value of the resistance load simulator according to the received third response. If the current resistance value of the resistance load simulator is the same as the first resistance value, it means that the resistance load simulator has set its own resistance value to the first resistance value, and the detonation condition of the pyrotechnic initiator has been met. Furthermore, the ground industrial computer sends a first signal to the relay of the ignition circuit. The first signal can be a 5V switching signal. After the relay receives the first signal, its internal contacts will close quickly, so that the circuit in the ignition circuit can be turned on, thereby providing the required current for the pyrotechnic initiator to detonate.

[0063] Optionally, in an embodiment of the present application, when the current resistance value of the resistance load simulator is different from the first resistance value, the ground industrial computer re-sends a third instruction to the resistance load simulator and re-receives a third response sent by the resistance load simulator.

[0064] It should be noted that if the current resistance value of the resistance load simulator in the third response re-received by the ground industrial computer is still different from the first resistance value, a fault prompt message is generated to prompt that the resistance load simulator has a fault and the user needs to manually adjust or repair the resistance load simulator.

[0065] In the embodiment of the present application, by accurately matching the first resistance value and quickly responding to the relay control, it is possible to ensure that the ground industrial computer quickly detonates after receiving the command, thereby improving the detonation efficiency. At the same time, the precise control of the resistance load simulator and the relay helps to reduce the failure rate during the detonation process and improve the reliability of the entire detonation system.

[0067] In the embodiment of the present application, after receiving the ignition instruction of the pyrotechnic initiator, the ground industrial computer obtains the output voltage of the ground power supply, and determines the total resistance of the ignition circuit according to the preset ignition current of the pyrotechnic initiator, and obtains the first resistance value as the resistance value of the resistance load simulator according to the difference between the total resistance value and the bridge wire resistance value of the pyrotechnic initiator and the resistance value of the ignition circuit. The ground industrial computer sends a third instruction to the resistance load simulator, the third instruction includes the first resistance value, and is used to instruct the resistance load simulator to set its own resistance value to the first resistance value.

[0069] In an embodiment of the present application, after setting its own resistance value, the resistance load simulator needs to send the set resistance value to the ground industrial computer, and the ground industrial computer compares the current resistance value of the resistance load simulator with the first resistance value. If they are the same, it means that the resistance load simulator has correctly set its own resistance value and the ignition conditions of the pyrotechnic detonator are ready; if they are different, it means that the resistance load simulator has not set its own resistance value to the first resistance value. At this time, the ground industrial computer re-sends a third instruction to the resistance load simulator and receives a third response. If the current resistance value of the resistance load simulator is still different from the first resistance value, a fault prompt information is reported and manual intervention is performed.

[0070] In the embodiment of the present application, the resistance load simulator can accurately receive and parse the third instruction sent by the ground industrial computer, and extract the first resistance value therefrom; according to the extracted first resistance value, the simulator can accurately adjust its internal resistance to ensure that the actual resistance value matches the first resistance value in the instruction; at the same time, after completing the resistance value setting, the resistance load simulator can quickly send a third response to the ground industrial computer, and the third response includes the current resistance value of the simulator, which provides instant feedback to the ground industrial computer and facilitates its verification of the execution of the instruction. In summary, through precise resistance value setting and efficient communication feedback, the ground industrial computer can ensure the stability and accuracy of the resistance load during the test or simulation process, which helps to reduce the risk of the pyrotechnic detonator failing to detonate normally due to resistance value mismatch or communication failure.
