Description

Technical Field

[0003] In the prior art, the pyrotechnic system for scattering does usually adopt the method of ignition of electric detonator plus partition-type pyrotechnics. The electric detonator is one of the key components of the pyrotechnic subsystem for opening the cabin and scattering. It is responsible for receiving external electrical signals and converting them into sufficient energy to ignite the partition-type pyrotechnics. The partition-type pyrotechnics are another key component. They are located between the electric detonator and the scattering mechanism and play the role of transferring ignition energy. During the ignition process of the pyrotechnic subsystem for scattering, the electric detonator first receives the external electrical signal and converts it into sufficient energy. Then, this energy is transferred to the scattering mechanism through the partition-type pyrotechnics to ignite the scattering charge, thereby realizing the scattering function.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0042] See also Figure 1 , Figure 1 A schematic diagram of a high-voltage ignition device for a pyrotechnic system provided by the present invention. In a specific embodiment of the present invention, a high-voltage ignition device for a pyrotechnic system is disclosed, comprising: a safety controller 100, a plurality of shell ejection detonation assemblies 200 and a plurality of scattering detonation assemblies 300, wherein the shell ejection detonation assemblies 200 and the scattering detonation assemblies 300 are respectively connected to the safety controller 100 through cables;

[0043] Among them, the safety controller 100 is used to convert the external initial power supply voltage into a variety of power supply voltages, and generate an ignition control signal in response to the detonation control instruction;

[0044] The shell ejection detonation assembly 200 is used to be charged by a supply voltage and detonated under the control of an ignition control signal;

[0045] The scattering detonation assembly 300 is used to be charged by a supply voltage and detonated under the control of an ignition control signal.

[0046] In the above embodiment, the safety controller 100 can not only safely and efficiently convert the external initial power supply voltage (as a preferred embodiment, the initial power supply voltage in the present invention is 28V to meet the special needs of the pyrotechnic system) into a variety of different levels of power supply voltage to meet the personalized power requirements of different components, but also has a high degree of intelligent processing capabilities. Inside the safety controller 100, advanced circuit logic and protection mechanisms are integrated, which can accurately respond to the detonation control instructions from the superior control system. Once a valid detonation instruction is received, the safety controller 100 will immediately start complex algorithm processing, generate accurate ignition control signals, and quickly transmit them to each detonation component through cables.

[0047] The shell ejection detonation assembly 200 is charged by receiving the stable power supply voltage provided by the safety controller 100, ensuring sufficient energy reserves in the standby state. When the ignition control signal arrives, the ignition circuit inside the shell ejection detonation assembly 200 will respond quickly, releasing powerful energy to trigger the gunpowder or explosive in the shell ejection device, thereby realizing the shell ejection action and clearing space for subsequent pyrotechnic operations.

[0048] Similarly, the scattering detonation components 300 also work based on similar principles, but their task is to detonate at different time points or conditions to complete the scattering task in the pyrotechnic system. These components are also charged by the power supply voltage provided by the safety controller 100, and after receiving the ignition control signal, they accurately perform the detonation operation. The precise control of the scattering detonation components 300 is crucial to achieving the overall effectiveness of the pyrotechnic system. They can ensure the accurate distribution of the scattered objects to meet specific tactical or engineering requirements.

[0049] In a specific embodiment of the present invention, Figure 1 As shown, a shell ejection detonation assembly 200 and a scattering detonation assembly 300 are provided, and both are modularly designed, which is beneficial to electrical isolation and high-voltage protection, and improves the anti-interference ability of the high-voltage ignition device of the present invention.

[0050] Compared with the prior art, the high-voltage ignition device of a pyrotechnic system provided in this embodiment can accurately respond to the detonation control instruction and generate an ignition control signal by designing a safety controller 100. This precise control mechanism helps to reduce the influence of external electromagnetic field interference on the ignition process, thereby improving the accuracy and reliability of ignition. Due to the adoption of a highly integrated and modular design, the connection between each component is tighter and more reliable, further reducing the risk of ignition failure due to poor connection or component failure. With a highly integrated and modular design, the connection between each component is tighter and more reliable, further reducing the risk of ignition failure due to poor connection or component failure. The external initial power supply voltage can be converted into a variety of power supply voltages to meet the voltage requirements of different detonation components. By optimizing the circuit design and selecting high-performance electronic components, the energy loss in the conversion and transmission process is reduced, and the energy transfer efficiency is improved, so that the device can obtain a higher ignition energy output under limited power input, thereby improving the success rate and reliability of ignition.

[0051] In some embodiments of the present invention, the safety controller 100 further includes a safety control circuit board 110, and the safety control circuit board 110 includes a power management circuit 111, a safety control circuit 112, and an ignition control circuit 113; the power management circuit 111, the safety control circuit 112, and the ignition control circuit 113 are connected in sequence;

[0052] Wherein, the power management circuit 111 is used to convert the external initial power supply voltage into a variety of power supply voltages;

[0053] The insurance control circuit 112 is used to respond to the release instruction and generate a release signal according to the power supply voltage to conduct the release path;

[0054] The ignition control circuit 113 is used to generate an ignition control signal in response to the detonation control instruction.

[0055] In the above embodiment, the power management circuit 111 is responsible for finely regulating and converting the external initial power supply voltage to adapt to the power requirements of different components. It not only requires high conversion efficiency, but also ensures voltage stability to avoid affecting the normal operation of subsequent circuits due to voltage fluctuations. The power management circuit 111 can intelligently identify the voltage level of the external power supply, and convert it into a variety of different levels of power supply voltages through the internal precision conversion circuit. These voltages are respectively supplied to the shell ejection detonation component 200, the scattering detonation component 300 and other circuit parts that need power supply, ensuring that the power supply of the entire ignition system is stable and reliable.

[0056] It should be noted that the various power supply voltages converted by the power management circuit 111 can be adjusted according to actual conditions to meet the power supply requirements of the entire high-voltage ignition device, and the present invention does not impose further restrictions on this.

[0057] The original intention of designing the insurance control circuit 112 is to enhance the safety and reliability of the entire ignition system. When the high-voltage ignition device is in standby mode, the insurance control circuit 112 will remain in a locked state to prevent accidental ignition caused by misoperation or external interference. Only when receiving the release instruction issued by the superior control system, the insurance control circuit 112 will generate a release signal according to the current power supply voltage. The signal will conduct a specific release path, so that the ignition control circuit 113 can work normally, which not only increases the safety of the ignition operation, but also avoids the risk of accidental ignition caused by circuit failure.

[0058] The ignition control circuit 113 is responsible for receiving the detonation control command from the superior control system and generating an accurate ignition control signal according to the command requirements. The ignition control signal is quickly transmitted to the shell ejection detonation assembly 200 and the scattering detonation assembly 300 through the cable to trigger their ignition mechanism, thereby realizing the ignition operation of the entire pyrotechnic system. The design of the ignition control circuit 113 fully considers the speed and accuracy of signal transmission, ensuring the precise synchronization and efficient execution of the ignition operation.

[0059] See also Figure 2 , Figure 2 A circuit diagram of an embodiment of a power management circuit 111 provided by the present invention. In some embodiments of the present invention, the power management circuit 111 further includes: a forward diode V1, a transient suppression diode V2, capacitors C1, C2, C3, C4, C5, a filter U1, and DC isolation power supplies N1 and N2;

[0060] Among them, the positive pole of the forward diode V1 is connected to the external input, and the negative pole of the forward diode V1 is connected to the first port of the filter U1; the positive pole of the transient suppression diode V2 is connected to the second port of the filter U1, and the negative pole of the transient suppression diode V2 is connected to the first port of the filter U1; the third port of the filter U1 is connected to the first port of the DC isolation power supply N1, and the fourth port of the filter U1 is connected to the second port of the DC isolation power supply N1; the two ends of the capacitor C1 are connected in parallel between the third port and the fourth port of the filter U1; the two ends of the capacitor C2 are connected in parallel between the first port and the second port of the DC isolation power supply N1; the two ends of the capacitor C3 are connected in parallel between the third port and the fourth port of the DC isolation power supply N1; the first port of the DC isolation power supply N2 is connected to the first port of the DC isolation power supply N1, and the second port of the DC isolation power supply N2 is connected to the second port of the DC isolation power supply N1; the two ends of the capacitor C4 are connected in parallel between the first port and the second port of the DC isolation power supply N2; the two ends of the capacitor C5 are connected in parallel between the third port and the fourth port of the DC isolation power supply N2.

[0061] In the above embodiment, the filter circuit is composed of V1, V2, and U1, which can effectively suppress and filter out the pulse interference signal on the power supply line. The 28V power supply signal provided by the upper level is converted into a low-voltage power supply energy inside the ignition device through the filter circuit and the DC isolation power supply N1, and then converted into a high-voltage power supply energy inside the ignition device through the DC isolation power supply N2. The high and low voltage power supply isolation in the power management circuit 111 avoids the problem of failure of sensitive devices such as microcontrollers in the low-voltage circuit caused by high-voltage coupling interference in the ignition device, thereby improving the stability of the ignition device.

[0062] See also Figure 3 , Figure 3 A schematic diagram of a framework of an embodiment of the insurance control circuit 112 and the ignition control circuit 113 provided by the present invention. In some embodiments of the present invention, the insurance control circuit 112 further includes: microcontrollers D1, D2, D3, isolators E1, E2, overload sensors T1, power switch tubes K1, K2, K3, K4, K5, K6;

[0063] Wherein, the isolator E1 is connected to the microcontroller D1, and the microcontroller D1 is respectively connected to the power switch tubes K1, K2, K4, K5 and the microcontroller D3;

[0064] The isolator E2 is connected to the microcontrollers D2 and D3 respectively, the microcontroller D2 is connected to the power switch tube K3, and the microcontroller D3 is connected to the power switch tube K6.

[0065] In the above embodiment, the insurance control circuit 112 is mainly responsible for receiving the instruction sent by the upper system, releasing one three-level electric insurance to provide primary excitation for the high-voltage converter of the shell ejection detonation assembly 200, and releasing two three-level electric insurances to provide primary excitation for the high-voltage converter of the shell ejection detonation assembly 300. The specific working logic includes the following steps:

[0066] A1: The microcontroller D1 receives the first-level release instruction through the isolator E1 circuit, controls the release of the two first-level fuses, and turns on the power switches K1 and K4;

[0067] A2: When the overload sensor T1 detects the transmission acceleration and it lasts for a certain period of time, and determines that the first-level release is completed, the microcontroller D1 controls the release of the two-way second-level insurance, and the power switches K2 and K5 are turned on;

[0068] A3: Microcontrollers D2 and D3 receive the secondary release instruction through the isolator E2 circuit, and when it is determined that the secondary release is completed, they control the release of the two-way third-level fuses, and the power switches K3 and K6 are turned on;

[0069] A4: The two electrical fuses of the ignition device are released, providing excitation signals to the primary sides of the high-voltage converters of the shell ejection detonation assembly 200 and the scattering detonation assembly 300 respectively.

[0070] In some embodiments of the present invention, the ignition control circuit 113 further includes: microcontrollers D2, D3, isolators E3, E4, E5;

[0071] Among them, the isolator E3 is connected to the microcontroller D2, and the microcontroller D2 is also connected to the isolator E4; the isolator E3 is connected to the microcontroller D3, and the microcontroller D3 is also connected to the isolator E5.

[0072] In the above embodiment, the microcontroller D2 receives the ignition command output level signal through the isolator E3 circuit, which is converted by the isolator E4, and outputs the ignition control signal to provide the first detonating component 210; the microcontroller D3 receives the ignition command through the isolator E2 circuit, delays the output level signal by 100ms, and is converted by the isolator E5, and outputs the ignition control signal to provide the second detonating component 310.

[0073] It should be noted that the microcontroller in the present invention only needs to meet the processing requirements of the above instructions, and the present invention does not impose any further restrictions on its specific model requirements.

[0074] In some embodiments of the present invention, the shell ejection detonation assembly 200 includes a first detonation assembly 210 and a first pyrotechnic product 220; the shell ejection detonation assembly 300 includes a second detonation assembly 310 and a second pyrotechnic product 320; the first detonation assembly 210 is connected to the first pyrotechnic product 220, and the second detonation assembly 310 is connected to the second pyrotechnic product 320;

[0075] The first detonating assembly 210 and the second detonating assembly 310 are used to ignite the first initiating device 220 and the second initiating device 320 according to the power supply voltage and the ignition control signal, respectively;

[0076] The first initiator 220 and the second initiator 320 are used to detonate the external shell ejection transmission assembly 400 and the scattering transmission assembly 500, respectively.

[0077] In the above embodiment, the shell ejection detonation assembly 200 and the scattering detonation assembly 300 are two relatively independent but closely related systems. Specifically, the shell ejection detonation assembly 200 is mainly composed of the first detonation assembly 210 and the first pyrotechnic 220. These two parts are closely connected through precise design and manufacturing processes to ensure that the actions can be performed quickly and accurately when instructions are received. The first detonation assembly 210 is responsible for receiving and parsing the power supply voltage and ignition control signal from the external control system. After these signals are processed, the first detonation assembly 210 will trigger the first pyrotechnic 220 in a timely manner to make it enter an activated state.

[0078] Similarly, the scattering detonation assembly 300 includes a second detonation assembly 310 and a second pyrotechnic product 320, and a stable connection relationship is established between them. The working process of the second detonation assembly 310 is similar to that of the first detonation assembly 210, that is, receiving and analyzing the external power supply voltage and ignition control signal, but the specific parameters and triggering conditions of the two can be different according to the actual application requirements. After confirming that the signal is correct, the second detonation assembly 310 will activate the second pyrotechnic product 320 to prepare for the next action.

[0079] It should be noted that although the first detonating assembly 210 and the second detonating assembly 310 have similar functions, they have different responsibilities in their respective systems. The first detonating assembly 210 is mainly responsible for igniting the first pyrotechnic 220, and then detonating the external shell ejection transmission assembly 400. This usually occurs in a scenario where a certain structure or device needs to be separated from the main body, such as the shell ejection process after a rocket launch. The second detonating assembly 310 detonates the scattering transmission assembly 500 by igniting the second pyrotechnic 320. This process is mostly used to spread materials, release loads or achieve a certain specific spatial distribution, such as the scattering of fragments after an ammunition explosion. As the key actuators in the two sets of detonating assemblies, the first pyrotechnic 220 and the second pyrotechnic 320 have high reliability and stability, and can quickly and reliably complete the detonation task under extreme conditions.

[0080] In some embodiments of the present invention, the first detonating assembly 210 includes a first boosting circuit 211 and a first detonating circuit 212; the second detonating assembly 310 includes a second boosting circuit 311 and a second detonating circuit 312; the first boosting circuit 211 and the first detonating circuit 212 are connected in sequence; the second boosting circuit 311 and the second detonating circuit 312 are connected in sequence;

[0081] The first boost circuit 211 and the second boost circuit 311 are respectively used to convert the supply voltage into a preset voltage;

[0082] The first detonation circuit 212 and the second detonation circuit 312 are used to ignite the first initiating device 220 and the second initiating device 320 according to a preset voltage, respectively.

[0083] In the above embodiment, the first detonating assembly 210 is composed of two parts: the first boost circuit 211 and the first detonating circuit 212. The first boost circuit 211 is the starting point of the entire detonation process, and it is responsible for receiving the power supply voltage. The power supply voltage may fluctuate due to differences in the environment and equipment, but the first boost circuit 211 can stably convert it into a preset working voltage suitable for the detonation operation through an internal boost mechanism. This preset voltage is carefully set according to the detonation characteristics of the first pyrotechnic product 220 and the system safety requirements, ensuring the reliability and safety of the detonation process. It can be set specifically according to actual needs, and the present invention does not impose further restrictions on this.

[0084] After receiving the stable working voltage, the first detonation circuit 212 will immediately enter the standby state. Once receiving the ignition control signal from the control system, the first detonation circuit 212 will respond quickly and ignite the first pyrotechnic product 220 by generating sufficient current and energy. After receiving sufficient energy, the first pyrotechnic product 220 will quickly undergo a chemical reaction to produce a high temperature and high pressure explosion effect, thereby detonating the external shell ejection transmission assembly 400 to complete its specific task.

[0085] Similarly, the second detonating assembly 310 also includes a second boosting circuit 311 and a second detonating circuit 312, the connection and working process between which are similar to those of the first detonating assembly 210, but serve different detonation targets. The second boosting circuit 311 is also responsible for converting the supply voltage into a preset voltage suitable for detonating the second pyrotechnic 320, which preset voltage may be different or different from that in the first detonating assembly 210, because the second pyrotechnic 320 may have different detonation characteristics and requirements.

[0086] After receiving the preset voltage and the ignition control signal, the second detonating circuit 312 will also respond quickly to ignite the second pyrotechnic product 320. The explosion effect of the second pyrotechnic product 320 is used to detonate the externally connected explosive transmission assembly 500 to achieve another specific task or effect.

[0087] It is understandable that the first boost circuit 211 and the second boost circuit 311 need to ensure conversion efficiency and stability during the voltage conversion process to avoid adverse effects on subsequent detonation circuits and pyrotechnics. At the same time, the first detonation circuit 212 and the second detonation circuit 312 also need to fully consider safety and reliability during design to ensure that the detonation task can be completed normally and accurately under extreme conditions.

[0088] The first boost circuit 211 and the second boost circuit 311 both include a high-voltage converter T1, a rectifier diode V1, a high-voltage capacitor C1, high-voltage resistors (R1, R2), and a voltage regulator (F1). In this section, the first boost circuit 211 and the second boost circuit 311 are collectively described as a boost circuit. The first initiation circuit 212 and the second initiation circuit 312 both include a driver Q1, a filter capacitor (C2, C3), a high-voltage switch K1, etc. In this section, the first initiation circuit 212 and the second initiation circuit 312 are collectively described as an initiation circuit.

[0089] See also Figure 4 , Figure 4 The present invention provides a circuit diagram of an embodiment of a boost circuit and an initiation circuit. When the boost circuit receives input signals vi1 and vi2, the low voltage electricity is converted into high voltage electricity through the high voltage converter T1. After rectification by a diode, the high voltage capacitor C1 is charged. The charging time is 90ms. After the high voltage capacitor C1 is charged, the kilovolt-level signal is converted into a few volts level signal through a voltage divider circuit composed of high voltage resistors R1 and R2. The signal is converted into a high voltage feedback signal through a voltage regulator to provide a safety control circuit 112.

[0090] When the shell ejection or scattering detonation assembly 300 receives the ignition command, the 3.3V output by the controller is increased to 12V through the drivers Q1 and Q2 respectively, which is used as the working voltage of the gate of the high-voltage switch K1. The use of filter capacitors (C2 and C3) can reliably filter out the interference signal on the detonation branch, which improves the working stability of the high-voltage switch. The high-voltage switch is closed, the discharge circuit is turned on, and a pulse current of ≥3000A is output to reliably detonate the pyrotechnics 1, pyrotechnics 2 and the subsequent explosive transmission assembly.

[0091] It should be noted that the boost circuit provided by the present invention can ultimately output 1300V high voltage electricity to provide charging energy for the high voltage capacitor in the high voltage detonation circuit, thereby avoiding the problem that the electric detonator in the prior art is generally low voltage detonation, which is easy to cause ignition failure or mis-ignition under extreme environmental conditions.

[0097] In the above embodiment, the shell of the shell ejection detonation assembly 200 and the shell of the scattering detonation assembly 300 are both made of aluminum, with a size of (φ40×50) mm, and are both hollow structures. The first detonation assembly 210 and the second detonation assembly 310 are respectively encapsulated in the two cavities. The two detonation assemblies adopt a split structure design to prevent the detonation effect generated by the shell ejection detonation assembly 200 from affecting the scattering detonation assembly 300, thereby ensuring the reliable operation of the ignition device.

[0098] See also Figure 5 , Figure 5 A schematic structural diagram of an embodiment of a cable provided by the present invention. In some embodiments of the present invention, the cable is composed of an electrical connector, a shielding layer and a cable, and is used to transmit the release signal and the ignition control signal output by the safety controller 100 to the shell ejection detonation assembly 200 and the scattering detonation assembly 300.

[0099] In the above embodiment, at least two cables are provided, one cable is used for connecting the electrical interface between the safety controller 100 and the shell ejection detonating assembly 200; the other cable is used for connecting the electrical interface between the safety controller 100 and the shell ejection detonating assembly 300, and is used for transmitting the insurance signal and the ignition control signal. The cable is easy to install and operate, and is convenient for replacing the detonating assembly.

[0100] In summary, the present invention provides a high-voltage ignition device for a pyrotechnic system. By designing a safety controller 100, the controller can accurately respond to the detonation control instruction and generate an ignition control signal. This precise control mechanism helps to reduce the impact of external electromagnetic field interference on the ignition process, thereby improving the accuracy and reliability of ignition. Due to the adoption of a highly integrated and modular design, the connection between the various components is tighter and more reliable, further reducing the risk of ignition failure due to poor connection or component failure. With a highly integrated and modular design, the connection between the various components is tighter and more reliable, further reducing the risk of ignition failure due to poor connection or component failure. The external initial power supply voltage can be converted into a variety of power supply voltages to meet the voltage requirements of different detonation components. By optimizing the circuit design and selecting high-performance electronic components, the energy loss in the conversion and transmission process is reduced, and the energy transfer efficiency is improved, so that the device can obtain a higher ignition energy output under limited power input, thereby improving the success rate and reliability of ignition.
