Description

Technical Field

[0001] This application relates to the field of airship capsule blasting technology, and more particularly to an airship capsule blasting system and method. Background Technology

[0002] Currently, capsule detonation technology has been widely used in airship-related fields. However, traditional capsule detonation schemes have some limitations. First, traditional methods typically use a single detonation device and a simple control system, making it difficult to precisely control the detonation. Furthermore, a single detonation device carries the risk of failure and irrecoverable damage under certain extreme environments, resulting in insufficient safety. Summary of the Invention

[0003] The purpose of this application is to provide a capsule explosion system and method for airships, which can solve at least one of the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides a bladder-type bursting system for an airship, comprising: a bladder and at least two bursting devices, a controller, a differential pressure gauge, a satellite positioning module, and a communication module disposed within the bladder. The bladder includes at least two vent ports, each with a vent sealing valve. The bursting elements of the at least two bursting devices are respectively disposed on the vent sealing valves at the at least two vent ports. Each bursting device is provided with a control switch. The controller is communicatively connected to each control switch. The controller is configured to cause the bursting element to burst the vent sealing valve by controlling the control switch. The differential pressure gauge, the satellite positioning module, and the communication module are communicatively connected to the controller. During airship recovery, the controller is configured to determine whether to burst more vent sealing valves based on the control switches to burst one vent sealing valve at a time, and based on the airship's descent speed and / or descent altitude obtained in real time by the satellite positioning module, or to burst the vent sealing valves based on ground commands received by the communication module.

[0005] In this embodiment, the capsule has at least two venting ports, each equipped with a venting sealing valve. A detonation device is provided for each venting sealing valve, and each detonation device has a control switch connected to a controller. The controller is configured to detonate one venting sealing valve at a time by controlling the control switch, and to determine whether to detonate more venting sealing valves based on the real-time descent speed obtained from the satellite positioning module, or to detonate venting sealing valves based on ground commands received from the communication module. Because the capsule bursting system of this application embodiment is equipped with at least two corresponding venting ports, at least two venting sealing valves, and at least two bursting devices, compared with the traditional single bursting scheme, this application embodiment can still use other bursting devices to burst the corresponding venting sealing valve when one bursting device fails, avoiding the risk of non-recovery and improving safety. Moreover, since the controller only controls the bursting of one venting sealing valve at a time, after the previous venting sealing valve is burst, the controller can determine whether to burst more venting sealing valves based on the airship descent speed and / or airship descent altitude obtained in real time by the satellite positioning module, or burst venting sealing valves through ground commands received by the communication module. Compared with the traditional single bursting scheme, this application embodiment can achieve more precise control, which is conducive to achieving a safe and reliable capsule bursting and recovery process.

[0006] Optionally, the blasting components of at least two of the blasting devices are a blasting cord and a resistance wire, respectively.

[0007] Optionally, at least two of the blasting devices are a first blasting device, a second blasting device, a third blasting device, and a fourth blasting device, wherein the blasting element of the first blasting device and the blasting element of the second blasting device are blasting cords, and the blasting element of the third blasting device and the blasting element of the fourth blasting device are resistance wires.

[0008] Optionally, the communication module includes a main satellite communication module, a backup satellite communication module, and a radio communication module, which are respectively connected to the controller.

[0009] Optionally, the system further includes a pressure-resistant and temperature-controlled chamber, in which the controller, the communication module, and the satellite positioning module are disposed; the pressure-resistant and temperature-controlled chamber also contains a battery pack and an energy management module, the energy management module being connected between the battery pack and the controller.

[0010] Optionally, the energy management module is also connected to an external energy device located on the outside of the pressure-resistant thermostatic chamber.

[0011] Optionally, the controller includes multiple I / O interfaces and multiple UART interfaces. The controller is connected to the control switch through the I / O interfaces, and the controller is connected to the communication module, the satellite positioning module, and the differential pressure gauge through the UART interfaces.

[0012] To achieve the above objectives, this application also provides a method for detonating the capsule of an airship, based on the aforementioned airship capsule detonation system, the method comprising the following steps: The controller controls a control switch to close so that the corresponding explosive component detonates the corresponding vent sealing valve; After the control switch is closed, the controller determines whether the airship descent speed and / or airship descent altitude obtained in real time by the satellite positioning module within a set time period have reached the corresponding target value. If the airship's descent speed does not reach the target descent speed value and / or the airship's descent altitude does not reach the target descent altitude value, then the next control switch is closed to cause the corresponding explosive component to detonate the corresponding vent sealing valve.

[0013] In this embodiment, the controller closes a control switch to detonate the corresponding venting valve. After closing a control switch, the controller determines whether the airship's descent speed and / or descent altitude, acquired in real-time by a satellite positioning module within a set time period, have reached the corresponding target values. If the airship's descent speed and / or descent altitude do not reach the target values, the controller closes the next control switch to detonate the corresponding venting valve. In other words, this embodiment detonates one venting valve at a time to open the corresponding vent. After detonating the previous venting valve, the next venting valve is detonated only if the airship's descent speed and / or descent altitude do not reach the target values. This embodiment can determine whether to detonate more venting valves based on monitoring key parameters during the blasting process, achieving precise control of the blasting, improving blasting reliability, and reducing risks such as blasting damage and other safety hazards.

[0014] Optionally, the controller receives a recovery command from the ground station and enters recovery mode from monitoring mode based on the recovery command. In monitoring mode, the controller is prohibited from controlling the control switch. In recovery mode, the controller can control the control switch according to a set algorithm.

[0015] To achieve the above objectives, this application also provides a method for detonating the capsule of an airship, based on the aforementioned airship capsule detonation system, the method comprising the following steps: The controller receives ground commands and controls the first control switch to close according to the ground commands, so that the corresponding explosive component detonates the corresponding venting sealing valve. Ground operators can determine whether to detonate the other vent sealing valve by observing the airship's descent speed, descent altitude, and internal and external air pressure difference returned in real time by the controller. If the judgment result is yes, then the corresponding instruction is sent to the controller, and the controller controls the second control switch to close based on the instruction.

[0016] In this embodiment, the ground operator determines whether to detonate the next venting sealing valve by observing the airship's descent speed, descent altitude, and internal / external air pressure difference returned in real time by the controller. The next venting sealing valve is detonated only when deemed necessary. Therefore, this embodiment can determine whether to detonate more venting sealing valves based on the observation of key parameters, thereby facilitating precise control of the detonation, improving detonation reliability, and reducing risks such as damage to the airship body and other safety hazards.

[0017] Optionally, the controller receives a recovery command from the ground station and enters recovery mode from monitoring mode based on the recovery command. In monitoring mode, the controller is prohibited from controlling the control switch. In recovery mode, the controller can control the control switch according to a set algorithm.

[0024] To explain in detail the technical content, structural features, objectives and effects of this application, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] Example 1 Please see Figure 1 and Figure 2 This embodiment discloses a capsule explosion system for airships.

[0026] The capsule blasting system includes: a capsule 1 and at least two blasting devices 2, a controller 3, a differential pressure gauge 4, a satellite positioning module 5, and a communication module 6 disposed within the capsule 1. The capsule 1 includes at least two vent ports 11, each equipped with a vent sealing valve 12. The blasting components 22 of the at least two blasting devices 2 are respectively disposed on the vent sealing valves 12 at the at least two vent ports 11. Each blasting device 2 is equipped with a control switch 21. The controller 3 is communicatively connected to each control switch 21. The controller 3 is configured to blast the vent sealing valves 12 by controlling the control switches 21. The differential pressure gauge 4, satellite positioning module 5, and communication module 6 are communicatively connected to the controller 3. During airship recovery, the controller 3 is configured to blast one vent sealing valve 12 at a time by controlling the control switches 21 and determining whether to blast more vent sealing valves 12 based on the real-time airship descent speed and / or airship descent altitude obtained by the satellite positioning module 5, or to blast the vent sealing valves 12 based on ground commands received by the communication module 6.

[0027] In some embodiments, the explosive elements 22 of at least two explosive devices 2 are a blasting cord 22a and a resistance wire 22b, respectively. Under extreme conditions, if one explosive device 2 fails, the other explosive device 2 can be used to blast the corresponding venting sealing valve 12, thereby improving the reliability of recovery.

[0028] It should be noted that, Figure 1 The fact that the control switch 21 is connected to the blasting cord 22a and the resistance wire 22b only indicates that the blasting cord 22a and the resistance wire 22b can be controlled by the control switch 21.

[0029] To briefly explain, the blasting device 2, where the blasting element 22 is a blasting cord 22a, may include a detonation circuit. This circuit includes a detonating device for detonating the blasting cord 22a and a control switch 21. When the control switch 21 is closed under the control of the controller 3, the detonating device detonates the blasting cord 22a, causing it to rupture the vent sealing valve 12 and open the vent port 11. The blasting device 2, where the blasting element 22 is a resistance wire 22b, may include a heating circuit. This circuit includes a resistance wire 22b and a control switch 21. When the control switch 21 is closed under the control of the controller 3, the resistance wire 22b begins to heat. After heating to a certain degree, it can rupture the vent valve. All of the above blasting devices 2 can be implemented based on existing technology, and will not be elaborated further here.

[0030] Specifically, at least two blasting devices 2 are designated as a first blasting device, a second blasting device, a third blasting device, and a fourth blasting device, respectively. Correspondingly, the number of vent ports 11 and vent sealing valves 12 corresponds to the number of blasting devices 2. The blasting element 22 of the first blasting device and the second blasting device is a blasting cord 22a, while the blasting elements 22 of the third blasting device and the fourth blasting device are resistance wires 22b.

[0031] In some embodiments, the communication module 6 includes a primary satellite communication module 61, a backup satellite communication module 62, and a radio communication module 63, all of which are communicatively connected to the controller 3. Each of these modules communicates with the ground station via a corresponding antenna. Because the primary satellite communication module 61, the backup satellite communication module 62, and the radio communication module 63 can all communicate with the ground station, reliable communication with the ground station is effectively guaranteed.

[0032] In some embodiments, the satellite positioning module 5 includes a main satellite positioning module 51 and a backup satellite positioning module 52, which are respectively connected to the controller 3 in communication. The main satellite positioning module 51 and the backup satellite positioning module 52 communicate with the satellite through corresponding antennas.

[0033] Please combine Figures 1 to 6 In some embodiments, the capsule bursting system further includes a pressure-resistant, temperature-controlled chamber 7, within which a controller 3, a communication module 6, and a satellite positioning module 5 are housed. The pressure-resistant, temperature-controlled chamber 7 also contains a battery pack 81 and an energy management module 82, with the energy management module 82 connected between the battery pack 81 and the controller 3. By placing these modules within the pressure-resistant, temperature-controlled chamber 7, the reliability of the entire system can be ensured.

[0034] Specifically, the energy management module 82 is also connected to an external energy device 83 located outside the pressure-resistant thermostatic chamber 7.

[0035] In some implementations, the controller 3 includes multiple I / O interfaces and multiple UART interfaces. The controller 3 is connected to the control switch 21 via the I / O interfaces, and to the communication module 6, the satellite positioning module 5, and the differential pressure gauge 4 via the UART interfaces. Additionally, the controller 3 is also connected to a temperature control module 9 via an I / O interface.

[0036] In this embodiment, the capsule 1 is provided with at least two vent ports 11, and each vent port 11 is provided with a vent sealing valve 12. A blasting device 2 is provided for each vent sealing valve 12, and each blasting device 2 is provided with a control switch 21 connected to the controller 3. The controller 3 is configured to blast one vent sealing valve 12 at a time by controlling the control switch 21, and to determine whether to blast more vent sealing valves 12 based on the descent speed obtained in real time by the satellite positioning module 5, or to blast the vent sealing valves 12 by ground commands received by the communication module 6. Because the capsule 1 blasting system in this embodiment is equipped with at least two corresponding venting ports 11, at least two venting sealing valves 12, and at least two blasting devices 2, compared with the traditional single blasting scheme, this embodiment can still use other blasting devices 2 to blast the corresponding venting sealing valve 12 when one of the blasting devices 2 fails, avoiding the risk of non-recovery and improving safety. Moreover, since the controller 3 only controls the blasting of one venting sealing valve 12 at a time, after the previous venting sealing valve 12 is blasted, the controller 3 can determine whether to blast more venting sealing valves 12 based on the airship descent speed and / or airship descent altitude obtained in real time by the satellite positioning module 5, or blast the venting sealing valves 12 through the ground command received by the communication module 6. Compared with the traditional single blasting scheme, this embodiment can achieve more precise control, which is conducive to achieving a safe and reliable capsule 1 blasting and recovery process.

[0037] Example 2 Please combine Figure 1 and Figure 2 This embodiment also discloses a method for detonating the capsule of an airship, based on the aforementioned airship capsule detonation system, and the method includes the following steps: Controller 3 controls a control switch 21 to close so that the corresponding explosive component 22 detonates the corresponding venting sealing valve 12; After a control switch 21 is closed, the controller 3 determines whether the airship descent speed and / or airship descent altitude, which are obtained in real time based on the satellite positioning module 5, have reached the corresponding target values ​​within a set time period. If the airship's descent speed does not reach the target descent speed value and / or the airship's descent altitude does not reach the target descent altitude value, then control the next control switch 21 to close so that the corresponding explosive component 22 detonates the corresponding vent sealing valve 12.

[0038] It should be noted that the control sequence of control switch 21 can be preset. Of course, it can also be controlled randomly.

[0039] In the specific example, the number of vent 11, vent sealing valve 12, and blasting device 2 are all four.

[0040] When it is time to recycle, the controller 3 first controls the first control switch 21 to close so that the corresponding explosive component 22 explodes the corresponding venting sealing valve 12; After the first control switch 21 is closed, the controller 3 determines whether the airship descent speed and / or airship descent altitude obtained in real time by the satellite positioning module 5 within the first set time period have reached the corresponding target value. If the airship's descent speed does not reach the target descent speed value and / or the airship's descent altitude does not reach the target descent altitude value, then control the second control switch 21 to close so that the corresponding explosive component 22 detonates the corresponding vent sealing valve 12; After the second control switch 21 is closed, the controller 3 determines whether the airship descent speed and / or airship descent altitude obtained in real time by the satellite positioning module 5 within the second set time period have reached the corresponding target value. If the airship's descent speed does not reach the target descent speed value and / or the airship's descent altitude does not reach the target descent altitude value, then control the third control switch 21 to close so that the corresponding explosive component 22 detonates the corresponding vent sealing valve 12; After the third control switch 21 is closed, the controller 3 determines whether the airship descent speed and / or airship descent altitude obtained in real time by the satellite positioning module 5 within the third set time period have reached the corresponding target value. If the airship's descent speed does not reach the target descent speed value and / or the airship's descent altitude does not reach the target descent altitude value, then the fourth control switch 21 is closed to cause the corresponding explosive component 22 to detonate the corresponding venting sealing valve 12.

[0041] In a specific example, the next control switch 21 is closed only when the airship's descent speed has not reached the target value and the airship's descent altitude has not reached the target value.

[0042] It should be noted that the first, second, and third set durations can be set to the same or different. If the conditions for closing the control switch 21 are not met, other control switches 21 will not be closed further. Subsequently, automatic monitoring or manual observation on the ground can be used to confirm whether it is necessary to close other control switches 21 to detonate more venting sealing valves 12.

[0043] Specifically, controller 3 receives a recovery command from the ground station and switches from monitoring mode to recovery mode based on the command. In monitoring mode, controller 3 prohibits control of control switch 21. In recovery mode, controller 3 can control control switch 21 according to a set algorithm. Based on the settings of monitoring mode and recovery mode, it can be ensured that control switch 21 will not be erroneously controlled during normal monitoring missions of the airship, thus preventing accidental detonation.

[0044] In this embodiment, the controller 3 controls a control switch 21 to close, causing the corresponding explosive component 22 to detonate the corresponding vent sealing valve 12. After controlling the closure of a control switch 21, the controller 3 determines whether the airship's descent speed and / or descent altitude, obtained in real time based on the satellite positioning module 5, have reached the corresponding target values ​​within a set time period. If the airship's descent speed has not reached the target descent speed value and / or descent altitude has not reached the target descent altitude value, the controller 3 controls the closure of the next control switch 21 to detonate the corresponding explosive component 22, causing the corresponding vent sealing valve 12 to detonate. That is, in this embodiment, one vent sealing valve 12 is detonated at a time to open the corresponding vent port 11. After detonating the previous vent sealing valve 12, the controller only controls the detonation of the next vent sealing valve 12 if the airship's descent speed has not reached the target descent speed value and / or descent altitude has not reached the target descent altitude value. This embodiment can determine whether to detonate more venting sealing valves 12 based on the monitoring of key parameters during the explosion of the capsule 1, thereby achieving precise control of the explosion, improving the reliability of the explosion, and reducing the risks of damage to the capsule 1 and other safety hazards.

[0045] Example 3 Please combine Figure 1 and Figure 2 This embodiment discloses a method for detonating the capsule of an airship, based on the aforementioned airship capsule detonation system. The method includes the following steps: Controller 3 receives ground commands and controls the first control switch 21 to close according to the ground commands so that the corresponding explosive component 22 detonates the corresponding venting sealing valve 12; Ground operators can determine whether to rupture the second vent sealing valve 12 by observing the airship's descent speed, descent altitude, and internal and external air pressure difference returned in real time by controller 3. If the judgment result is yes, then the corresponding instruction is sent to controller 3, and controller 3 controls the second control switch 21 to close based on the instruction.

[0046] In the specific example, the number of vent 11, vent sealing valve 12, and blasting device 2 are all four.

[0047] Correspondingly, after the controller 3 controls the second control switch 21 to close based on the instruction, the ground operator can determine whether to detonate the third venting sealing valve 12 by observing the airship descent speed, airship descent altitude and internal and external air pressure difference returned by the controller 3 in real time. If the judgment result is yes, then the corresponding instruction is sent to controller 3, and controller 3 controls the third control switch 21 to close based on the instruction; After the controller 3 controls the third control switch 21 to close based on the instruction, the ground operator can determine whether to detonate the fourth vent sealing valve 12 by observing the real-time return of the airship's descent speed, descent altitude, and internal and external air pressure difference from the controller 3. If the judgment result is yes, then the corresponding instruction is sent to controller 3, and controller 3 controls the fourth control switch 21 to close based on the instruction.

[0048] Specifically, controller 3 receives a recovery command from the ground station and switches from monitoring mode to recovery mode based on the command. In monitoring mode, controller 3 prohibits control of control switch 21. In recovery mode, controller 3 can control control switch 21 according to a set algorithm. Based on the settings of monitoring mode and recovery mode, it can be ensured that control switch 21 will not be erroneously controlled during normal monitoring missions of the airship, thus preventing accidental detonation.

[0049] In this embodiment, the ground operator observes the airship's descent speed, descent altitude, and internal / external air pressure difference returned in real time by the controller 3 to determine whether to detonate the next vent sealing valve 12. The next vent sealing valve 12 is detonated only when deemed necessary. Therefore, this application can determine whether to detonate more vent sealing valves 12 based on the observation of key parameters, thereby facilitating precise control of the detonation, improving detonation reliability, and reducing risks such as damage to the capsule 1 and other safety hazards.

[0050] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the scope of this application shall still fall within the scope of this application.
