[0021] In order to enable those skilled in the art to better understand the technical solutions in the present specification, the following will clearly and completely describe the technical solutions in the embodiments of the present specification with reference to the drawings in the embodiments of the present specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.
[0022] Figure 1 This is a schematic diagram of the unit structure of the bomb control device of a fire extinguishing bomb detonation system provided by an embodiment of this specification.
[0023] Figure 2 This is a schematic diagram of the unit structure of the airborne control device of a fire extinguishing bomb detonation system provided by an embodiment of this specification.
[0024] The present utility model provides a fire extinguishing bomb detonation system, which includes an airborne control device 200 and a bomb control device 100. As shown in Figure 1 and Figure 2 , the bomb control device 100 includes a detonation module 105, and the detonation module 105 includes a physical relay or a spring piece. The airborne control device 200 includes a bomb setting signal sending module 205. The bomb control device 100 further includes a communication module 102, a detonation module 105, and a self-destruction module 103.
[0025] The bomb setting signal sending module 205 is connected to the communication module 102 through a serial cable, and a safety wire is provided between the bomb setting signal sending module 205 and the communication module 102.
[0026] Among them, when the serial cable is disconnected, the safety wire is disconnected, and the physical relay or the spring piece receives a conduction signal, the self-destruction module 103 outputs a detonation current signal to the detonation module 105.
[0027] Specifically, the airborne control device 200 serves as the control center of the system and is responsible for sending instructions and signals to the bomb control device 100. The airborne control device 200 includes a bomb setting signal sending module 205, which is connected to the communication module 102 of the bomb control device 100 through a serial cable and provides additional safety protection through a safety wire. The serial cable and the safety wire provide double protection to ensure that the system will not be accidentally triggered to detonate when the communication line fails. The serial cable and the safety wire will be disconnected from the bomb setting signal sending module 205 on the airborne control device 200 under the influence of gravity when the fire extinguishing bomb is dropped. Only when the serial cable and the safety wire are both disconnected and the detonation module 105 receives a conduction signal, the self-destruction module 103 will be activated.
[0028] The communication module 102 receives instructions and signals from the airborne control device 200 and forwards them to the detonation module 105 or the self-destruction module 103.
[0029] The detonation module 105 includes a physical relay or a spring piece, which is used to perform a detonation action when receiving a detonation signal. In addition, the detonation module 105 may also be integrated with a detonating charge or other detonation mechanisms.
[0030] When the self-destruction module 103 is under specific conditions (such as when the serial port line is disconnected, the fuse line is disconnected, and the physical relay or spring piece receives a conduction signal), the self-destruction module 103 will output a detonation current signal to the detonation module 105, triggering the self-destruction mechanism of the fire extinguishing bomb to prevent the un-detonated fire extinguishing bomb from causing harm to the ground or personnel.
[0031] Preferably, the fire extinguishing bomb detonation system described in the embodiments of this specification may further include:
[0032] A distance sensor, which is arranged in the ranging module 203 of the airborne control device 200 and is used to detect the flying distance of the aircraft from the ground.
[0033] Specifically, the distance sensor measures the height of the aircraft from the ground. The fire extinguishing bomb setting controller 204 obtains the height data of the ranging module 203, calculates the delay detonation time, determines the safe detonation height, and the bomb setting signal sending module 205 sends delay data, activation instructions, and charging instructions to the bomb control device 100 to trigger the detonation action or adjust the detonation strategy.
[0034] The bomb control device 100 obtains the height data sent by the fire extinguishing bomb setting controller 204, can obtain the free fall distance of the fire extinguishing bomb from the aircraft, and can set that when the serial port line is disconnected, the fuse line is disconnected, the physical relay or spring piece receives a conduction signal, and the fire extinguishing bomb is at a safe distance from the aircraft, the self-destruction module 103 outputs a detonation current signal to the detonation module 105, triggering the self-destruction mechanism of the fire extinguishing bomb, thereby improving the detonation accuracy and ensuring the safety of the aircraft.
[0035] Preferably, the fire extinguishing bomb detonation system described in the embodiments of this specification may further include:
[0036] An impact sensor, which is arranged inside the fire extinguishing bomb and is used to detect the impact force when the fire extinguishing bomb contacts the target and send an impact signal to the self-destruction module 103.
[0037] Specifically, the impact sensor is installed inside the fire extinguishing bomb and is used to detect the impact force when the fire extinguishing bomb touches the ground or impacts the target. When the impact force reaches the preset threshold, the impact sensor sends an impact signal to the bomb control device 100 to trigger the emergency detonation or self-destruction mechanism.
[0038] It can be set that when the serial port line is disconnected, the fuse line is disconnected, the physical relay or spring piece receives a conduction signal, the fire extinguishing bomb is at a safe distance from the aircraft, and the fire extinguishing bomb is impacted, the self-destruction module 103 outputs a detonation current signal to the detonation module 105, triggering the self-destruction mechanism of the fire extinguishing bomb, which helps to prevent the fire extinguishing bomb from accidentally exploding when it does not hit the target and can also prevent the un-detonated fire extinguishing bomb from causing harm to the ground or personnel.
[0039] Preferably, the fire-extinguishing bomb detonation system described in the embodiments of this specification may further include:
[0040] A safety pin, disposed inside the detonation module 105, for preventing the detonation module 105 from being accidentally turned on.
[0041] Specifically, the safety pin is disposed inside the detonation module 105 as a mechanical safety device. Before the fire-extinguishing bomb is launched, the safety pin is in a locked state to prevent the detonation module 105 from being accidentally triggered. When the fire-extinguishing bomb flies to a predetermined position and meets the detonation conditions, the safety pin will be unlocked or broken, allowing the detonation module 105 to receive the detonation signal and perform the detonation action.
[0042] Preferably, in the embodiments of this specification, the airborne control device 200 is disposed on the aircraft, and the bomb control device 100 is disposed at the tail end of the fire-extinguishing bomb.
[0043] Preferably, the fire-extinguishing bomb detonation system described in the embodiments of this specification may further include:
[0044] A ground control device 300, communicatively connected to the airborne control device 200, for viewing the operating state of the fire-extinguishing bomb.
[0045] Figure 3 It is a schematic diagram of the unit structure of the ground control device of a fire-extinguishing bomb detonation system provided by the embodiments of this specification.
[0046] As Figure 3 shown, the ground control device 300 includes a ground power management module 301, an interface operation module 303, and a ground communication module 303. The user can intuitively view the real-time operating state of the fire-extinguishing bomb through the operation interface. The ground control device 300 is powered by the power management and communicates with the airborne control device 200 through wireless communication.
[0047] The airborne control device 200 further includes an airborne power management module 201, an airborne communication module 202, a ranging module 203, and a fire-extinguishing bomb setting control module 204. The bomb control device 100 further includes a power management module 101 and a micro-control module 104.
[0048] Among them, the power management module 101 includes a micro toggle switch. The power on and off of the bomb control device 100 is controlled by the micro toggle switch, thereby supplying power to the bomb control device 100. The micro-control module 104 can process and execute delay data, activation instructions, and charging instructions. Through the micro-control module 104, the power management module 101 can be controlled to charge the detonation module 105 and control the activation of the detonation module 105. When the power switch of the fire-extinguishing bomb is turned to the ON position, the micro-control module 104 is powered on and starts self-checking, and checks whether the connection between the communication module 102 and the airborne control device 200 is reliable. If the connection is not reliable, an error will be prompted.
[0049] The ranging module 203 includes laser ranging or millimeter-wave ranging, and can measure the real-time distance between the current altitude of the aircraft and the ground or the fire site such as the tree crown in real time. The ranging module 203 is connected to the fire extinguishing bomb setting control module 204 through a serial port.
[0050] The fire extinguishing bomb setting control module 204 converts the acquired altitude information into a delay detonation time. Specifically, the altitude difference obtained by subtracting the preset detonation altitude value from the current altitude of the aircraft is the altitude displacement difference Δh that the fire extinguishing bomb freely falls within the delay detonation time under the action of gravity. Therefore, according to the gravitational acceleration g of the fire extinguishing bomb, the delay detonation time value is calculated.
[0051] In practical applications, the detonation altitude of the fire extinguishing bomb can also be set through the operation interface of the ground control device 300, and the set detonation altitude is sent to the on-board control device 200 through wireless communication. After receiving the detonation altitude instruction, the on-board control device 200 calculates the detonation delay time by the fire extinguishing bomb setting control module 204 and then sends it to the communication module 102 of the bomb control device 100 by the bomb setting signal sending module 205, and the micro control module 104 executes the received detonation delay time.
