[0019] Please see Figures 1 to 5 The image shows an atmospheric fast-moving electromagnetic signal monitoring system according to the first embodiment of the present invention, including a ground station 20, an inflatable electromagnetic signal induction levitation device 10, and an electromagnetic induction component.

[0020] The inflatable electromagnetic signal induction levitation device 10 is connected to the ground station 20 via a composite transmission line (not shown). The inflatable electromagnetic signal induction levitation device 10 includes an airbag levitation device, an electromagnetic signal induction mechanism 101 disposed on one side of the airbag levitation device, and a payload chamber 103 disposed on one side of the airbag levitation device. Preferably, in this embodiment, the airbag levitation device includes an airbag body and helium filled within the airbag body. The system can float using the buoyancy provided by the airbag levitation device. The payload chamber 103 is rectangular and hollow, with circular holes in the center of each of its four walls. An electromagnetic signal processing payload 50 is placed inside the air chamber, and the electromagnetic signal processing payload 50 is connected to the orientation correction mechanism 40 through the circular holes reserved in the payload chamber 103.

[0021] Specifically, in this embodiment, the inflatable electromagnetic signal sensing levitation device 10 is rectangular in shape and can sense electromagnetic signals with frequencies of 30MHz to 3000MHz. The load chamber 103 is located on one side of the bottom of the airbag levitation device.

[0022] The electromagnetic induction component includes an electromagnetic signal processing payload 50 housed within the payload compartment 103. This payload 50 receives electromagnetic signals and converts them into optical signals, which are then transmitted to the ground station 20 via the composite transmission line. The component also includes a orientation sensing mechanism 30 located on one side of the payload 50, and orientation correction mechanisms 40 located around the payload 50. Furthermore, the component includes a photoelectric conversion module 60, which comprises a solar film located on one side of the orientation correction mechanism and an energy storage module connected to the solar film. The solar film is further distributed and installed on the upper surfaces of the long arms of the two orientation correction mechanisms 40 to collect solar energy and improve the system's endurance. The energy storage module is located inside the electromagnetic signal processing payload 50. The orientation correction mechanisms 40 provide in-flight orientation correction but do not provide upward propulsion; they can be used to assist the system's automatic descent.

[0023] Specifically, in this embodiment, the electromagnetic signal processing payload 50 can collect and process electromagnetic signals with frequencies from 30MHz to 3000MHz and convert them into optical signals, which are then transmitted to the ground station 20 via a composite signal transmission line. Four orientation correction mechanisms 40, each equipped with a photoelectric conversion mechanism, are connected to the left and right sides of the electromagnetic signal processing payload 50. The orientation sensing mechanism 30 is connected to the orientation correction mechanism 40. The photoelectric conversion mechanism enhances the system's self-sufficiency, enabling the system to operate independently of ground power. The four orientation correction mechanisms 40 can adjust the system's air attitude and assist in its descent. The composite signal transmission line integrates optical fiber for transmitting high-speed digital signals and can fix the system at specific latitudes and longitudes. In some application scenarios of this embodiment, the system can be folded and stored in a rectangular storage box. The specific steps are as follows: first, the helium gas inside the airbag levitation device is discharged; then, the electromagnetic signal processing payload 50 and the orientation correction mechanism 40 located in the bottom air cavity are removed; finally, the airbag is rolled up along its long axis.

[0024] Specifically, the aforementioned inflatable electromagnetic signal sensing levitation device 10 further includes a vertical tail 102 and a horizontal tail 102 located at one end of the long axis of the airbag levitation device. The aforementioned electromagnetic induction component includes a flexible metal wire vibrator, a metal film located on one side of the flexible metal wire vibrator, and a radio frequency (RF) feed cable connected to the flexible metal wire vibrator. One end of the RF feed cable is connected to the electromagnetic signal processing load 50. The metal film is 10 cm wide. The flexible metal wire vibrator is located on the upper and lower surfaces of the airbag and is used to collect electromagnetic signals and input the sensed electromagnetic signals to the electromagnetic signal processing load 50 via the RF feed cable. Thanks to these flexible metal wires, the radiation pattern of the inflatable electromagnetic signal sensing levitation device has strong directionality, enabling high-sensitivity sensing of aerial electromagnetic signals and effectively improving the sensitivity of electromagnetic signal reception. The vertical tail 102 is located on the upper and lower surfaces of the end of the airbag levitation device. An integrated inflatable load chamber 103 is used to store the electromagnetic signal processing load 50. The load chamber 103 is connected to the electromagnetic signal processing load 50 via a buckle to fix the electromagnetic signal processing load 50 and improve the system's safety performance.

[0025] Preferably, in this embodiment, the orientation correction mechanism includes an adjustment frame and a rotor disposed on one side of the adjustment frame, and a snap-fit ​​structure is provided between the adjustment frame and the electromagnetic signal processing load 50. Specifically, the outward protrusions of the four sidewall shells of the electromagnetic signal processing load 50 form threaded annular connecting snaps. One end of the orientation correction mechanism 40 is inserted into the annular connecting snap, and the annular threaded snap fitted on the orientation correction mechanism 40 is rotated to enable the orientation correction mechanism 40 to connect with the electromagnetic signal processing load 50.

[0026] In this embodiment, the four side walls of the electromagnetic signal processing load 50 are all connected to orientation correction mechanisms 40, and orientation sensing mechanisms 30 are installed on the orientation correction mechanisms 40 connected to the left and right sides. According to the output of the orientation sensing mechanism 30, the four orientation correction mechanisms 40 adjust their respective rotor speeds. When the rotor speeds of orientation correction mechanisms 1 and 3 increase or are activated, while the rotor speeds of orientation correction mechanisms 2 and 4 remain unchanged or are not activated, the atmospheric fast-moving electromagnetic signal monitoring system and device will rotate counterclockwise around the Z-axis, and vice versa. This enables automated orientation correction of the atmospheric fast-moving electromagnetic signal monitoring system and device, effectively improving the intelligence level of the atmospheric fast-moving electromagnetic signal monitoring system and device.

[0027] Preferably, in this embodiment, the orientation correction mechanism includes a first correction mechanism and a second correction mechanism disposed opposite to each other on both sides of the electromagnetic signal processing load 50.

The first mixer 503 is electrically connected to a local oscillator module 508, and the second mixer 505 is electrically connected to a second local oscillator module 509. The first local oscillator module 508, the second local oscillator module 509, and the signal processor 507 are all electrically connected to a clock distributor 510, a multiplexer, and a multiplexer. The local oscillator module 508 provides a local oscillator signal to the first mixer 503 (high cutoff point mixer), the second local oscillator module 509 provides a second local oscillator signal to the second mixer 505, and the clock distributor 510 provides a 204.8MHz clock signal to the local oscillator module 508, the second local oscillator module 509, and the signal processor 507. By setting the high cutoff point low noise amplifier 502, the anti-interference capability of the monitoring device can be improved to a certain extent, and the accuracy of electromagnetic signal acquisition can be improved.

[0030] Preferably, the electromagnetic signal processing load further includes a first 5G mobile communication module 511, which is electrically connected to the signal processor 507. After the signal processor 507 acquires the baseband signal, it transmits it to the first 5G mobile communication module 511 and then communicates it to the monitoring center through the first 5G mobile communication module 511 to perform subsequent related operations. It can be understood that the monitoring center can also remotely control the system by transmitting instructions to the first 5G mobile communication module 511 and then transmitting them to the signal processor 507 through the first 5G mobile communication module 511. Understandably, the electromagnetic signal processing load 50 also includes a DC-DC converter, which is electrically connected to the high cutoff point low noise amplifier 502, the first mixer 503, the first intermediate frequency gain conditioning circuit 504, the second mixer 505, the second intermediate frequency gain conditioning circuit 506, the first local oscillator module 508, the second local oscillator module 509, the clock distributor 510, the signal processor 507, and the first 5G mobile communication module 511, respectively. That is, the DC-DC converter is used to power the electromagnetic signal processing load 50.
