[0022] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-4 , this utility model provides a technical solution:

[0024] A terminal for identifying and monitoring safety information of an urban low-altitude electromagnetic environment includes a signal collection module 1 and a signal analysis terminal 2. The signal collection module 1 uses a drone, and the signal collection module 1 includes a drone control module 10, a receiving antenna 11, a signal preprocessing module 12, a signal processing module 13, and a signal transmission module 14. The signal analysis terminal 2 includes a remote control module 20, a signal receiving module 21, and a signal analysis module 22. The receiving antenna 11, the signal preprocessing module 12, the signal processing module 13, and the signal transmission module 14 are electrically connected in sequence, and the signal receiving module 21 and the signal analysis module 22 are electrically connected. The receiving antenna 11 is an omnidirectional antenna for receiving signals, and the drone is used to expand the signal collection range.

[0025] In this embodiment, the drone control module 10 and the remote control module 20 cooperate with each other, and the data of the drone control module 10 and the remote control module 20 are transmitted through wireless communication. The drone control module 10 includes a processor unit, a sensor unit, a communication unit, a power supply unit and a drive unit. The processor unit is responsible for processing various sensor data, executing flight control algorithms and communicating with other modules. The sensor unit comprises an inertial measurement unit (IMU), a barometer, and a positioning unit. The IMU consists of an accelerometer, a gyroscope, and a magnetometer, and is used to measure the acceleration, angular velocity, and magnetic field direction of the UAV. The data from these sensors is fused and processed to determine the UAV's attitude. The barometer determines the UAV's altitude by measuring atmospheric pressure. The positioning unit is used to obtain the UAV's geographic location information, including longitude, latitude, and altitude. The communication unit communicates with the remote control module 20 via 4G and Wi-Fi. The power supply unit provides a stable power supply for the entire UAV control module. The power supply unit typically includes a battery, a power management chip, and a charging circuit, and may also be equipped with a power monitoring unit. The drive unit is controlled by the processor unit and includes a motor drive circuit and a servo control circuit. The motor drive circuit is used to control the UAV's motor to achieve flight control, typically using pulse width modulation technology to control the UAV's attitude and movement by adjusting the motor's speed and direction. The servo control circuit is used to control the UAV's control surfaces or other movable components, thereby changing the UAV's flight attitude or performing specific tasks.

[0026] Specifically, the signal preprocessing module 12 includes a signal amplification module 120, a signal filtering module 121 and an analog-to-digital conversion module 122. The signal amplification module 120, the signal filtering module 121 and the analog-to-digital conversion module 122 are electrically connected in sequence. Direct processing of the collected signal may cause the signal to be submerged by noise or difficult to measure accurately. The signal amplification module 120 amplifies the input signal to increase the amplitude of the signal, making it easier to be identified and processed by the subsequent processing module. The signal amplification module 120 can use an operational amplifier or a differential amplifier. The operational amplifier has the characteristics of high gain, high input impedance and low output impedance, and can greatly amplify weak signals. The differential amplifier can suppress common-mode noise and improve the signal's anti-interference ability; the signal filtering module 121 removes noise and interference from the input signal. The drone will be affected by various noises and interferences during flight. These noises will make the signal unstable and affect the accuracy of the measurement results. The signal filtering module 121 can improve the quality of the signal by filtering out noise within a specific frequency range. The analog-to-digital conversion module 122 converts the analog signal into a digital signal.

[0027] In addition, the signal transmission module 14 and the signal receiving module 21 cooperate with each other, and the data of the signal transmission module 14 and the signal receiving module 21 are transmitted through wireless communication, and the wireless communication includes 4G and WIFI.

[0028] It is worth noting that a display module 23 is also included. The display module 23 is signal-connected to the signal analysis module 22 . The display module 23 can use a common LCD display screen.

[0029] It is worth noting that a storage module 24 is also included. The storage module 24 is signal-connected to the signal analysis module 22 , and a common SD card can be used as the storage module 24 .

[0030] When the urban low-altitude electromagnetic environment safety information identification and monitoring terminal of the present invention is in use, the signal collection module 1 uses the drone to expand the signal collection range, the signal analysis terminal 2 in the signal analysis terminal 2 sends a control instruction, the drone control module 10 receives the control instruction, the drone moves according to the control instruction, the receiving antenna 11 receives the signal, and the signal passes through the signal amplification module 120, the signal filtering module 121 and the analog-to-digital conversion module 122. The signal is transmitted to the signal processing module 13, the signal processing module 13 compresses and encodes the signal, and then transmits it to the signal receiving module 21 through the signal transmission module 14. Then the signal analysis module 22 decodes and decompresses the signal, and then uses the built-in program to classify and identify the signal, extract the characteristic information of the signal, and perform a safety assessment on the identified electromagnetic signal to determine whether it poses a safety hazard to the urban low-altitude environment. Finally, the display module 23 displays the data and the storage module 24 stores the data.
