Existing natural disaster monitoring methods have some limitations, and the corresponding monitoring and detection equipment and methods of natural disasters have some defects, such as: Traditional earthquake monitoring mainly relies on seismographs, but the monitoring range of seismographs is limited, and they are not sensitive enough to monitor some small earthquakes or earthquake precursors. Landslide monitoring often uses equipment such as displacement sensors, but these devices are easily affected by environmental factors, resulting in reduced monitoring accuracy. At the same time, the installation and maintenance costs are high. In addition, existing natural disaster monitoring technologies generally have the problem of slow response time, making it difficult to issue early warning signals in a timely manner.

The accumulator 19 is located on the surface of the annular support plate 9 installed on the top of the support column 1, and the accumulator 19 supplies power to the wireless communication mobile terminal 18. The wireless communication mobile terminal 18 is connected to the millimeter-wave radar sensor 14, the signal amplifier 15, the data acquisition filter 16 and the detection and calculation server 17 through cables to form bidirectional communication.

The insulating support plate 3 located at the bottom end of the support column 1 assists the support column 1 in providing support. The storage battery 19 installed at the upper end of the annular support plate 9 is connected to the power supply of the photovoltaic panel 25. When in use, the photovoltaic panel 25 is connected to the light source. The mounting frame 24 arranged on one side of the photovoltaic panel 25 and the two spherical connecting frames 23 form a three-stage rotating connection structure. As the spherical connecting frame 23 slides with the electric drive slide 22 to adjust the light receiving position of the photovoltaic panel 25, the electric drive slide 22 slides and moves with the slide rail 21, and the power generated by the photovoltaic panel 25 enters the accumulator 19, which supplies power to the meter-wave radar sensor 14, the signal amplifier 15, the acquisition data filter 16, the detection and calculation server 17, the wireless communication mobile terminal 18 and the ground radar signal transceiver 20. When the millimeter-wave radar sensor is in use, The device 14 is linked with the signal amplifier 15 to fully detect the surrounding position in the installation area. The radar wave of the millimeter wave radar sensor 14 increases the surrounding propagation range through the signal amplifier 15. As the radar echo message received by the millimeter wave radar sensor 14 is transmitted to the acquisition data filter 16 for preprocessing, the grounded radar signal transceiver 20 is connected to the installation and maintenance area, and is connected to the wireless communication mobile terminal 18 through a data line. At the same time, the wireless communication mobile terminal 18 receives the data collected from the acquisition data filter 16 and sends the data to the control system through the local area network. The corresponding data preset threshold is set in the system so as to An alarm is sounded. During use, the millimeter-wave radar sensor is calibrated and maintained regularly to ensure its measurement accuracy and stable performance. A sound calibration and maintenance system is established to promptly discover and solve problems with the sensor. At the same time, a long-term reliability test is conducted before installation to verify the reliability and life of the hardware system. Accelerated life test, reliability growth test and other methods are used to evaluate the reliability indicators of the system, such as the mean time between failures (MTBF). Sealing materials such as sealants and sealing rings are used at the installation of the support column 1, the mounting frame 2, the positioning top plate 11 and the insulating support plate 3 to improve the reliability of the sensor. A natural disaster monitoring method based on millimeter wave radar technology comprises the following steps: S1. The millimeter-wave radar sensor 14 and the acquisition data filter 16 of the radar echo acquisition module in the installed equipment obtain various natural disaster-related millimeter-wave radar echo data; S2. Label the collected data, determine the natural disaster status corresponding to each data sample, use synthetic aperture radar image processing and InSAR technology, cooperate with the data preprocessing module to extract feature composition from the labeled data, and upload the signal to the communication warning module to monitor and warn the radar data; S3 takes the data collected by the radar echo acquisition module and puts it into the data analysis module to analyze the corresponding image and store it in conjunction with the data transmission module, and then creates a historical database and uploads it to the cloud to generate a database; S4. Regularly maintain and inspect the radar equipment, start the deep learning algorithm to select database data to enter the model training module for simulation training, and improve the accuracy of the model in acquiring and analyzing radar data; The training data in the model training module are obtained in groups from the database, and the algorithm in the model training module uses a deep learning algorithm to simulate disaster characteristics; In conjunction with the accompanying drawings Figure 1-Figure 10 As shown, when in use, the millimeter-wave radar sensor 14 and the acquisition data filter 16 of the radar echo acquisition module send millimeter-wave radar to the surrounding area, collect a large amount of millimeter-wave radar data related to various natural disasters, and store the corresponding data for model learning. These data can come from actual disaster monitoring sites, simulation experiments or radar data in historical disaster records. The calculation equation of the radar adopts the following formula:
[0030] Where Pr is the received power, Pt is the transmitted power, Gt is the transmit antenna gain, Gr is the receive antenna gain, λ is the operating wavelength of the radar, is the radar cross-sectional area of the target, R is the distance between the radar and the target, and L is the loss factor of the system; It can be seen from the formula that the radar equation includes various factors of radar detection capability such as transmission power, antenna gain, wavelength, target radar cross-sectional area, distance and system loss factor. These factors have a comprehensive impact on the radar's detection capability. Therefore, by calculating the radar equation, the radar's detection performance can be evaluated. The database needs to ensure data diversity, covering different types of natural disasters, such as landslides, floods, earthquakes, etc., different environmental conditions and different disaster degrees. After that, the data preprocessing module will label the collected data, determine the natural disaster status corresponding to each data sample, label the location, scale and development stage of the landslide, label the water level, flow rate and inundation range of the flood, etc., and the labeled data can be combined with manual labeling and automatic labeling to improve the efficiency and accuracy of labeling, such as Fig. 9 and Fig.10 As shown, the data analysis module then extracts features from the annotated data. The annotated information may include information such as the amplitude, phase, and frequency of the millimeter-wave radar echo, as well as parameters such as the distance, speed, and angle of the target object. Synthetic aperture radar image processing and InSAR technology are then used in conjunction with the data preprocessing module to extract feature structures from the annotated data. For landslides, the displacement change characteristics of the mountain surface can be extracted. For floods, the water level change and water flow velocity characteristics can be extracted. After that, the extracted features and labeled data are input into the selected algorithm model for training. By adjusting the parameters of the model, the model can learn the characteristics and laws of natural disasters. Cross-validation, regularization and other techniques are used to prevent overfitting and improve the generalization ability of the model. At the same time, the performance indicators of the algorithm, such as accuracy, recall rate, F1 value, etc., are continuously optimized. After the model calculation is completed, an independent test data set is used to evaluate the trained algorithm model. The evaluation indicators include accuracy, recall rate, precision, F1 value, etc., to measure the performance and accuracy of the algorithm model, and to verify the algorithm model to ensure that it can be used in different environmental conditions and It can work stably and reliably in disaster scenarios. When the trained algorithm model is deployed in the actual natural disaster monitoring system, as the millimeter wave radar sensor 14 and the acquisition data filter 16 obtain the corresponding data and jointly calculate with the historical database, after the obtained data reaches the warning threshold, the system immediately sends out a warning signal to ensure that relevant personnel can receive the warning information in time. At the same time, relevant departments take corresponding emergency response measures according to the warning information, organize personnel evacuation, activate emergency plans, carry out emergency rescue, etc. At the same time, through real-time monitoring of local area network data, continue to closely monitor the development of natural disasters and provide a basis for subsequent decision-making.
[0031] Working principle: When using the natural disaster monitoring instrument based on millimeter wave radar technology and its monitoring method, first transport the assembled equipment to the area to be detected, connect the millimeter wave radar sensor 14, signal amplifier 15, data acquisition filter 16, detection calculation server 17, wireless communication mobile terminal 18 and ground radar signal transceiver 20 in the equipment to the designated local area network in the area, and drive the insertion seesaw 7 to be inserted into the soil through the insertion cone column 4. As the power controller 6 turns off the magnetic force generated by the electromagnetism generator 5, the insertion seesaw 7 loses its magnetic force and is adsorbed in the layer and opens, so that the insertion seesaw 7 assists the insertion cone column 4 to maintain the overall stability of the support column 1. The insulating support plate 3 at the bottom of the support column 1 increases the grounding area. The photovoltaic panel 25 between the support column 1 and the mounting frame 2 starts to generate electricity after receiving sunlight. The electric drive slide 22 pushes the photovoltaic panel 25 to move outward as a whole, so that the photovoltaic panel 25 can increase the contact area with the external sunlight. The millimeter wave radar sensor 14 and the ground radar signal transceiver 20 cooperate to form radar data detection of the disaster status of the natural environment in the installation area. In the process of installing the equipment, the characteristics of different natural disasters are taken into consideration. The installation position should be representative and comprehensive, and can accurately monitor the area where disasters may occur. As the millimeter wave radar starts to work, it transmits millimeter wave signals and receives reflected signals. Through the analysis of the reflected signals, the distance, speed, angle and other information of the target object can be obtained, and the collected data is further pre-processed to remove noise and interference signals, improve the quality of the data, and use deep learning algorithms and models to analyze the data to extract characteristic information related to natural disasters. In landslide monitoring, the displacement trend of the mountain surface can be analyzed; In flood monitoring, water level changes and water flow speed can be analyzed; The analysis results are compared with the preset thresholds to determine whether there is a risk of natural disasters. When the risk of natural disasters is confirmed, the system immediately sends out a warning signal. As the warning signal is sent, relevant departments take corresponding emergency response measures based on the warning information, such as organizing personnel evacuation, activating emergency plans, and conducting emergency rescue. At the same time, the collected data and analysis results are stored, and a historical database is established to continue to closely monitor the development of natural disasters and provide a basis for subsequent decision-making.
