Description

Technical Field

[0001] This invention relates to the field of remote sensing monitoring technology, specifically to a remote sensing monitoring device for supervising the implementation of land and space planning. Background Technology

[0002] Remote sensing monitoring technology is a technology that uses electromagnetic wave information collected from the environment by air or satellite to monitor and identify the environmental quality of distant environmental targets. It is an advanced environmental information acquisition technology that is fast and comprehensive in acquiring large-area synchronous and dynamic environmental information, which is unmatched and unachievable by other detection methods, and is widely used in remote sensing measurement.

[0003] Currently, in traditional monitoring systems, a single radar device often struggles to simultaneously meet the requirements of monitoring range and resolution. Insufficient resolution during large-area scanning makes it impossible to detect subtle surface changes; conversely, pursuing high resolution limits the monitoring range, increasing monitoring costs and time. Furthermore, existing fixed radar devices lack flexible attitude adjustment capabilities, resulting in significantly reduced monitoring effectiveness in complex terrain and adverse weather conditions. While some existing radar systems employ multi-radar collaborative operation, each radar unit typically operates independently, lacking effective signal coordination and data processing mechanisms. When faced with sudden planning violations or geological disasters, existing devices struggle to adjust monitoring strategies promptly, failing to achieve rapid switching from wide-area scanning to precise detection. This results in an inability to simultaneously meet the needs of rapid, large-area scanning and detailed detection of key areas. Moreover, wind disturbance in complex field environments leads to image blurring and unstable monitoring data quality. Therefore, a remote sensing monitoring device for supervising the implementation of national land spatial planning is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a remote sensing monitoring device for supervising the implementation of land and space planning that can balance monitoring range and accuracy, has environmental adaptability, and can quickly switch working modes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a remote sensing monitoring device for supervising the implementation of land spatial planning, comprising: Main radar; The secondary radar is mounted on the outside of the main radar via a rotating mechanism connected to its side. The secondary radar has expandable reinforcing plate assemblies on both sides. The reinforcing plate assemblies on both sides can be deployed along their semi-circular guide rail structure, and the deployment angle is 0°-270°, so that they can be deployed or retracted relative to the secondary radar. The attitude adjustment mechanism is installed at the connection end of the secondary radar and the rotation mechanism. The attitude adjustment mechanism is used to drive the secondary radar and the reinforcement plate assembly to rotate, pitch and swing left and right. The attitude adjustment mechanism also includes a sensor group for monitoring the system attitude and the ambient wind force. The control unit is used to individually control and perform closed-loop signal processing on the main radar and the secondary radar to achieve coordinated operation of the main radar and the secondary radar. The control unit adjusts the pose of the secondary radar and the reinforcement plate assembly to counteract wind disturbance based on the sensor group data.

[0006] Preferably, the posture adjustment mechanism is driven and adjusted by one of the following structures: a six-degree-of-freedom robotic arm and a six-axis transmission structure. The motion joints of the posture adjustment mechanism integrate a high-resolution optical encoder and a torque sensor, and are driven synchronously by a servo motor.

[0007] Preferably, the reinforcing plate assembly includes a synchronous sliding support rod, which is capable of sliding along a semi-circular guide rail structure. A reinforcing arm is installed at the side end of the semi-circular guide rail structure, and a driving electromagnetic telescopic guide rod is installed at the side end of the synchronous sliding support rod. A transmission rod assembly is hinged to the side end of the driving electromagnetic telescopic guide rod.

[0008] Preferably, the front end of the synchronous sliding support rod is rotatably connected to an adjusting reinforcement plate. While the synchronous sliding support rod slides along the semi-circular guide rail structure, the telescopic movement of the driving electromagnetic telescopic guide rod can drive the adjusting reinforcement plate to operate through the transmission rod group, thereby realizing the unfolding and retraction of the reinforcement plate assembly. The adjusting reinforcement plate is configured in multiple groups, and a damping rotary joint is rotatably connected between the intervals of the two groups of adjusting reinforcement plates. The adjusting reinforcement plate is a reconfigurable metasurface, which includes an artificial electromagnetic metasurface composed of subwavelength metal resonant units arranged in a two-dimensional periodic pattern.

[0009] Preferably, the metal resonant unit of the artificial electromagnetic metasurface integrates a PIN diode or a varactor diode, and the electromagnetic response of the metal resonant unit is changed in real time by changing the bias voltage. The resonant unit of the artificial electromagnetic metasurface is fabricated on a micro-substrate that can be rotated slightly, and its physical rotation is driven by microelectromechanical systems to change the electromagnetic coupling of adjacent units.

[0010] Preferably, the surface of the secondary radar is integrated with an independent transmit / receive assembly, which includes at least a power amplifier, a low-noise amplifier, a phase shifter, and an attenuator.

[0011] Preferably, the bottom side of the secondary radar is provided with a circumferential drive structure, the output end of the circumferential drive structure is connected to a transmission arm, the side end of the transmission arm is provided with a second transmitter, the center end of the main radar is provided with a first transmitter, and the first and second transmitters of the main radar and the secondary radar share a high-stability reference clock.

[0012] Preferably, the side end of the rotating mechanism is connected to the outside of the main radar by three reinforcing connecting rods. The three reinforcing connecting rods are used to securely mount the rotating mechanism to the outside of the main radar. The side end of the three reinforcing connecting rods is connected to a flexible hinge.

[0013] Preferably, the side end of the flexible hinge is connected to a left-right swinging structure, the bottom of the left-right swinging structure is provided with a front-back pitch adjustment structure, and the bottom of the front-back pitch adjustment structure is provided with a fixed connecting seat.

[0014] Preferably, the pitch adjustment structure and the sway structure can synchronously drive the main radar to rotate, pitch and sway left and right, and the drive of the main radar and the secondary radar are controlled separately and cooperate with each other.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In this invention, seamless switching of monitoring modes is achieved through the collaboration of the main and secondary radars, along with a deployable reinforcement plate assembly. In wide-area search mode, the reinforcement plate assembly is in a retracted state, and the main and secondary radars work together to perform a large-area rapid scan. When a suspicious target is detected, the system can immediately switch to precision detection mode. At this time, the reinforcement plate assembly is deployed to its maximum extent, forming a larger effective aperture. Simultaneously, the attitude adjustment mechanism precisely adjusts the spatial attitude of the secondary radar, enabling the main and secondary radar beams to coherently superimpose in the target area, significantly improving the detection accuracy and resolution of key areas. Furthermore, the attitude adjustment mechanism can both cooperate with the main radar attitude mechanism (forward and backward pitch adjustment structure and left and right swing structure) to achieve a large-area scan during normal operation, and independently counteract wind disturbance through the high-frequency micro-motion of the six-degree-of-freedom robotic arm. When the sensor group detects the influence of environmental wind force, the control unit quickly calculates the compensation amount and drives the secondary radar and reinforcement plate assembly to perform reverse compensation movement. Simultaneously, the system can also fine-tune the beam direction of the artificial electromagnetic metasurface for electronic-level auxiliary compensation, forming a dual mechanical and electronic safety net to ensure stable and clear monitoring data even under adverse weather conditions. Furthermore, the innovative design of the reinforcement plate assembly achieves a perfect combination of mechanical expansion and electronic control. By sliding the synchronous sliding support rod along the semi-circular guide rail structure, and in conjunction with the drive electromagnetic telescopic guide rod, multiple sets of adjustable reinforcement plates are deployed via a transmission rod assembly. This not only increases radar gain by increasing the physical aperture but also achieves beamforming using the reconfigurable metasurface characteristics. The metal resonant unit of the artificial electromagnetic metasurface integrates PIN diodes or varactor diodes, allowing for real-time changes in the electromagnetic response by altering the bias voltage. Combined with microelectromechanical drive-driven physical rotation adjustment, flexible and precise control of the electromagnetic beam is achieved. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figures 1-7As shown: A remote sensing monitoring device for supervising the implementation of land spatial planning includes: a main radar 120; and a secondary radar 150, which is mounted on the outside of the main radar 120 via a rotating mechanism 130 connected to its side (the rotating mechanism 130 adopts at least one of the following rotation methods: annular magnetic levitation rotation, pre-compressed air-bearing annular bearing, and electromagnetic annular damping composite mechanism, to ensure smooth and stable rotation of the secondary radar 150 relative to the main radar 120). Expandable reinforcing plate assemblies 160 are provided on both sides of the secondary radar 150. The reinforcing plate assemblies 160 can be deployed along their semi-annular guide rail structure 161, with an deployment angle of 0°-270°, allowing for rotation relative to the secondary radar 150. The system can be expanded or retracted; a posture adjustment mechanism 170 is installed at the connection end between the secondary radar 150 and the rotation mechanism 130. The posture adjustment mechanism 170 is used to drive the secondary radar 150 and the reinforcement plate assembly 160 to rotate, pitch, and swing left and right. The posture adjustment mechanism 170 also includes a sensor group for monitoring the system attitude and environmental wind force, used to monitor environmental wind force and device attitude changes in real time; a control unit is used to individually control the main radar 120 and the secondary radar 150 and perform closed-loop signal processing to achieve the coordinated operation of the main radar 120 and the secondary radar 150. The control unit adjusts the posture of the secondary radar 150 and the reinforcement plate assembly 160 to counteract wind disturbance based on the sensor group data. The posture adjustment mechanism 170 is driven and adjusted by one of the following structures: a six-degree-of-freedom robotic arm and a six-axis transmission structure. The motion joints of the posture adjustment mechanism 170 integrate high-resolution optical encoders and torque sensors, and are simultaneously driven by servo motors to achieve precise position feedback and torque control. The reinforcing plate assembly 160 includes a synchronous sliding support rod 163, which can slide along a semi-circular guide rail structure 161. A reinforcing arm 162 is installed on the side end of the semi-circular guide rail structure 161, and a driving electromagnetic telescopic guide rod 164 is installed on the side end of the synchronous sliding support rod 163. A transmission rod assembly 165 is hinged to the side end of the driving electromagnetic telescopic guide rod 164. An adjusting reinforcing plate 166 is rotatably connected to the front end of the synchronous sliding support rod 163. While the synchronous sliding support rod 163 slides along the semi-circular guide rail structure 161, the telescopic movement of the driving electromagnetic telescopic guide rod 164 can drive the adjusting reinforcing plate 166 to work through the transmission rod assembly 165, thereby realizing the expansion and contraction of the reinforcing plate assembly 160. The adjusting reinforcing plate 166 is configured in multiple groups, and a damping rotating joint 168 is rotatably connected between two groups of adjusting reinforcing plates 166. The adjusting reinforcing plate 166 is a reconfigurable metasurface, which includes an artificial electromagnetic metasurface 167 composed of subwavelength metal resonant units arranged in a two-dimensional periodic pattern.The artificial electromagnetic metasurface 167 integrates PIN diodes or varactor diodes in its metal resonant units. The electromagnetic response of the metal resonant units is changed in real time by altering the bias voltage. The resonant units of the artificial electromagnetic metasurface 167 are fabricated on a micro-rotatable micro-substrate. Their physical rotation is driven by microelectromechanical systems (MEMS) to change the electromagnetic coupling of adjacent units, achieving flexible control of the electromagnetic beam. First, the control unit initiates the overall operation and defaults to wide-area search mode. This causes the pose adjustment mechanism 170 to drive the secondary radar 150, causing its two side reinforcement plate assemblies 160 to be in a retracted state, cooperating with the main radar for a wide-area scan (e.g., the main radar 120 scans at 20 rpm, and the secondary radar 150 scans in the retracted state). Next, the control unit controls the drive electromagnetic telescopic guide rod 164 to begin operation. The telescopic movement of the drive electromagnetic telescopic guide rod 164 is transmitted through the transmission rod assembly 165, and during this process, the synchronous sliding support rod 163 slides along the semi-circular guide rail structure 161. The reinforcing arm 162 provides additional structural support for the entire deployment process, ensuring stability. Subsequently, the transmission motion of the transmission rod assembly 165 drives the unfolding of the adjustment enhancement plate 166, which is rotatably connected to its front end. Multiple sets of adjustment enhancement plates are interconnected and their angles are adjusted through damped rotating joints 168, ultimately forming a semi-ring structure with a maximum angle of 270 degrees, which greatly increases the overall effective aperture (so that after the enhancement plate assembly 160 is unfolded, the reconfigurable metasurface 167 on it and the antenna array of the sub-radar 150 together constitute a distributed transmission system). The control unit monitors and regulates the phase of the metasurface units on each adjustment enhancement plate 166 in real time (e.g., through feedback from microwave coupling probes integrated on the edge), and uses the gradient descent-based optimization algorithm to dynamically adjust the bias voltage of the PIN diode and the physical rotation angle of the microelectromechanical system, so that the electromagnetic waves emitted by all radiating units in the target area achieve in-phase superposition (coherent superposition). This process constructs an equivalent synthetic aperture at the electronic level that is much larger than the physical size of the sub-radar body. Its principle is similar to combining the beam sharpening and resolution improvement effects of a larger aperture antenna through spatial sampling of multiple distributed units. Then, when the entire system detects suspected illegal construction or specific monitoring targets during wide-area scanning, the control unit immediately switches to precision detection mode (e.g., after a suspected target is detected, the secondary radar 150 completes attitude adjustment within 3 seconds, and the enhancement plate unfolds to the required angle within 5 seconds, enabling the selection of detection mode according to target characteristics, with the acquisition time adjustable from 1 to 10 minutes). That is, the control unit adjusts the position and orientation of the target through the attitude adjustment mechanism 170 (e.g., ...). Figure 4(As shown) The spatial pose of the secondary radar 150 is precisely adjusted. For example, the secondary radar 150 is moved to the side and front of the main radar 120, so that the beams of the main radar 120 and the secondary radar 150 coherently superimpose in the target area. At the same time, the control unit sends a command to the artificial electromagnetic metasurface 167 on the enhancement plate assembly 160. By changing the diode bias voltage or driving the microelectromechanical structure, the artificial electromagnetic metasurface 167 is made to operate in the focusing lens mode, further concentrating the radar beam energy onto the target point (that is, the control unit monitors the transmission phase of each enhancement plate 166 in real time through the microwave coupling probe integrated on the edge of the enhancement plate 166, and dynamically adjusts the bias voltage of the PIN diode by combining the gradient descent-based optimization algorithm (which is the prior art), so that the wavefront phase error formed by each enhancement plate 166 in the target area is less than λ / 20 (λ is the operating wavelength). At the same time, the phase error caused by mechanical unfolding deformation is compensated by adjusting the physical rotation angle of the resonant unit through microelectromechanical drive, ensuring the beamforming quality of the synthetic aperture). During this process, the first transmitter and second transmitter 210 of the main radar 120 and the secondary radar 150 transmit coherent signals under a shared high-stability reference clock. The echoes are received by both and sent to the control unit for joint adaptive beamforming processing, dynamically optimizing the amplitude and phase of the secondary radar 150 signal, ultimately achieving gain enhancement and beam sharpening, resulting in detection accuracy and resolution far exceeding that of traditional single radars. In harsh environments, firstly, the sensor array mounted on the attitude adjustment mechanism 170, such as an anemometer and wind speed sensor, monitors the increased wind force in real time, detecting the degree to which the wind causes slight swaying of the device. Then, the sensor data is transmitted to the control unit in real time. The processing algorithm within the control unit quickly calculates the compensation amount required to counteract this swaying. Afterward, the control unit issues commands to the attitude adjustment mechanism 170. This enables the six-degree-of-freedom robotic arm to perform high-frequency, small-amplitude compensation movements, driving the secondary radar 150 and its reinforcing plate assembly 160 to move in the opposite direction to the swaying motion. This acts as a mechanical damper, actively counteracting wind disturbances and maintaining the spatial stability of the entire detection system (i.e., real-time wind data collected by the sensor array serves as feedforward input, the compensation amount is pre-calculated using an established wind-torque transfer function model, and real-time pose data from the optical encoder serves as feedback input, undergoing fine correction via an adaptive PID algorithm. For example, a control cycle of 5ms enables disturbance suppression of over -20dB within the 0.1-5Hz wind frequency range, ensuring a system pointing error of less than 0.05° under level 8 wind conditions). Simultaneously, the control unit can also fine-tune the beam pointing of the artificial electromagnetic metasurface 167 for electronic auxiliary compensation, forming a dual mechanical and electronic safety net to ensure continuous, stable, and clear monitoring data even in adverse weather conditions. During the deployment of the reinforcing plate assembly 160, the control unit (specifically, the control unit includes a radar signal processing module, a motion control module, and a data fusion module)...The radar signal processing module adopts an FPGA-based parallel processing architecture to realize real-time correlation processing of the echo signals from the main and secondary radars; the motion control module integrates an S-curve acceleration and deceleration algorithm to ensure the smoothness of attitude adjustment; the data fusion module fuses multi-source observation data with inertial navigation information through an extended Kalman filter to generate three-dimensional monitoring data with an accuracy better than 0.1m. It monitors the phase consistency of each adjustment enhancement plate 166 in real time and ensures that the electromagnetic waves emitted by each enhancement plate unit and the secondary radar 150 are coherently superimposed in the target area by adjusting the bias voltage of the PIN diode of the artificial electromagnetic metasurface 167, thereby forming an equivalent synthetic aperture and improving the azimuth resolution of the system.

[0021] Preferred, according to Figures 1-5 As shown, the secondary radar 150 has independent transmit / receive components integrated on its surface. These components include at least a power amplifier (for amplifying the power of the transmitted signal), a low-noise amplifier (for amplifying weak echo signals while introducing extremely low self-noise), a phase shifter (for precisely controlling the phase of the signal to achieve electronic beam scanning), and an attenuator (for precisely controlling the amplitude of the signal) (such as...). Figure 1(As shown). A circular drive structure 200 (composed of a servo motor and an angle sensor) is installed on the bottom side of the secondary radar 150. The output end of the circular drive structure 200 is connected to a transmission arm 220. A second transmitter 210 is installed on the side end of the transmission arm 220 (through circular drive, the second transmitter 210 can adjust its position around the secondary radar 150 to optimize the transmission path or perform interference cancellation). A first transmitter is installed at the center end of the main radar 120. The first transmitter and the second transmitter 210 of the main radar 120 and the secondary radar 150 share a high-stability reference clock (ensuring the transmission of the entire system). The high coherence and synchronization of the signals lay a solid foundation for subsequent radar signal collaborative processing and data fusion. (The movement of the second transmitter 210 and the first transmitter of the main radar 120 form a dynamically changing interference baseline. Through the diversity of the baseline, the accuracy of the target elevation measurement can be significantly improved, and there is an opportunity to achieve super-resolution imaging. By controlling the movement of the second transmitter 210 to a specific circular position, it can coordinate with the transmission signals of the main and secondary radars to form a zero point in the direction of the interference source, thereby achieving adaptive cancellation of the interference and improving the robustness of the system in complex electromagnetic environments.) The rotating mechanism 130 is connected to the main radar 120 by three reinforcing connecting rods 180 (which, while ensuring structural rigidity, provide necessary stress buffering, effectively isolating the vibrations generated by the secondary radar 150 and its moving parts from the main radar 120, ensuring the stability of the main radar 120's detection). These three reinforcing connecting rods 180 securely mount the rotating mechanism 130 to the outside of the main radar 120. A flexible hinge 190 is connected to the side of the three reinforcing connecting rods 180 (acting as a passive buffer, capable of absorbing and attenuating minor impacts and high-frequency vibrations generated by wind disturbances or mechanism movement, further improving the overall stability of the system). A left-right swinging structure 140 is connected to the side of the flexible hinge 190. A front-to-back pitch adjustment structure 110 is installed at the bottom of the left-to-right swinging structure 140, and a fixed connecting seat 100 is installed at the bottom of the front-to-back pitch adjustment structure 110. The pitch adjustment structure 110 and the yaw structure 140 synchronously drive the main radar 120 to rotate, pitch, and yaw. The main radar 120 and the secondary radar 150 are driven independently but coordinate with each other. First, the control unit loads a preset working mode based on the specific monitoring tasks of the land use plan (e.g., monitoring urban boundary changes, supervising the progress of large-scale infrastructure construction projects, monitoring deformation in geological disaster areas). Then, the control unit issues a command, and the reinforcement plate assembly 160 begins to operate, causing the synchronous sliding support rod 163 to slide along the semi-circular guide rail structure 161. Depending on the situation, the drive electromagnetic telescopic guide rod 164 pushes multiple sets of adjustable reinforcement plates 166 to unfold via the transmission rod assembly 165, with a maximum unfolding angle of 270°, to form a larger effective aperture and improve the radar gain and resolution.During this period, the main radar 120 is driven by the front and rear pitch adjustment structure 110 and the left and right swing structure 140 (e.g.). Figure 2 As shown, the radar 150 adjusts to the preset pitch and azimuth angles and begins a large-scale, continuous scanning detection. Simultaneously, driven by the attitude adjustment mechanism 170, the secondary radar 150 adjusts its own attitude according to mission requirements, enabling high-resolution, high-precision fixed-point observation or small-area scanning of specific areas of interest. At the same time, the sensor array integrated into the attitude adjustment mechanism 170 (such as an attitude sensor and an anemometer) monitors environmental wind force and its own vibration in real time. Based on this real-time data, the control unit quickly calculates the impact of wind disturbance and immediately sends compensation commands to the attitude adjustment mechanism 170. This causes the attitude adjustment mechanism 170 to drive the secondary radar 150 and the deployed reinforcement plate assembly 160 to perform small, opposite movements via its six-degree-of-freedom robotic arm, actively counteracting the effects of wind and maintaining extreme stability in the detection direction. Furthermore, the circumferential drive structure 200 can drive the transmission arm 220 and its second transmitter 210 to the optimal position as needed, so that the transmitters of the main radar 120 and the secondary radar 150 form a specific transmission array layout to enhance signal strength or suppress interference in a specific direction. Afterwards, the echo data received by the main radar 120 and the secondary radar 150 are transmitted to the control unit in real time. Because they share the same reference clock, the control unit can perform precise coordinated signal processing and data fusion on the data from the two radars. This includes, but is not limited to, interferometry, 3D imaging, and moving target detection, thereby generating richer and more accurate monitoring information than a single radar. When the monitoring task is completed, the control unit controls the reinforcement plate assembly 160 to retract orderly to both sides of the secondary radar 150. The entire assembly returns to its original position.

[0022] The attitude adjustment mechanism 170 can cooperate with the main radar attitude mechanism (i.e., the pitch adjustment structure 110 and the yaw structure 140) to achieve a wide-range scan, and can also independently counteract wind interference through high-frequency micro-motion, achieving a perfect unity of coarse and fine adjustment. The deployment of the reinforcing plate assembly 160 not only increases the radar gain by increasing the physical aperture, but also utilizes its reconfigurable metasurface characteristics to achieve beamforming and electronic anti-interference, realizing a dual extension of mechanical and electronic capabilities. At the same time, the combination of the three reinforcing connecting rods 180 and the flexible hinge 190 provides the necessary structural rigidity support and cleverly introduces passive damping to isolate vibrations between subsystems.

[0023] The wiring diagrams of the driving electromagnetic telescopic guide rod 164 and the artificial electromagnetic metasurface 167 in this invention are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the driving electromagnetic telescopic guide rod 164 and the artificial electromagnetic metasurface 167 will not be explained in detail.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
