Description

Technical Field

[0001] This utility model relates to the technical field of meteorological monitoring radar accessories, specifically to a multi-directional turning meteorological monitoring system for aerosol lidar. Background Technology

[0002] Aerosols are dispersed systems composed of solid or liquid particles suspended in a gaseous medium, with particle sizes typically ranging from 0.002 micrometers to 100 micrometers. Aerosols have a profound impact on climate change, altering the radiation balance of the Earth-atmosphere system through direct radiative forcing (absorbing and scattering long-wave radiation from the ground and short-wave radiation from the sun), and further modulating the climate system through indirect radiative forcing (acting as cloud condensation nuclei, influencing cloud formation and development).

[0003] To better monitor the distribution characteristics of atmospheric aerosols, aerosol lidar, as an advanced ground-based vertical remote sensing meteorological observation device, is widely used. Based on the Mie scattering principle, it emits laser pulses that interact with aerosols in the atmosphere, generating backscattered light. Operators obtain atmospheric aerosol distribution information by detecting the intensity of this backscattered light. However, most traditional aerosol lidar systems typically only perform detection within a fixed vertical range, making it difficult to comprehensively cover atmospheric aerosol distribution under complex terrain conditions. When facing sudden meteorological events or tracing pollution sources, a fixed detection angle often cannot meet the requirements for rapid response. Therefore, developing a meteorological monitoring system capable of multi-directional rotation based on existing aerosol observation equipment is of great significance for improving the accuracy and efficiency of atmospheric environmental monitoring. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome the limited detection range of most existing aerosol lidar devices, which are often limited to fixed vertical detection and unable to collect three-dimensional aerosol data within a certain spatial range. This invention provides a multi-directional turning meteorological monitoring system for aerosol lidar, which is compatible with existing aerosol lidar devices and supports flexible turning of the detection elevation angle, rotational scanning of the planar azimuth, and adjustment of the overall height of the device. This enables the three-dimensional acquisition of data within the target area, significantly improving the accuracy and reliability of meteorological monitoring data.

[0005] This multi-directional turning meteorological monitoring system for aerosol lidar includes an equipment support frame, a radar driver slidably mounted on the equipment support frame, an azimuth turning mechanism for controlling the radar to change its vertical azimuth and pitch angle, and a centralized control system device. The equipment support frame is equipped with a sliding support block, and drive screws and guide rods are respectively provided on both sides of the equipment support frame. The sliding support block has threaded holes and guide holes on both sides, which are respectively threaded to the drive screws and sleeved to the guide rods. The rear side of the radar driver is pivotally connected to a bushing on the front side of the sliding support block, and an angle turning motor for driving the pivot rotation is provided on one side of the sliding support block.

[0006] Furthermore, the bottom of the radar driver is rotatably connected to a mounting plate for mounting aerosol lidar and a drive shaft for driving the mounting plate to rotate. The drive shaft is connected to the mounting plate via a synchronous belt. The bottom of the radar driver is provided with an azimuth scanning motor for driving the drive shaft to rotate. The output shaft of the azimuth scanning motor passes through the bottom surface of the radar driver and is fixedly connected to the drive shaft.

[0007] Furthermore, the bottom of the equipment support frame is equipped with a height lifting motor for driving the drive screw to rotate.

[0008] Furthermore, the angle steering motor, the azimuth scanning motor, and the height lifting motor constitute an azimuth steering mechanism.

[0009] Furthermore, the centralized control system includes a PLC programmable controller for outputting action commands to each motor of the azimuth steering mechanism, a wireless data transmission module for recording the height / angle / steering azimuth information of the radar driver in real time and sending specific signals to the remote monitoring terminal, and a UPS power supply for powering each motor of the azimuth steering mechanism, the PLC programmable controller, and the wireless data transmission module.

[0010] This invention relates to a multi-directional turning meteorological monitoring system for aerosol lidar, which overcomes the problem of limited detection range in most existing aerosol lidar devices. It is compatible with existing aerosol lidar devices and supports flexible turning of the detection elevation angle, rotational scanning of the planar azimuth, and adjustment of the overall height of the device, thereby realizing the three-dimensional acquisition of three-dimensional distribution data in the target area and significantly improving the accuracy and reliability of meteorological monitoring data.

[0020] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0021] Implementation method 1: such as Figure 1 , 2As shown, the multi-directional turning meteorological monitoring system for aerosol lidar includes an equipment support frame 1, a radar driver 2 slidably mounted on the equipment support frame 1, an azimuth turning mechanism 3 for controlling the radar to change its vertical azimuth and pitch angle, and a centralized control system device 4. The equipment support frame is used to fix and support the various components of the system; the radar driver is used to cooperate in installing the core components of lidar transmission and reception; the azimuth turning mechanism is used to control the radar to change the observation point height, observation azimuth, and turning angle; the centralized control system device is used to coordinate and manage the equipment's operation mode, data recording, and transmission functions. Among them, the equipment support frame 1 is provided with a sliding support block 13, and the equipment support frame 1 has a drive screw 11 and a guide rod 12 on both sides respectively. The sliding support block 13 has wire holes and guide holes on both sides, and is connected to the drive screw 11 and the guide rod 12 respectively through the wire holes and guide holes. The rear side of the radar driver 2 is connected to the bushing 14 on the front side of the sliding support block 13 through a pivot 24. The sliding support block 13 has an angle turning motor 31 for driving the pivot 24 to rotate on one side. In the equipment support frame, the drive screw and guide rod are located on both sides of the equipment support frame. They are connected to the right sliding support block through threaded holes and guide holes, respectively, to realize the vertical movement and fixation of the sliding support block. The front end of the sliding support block is designed as a circular sleeve for nesting the radar driver. In the radar driver, the mounting plate for mounting the aerosol lidar and the transmission shaft for driving the rotation of the mounting plate are both installed at the bottom of the radar driver. The mounting plate and the transmission shaft are connected by a synchronous belt to realize the planar azimuth rotation of the radar device. A pivot is designed on the rear side of the radar driver to connect the radar support block with the sleeve.

[0022] Implementation Method 2: In this multi-directional turning meteorological monitoring system for aerosol lidar, the bottom of the radar driver 2 is rotatably connected to a mounting plate 21 for mounting the aerosol lidar and a drive shaft 22 for driving the mounting plate 21 to rotate. The drive shaft 22 is connected to the mounting plate 23 via a synchronous belt 23. The bottom of the radar driver 2 is equipped with an azimuth scanning motor 32 for driving the drive shaft 22 to rotate. The output shaft of the azimuth scanning motor 32 passes through the bottom surface of the radar driver 2 and is fixedly connected to the drive shaft 22. The bottom of the equipment support frame 1 is equipped with a height lifting motor 33 for driving the drive screw 11 to rotate. The angle turning motor 31, the azimuth scanning motor 32, and the height lifting motor 33 constitute the azimuth turning mechanism 3. An angle steering motor is located on one side of the sliding support block, mounted between the front sleeve of the sliding support block and the rear pivot of the radar driver. It adjusts the elevation angle of the radar driver by rotating the pivot, allowing for flexible adjustment of the detection elevation angle within a limited range without altering the existing antenna conditions of the aerosol lidar. An azimuth scanning motor is mounted on the bottom of the radar driver's mounting plate. The output shaft at the top of the motor passes through the bottom surface of the radar driver and is fixedly connected to the drive shaft. Adjusting the synchronous belt allows for planar azimuth rotation of the radar driver with the mounting plate as a reference. A height lifting motor is located at the bottom of the equipment support frame, mounted on the right side of the bottom of the support frame. It drives a lead screw and a guide rod to achieve vertical height adjustment and limiting of the radar driver. The remaining structures and components are as described in Embodiment 1 and will not be repeated. This achieves the raising, lowering, and fixing of the radar driver's installation height.

[0023] Implementation Method 3: The centralized control system device 4 of the multi-directional turning meteorological monitoring system for aerosol lidar includes a PLC programmable controller 41 for outputting action commands to each motor of the directional turning mechanism 3, a wireless data transmission module 42 for recording the radar driver's height / angle / turning azimuth information in real time and sending specific signals to a remote monitoring terminal, and a UPS power supply 43 for supplying power to each motor of the directional turning mechanism 3, the PLC programmable controller 41, and the wireless data transmission module 42. The remaining structures and components are as described in Implementation Method 1 and will not be repeated.

[0024] Installation and Application: The following steps will guide you through the installation and use of the aerosol lidar product designed for multi-directional meteorological monitoring systems using aerosol lidar.

[0025] Step 1 – Radar Installation and Fixing: Install the aerosol lidar onto the mounting plate of the radar driver, ensuring a secure connection between the radar and the mounting plate. Connect the mounting plate to the drive shaft via a synchronous belt. The drive shaft is driven by an azimuth scanning motor, ensuring the radar can perform rotational scanning on the plane. Insert the pivot on the rear side of the radar driver into the bushing on the front side of the sliding support block. An angle-deflecting motor connects the pivot and the bushing, ensuring the radar driver can adjust its elevation angle via the pivot. Connect the sliding support block to the drive screw through the threaded hole, and then to the guide rod through the guide hole. The screw and guide rod are controlled by a height adjustment motor, ensuring the radar driver can move vertically.

[0026] Step 2 – System Power-On Initialization: Connect the UPS power supply to the system to power the motors of the azimuth steering mechanism (angle steering motor, azimuth scanning motor, height lifting motor) and the centralized control system devices (PLC programmable controller, wireless data transmission module). Start the PLC programmable controller to perform system initialization, ensuring that all motors and sensors are in normal working condition. Detect the status of each motor through the PLC programmable controller to ensure that the radar driver is in the preset position.

[0027] Step 3 – Programming Control and Adjustment: Using a PLC programmable controller, the detection elevation angle, planar rotation angle, and vertical height range of the radar driver are set. Different scanning modes (vertical scan, horizontal scan, and 3D scan) are set according to meteorological monitoring needs. The elevation angle of the radar driver is adjusted by rotating the pivot via an angle steering motor, allowing for flexible adjustment of the detection angle in the vertical direction to meet the atmospheric aerosol monitoring needs at different altitudes. The azimuth scanning motor drives the transmission shaft, causing the mounting plate and radar to perform planar rotational scanning, enabling monitoring of aerosol distribution in different azimuths. The height adjustment motor controls the drive screw and guide rod, adjusting the vertical movement of the sliding support block, thereby adjusting the overall height of the radar driver to meet monitoring needs at different near-surface altitudes.

[0028] Step 4 – Data Recording and Transmission: During the scanning and detection process of the radar driver, the wireless data transmission module in the centralized control system records the radar driver's altitude, elevation angle, and azimuth turning information in real time. The formatted data is then sent to the remote monitoring terminal via a wireless network for analysis by meteorological monitoring personnel. The system's scanning mode and parameters can be adjusted as needed.

[0029] Step 5 – Unattended Automation: Through the programming settings of the PLC programmable controller, the system can realize unattended automated operation. At the same time, in the unattended mode, the working status of each motor and sensor is monitored in real time. In abnormal situations (such as motor overload, sensor failure, etc.), the control system automatically stops running and sends alarm information to the remote monitoring terminal through the wireless data transmission module, prompting the staff to troubleshoot and handle the fault.

[0030] This multi-directional turning meteorological monitoring system for aerosol lidar is compatible with existing aerosol lidar equipment. It supports flexible turning of the detection elevation angle, rotational scanning of the plane azimuth, and adjustment of the overall height of the equipment, thereby realizing the three-dimensional acquisition of three-dimensional distribution data within the target area, significantly improving the accuracy and reliability of meteorological monitoring data. In addition, it can be programmed and controlled by a centralized control system to achieve unattended operation.
