Description

Technical Field

[0001] This utility model relates to the field of lidar technology, specifically a Raman temperature profile lidar. Background Technology

[0002] Atmospheric temperature profiles are core parameters describing the distribution of atmospheric temperature at different altitudes, playing a crucial supporting role in numerical weather prediction assimilation, tropospheric water cycle research, and climate model optimization. Raman temperature profile lidar, which inverts temperature based on the intensity ratio of nitrogen / oxygen pure rotating Raman scattering signals, has become the mainstream technology due to its high accuracy and lack of reliance on external calibration.

[0003] Traditional Raman lidar systems have fixed design limitations. Specifically, to meet the long-term observation needs of fixed sites, they typically use high-pulse-energy lasers with a repetition rate of 10-30Hz in the hundreds of millijoules range, paired with large-aperture receiving telescopes of 400mm or larger. Furthermore, the system units are dispersed, resulting in a large size and high power consumption. They are only suitable for long-term observation at fixed sites and cannot meet the needs of mobile detection for rapid emergency deployment across the entire area.

[0004] Therefore, this invention provides a Raman temperature profile lidar to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is that traditional fixed-design Raman lidar systems cannot meet the mobile detection needs of rapid deployment in emergency situations across the entire area.

[0006] This utility model provides the following technical solution: a Raman temperature profile lidar, comprising a container housing, a radar assembly, a container environmental control assembly, and vibration damping components. The container housing is divided in any direction to form a first inner chamber and a second inner chamber. An optomechanical system for the radar assembly is fixedly installed in either the first or second inner chamber. An electronic control system for the radar assembly is installed in the first or second inner chamber, located next to the optomechanical system. The container environmental control assembly is installed in the same chamber as the optomechanical system. Vibration damping components for vibration protection of the optomechanical system for the radar assembly are fixedly installed below the base. This reduces signal loss caused by optical path alignment errors, thus ensuring the stability of the optical path during use.

[0007] As a preferred embodiment of this utility model, the modular container includes a frame and a base. The container is symmetrically divided along its vertical direction to form a first inner compartment and a second inner compartment. The base is integrally and fixedly installed at the bottom of the first inner compartment above the frame. The optomechanical system is integrally and fixedly installed on top of the base. Vibration damping components are uniformly and fixedly installed between the base and the top of the bottom of the first inner compartment above the frame. The electronic control system is integrally and fixedly installed above the second inner compartment below the frame. This design avoids optical path errors caused by assembly gaps, eliminates vibrations during transportation and use, reduces signal loss caused by optical path alignment errors, and helps ensure the stability of the optical path during use.

[0008] As a preferred embodiment of this invention, the optomechanical system includes a laser emitter, a laser emitting mirror, a telescope, a motorized adjusting mirror, a filter, and a PMT module. The laser emitter is integrally and fixedly mounted on one side of the base. A laser emitting mirror aligned with the output end of the laser emitter is integrally and fixedly mounted on the base. A motorized adjusting mirror is integrally and fixedly mounted along the optical path propagation direction of the laser emitting mirror. A telescope for optical path recovery is integrally and fixedly mounted on the base and located on the side of the laser emitter. A filter is integrally and fixedly mounted on the base and along the output end direction of the telescope. A PMT module is fixedly mounted along the output end direction of the filter. This integrated optical system eliminates the need for separate disassembly or handling, and the integrated mounting eliminates assembly gaps, which helps improve the stability and accuracy of the optical system.

[0009] As one of the preferred embodiments of this utility model, the electronic control system includes a main control chassis, a laser electronic control box, a water chiller, a cooling fan, and a radar power module. The main control chassis is fixedly installed on top of the frame base, and the laser electronic control box is integrally fixedly installed on top of the main control chassis. The water chiller is fixedly installed on top of the frame base and on the side of the main control chassis. The cooling fan is fixedly installed on the bottom side wall of the frame, and the radar power module is fixedly installed on the bottom side wall of the frame perpendicular to the cooling fan.

[0010] As one of the preferred embodiments of this utility model, the cabin environment control component includes an air conditioner, a heater, and temperature and humidity sensors. The air conditioner is fixedly installed on the side wall of the frame above the base, and the heater is fixedly installed below the air conditioner. Temperature and humidity sensors are fixedly installed in any direction around the optomechanical system. This facilitates the control of the environment in which the optical path system is located and helps ensure that the optical path system can be used in different environments without interference.

[0011] As one of the preferred embodiments of this utility model, the cabin environment control component further includes a temperature control circuit board and a linear power supply circuit board. The temperature control circuit board and the linear power supply circuit board are integrally fixedly installed on the top of the base. The temperature and humidity sensor is electrically connected to the temperature control circuit board through wires, and the linear power supply circuit board is electrically connected to other electrical components through wires.

[0012] As a preferred embodiment of this invention, vibration damping components are fixedly installed at the four corners and the center of the base. This eliminates vibrations during transportation and use, provides heat insulation, reduces signal loss caused by optical path alignment errors, and helps ensure the stability of the optical path during use.

[0013] As a preferred embodiment of this invention, thermal insulation materials are integrally and fixedly installed on both sides of the base. This prevents heat dissipation and vibration of the lower-level equipment from interfering with the upper-level optomechanical system, thereby helping to ensure the stability of the optical path.

[0014] As one of the preferred embodiments of this utility model, mobile wheels are installed at the four corners of the bottom of the frame. This enables rapid deployment via vehicle, improving usability.

[0015] The beneficial effects of this utility model are as follows: 1. This utility model eliminates the traditional multi-unit mechanical splicing interface by integrating the optomechanical system with the frame and substrate through a rigid design, thus eliminating assembly gaps at the source. Furthermore, the optomechanical system and substrate are equipped with vibration dampers, which can eliminate vibrations during transportation and use and provide heat insulation, thereby reducing signal loss caused by optical path alignment errors and helping to ensure the stability of the optical path during use.

[0016] 2. The container body of this utility model provides physical protection, and the container environment control components precisely regulate the temperature and humidity inside the container. The dual system can resist high temperature and high humidity, low temperature and power supply fluctuations, and completely avoid optical path inaccuracy caused by such factors. In addition, it can be transported as a whole by relying on the vehicle, without the need for separate disassembly or handling. After arriving at the site, it only needs to be connected to an external power source to complete the preparation for use, effectively shortening the interval time from arrival to use.

[0024] Addressing the issue that traditional fixed Raman lidar systems cannot meet the needs of rapid deployment for emergency response across all regions, such as... Figures 1 to 5 As shown, this embodiment of the present disclosure provides a Raman temperature profile lidar, including a container body 1, a radar component 2, a container environment control component 3, and a vibration damping component 4. The container body 1 is divided in any direction to form a first inner chamber 11 and a second inner chamber 12. An optomechanical system 21 of the radar component 2 is fixedly installed in the first inner chamber 11 or the second inner chamber 12. An electronic control system 22 of the radar component 2 is installed in the first inner chamber 11 or the second inner chamber 12 located in the inner chamber next to the optomechanical system 21. The container environment control component 3 is installed in the same chamber as the optomechanical system 21. A vibration damping component 4 is fixedly installed below the base 14 to provide vibration damping protection for the optomechanical system 21 of the radar component 2.

[0025] In this embodiment, the container body 1 is symmetrically divided along the vertical direction to form a first inner cabin 11 and a second inner cabin 12. In addition, it can also be symmetrically divided horizontally (left-right or front-back), or diagonally, and can even be asymmetrically divided. An integrated optical-mechanical system 21 is fixedly installed in the upper first inner cabin 11, and an integrated electrical control system 22 is fixedly installed in the lower second inner cabin 12, thus forming a layered layout. Specifically, the components responsible for laser emission, conduction, and reception are integrated and installed in the upper layer. The laser control box 222, main control chassis 221, water chiller 223, cooling fan 224, and radar power module 225, responsible for the operation control, parameter adjustment, cooling, and stable power supply of the optical-mechanical system 21, are integrated and fixedly installed above the bottom of the frame 13. This avoids interference from the heat dissipation and vibration of the lower-level equipment on the upper-level optical-mechanical system 21, which helps ensure optical path stability.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the container body 1 includes a frame 13 and a base 14. The base 14 is integrally fixedly installed on the bottom of the first inner cabin 11 above the frame 13. The optomechanical system 21 is integrally fixedly installed on the base 14. Vibration damping components 4 are uniformly fixedly installed between the base 14 and the base of the first inner cabin 11 above the frame 13. The electronic control system 22 is integrally fixedly installed on the second inner cabin 12 below the frame 13.

[0027] The cabin is constructed using sandwich panels, such as those filled with polyurethane foam, and doors, windows, and seams are sealed with sealing strips and sealant. Filters are also fixedly installed at all points of connection to the outside, providing comprehensive insulation, dustproofing, and rainproofing. The base 14 is made of aviation-grade aluminum plate, and the frame 13 is made of reinforced aluminum alloy. The frame 13 and base 14 are integrally formed to ensure structural rigidity. Furthermore, the optomechanical system 21 and the electrical control system 22 are integrated and mounted on the frame 13 and base 14, eliminating gaps throughout the entire connection chain and forming a rigid whole. This provides a stable operating environment for internal equipment and helps reduce optical path errors, improving the long-term operational stability of the system.

[0028] like Figure 1 and Figure 3As shown, the optomechanical system 21 includes a laser emitter 211, a laser emitting mirror 212, a telescope 213, a motorized adjusting mirror 214, a filter 215, and a PMT module 216. The laser emitter 211 is integrally fixedly mounted on one side above the base 14. The laser emitting mirror 212, aligned with the output end of the laser emitter 211, is integrally fixedly mounted on the base 14. The motorized adjusting mirror 214 is integrally fixedly mounted in the optical path propagation direction of the laser emitting mirror 212. The telescope 213, which recovers the optical path, is integrally fixedly mounted on the base 14 and located on one side of the laser emitter 211. The filter 215 is integrally fixedly mounted on the base 14 and along the output end direction of the telescope 213. The PMT module 216 is fixedly mounted along the output end direction of the filter 215.

[0029] The PMT module converts the scattered light signal into an electrical signal and transmits it to the main control chassis, where a Boltzmann distribution-based inversion algorithm is used to calculate the temperature. The PMT module employs an existing photomultiplier tube (PMT) to convert the weak light signal into a processable electrical signal. Any existing PMT can be used; this is a commercially available and mature product, and will not be described in detail here. The filter 215 is fixed using an existing lens mount.

[0030] like Figure 1 and 2 As shown, the electronic control system 22 includes a main control chassis 221, a laser electronic control box 222, a water chiller 223, a cooling fan 224, and a radar power module 225. The main control chassis 221 is fixedly installed on the base of the frame 13. The laser electronic control box 222 is integrally fixedly installed on the main control chassis 221. The water chiller 223 is fixedly installed on the base of the frame 13 and on the side of the main control chassis 221. The cooling fan 224 is fixedly installed on the bottom side wall of the frame 13. The radar power module 225 is fixedly installed on the bottom side wall of the frame 13 perpendicular to the cooling fan 224.

[0031] The main control chassis 221 is responsible for coordinating the operation of all components, processing detection data, and receiving external commands, such as sending laser emission commands to the laser control box 222 and sending angle fine-tuning commands to the electrically adjustable reflector 214 to ensure optical path alignment. The main control chassis 221 can be a commercially available industrial-grade embedded computer. The laser control box 222 is specifically responsible for the operation control of the laser emitter 211, specifically the optomechanical system 21, and can use an STM32H743 control board in conjunction with a high-precision laser driver chip. The water chiller 223 provides water cooling for the operating heat and can be a commercially available small industrial water chiller 223. The cooling fan 224 dissipates heat from the control system 22 and can be a commercially available industrial-grade axial fan. The radar power module 225 includes an AC power input, an AC power output, a power processing module, and a UPS (Uninterruptible Power Supply). The AC power input is connected to the AC power input interface of the UPS via a cable. The UPS load output interface is connected to other electrical equipment, and the UPS has a built-in battery pack. During operation, under normal AC power conditions, the UPS directly supplies power to the load and charges the battery in bypass mode. In the event of a AC power failure, the UPS instantly switches to battery inverter power supply to prevent equipment shutdown. After AC power is restored, it automatically switches back to bypass mode and restarts charging, achieving stable power supply and ensuring uninterrupted equipment operation during power fluctuations. Details regarding the structure, drive circuit, parameter selection, and control logic of the specific components of the electrical control system 22, which are not explicitly described, are found in existing technical documents and will not be elaborated upon here.

[0032] During the rapid emergency deployment of the Raman temperature profile lidar in this embodiment, significant differences in the deployment environment can lead to optical path inaccuracies due to component deformation and condensation in environments with high temperature and humidity (relative humidity > 85%) or low temperature (< -10℃). To address this, the cabin environment control component 3 in this embodiment includes an air conditioner 31, a heater 32, and a temperature and humidity sensor 33. The air conditioner 31 is fixedly installed on the side wall of the frame 13 above the base 14, and the heater 32 is fixedly installed below the air conditioner 31. Temperature and humidity sensors 33 are fixedly installed in any direction around the optomechanical system 21. Specifically, the heater 32 can be installed in the cabin where the electronic control system 22 is located and connected to the air conditioner 31 via a pipe, or installed close to the air conditioner 31 in the same cabin.

[0033] like Figure 3As shown, during use, the temperature and humidity sensor 33 is located near the optomechanical system 21 to monitor the ambient temperature and humidity in real time and transmit signals to the controller and main control chassis 221. After comparing the set values, if the humidity is too high, the air conditioner 31 starts the cooling and dehumidification mode to reduce the humidity. If the humidity is too low, the air conditioner 31 increases the humidity through the humidification function. At the same time, if the cabin temperature is too low, it can also work with the heater 32 to raise the temperature and ventilation and fine-tune to maintain the cabin humidity stability. In this way, the temperature and humidity inside the cabin and the radar can be controlled in real time to avoid extreme environments from affecting the performance of the equipment.

[0034] like Figure 3 As shown, the cabin environment control component 3 also includes a temperature control circuit board 34 and a linear power supply circuit board 35. The temperature control circuit board 34 and the linear power supply circuit board 35 are integrally fixedly installed on the base 14. The temperature and humidity sensor 33 is electrically connected to the temperature control circuit board 34 through wires, and the linear power supply circuit board 35 is electrically connected to other electrical components through wires.

[0035] The linear power supply circuit board 35 provides a stable voltage for all electrical components, and the temperature control circuit board 34 adjusts the heat dissipation / heat preservation status according to sensor data to ensure that the optical path components work in a constant environment.

[0036] During the rapid emergency deployment of the Raman temperature profile lidar in this embodiment, optical path misalignment can easily occur due to component misalignment or deformation caused by vibration during transportation. To address this: like Figure 1 and 4 As shown, thermal insulation bodies 15 are integrally fixedly installed on both sides of the base 14. The thermal insulation bodies 15 utilize existing thermal insulation materials with low thermal conductivity, lightweight for easy vehicle transport, vibration resistance to prevent detachment and debris, tolerance to slight moisture to adapt to cabin humidity, and no dust pollution. Examples include existing polyurethane foam, glass wool, or aerogel felt. The thermal insulation bodies 15 further prevent heat dissipation and vibration from lower-level equipment from interfering with the upper-level optomechanical system 21, thereby helping to ensure the stability of the optical path.

[0037] like Figure 1 As shown, four movable wheels 16 are installed at the bottom corners of the frame 13. The movable wheels 16 facilitate the movement and transfer of the frame 13, thereby enabling rapid deployment on a vehicle and improving its flexibility of use.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, vibration damping components 4 are fixedly installed at the four corners and the center of the bottom of the base 14.

[0039] The vibration damping component 4 is a rubber vibration damper. In addition, any other existing equipment or structure capable of vibration damping can be used, such as hydraulic or pneumatic vibration dampers or dampers. The specific selection parameters or structural principles are based on existing mature foundations and will not be elaborated on here.

[0040] The base 14 is fixedly installed at the four corners and center of the bottom, thereby eliminating optical path offset caused by transportation or on-site vibration, providing a stable operating environment for internal equipment, and improving the stability of the optical path during transportation or on-site use.

[0041] The usage process of this embodiment is as follows: The frame 13 and the mobile wheels 16 work together to move to a predetermined location for quick deployment and easy use. In use, the laser emitter 211 is activated and emits a laser. The laser emitter mirror 212 calibrates the direction, and then the electric adjustment mirror 214 finely adjusts the angle to ensure that the laser is accurately projected into the atmosphere and collected by the telescope 213. The collected laser signal is filtered by the filter 215 and the mirror base 17 to remove stray light, and then transmitted to the PMT module 216 to complete the photoelectric conversion and form an effective detection signal.

[0042] During movement and use, the vibration damping component 4 can protect the optical path system from vibration, thereby eliminating optical path deviation caused by transportation or on-site vibration, providing a stable operating environment for internal equipment, and improving the stability of the optical path during transportation or on-site use. Furthermore, during use, the base 14 can separate the optical path system and the electrical control system 22, and together with the thermal insulation body 15, prevent heat dissipation and vibration of the lower-level equipment from interfering with the upper-level optomechanical system 21, thus further ensuring the stability of the optical path.

[0043] Meanwhile, during use, the linear power circuit board 35 provides a stable voltage to all electrical components. The temperature and humidity sensor 33 is located near the optomechanical system 21 to monitor the ambient temperature and humidity in real time and transmit signals to the controller and main control chassis 221. After comparing the set values, the controller and main control chassis 221 will start the cooling and dehumidification mode to reduce the humidity if the humidity is too high. If the humidity is too low, the humidity will be increased through the humidification function of the air conditioner 31. At the same time, if the cabin temperature is too low, it can also work with the heater 32 to raise the temperature and ventilation and fine-tune to maintain the cabin humidity. This allows for real-time control of the cabin and radar temperature and humidity, avoiding extreme environments from affecting equipment performance.
