Description

Technical Field

[0001] The present invention relates to the technical field of meteorological monitoring and environmental data collection, and in particular to a cruise-type temperature and humidity laser radar dynamic observation system and method. Background Art

[0002] Temperature and humidity lidar is a device that measures atmospheric temperature, humidity and aerosol distribution based on laser echo signals. Its working principle is to emit lasers of a specific wavelength through a laser, receive echo signals, and calculate the temperature and humidity distribution and aerosol concentration of the target area based on signal strength and delay time. This technology has a wide range of applications in meteorological monitoring, environmental assessment and emergency response, and is particularly suitable for high-precision and high-efficiency environmental data collection.

[0003] At present, traditional temperature and humidity lidars are usually deployed in a specific area in the form of fixed stations to obtain the temperature and humidity distribution at high altitudes through vertical observation. However, in the existing technology, in order to meet the needs of large-scale and multi-point observation, the industry usually adopts the following methods: 1. Multi-point fixed deployment solution: Expand coverage by building multiple fixed sites in the city. However, this method requires a large amount of money to be invested in equipment procurement, site construction and subsequent maintenance, which is extremely costly and lacks flexibility and cannot quickly respond to sudden demands.

[0004] 2. Mobile cabin design: Some technical solutions integrate the lidar device into a mobile cabin and conduct observation by moving it over a short distance. However, this solution has the problems of complex operation, large size, slow deployment speed, and the observation data is easily disturbed by vibration in complex road conditions, making it difficult to ensure data quality.

[0005] 3. Drone-mounted solution: In order to improve flexibility, some technical solutions try to use drones equipped with lidar for observation. However, drones have limited flight time and load capacity, and are less suitable in bad weather conditions, making it difficult to meet the needs of long-term, large-scale observations.

[0006] Based on the above solutions, in order to avoid the problems of poor data quality or insufficient coverage, the industry usually tries to solve them by improving hardware performance or optimizing deployment modes. However, these methods still have the following shortcomings. For example, in complex road conditions or harsh environments, the shock absorption effect of traditional fixed installation methods and cabin designs is limited, resulting in measurement errors caused by vibration or temperature and humidity fluctuations in the lidar; or multi-point fixed deployment requires a lot of time and cost to build sites, and it is impossible to quickly adjust the observation position under temporary needs. Or drone-mounted or traditional cabin modes cannot adapt to extreme high temperature, high humidity or low temperature conditions, resulting in reduced equipment operation stability and data reliability.

[0007] Therefore, how to achieve large-scale, high-precision, low-cost dynamic observation of temperature, humidity and aerosols, and ensure the stability of the observation data and the environmental adaptability of the system has become a technical problem to be solved by the present invention.

Obviously, the described embodiments are only part 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 creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 —2. In an embodiment of the present invention, a cruise-type temperature and humidity laser radar dynamic observation system comprises: Traveling vehicle; A temperature and humidity laser radar is arranged in the vehicle and is used to monitor the temperature, humidity and aerosol information in the environment in real time; An optical skylight is arranged on the top of the vehicle and aligned with the temperature and humidity laser radar, and is used for emitting laser beams and recovering echo signals.

[0029] As a further solution of the present invention, the vehicle-mounted temperature control system includes a temperature and humidity sensor, a variable frequency air conditioner and a controller, and the controller automatically adjusts the operating state of the variable frequency air conditioner according to the detection results of the temperature and humidity sensor.

[0032] Also, the shock absorption and / or elastic structure of the present application can be understood as prior art, for example, it can be achieved by using a sponge material with a certain hardness. The sponge produces elastic deformation when subjected to external force through the evenly distributed pore structure inside it, which can effectively absorb the impact force and achieve a buffering effect. At the same time, by selecting a sponge material with appropriate density and hardness (such as a polyurethane hard sponge with a density of 30-50 kg / m³), it can not only provide good shock absorption performance, but also maintain the positioning function of the structure to prevent the equipment from shaking randomly due to vibration. In addition, this sponge structure can be bonded and fixed to the equipment housing or bracket by high-temperature resistant glue or other industrial adhesives to achieve a stable connection, which belongs to an extended implementation method known to ordinary technicians in this field.

[0034] As a further solution of the present invention, the optical skylight transmits laser light through high-transmittance optical glass and effectively shields interference of the external environment on the optical system through a protective cover.

[0035] As a further solution of the present invention, the terminal display system generates a distribution map by combining Beidou positioning data and collected temperature and humidity data, and dynamically displays the monitoring results through GIS.

[0036] Embodiment 1: This embodiment provides a specific application scenario and usage of a cruise-type temperature and humidity lidar dynamic observation system in an urban environment to illustrate how this technical solution solves problems in the prior art and achieves significant technical effects.

[0037] In a certain city, traditional temperature and humidity monitoring mainly relies on laser radar equipment deployed at fixed sites to observe high-altitude temperature and humidity. However, due to the limited number of sites, it is impossible to cover the temperature and humidity distribution of the entire city, especially the environmental differences between the core area and the edge area of ​​the city are difficult to effectively grasp. Existing fixed sites require a lot of funds to build, and lack the ability to flexibly adjust when responding to sudden meteorological events (such as strong winds and heavy rains). To address this problem, the use of the cruise temperature and humidity laser radar dynamic observation system of the present invention can significantly improve the monitoring range, flexibility and data reliability.

[0038] In specific applications, the system is deployed in a modified mobile vehicle. An optical skylight is installed on the top of the mobile vehicle, and the interior is equipped with a temperature and humidity laser radar, a radar fixed shock-absorbing structure, an on-board temperature control system, a mobile power supply, and a terminal display system. The following is the specific usage of the system: After the system is started, the Beidou positioning system obtains the real-time location information of the vehicle and presets a dynamic observation route in combination with the city's GIS map. The vehicle travels along the preset route, and the temperature and humidity lidar emits lasers through the optical skylight and receives echo signals, obtaining real-time high-altitude temperature, humidity and aerosol distribution data along the way. The terminal display system displays the real-time collected data in the form of pseudo-color images and marks them at the corresponding locations on the map for operator monitoring.

[0039] During vehicle driving, bumpy roads may cause vibrations in the radar equipment, affecting the stability of data collection. The radar fixed shock-absorbing structure in the system absorbs road vibrations through elastic steel rings and shock-absorbing bases to ensure that the lidar always maintains stable operation. At the same time, the on-board temperature control system dynamically adjusts environmental parameters based on the real-time detection results of the internal temperature and humidity sensors to ensure that the equipment can still operate efficiently in extreme weather conditions (such as high temperatures in summer or low temperatures in winter). This combination of vibration reduction and environmental control design enables the system to obtain high-quality data under complex road conditions.

[0040] The collected temperature, humidity and aerosol data are analyzed by the data processing module and combined with the location information of the Beidou positioning system to generate a dynamic distribution map with time and space dimensions. These data can not only be displayed in real time, but also be remotely transmitted to the meteorological monitoring center through the communication module to provide a basis for decision-making for city managers. For example, during the heavy rainfall warning period, the system can quickly drive through various areas of the city to dynamically obtain the temperature and humidity gradient distribution, and provide high-precision disaster warning data support for the meteorological department.

[0041] Scenario 1: Routine urban environmental monitoring.

[0042] The system monitors along a fixed route every day, obtains temperature, humidity and aerosol data in different areas of the city, and forms a dynamic monitoring network. Compared with traditional multi-point fixed sites, the cruise system can cover a larger area with the same budget, significantly reducing monitoring costs.

[0043] Scenario 2: Emergency response to unexpected events.

[0044] In the event of a pollutant leak or extreme weather conditions, the system can be quickly deployed to the pollution source or weather abnormality area to monitor environmental changes in real time and provide accurate data support for emergency response. Traditional technologies are not competent in such scenarios due to their lack of flexibility, but this system can respond efficiently.

[0045] The vibration reduction capability of the present invention in complex road conditions significantly improves the accuracy and reliability of temperature and humidity lidar data; through the high light transmittance design and protection function of the optical skylight, the equipment can still maintain efficient operation in harsh environments such as dust and rain, reducing maintenance requirements; Beidou positioning is combined with GIS maps to achieve multi-dimensional display of data, providing a more intuitive analysis basis for urban management and weather forecasting.

[0046] Embodiment 2: This embodiment provides a mobile temperature and humidity laser radar device, which mainly includes: a mobile vehicle, a temperature and humidity laser radar, an optical skylight, a Beidou system, a temperature and humidity sensor, a mobile power supply, a radar fixed shock-absorbing structure, a communication system, a vehicle-mounted computer system, a vehicle-mounted temperature control system, and a terminal display system. The temperature and humidity mobile device is characterized in that: a radar fixed shock-absorbing structure is installed in the mobile vehicle near the cab of the vehicle, and the shock-absorbing structure is rigidly fixed to the vehicle to ensure reliable installation. The temperature and humidity laser radar is installed in the fixed shock-absorbing structure, and the elastic steel ring in the shock-absorbing structure is used to realize the anti-seismic of the whole radar. When the vehicle is moving for monitoring, the radar eliminates the bumps of the road through the shock-absorbing device to ensure the stable monitoring operation of the laser radar. The roof cover of the vehicle is located directly above the top of the laser radar and is equipped with an optical skylight. The optical skylight is designed with a protective cover and sealed and bonded with optical glass, which is used for the laser radar laser beam emission and the recovery of laser echo signals. There are two cabinets on the side of the laser radar and they are rigidly fixed on the UAV. One cabinet is a mobile power supply to provide power support for the laser radar, which is generally a UPS and multiple mobile power supplies; the other cabinet is a computer control processing system, which is used for laser radar control acquisition and data analysis and joint control of external devices. On the side wall of the UAV, a terminal display system is installed to display the real-time display of pseudo-color images of temperature, humidity and other data products of the temperature and humidity laser radar during the navigation process. Inside the UAV, a temperature control system and a temperature and humidity sensor system are equipped to maintain the operating environment and humidity inside the UAV in real time and ensure the operating environment of the temperature and humidity radar. The air conditioner can use variable frequency or fixed frequency models. On the top of the UAV, a Beidou positioning system is installed. The navigation positioning information is combined with the GIS map to display the temperature and humidity distribution on the navigation path. In the tail space of the UAV, a communication system is installed to facilitate external remote monitoring and control of radar equipment. Sockets are set inside the UAV at each device installation position to facilitate the power supply of the device. A charging connector is installed on the outside of the lower rear of the UAV for charging the internal mobile power supply. When in use, the mobile power source can be charged without opening the car door, which belongs to an extended implementation mode known to those skilled in the art.

Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
