Description

Technical Field

[0001] This invention belongs to the field of cloud microphysical parameter observation technology in cloud precipitation theory, and specifically relates to a dual-path fog droplet spectrometer. Background Technology

[0002] Due to the current uncertainties in the theoretical understanding and parameterization schemes of cloud precipitation, the microphysical parameters of clouds have long been considered only in terms of cloud droplet condensation and gravitational collision and growth during the microphysical process of cloud formation. This has resulted in a lack of a comprehensive theoretical framework for the rapid growth of cloud droplets in nature. For example, under natural conditions, thin clouds with a thickness of 1 to 2 kilometers can form precipitation in about one hour, and the raindrops are relatively large; precipitation can also form in dense cumulonimbus clouds in about half an hour. These phenomena are difficult to explain reasonably.

[0003] Currently, various active remote sensing detection and observation technologies have been developed both domestically and internationally for measuring cloud microphysical parameters. In these ground-based and space-based remote sensing detections, when using the detected power spectrum data to invert and obtain cloud microphysical parameters, the inversion process requires assumptions about cloud droplet spectra and particle characteristics, typically assuming a gamma distribution. This makes it impossible to obtain the true distribution and number concentration of cloud droplets, and the measurement accuracy needs verification. In collision sampling measurement methods, particles larger than 100 μm break up upon impact with the film, and the impact process destroys particle characteristics. Therefore, this method has high accuracy when measuring particles with diameters from 10 μm to 100 μm, but it is difficult to measure smaller or larger particles. In direct imaging and shadow projection measurement methods, photographic techniques are used to obtain cloud particle images on the image plane or particle grayscale distribution on an optical array probe. Image detection and processing techniques are then used to obtain cloud microphysical parameters such as particle morphology, diameter, and particle spectrum. However, this method can only obtain a two-dimensional integral effect of the particle image along the measurement path, and cannot obtain the three-dimensional cloud particle distribution, thus failing to obtain concentration information. In addition, existing droplet detection equipment is easily affected by the ambient temperature during practical application. When the temperature is too low, it can affect the accuracy of the sampling equipment, and in severe cases, it can even affect the normal operation of droplet detection. Summary of the Invention

[0021] Example 1

[0022] This embodiment provides a method such as Figures 1-5The dual-channel droplet spectrometer shown includes a main body 1. An air inlet 2 is located on the front side of the main body 1, and a first air outlet 3, a connecting port 5, and a second air outlet 6 are located on the rear side of the main body 1. The air inlet 2 and the first air outlet 3 are positioned opposite each other. A fan 13 is installed inside the main body 1. The air inlet of the fan 13 corresponds to the connecting port 5, and the air outlet of the fan 13 corresponds to the second air outlet 6. The first air outlet 3 and the connecting port 5 are connected by a duct 4. The main body 1 also includes a duct assembly 8. One end of the duct assembly 8 is connected to the air inlet 2, and the other end is connected to the first air outlet 3. Four mounting seats 18 are located on the side wall of the duct assembly 8. Each of the four mounting seats 18 houses a first laser 9, a second laser 10, a first camera 11, and a second camera 12, respectively. The first laser 9 corresponds to the first camera 11, and the second laser 10 corresponds to the second camera 12.

[0023] Furthermore, the main body 1 is also provided with a power module 14 and a control component 15. The power module 14 is electrically connected to the first laser 9, the second laser 10, the first camera 11, the second camera 12, the fan 13, and the control component 15, respectively, to provide the electrical energy required for the operation of each component. The control component 15 is electrically connected to the first laser 9, the second laser 10, the first camera 11, the second camera 12, and the fan 13, respectively. The control component 15 controls and adjusts the working status of the first laser 9, the second laser 10, the first camera 11, the second camera 12, and the fan 13.

[0024] Furthermore, an air intake pipe 7 is also provided at the air inlet 2, and the air intake pipe 7 passes through the air inlet 2 and is connected to one end of the air duct assembly 8.

[0025] Furthermore, the air intake pipe 7 is provided with a heating component 19. Preferably, the heating component 19 is a heating element installed inside the air intake pipe 7. A temperature sensor 20 is provided on the outer wall of the main body 1. When the outside temperature is lower than the set temperature, the heating element starts to heat the inner wall of the air intake pipe 7. At the same time, a temperature sensor is also installed on the inner wall of the air intake pipe 7 to ensure that the air inlet temperature is maintained at the set temperature.

[0026] Furthermore, the main body 1 is also equipped with a first optical transceiver 16 and a second optical transceiver 17; the first optical transceiver 16 is connected to the first camera 11; the second optical transceiver 17 is connected to the second camera 12 and can convert the collected information from electrical signals to optical signals for remote transmission.

[0027] When the dual-channel droplet spectrometer is working, the temperature sensor 20 on the main body 1 detects the external ambient temperature. When the ambient temperature is lower than the set temperature, the control component 15 controls the heating element to start heating the inner wall of the suction pipe 7, thereby raising the temperature of the air drawn into the suction pipe 7. This ensures that the internal ambient temperature of the air duct component 8 is at the temperature at which the first laser 9, the second laser 10, the first camera 11, and the second camera 12 can operate normally. At the same time, the first laser 9, the second laser 10, the first camera 11, and the second camera 12 perform dual-channel simultaneous detection of the drawn-in air, enabling the detection of droplets and particles in the air to obtain three-dimensional cloud particle distribution and thus obtain the concentration information of particles in the air. Moreover, the dual-channel droplet spectrometer is equipped with a first optical transceiver 16 and a second optical transceiver 17, which can convert the particle image information collected by the first camera 11 and the second camera 12 into optical signals that are easy to transmit over long distances. This eliminates the need for personnel to collect data at the setting point of the dual-channel droplet spectrometer, saving manpower and avoiding dangerous situations for personnel in cold environments.

[0028] In summary, this dual-channel droplet spectrometer can heat the ambient air before it is drawn in, ensuring that the air temperature is maintained at the normal operating temperature of the spectrometer. This prevents the spectrometer from malfunctioning due to excessively low ambient temperatures, allowing it to adapt to colder working environments and ensuring the accuracy of droplet monitoring. Furthermore, the spectrometer is equipped with dual-channel detection devices, enabling the detection of airborne particles from two angles, obtaining three-dimensional cloud particle distribution, and thus acquiring information on the concentration of airborne particles.

[0029] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
