Detailed Description
The following detailed description of the invention is presented in conjunction with the drawings to facilitate understanding of the invention by those skilled in the art. It should be apparent that the embodiments described below are only some, but not all embodiments of the invention. All other embodiments, which come within the spirit and scope of the invention as defined and defined by the following claims, may be made by one of ordinary skill in the art without any inventive faculty.
The utility model provides a precipitation cloud water analyte particle detector, including the flight that installs first mounting bracket on it bear the weight of the base member, be provided with precipitation cloud water analyte particle phase and size collection unit on the first mounting bracket and be used for gathering some or all through precipitation cloud water analyte particle phase and size collection unit's precipitation cloud water analyte particle charge collection unit 5.
When the method is implemented, the optimal positioning module is a Beidou positioning instrument and is used for acquiring longitude and latitude and height information of the flight bearing matrix, and the environment information acquisition module is a radio sonde which is positioned outside the flight bearing matrix and is used for acquiring temperature, humidity and air pressure of the environment.
As shown in fig. 1 and 2, the precipitation cloud water-borne particle phase and size acquisition unit comprises a body 3 which is arranged on a first mounting frame and surrounds a through cavity to form a cuboid shape, and an opening communicated with the top of the through cavity is formed in a flying bearing substrate; the body 3 is made of electrothermal glass, the inner side wall surface of the body 3 is provided with a non-hydrophilic coating, and the first mounting frame is provided with two cameras 4 which are arranged in an orthogonal mode and are respectively used for shooting pictures in the directions of two adjacent side walls of the body 3, two light source mechanisms which are arranged in an orthogonal mode and are respectively used for emitting parallel light to the other two side walls of the body 3, a power supply adjusting module for supplying power to the body 3, an environment information acquisition module, a positioning module and a control unit 12; parallel light emitted by the two light source mechanisms is parallel to the orthogonal planes of the two cameras 4 and is perpendicular to the side wall of the body 3; the precipitation cloud water analyte particle charge collection unit 5 is located the bottom of body 3, and the control unit 12 is connected with wireless communication module, power regulation module, environmental information collection module, positioning module, precipitation cloud water analyte particle charge collection unit 5 and two cameras 4 respectively.
The flying bearing matrix flies upwards in the upward direction of the through cavity, the particles drop downwards, and part of precipitation cloud water particles enter the through cavity. The through cavity is a sampling area of particles, after parallel light emitted by the light source mechanism passes through the side wall of the body 3 and passes through the through cavity, the control unit 12 controls the two cameras 4 to simultaneously acquire images of the parallel light passing through the sampling area at certain set moments, so that shadows of precipitation particles passing through the sampling area are shot down, and two orthogonal images (a group of orthogonal images) of the sampling area are obtained. And transmitting the group of images, longitude and latitude, altitude corresponding to the imaging moment, and environmental temperature, humidity and pressure information to a data receiving and processing terminal through a wireless communication module.
Because the inner side wall surface of the body 3 is provided with the non-hydrophilic coating, particles falling on the surface of the electrothermal glass are rapidly separated, so that the electrothermal glass always keeps a transparent state, and the influence on the imaging effect of the camera 4 is reduced.
In addition, the environmental information acquisition module acquires the environmental temperature information outside the precipitation cloud water analyte particle detector and sends the information to the control unit, and as the material of the body 3 is electrothermal glass, the control unit automatically adjusts the power supply current provided by the power supply adjusting mechanism to the electrothermal glass, so that the surface temperature of the electrothermal glass is controlled to be higher than the set temperature (generally 5 ℃) of the environmental temperature in time, particles falling on the surface of the electrothermal glass are evaporated, few evaporated particles do not influence the sampling result, and further, the surface of the electrothermal glass is prevented from icing or fogging, so that the imaging effect of the camera 4 is further ensured.
The resolution of the camera 4 is high, and not only precipitation particles such as raindrops, ice crystals, supercooled water drops, snowflakes, shrapnes, frozen drops, hail and the like with the diameter of 0.1-10mm can be distinguished, but also cloud particles with the diameter of 0.01-0.1mm can be distinguished.
After receiving two orthogonal images imaged at the same moment, the data receiving and processing terminal comprehensively analyzes the two orthogonal images to obtain the phase state, the size and the space position of particles in a sampling area, classifies the particles according to the phase state of the particles to obtain the number of various particles, and then obtains the spectral distribution of the various particles at a specific position (longitude, latitude and height) according to the size, the number and the positioning information of the same particles. The water content of each particle can also be obtained by combining the known densities of each type of particle according to the phase and class of the particle. And based on two sets of orthogonal images of adjacent time periods before the induced current is generatedThe falling speed v of the particles is obtained, wherein t is shooting interval time, and s is the falling distance of the particles.
Spatial coordinates of how the particles are obtained: because the two cameras 4 arranged in an orthogonal manner take pictures of the same space at the same time, the two-dimensional projection data of the X-Z coordinates of the particles are acquired by one camera 4, and the two-dimensional projection data of the Y-Z coordinates of the particles are acquired by the other camera in the three-dimensional Cartesian coordinate system X-Y-Z. And acquiring the three-dimensional coordinate of the particle by utilizing projection data of the X-Z coordinate of the particle on one image and combining the Y-Z coordinate of the particle on the Z coordinate of the same height of the other image according to the principle that the Z coordinates of the same height are the same.
In the specific judgment, since the distribution density of the particles is not large, the probability that the particles of the same type are positioned at the same X or the same Y coordinate is extremely low, so that the problem that the particles of the same type are blocked and cannot be identified is solved, and if the X-Y-Z coordinates of the two particles are the same, the particles are regarded as the same particle. The method can obtain the space coordinates of each particle in the body in the sampling area at the imaging moment.
Regarding how the phase of the particles is obtained: the data receiving and processing terminal compares the image of the particle with known fixed forms of various particles, wherein the corresponding phase with the highest similarity is the phase of the particle.
Regarding the spectrum distribution of various particles, namely, the distribution map of the number of the particles with the horizontal axis as the particle radius and the vertical axis as the particle number, the spectrum distribution map of the particles with different phases can be drawn.
The light source mechanism comprises a laser light source 1 and a lens 2 matched with the laser light source 1, wherein the lens 2 changes light emitted by the laser light source 1 into three-dimensional parallel light.
The power supply adjusting module comprises a power supply battery and a temperature controller connected with the power supply battery.
Wherein, the bottom of the flying bearing matrix is provided with a perforation for particles passing through the precipitation cloud water-borne particle charge acquisition unit 5 to pass through, so that the particles flowing through the sampling area naturally fall after passing through the bearing matrix.

When charged particles pass through the coil, the induction coil 6 generates induction current and charges the charge receiving and releasing circuit, after the charge is finished, the control unit 12 collects the charge quantity, and then controls the charge receiving and releasing circuit to discharge for the next charge, and the charge quantity, the collection time of charge quantity information and corresponding position information of each time are sent to the data receiving and processing terminal through wireless communication.
The data receiving and processing terminal combines the X-Y coordinate information of the induction coil 6 for generating the induction current, and obtains the X-Y coordinate of the particle at the bottom according to a group of orthogonal images at the moment before generating the induction current, wherein the particle which is the same as or similar to the X-Y coordinate of the induction coil 6 is the particle passing through the induction coil 6, and the charged quantity of the particle passing through the induction coil 6 is obtained. And calculates the charge quantity q of the particles,
wherein Q is 1 For the charge amount, n is the number of turns of the induction coil 6, r is the radius of the induction coil 6, L is the height of the induction coil 6, and v is the falling speed of the particles.
In addition, since the distribution density of particles is not large and many charged particles are relatively large ice-phase particles, the probability that several particles pass through the same induction coil 6 at the same time is extremely low.
As shown in fig. 4, the charge receiving and releasing circuit includes a first diode 10 whose positive electrode is connected to the first end of the magnetic induction coil and a second diode 11 whose negative electrode is connected to the first end of the magnetic induction coil, the other ends of the first diode 10 and the second diode 11 are connected to the second end of the magnetic induction coil through a capacitor and a sampling switch connected in parallel, and the connection node of the first diode 10 and the capacitor and the connection node of the second diode 11 and the capacitor are connected to the control unit 12.

In addition, the diameter of each group of induction coils 6 does not exceed 5mm so as to detect the charge quantity information of the particles with the size below 5mm, and the particles with the size greater than 5mm, such as hail, are discharged, so that inaccurate detection of the charge quantity information of the particles with the size below 5mm caused by overlarge coil radius is avoided. When a certain amount of large particles such as hail fall on the surface of the induction coil 6 and cannot pass through the induction coil 6, the frame 7 is connected with the induction coil 6 by the gravity of the large particles, and the induction coil 6 is inclined relative to the second mounting frame 8, so that the large particles fall from the surface of the induction coil 6, and the frame 7 and the induction coil 6 quickly recover to the original state under the action of the spring 9.
