[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose, the specific implementation methods, structural features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and examples.

[0020] The following will be combined with the drawings in the embodiments of the patent of the present invention to clearly and completely describe the technical solutions in the embodiments of the patent of the present invention. Obviously, the described embodiments are only part of the embodiments of the patent of the present invention, not all of them. Based on the embodiments in the patent 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 patent of the present invention.

[0021] In the description of the patent of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "aligned", "overlap", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the patent of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the patent of the present invention.

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention patent, unless otherwise specified, "plurality" means two or more.

[0023] Figure 1 The drone-mounted holographic cloud drop spectrometer shown in the figure comprises a shell 1 with an elliptical cross section, the top surface of the shell 1 being perpendicular to the major axis of the ellipse of the cross section, the top surface being fixed with two first supporting arms 2 and second supporting arms 3 arranged opposite to each other, and a side surface perpendicular to the minor axis of the ellipse of the cross section of the shell 1 being provided with Figure 1 The airborne mounting base 4 shown. Figure 1 It is not difficult to see that the overall six-line design of the drone-mounted holographic cloud drop spectrometer greatly reduces wind resistance while reducing the impact on particle breakage, ensuring the accuracy and reliability of monitoring. And by setting the airborne fixing seat 4 on one side of the shell 1, it is convenient for the entire drone-mounted holographic cloud drop spectrometer to be installed in parallel with the drone without interfering with each other, and it is convenient for installation or disassembly, maintenance, etc.

[0024] Depend on Figure 2 It can be seen that the first protective cover 5 and the second protective cover 6 are respectively arranged on the relative inner sides of the free ends of the first support arm 2 and the second support arm 3 away from the shell 1; a first 45° angle reflector 7 is arranged at the connection between the first protective cover 5 and the first support arm 2; a second 45° angle reflector 8 is arranged at the connection between the second protective cover 6 and the second support arm 3, and a reflector cover plate 15 is arranged outside each 45° angle reflector to realize the installation support and protection of the reflector.

[0025] Window glass 9 and an electric heating ring 10 located inside the window glass 9 are provided at the light entrance of the first protective cover 5 and the second protective cover 6 to heat the air in the monitoring area when the temperature is low, so as to avoid the adverse effect of low temperature on monitoring.

[0026] The first protective cover 5 is provided with a lens 11 located on the incident light path of the first 45° angle reflector 7, such as a 3x lens, which can pre-magnify the particles incident on the camera 13 by an appropriate multiple, which is suitable for small particle detection.

[0027] A laser assembly 12 is disposed in the second support arm 3 , a camera 13 is disposed in the first support arm 2 , and a light barrier 14 is disposed in the first support arm 2 at the light entrance of the camera 13 .

[0028] Then by Figure 2 It can be seen that a battery compartment 16, a control circuit board 17 (assembled on the outside of the battery compartment 16 through a mounting bracket), a memory 18 and an RS422 communicator 19 are provided in the shell 11; the battery compartment 16 and the memory 18 are electrically connected to the control circuit board 17 respectively; the RS422 communicator 19 is connected between the camera 13 and the memory 18; the battery compartment 16, the control circuit board 17 and the memory 19 are distributed along the axial direction of the shell 11, and the mounting bracket of the control circuit board 17 is assembled on the outside of the battery compartment 16. Such an arrangement can maximize the utilization of the inner cavity space of the shell, so that all components are laid out reasonably and compactly, which is conducive to reducing the volume of the shell and facilitating installation, disassembly and subsequent inspection and other maintenance operations.

[0029] In this embodiment, the memory 18 is located at one end of the camera 13, and the corresponding end of the housing 1 at this end is provided with a USB interface 20, a memory power switch 21 and a Type-C interface 22 respectively connected to the memory 18.

[0030] A battery compartment cover 23 is disposed at the other end of the housing 1 opposite to the end where the camera 13 is located, and a battery compartment cover 23 is disposed at the bottom end of the housing 1. Figure 2 or Figure 3 The external power interface 24 shown; Figure 3 As shown, a RS422 communicator interface 25 is provided on one side of the cabin 1 located at the center of the airborne fixing seat 4, so as to facilitate docking with the communication line on the drone.

[0031] It is not difficult to see from the above embodiments that the overall shape of the provided drone-mounted holographic cloud droplet spectrometer is streamlined in design, which reduces wind resistance, especially reduces the breakage of particles, ensures the authenticity of the detection data, and magnifies the particles by an appropriate multiple through the lens, which greatly improves the accurate detection of small particles, and is conducive to improving the detection accuracy and reliability of the entire cloud and fog measuring instrument.
