[0034] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] In this embodiment, the full-angle visibility meteorological detection device is capable of detecting visibility and current weather phenomena at all angles.

[0036] like Figures 1 to 10As shown, the full-angle visibility meteorological detection device includes a detection box 10, four groups of optical signal transceiver modules 20, a meteorological detection component 30 and a central control mainboard 40.

[0037] The detection box 10 includes a box body 11 and an upper cover 12. The box body 11 is a rectangular parallelepiped structure with an opening at the top. The interior of the rectangular parallelepiped structure is a cavity, and a mounting plate 13 is fixed at the bottom, and a fixing column 14 is vertically fixed on the mounting plate 13.

[0038] The rectangular parallelepiped structure has four side elevations, each of which has two circular openings 15. The circular openings 15 have grooves. A heating module 16 is also provided on the inner side of each side elevation. The heating module 16 is laid on the inner side of each side elevation and surrounds the circular opening 15. The heating module 16 is a heating resistance wire.

[0039] In this embodiment, the box body 11 is a rectangular parallelepiped structure with four side elevations. In other embodiments, other polyhedral structures can be used according to actual needs and conditions, so that the box body has three side elevations or more side elevations.

[0040] The upper cover 12 covers the opening at the upper end of the box body 11 and has an opening at the center.

[0041] The number of signal transceiver modules 20 corresponds to the number of side elevations of the box 11, which is four groups. The four groups of optical signal transceiver modules 20 are respectively arranged on the openings on the four side elevations of the box 11. The structures and connection relationships of the four groups of optical signal transceiver modules 20 are the same, and one group is taken as an example for detailed description below.

[0042] An optical signal transceiver module 20 includes two lenses 21, a laser transmitter 22, and a laser receiver 23. The two lenses 21 are respectively engaged with the two circular openings 15 on a side elevation of the box body 11 through the grooves on the circular openings 15. A waterproof sealing ring 24 is provided between the lens 21 and the circular opening 15.

[0043] The laser transmitter 22 is an infrared LED laser transmitter. The laser receiver 23 is a PIN photodiode. The laser transmitter 22 and the laser receiver 23 are respectively fixed on the inner side of each side elevation through screw threads and are respectively located on the rear side of the two lenses 21.

[0044] In this embodiment, a set of optical signal transceiver modules includes two lenses, and the laser transmitter and the laser receiver are respectively located at the rear side of the two lenses. In other embodiments, according to different actual conditions, a set of optical signal transceiver modules may include only one lens, and the laser transmitter and the laser receiver are simultaneously located at the rear side of one lens.

[0045] The meteorological detection component 30 includes at least two rounded rectangular metal rings 31. The metal rings 31 serve as the positive and negative electrodes of the meteorological detection component 30. The meteorological detection component 30 is based on the capacitive detection principle. Since the relative dielectric constants of air, distilled water, ice, and snow are different (air: 1.0006, distilled water: 81, ice: 3-4, snow: 1-2), the meteorological detection component 30 distinguishes the surface state (no covering, distilled water, ice, snow) by detecting the different dielectrics of the surface materials covering the meteorological detection component 30, and judges the weather phenomenon according to the visibility value obtained by measurement.

[0046] In this embodiment, the weather detection assembly 30 includes five rounded rectangular metal rings 31. The five metal rings are concentric and arranged in sequence from the inside to the outside along the opening in the center of the upper cover 12. Among the five metal rings 31, the first, third, and fifth metal rings from the inside to the outside are the positive poles of the weather detection assembly 30, and the second and fourth metal rings are the negative poles of the weather detection assembly 30.

[0047] A waterproof sealing ring 32 is provided at the position where the metal ring 31 contacts the opening of the upper cover 12 .

[0048] A flat cable 33 is connected to the weather detection component 30 located on the inner side of the upper cover 12 , and the weather detection component 30 is electrically connected to the central control mainboard 40 through the flat cable 33 .

[0049] The central control mainboard 40 is mounted on the mounting plate 13 through the fixing columns 13. The central control mainboard 40 is a device having a central control PCB board and a central control processor, such as a single chip microcomputer, a host computer or an editable logic controller.

[0050] The central control mainboard 40 is provided with an optical signal processing circuit 41, a meteorological signal processing unit 42, an optical signal driving unit 43, a processing module 44, a storage unit 45 and a wireless transceiver unit 46. The optical signal processing circuit 41 and the optical signal driving unit 43 are electrically connected to the optical signal transceiver module 20, and are used to drive the optical signal transceiver module 20 and process the laser signal collected by the optical signal transceiver module 20. The meteorological signal processing unit 42 is electrically connected to the meteorological detection component 30, and is used to process the dielectric constant detected by the meteorological detection component 30. The processing module 44 is used to process various collected information data.

[0051] The storage unit 45 is a TF memory card for storing data.

[0052] A built-in antenna is provided on the upper cover 12. The wireless transceiver unit 46 is a NB-Iot wireless module, which can be wirelessly connected to an external terminal (such as a monitoring center, a mobile phone, an APP, etc.) to transmit the stored or detected data.

[0053] The heating module 16 is electrically connected to the central control mainboard 40 via a wire, and performs heating under the control of the central control mainboard 40 .

[0054] The detection process of the full-angle visibility meteorological detection device is as follows: the four infrared LED laser transmitters in the four groups of optical signal transceiver modules 20 are driven at different frequencies to emit lasers outward at a direction of 90°. The lasers are scattered by the outside air, and then the four PIN photodiodes receive the scattered light at an angle of 60° after the suspended matter in the air emits light; the metal ring 31 of the meteorological detection component 30 detects the dielectric of the material covering the surface of the metal ring 31 to detect whether there is rain, snow, or ice; then the central control motherboard 40 aggregates the four received optical signals, calculates the visibility value, and judges the weather phenomenon according to the detection result of the metal ring 31, and saves the data to the local TF card, or sends the data to the external terminal through NB-Iot as needed.

[0055] During the above detection process, when it is detected that the ambient temperature of the detection box 10 is too low and condensation causes damage to the equipment, the central control motherboard 40 controls the heating module 16 to turn on the heating function to prevent measurement value deviation caused by condensation on the circular opening 15.

[0056] According to the full-angle visibility meteorological detection device in the above embodiment, the detection box includes a box body and an upper cover, and a plurality of optical signal transceiver modules and a central control mainboard are all arranged on the detection box. At least one opening is arranged on the side of the box body, and a plurality of optical signal transceiver modules are arranged on the opening. The central control mainboard is electrically connected to the plurality of optical signal transceiver modules, and the central control mainboard processes the signals detected by the optical signal transceiver modules. Based on the above structure, since the plurality of optical signal transceiver modules and the central control mainboard are all arranged on the detection box, the structure of the device is compact and easy to install, and there are not many requirements for the installation environment. The sampling volume of visibility is large, and full-angle measurement can be achieved with high measurement accuracy. In addition, openings are arranged on the sides of the box body of the detection box. Therefore, as long as one direction of the detection box is unobstructed, the optical signal transceiver module can perform detection and measure the visibility value.

[0057] In addition, there are four optical signal transceiver modules, corresponding to the openings on the side of the box. Each optical signal transceiver module includes a laser transmitter, a laser receiver and a lens, and can measure visibility values ​​at all angles.

[0058] In addition, two openings may be provided on each of the four sides of the box, and a lens may be provided on each opening. Then the laser transmitter and the laser receiver may be respectively provided on the rear sides of different lenses, so that the measured visibility value is more accurate.

[0059] In addition, the full-angle visibility meteorological detection device also includes a meteorological detection component, which is arranged on the upper cover and electrically connected to the central control main board. Therefore, the full-angle visibility meteorological detection device can detect weather phenomena, making the full-angle visibility meteorological detection device more widely applicable.

[0060] In addition, the meteorological detection component includes at least two metal rings, which use the capacitive detection principle to detect current weather phenomena based on the different relative dielectric constants of air, water, snow and ice.

[0061] In addition, a heating module is provided on the inner side of the box, which can heat the box to avoid damage to the equipment caused by some harsh environments. At the same time, it can also prevent measurement deviations caused by the surrounding environment to the measuring device.

[0062] In addition, an optical signal processing circuit, a meteorological signal processing unit, and an optical signal driving unit are provided on the central control main board. The optical signal processing circuit, the optical signal driving unit and the optical signal transceiver module are electrically connected; the meteorological signal processing unit is electrically connected to the meteorological detection component. Therefore, the main control main board can process the signal according to the measured data to obtain the current visibility value and weather phenomenon.

[0063] In addition, the central control motherboard is also equipped with a storage unit and a wireless transceiver unit, which can store the detection data to prevent the loss of measurement values ​​due to wireless communication failure. At the same time, the wireless transceiver unit can transmit data to the outside, making the device more flexible and practical, and making the device portable enough for easy use.
