Description
TECHNICAL FIELD
[0001] The utility model relates to environmental parameter detection technical field, concretely is a low air economic flight wind speed and direction monitoring device. BACKGROUND
[0002] In today's many fields, the accurate detection of wind speed and direction is extremely urgent, however, the existing wind speed detection technology has obvious defects. The detection signal output by many current wind speed detection devices is discontinuous, such as photoelectric detection of wind speed. The time for one rotation of the light door is used to calculate the wind speed, and the detected wind speed is the average speed of the rotation of the top measuring head. Other methods also similarly use average speed to represent fixed-point wind speed, and cannot detect the real-time wind speed of any point. When we try to analyze the wind speed change, due to the lack of continuous and complete data, it is difficult to accurately infer the important characteristics such as the increasing and decreasing trend, fluctuation amplitude and change period of wind speed at different times,
[0003] At the same time, the existing wind direction detection method also has many deficiencies. At present, many wind direction detection still relies on manual observation reading to determine the final wind direction. This requires the staff to keep focused at all times, and frequently visits the detection point for observation and recording under various complex weather conditions. On the one hand, manual observation is greatly affected by subjective factors, and different observers may have different judgments of the same wind direction due to differences in vision, judgment, etc. On the other hand, manual observation is inefficient and cannot realize real-time and continuous monitoring of wind direction. Once the wind direction changes during the observation gap, it is easy to be missed, resulting in serious lag and incompleteness of the obtained wind direction information. This backward wind direction detection method cannot meet the needs of modern society for efficient and accurate wind direction data, and an advanced and intelligent wind direction detection technology is urgently needed to replace it.

[0049] Working principle: The device is mainly composed of device shell 1, wind speed detection component 2 and wind direction detection component 3. Wind speed detection component 2 is used to measure real-time wind speed, and wind direction detection component 3 is responsible for determining the wind direction. The two components work together to convert the detected wind speed and wind direction information into electrical signals for output, facilitating user monitoring and analysis. The core component of wind speed detection component 2 is wind speed measuring head 4, which is composed of wind speed rod 7, three groups of wind cups 8 and wind speed rotating shaft 9. When there is wind blowing through the device, wind cups 8 will make circular motion around wind speed rod 7 under the action of wind force. Since the included angle between the three groups of wind cups 8 is one hundred and twenty degrees and the circular symmetry, no matter which direction the wind blows, it can make wind cups 8 rotate. The rotation speed of wind cups 8 is proportional to the wind speed, and the greater the wind speed, the faster wind cups 8 rotate. Wind speed rotating shaft 9 is connected with rotation speed detection device 6, which is the key part of wind speed measurement. It is mainly composed of rotation speed detector shell, cutting guide rod 10, two groups of brush heads 11, permanent magnet 12 and voltage detection circuit. In the rotation speed detector shell, two groups of permanent magnets 12 are fixed on both sides of wind speed rotating shaft 9, forming a constant magnetic field. When wind speed rotating shaft 9 rotates with wind cups 8, cutting guide rod 10 installed on the shaft will make cutting magnetic induction line motion in the magnetic field. According to the principle of electromagnetic induction, cutting guide rod 10 will generate induced electromotive force when cutting the magnetic induction line. The size of induced electromotive force is proportional to the motion speed of cutting guide rod 10, and the motion speed of cutting guide rod 10 is related to the rotation speed of wind cups 8, and then proportional to the wind speed. The upper and lower ends of cutting guide rod 10 are respectively provided with brush heads 11, which are electrically connected with voltage detection circuit, and the size of induced electromotive force can be measured through voltage detection circuit. The key part of wind direction detection component 3 is wind direction measuring head 5, which is composed of wind direction rod 14, wind direction marker 15 and wind direction rotating shaft 16. Wind direction marker 15 is installed at the top of wind direction rod 14, and its center of gravity coincides with the axis of wind direction rod 14. When the wind blows, wind direction marker 15 will automatically rotate under the action of wind force, so that its arrow points to the direction of the wind. This is because wind direction marker 15 has a special shape design, its head is lighter and its tail is heavier. When the wind acts on wind direction marker 15, a moment will be generated to make wind direction marker 15 rotate until wind direction marker 15 is consistent with the wind direction. Wind direction rotating shaft 16 is connected with angle detection device 13, which is mainly composed of sealed shell, encoding code disc 17, light emitter 18 and light receiver 19. Encoding code disc 17 is coaxially connected with wind direction rotating shaft 16, and when wind direction marker 15 rotates, it will drive encoding code disc 17 to rotate. In the sealed shell, light emitter 18 is located at the top and light receiver 19 is located at the bottom and corresponds to the position of light emitter 18. Encoding code disc 17 is engraved with encoding code lines, which can adopt Gray code disc or other code lines. When the light emitted by light emitter 18 passes through the rotating encoding code disc 17, the light will be modulated by the encoding code lines to form a specific light encoding signal.The light receiver 19 receives the light encoding signal processed by the encoding disc 17, and determines the spatial orientation of the encoding disc 17 through analysis and processing of the signal, and further obtains the current wind direction, without manual reading, and can realize unmanned monitoring, and provides more convenient and accurate wind direction information for low-altitude economic flight.
