Embodiment 2

[0194] The rest are the same as in Embodiment 1, the difference is that the reduction device adopts planetary gear reduction, as shown in Figure 11, there are two circles, one large and one small, in the figure, the two circles are concentric, and the annular part between the two circles has another Three small circles, the largest of all circles is the inner gear ring, the other four small circles are gears, the middle one is called the sun gear, and the other three small circles are called planetary gears. The shaft connecting the wind cup and the reduction unit drives the sun gear of the reducer, and the sun gear drives the planetary gear supported on the inner gear ring, and the planetary gear drives the output shaft connected to the outer gear ring through its meshing transmission with the outer gear ring , to achieve the purpose of deceleration. The planetary gear is designed as an upper closed type, and the closed end is upward, and a red fluorescent pointer is sprayed ...

Embodiment 3

[0196] The rest is the same as in Embodiments 1 and 2. The energy generated when the wind cup rotates is used to generate electricity, and the generated electric energy provides energy for the machine vision detection unit to realize high-quality measurement of wind speed and direction without power consumption.

Embodiment 4

[0198] The rest are the same as in Embodiments 1 and 2. The solar cells are used to generate electric energy, which is connected to the storage battery by a conventional charging circuit, and then a stabilized power supply is generated by a voltage stabilizer to realize high-quality measurement of wind speed and direction without power consumption.

Abstract

The utility model discloses a three-dimensional wind measuring unit based on a comprehensive vision, which comprises a bracket, an omni-directional vision sensor and a microprocessor for detecting wind speed and wind direction. A wind cup, a reducing mechanism, a fixed connecting link, a wind mark and a wind direction orientation block are arranged in the horizontal direction and the vertical direction of the bracket. The wind cup is fixedly connected with the upper side of the input shaft of the reducing mechanism, while the lower end of the input shaft of the reducing mechanism is sleeve-jointed on the upper end of the fixed connecting link. The wind mark is sleeved on a connecting shaft; the connecting shaft is fixedly connected with the lower end of the fixed connecting link; the wind direction orientation block is arranged at the end of the wind mark; the upper end of the wind direction orientation block is positioned at the same plane with the reducing mechanism. Two pointers are respectively positioned on the input shaft and the output shaft of the reducing mechanism, and the upper end of the two pointers and the wind direction orientation block are provided with marker color. The visual range of the vision sensor comprises the plane where the vertical direction and the horizontal direction of the reducing mechanism are positioned. The utility model has the advantages of high-precision, high sensitivity, long-term reliability, high reliability in test results and effective test of 3D wind speed and direction detection.

Description

technical field [0001] The invention belongs to the application of computer image processing technology, three-dimensional wind speed and wind direction visualization technology and mechanical design technology in wind speed and wind direction detection, and is mainly applicable to the fields of meteorology, ocean, environment, agriculture, water conservancy, electric power, military, airport, scientific research, cultural relics protection, etc. . Background technique [0002] Wind field measurement includes wind speed and wind direction. An ideal wind field measurement sensor should be able to determine a three-dimensional vector. However, there are great difficulties in the development and calibration of 3D vectors. Therefore, the general wind field measurement sensors determine two-dimensional vectors, which are generally considered as (xy plane) two-dimensional vectors, wind speed-modulus and wind direction-direction. In some special cases, vertical motion is also qui...
