Embodiment Construction

[0056] The wind direction tester of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0057] Wind direction tester of the present invention comprises measurement system, control system and rotary motion system; figure 1 with figure 2 As shown, the measurement system includes a head shell 2, which is installed on the base 1, and three groups of SM5852-015W-D pressure sensors are arranged in the head shell to measure the wind pressure on both sides of the head shell. The head shell is spliced ​​by two pieces of the same airfoil-shaped ABS plastic, and the bottom is provided with a bottom plate; the front end 21 of the head shell is a curved surface with a smooth transition to its tail end 22 (that is, a drop shape), and the head needs to ensure Smooth to reduce disturbance; the bottom plate is provided with a through hole 24. There are three sets of symmetrical through holes 23 on the wings on both sides of the head shell...

Abstract

The invention discloses a wind direction tester, and the tester comprises a measurement system, a control system, and a rotating motion system. The measurement system comprises a substrate, a head housing installed on the substrate, and at least three groups of pressure sensors which are installed at two sides of the interior of the head housing in a manner of axial symmetry. The head housing comprises a front end and a tail end, and the pressure sensors are sequentially arranged from the front end to the tail end. The rotating motion system comprises a rotating shaft, a pedestal and a servo motor. One end of a rotating shaft is connected with a substrate of the measurement system, and the other end of the rotating shaft is connected with the output shaft of the servo motor. The servo motor is disposed in the pedestal. A microprocessor of the control system receives a wind pressure signal measured by each pressure sensor, carries out the processing of each group of wind pressure signals, outputs a control signal to the servo motor, controls the forwarding and reverse rotation of the servo motor, and further controls the left and right rotation of the head housing, so as to enable the front end of the head housing to point the direction of incoming wind. The tester is good in anti-interference performance, is high in measurement precision, and is good in convenience.

Description

technical field [0001] The invention relates to meteorological measurement control, in particular to a wind direction tester and a test method. Background technique [0002] Wind direction refers to the direction from which the wind blows, and is generally represented by the method of sixteen directions. The measurement of wind direction has extensive and important applications in many fields such as experimental research, weather forecast, power station supervision, navigation, and military affairs. [0003] In engineering survey, meteorological vane is generally used to determine the wind direction in a designated area. The end of the weather vane that produces greater resistance to air flow will rotate with the wind to show the wind direction. [0004] The instruments used to measure the wind direction on the market are all based on the working principle of the wind vane. Generally, the convenience of measurement is improved by adding sensors and electronic components of...
