three.workprinciplebrief introduction

1、The wind direction part is supported by the retainer protecting the wind cup。From the wind vane、windRadial axis andwindtowardsdegreeIt is made up of plates, etc，Installed inwindtowardsdegreeThe magnetic bar on the disk andwindtowardsdegreeThe magnetic compass is composed of a magnetic compass, which is used to determine thewindtowardslocation。WhenRotation inwindtowardsdegreeTray nut under disc housingTime，Tray handlewindtowardsdegreeHold up or put down the tray，Make the rudiment bearing away from or contact with the shaft tip。windtowardsThe indicated value is determined bywindtowardsPointer inwindtowardsdegreeTo determine the stable position of the disk。

2、wind speedThe sensor uses the traditionalthreeCup rotating frame structure.It willwind speedIt is linearly transformed into the rotation speed of the rotating frame.In order to reduce the startup timewind speed，Lightweight plastic air cup，Tapered bearing support，The shaft of the rotating frame is fixed with aoneA toothed leaf blade，WhenThe rotating frame is on the waywindrotateTime，The shaft drives the blades around，The toothed blade continuously cuts the light beam in the light path of the photoelectric switch，So thatwind speedLinear conversion to the output pulse frequency of the photoelectric switch。

Single chip microcomputer in the instrumentwindThe output frequency of the sensor is used for sampling、calculation。Post instrument outputInstantaneous wind speed，oneminuteAverage wind speed、Instantaneous wind level、oneminuteAverage wind level，Average wind levelwindlevelCorrespondingWave height。The measured parameters are displayed directly on the LCD of the instrument。

In order to reduce the power consumption of the instrument，The sensor and single chip microcomputer in the instrument have taken special measures to reduce the power consumption。In order to ensure the reliability of data，The instrument also containssupply voltageDetection circuit。Whensupply voltageAt the bottom3.3VaboutTime，Instrument display“Under voltage”，Prompt userssupply voltageTaidi data is no longer reliableTimeReplace the battery。The instrument is also equipped with a power control circuit，Using electric circuit to replace mechanical switch to control the power on and off of instrument。
