Technical field
The utility model relates to a kind of wind speed and direction measuring device based on magnetic field detection.
Background technology
Current various fields all relates to the measurement of wind speed and wind direction, such as commercial Application, environmental monitoring and room air adjusting etc.Air velocity transducer is a Primary Component of realizing that wind speed and direction is measured.Traditional anemoscope spare is mechanical type vane and weathervane, but traditional mechanical type air velocity transducer structure is bigger, and is subjected to easily that sleet is freezing etc. to be influenced, and needs constantly to safeguard.Novel wind-speed sensor such as ultrasonic wind speed sensor, hot type air velocity transducer etc. have the incomparable advantage of mechanical wind gage.But typical ultrasonic air velocity transducer is because emission and detection receive a stationkeeping, and structure is relatively large.The subject matter of hot type air velocity transducer is the influence that is subjected to environment temperature and humidity easily, and power consumption is bigger than normal.In recent years the exploitation based on the MEMS(micromachined) though the hot diaphragm type air velocity transducer device size of technology is very little, also exist measurement range little, shortcomings such as installation requirement harshness.
The utility model content
The purpose of this utility model provides a kind of highly sensitive, wind speed and direction measuring system signal pickup assembly that system bulk is little, simple in structure, easy to install.
The technical solution of the utility model is: a kind of wind speed and direction measuring device based on magnetic field detection, it is characterized in that, comprise base, be arranged at magnetic field sensor and support on the base, be vertically installed in the wind sensitive rod of base top, described wind sensitive rod one end is provided with permanent magnetic material, and the other end is stiff end and is fixed on the described support; Described magnetic field sensor is at least three, and the line of adjacent two magnetic field sensors is formed equilateral, and described permanent magnetic material and each magnetic field sensor equidistantly are provided with.
As a kind of improvement of the present utility model, described magnetic field sensor is four.
As a kind of improvement of the present utility model, the distance of described magnetic field sensor and described permanent magnetic material is between 1mm to 30mm, and the distance between the two relative magnetic field sensors is between 16mm to 50mm.
Wind sensitive rod described in the utility model be length at 10mm between the 30mm, diameter at 2mm to the elastic rod between the 3mm.Described elastic rod is the good material of elasticity, for example the right cylinder made of elastomeric material.
The utility model is a kind of wind speed and direction measuring device based on magnetic field detection, and wherein the stiff end of wind sensitive rod is arranged on the support, under the calm situation, does not swing perpendicular to the wind sensitive rod of base, and the relative position of permanent magnetic material and magnetic field sensor is constant.When wind sensitive rod during at the wind action lower swing, the also change of the position of the permanent magnetic material that is fixed thereon, like this, the distance of permanent magnetic material to four magnetic field sensor just can change, and the signal power that magnetic field sensor receives also can change.By measurement to each magnetic field sensor signal power, amplify the back through signal amplification circuit again and give computing machine or microcontroller by the analog digital conversion, computing machine or microcontroller calculate the signal difference Vx=V1-V3 and the Vy=V2-V4 of two magnetic field sensors separately of x direction and y direction on the plane, V1 wherein, V2, V3, V4 is respectively magnetic field sensor 1,2,3,4 output signals after amplifying.Utilize trigonometric function to concern that tanq=Vx/Vy calculates wind direction again, utilization (Vx) 2+ (Vy) 2 calculates and provides the size of wind speed and exports the result.
The relevant knowledge of the simple solid geometry of the utility model utilization, only adopted the wind sensitive rod that is provided with permanent magnetic material and four magnetic field sensors just reached can measuring wind the purpose of energy measurement wind direction again, mechanical elasticity wind sensitive rod structure and magnetic induction sensor are organically combined, improved measurement sensitivity.Compare with traditional ultrasonic air velocity transducer system, simple in structure, volume is little, compares with the hot blast speed sensors, does not have problems such as temperature drift, uses and easy for installation.
