Utility model content
The utility model is for mobile device, designed a kind of embedded anemoscope based on wireless transmission, by simplifying anemoscope design, anemoscope is become to an attached peripheral hardware of mobile device, and anemoscope is connected by bluetooth or NFC wireless mode with mobile device, by mobile device, show, store.
The utility model is the embedded anemoscope based on wireless transmission, comprises impeller, metering circuit, measurement chip, microprocessor, characterized by further comprising wireless transmission chip, and is installed in same housing.
Preferably, this impeller is high sensitivity magnetization impeller.
Preferably, housing is connected with mobile device by application specific architecture.
Preferably, described application specific architecture is 3.5mm audio connector and corresponding interface, and connected mode is affixed.
Preferably, described mobile device comprises storage and display unit, and the air speed data that described wireless transmission measures is stored, shown to mobile device;
Preferably, described mobile device embedded with bluetooth or NFC wireless communication module.
Preferably, described mobile device built-in electronic compass.
Preferably, also comprise sensor assembly.
Preferably, sensor assembly is a kind of or multiple combination arbitrarily in temperature sensor, humidity sensor, baroceptor.
The measuring wind speed scheme that the present invention adopts is to carry out special magnetization processing for high sensitivity impeller, produces magnetic effect.And for detection of the weak current that produces of the changes of magnetic field that causes for wheel rotation of wire-wound inductor change, by operational amplifier, undertaken after signal amplification, convert the variation of output frequency to, like this, the rotating speed of impeller just and chip output frequency generation corresponding relation, microprocessor only need to be measured chip frequency can calculate wheel speed, and obtains current wind speed by wheel speed and the wind speed table of comparisons.
The wind direction measurement scheme that the present invention adopts is by utilizing the built-in electronic compass of mobile device, determining wind direction in conjunction with maximum wind velocity measurement.Electronic compass for record move equipment current towards.When mobile device slowly rotates after a circle windward, orientation information and the current wind speed information of electronic compass in wind speed and direction Survey Software real-time recording unit rotation process on mobile device, by determine equipment that maximum wind velocity is corresponding towards, can obtain current wind direction.
