Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, a kind of wind speed pick-up unit of the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to shown in Figure 1, Fig. 1 is the structured flowchart of a kind of wind speed pick-up unit of the utility model, comprises wind speed sensing unit 1, microprocessor 2, and power supply 3; Wherein, wind speed sensing unit 1 comprises fan 11, sensor 12; The flabellum of fan 1 is provided with magnetic material 111; Sensor 12 is provided with Hall element 121.
Referring to Fig. 2, Fig. 2 is the circuit theory diagrams of the sensor of the utility model.
Wherein " SIG " is signal output part, output pulse signal to microprocessor 2.
The level signal that Hall element 121 produces is converted into pulse signal after illustrating circuit, this pulse signal is a square wave.Then, pulse signal is linked into the signal input part of microprocessor 2.The frequency of this pulse signal can characterize the rotating speed of fan 11.Because wind speed is fast more, then rotation speed of the fan is fast more, so rotation speed of the fan can directly characterize wind speed.
Microprocessor 2 is handled this pulse signal after receiving said pulse signal, and the result after will handling and predefined wind speed threshold value compare, and when wind speed is too small or excessive, all starts alert program.The wind speed threshold value can freely be set and revised by the user, to satisfy the actual demand in the practical applications.
Microprocessor 2 is preferably single-chip microcomputer, also can use other programmable microprocessors.
Wind speed sensing unit 1 all is an electrifying device with microprocessor 2, therefore needs to be connected with power supply 3.
This wind speed pick-up unit is arranged at the air inlet or the air outlet of blower fan; After the air intake machine starts; Air-flow promotes flabellum and rotates through the flabellum of passing through fan 11, and the rotation of flabellum drives magnetic material 111 rotations on the flabellum; Hall element 121 on the sensor 12 detects the rotation period of magnetic material 111; Signaling conversion circuit 122 sends the square wave of corresponding frequencies, and microprocessor 2 collects the square wave that wind speed sensing unit 1 sends, through just can know the flabellum rotating speed of fan 11 to the judgement of square wave frequency; Because its rotating speed directly receives air intake machine air-out velocity effect, so just can judge air-out speed and the duty of air intake machine indirectly from the rotating speed of wind speed sensing unit.
