3, reduce user and occur uncomfortable symptom and sick;
4, the injury of the wind-force of minimizing constant current to health;
5, applicable crowd and scope are wide, comparatively human oriented design.
Accompanying drawing explanation
Fig. 1 is the bright schematic diagram of this law.
Embodiment
The temperature AT89C51 single-chip microcomputer (3) of accepting by detection DS18B20 Temperature sampler (1) is processed accordingly, can utilize button to pass through LED nixie tube and show (2) temperature upper limit t1 lowest temperature t2, when temperature is during higher than t1, wind speed is the top speed that electric fan (5) provides, when temperature is during lower than t2, AT89C51 single-chip microcomputer (3) pin output low level, electric fan (5) does not have electric current to pass through, stop operating, when temperature is between t1 and t2, utilize certain function effect room temperature measured value, given electric fan (5) friction speed, motorized motions module (4) adopts simple H bridge circuit,
Below illustrate the effect of each parts.
DS18B20 Temperature sampler (1), DS18B20 can meet the measuring range from-55 degrees Celsius to+125 degrees Celsius, and DS18B20 measuring accuracy is high, value added on products is 0.5 degree Celsius, in one second, temperature inversion is become to numeral, being stored in the RAM of two eight of the temperature value recording, single-chip microcomputer directly therefrom sense data to convert the decimal system to be exactly temperature, easy to use.DS18B20 digital temperature sensor is realized " one-wire bus " interface, and temperature-measuring range (55 ~+125 ℃), under the condition of general normal room temperature, is accurate to ± 0.5 ° of C.Scene temperature, directly with the digital form transmission of " one-wire bus ", has improved the anti-interference of system greatly.
LED nixie tube shows (2), adopts four 8 segment numeral pipes as display screen, because room temperature may be at most only double figures, so four digital suckers are enough, selects the compositions such as four eight sections of common anode nixie tubes, positive-negative-positive triode, resistance.Nixie tube shows employing dynamic display types, by AT89C51 single-chip microcomputer (3) P0 mouth, is carried and is shown character, by P2.3-P2.7, provides chip selection signal, by triode 8550, provides driving.
