The 3rd preferred version of the present invention is: described display modular comprises seven segment digital tubes and drive circuit thereof.
The 4th preferred version of the present invention is: described microprocessor comprises single chip computer AT 89C2051.
Technical conceive of the present invention is: microprocessor detects the demand setting that the user carries out through key-press module; Then according to user's demand; Utilize the Pulse wave of rotating speed testing module output to count, the controlled amount of the line of numbers of going forward side by side PID computing, and give driver module with controlled quentity controlled variable; The control rotating speed of motor, and show current rotating speed and system mode.And microprocessor utilizes internal clocking to realize user's timing needs.
Technical advantage of the present invention: adopt digital PID as control algorithm, and be core, realize constant rotational speed, the digital speed-control and digital control of electric fan, thereby make the user have more more options, safer, intelligence more with the microprocessor.
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Description of drawings
Fig. 1 is the present embodiment entire block diagram.
Fig. 2 is the scheme of installation of present embodiment electric fan and rotating speed testing module.
Fig. 3 is a present embodiment driver module circuit diagram.
Embodiment
With reference to Fig. 1, the present invention is core with the microprocessor, and the pulse of microprocessor reception rotating speed testing module output involves user's the setting and the demonstration of the output of controlling and driving module and display modular; The rotating speed testing module converts the rotating speed of motor of electric fan to Pulse wave output; Driver module receives the controlled quentity controlled variable that microprocessor is seen off, thus the control rotating speed of motor; Display modular shows current system mode and rotating speed; Button is used for the user and imports the demand of self.
Fig. 2 is the scheme of installation of rotating speed testing module on motor; Code-disc 2 is installed in the rotating shaft 3 of motor 1; And the front end of code-disc 2 is flabellums 5 of electric fan, and just in time in the groove of photoelectric sensor 4, photoelectric sensor 4 is fixed on the motor 1 by pillar 6 at the edge of code-disc 2.
Fig. 3 is the driver module circuit diagram, IC1 be optocoupler whether be used to detect the controllable silicon voltage be zero, when the controllable silicon voltage was zero, the light emitting diode of IC1 turn-offed, the voltage that then outputs to microprocessor IO2 is low, otherwise be height; IC2 is that optocoupler is used to trigger the silicon controlled conducting, when microprocessor IO1 is low level, and the lumination of light emitting diode of IC1, then silicon controlled trigger end voltage is high, the controllable silicon conducting, otherwise controllable silicon turn-offs when voltage direction commutates.
