Embodiment
The SCM Based intelligent fan control system of one as depicted in figs. 1 and 2, comprise the temperature collect module 8 that gathers ambient temperature, for gathering the human body induction module 7 of human body information and for receiving the single-chip microcomputer 6 of temperature collect module 8 and human body induction module 7 output signals, the input end of described single-chip microcomputer 6 joins with temperature collect module 8 and human body induction module 7, the input end of described single-chip microcomputer 6 is also connected to the clock circuit 2 that is used to system that correct time benchmark is provided, be used for the reset circuit 3 of the reset function of the system that realizes, for blowing the keyboard input module of intensity and blowing type and timing function setting and for for realizing the remote control load module 5 to fan remote control, the infrared receiving head that described remote control load module 5 comprises IR remote controller and communicates with IR remote controller infrared receiving head, described IR remote controller comprises keyboard 5-1, the coding joining with keyboard 5-1 and modulation circuit 5-2 and the infrarede emitting diode 5-3 joining with coding and modulation circuit 5-2, described infrared receiving head comprises infrared receiving tube 5-4, the photoelectricity amplification module 5-5 joining with infrared receiving tube 5-4, the demodulation circuit 5-6 joining with photoelectricity amplification module 5-5, described demodulation circuit 5-6 and single-chip microcomputer 6 join, the output terminal of described single-chip microcomputer 6 is connected to for the temperature display module 9 of real-time display environment temperature value, the motor speed-regulating module 11 for sending the warning circuit of alarm sound and fan electromotor is controlled in the time that temperature being spent higher than 35.
In the present embodiment, preferred way is that described single-chip microcomputer 6 adopts STC89S52 chip.Described human body induction module 7 adopts RE200B pyroelectric infrared sensor.Described temperature collect module 8 adopts DS18B20 digital temperature sensor.Described temperature display module 9 adopts three LED nixie tubes.Described warning circuit 10 comprises buzzer.Described motor speed-regulating module 11 adopts TLC336A bidirectional triode thyristor.Voltage stabilizing chip in power module 1 adopts LM7805.
In the present embodiment, when described remote control load module 5 uses, user controls after coding and modulation circuit 5-2 from the key assignments of keyboard 5-1 input that infrarede emitting diode 5-3 is bright, the situation of going out, infrared receiving tube 5-4 will receive to such an extent that infrarede emitting diode 5-3 obtains optical signal and converts electrical signal to, be input to single-chip microcomputer 6 through photoamplifier circuit 5-5, demodulation circuit 5-6 again, single-chip microcomputer 6 just can be according to the working condition of remote signal control fan.The combination of singlechip technology and sensor technology, makes the hommization more of whole fan control system, intellectuality.
Working procedure of the present invention is: after this control system power connection, temperature display module 9 is by 3 real-time display environment temperature values of LED nixie tube, user can arrange according to the actual conditions of self minimum temperature of starting fan under the prompting of nixie tube demonstration information by keyboard input module 4 or remote control load module 5, and in fan reference rotation velocity corresponding to different room temperature grades.In the time that human body induction module 7 does not collect human body information, system is in state of dormancy.In the time that human body induction module 7 collects human body information, single-chip microcomputer 6 collects to such an extent that temperature is done corresponding processing by temperature collect module 8 digital temperature sensor DS18B20s, when the temperature collecting lower than arrange minimum temperature time, the cut-off of bidirectional triode thyristor in motor speed-regulating module 11, fan does not turn; When the temperature collecting higher than arrange minimum temperature time, single-chip microcomputer 6 calculates corresponding rotating speed in conjunction with tachometer corresponding to the minimum temperature of Current Temperatures and setting, and be converted to the square-wave pulse signal of corresponding dutycycle, thereby the angle of flow of bidirectional triode thyristor is changed, reach the object of controlling rotating speed.In the time that ambient temperature raises, the angle of flow of bidirectional triode thyristor increases, and the time of switching within the unit time is elongated, and rotating speed accelerates, otherwise in the time that ambient temperature reduces, the angle of flow of bidirectional triode thyristor diminishes, and the time of switching within the unit time shortens, and rotating speed is slack-off.When the temperature collecting is during higher than 35 ℃, the buzzer in warning circuit 10 sends tweeting sound, and prompting people should avoid heat.In the time that 10 li of warning circuits have adopted transistor base to connect low level conducting, drive buzzer, effective like this misoperation that prevents buzzer, has improved the reliability of system.User not only can select the mode of speed regulation of this intelligence, also can use a teleswitch and adjust wind speed according to ambient temperature or the impression of oneself, can also set as required the length of fan work time, so that more humane service to be provided.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation of above embodiment being done according to the technology of the present invention essence, all still belongs in the protection domain of technical solution of the present invention.
