Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is described in further detail:
As shown in Figure 1, a kind of fan control system with intelligent temperature control and anti-theft feature, comprises and is arranged on micro-control module on fan and connected temperature detecting unit, speed adjustment unit, supply module, infrared induction unit, alarm module; Described micro-control module comprises the first parameter comparison unit, the first control unit, the second parameter comparison unit and the second control unit;
Wherein, temperature detecting unit, for detecting the temperature parameter of fan circumference environment in real time;
Infrared induction unit, for detecting the fan circumference information parameter whether someone exists;
First parameter comparison unit, comparing for the temperature parameter that detected by temperature detecting unit and normality threshold, when exceeding normality threshold, sending a signal to the first control unit;
First control unit, for the signal sent according to the first parameter comparison unit, starts speed adjustment unit and controls fan acceleration rotation;
Second parameter comparison unit, for the information parameter of infrared induction unit inspection and normality threshold being compared, when exceeding normality threshold, sends a signal to the second control unit;
Second control unit, for the signal sent according to the second parameter comparison unit, controls alarm unit and gives the alarm.
Wherein, the model of described infrared induction unit is BISS0001, and described alarm unit is acousto-optic warning unit, and described micro-control module is AVR single chip, and the model of described temperature transducer is DS18B20, and described acousto-optic warning unit comprises loudspeaker and a LED.
Wherein, this system also comprises an infrared induction unit, described infrared induction comprises human body passive infrared probe, Fresnel lens, special chip BISS0001, wherein infrared induction unit is used in real-time sensing chamber whether somebody exists, and then controlling the opening and closing of fan, this system is also provided with a burglar alarm module; When starting alarm mode, for sending continuous print alarm signal when detecting in its region and having people, described micro-control module is AVR single chip, and the model of described temperature transducer is DS18B20, described burglar alarm module is acoustooptic alarm module, comprises loudspeaker and a LED.
Release human body infrared by AVR single chip and heat and come whether have people in surveyed area, if have people to occur within the scope of distance infrared induction unit 5-7 rice, then it can export high level, then by detecting to the low and high level of the single-chip processor i/o mouth that induction module connects to carry out corresponding operation.In the normal mode, if there is people to occur, system then can light intensity always in sensing chamber and temperature, and by carrying out intelligent control compared with setting value: if dark, then open two LED; If light is general, then open a LED; If light is comparatively strong, then select not turn on light; And if temperature is lower than setting value, then do not open fan; If temperature is higher than setting value, open fan; If temperature too high (native system is set to 40 degree), then can send the sound of warning.If in the normal mode nobody occur, namely when human body induction module output low level, system then closeall consumer (LED, fan) to save electric energy.In addition switch current mode of operation by button, if start burglar alarm pattern, when detect in its region have people or temperature higher than a certain setting value time, continuous print alarm signal will be sent, until button presses just stop alarm.
Infrared induction element circuit forms primarily of human body passive infrared probe, Fresnel lens, special chip BISS0001, when the detecting area having people to appear at it, sensor just can detect signal and signal is passed to single-chip microcomputer, single-chip microcomputer by detect output signal again according to actual conditions whether this unlatching device and equipment or allow the electric equipment in room be in one can opening state.
BISS0001 be by operational amplifier, voltage comparator, state controller, retard time timer and the numerical model analysis specific integrated circuit that forms such as blocking time timer.When in the infrared rays of human body radiation to be focused on pyroelectric infrared sensor detection unit by Fresnel lens, sensor in circuit is by output voltage signal, then the band-pass filter that this signal is first made up of C1, C2, R1, R2 by is made, the upper cut-off frequency of this wave filter is 16 Hz, and lower-cut-off frequency is 0.16 Hz.
Due to the detected signal voltage very faint (usually only having about 1 mV) that infrared induction unit exports, and be the signal of a change, the effect of Fresnel lens simultaneously makes again output signal voltage be that (frequency of pulsed voltage is determined by the travelling speed of testee pulse shape, be generally O.1 Hz ~ 10 about Hz), so the voltage signal that reply heat releases infrared senor output carries out secondary amplification by operational amplifier OP1 and OP2.After two-way amplitude discriminator process again via voltage comparator COP1 and COP2 formation, detect effective trigger signal Vs deactivation timer retard time.
The software debugging part of fan control unit, originally be keep in mind to utilize the mode of PWM speed governing to regulate the rotating speed of fan, thus the predefined function of three different rotating speeds, temperature performs function at a slow speed between 27-28 °, temperature performs middling speed function at 28-30 °, temperature performs quick function at 30-40 °, find when just having started debugging that fan really can according to Current Temperatures self-regulating rotary speed, at this moment the character of display does not but change on 1602, namely it can not reflect current pattern and room temperature in real time, at this moment just consider it is that cyclical function is out of joint, carefully see that time cyclical function just finds this is because system enters the endless loop of fan speed-regulating, and the pattern of outside, temperature scanning and display routine but do not circulate execution, when removing fan speed-regulating cyclic program, but there is a problem when again debugging, that is exactly the function that fan loses speed governing: as long as exceed uniform temperature, fan is just with maximum rotary speed working.Careful audit program finds this is because the I/O mouth controlling fan conducting in the time of system scan temperature acquisition, conversion and display always is low level (fan is Low level effective), so the speed of fan always is maximum.Afterwards through ruminating over, and have found after having consulted related data and can show the good method that relevant information can realize temperature regulate speed in real time, namely first display section is defined as a function, then utilize this function as the delay unit exporting low and high level in PWM speed governing, so also can not the Presentation Function those skilled in the art of the present technique of influential system be understandable that
Step in the various operations discussed in the present invention, method, flow process, measure, scheme can be replaced, are changed, combined or deleted.Further, there is various operations, method, other steps in flow process, measure, the scheme discussed in the present invention also can be replaced, change, reset, decompose, combine or delete.Further, of the prior art have also can be replaced with the step in operation various disclosed in the present invention, method, flow process, measure, scheme, changed, reset, decomposed, combined or deleted, can be described as and kill two birds with one stone.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And these belong to connotation of the present invention the apparent change of extending out or variation still belong to protection scope of the present invention.
