Description
Technical field
The present invention relates to a kind of intelligent bedroom system based on Internet of Things.
Background technology
Intelligent domestic system mainly develops towards the direction for personal home services, can bedroom be also to learn for student
Raw family, the place of rely study and relax, but the structure in bedroom and environment still have very with ordinary individual family
Big difference, bedroom Existential Space is narrow and small, room air exchange have some setbacks, it is circuit aging be difficult to optimize and at closing time it is indoor not
The problems such as completely enclosed.To improve student life environment, facilitate school control, difference is gone out according to the present situation in bedroom and Demand Design
It is just particularly necessary in the intelligent bedroom system of general intelligence house system.
Intelligent bedroom system is like an all-round house keeper of student dormitory, and the moment is all managing dormitory without tired
It is exhausted.Student, which has a class to open the door when returning to bedroom, no longer needs the cumbersome ground moment with key, but can pass through a card of school
Logical identification of swiping the card is opened the door.System such as detects bedroom humiture by every life data of a large amount of sensor senses bedrooms environment,
IAQ is analyzed, and optimal value is compared, and so as to which regulation makes bedroom ventilated in time, without peculiar smell, is kept most
Comfortable state.Student learns or during rest in the bedroom, can by the electrical equipment of Voice command indoor lamp, water dispenser etc
Allow them to feel very satisfied, sensation is constrained caused by the narrow space of bedroom so as to mitigate.Each school requires that student exists
Bedroom safety utilization of electric power, because change bedroom circuit over time just becomes aging, if overburden is easy to safe thing occur
Therefore intelligent bedroom system need the moment monitor bedroom circuit conditions, when detect bedroom member using it is high-power when need to cut in time
Power-off source so as to avoid occur contingency.Sometimes student at school, if giving the clothes an airing problem intelligence caused by Changes in weather
Energy bedroom system can also solve undoubtedly allow student's release trouble and worry attentively to be attended class for it.Just in case there is security situation
When, preferred plan can be used in time, as it can be found that alarm after the condition of a fire, notifies bedroom member so as to lose after discovery theft
Minimize.
Such a intelligence is provided for student, comfortable, safety living environment will make Students ' Learning more feel at ease with life.
For school, intelligent bedroom system also can help school preferably to solve management bedroom, prevent all kinds of security incidents etc.
Problem, thus intelligent bedroom system help improve student life environment and school control etc. tool be very helpful and anticipate
Justice.

Operation principle explanation：
Using stable reference power supply as reference voltage, using R1, R2, R5 partial pressures obtain the voltage equal with FB, so as to
Remove to adjust DCDC IC inside PWM by FB to control the size of output current.For example, working as output current becomes big, in sampling electricity
Voltage on resistance R5 will raise, and because VRFE+ is fixed value, so as to be that FB voltages become big, FB becomes big, and dutycycle will subtract
It is few, so as to be that output current is reduced, and a complete feedback is completed, reach the purpose of stabling current output.
Constant current calculates：
If voltage caused by the overcurrent of R5 upstream is VIo, output current Io
Reference voltage is VREF+=2.5V,
FB voltages are VFB=0.6V,
R5=0.1 Ω, R1=40K Ω, R2=10K Ω
Then：
VIo=Io*R5
VFB=VIo+ ((VREF+-VIo) * R2/ (R1+R2))
Calculate：
Io=(VFB* (R1+R2)-R2*VREF+)/R1*R5
The equation if K=(VFB* (R1+R2)-R2*VREF+)/R1 is taken
Io=K/R5
In terms of calculation formula, Io output currents and output voltage and input voltage do not have any relation, only with VFB. R1,
R2, VREF are relevant, and these parameters are in specific design, they be all it is fixed (VFB be in stable state it is fixed, for
Chip fp7192 constant pressure chips, its steady-state value are 0.6v), so K is necessarily a fixed value, so formula：
Io=K/R5 has the fabulous linearity, and has excellent controllability.
Parameter above being assigned the occurrence being set above can obtain：
Io=(VFB* (R1+R2)-R2*VREF+)/R1*R5
=(0.6* (40+10) -10*2.5)/40*0.1
=1.25A
It can be seen that, this scheme introduces fixed VREF+ in equation more than, is only taken so that Io becomes one with R5
The linear equation of sample resistance, makes Io become constant, so as to reach the purpose of constant current.
The characteristics of constant-current circuit in this programme, is as follows：
