Embodiment 1

A kind of SCM Based curtain that can be realized intelligent automatic control, which is characterized in that including single-chip microcontroller, motor, PM2.5 sensor, ultraviolet light illumination photometer, reel spindle window curtain；PM2.5 sensor, ultraviolet light illumination photometer are connect with single-chip microcontroller respectively Connection, motor are connect by controllor for step-by-step motor with single-chip microcontroller；PM2.5 sensor, ultraviolet light illumination photometer are located at outdoor In atmospheric environment, for PM2.5 concentration and uitraviolet intensity outside atmospheric environment room outside sensing chamber；Reel spindle window curtain: in the upper of curtain End is using aluminum pipe as spool, and lower end and the fixed volume of bottom bar are together；It is mounted in one respectively in the two-port of aluminum pipe The axle bed in central band hole, wherein rotary head is elastic cylinder structure, and in the centre bore of axle bed, the shaft of motor covers rotary head fixing sleeve It in the hole of rotary head and is completely fixed, so that motor drives aluminum pipe to rotate by positive and negative rotation；Another axle bed is equipped with by centre bore Power-assisted coiler is equipped with drawing bead chain on power-assisted coiler, power-assisted coiler can be pulled to drive aluminum pipe by drawing bead chain Rotation is further such that the upper and lower scrolling of curtain；

Casement uses trilaminate stack composite construction, anti-PM2.5 layers, anti-purple for being followed successively by UV resistance photosphere, filtering PM2.5 Outer photosphere structure；

What motor was selected is 42 stepper motors suit, and wherein the model TB6600 of driver, microcontroller development board are selected Arduino UNO R3, this single-chip microcontroller are easy simple to operation, save the complexity of programming.Selecting has the ultraviolet of enlarging function Line illumination photometer, operating voltage is in 5V, and respective wavelength is in 200nm-370nm, with reliably accurate ultraviolet measurement level. What PM2.5 sensor was selected is GP2Y1014AU dust sensor, and being able to detect superfine particle minimum detection value is 0.8 milli Rice is usually used in air purifier system, while it has extremely low current drain, and service life reaches 5 years.

Robot control system(RCS) real work circuit connection is as follows, first connect single-chip microcontroller USB port with computer, can pass through computer Display screen learns outdoor PM2.5 and uitraviolet intensity data.3., 4. both threads are grounded PM2.5 sensor, and 5., 6. both threads connect Power supply VCC, 2. line is that output end is connected with 2 hole of Arduino R3 Chip Microcomputer A, for ultraviolet light illumination photometer, inside contain Sensor and amplifier installation, amplifier one end are connected for 0 mouthful with Arduino R3 Chip Microcomputer A.For under 12V operating voltage Motor group be set with working principle be controllor for step-by-step motor 7., 8. wiring hole and Arduino R3 single-chip microcontroller 7., 8. wiring hole It is connected, has A+ A- and B+ B- plug wire hole corresponding to controllor for step-by-step motor to have connected respectively in the inside of stepping motor It is good.Arduino R3 single-chip microcontroller exports PWM alternating voltage by controllor for step-by-step motor, and advantage is that the waveform of output is rectangular Wave, rectangular wave have duty ratio, i.e., the ratio that high frequency waveforms account for entire waveform can regulate and control electricity by adjusting the height of frequency The revolving speed of motivation, and then adjust the speed of shade rollerl blind shaft.

The material of antiultraviolet: polyurethane binder, with excellent anti-ultraviolet function, raw material is aliphatic isocyanide Acid esters is completely suitable for open air；Without in addition adding the surfacecti proteons such as coating, ultraviolet absorbing agent, antiultraviolet pad or film For material as other polyurethane, which shows the features such as high activity, viscosity are variable, bond strength is big.It can be effective It is impregnated with glass fibre, generates lasting high intensity.Furthermore the material also has the function of anti-graffiti and fire retardant.

Anti- PM2.5 material: general filtering material is made of non-woven cloth, realizes filtering function by the mode of fiber filter Energy.Usual fiber filter has five big mechanism: Direct Acquisition, inertial deposition, gravity sedimentation, diffusional deposition effect and Electrostatic Absorption. It has complicated three-dimensional structure first, and especially with the non-woven cloth of superfine fibre production, interfiber pore is small and is distributed Uniformly, overall porosity is high, and pulp freeness is big, therefore big with the contact area of ambient windstream, with the dust particles in air-flow The probability of contact is high, while filtration resistance is small, and dust containing capacity is high.Secondly its internal structure has ideal fiber labyrinth system, The dispersion effect that fluid can be enhanced makes the powder dust particle to be filtered have more chances to collide and be captured with single fiber, he is therefore Filter efficiency with higher.Research finds that filter efficiency corresponding to the particulate matter of 0.3 μm of partial size is minimum, therefore 0.3 μm logical It is often seen as examining the index of filter material filter efficiency.PM2.5 partial size is filtered at 2.5 μm or so, so manufacturing work using nonwoven fabric Skill can achieve dreamboat, can be bought with direct market.The effect that fluid flow rate accelerates filter course can also be improved, tool Have that the technological process of production is short, yield is high, at low cost, the characteristics of being easy to other materials compound deep processing.We are made using polypropylene It can realize that fiber is most thin for raw material with the technique of melt blown non-woven, retention delay acts on strongest effect.
