Description
Technical field
The present invention relates to intelligent door and window technical fields, specifically the intelligent door and window dress of wire form marmem driving
It sets.
Background technique
Each building requires door and window, and people realize ventilation, adjusting room temperature etc. by the opening and closing of door and window
Purpose.With intelligentized arrival, intelligent door and window is also some public places, high-grade goods room, market, is used in farm wide
General high-tech product.Door and window of today is no longer only antitheft, daylighting single material object, but embodiment and the body of a kind of culture
The symbol of part.From the point of view of the development trend of present aluminum alloy doors and windows industry, intelligent door and window is the certainty of the following door and window industry
Trend.
The main function of intelligent door and window has the following:
1. wireless remote control
Indoors any position can wireless remote control door and window (curtain) open and close and any stop.
2. automatic windproof rain-proof
It lives a life, forgets that closing window is common occurrence, whenever blowing and raining is just grieved endlessly in outside.Intelligent door and window is equipped with
Wind and rain sensor, when wind-force reaches 3 grades or rainwater is beaten on a sensor, window is voluntarily closed immediately, is eliminated and is looked back for us
Sorrow.
3. flash appeal
If meeting with bad person to enter the room, alarm signal can be sent immediately, facilitates emergency, it is also possible to old man, child's contingency at home
It calls for help and alarms with acute disease.
4. automatic prosecution combustion gas
When detecting the signals such as coal gas, pernicious gas, intelligent controller inner microcomputer issues corresponding instruction automatically, by window
Family, exhaust fan automatically turn on, and are simultaneously emitted by alert sound and alert is passed to master cellular phone and Security Department.
5. automatic prosecution fire
Once there is fire, sensor can detect smoke signal at the first time, and intelligent controller issues instruction, by door and window
It opens, is simultaneously emitted by alert sound and alert is transmitted on master cellular phone.
Above-described intelligent door and window open and close system in the prior art relies primarily on three devices: sensor, maincenter dress
It sets and driving element, and then completes on-off action.Sensor sensing transmits information to microcomputer component to the variation of ambient enviroment
It is analyzed, and then controls mechanical drive element and be adjusted.But this covering device stability is poor, any one intermediate component goes out
Existing failure, will all will lead to whole device and be unable to run.For example, going out when electric system failure will will lead to control system
Existing problem；When motor or machine failure will will lead to driving device and cannot work.
Shape-memory material be it is a kind of stimulation, response type functional material.This kind of material " can remember " the initial of oneself
Shape.Shape memory effect just refers to that material under extraneous stimulation, can change the shape of itself and reply original shape.No
The different stimulated (such as thermal and magnetic, light, chemistry) that same material can be generated according to external environment, restore the original shape of itself.
If in case of heating, replying the original shape of itself, then referred to as the shape memory effect of thermal drivers or thermotropic shape
Memory effect.And so on, it can produce the shape memory effect of mangneto, photic, chemical driving.
Marmem (SMA) is used as a kind of novel intelligent material, has obtained faster development in recent years.So-called shape
Memory effect refers to and is heated to a certain temperature to SMA material in advance, and since internal crystal structure changes, SMA will overcome modeling
Property deformation-recovery is to original form.Huge recovery stress is generated in contraction process, therefore can be as driving force application
Into driver.
Compared with conventional ADS driving mode, using Ti-Ni alloy as the marmem of representative have power/quality than it is high,
Reply the characteristics of being displaced big (8%), recovery stress big (500MPa).It can be driven due to only providing heat, the recovery stress of generation
It may be made directly on workpiece with displacement is replied, reduce intermediate transmission mechanism, therefore whole device structure is simple, no dirt
Dye, energy loss are small.SMA has sensing function, and the physical quantity (such as displacement, resistivity) by detecting its own changes, and can obtain
Know material temperature variation and respective conditions, power output and output displacement size are obtained after processing.Currently, marmem is maximum
The shortcomings that for response frequency it is low, the main reason is that temperature-fall period is slow in SMA Thermal Cycling.
The characteristics of according to memorial alloy, can make small and exquisite, increasingly automated, reliable performance component of it,
The various fields such as aerospace, electronic communication, health care, machine-building, derived energy chemical, civil construction and daily life have
Wide application space.
