Specific embodiment
The embodiment to the adaptive-filtering selection system based on graphical analysis of the invention is entered below with reference to accompanying drawings
Row is described in detail.
The shutter in modern age is invented by American, is made John Han Consulting inferior and is achieved this within 21st in August in 1841
Patent of invention.
Shutter is typically relatively wide, is generally used for indoor and outdoor sunshade, ventilation.The louver curtain wall of more and more people's approvals
It is also to be evolved from shutter.Louver curtain wall functional advantage is more, and very attractive in appearance, is generally used for high-rise building.
Shutter has following effect：
1st, energy-conservation attractive in appearance, succinct agile, shutter can be packed up completely, and scenery covers all at one glance outside window, the brief generous windows of window
Curtain then occupies the segment space of window so that the width of the vision window in house is affected, it appears cumbersome.
2nd, privacy is protected, extraneous sight line is stopped with the concave and convex direction of blade, while daylighting, blocked from top to bottom
At extraneous sight line night, the convex surface of blade is to interior, and shadow will not reflect and show outdoor, totally trust, easy to clean, usually only
Need to be wiped with rag, neutral lotion during cleaning, it is not necessary to which worry is faded, discoloration water proof type shutter can also water completely
Wash.
3rd, it is cool in summer and warm in winter, well-insulated material is employed, indoor temperature is effectively kept, reach the mesh of save energy
, simple free angle adjustment, control injects light, controls to inject light to adjust blade angle, can arbitrarily adjust leaf
Piece is to the position being best suitable for.
4th, shielding of ultraviolet, shutter effectively shielding of ultraviolet can be injected, and protect the furniture not influenceed by ultraviolet
And fade, shutter compared with curtain, shutter that can have the function that curtain is short of with the blade of flexible modulation.In sunshade
Aspect, shutter is in addition to it can keep out ultraviolet radiation, moreover it is possible to adjust indoor light；In terms of ventilation, shutter is fixed
The installation of formula and abundant quality, can pleasantly enjoy breezy cool breeze and be worried without other；The Dutch roll of curtain can be indoor
Life is flickering, and the design of shutter superimposition formula layer by layer then ensure that the privacy of household；Additionally, when shutter is completely enclosed
As many fan windows, sound-insulating and heat-insulating can be played a part of.
Currently, the control program to the forms including shutter is still partial to manual type, i.e. people according to the body-sensing of itself
Go oneself be controlled the open mode of forms, for example, the ventilation that just opened a window when people feel vexed, when people feel
To indoor environment brightness well below outdoor environment brightness when with regard to manual window opening, when people feel outdoor temperature is high when just manually
Window is closed, this manual method efficiency is too low and precision is not high.
Meanwhile, existing forms open effective joint-action mechanism of control program shortage and other electronic equipments, it is impossible to maximum
Requirement of the people to environment is met to degree, in addition, existing forms open control program lacks some necessary parameter detectings
Equipment, causes some demands of people to be difficult to be met by the control of forms.
In order to overcome above-mentioned deficiency, the present invention has built a kind of adaptive-filtering selection system based on graphical analysis, right
Existing window structure is optimized, and increases necessary parameter detection equipment, is enriched and is improved existing forms controlling mechanism, from
And improve the precision and efficiency of forms control.

In addition, the abbreviation of general packet radio service technology (General Packet Radio Service), he is GSM
A kind of available mobile data services of mobile phone user.GPRS can say be GSM continuity.GPRS is passed with the past continuous in channel
Defeated mode is different, is transmitted with package (Packet) formula, therefore the expense that user is born is with its data transmission list
Position calculates, and non-usage its whole channel, in theory inexpensively.The transmission rate of GPRS can be promoted to 56 even 114Kbps.
GPRS is often described as " 2.5G ", that is to say, that this technology is located at the second generation (2G) and the third generation (3G) is mobile
Between mechanics of communication.He is by using untapped TDMA channels in GSM network, there is provided the data transfer of middling speed.GPRS breaks through
GSM nets can only provide the mode of thinking of circuit switching, only by increasing corresponding functional entity and to existing base station system
Carry out part transformation to realize packet switch, the input of this transformation is comparatively and little, but the user data rate for obtaining
It is considerable.And, because the intermediary's converter required for no longer needing existing wireless application, connection and transmission all can
It is more convenient easy.In this way, user can both connect to the internet, the interactive communications such as video conference are participated in, and in same video signal net
The user of (VRN) on network, it might even be possible to without by dialling up on the telephone, and continue and network connection.
In the communication mode of packet switch, data are divided into the bag of certain length to the communication mode of GPRS packet switches
(packet), has a packets headers before each bag (address mark therein indicates that the packet is sent to where).Data transmit it
It is preceding and channel need not be allocated in advance, set up connection.But when each packet is reached, the information in datagram header
(such as destination address), finds an available channel resource and sends the datagram temporarily.In this load mode, number
According to the side's of sending and receiving cochannel between there is no the occupancy relation of fixation, channel resource can be regarded as being total to by all of user
Enjoy and using.A kind of paroxysmal business characteristic is all shown in most cases due to data service, to channel width
Changes in demand is larger, thus using packet mode carry out data transmission be possible to better profit from channel resource.Such as one is entered
The user that row WWW is browsed, the most of the time is in browse state, and the time for being really used for data transmission only accounts for very little ratio.
In this case according to the mode of fixed busy channel, it will cause the larger wasting of resources.
System is selected using the adaptive-filtering based on graphical analysis of the invention, for the existing forms control of prior art
There is the technical problem of latent defect in system, internal structure transformation is carried out by existing forms, increase some controlled parts
It is controlled in order to forms, enriched by existing parameter detection equipment, correspondingly, existing forms control model is entered
Row is improved to improve the automaticity and multifunctionality of forms control.
Although it is understood that the present invention is disclosed as above with preferred embodiment, but above-described embodiment and being not used to
Limit the present invention.For any those of ordinary skill in the art, in the case where technical solution of the present invention ambit is not departed from,
Many possible variations and modification are all made to technical solution of the present invention using the technology contents of the disclosure above, or is revised as
With the Equivalent embodiments of change.Therefore, every content without departing from technical solution of the present invention, according to technical spirit pair of the invention
