Description
Technical field
The present invention relates to automation field more particularly to a kind of curtain state transition platforms based on wind-force detection.
Background technology
The material of window generally speaking, can be divided into three categories：Wooden, plastic-steel, aluminium alloy.Three has his own strong points.
Plastic-steel：Because being plastic material, weight is small, and heat-proof quality is good, and price is relatively low.Because often
In face of exposing to wind and rain, the sun shines, so people is most allowed to concern the anti-aging problem of plastic-steel window.In fact, the plastic-steel window of high-quality
Service life up to 100 years or so.
Aluminium alloy：Because being metal material, there is no problem of aging, and firm, impact resistance, intensity are big.But
It is exactly heat-proof quality that aluminum window, which is easiest to attacked weakness, because metal be heat good conductor, it is extraneous with it is indoor
Temperature can be transferred with the frame of window.
But it is worth query, the ratio on a fan window shared by frame is simultaneously not very big, and window is not one block of metal
Plate, but the glass of frame is inlayed, the heat transferred by frame edge strip actually can be to there is the generation of the indoor temperature of warmer, air-conditioning
Great influence
But that precautions averts perils is good, this problem, employs " bridge cut-off " skill on the aluminium alloy window having in order to prevent
Art adds one layer of resin material that is, in aluminum alloy window frame, has thoroughly broken off the approach of heat conduction.
It is wooden：Comparatively, wooden should be forms frame material the most perfect, no matter from heat-insulated, sound insulation angularly
For have apparent advantage, and inherent texture and natural figure are more moving.It is actual although wooden
On some be used to doing the solid wood of window frame and have already been through processing special layer by layer, not only without moisture, it is desirable that it is higher even
Fat is sucked, so, so-called wooden actually as fossil, solid wood after treatment is only protected
The appearance of timber has been stayed, quality is but completely different, will not cracking deformation, less suffers insect bite with worry, is corroded, moreover,
Intensity also greatly increases.
In addition, also a kind of frame structure is referred to as aluminium Bao Mu, the outdoor part of wood frame is one layer of aluminium alloy structure,
In fact, this be combine wood frame thermal insulation it is good and the advantages of intensity of aluminum alloy is high, integrate, maximize favourable factors and minimize unfavourable ones.
The wooden unique shortcoming of window is exactly that cost is too high.
The selection to the material of window and structurally is excessively paid close attention in the prior art, and for the mating curtain opening of window
Control concern is less, especially to external wind speed it is excessive or in the case of passing through there are human body curtain this how to act shortage and grind
Study carefully.

It is the two-dimentional sleiding form with certain structure into the medium filtering pattern in type medium filtering equipment, by pixel in plate according to pixel
The size of value is ranked up, and generates the 2-D data sequence of monotone increasing or decline.
2. the curtain state transition platform as described in claim 1 based on wind-force detection, it is characterised in that：
Output of the embedded processing equipment based on the wind-force detection device sends control letter to the motor driving apparatus
Number include：When the wind speed for receiving the wind-force detection device output crosses fast signal, send and receive to the motor driving apparatus
Play control signal.
3. the curtain state transition platform as claimed in claim 2 based on wind-force detection, it is characterised in that：
Output of the embedded processing equipment based on the wind-force detection device sends control letter to the motor driving apparatus
It number further includes：When receiving the wind speed normal signal of the wind-force detection device output, sent to the motor driving apparatus
Open control signal.
4. the curtain state transition platform as claimed in claim 3 based on wind-force detection, it is characterised in that：
When the shape of benchmark subregion is square, the size of each benchmark subregion is 3 × 3,5 × 5 or 7 × 7, works as benchmark
When the shape of subregion is circular, the radius of each benchmark subregion is 3 pixels, 5 pixels or 7 pixels, when benchmark subregion
Shape for it is linear when, each benchmark subregion be an one-dimensional pixel set.
