In fpga chip；The control system can also include：Display device, is connected with the embedded processing equipment, for receiving
And show the ambient brightness and the real-time wind speed.
In addition, FPGA (Field-Programmable Gate Array), i.e. field programmable gate array, he be
The product further developed on the basis of the programming devices such as PAL, GAL, CPLD.He is led as special IC (ASIC)
A kind of semi-custom circuit in domain and occur, both solved the deficiency of custom circuit, overcome original programming device door again
The limited shortcoming of circuit number.
With the circuit design completed by hardware description language (Verilog or VHDL), can be through simple synthesis and cloth
Office, is quickly burned onto on FPGA and is tested, and is the technology main flow of modern IC designs checking.These editable elements can be by
For realize some basic logic gates (such as AND, OR, XOR, NOT) or more more complicated combination function such as
Decoder or mathematical equation.Inside most FPGA, also for example touch comprising memory cell in these editable elements
Send out device (Flip-flop) or other more complete block of memory.System designer can be as desired by editable company
Connect the logical block inside FPGA to couple together, just look like that a breadboard has been placed in a chip.One dispatches from the factory
The logical block of finished product FPGA afterwards and connection can change according to designer, so the logic work(required for FPGA can be completed
Energy.
FPGA is in general slow than the speed of ASIC (special IC), realizes same function than ASIC circuit face
Product is big.But they also have the advantages that it is many such as can quick finished product, the mistake that can be modified in correction program and
Less expensive cost.Manufacturer is likely to the FPGA of the still edit capability difference that can provide cheap.Because these chips have poor
Editable ability, so these design exploitations be to complete on common FPGA, design is transferred to into a class then
It is similar on the chip of ASIC.Another method is with CPLD (Complex Programmable Logic Device, complexity
PLD).The exploitation of FPGA is very different relative to the exploitation of traditional PC, single-chip microcomputer.FPGA is with concurrent operation
Based on, realized with hardware description language；Compared to PC or single-chip microcomputer (either von Neumann structure or Harvard structure)
Order operation has very big difference.
Early in 1980 mid-nineties 90s, FPGA is taken root in PLD equipment.CPLD and FPGA include some relatively large numbers
The Programmadle logic unit of amount.The density of CPLD gates is between thousand of to tens of thousands of logical blocks, and FPGA typically exists
It is tens of thousands of to millions of.The main distinction of CPLD and FPGA is their system structure.CPLD is a somewhat restricted structure.
This structure is arranged the depositor with the locking of some relatively small amounts by the logical groups of one or more editable result sum
Composition.Such result is a lack of editing motility, but but have it is anticipated that time delay and logical block it is single to connection
The advantage of first height ratio.And FPGA is that have many connection units, although so allowing him more flexibly can edit,
Structure is complicated more.
Using the bedroom window intellectuality opening control system of the present invention, for bedroom personnel in prior art in sleep shape
Window uncontrollable technical problem during state, introduces luminance sensor and air velocity transducer and using adaptivenon-uniform sampling threshold value
Image processing equipment, realizes carrying out bedroom window according to outdoor wind speed and indoor occupant degree of sweating when bedroom personnel sleep soundly
Intelligent open control.
Although it is understood that the present invention is disclosed as above with preferred embodiment, but above-described embodiment being not used to
Limit the present invention.For any those of ordinary skill in the art, under without departing from technical solution of the present invention ambit,
Many possible variations and modification are made to technical solution of the present invention using the technology contents of the disclosure above all, or are revised as
With the Equivalent embodiments of change.Therefore, every content without departing from technical solution of the present invention, according to the technical spirit pair of the present invention

Image；The threshold value selects sub- equipment to be connected with the static memory and the sub- equipment of described image pretreatment respectively, for according to
It is secondary to select a value from the human body gray threshold scope as pre-selection gray threshold, using pre-selection gray threshold by gray processing
Image division is pre-selection background area and pre-selected target region, calculates the area ratio that pre-selection background area occupies gray level image
As background area ratio, the pixel average gray value of pre-selection background area is calculated as background average gray value, calculate pre-selection mesh
Mark region occupies the area ratio of gray level image as target area ratio, calculates the pixel average gray value in pre-selected target region
As target average gray value, background average gray value is deducted into the grand mean gray value of gray level image, the difference of acquisition it is flat
Background area ratio is multiplied by obtain the first product in side, and target average gray value is deducted the grand mean gray value of gray level image,
The difference of acquisition square is multiplied by target area ratio to obtain the second product, by first the second product addition of sum of products obtaining and
Value, selects and is worth maximum pre-selection gray threshold as target gray threshold value；The sub- equipment of the human body segmentation is selected with the threshold value
Sub- equipment connection is selected, for gray level image is divided into background image and human body image using target gray threshold value；The antiperspirant
The sub- equipment of water extraction is connected respectively with the sub- equipment of the human body segmentation and the static memory, extracts and meet from human body image
Each sweat subimage of sweat form, the pixel summation added up in each sweat subimage, when the pixel summation for obtaining is more than
During presetted pixel amount threshold, judge human body exist sweat and output there is sweat signal, when the pixel summation for obtaining less than etc.
When presetted pixel amount threshold, judge that human body does not have sweat and output does not have sweat signal；
It is the embedded processing equipment and the thermal infrared imager, the Visible Light Camera, the room brilliancy sensor, described
Outdoor wind speed detector, the static memory, described image processing equipment and the window opener connect respectively, when connecing
When the ambient brightness for receiving is less than or equal to luminance threshold, opens the thermal infrared imager and simultaneously close the Visible Light Camera, when connecing
When the ambient brightness for receiving is more than luminance threshold, closes the thermal infrared imager and open the Visible Light Camera；It is described embedded
Also there is sweat signal receiving in formula processing equipment, determine opening for the window opener according to the real-time wind speed for receiving
Open strategy；
Wherein, in described image processing equipment, infrared image is carried out into visible ray using infrared image as before detection image
Formula image is changed, using the image after conversion as detection image；
Wherein, the unlatching strategy that the embedded processing equipment determines is specifically included：The embedded processing equipment control is described
Window opener so that the aperture of the window opener control window is inversely proportional to real-time wind speed；
Wherein, the static memory has prestored wind speed aperture synopsis, and the wind speed aperture synopsis gives each
The mapping relations of individual wind speed range and window aperture, the embedded processing equipment cause institute according to the wind speed aperture synopsis
The aperture for stating window opener control window is inversely proportional to real-time wind speed.
