The sweat is extracted sub- equipment and is connected with the sub- equipment of the human body segmentation and the static memory respectively, from human body Extract in image and meet each sweat subimage of sweat form, the pixel summation added up in each sweat subimage, when obtaining Pixel summation be more than presetted pixel amount threshold when, judge human body exist sweat and export there is sweat signal, when what is obtained When pixel summation is less than or equal to presetted pixel amount threshold, judge that human body does not have sweat and output does not have sweat signal.
The embedded processing equipment and the thermal infrared imager, the Visible Light Camera, the room brilliancy sensor, The outdoor wind speed detector, the static memory, described image processing equipment and the window opener connect respectively, When the ambient brightness for receiving is less than or equal to luminance threshold, opens the thermal infrared imager and close the Visible Light Camera, 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 Also there is sweat signal receiving in embedded processing equipment, determine the window opener according to the real-time wind speed for receiving Unlatching strategy.
Wherein, in described image processing equipment, using infrared image, as before detection image, infrared image is carried out can See that light formula image is changed, using the image after conversion as detection image;The unlatching strategy tool that the embedded processing equipment determines Body includes:The embedded processing equipment controls the window opener so that the window opener control window Aperture is inversely proportional to real-time wind speed;The static memory has prestored wind speed aperture synopsis, the wind speed aperture control Table gives the mapping relations of each wind speed range and window aperture, and the embedded processing equipment is according to the wind speed aperture Synopsis causes the aperture of the window opener control window to be inversely proportional to real-time wind speed.
Alternatively, in the control system:Described image processing equipment, the thermal infrared imager and the visible ray phase Machine is integrated on one piece of surface-mounted integrated circuit;The sub- equipment of described image pretreatment, the threshold value select sub- equipment, the human body point Cut sub- equipment and the sweat and extract sub- equipment and the fpga chip of different model is respectively adopted to realize;Described image pretreatment Equipment, the threshold value select sub- equipment, the sub- equipment of the human body segmentation and the sweat to extract sub- equipment and are integrated in same 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 Any simple modification made for any of the above embodiments, equivalent variations and modification, still fall within the scope of technical solution of the present invention protection It is interior.
