Description
Technical field
The present invention relates to image processing field, more particularly to a kind of vehicle window multifunction control system.
Background technology
Glazing material is based on glass.Early in before more than 80 years, glass has been mounted on the T-shaped car that Ford factory of the U.S. produces, when
When be the front end that compartment is mounted in plate glass, motorist is exempted the hardship exposed to wind and rain.Between decades from now on, glass
Industry progressively sets foot in auto industry, creates the kinds such as a variety of safety glass-laminated glass, safety glass and local toughened glass,
Significantly improve the performance of vehicle glass.
Wherein laminated glass refer to one kind it is transparent can cohesive plastic foil be attached between two layers or triplex glass, by plastics
Obdurability and the rockiness of glass be combined together, add the resistant to breakage ability of glass.Safety glass refers to common glass
Glass quenching makes interior tissue form certain internal stress, so that the intensity of glass is strengthened, when by impact grinding, glass
Glass can split into the fine grained chippings with root face, and occupant is difficult to damage.And local toughened glass is a kind of new of safety glass
Kind, it passes through specially treated, can be when by concussion fracture, and the crackle of its glass can still keep certain definition,
Ensure that the area of visual field of driver is unaffected.Current shield glass is with interlayer safety glass and sandwiched area tempering glass
Based on glass, stronger impulsive force can be born.
The development of Modern Car external form and the development of glass technology are closely bound up.Early in before more than 40 years, car front windshield glass
Glass bends windshield using single-piece, and has gradually abandoned the windshield of plane.The car windshield of today
The general large curved surface type for all doing integral width formula, there is certain radian up and down.No matter this bend glass is from processing
Process is still a kind of technical requirements very high product from the point of view of the cooperation of assembly, all because it be related to vehicle, intensity,
The problems such as heat-insulated, assembling.
Car windshield uses bend glass, first from aerodynamic angle.Because Modern Car is just
Above 100 kilometers greatly of normal speed per hour, windstream, which flows through bend glass, can reduce vortex and turbulent flow, so as to reduce air drag.
Seamlessly transitted plus window frame edge and bodywork surface, glass is naturally as a whole with vehicle body, visually both felt overall coordination
With it is attractive in appearance, the air resistance coefficient of vehicle can be reduced again.In addition, bend glass has higher intensity, relatively thin glass can be used
Glass, there is certain meaning to car lightweight.
The wraparound windscreen of Modern Car will accomplish that the flatness of bent corner will height, it is impossible to optically abnormal occur
Become, it is indeformable dazzle-free from the object outside any angle viewing on driver's seat.Car glasses were generally used neatly in the past
Band is modified or protected along glass edge, and the glass on present car all uses ceramic glaze, i.e., so-called " black surround frame ".There are many sedan-chairs
Car windshield also plated film, using reflectance coating technique or the composition of improvement glass, only allows sun visible ray to enter in compartment, gear
Firmly ultraviolet and infrared ray, largely alleviate the hardship for the sweltering heat that occupant is subject to.It is this to be referred to as showing for " green glass "
For car glasses, it is widely used.
The security performance of windshield is very important.If just not saying security performance it is low it to occupant's
Degree of danger, be exactly to automobile in itself, just look like that face is marred by a scar, etc. one if substantially sheltering a little occurs crackle or had in windshield
Sample, the image appearance of serious infringement vehicle.Therefore, the security requirement of windshield is very high.
Vehicle window shield with one of the matching used equipment of vehicle window, can be played in vehicle travel process becalm, rain-proof,
It is ventilated and other effects, moreover it is possible to effectively to remove human pilot and the degree tired out of occupant.But, it is of the prior art to hide
Plate is integrally fixed above vehicle window, it is impossible to flexibly determine whether start shield and can not adjust automatically shield unlatching amplitude.
The content of the invention
In order to solve the above problems, the invention provides a kind of vehicle window multifunction control system, in-car human body can be detected
The irritated degree of human body in image, and when the irritated degree corresponding grade of human body is more than or equal to predetermined level threshold value, send agitation
Alarm signal, and exported the irritated degree corresponding grade of human body as the irritated grade of target, more it is essential that the shield control
Control equipment determines the falling head bag of shield based on the irritated grade of the real-time rainfall, the real-time wind speed and the target

In addition, time division duplex is a kind of duplex mode of communication system, receive in mobile communication system for separating and
Transmit channel.Mobile communication positive third generation development at present, China have submitted 3G (Third Generation) Moblie standard grass in June, 1997
Case (TD-SCDMA), the characteristic such as its tdd mode and smart antenna new technology is greatly prized by and into three main candidate standards
One of.Fdd mode rules all the land in the first generation and second generation mobile communication system, and tdd mode does not draw attention.But due to
With many advantages of the development of new technology, and tdd mode the need for new business, tdd mode will be increasingly subject to pay attention to.
The operation principle of time division duplex is as follows：TDD is a kind of duplex mode of communication system, is used in mobile communication system
Received and transmission channel (or uplink downlink) in separation.Received in the GSM of tdd mode and transmission is same
Frequency channels are the different time-gap of carrier wave, and reception and transmission channel are separated with the time is ensured；And the mobile communication system of fdd mode
The reception and transmission of system are that on two symmetrical frequency channels of separation, reception and transmission channel are separated with frequency range is ensured.
It is different using the GSM feature and communication benefit of different dual-modes.The movement of tdd mode is led to
Up-downgoing channel is with same frequency in letter system, thus the reciprocity with up-downgoing channel, and this leads to the movement of tdd mode
Letter system brings many advantages.
In tdd mode, the transmission of information can be carried out in same carrier frequency in up-link and downlink, i.e.,
The transmission of information is realized on same carrier wave by the time-division in the transmission of information and downlink in up-link.
