Description
Technical field
The present invention relates to safety-security area, particularly relate to a kind of intelligent household security system.
Background technology
In the driving process of driver vehicle or steamer, if weather is fine day, inevitably by sunlight
The interference irradiated.Usually, good in order to ensure the visual field of driver, steering position by being not provided with the sun-shading equipment fixed,
So, under strong illumination, easily following problem is brought to driver.
If sunlight is too strong, and manual shield plate cannot cover the sunlight irradiation area to driver, then easily give and drive
Member causes unsighted situation to occur in the process of moving, and so, once driver has judged front end traffic conditions by accident, or misses
Sentence the traveling spacing of surrounding vehicles, be easily caused vehicle accident and occur, cause to driver, passenger and the vehicles
Certain personal injury and property loss.
Under sunlight irradiates, the skin of driver is the most tanned, may cause decortication, driven meanwhile under serious conditions
The route of the person of sailing brings uncomfortable driving experience, this point, is that the manufacturer of the vehicles is unwilling to see.
The steering position being additionally, since driver place is typically in the front end of the vehicles, and at other passengers
Seating position be typically in the rear end of the vehicles, therefore, the sunlight irradiated area that driver is born is greater than typically to be taken advantage of
The sunlight irradiated area that visitor is born, and, the sunlight exposure rate that driver is born is greater than what general passenger was born
Sunlight exposure rate.As can be seen here, in the decision-making blocked for sunlight, the selection with general passenger that selects of driver is to deposit
In the probability conflicted.
But, in prior art, the sunlight mechanism of blocking for driver is generally only and is simply to set a sunshading board,
By driver in the case of sunlight strength is too high, manually selecting and push sunshading board and protect, this mode is the most backward.With

Method allowing for driver and the demand of other passengers, such as, when sunlight is too strong, may strengthen air-conditioner temperature and the wind of the vehicles
Amount, thus cause driver to obtain comfortable and that other passenger's body-sensing are the coolest situation and occur.
In order to overcome above-mentioned deficiency, the present invention has built a kind of intelligent household security system, improves existing electronics sunshade
Mechanism, by detecting the sunlight strength of steering position and sunlight scope, by association vehicle travels side
To determine sunshade strategy, the most key, the sunshade strategy determined customizes for driver, fully takes into account driver
With the different sun-shading requirements of other passengers, thus all personnel for riding public transportation means provides more preferable Consumer's Experience.
