Side windowing and two kinds of outstanding window can be divided into according to the position of hinge.Side open a window horizontal direction open, sash in opening process always
Keep balance, it is not necessary to worry that autonomous travel causes danger under the influence of gravity, is generally used for the biggish main window of area；Outstanding window due to
It is vertically oriented unlatching, opening angle is restricted, the ventilation for being generally used for kitchen, defending room etc..Newer is opened flat
Window can have both both side windowing and outstanding window, allow bidirectional opening.
Sliding window, using tracks travel of the sash on window frame equipped with pulley, the advantages of this window, is no matter window is being opened
It does not take up extra space, constructs relatively simple under off status yet.But thus bring is the disadvantage is that at most there was only 50% window
Fan can be opened, poor air-tightness when closing.Multiple sash can be pushed into side folding by the improved push-pull window employed new technology
It is folded.It is also improved the sliding window of air-tightness simultaneously, but is still unable to reach the thermal property of casement window on the whole.
There are many structural forms of window, however the breakages such as crack once occurs, not only influences appearance, but also meeting
Reduce the various performances of window.Therefore, window crack situation need keep pay close attention at any time, if by the way of artificial into
Row, is time-consuming and laborious and unpractical.
The present invention built it is a kind of based on wireless communication from maintenance management method, this method includes using window from safeguarding
Management system obtains high-precision image, and further accurately analyzes the breakage in image.The window safeguards pipe certainly
Reason system is by the way of electronic maintenance, for solving the problems, such as that window crack is difficult to monitor in real time.
