Abstract
In this paper, AT89C51 microcontroller used in the past, small-scale integrated circuits to achieve the smart window control circuit was modified to make it more practical and intelligent.
This product developers have some inspiration. Conceptual design in a systematic way, under the guidance of an objective demand the establishment of a functional structure of a multi- Case to produce a program eva luated simultaneously as steps towards self-closing with rain, strong winds closed automatically and the time switch function The smart window design, and more quantitative assessment of the program. The conceptual design process that systematically practical Scientific. The control system through the data sensing circuit detection test in cycles and the indoor temperature, humidity, harmful gases (such as coal gas) concentration and other environmental parameters Then with the preset parameters from the control of the keyboard compared to the critical value, in order to make open / close windows, turn / stop the ventilator, reducing / heating (wet) and other judgments, recrystallization Co-window state detection circuit detects the window state, issued a series of control commands, complete the rain will automatically close windows, indoor harmful gas exceeding the auto- Window (and rotating ventilator), temperature (wet) and other control functions. It can also control the keyboard, the direct control of the window on / off, ventilation windows The turn / stop, warm (wet) of rising / falling, select the display type and other parameters.
