基于STC单片机多传感器的智能窗设计

Base on STC single-chip microcomputer and more multi-sensor intelligent window design

目前人们家居生活中使用的窗户主要采用人工开关的方式,而随着智能化家居的概念逐渐被实现,如何寻求一种集安全、实用、人性化于一体的智能型新型窗户成为人们关注的热点之一。本设计以STC89C52RC单片机为控制核心,主要通过红外传感器来检测环境中是否有物体闯入并报警,烟雾传感器来检测室内有害气体的浓度并采取相应安全措施,温湿度传感器来检测环境中温湿度的高低,最终通过步进电机来实现窗户的自动开启和关闭,实现智能化的基本要求。系统中所采用电路元器件都比较实用可靠,因而具备电路简单,成本低,维护方便等特点。

Recently ,the home furnished windows are mainly manipulated by manual control. To find out a new kind of smart window characteristic of safety, practical and humanized intelligent has been a hot topic concerned all around. In this paper, STC89C52RC microcomputer is selected as control unit. If there is an unknown object breaking into the environmental detected, infrared sensor will alarm. If harmful gas is detected, smoke sensor will start safety measure. Furthermore, temperature and humidity sensor decorated on the smart window is utilized to detect the temperature and humidity all around. With the combination work of those sensor instructed above, stepper motor is automatic controlled to manipulate the window, thus meeting the basic demand of smart design. The components of the circuit in the control system is reliable and inexpensive, so it is convenient to maintain.
