教室照明区域化智能控制器的设计

Design of Intelligent Controller in Classroom Lighting System Regionalization

根据现有教室灯具的安装特点,以每排灯为单元,将教室照明区域化。每个区内用热释电红外传感器和光敏电阻来检测人体信息和灯光信息。在有人的情况下,根据灯光的强弱来控制该区内打开灯具的数目,从而达到节能降耗的目的。系统以单片机为核心,设有RS-485总线接口,并选用上位机实现各教室照明系统的网络化监控。

To make the each row of light as a unit,according to the features of the classroom lights,the classroom lighting area is devided into several units. In each area,pyroelectric infrared sensor and photoresistance were used to measure the information of body and light.The number of lighting lamp was controlled by the intensity of light in order to save energy if someone was in this area.The single chip computer with RS-485 bus interface is the core of the classroom lighting system,and the system used host computer to realize the network monitor of classroom lighting system.
