基于ZigBee的夜起自动照明系统

Automatic Lighting System Based on ZigBee Night

基于国内没有这种智能照明系统来改善独居老人的生活,设计这种智能照明系统,通过床两边地毯上安装的压力传感器实时监测有没有人踩在上面,当有压力时,同时判断光敏传感器所采集到的光照值,如果是有光照值(白天或者有灯亮),则不做任何处理;如果是判断是夜晚,则立刻通过ZigBee无线通信向卧室、洗手间的节点发送开灯命令,自动打开卧室、洗手间的灯。当上完洗手间回床上睡觉后,洗手间的ZigBee节点会通过红外传感器监测有没有人,如果长时间监测不到人,则自动关灯,同时通过ZigBee发送消息到卧室,卧室灯也自动关闭。

based on the domestic no this kind of intelligent lighting system to improve the lives of old people who live alone,the intelligent lighting system design,through the pressure sensor real-time monitor of the bed on both sides of the carpet installation does anyone on the above,when there was pressure,at the same time light collected by the value judgment photosensitive sensor,if there is a light value(or lights) during the day,do not do any processing;If it is a judgment is night immediately by ZigBee wireless communication to the bedroom,the bathroom node sends the lights command,automatically open the bedroom,the bathroom light.When back to bed after he go to the bathroom,bathroom Zig Bee node through infrared sensors to monitor anyone,if less than one for a long time monitoring,automatically turn off the lights,at the same time through the Zig Bee sends a message to the bedroom,the bedroom lights also automatically shut off.
