移动互联网框架下的室内环境控制系统设计

Design of indoor environment control system based on mobile internet

针对当前环境污染严重以及现有智能家居系统的不足,研制了一种基于移动互联网的室内环境控制系统。以单片机为核心设计多参数测控终端,采用树莓派开发室内控制中心,以智能手机作为用户终端,融合ZigBee和Wi-Fi技术进行无线通信。通过对室内温度、湿度、光照和甲醛含量的全面检测,以及对空调、风扇、加湿器、照明灯、窗帘、负离子发生器等多种家电和设施的控制,实现室内环境参数自动、便捷调控。经过长达1000小时的无故障运行测试,并对居室环境中甲醛浓度与温湿度的关系进行定性分析,表明该系统操作简单、实时可靠,满足高品质生活需求,具有较高的实用价值。

In view of the current serious environmental pollution and the shortage of the existing smart home system, an indoor environment control system based on mobile internet is developed. The system is composed of several modules,which include single-chip microcomputer based multi parameter detection ＆ control terminal, raspberry pie based indoor control center, intelligent mobile phone based user terminal, combining and ZigBee and Wi-Fi being used for wireless communication. Through a comprehensive inspection of the indoor temperature, humidity, illumination and formaldehyde content, and control of home appliances and facilities such as air conditioner, fan, humidifier, lights, curtains, negative ion generator, the indoor environment parameters can be regulated automatically and conveniently. After running without fault test in 1 000 hours, and studying the relationship between formaldehyde concentration and temperature ＆ humidity, it shows that the system has the advantages of simple operation, reliable and real-time, which can meet the demand of high quality of life, and has a high practical value.
