【摘要】：目前,国外的智能家居系统,功能已经相对完善,但是价格昂贵,不适合国内普通大众消费。国内各个厂家的智能家居系统又各自为政,缺乏统一的行业标准。这些因素严重阻碍了智能家居的发展。所以,目前急需一个低成本、低功耗、标准化的智能家居系统。本文提出了一个基于ARM和ZigBee技术智能家居系统的设计方法,该系统在Ubuntu下使用Qt技术开发,采用C++语言编写代码。首先,设计了智能家居系统的总体结构,系统拓扑结构将该系统规划为前端的ZigBee无线传感网和后端的ARM网关两部分,系统软件结构规划了系统的功能模块和工作流程。其次,设计实现了安防报警模块,该模块利用烟雾传感器检测烟雾浓度,若浓度超过阈值,则触发报警;利用霍尔传感器检测门窗是否被非法打开,若被非法打开,则触发报警。然后,设计实现了照明系统模块,该模块利用热释红外传感器检测附近是否有人,有人开灯,无人关灯;利用光敏传感器检测光线的明暗变化,若光线变暗,则打开电灯,关闭窗帘,若光线变亮,则关闭电灯,打开窗帘。最后,设计实现了温湿度管理模块,该模块利用温湿度传感器检测温度和湿度,若温度较高,则打开空调,若湿度较低,则打开加湿器,否则关闭设备。本文最终为中低端用户提供一套经济型智能家居系统,实现家居的自动化,提升普通用户家居生活的安全性、方便性和舒适性。
[Abstract]:At present, the foreign smart home system, the function has been relatively perfect, but the price is expensive, is not suitable for the domestic general public consumption. Lack of uniform industry standards. These factors seriously hinder the development of smart home. Therefore, there is an urgent need for a low cost, low power consumption. This paper presents a design method of intelligent home system based on ARM and ZigBee technology. The system is developed with QT technology under Ubuntu. C language is used to write code. Firstly, the overall structure of smart home system is designed. The system topology plans the system as the front-end ZigBee wireless sensor network and the back-end ARM gateway. The software structure of the system plans the function module and work flow of the system. Secondly, the security alarm module is designed and implemented. The module uses smoke sensor to detect the smoke concentration, if the concentration exceeds the threshold, the alarm is triggered. Hall sensor is used to detect whether the windows and doors are opened illegally, and if they are opened illegally, the alarm is triggered. Then, the lighting system module is designed and implemented. The module uses thermoluminescence infrared sensor to detect whether there is anyone nearby. Some people turn on the lights, no one turns off the lights; Guang Min sensor is used to detect the light and dark changes of light, if the light darkens, turn on the light, close the curtains, if the light becomes bright, turn off the lights and open the curtains. Finally, the design and implementation of the temperature and humidity management module. The module uses temperature and humidity sensor to detect temperature and humidity, if the temperature is high, open the air conditioning, if the humidity is low, open the humidifier. Otherwise, shut down the equipment. This paper finally provides a set of economical intelligent home system for the middle and low end users, realizes the home automation, enhances the security, convenience and comfort of the ordinary user's home life.
