【摘要】：计算机技术、通信技术及嵌入式技术的发展推动着智能家居快速发展,随着经济生活水平的提高,智能家居系统的功能随着人们生活需求不断完善和提升。本论文主要针对两点,其一是对当前智能家居家电控制系统现状分析并阅读大量相关论文著作的基础上总结得到：以往的家电控制系统采用两种方案——电源控制方案和红外控制方案。电源控制方案的优点是把家用电器电源直接切断,既省电又能避免外部电路故障等原因导致烧坏家用电器,缺点是对于像空调等需要遥控开启才能运行的家电不能实现控制,而红外控制家电的优缺点与电源控制正好相反；通过以上分析可见,两种方案可优势互补,因此本论文将两种方案整合,采用电源和红外双控制的方式灵活控制家电,弥补单个控制的不足。其二是人体体征数据监测系统的设计；一直以来,健康问题一直在生产、生活中受到重视,随着中国社会的发展,人们也越来越关注自身的健康状况和疾病隐患,脉搏、心跳等是人体的重要特征,监测这些数据有实际的意义；对居家人群特别是老人和小孩,体征监测对其十分必要；床是与人体最贴近的家居用品,且人体病变时会躺在床上休息,因此床是理想的监测平台；通过以上分析,本文以家居用品——床为监测平台设计一个获取脉搏、心跳等体征数据的体征监测系统。论文首先提出了智能家居系统方案——家庭网关和Zigbee组网方案,系统设计包括家庭网关软硬件平台搭建、家电控制软硬件设计、体征数据采集模块软硬件设计,Zigbee组网等几个部分。从整体来看,本设计中需要解决的问题有：家庭网关平台包括家庭网关处理器S3C2440A外围接口设计,Linux操作系统,Zigbee组网及传输协议,GSM模块选型及系统传输协议设计,最后移植和配置boa服务器并设计远程登录管理界面。论文着重讨论家电控制模块和体征数据采集模块的设计和实现,重点阐述软、硬件设计方法并给出系统通信协议；家电控制模块结合以往设计方案缺陷,提高可用性和拓展性,该模块可拓展应用于服务器机房等场所的空调控制；体征数据采集模块采用压电薄膜传感器,有独立的MCU,可独立进行数据分析,体征数据异常时,通过GSM通信模块向手机发送提醒信息及体征数据。通过实验测试,模块可以控制家电,获取体征数据和提醒短信等,系统实现其预期功能,达到预期设计目标。
[Abstract]:The development of computer technology, communication technology and embedded technology promote the rapid development of smart home. With the improvement of economic living standard, the function of smart home system is improved with people's living needs. This paper mainly aims at two points. The first is to analyze the current situation of smart home appliance control system and to conclude that the former home appliance control system adopts two schemes, power supply control scheme and infrared control scheme, on the basis of reading a large number of related papers. The advantage of the power supply control scheme is that the power supply of the household appliance is cut off directly, which can save electricity and avoid the external circuit failure, which causes burning out of the household appliance. The disadvantage is that it cannot be controlled for the household appliances, such as air conditioning, which need to be opened by remote control in order to run. The advantages and disadvantages of infrared control household appliances and power supply control is opposite; through the above analysis, we can see that the two schemes can complement each other, so this paper integrates the two schemes and adopts the mode of power supply and infrared dual control to control home appliances flexibly. Make up for the deficiency of individual control. The other is the design of the data monitoring system for human signs. All along, health problems have been paid attention to in production and life. With the development of Chinese society, people are paying more and more attention to their own health status and hidden dangers of disease and pulse. The heartbeat is an important feature of the human body, so monitoring these data is of practical significance; for people living at home, especially for the elderly and children, physical sign monitoring is very necessary; the bed is the household appliance closest to the human body. And the human body disease will lie on the bed rest, so the bed is the ideal monitoring platform; through the above analysis, this paper designed a physical sign monitoring system to obtain pulse, heartbeat and other physical signs data. Firstly, this paper puts forward the intelligent home system-home gateway and Zigbee networking scheme. The system design includes the hardware and software platform of home gateway and the hardware and software design of home appliance control. Physical sign data acquisition module hardware and software design Zigbee network and other parts. On the whole, the problems to be solved in this design are as follows: the home gateway platform includes the design of the S3C2440A peripheral interface of the home gateway processor; Finally, the boa server is ported and configured and the remote login management interface is designed. This paper focuses on the design and implementation of the home appliance control module and the physical sign data acquisition module, focusing on the design methods of software and hardware and the communication protocol of the system, the home appliance control module combines with the defects of the previous design scheme to improve the usability and expansibility. The module can be extended to the air conditioning control in the server room and other places, and the physical sign data acquisition module adopts piezoelectric thin film sensor and has an independent MCU, which can be independently used for data analysis, when the physical sign data is abnormal, Through the GSM communication module to the mobile phone to send reminders and signs data. Through the experiment test, the module can control the appliance, obtain the sign data and remind the short message, etc., the system realizes its expected function and achieves the expected design goal.
