基于MSP430的智能家居系统设计摘要基于MSP430的智能家居系统设计

摘要

近年来，随着当代通信技术、计算机信息技术和各项传感网技术的大范围应用，作为物联网技术当中一个非常重要和典型的应用实例智能家居获得了迅速发展。相较于传统的家庭自动化，现代智能家居系统以无线组网技术、现代传感技术为基础，克服了传统家居环境中存在的布线复杂、可靠性性低、升级繁琐等诸多缺点，给人们带来了更加安全、健康、智能的生活环境。在未来的时间里智能家居系统必将会得到更加广泛的应用。

一个完整的智能家居系统主要由家居内部网络、家庭网关和家居外部网络三个部分构成。本文以美国德州仪器公司生产的超低功耗微控制器MSP430F6638为控制核心，在充分研究各种无线通信和组网技术的基础上，选择ZigBee无线通信方式组建家居内部网络，选择Wi-Fi无线通信方式组建家居外部网络，以此为基本框架构建了一套实用的智能家居系统。

本文设计的智能家居系统主要包括家庭网关控制中心子模块、ZigBee网络通信子模块、数据采集和设备控制子模块以及Wi-Fi网络通信子模块。文中给出了各个子模块具体的硬件设计过程、软件设计过程和实现过程。系统经过设计、制作、调试，最终实现了家居内部温度数据采集、光照强度数据采集、有害气体浓度检测与控制以及智能灯光控制等数项基本功能。同时为了提高系统的可拓展性，本文设计的智能家居系统一方面留有了丰富的接口资源用以扩展新设备，另一方面软件采取了模块化设计方案独立性较强，便于后期添加新功能。

本论文对所设计的智能家居系统的各项基本功进行了调试验证，测试结果表明设计达到了预期效果，具有较高的可靠性和实用价值，也为同类产品的设计和开发提供了一个参考。

DESIGN OF MSP430 BASED SMART

HOME SYSTEM

Abstract

In recent years, with the application of modern wireless communication technology, information technology and sensor technology, the Internet of Things (IOT) and its related industry has been developed rapidly. As one of the most important application of the IOT, smart home has attracted more and more people’s attention. Compared to the traditional wired home automation, modern smart home has overcome many shortcomings, such as cumbersome routes and low reliability. A more comfortable and intelligent home condition will be created by the modern smart home system in the future.

A complete smart home system mainly consists of three basic parts, the home network, home gateway and external network. In this thesis, the MSP430F6638 microcontroller produced by Texas Instruments was selected as the core processor of the home gateway. Various kinds of wireless communication technology were researched and finally ZigBee and Wi-Fi were adopted as the wireless technology to construct the home network and external network respectively.

The designed smart home system includes several modules: the ZigBee communication module, Wi-Fi communication module, gateway control module, sensors’data acquisition module and home condition control module. The hardware design and software design of each module is illustrated in detail. The designed hardware system was produced, assembled, and debugged. Combined with the designed software, temperature and humidity acquisition, illumination intensity acquisition , poisonous gas monitoring and intelligent lighting control were realized. Furthermore, in order to improve the expandability of the system, some expandable interfaces are reserved in the hardware system and modularization software design scheme is adopted by this thesis.

The functionalities of the designed smart home system were tested and adjusted. The
