【摘要】：在科技、经济高速发展的今天,人们的生活水平也在不断的提高,追求的生活品质也相应的提高。因此,对于人们生活环境中不可或缺的家居环境,对它的安全、方便、舒适性的要求也越来越高。目前,应用得较为广泛的智能家居系统大多数是有线组网,但是它复杂的布线严重影响到了整个系统的美观、扩展能力,因此,智能家居系统现在向无线通信技术的趋势发展。具有近距离无线通信能力的ZigBee技术凭借着它的低功耗、低成本、组网灵活的优点,成为当今最适合于应用在无线组网的智能家居系统中的技术之一。在智能家居系统中,ZigBee无线网络承担着整个系统的数据发送、接收以及处理等任务。在文章中,首先对ZigBee技术的技术特点、网络结构以及相关的协议栈进行了研究。在设计智能家居系统终端节点的相关硬件结构进行设计时,选用TI公司的CC2430无线通信芯片,结合相关的外围电路完成了智能家居系统的无线网络硬件系统的搭建。在对整个智能家居系统的应用层进行设计时,首先根据实际需求提出了智能家居系统的功能需求以及整个智能家居系统的设计方案。然后在ZigBee协议栈的基础上,首先对ZigBee无线组网的程序部分进行了相应设计,接着根据总体的设计方案,对智能家居系统的各个功能模块的程序和硬件进行了详细的设计。在对功能模块进行设计时,根据模块完成的具体任务,对需要完成相关功能的传感器和控制器的型号做了选择和相关设计,并对整个系统中的信号采集和控制程序进行了详细的设计,实现了对室内外环境的温湿度、光照强度实时准确的采集,以及室内防盗、火灾、可燃气体的实时预警监控,以及室内的电子锁、窗帘的自动控制。最后对整个组建的智能家居系统的功能实现、功耗、性能进行了测试。将ZigBee无线网络技术应用在智能家居系统中,使得整个系统具有低功耗、非常高的灵活性、可扩展性等优点,具有非常高的应用推广价值。
[Abstract]:With the rapid development of science and technology and economy, people's living standard is improving and the quality of life is improving accordingly. Therefore, the requirement of safety, convenience and comfortableness is higher and higher for the home environment which is indispensable to people's living environment. At present, the most widely used smart home system is wired network, but its complex wiring seriously affects the beauty and expansion ability of the whole system. Therefore, the smart home system is developing to wireless communication technology. Because of its advantages of low power consumption, low cost and flexible networking, ZigBee technology with the ability of close wireless communication has become one of the most suitable technologies in wireless networking smart home system. In smart home system, ZigBee wireless network is responsible for sending, receiving and processing data in the whole system. In this paper, the technical characteristics, network structure and related protocol stack of ZigBee technology are studied. In the design of the related hardware structure of the terminal node of smart home system, the CC2430 wireless communication chip of TI company is selected, and the wireless network hardware system of the intelligent home system is built by combining the related peripheral circuits. In the design of the application layer of the whole smart home system, the function requirement of the intelligent home system and the design scheme of the whole intelligent home system are put forward according to the actual demand. Then on the basis of ZigBee protocol stack, the program of ZigBee wireless network is designed at first, and then the program and hardware of each function module of smart home system are designed in detail according to the overall design scheme. In the design of the function module, according to the specific tasks completed by the module, the model of the sensor and controller needed to complete the relevant functions is selected and related design. The signal acquisition and control program of the whole system is designed in detail. The real-time and accurate collection of indoor and outdoor environment temperature and humidity, the intensity of illumination, and the real-time warning and monitoring of indoor burglary, fire and combustible gas are realized. As well as indoor electronic locks, curtain automatic control. Finally, the function realization, power consumption and performance of the whole smart home system are tested. The application of ZigBee wireless network technology in smart home system makes the whole system have the advantages of low power consumption, high flexibility, scalability and so on.
