【摘要】：随着人们收入水平的提高，生活环境质量也逐渐被人们所重视。近几年，城市的高速发展带来了严重的环境污染问题。在国内将近1/3的大中型城市相继出现了严重的雾霾天气。而由雾霾天气导致的呼吸道疾病也在呈上身趋势。相对于室外环境，室内环境质量的高低直接影响着家人的健康。国外在很早就开始了对室内环境的质量的调查和研究，一些研究成果和国家支持带动了室内环境控制系统在西方国家的高速发展。随着相关生产商的一些推广，很多智能家居产品中已加入了室内环境控制子系统。智能家居的概念从提出到现在将近20年之久，发展到今天已经进入了一个空前的高速发展阶段。作为一种全新的综合技术，智能家居系统中主要涵盖有无线组网，协议转换，计算机网络等相关领域的知识。作为智能家居系统的一员，室内环境控制系统是基于ZigBee无线传感网络建立的采样数据上传和控制命令下发的无线自组网络。与传统实现方式相比，降低了成本，节约了开发周期。 ZigBee作为一种全新的无线局域网技术，继承了许多无线技术的优点，并在此基础上增加低功耗和自组网的创新。与此同时，一些低成本的射频芯片解决方案也相继出现，迎合了市场需求。这其中就包括著名的IC生产厂商Texas Insrument。其生产的CC2530芯片虽然成本低廉，但功能齐全，配合着其发布的ZigBee协议栈代码Z-stack,两者完美的实现了ZigBee无线传感控制网络的建立和运行。在用户层面，由于网关设备的加入，使得整个系统连接到以太网络，ZigBee网络内的采样数据可以及时的更新到而用户也可以使用个人终端，通过远程互联网访问来下发控制命令。基于ZigBee无线组网技术的室内环境控制系统，建立在Texas Instrument的ZigBee解决方案之上，适用于网络规模较小的家居环境。传感节点和控制节点都被烧录相应代码。当所有节点上电后，依次自动加入到整个ZigBee网络。中心网关的功能创新以及硬件的高度集成不但使得整套系统更加简便，而且大大节约了开发成本。如此一来，，本方案在低成本智能家居产品的普及上可作为参考。而对室内环境控制系统的发展也具有一定的借鉴意义。
[Abstract]:With the improvement of people's income level, the quality of living environment has been paid more and more attention. The rapid development of cities has brought serious environmental pollution problems. In nearly 1/3 large and medium-sized cities in China, severe haze weather has occurred one after another. Respiratory diseases caused by haze weather are also showing a trend of upper body. Compared with outdoor environment, The quality of indoor environment has a direct impact on the health of the family. The investigation and research on the quality of indoor environment began early in foreign countries. Some research results and state support have driven the rapid development of indoor environmental control system in western countries. With the promotion of some related manufacturers, many smart home products have added indoor environment control subsystem. The concept of smart home has entered an unprecedented rapid development stage since it was proposed for nearly 20 years. As a new comprehensive technology, smart home system mainly covers wireless networking and protocol conversion. Knowledge of computer network and other related fields. As a member of smart home system, Indoor environment control system is a wireless ad hoc network based on ZigBee wireless sensor network, which can upload sampling data and send control commands. Compared with the traditional implementation, it reduces the cost and saves the development cycle. As a new wireless LAN technology, ZigBee inherits the advantages of many wireless technologies, and on this basis increases the innovation of low power consumption and ad hoc network. At the same time, some low-cost RF chip solutions have emerged. It caters to market demand. This includes the well-known IC manufacturer Texas Insrument.Its CC2530 chips are inexpensive but fully functional. With the ZigBee protocol stack code Z-stack, both of them perfectly realize the establishment and operation of ZigBee wireless sensor control network. At the user level, because of the addition of gateway equipment, the whole system can be connected to the Ethernet network ZigBee network sampling data can be updated in time, and the user can also use personal terminals to send control commands through remote Internet access. The indoor environment control system based on ZigBee wireless networking technology is based on the ZigBee solution of Texas Instrument, which is suitable for the home environment with small network scale. The sensor node and the control node are burned and the corresponding codes are recorded. The function innovation of the central gateway and the high integration of hardware not only make the whole system easier, but also save the development cost. This scheme can be used as a reference for the popularization of low-cost smart home products, and also has certain reference significance for the development of indoor environment control system.
