【摘要】：物联网被称为继PC机、互联网之后信息产业发展历程中的又一次技术革命。智能家居是物联网的主要应用领域之一，智能家居是在居民住宅或办公场所中安装多种设备，为用户提供快捷、舒适、安全的生活或工作环境的测控系统。环境数据采集系统是智能家居的重要组成部分，为了实时采集室内环境数据和无线传输数据以达到智能控制的目的，，本文基于ZigBee技术设计并实现了智能家居环境数据采集系统。首先，通过对比分析几种常见的短距离无线通信技术，选择将ZigBee无线通信技术应用到智能家居中。在分析市场上几种智能家居总体解决方案优缺点的基础上，基于项目的实际需求，制定了一套智能家居总体解决方案，并分析了环境数据采集系统在智能家居中的作用。其次，选取CC2530片上系统作为主芯片，选取DS18B20作为温度传感器，选取On9658作为光照强度传感器。确定了器件选型后，按照功能模块化的设计思想，使用Altium Designer6.9完成了系统的硬件设计，系统硬件主要由ZigBee无线通信模块、传感器模块、串口通信模块以及其他辅助模块构成。采用结构化程序设计思想，基于Z-Stack协议栈，在IAR集成开发环境下配合SZ_EMU仿真器完成了系统软件设计，程序主要功能是通过协议解析，完成设备入网、复位、退网以及采集室内环境数据和无线传输数据的工作。最后，搭建试验平台，对环境数据采集系统进行了测试。先对系统的各个功能模块进行了测试，包括ZigBee通信测试，设备入网、复位及退网测试，传感器采集数据和无线传输数据测试。再对系统的整体性能进行了测试，环境数据采集系统将采集的超过设定阈值的室内环境数据发送给网关，网关通过判断接收到的环境数据后给前端控制器发命令实现对空调以及灯的智能控制。测试结果表明环境数据采集系统能够完成预定的功能，具有较高的实用价值。
[Abstract]:The Internet of things is called the PC, the Internet after a revolution of technology development in the information industry. Home Furnishing intelligence is one of the main applications of the Internet of things, intelligent Home Furnishing is installed on a variety of equipment in residential or office space, to provide users with fast, comfortable, safe control system of living or working environment the environmental data acquisition system is an important part of the intelligent Home Furnishing, in order to collect the indoor environment data and wireless data transmission in order to achieve the purpose of intelligent control, this paper ZigBee technology to design and realize the intelligent data acquisition system based on Home Furnishing environment.
First of all, through the comparative analysis of several common short-range wireless communication technology, select the ZigBee wireless communication technology is applied to intelligent Home Furnishing. In the analysis of the market on the basis of several intelligent Home Furnishing solves all the advantages and disadvantages of the scheme, based on the actual requirements of the project, developed a set of intelligent Home Furnishing overall solution, and analyze the effect of environmental data in the intelligent acquisition system in Home Furnishing.
Secondly, select CC2530 system on chip as the main chip, the DS18B20 is chosen as the temperature sensor, the On9658 is chosen as the light intensity sensor. The selection of devices, according to the design idea of modularization, the use of Altium Designer6.9 to complete the hardware design of the system, the system hardware is mainly composed of ZigBee wireless communication module, sensor module, a serial port the communication module and other auxiliary modules. Using a structured program design method based on Z-Stack protocol stack, the IAR integrated development environment with the SZ_EMU simulator software system design is completed, the main function of program is completed through protocol analysis, network equipment, network back reset, and collecting the indoor environment data and wireless data transmission.
Finally, the experiment platform of environmental data acquisition system was tested. The various functional modules of the system were tested, including ZigBee communication test, network equipment, reset and back network test, sensor data acquisition and wireless data transmission test. Then the overall performance of the system was tested, the indoor environment data transmission environment the data acquisition system to collect more than a set threshold to the gateway, gateway environment data by judging the received command to the front controller to realize intelligent air conditioning and lamp control. The test results show that the environmental data acquisition system can accomplish the intended functions. It has a high practical value.
