【摘要】：随着现代生活质量的不断提高,人们对家庭环境的重视程度也在不断的提升,对家庭设备的智能化、节能化也提出了更高的要求。目前室内监控系统的设备组网研究多采用ZigBee+网关或者蓝牙+网关模式,连入的是IPv4的网络,但是随着移动设备不断的接入互联网,IPv4地址已经耗尽,IPv6势在必行。并且ZigBee+网关的连接方式由于底层设备不能直接接入互联网,因此不能实现点到点的通信。如果想要实现点到点的通信,需要底层设备也能实现IPv6协议,但是通常底层设备的硬件资源有限,无法提供运行IPv6所需的资源,为了解决这个问题,IETF提出了6LoWPAN协议。本文在研究了6LoWPAN技术的基础上,设计了一个基于6LoWPAN的室内环境监控系统。系统由信息采集模块、灯控终端和网络协调器等部分组成。信息采集模块采集室内环境参数,灯控终端根据照度及人员情况进行调光操作,网络协调器则是负责组建网络及进行信息的初步处理及传递。本文所做的主要工作如下:首先设计并实现了系统信息采集模块,系统信息采集模块包含有害气体、红外热释电人体、温湿度、光照度等信息采集模块。信息采集模块以JN5168模块为核心,加上传感器、UART串口、电源电路等组成。然后实现了一个6LoWPAN网状网络结构,在各个节点中采用JenNet-IP协议栈,实现数据在6LoWPAN中的传输。进而设计实现了网络协调器,解决了网络的组建及6LoWPAN网络与互联网之间由于网络结构不同所产生的数据报传输、处理等问题。最后搭建了整个室内环境监控系统,并进行了系统功能的测试,即灯控终端对智能灯具的调节测试,信息采集系统信息的采集及上传测试,网络协调器的数据传输测试等。测试结果表明,本方案能够较好的实现室内环境监控系统对智能调光及环境信息数据采集的要求。
[Abstract]:With the continuous improvement of the quality of modern life, people pay more attention to the family environment, and put forward higher requirements for the intellectualization and energy-saving of the family equipment. At present, ZigBee gateway or Bluetooth gateway mode is used in the research of equipment networking in indoor monitoring system, which is connected to the IPv4 network. However, with the continuous access of mobile devices to the Internet, IPv4 address has been exhausted. And the connection mode of ZigBee gateway can not realize point-to-point communication because the underlying device can not directly connect to the Internet. If you want to achieve point-to-point communication, you need the underlying device to implement the IPv6 protocol, but usually the underlying device has limited hardware resources and cannot provide the resources needed to run IPv6. In order to solve this problem, 6LoWPAN protocol is proposed. Based on the research of 6LoWPAN technology, an indoor environment monitoring system based on 6LoWPAN is designed in this paper. The system consists of information acquisition module, lamp control terminal and network coordinator. The information acquisition module collects indoor environmental parameters, and the lighting control terminal adjusts the light according to the illumination and personnel conditions. The network coordinator is responsible for setting up the network and carrying out the preliminary processing and transmission of information. The main work of this paper is as follows: firstly, the system information acquisition module is designed and implemented. The system information acquisition module includes harmful gas, infrared pyroelectric human body, temperature and humidity, illumination and other information acquisition module. The information acquisition module is composed of JN5168 module, sensor UART serial port, power circuit and so on. Then a 6LoWPAN network structure is implemented, and the JenNet-IP protocol stack is used in each node to realize the data transmission in 6LoWPAN. Then the network coordinator is designed and implemented, which solves the problems of network construction and Datagram transmission and processing between 6LoWPAN network and Internet due to the difference of network structure. Finally, the whole indoor environment monitoring system is built, and the function of the system is tested, that is, the adjustment test of the lamp control terminal to the intelligent lamp, the information collection and upload test of the information collection system, the data transmission test of the network coordinator and so on. The test results show that this scheme can meet the requirements of intelligent dimming and environmental information data collection in indoor environment monitoring system.
