【摘要】：目前办公室智能照明系统大多采用有线方式将灯与控制器相连以实现控制,并且组网设备中的开关和传感器通常需要电池或电源供电,系统安装需要开槽布线,维护需要频繁更换电池。本文采用无线组网技术和室内光能量采集技术实现的无源无线办公室智能照明系统,安装无需开槽布线,开关和传感器等设备实现了能量自给,无需维护。本文主要针对办公室智能照明系统中的无线组网技术和光能量采集技术进行了深入研究,实现了无电源线、无数据线的组网设备。本文总体介绍了无线办公室智能照明系统的总体方案,设计了系统中的无线网关和节点模块。设计了一种采集室内微小光能的自供电无线信号发射器,实现了无源无线的开关与传感器。给出了无线网络的拓扑结构设计,提出了网络的建立、节点的入网流程设计方案。同时设计了网络数据传输机制与设备自恢复机制,该机制保证了网络数据的稳定传输。在无线组网技术的快速自组网过程中,往往会由于多种原因产生信息孤岛,从而导致网络资源利用不充分。本文提出了一种基于虚连接技术配合手持检测设备的快速搜索机制,并且对该机制进行了理论分析和仿真分析。分析表明,该机制不仅能有效搜索到信息孤岛,且处理效率较传统搜索方法高。本文开发了无线网络的测试软件与空中无线数据包的截取分析工具,用于无线网络的监测分析。最后本文对系统中的无线网络进行了丢包率与功耗测试。测试数据表明本文设计的无线网络可以达到办公室智能照明系统的预期需求。
[Abstract]:At present, most office intelligent lighting systems use wired way to connect the lamp to the controller to realize the control, and the switch and sensor in the networking equipment usually need battery or power supply, and the installation of the system needs slot wiring. Maintenance requires frequent battery replacement. In this paper, the passive wireless office intelligent lighting system is realized by wireless networking technology and indoor light energy acquisition technology. The intelligent lighting system of wireless office is installed without slot wiring, and the devices such as switches and sensors are self-sufficient in energy and do not need maintenance. In this paper, the wireless networking technology and the optical energy acquisition technology in the office intelligent lighting system are studied deeply, and the network equipment without power line and data line is realized. In this paper, the overall scheme of wireless office intelligent lighting system is introduced, and the wireless gateway and node module are designed. A self-powered wireless signal transmitter for collecting indoor micro light energy is designed to realize passive wireless switch and sensor. The topology design of wireless network is given, and the establishment of network and the design scheme of node access flow are put forward. At the same time, the network data transmission mechanism and the device self-recovery mechanism are designed, which ensures the stable transmission of network data. In the process of fast ad hoc wireless network technology, information island is often produced for many reasons, which leads to insufficient utilization of network resources. In this paper, a fast searching mechanism based on virtual connection technology and handheld detection device is proposed, and the theoretical analysis and simulation analysis of this mechanism are carried out. The analysis shows that the mechanism not only can effectively search the isolated information islands, but also has higher processing efficiency than the traditional search method. In this paper, the test software of wireless network and the interception and analysis tool of wireless data packet in the air are developed, which can be used for monitoring and analysis of wireless network. Finally, the packet loss rate and power consumption of wireless network in the system are tested. Test data show that the wireless network designed in this paper can meet the expected demand of office intelligent lighting system.
