【摘要】：随着社会的发展进步,提出智慧城市的设想也在逐步落实到国家城市规划中来,而智慧路灯管理控制系统作为市政建设的重要基础设施,是智慧城市建设的一个重要分支。本文针对于智慧城市路灯管理控制系统的需求,通过横向对比Zigbee等应用于工业自动化或者智能家居的物联网技术,选择了普及性广、适用性普遍、具备IP寻址、低功耗等优势的6LoWPAN技术。构建了基于6LoWPAN的智慧路灯管理控制平台,为此进行了如下一系列研究工作:改进了6LoWPAN分层路由协议HiLow。通过改进HiLow地址分配算法及路径恢复策略,使得分层路由协议能够较好地支持动态拓扑,增强了6LoWPAN网络的稳定性和路由协议的可靠性,仿真实验显示该算法能够很好地完成数据转发功能,通过维护节点在路由树中合理选择候选父节点确保路由树的负载均衡,网络性能提高的同时也使得节点生存时间有所延长。改进的Hi Low路由协议为6LoWPAN路由提供了一种比较好的可替代性解决方案。设计实现了由传感器节点、路灯控制器节点和6LoWPAN边缘路由器组成的智慧路灯控制平台的底层网络。通过安装在每盏路灯上的路灯控制器实现路灯的控制、监测、传感数据采集,组网通讯等功能,基于6LoWPAN无线自组网技术,在路灯与路灯之间实现数据通讯。通过路灯自组的网络,数据可以经由6LoWPAN边缘路由器,实现路灯与互联网之间信息互通。与此同时,智慧路灯控制器还可以通过RFID技术,采集来自有源电子标签、有源传感器的信号,实现传感网络的功能。
[Abstract]:With the development and progress of the society, the idea of putting forward the wisdom city is gradually implemented in the national urban planning. As an important infrastructure of the municipal construction, the intelligent street lamp management and control system is an important branch of the wisdom city construction. This paper aims at the demand of intelligent city street lamp management and control system, through the horizontal comparison of Zigbee and other application in industrial automation or smart home technology of Internet of things, choose a wide range of popularization, universal applicability, with IP addressing, Low power consumption and other advantages of 6LoWPAN technology. The intelligent street lamp management and control platform based on 6LoWPAN is constructed, and a series of research work is carried out as follows: improved 6LoWPAN hierarchical routing protocol HiLow. By improving the HiLow address allocation algorithm and path recovery strategy, the hierarchical routing protocol can support the dynamic topology well and enhance the stability of 6LoWPAN network and the reliability of routing protocol. Simulation results show that the proposed algorithm can complete the data forwarding function very well. By maintaining nodes reasonably selecting candidate parent nodes in the routing tree to ensure the load balance of the routing tree, the network performance is improved and the lifetime of the nodes is also extended. The improved Hi Low routing protocol provides a better alternative solution for 6LoWPAN routing. The intelligent street lamp control platform composed of sensor node, street lamp controller node and 6LoWPAN edge router is designed and implemented. The control, monitoring, sensing data acquisition and networking communication are realized by the street lamp controller installed on each street lamp. Based on the 6LoWPAN wireless ad hoc network technology, the data communication between the street lamp and the street lamp is realized. Through the street lamp self-organizing network, the data can be exchanged between the street lamp and the Internet via the 6LoWPAN edge router. At the same time, the intelligent street lamp controller can collect the signal from active electronic tag and active sensor through RFID technology, and realize the function of sensor network.
