摘　　要：针对目前道路照明智能化过程中存在的路灯定位不准、通信质量不佳、智能化不足等问题,基于超宽带(UWB)技术设计了一种街巷智能路灯控制系统。该系统以UWB通信技术为基础,主要由路灯管理中心、智能配电柜、LED单灯控制器组成,使用循环迭代和卡尔曼滤波实现了使用有限数量的UWB基站实现了对全部路灯的精确定位,同时设计了基于结点状态的贪婪周边无状态路由协议(GPSR)自组网路由算法将路灯形成了数据通信网。测试表明该系统的响应迅速,平均单跳延时小于150 ms,分组投递率超过了90%,组网稳定可靠,通信实时性高,有效提高了道路照明系统的智能化,同时降低了建设、运营成本。Aiming at the problems of inaccurate positioning of street lamps, poor communication quality and insufficient intelligence in the process of intelligent road lighting, an intelligent street lamp control system based on Ultra Wide Band(UWB) technology is designed.Based on the UWB communication technology, the system is mainly composed of street lamp management center, intelligent power distribution cabinet,and LED single lamp controller. It used cycle iteration and Kalman filtering to achieve accurate positioning of all street lamps using a limited number of UWB base stations. At the same time, a node state based Greedy Peripheral Stateless Routing(GPSR) Ad hoc network routing algorithm was designed to form a data communication network for street lamps. The test shows that the system responds quickly, the average single hop delay is less than 150 ms, the packet delivery rate is more than 90%, the networking is stable and reliable, and the communication real-time is high, which effectively improves the intelligence of the road lighting system, and reduces the construction and operation costs.
