中文摘要:
      为了克服现有城市道路照明路灯控制系统难以兼顾节能与保障行车安全的问题,提出一种城市道路照明自适应节能控制算法,该算法采用路面实时平均亮度反馈,在日出日落时段与基于标准设计的路面需求亮度比较,自适应地调整实际开关灯时间,并依据道路小时统计平均车流量,在夜间照明时段按小时计算对应的道路照明亮度,实现与车流量统计结果相匹配的分时段调光控制策略,既能保障行车安全,又能实现明显的节能. 详细描述了算法的工作原理与程序实现流程图,介绍了基于LoRa无线物联网城市道路照明监控系统的结构与功能. 该系统在湖南省某条干道夏季相同天气条件和时间内的实际运行效果表明:系统能可靠实现区域道路路灯的远程无线开关灯与调光控制等监控功能,验证了节能型自适应控制算法的有效性,相比于传统控制方式的节能率高达39.3%.
英文摘要:
      In order to overcome the problem that the existing urban road lighting street lamp control systems are not able to balance energy saving and driving safety,an adaptive energy saving control algorithm for urban road lighting is proposed and studied. The algorithm uses real-time average brightness feedback on the road surface,compares the brightness of the road surface based on the standard design during sunrise and sunset hours,adaptively adjusts the actual switch light time. According to the average traffic flow of the road hours,the corresponding road lighting brightness is calculated by the hour during the night lighting period,realizing the time-division dimming control strategy that matches the statistical results of the traffic flow,which can guarantee driving safety and realize obvious energy saving. It describes the working principle of the algorithm and the flow chart of the program in detail,and introduces the structure and function of the urban road lighting monitoring system based on the LoRa wireless internet of things. The actual operation effect of the system in the same weather conditions and time on a main road in Hunan Province in summer shows that the system can reliably realize the monitoring functions of the remote wireless switch and dimming control of the regional road street lights,verifying the effectiveness of the energy-saving adaptive control algorithm,with an energy saving rate of 39.3% compared with the traditional control methods.
