【摘要】：随着城镇化的推进,路灯在人们生活中的作用越来越突出,也体现了一个城市的发展水平。一个城市的路灯系统耗电量是相当巨大的,在节能环保成为时代主题的今天,提高路灯系统的能量利用率是迫切需要的。当前我国大部分的路灯控制系统还是采用人工手动的方式,都存在管理困难、维护工作量大和运行可靠性差等缺点。基于此,本文设计了一种基于电力载波通信的路灯监控系统,该系统实现了对路灯的远程智能监控,具有成本低、节约能量、易于管理和维护等特点。本文通过对系统功能需求的分析和现有通信技术的比较,提出了路灯监控系统的整体架构方案,该系统采用三层结构,包括市政路灯监控中心、路灯集中器和路灯控制终端。市政路灯监控中心与路灯集中器通过以太网进行数据的远程传输,路灯集中器通过电力载波通信技术实现对区域中路灯控制终端的管理。路灯集中器的硬件设计主要包括载波通信单元、以太网接口单元和调制解调控制单元的设计。路灯控制终端的硬件设计主要包括载波通信单元、多种传感器单元、驱动单元和故障检测单元的设计。系统软件采用模块化程序设计的思想,设计了载波通信模块、Modbus协议模块、串口数据处理模块、ADC采样模块和中断处理模块等。本系统实现了路灯集中器对路灯控制终端的主从式监控。为了适用于大规模节点的应用场景,本文对电力载波通信路由算法进行了研究。最后本文对电力载波通信的可靠性进行了测试,并且分别在手动和自动工作模式下,对路灯监控系统进行了实验。实验结果表明,在自动模式下,该系统能够根据传感器采集的数据结合时钟芯片准确的控制路灯的开启和关闭;在手动模式下,路灯控制终端能够根据上位机发来的命令执行对应的操作,进而控制路灯的状态。本文还进行了蚁群算法的动态路由仿真实验,仿真结果表明:该算法能够找到从源节点到目的节点的最优路径,可以应用于电力载波路由组网。综上所述,本文设计的基于电力载波通信的路灯监控系统能够很好地实现路灯的管控,达到了设计的目标。
[Abstract]:With the development of urbanization, street lamp plays a more and more important role in people's life and reflects the development level of a city. The power consumption of a city's street lamp system is quite huge. In the era of energy saving and environmental protection, it is urgent to improve the energy utilization ratio of the street lamp system. At present, most of the streetlight control systems in our country still use manual method, which has the disadvantages of difficult management, heavy maintenance workload and poor reliability. Based on this, a street lamp monitoring system based on power carrier communication is designed in this paper. The system realizes the remote intelligent monitoring of street lamp, which has the characteristics of low cost, energy saving, easy management and maintenance. Based on the analysis of the functional requirements of the system and the comparison of the existing communication technologies, this paper puts forward the overall architecture of the street lamp monitoring system. The system adopts a three-layer structure, including the municipal street lamp monitoring center, the street lamp concentrator and the street lamp control terminal. The municipal street lamp monitoring center and the street lamp concentrator transmit the data remotely through Ethernet. The street lamp concentrator manages the control terminal of the street lamp in the area through the electric power carrier communication technology. The hardware design of street lamp concentrator mainly includes carrier communication unit, Ethernet interface unit and modulation and demodulation control unit. The hardware design of street lamp control terminal includes carrier communication unit, multi-sensor unit, drive unit and fault detection unit. The system software adopts the idea of modularization program design. The carrier communication module, Modbus protocol module, serial port data processing module, ADC sampling module and interrupt processing module are designed. This system realizes the master-slave monitoring of the street lamp control terminal by the street lamp concentrator. In order to be applicable to the application of large scale nodes, this paper studies the power carrier communication routing algorithm. Finally, the reliability of power carrier communication is tested, and the street lamp monitoring system is tested in manual and automatic mode. The experimental results show that the system can accurately control the turn on and off of the street lamp according to the data collected by the sensor and the clock chip in the automatic mode. In manual mode, the street lamp control terminal can perform the corresponding operation according to the command from the upper computer, and then control the state of the street lamp. The simulation results show that the algorithm can find the optimal path from the source node to the destination node and can be applied to the power carrier routing network. To sum up, the street lamp monitoring system based on power carrier communication can achieve the control of street lamp and achieve the goal of the design.
