【摘要】：本文根据国内外路灯的研究现状、发展趋势及国家“十城万盏”发展计划,针对传统路灯系统中存在的调节操控能力不足、开关灯方式落后、不具备灯具实时状态监测、节能方案不足等问题,提出了一种基于电力载波的智能路灯控制系统的解决方案。为了达到路灯节能和便捷管理的目的,系统设计采用以下方法:(1)采用GPRS无线通信技术将路灯数据实时传送至云服务器,用户可以及时查看路灯状态,网络通信中使用心跳间隔自适应算法保证客户端和云服务器TCP长连接;(2)通过电力载波通信技术可以对单/双灯控制器进行控制和数据采集;(3)使用PWM技术实现了对LED灯具亮度的调节,根据策略或用户命令调节路灯的亮度,从而达到“二次节能”效果。系统由云服务器、集中器、单/双灯控制器、客户端四部分组成。通过本系统用户可以方便的对路灯进行远程控制、状态监控、亮度调节及数据采集,改进了路灯的控制方式,并且提高了路灯的节能效率。本文首先从课题研究意义、国内外研究现状等方面介绍路灯控制系统,分析归纳了系统的需求。然后给出了系统的设计方案,论述系统涉及的GPRS、电力载波、PWM调光等关键技术,并对方案的可行性进行了分析。对系统各部分软件进行了设计,介绍了部分硬件的原理框架,并对系统中使用的GDW1376.2协议、DL/T645协议进行分析。最后,对系统的策略、远程控制、数据采集等功能进行测试。该系统功能稳定、体验良好,达到了设计要求。
[Abstract]:According to the current research situation of street lamp at home and abroad, the development trend and the national development plan of "ten thousand cities", aiming at the deficiency of regulating and controlling ability in the traditional street lamp system, the mode of switch lamp is backward, and the real-time state monitoring of lamps is not available. An intelligent streetlight control system based on power carrier is proposed. In order to achieve the purpose of energy saving and convenient management of street lamp, the following methods are adopted in the system design: (1) the data of street lamp is transmitted to cloud server in real time by using GPRS wireless communication technology, and the user can view the status of street lamp in time. In network communication, the adaptive algorithm of heartbeat interval is used to ensure the long TCP connection between client and cloud server; (2) single / double lamp controller can be controlled and data collected by power carrier communication technology; (3) PWM technology is used to realize the control and data acquisition of single / double lamp controller. LED luminance adjustment, Adjust the luminance of the street lamp according to the policy or user order, so as to achieve the "second energy saving" effect. The system consists of cloud server, concentrator, single / double lamp controller and client. Through the system users can conveniently remote control, state monitoring, brightness adjustment and data acquisition, improve the control mode of street lamps, and improve the energy-saving efficiency of street lamps. This paper first introduces the streetlight control system in terms of the significance of the research and the current research situation at home and abroad, and analyzes and sums up the requirements of the system. Then the design scheme of the system is given, and the key technologies such as GPRS, power carrier PWM dimming are discussed, and the feasibility of the scheme is analyzed. The software of each part of the system is designed, the principle frame of some hardware is introduced, and the GDW1376.2 protocol (DL- T645) used in the system is analyzed. Finally, the system strategy, remote control, data acquisition and other functions are tested. The system has stable function, good experience and meets the design requirements.
