为解决城市道路照明终端设备存在的耗电量巨大、管理困难、监控方式落后等问题,文中提出了基于地理信息系统(GIS)的路灯监测和控制方案,设计了基于ZigBee网络和GPRS网络的照明终端设备通信架构,以实现照明设备运行参数的自动、实时获取以及照明设备的节能策略运行、可视化管理与层次化控制等功能,解决因GPRS网络异常掉线和延时造成的数据丢失、地图界面加载海量标注缓慢等问题,提高数据传送效率和系统通信的可靠性.在合肥市某区的测试结果表明:文中提出的方案和架构能够在万盏路灯的实际应用中流畅运行,控制响应时间大约为1 s,与传统的自由控制运行相比节约了21.44%的电量.
In order to solve the problems such as huge power consumption, difficult management and backward monitoring methods of urban road lighting terminal equipment, a street lamp monitoring and control scheme based on geographic information system (GIS) is proposed in this paper, and the lighting based on ZigBee network and GPRS network is designed Terminal equipment communication architecture to achieve automatic, real-time access to lighting operating parameters and lighting equipment, energy-saving strategy operation, visualization management and hierarchical control and other functions to address the GPRS network due to abnormal dropped and delay caused by data loss, the map interface Load mass annotation slow and other issues to improve the efficiency of data transfer and system communication reliability.A test in a district in Hefei showed that: the proposed program and architecture can run smoothly in the practical application of 10000 lights, control the response time of about Is 1 s, saving 21.44% of electricity compared with the traditional free-control operation.
