为了解决日常生活中路灯能量利用率低、难以智能控制等问题,本文设计一种基于GSM和电力载波通信技术的路灯监控系统,通过引入蚁群算法寻找集中控制器到目的终端之间的一条最优传输路径,实现了对路灯的实时和智能监控。文中介绍了该监控系统的总体结构和软硬件设计,重点是路灯控制终端的设计和蚁群算法寻优的实现,最后分析了系统的应用情况。该系统由路灯控制终端、路灯集中控制器和监控中心组成,其中路灯控制终端采用STC12C2052AD作为微处理器,控制载波通信模块KQ130F+实现路灯节点之间的通信,并根据各传感器检测的环境参数智能控制路灯。路灯控制终端通过电力线将数据发送给路灯集中控制器,接着数据通过GSM网络传输到控制中心。仿真测试表明,蚁群算法能根据通信链路的连接情况和不同服务的要求找到电力载波通信网络的最优路径,具有成本低、易操作和节能的特点,满足了路灯控制的需求。

In order to solve the low-vsage problem of streetlights in daily life, such as low utilization of energy and difficult to control intelligently, this paper puts forward a streetlights monitoring system based on GSM and PLC technology by introducing ant colony algorithm to find an optimal path from the centralized controller to the destination terminal to achieve real-time and intelligent monitoring of streetlights. It describes the overall structure of the monitoring system,hardware and software design, focuses on the street light control terminal design and the realization of ant colony algorithm optimization and analyzes the application of the system. The system is composed of streetlights control terminal, streetlights centralized controller and monitoring center. STC12C2052AD single-chip microcomputer is used as a microprocessor for the streetlights control terminal. It controls the PLC modules KQ130F＋to realize communication between streetlight nodes and intelligently controls streetlights based on environment parameters detected by sensors. The control terminal transfers data to the centralized controller though the power line, then, the data is sent to the monitoring center by GSM net. The simulation tests show that ant colony algorithm,based on the connection of the communication link and the different service requirements, can find the optimal power line carrier communication network paths. The system has low-cost, easy operation and energy saving features and meets the needs of street light control.
