搭建一个路灯电子镇流器组网的模拟实验系统,对集中控制终端和子终端进行通信流程设计,以实现上位机对集中控制终端、集中控制终端对子终端的命令传送,以及子终端对集中控制终端、集中控制终端对上位机的命令传回,特别对集中控制终端与子终端之间的电力线载波通信波形、数据,以及上位机接收到的数据进行实验研究,结果表明模拟组网系统成功实现了上位机、集中控制终端、子终端之间的通信.%A networking simulation experiment system for electronic ballast of street lamp is set up. The communication pro-cess is designed for the centralized control terminal and sub terminal to realize the command transmission from the upper computer to the centralized control terminal and the centralized control terminal to the sub terminal,and command return from the sub ter-minal to the centralized control terminal and the centralized control terminal to the upper computer. The experimental study was performed for the waveform and data of the power line carrier communication between the centralized control terminal and sub terminal,and data received by the upper computer. The experimental results show that the simulated networking system can realize the communication among upper computer,centralized control terminal and sub terminal successfully.
