Abstract For the purpose of water-saving irrigation, a set of the sprinkler irrigation control system was designed based on power line carrier communication. The system could get the field signal and control the actuator with master-slave multicomputer communication mode based on power line carrier communication means, and the host on the control centre room was as the core. Finally, the system test had been carried out. Results showed that the error rate was low, and the data transmission equipment operation was reliable and stable. The control distance reached about 300 m long. The system not only achieves the control purpose, saves the water resources, but also saves a large amount of communication cable, and has very good application value.

基于电力线载波通信的节水灌溉控制系统设计
为达到节水灌溉目的,设计了一套基于电力线载波通信的喷灌控制系统.系统以电力线载波为通信手段,以主控室的主机为核心,以主从多机通信模式对现场信号进行远程采集及控制,最后对系统进行了现场测试.结果表明,数据传输误差率低,设备运行可靠、稳定,控制距离达到了约300 m.系统不仅达到了控制目的,节约了水资源,同时节约了大量通信电缆,具有很好的应用价值.
