Abstract：For the purpose of orchard water saving irrigation，we designed a set of sprinkler irrigation control system based on power line carrier communication. The system can get the field signal and control the actuator with master?鄄slave multicomputer communication mode based on power line carrier communication，and the host in the main control room as the core. Finally，the system test was carried out. Results show that the error rate is low，data transmission equipment operation is reliable，stable. The system not only achieve the control purpose，saves the water resources，at the same time to save a large amount of communication cable，and has the very good application value.
