| Abstract: | In this system several wireless communication units at the nodes of the water irrigationnet net can control the whole system remotely. The controlling devices are mainly composed of PLC, communication radio, communication modules, AC convertor and remote manometer. PLC controls communication radio and communication modules to realize communication between them, so that every communication unit works properly. |
