研華解決方案的關鍵是無線通信。使用 ADAM-4550 無線調製解調器模塊，研華可以在每個泵站與中央控製室之間提供 2.4 GHz 的de無wu線xian通tong信xin連lian接jie。由you於yu廣guang泛fan分fen布bu的de泵beng站zhan覆fu蓋gai了le廣guang大da區qu域yu，因yin此ci無wu線xian連lian接jie大da大da減jian少shao了le電dian纜lan成cheng本ben以yi及ji由you此ci而er來lai的de有you關guan問wen題ti，同tong時shi增zeng加jia了le通tong信xin連lian接jie的de可ke靠kao性xing。如ru果guo選xuan擇ze更geng長chang距ju離li的de天tian線xian，可ke以yi增zeng加jia ADAM-4550 的通信範圍。 研華的解決方案也將 ADAM-4012 模擬量輸入模塊用於監測水位的傳感器和泵站電腦之間的數據連接。水泵的控製使用 ADAM-4060 繼電器輸出模塊。閘門的開放與關閉由 ADAM-4050 數字量輸入輸出模塊來控製。所有這些信號通過 RS-485 網絡傳送，在經過 ADAM-4520 RS232/422/485 轉換器將其轉換成 RS-232 信號之後送入到本地電腦。
