The intelligent monitoring system for joint operation of surface water and groundwater,which purpose is to control the groundwater level,consists of two relatively independence parts:the numerical simulation system of both surface water and groundwater and the computer monitoring system.The two parts could exchange data by Access.The internal system and the operational flow were information collecting layer, scheduling decision layer and decision execution layer.The external structure was composed of one data analysis and treatment center station and some control slave stations which set from monitoring spots.The wireless data transmission was used for the connection from the center station to the slave stations.Data were acquired by a computer monitor part, and divided into different water distribution ratios,then sent to the numerical simulation system for simlation and prediction.The optimal water distribution plan would be chosen in human computer mode.Then the control instructions would be sent from the computer screen virtual operating panel.The concrete irrigation would be actualized by computer monitoring system.The intelligent monitoring system was modular design, distributing, human computer interaction, information collection, scheduling decision and decision execution.The sub monitoring system station CPU with the sleep and wake up working mode could reduce the interfered probability.The AC 100 V，25 mA was applied to the contact and to improve reliability in long term operation in moist environment.The system design concept was advanced and the structure was rational.Field test proved that this system works reliably.This system could provide reference for the further study of same system.
