Architecture design for water resources real-time monitoring and management system based on OPC

In consideration of the fact that the conventional software structure does not adapt to the complex real-time water resources monitoring and management system, an open software structure of three-tier was put forward based on the OPC and component techniques, and a detailed explanation of its tier structure was given. The software structure is of good openness and high flexibility, compatibility, reliability and maintainability and suitable for the water resources monitoring and management system for large areas and river basins.
