Siemens SCADA Monitoring System Integration Case: Songjiang Tianma Phase II Leachate Treatment Project – Data Integration and Wireless Transmission for Leachate Treatment Phases I & II

The Songjiang Tianma Phase II Leachate Treatment Project requires expanding monitoring capabilities on top of the existing Phase I system. The site currently hosts Siemens SCADA systems, DCS systems, and controllers from multiple vendors, resulting in incompatible communication protocols. Data from Phase I and Phase II are isolated, making centralized operations and maintenance difficult. Project scope includes: - Integrating and designing the consolidation of the Siemens SCADA system. - Enabling OPC protocol data transmission for the DCS system. - Collecting terminal device data and transmitting it via RS485 communication. - Consolidating data from both Phase I and Phase II plants and enabling wireless transmission. - Acquiring, processing, and transmitting PLC data. - Standardizing communication protocols for various device controllers and performing data acquisition and processing. After modernization, data from both phases will be unified under a single monitoring framework. Operations staff can view the status of all device controllers from a central control hub, with anomalies immediately traceable to specific sites and equipment.
