Advantech provided a remote and centralized monitoring system for this case. The system can be divided into two major parts: on-site data processing and collection, and SCADA/HMI control operation. For on-site data processing and collection, Advantech APAX-5017, APAX-5040, and APAX-5046, I/O modules, are implemented to collect data, and then the EKI-2526S industrial-grade Ethernet switch, is used for data transmission. The APAX-5017, Analog Input Module, is used to collect pH meter and water level data while the APAX-5040, as a Digital Input Module, monitors the status of the water level and pump, and sends the alarm to control center when there’s a malfunction. The APAX-5046, Digital Output Module controls the on/off buttons of the pumps and field devices. All the data is then sent to the compact and robust APAX-5520KW controller, which supports customized waste water treatment functions to develop an entire waste water treatment process, such as: metal, aerating, sludge and scum removal, the killing of bacteria and the removal of waste water residuals.
The other support logic control functions are for the pump, motor, valve control and the transferring of the parameters to the control room via an EKI-2525 unmanaged industrial Ethernet switch.At this data collection stage, fiber-optic communication plays a critical role in enabling the plant to expand its industrial network quickly and cost-effectively because EKI products support high-speed and long-distance transmissions. Meanwhile, with a high performance processor and large storage capability, the APAX-5520KW can act as a standalone controller for controlling I/O modules so as to provide local control features.
For remote management, Advantech provided a TPC-1270 12.1" SVGA LED LCD Celeron M/ Touch Panel Computer, with HMI/SCADA Software and Advantech WebAccess, to display all kinds of data immediately, therefore allowing engineers to remotely tune or manipulate the on-site equipment operations in the control center. The system also provides real-time alarms, historical data analysis, data sharing, automatic report generation, and many other management functions to meet the plant’s monitoring requirements as well as reaching the goal of centralized management and distributed control.
