A wastewater treatment plant operates multiple PLC master stations across various process areas, including distribution wells, blower rooms, biological tanks, highefficiency sedimentation and filtration units, reclaimed water pump rooms, heat pump rooms, and sludge dewatering facilities. These stations enable automated control and monitoring of equipment throughout the entire treatment process. The plant now requires that all operational data be uploaded to a cloudbased SCADA platform to support remote monitoring, alerting, management, and control functions, thereby elevating its digital management capabilities. To meet this need, WideIOT provides a robust and reliable solution.

System Architecture

Field Perception Layer – Comprises PLC master stations and field instrumentation across all process stages, including distribution wells, biological tanks, blower rooms, filtration units, heat pump rooms, and sludge dewatering facilities.
Data Acquisition Layer – WideIOT industrial intelligent gateways connect to all PLC master stations, as well as field instruments, variable frequency drives, cameras, and other onsite devices. The gateways collect real‑time data and transmit it via 5G/4G to the cloud SCADA platform.
Cloud SCADA Platform Layer – The WideIOT cloud SCADA platform integrates multiple functional modules, including graphic configuration editing, visual monitoring, alarm management, data analytics, and maintenance workflow management. Plant managers and operators can gain full visibility into plant operations anytime, from anywhere.

Key Features

1. Precise Data Acquisition Across the Entire Process – Compatible with a wide range of multi‑site, multi‑protocol devices, the system captures real‑time process parameters and equipment status, standardizes data formats, and ensures high accuracy and reliability.
2. CloudBased Visual SCADA Monitoring – Drag‑and‑drop configuration allows users to build custom process monitoring screens. The system supports simultaneous access from multiple devices (PCs, tablets, smartphones) and can integrate live video streams, providing intuitive, real‑time visibility into plant‑wide operations.
3. Tiered Intelligent Alarm Notifications – Customizable threshold settings trigger alerts via WeChat, SMS, or email, with precise message routing. An automatic event log is maintained, enabling quick fault tracing and root cause analysis.
4. Closed‑Loop Digital Maintenance Management – Maintenance work orders can be generated online with full traceability. Remote PLC debugging and program upload/download capabilities significantly reduce on‑site service costs and troubleshooting time.
5. Data‑Driven Process Optimization – Automatically generated multi‑dimensional production reports help uncover patterns in operational data, supporting optimization of aeration, chemical dosing, and other key parameters to achieve energy savings and cost reduction.
6. Secure Data Interoperability and Access Control – Open API interfaces enable seamless integration with environmental regulatory platforms and existing enterprise systems. Role‑based permission controls ensure operational security while meeting compliance reporting and data sharing requirements.
