Real-time SCADA monitoring system

I. Product Introduction

Real-timeSCADAThe monitoring system is the core functional module of the wastewater plant's visual intelligent platform, used for centralized monitoring and management of the wastewater treatment process, on-site equipment, and key process parameters.

The system, through integration withPLCcontrol systems, on-site instruments, online water quality monitoring equipment, and other automation devices, collects and displays in real time the operating status of equipment such as water pumps, blowers, mixers, dosing equipment, and electric valves, as well as process parameters such as liquid level, flow rate, pressure, dissolved oxygen,pH, etc.

Through process flow diagrams, equipment status screens, real-time data, alarm lists, and historical trend curves, management personnel can centrally grasp the operating conditions of the wastewater plant at the monitoring center, promptly identify equipment faults and process parameter anomalies, and query relevant historical records.

The system can be integrated with the wastewater plant's 3D digital twin platform, equipment operation and maintenance system, energy consumption management module, and upper-level smart water platform according to project requirements, achieving data collaboration from on-site data collection and real-time monitoring to comprehensive operation management.

We can provide customizedSCADAmonitoring screen design, data interface development, alarm rule configuration, and system integration services based on the wastewater treatment process, equipment configuration, existing automation systems, and management requirements.

II. Main Functions

1. Real-time monitoring of wastewater treatment process flow

Display the operating conditions of each treatment unit in the wastewater plant through visual process flow diagrams, including inlet lifting, pretreatment, biological treatment, sedimentation, advanced treatment, disinfection, effluent, and sludge treatment, etc.

Management personnel can view the process flow, equipment status, and key operating parameters on a unified interface to understand the operational relationships between treatment units.

Main functions include:

l Process flow diagram display and zone switching

l Monitoring of operating status of main treatment units

l Real-time display of process parameters

l Association of equipment operating status with process screens

l Quick query of key process areas

Specific process screens are customized according to the wastewater treatment process and project design.

2. Monitoring of on-site equipment operation

Centrally monitor the operating status of main electromechanical equipment on site to help management personnel understand whether the equipment is operating normally and whether there are abnormalities.

Monitoring objects may include:

l Inlet pumps, lifting pumps, and return pumps

l Aeration blowers and related auxiliary equipment

l Mixers, sludge scrapers, and sludge treatment equipment

l Dosing pumps and dosing systems

l Electric valves, gate valves, and other actuators

l Frequency converters, soft starters, and related electrical equipment

The system can display information such as equipment running, stopped, fault, manual or automatic mode based on status signals provided by the on-site control system. The specific status types depend on the on-site signal configuration.

3. Real-time collection and display of process parameters

Connect to on-site instruments and monitoring equipment to centrally display key operating data during the wastewater treatment process.

Parameters that can be monitored include:

l Hydraulic parameters: liquid level, flow rate, pressure, etc.

l Water quality parameters: pH, dissolved oxygen, turbidity, and other configured online monitoring indicators.

l Equipment parameters: motor operating status, current, frequency, and other collectable data.

l Operation statistics data: inlet and outlet flow, equipment running time, and related cumulative values.

The system can set parameter units, display precision, data refresh methods, and over-limit judgment rules according to project requirements.

4. Real-time alarms and anomaly management

Connect to alarm signals from on-sitePLC, instruments, and other monitoring equipment, and centrally display equipment faults, parameter over-limits, communication anomalies, and other configured abnormal events.

Main functions include:

l Real-time alarm list and alarm status display

l Alarm level classification

l Recording of alarm occurrence time and related equipment information

l Alarm acknowledgment and historical query

l Alarm statistics and handling records

l Optional SMS, email, or mobile alarm notifications

Alarm thresholds, alarm levels, and notification methods are configured according to project requirements. Functions involving equipment protection and emergency shutdown should be executed by the on-site control system and corresponding protection circuits as designed, and must not rely solely on monitoring software.

5. Historical data and trend curves

The system can save on-site operating data and alarm records as configured, providing a basis for operation analysis, troubleshooting, and management traceability.

Main functions include:

l Real-time data and historical trend curves

l Data query for specified time periods

l Multi-parameter trend comparison

l Historical alarm query

l Equipment operation record query

l Data export and report generation

The sampling cycle, storage cycle, retention period, and export format of historical data are determined according to project scale, database configuration, and storage resources.

6. Equipment remote operation and control interface

When supported by the on-site control system, permitted by user permissions, and meeting safety conditions, authorized remote operations can be executed through the monitoring interface, such as equipment start/stop, operation mode switching, or setpoint adjustment.

Main functions may include:

l Display of manual and automatic operation mode status

l Input of remote operation commands

l Operation permission verification

l Display of operation results and equipment feedback status

l Saving of operation records and audit information

Remote control functions must be designed in combination with on-sitePLCcontrol logic, equipment interlocking, operation permits, and safety strategies. When communication is interrupted or the monitoring platform fails, on-site basic control and necessary protection should maintain corresponding operating capability according to project design.

7. Linkage with 3D digital twin platform

Real-timeSCADAdata can be associated with the wastewater plant's 3D digital twin model, enabling equipment operating status and process parameters to be displayed intuitively in the 3D scene.

For example, when management personnel select a water pump in the 3D scene, they can view its operating status, related parameters, and alarm information; when a device is abnormal, the corresponding equipment or process area can be located in the 3D scene according to configuration.

This function requires completing the data association between equipment codes, monitoring points, and the 3D model, and configuring corresponding interfaces according to project requirements.
