IOT News

A certain power plant has implemented a Distributed Control System (DCS) and requires remote monitoring and control capabilities for its pump station.This includes collecting switch status signals such as the operation, fault, readiness, and valve positions of pump station equipment, as well as critical analog signals such as current, liquid level, pressure, and motor current. Additionally, it necessitates the ability to remotely control valve start-stop operations. In response, WideIOT offers an efficient and reliable IoT solution.

The pump station equipment controllers, which are Siemens PLCs, are connected to industrial smart gateways.These gateways enable real-time collection of equipment status and process parameters and transmit them to the DCS server via 4G wireless networks.The solution facilitates the conversion of PLC protocols to OPC UA protocols, providing the management system with remote monitoring, alarm, management, control, and configuration analysis functions, thereby enhancing work efficiency and management levels.

Implemented Functions

Real-time Data Acquisition
The industrial smart gateways boast strong compatibility and efficient data processing capabilities, seamlessly interfacing with Siemens PLCs.They accurately and frequently collect switch data (such as operation and fault statuses) and analog data (such as current and liquid level parameters) from pump station equipment, laying a solid data foundation for monitoring and analysis.

Remote Monitoring and Visualization
After transmitting the data to the DCS server via 4G wireless networks, the management system enables remote real-time monitoring.Managers can intuitively view equipment operation screens, real-time parameters, and their changing trends.The data is also visually presented in the form of charts, reports, and curves.

Intelligent Alarm and Early Warning
The system establishes an intelligent alarm and early warning mechanism.When data exceeds specified ranges or equipment abnormalities occur, alarm information is immediately and prominently displayed on the monitoring interface and pushed through multiple channels such as SMS and email.It can also predict equipment failures or performance degradation trends in advance through historical data analysis.

Remote Control Operations
The solution supports remote control of valve start-stop operations by managers through the DCS system, enabling flexible adjustments to pump station process flows.This improves operational convenience and efficiency while reducing the workload and safety risks for on-site personnel.Strict permission management and security authentication are enforced for all operations.

Configuration Analysis and Optimization
Managers can freely configure monitoring interfaces and customize personalized screens. The system also possesses in-depth data analysis capabilities, allowing it to uncover data patterns and potential issues, providing a scientific basis for optimizing equipment operation, enhancing operational efficiency, reducing energy consumption, and extending equipment lifespan.
