Online Monitoring Solution for Large Units_Shenzhen Qianhai IntelliUnion Technology Development Co., Lt

Online Monitoring Solution for Large Units

Large thermal power units operate continuously at high temperature, pressure and speed, making components prone to wear and deterioration. Strong interdependencies allow local faults to cascade, while traditional inspections and scheduled maintenance provide delayed monitoring and inadequate warnings. IntelliUnion's intelligent O&M uses industrial acquisition and analysis equipment with modular plug-in cards for critical-unit vibration and process signals. Ultra-high-precision acquisition, intelligent modes, early warning and big-data self-diagnosis establish comprehensive lifecycle monitoring and health management. Condition sensing, intelligent analysis, warnings, precise diagnosis and predictive maintenance shift operations from reactive/scheduled repairs to condition-based and predictive maintenance, ensuring safe, stable and efficient long-term operation.

Monitoring Challenges

Manual Inspections and Insufficient Monitoring Dimensions

Manual checks and experience produce discontinuous, delayed data that misses early risks. Monitoring only vibration, temperature and a few other parameters without multidimensional fusion captures incomplete fault signatures and reduces diagnostic accuracy.

Severe Data Silos and No Unified Analysis Platform

DCS, PLC and inspection systems are disconnected, preventing joint analysis and a comprehensive health view. Fault assessment depends heavily on senior engineers, without standardized models or knowledge bases.

Weak Warnings and Reactive Maintenance

Simple thresholds without intelligent models or trend analysis delay anomaly identification and generate many ineffective alarms. Scheduled maintenance and emergency repairs result in both over- and under-maintenance, risking unplanned downtime and production safety.

Closed Systems and Unsupported Maintenance Decisions

Closed interfaces and inconsistent protocols prevent integration with intelligent O&M and digital twin platforms. Without deterioration and remaining-life assessment, maintenance timing and spare-parts stocking depend on experience, keeping costs high.

Product Advantages

Multi-Channel Acquisition of All Parameters

Fully parallel, synchronized channels with differential inputs and electrical isolation provide stable, interference-resistant data. Vibration, displacement, temperature, process and electrical signals are integrated for comprehensive monitoring.

Early Fault Detection and Accurate Localization

An intelligent diagnostic model library combines envelope analysis, spectral demodulation and trend prediction to extract fault features and calculate weights automatically. It accurately identifies bearing wear, rotor unbalance and insulation defects, providing advance warning and substantially reducing false and missed alarms.

Comprehensive Visualization

Waveforms, spectra, trends, bar charts and 3D digital twins display health, alarm levels, fault locations and development trends, enabling real-time visibility, historical traceability and anomaly replay for efficient management and decisions.

Intelligent Diagnosis and Convenient Remote Access

Built-in fault and diagnostic rule libraries convert expert experience into standardized, reusable capabilities for consistent diagnosis and response. Browser/server architecture requires no client installation and supports computers, tablets and phones for remote monitoring, diagnosis and maintenance, meeting centralized, minimally staffed operation needs.
