Customer Challenge

Lack of Unit-Level Energy Measurement
  • No independent measurement of electricity and compressed air across workshops and products, making unit energy consumption untraceable.
Insufficient Safety Management in Power Distribution Rooms
  • Distributed power rooms face fire, water leakage, and unauthorized access risks, with inspections relying on manual work only.
Unmonitored and Inefficient Compressed Air System
  • Aging pipelines lead to leakage rates exceeding 15%, with no real-time monitoring in place.
No Unified Energy Data Platform
  • Energy data is fragmented, with no centralized platform to support visibility, analysis, or decision-making.

What We Implemented

Factory-wide Sub-metering System for Power Distribution
  • Sub-metering is deployed across distribution circuits and key process equipment, establishing a plant-wide energy data acquisition system.
Online Environmental Monitoring for Power Distribution Rooms
  • Remote sensors are installed in distribution rooms to monitor smoke, temperature, humidity, and water leakage, replacing manual inspections.
Compressed Air Monitoring and Leakage Analysis
  • Pressure and flow sensors are deployed across four compressed air systems to monitor usage and identify leakage within the network.

System Architecture

A structured three-layer architecture connecting data acquisition, measurement, and platform-level analysis for reliable energy monitoring and system operation.

Platform Layer
  • Hosts the energy management system, enabling data storage, visualization, and analysis.
Acquisition Layer
  • Collects and aggregates data from field devices, ensuring unified system access.
Measurement Layer
  • Measures energy consumption and environmental parameters across equipment and facilities.

  • Unit energy consumption per product becomes measurable.
  • Clear energy responsibility across workshops.
  • Data becomes traceable, comparable, and analyzable.

 

Compressed Air Efficiency Improved with Leakage Control

How it works
  • Pressure and flow sensors are deployed across the compressed air system to monitor usage and establish correlations between workshop consumption, energy use, and air demand, while identifying leakage points.
What you get
  • Leakage detected through real-time monitoring (from >15% to <5% after optimization).
  • Clear usage boundaries between workshops.
  • Data foundation for system optimization and energy-saving actions.

 

Safer and Smarter Power Distribution Room Management

How it works
