People and Technology has been awarded the contract to supply its IndoorPlus+ Solution for worker safety at the KOEN (Korea South-East Power Co.) Yeongheung Power Plant Units 3 and 4 underground tunnel, located 900 meters below ground. The agreement, finalized on November 19, marks a significant milestone as the solution will be deployed in an operational power plant rather than a construction site.

The IndoorPlus+ system will provide comprehensive safety management by enabling real-time worker monitoring, access control, and entry restriction to hazardous areas. This deployment ensures not only worker safety but also gives a clear, real-time view of on-site personnel and operations.

Advanced Safety Features of IndoorPlus+

As a market leader with the largest number of domestic references, People and Technology continues to set the de facto standard for IoT solutions in South Korea. The reliability and efficiency of the IndoorPlus+ Solution have been validated in numerous projects, and it has become a key player in the rapidly growing worker safety market.

For this project, the solution will include:

• BLE Tags on Safety Helmets:

  • Tags attached to workers’ helmets will track their real-time location within the underground site.
  • A proactive safety mechanism will prevent unauthorized entry into hazardous areas.

• Integration with External Sensors:

  • Proximity sensors to monitor access to restricted zones.
  • Remote gas detectors for critical gases such as carbon monoxide (CO), carbon dioxide (CO₂), hydrogen sulfide (H₂S), methane (CH₄), and oxygen (O₂) to ensure worker health and safety.

• Centralized Data Analysis and Visualization:

  • The IndoorPlus+ platform will collect, analyze, and display data from multiple external hardware systems, showcasing its ability to seamlessly integrate with diverse IoT devices.

Creating Value Through an Integrated IoT Platform

The integration of multiple systems into a single IoT platform highlights the unique value of the IndoorPlus+ Solution. By combining worker tracking with environmental monitoring, it delivers enhanced safety and operational efficiency.

This deployment underscores the importance of interoperability in IoT solutions, as IndoorPlus+ demonstrates its ability to act as the core platform for diverse external hardware, setting a benchmark for integrated safety solutions.

Looking Ahead

The successful deployment of IndoorPlus+ at Yeongheung Power Plant reaffirms People and Technology's position as a leader in IoT-driven worker safety solutions. As industries prioritize safety in hazardous environments, the IndoorPlus+ platform continues to prove its adaptability and effectiveness in addressing complex operational challenges.
