Application of Real-Time Location System (RTLS) & Safety Alert System in Manufacturing Plants
02/12/2025
1. Background
Located in an industrial zone in South Korea, the large-scale manufacturing plant with more than 1,000 workers operates continuous production lines in an environment with various potential hazards such as high-speed machinery, high temperatures, blind spots, and intense noise levels.
The factory management aims to upgrade its safety monitoring and early-warning infrastructure, moving toward the standards of a Smart Factory—where technology plays a central role in protecting people and optimizing operations.
2. Factory Challenges
Despite having a centralized monitoring system, the factory still faces multiple issues:
- Inability to monitor workers’ locations and statuses in real time
- Slow detection of emergency situations such as falls, unconsciousness, or loss of movement
- Delayed response due to lack of timely alerts
- Heavy dependence on human supervision
- Complex working environment: signal interference, many blind-spot areas
3. Factory Expectations
The company wants to deploy a system that can:
- Continuously and accurately track worker locations
- Provide automatic alerts in hazardous situations
- Support small-scale pilot deployment and easy expansion factory-wide
- Use rugged devices that operate stably and are easy to install and maintain
- Combine location tracking with attendance and workforce management
