Personnel Safety & Positioning

1. Overview

Personnel Safety & Positioning Solution is an integrated IoT-based system designed to ensure the real-time safety, visibility, and management of workers across construction sites, industrial parks, mining operations, tunnels, power stations, and other high-risk working environments.

By combining UWB, LoRaWAN, 4G Cat.1, NB-IoT, BLE, and GNSS with wearable devices such as smart watches, ID badges, wristbands, and positioning tags, the system enables accurate indoor/outdoor tracking, safety monitoring, emergency alerts, and operational management.

This solution significantly reduces safety risks, improves emergency response efficiency, and enhances overall workforce management.

2. Key Challenges

• Workers scattered in wide and complex environments

• Difficulty tracking personnel in real time

• Limited visibility of high-risk zone entry

• Slow emergency response and accident confirmation

• Lack of unified indoor + outdoor positioning

• Manual sign-in / patrol systems are inaccurate and inefficient

• Need for automated safety monitoring (fall detection, heart rate, temperature, SOS)

The system solves these problems using IoT wearable technology and a cloud-based platform.

3. System Architecture

4. Recommended Devices

4.1 Wearable Type

5. Key Features

✔ Real-Time Positioning

• Indoor (UWB: 10–30 cm accuracy)

• Outdoor (GPS/BeiDou/LBS)

• Multi-mode seamless switching

✔ SOS Emergency Alarm

Workers can press the SOS key to trigger alerts:

• Platform pop-up

• SMS/push notification

• Automatic location sharing

✔ Fall Detection / Man-Down Detection

Smartwatch sensors identify falls or long-time inactivity and trigger alarms.

✔ High-risk Zone Monitoring

When a worker enters a dangerous zone:

• Instant alerts

• Automatic recording

• Access restriction available

✔ Health Monitoring

• Heart rate

• Body temperature

• Blood pressure

• Motion/pedometer

✔ Attendance & Patrol

• Automatic check-in

• Patrol route tracking

• Shift behavior analysis
