Workers wear hard-hat positioning terminals (hat cards) for real-time positioning at 1–2 m accuracy, combined with Bluetooth wristbands for real-time monitoring of body temperature, heart rate and other health parameters. Offering flexible LoRa/4G dual-version networking, with the platform integrating work-permit management, electronic fencing and multi-dimensional alarms to fully meet smart construction-site regulatory requirements.
Too many workers to manage, and people cannot be located when something happens
Construction sites have high worker turnover and mixed crews; who is on-site, who is in a hazardous area, and how many are at each work face cannot be managed by roll call and visual inspection alone.
Deep foundations, edges, blasting zones and other hazardous areas lack technical controls, so unauthorized entry or lingering cannot be detected and warned in time.
When a worker falls suddenly ill or is in danger, location and rescue cannot be obtained immediately; high-temperature work health risks (heat stroke, etc.) lack pre-event monitoring.
Same hard-hat positioning terminal, two backhaul methods, adapting to different sites
Wristband → hat card → base station/4G → platform; health data rides along with positioning for backhaul
Hard-Hat Positioning Terminal + Bluetooth Health Wristband + LoRa Base Station (LoRa version)




Tailor-made for smart construction sites, ready to use out of the box
Worker presses the hat card SOS key for instant reporting; platform popup + located position, linking nearby rescue
Hot-work, high-altitude, confined-space and other work permits applied and approved online, verified in conjunction with personnel positioning
Hazardous and work areas electronically delimited; real-time alarm on personnel crossing or straying in
Real-time dashboard of body temperature and heart rate; automatic warning beyond thresholds, preventing heat stroke and sudden illness
Automatic check-in/check-out records; attendance and man-hour reports generated by team and area
All personnel positions shown on one map, filterable by team/area, with history tracks replayable anytime
Pre-warning + in-process alarm + post-incident tracing, tiered push with nothing missed
| Alarm Type | Trigger Condition | Level | Disposition Method |
|---|---|---|---|
| 🚐 SOS Help | Worker presses the hat card SOS button | Emergency | Platform popup + SMS/App push, location showing the incident site |
| ❤️ Abnormal Heart Rate | Wristband heart rate exceeds safe threshold | Emergency | Push to team leader and safety officer, verify and handle by phone |
| 🌡️ Abnormal Body Temperature | Body temperature exceeds the set threshold | Important | Warn of heat-stroke risk, prompt rotation and rest |
| 🚧 Crossing/Intrusion | Personnel enters a hazardous-area electronic fence | Emergency | Hat card voice on-site reminder + platform alarm |
| ⏸️ Prolonged Stillness | Personnel remains still beyond the set duration | Important | Suspected fainting/trapped, notify safety officer for on-site check |
| 🔌 Low-Battery Reminder | Hat card battery below threshold | Notice | Remind to replace/charge, avoiding positioning blind spots |
| 📴 Offline Alarm | Hat card has not reported for a long time | Important | Device fault or manual shutdown, check immediately |
Meter-level accuracy down to work face/station, meeting refined management
