Smart Personnel Management · Solution 7

Plant-wide indoor & outdoor personnel positioning
Badge GPS + Bluetooth + Visitor Management

Building on Solution 6's indoor on-duty management: indoor LoRa gateways + outdoor LoRa base stations form a joint network, and badges upgrade to a “GPS + Bluetooth + LoRa” tri-mode, achieving seamless all-scenario positioning of personnel from workshop to plant roads and from buildings to storage yards; visitor management is added to restrict visitor activity zones and trigger real-time boundary-breach and prolonged-stay alerts.

Plant-wide Personnel Positioning — Scenario Illustration
01 · Management Pain Points

Indoors managed, but outdoors becomes a blind spot

A plant is an indoor + outdoor mixed scenario; a single method can't cover both

🏭🌳

Indoor and outdoor systems are fragmented

Bluetooth beacons in workshops can manage personnel, but once they step onto plant roads, storage yards, or parking lots, they lose contact and location data breaks.

🚪

Visitor management is virtually useless

Visitor registration relies on paper and manual watching; unauthorized entry into workshops/hazardous-chemical zones is hard to detect, leaving no evidence for accountability and high safety risk.

⏳

No awareness of boundary breach or prolonged stay

Personnel straying into hazardous zones or visitors lingering long in sensitive zones go unnoticed until too late, missing the best intervention window.

02 · Solution Evolution

From “indoor on-duty” to “plant-wide integrated”

Reuse Solution 6's foundation; swap/add gateways and upgrade badges for smooth expansion

Solution 6 · Indoor On-Duty Management 🪪 Badge (Bluetooth + LoRa) Indoor positioning only 📡 Indoor LoRa gateway × N Enclosed plant / office building Upgrade & expand Solution 7 · Plant-wide Indoor-Outdoor Integrated 🪪 Badge (GPS + Bluetooth + LoRa) Indoor + outdoor dual-mode positioning 📡 Indoor gateway + outdoor base station hybrid network Seamless plant-wide coverage 👤 Visitor badge · restricted zone Boundary breach / prolonged stay instant alert
Key upgrade points:① Badge addsGPS/BeiDou positioning; switches to satellite positioning when leaving the building; ② deploy in the plantOutdoor LoRa base station, forming a hybrid private network with the indoor gateway; ③ platform addsVisitor Management Module. The original Bluetooth beacons, indoor gateways, and platform architecture are all reused, minimizing incremental investment and delivering the fastest results.
03 · System Architecture

Indoor-outdoor hybrid network, one map for the whole plant

Badge tri-mode switching · indoor gateway + outdoor base station · unified platform aggregation

Indoor and outdoor positions are seamlessly stitched into “one map of the whole plant” on the same platform; a person's trajectory stays continuous from workshop to plant road.
04 · Dual-Mode Positioning

Indoors rely on Bluetooth, outdoors on GPS—complementary, no blind spots

🏢 Indoor positioning (Bluetooth beacon)

Workshops / office buildings / warehouses and other enclosed spaces
Workshop A · beacon Office · beacon 🪪 Room-level; key areas tri-point → meter-level
  • Reuses Solution 6's Bluetooth beacons and indoor gateway
  • Room-level accuracy, meter-level in key areas
  • GPS fails indoors, Bluetooth fills the gap
  • Stable and reliable through walls
Outdoor expansion

🌳 Outdoor positioning (GPS + base station)

Plant roads / storage yards / parking lots and other open areas
🪪 GPS positioning Satellite + LoRa 📶 Outdoor Base Station 470M backhaul
  • Badge has built-in GPS/BeiDou, positions directly in open areas
  • Backhauls via outdoor LoRa base station, no cellular signal needed
  • Outdoor base station covers all plant roads and storage yards
  • Same map and same account as indoor positioning
05 · Visitor Management

Visitors may enter, but cannot leave the designated zone

From registration to departure, fully controlled, instant report on breach

🚪 Full-lifecycle visitor control

Visitors wear a dedicated badge; the platform defines their allowed activity zone (electronic fence), and entry into hazardous or unauthorized zones triggers an immediate alert
