In-cabin BLE beacons, out-cabin LoRa relays and on-deck LoRa base stations — real-time personnel position in ship cabins and narrow spaces, with controlled access, visible headcount and verified identity.
Enclosed cabins, signal shielding and crowded crews — manual sign-in is slow and blurry; headcount relies on shouting and guessing
Steel hulls severely block satellite signals; conventional trackers go blind inside, position lost.
Shipyards, shafts, tanks lack 4G/5G; data cannot be sent out, platform sees nothing.
Multiple trades cross-working in narrow cabins; unclear headcount and distribution raise risk.
Paper log at boarding/cabin entry; identity hard to verify, omissions unnoticed, no traceability.
BLE beacons as in-cabin landmarks, LoRa relays as out-cabin repeaters, LoRa base as deck aggregator — no public network needed
Inside the cabin, GB50 BLE beacons act as position landmarks; workers wear MK3 locators scanning beacons to resolve cabin-level position.
LoRa relays along out-cabin walkways chain-repeat; LoRa base stations on deck aggregate all data to cloud or local platform.
In-cabin beacons, out-cabin relays and deck base deployed in layers, unified on platform
Flexible with work face, no public network, easy to install
GB50 BLE beacons on cabin walls, 3~4 per cabin, location = ID
LoRa relays chain along out-cabin walkways/hatches, cross-cabin coverage
LoRa base on open deck, aggregates data, uplink / local platform
Cabin/boarding entry with identity verification and info notice terminal
Swipe identity at boarding/cabin entry, authorized only, auto-logged
Wear MK3, auto BLE beacon positioning, resolve cabin
Position data chain-relayed by out-cabin relays to deck base
Deck base aggregates all data, uplink to cloud or local platform
Headcount, distribution, identity in one screen, emergency ready
Four terminal types cooperate into a complete confined-space personnel positioning network
Real-time count and distribution per cabin, hatch, deck; dense/hazardous zones always visible
Swipe identity at boarding/cabin entry, authorized only, auto-logged, no unauthorized entry
Entry screen shows current in-cabin personnel, work notice and safety tips, reaching the front line
Hazardous cabin / no-entry zone fencing, intrusion alarm with on-site intervention
MK3 one-button SOS reports position, guide evacuation and roll-call by cabin on emergency
Cabin in/out and inter-cabin movement replay, accident analysis and accountability
| Alert Type | Trigger | Level | Action |
|---|---|---|---|
| SOS | MK3 SOS button | Critical | Popup + SMS/call to manager, with cabin |
| Hazard cabin entry | Enter no-entry/unauth cabin | Critical | Alarm + on-site broadcast/guard intervention |
| Cabin overcrowd | Cabin headcount over limit | Major | Suggest dispersal, avoid crowd/cross-work risk |
| Verify fail | Unauthorized tries to enter | Major | Gate block and log, notify security |
| Overstay | In cabin over time (per shift) | Major | Check stranded, trigger verification if abnormal |
| No-move | Position unchanged long | Major | Guard call verify, on-site check if needed |
| Offline | Locator no data timeout | Notice | Check device fault or out-net, avoid fake-online |
| Low battery | Battery below threshold | Notice | Remind charge/swap, keep online whole shift |
BLE beacons, cabin/zone clear, no more blind-in-cabin
LoRa self-network backhaul, works in yard/shaft without 4G
Dense/hazard zones visible anytime, gain golden time
Verify before boarding/cabin, no unauthorized, traceable
Private deployment, data can stay on-site, meets secrecy
Beacons/relays move fast with work face, plan once cover all
Cabin, multi-deck personnel positioning & identity verify
Confined vessel internal maintenance headcount & position
Underground confined-space patrol zone control
Enclosed hole, underground engineering in/out & distribution
