MK3 locators plus GWO04 outdoor gateways: draw geo-fences freely on the platform map. When a person crosses the boundary, the platform raises an alert and the locator plays an on-site voice prompt at the same time — the control room sees it and the visitor hears it.
Mountains, lakes and woodland overlap. Manual patrols and PA announcements neither watch the boundary nor stop anyone in time.
Undeveloped slopes, cliff edges and closed construction zones rely on signs; crossings go unnoticed.
Valleys, dense forest and tunnel mouths often have no 4G, so 4G-only trackers drop their position data.
Control-room findings are relayed over radios, while the visitor hears nothing and the moment for intervention is lost.
Study tours, hiking groups and senior groups are counted by roll call; one missing person means a wide, slow search.
MK3 answers "where is the person and can we reach them"; GWO04 handles uplink and downlink; the platform defines the fence and fires the alerts.
Visitors and staff wear an MK3 locator. Outdoors it uses GPS / BeiDou, indoors and at attractions BLE beacons can be added; positions are sent over LoRa.
GWO04 outdoor LoRaWAN gateways on summits, at visitor centres and cable-car stations aggregate all terminal data and deliver voice-prompt commands back down.
Uplink: MK3 → LoRa → GWO04 → Platform. Downlink: Platform → GWO04 → MK3 voice prompt.
No public network and no large-scale cabling — plan gateway by gateway against coverage and capacity.
Mount GWO04 at visitor centres, cable-car stations and ridge tops; plan ~1 km coverage radius in open terrain.
Trace polygons for visitor, hazard and construction zones; each can be active only during set time slots.
Bind MK3 to a visitor or group on issue and collect on exit; staff can wear them permanently in their own group.
Voice messages are factory pre-loaded on the MK3 and cannot be configured or customised on the platform. A locator must be inside gateway coverage to receive downlink commands — add gateways or repeaters in blind spots.
MK3 sends GPS / BeiDou positions over LoRa at the configured interval
GWO04 receives and aggregates terminal data, then forwards it to the platform
The platform checks the polygon, time slot and dwell conditions
Pop-up / sound / SMS to duty staff, with person, time and position logged
A downlink command reaches that MK3, which tells the visitor to return to the safe zone
Off-the-shelf MK3 locators and GWO04 gateways, combined without custom development.
Draw polygons or circles for allowed and restricted zones, each active by time slot and personnel group.
A crossing fires pop-ups, sounds and SMS / call notifications to duty staff, with automatic logging.
At the same moment, a LoRa downlink command triggers the MK3's built-in pre-loaded voice message on site. Prompt content is not configurable.
Every person on one map; count groups quickly and locate anyone who has fallen behind.
Track playback and dwell-time statistics to optimise routes and transport capacity.
One-button SOS with position; alert the nearest duty point and narrow the search area from the last fix.
Boundary alerts always use both the platform channel and the locator voice channel.
| Alert type | Trigger | Level | Action |
|---|---|---|---|
| Geo-fence crossing | Position leaves the permitted visitor zone | Critical | Platform pop-up / SMS + MK3 voice prompt to return |
| Restricted area entry | Cliff edge, water, closed construction zone | Critical | Platform alert + repeated locator voice warning, notify nearest patrol |
| SOS | MK3 SOS button pressed | Critical | Pop-up with position, SMS / call, start search and rescue |
| Excessive dwell | Stay in a hazard zone beyond the set time | Major | Platform alert and log, trigger on-site verification |
| Abnormal stillness | No position change for a long period | Major | Duty staff call to verify, dispatch if needed |
| Device offline | No data from a locator within the timeout | Info | Check coverage or hardware to avoid false "online" status |
| Low battery | Battery below threshold | Info | Remind staff to collect and recharge for all-day coverage |
Change a polygon instead of moving a single sign — temporary closures take effect immediately.
Platform alert and locator voice fire together, so visitors hear the warning without human relay.
LoRa private-network backhaul keeps positions flowing in valleys and forests without 4G.
Two standard products, no custom development, short deployment cycle.
Parallel gateways and dynamic terminal channels absorb peak-season visitor growth.
The platform can run on-premise so visitor location data never leaves the park.
Keep visitors out of undeveloped slopes and cliff edges with instant alerts and voice warnings.
Large woodlands with no fixed boundary — fence the trails and count groups as they move.
Zone control by time slot, back-of-house exclusion, track playback and dwell-time analysis.
Bind groups, detect stragglers automatically and narrow search areas with SOS positions.
