LoRa Indoor Personnel Tracking Solution for Smart Factories, Mines and Worker Safety

Factories, mines, warehouses, hospitals, construction sites and industrial parks need more than conventional employee ID cards. Managers may need to know where workers are located, whether someone has entered a dangerous zone and where an emergency alarm was triggered.

Shenzhen Jinshengchang Technology Co., Ltd. provides a complete LoRa indoor personnel tracking solution consisting of smart personnel badges, Bluetooth positioning nodes, LoRaWAN gateways, the lora8 management platform, mobile applications and system-integration interfaces.

The core wearable device can be configured as a LoRaWAN badge tracker that combines employee identification, indoor location recognition, low-power communication and one-touch SOS alarms.

Why Use LoRa for Indoor Personnel Tracking?

GPS signals are normally weak or unavailable inside factories, warehouses, underground facilities and multi-floor buildings. LoRa does not directly replace an indoor positioning technology. Its main role is to transmit identity, location-zone, battery and alarm information over a long-range, low-power network.

Indoor location can be determined using:

• BLE beacons for room- or zone-level positioning;
• Bluetooth AOA for higher-accuracy indoor positioning;
• UWB for high-precision critical areas;
• Wi-Fi scanning for approximate location recognition;
• RFID or NFC for checkpoints and identification;
• GNSS for outdoor parts of the same industrial site.

The badge can scan or interact with the selected positioning infrastructure and transmit the resulting location data through LoRaWAN.

Complete System Architecture

A typical solution consists of:

Personnel Badge → BLE/AOA/UWB Positioning → LoRaWAN Gateway → Ethernet, Wi-Fi or 4G → lora8 Platform → Web/APP/API

Each badge is linked to a worker, contractor or visitor. The system can therefore associate every SOS alarm and location event with an identified person.

Core components

1. Personnel tracking badge: LoRaWAN, BLE, SOS, motion sensor and optional GNSS, NFC, Wi-Fi or UWB.
2. Positioning nodes: BLE beacons, AOA locators, UWB anchors or RFID checkpoints.
3. LoRaWAN gateways: Receive badge data and forward it to a server.
4. lora8 platform: Manages personnel, locations, devices, alarms and reports.
5. Mobile applications: Provide remote alarm and location access.
6. API and SDK: Connect the system to customer software.

Main Functions

Indoor Personnel Location

The platform can display the worker’s building, floor, room, production area or other identified zone. Higher-accuracy coordinates can be provided when Bluetooth AOA or UWB infrastructure is selected.

One-Touch SOS Alarm

A worker can press the physical SOS button during an injury, equipment failure, fire, security incident or medical emergency.

The alarm can contain:

• Employee name or ID;
• Badge number;
• Latest valid location;
• Alarm time;
• Battery status;
• Device status;
• Incident-processing status.

Long-press, repeated-press and alarm-cancellation rules can be customized to reduce accidental activation.

Electronic Geofencing

Managers can define restricted and authorized areas. The platform can generate an alert when a worker:

• Enters a dangerous zone;
• Leaves an assigned work area;
• Remains too long in a restricted location;
• Enters an area without authorization;
• Does not arrive at an evacuation assembly point.

Fall and Man-Down Detection

An optional accelerometer can detect falls, impacts, long inactivity or abnormal movement. Thresholds must be tested in the actual workplace because climbing, running, machine vibration and normal work activities may otherwise create false alarms.

Historical Routes and Reports

The platform can store movement events, zone-entry records, SOS alarms and alarm-processing history. Reports may support safety reviews, incident investigation and workforce management.

Emergency Evacuation

During an emergency, supervisors can review personnel distribution, last known locations and arrival at designated assembly zones. The system supports emergency decisions but should not be treated as the only evacuation-control method.

Technical Configuration

Actual positioning accuracy, communication coverage and battery life depend on the selected technologies, node density, building structure, reporting interval and hardware configuration.

Deployment in Different Environments

Factories and Warehouses

Metal machinery, storage racks, walls and moving goods can affect radio propagation. Beacons should be installed at entrances, corridor intersections, workshops, warehouses and dangerous areas. Gateway coverage must be verified after machinery and inventory are in their normal positions.

Mines and Underground Facilities

Underground projects may require multiple gateways, backup power, offline data storage and gateway-disconnection alarms. Positioning nodes should be installed along tunnels, work areas, entrances and evacuation routes.

Multi-Floor Buildings

Every floor should use a unique location identifier. Beacons or anchors should be positioned near stairs, elevators, corridors and important rooms to reduce floor-identification errors.

Outdoor and Indoor Industrial Parks

A hybrid badge can use BLE, AOA or UWB inside buildings and GNSS outdoors. LoRaWAN or 4G can transmit data across the wider industrial campus.

lora8 Personnel Safety Platform

The lora8 platform can provide:

• Real-time personnel and zone display;
• Multi-site and multi-floor maps;
• Employee-to-badge binding;
• SOS alarm pop-ups;
• Audible and visual notifications;
• Electronic geofences;

Recommended Deployment Process

1. Analyze the building layout and safety requirements.
2. Define room-, zone- or coordinate-level accuracy.
3. Select BLE, AOA or UWB positioning.
4. Confirm the regional LoRaWAN frequency.
5. Design beacon, anchor and gateway locations.
6. Install a pilot system in representative areas.
7. Test positioning, alarm latency and coverage.
8. Adjust thresholds and infrastructure locations.
9. Train administrators and emergency teams.
10. Expand the system after pilot verification.

The number of beacons and gateways cannot be calculated from floor area alone. Wall materials, ceiling height, metal obstacles, floors, device quantity and transmission intervals must also be evaluated.

Frequently Asked Questions

Can LoRaWAN alone provide precise indoor positioning?

No. LoRaWAN primarily transmits data. BLE, Bluetooth AOA, UWB, Wi-Fi or another positioning layer is required to determine indoor location.

Can one badge work indoors and outdoors?

Yes. A hybrid badge can use indoor positioning technologies inside buildings and GNSS outdoors.

Can the badge send an SOS alarm?

Yes. A physical SOS button can transmit the worker’s ID, latest location, time and device status to the platform.

Can the system detect a fall?

Optional motion sensors can support fall or man-down detection. The algorithm must be tested and adjusted for the workplace.

Can Jinshengchang connect the system to existing software?

Yes. API, SDK, webhook, MQTT, TCP/UDP, HTTP and customized protocols can be discussed.

Is private-server deployment available?

Yes. Cloud deployment and private-server deployment can be configured according to project requirements.
