On/Off-Duty Intelligent Management System
Smart Badge + Bluetooth Beacon + Indoor LoRa Gateway

In factories and office buildings, whether an employee is on duty or how long they have been away has long been a blind spot in management. This solution equips each employee with a smart badge, deploys Bluetooth beacons in every room, and aggregates data through indoor LoRa gateways—delivering real-time visibility of on-duty status, automatic tallying of off-duty duration, and room-level indoor geo-fencing.

01 · Management Pain Points

Invisible on-duty status and unclear off-duty duration

🤷

Traditional manual roll calls and checks are costly, coarse-grained, and prone to disputes

Guessing whether someone is on duty

⏱️

A team leader only learns who is on duty after a round of inspection; managers have no visibility when office staff leave for meetings or personal errands.

Off-duty duration is a muddle

🏢

Ten minutes or two hours off duty? Without objective data, performance review lacks a basis, and tracing personnel location after a safety incident is difficult.

Indoor GPS fails completely

02 · Technical Principle

One beacon per room; the badge “listens” to locate

Working method:How it works:470MHz LoRaEach room is fitted with 1 Bluetooth beacon that continuously broadcasts its location identity; the badge keeps scanning nearby beacons and sends “I am near Beacon ①” (i.e., “I am in Workshop A”) together with the badge ID viato the indoor gateway, which then uploads to the platform via 4G/Ethernet.For areas requiring high precision(e.g., hazardous work zones, valuable-asset rooms), multiple beacons are deployed in one room and RSSI tri-lateration achievesMeter-level positioning

, and defines fine-grained indoor fencing.

03 · Deployment Options

Room-level or meter-level, freely chosen by management granularity

No need to go fine-grained overnight—launch room-level first, then densify key areas

📍 Room-level Positioning

One beacon per room · know “which room a person is in”
Deploy 1 Bluetooth beacon per room for minimal installation work
The badge scans the strongest beacon to determine the room it is in
Full visibility of on-duty/off-duty status, which room, and entry/exit times

Battery-powered beacons last several years with virtually zero maintenance

High precision

🎯 Meter-level tri-lateration + indoor fencing

Meter-level accuracy
Deploy 3 or more beacons in a single room for tri-lateration positioningAccuracy up to1–3 m
, supporting workstation-level management
Indoor electronic fencing: entry/exit/prolonged-stay timeout triggers alerts instantly

Can be mixed with room-level deployment, focusing investment on key areas

💡 Recommendation: deploy conventional areas by “one beacon per room”, and densify hazardous/key areas with tri-lateration—spend the budget where it matters most.

04 · System Architecture

Four-layer data link, from workstation to management dashboard

Link description:Link description:470MHz LoRaThe badge continuously scans Bluetooth beacons inside the room, resolves its location identity, and sends via

a single hop directly to the indoor gateway (strong wall penetration; 1–2 gateways per floor cover the whole building); the gateway aggregates and uploads to the cloud via 4G/Ethernet. Throughout, the badge only needs to “scan + send a short message”, consuming very little power—one charge lasts weeks.

06 · Platform Features

🗺️

From “checking attendance” to “data-driven management”

On-duty map

⏱️

Floor plan shows in real time which room each person is in, with colors distinguishing on-duty/off-duty/away.

Off-duty duration statistics

🚨

Automatically records each person's entry/exit time for every room; off-duty start/end and cumulative duration are tallied automatically.

Off-duty timeout alert

📊

When key-post personnel leave beyond a set duration, the system instantly notifies the team leader/responsible person.

Attendance & man-hour reports

🚧

Auto-summarized by person/team/day/month, giving an evidence basis for attendance assessment.

Indoor electronic fencing

🧭

Virtual boundaries for hazardous and valuable-asset zones; entry/prolonged stay/unauthorized leaving trigger instant alerts.

Trajectory replay & traceability

Replay any person's trajectory over any period; safety incidents and accountability are traceable.
