Based on LoRa spread spectrum technology, coverage up to 1~5km (depending on environment). Suitable for underground mines, large construction sites, and other wide-area scenarios. No cellular network dependency for stable data transmission and position reporting. Strong penetration, effectively covering obstructed areas.
High-precision GPS positioning module, supporting real-time trajectory tracking and historical trajectory replay. Outdoor positioning accuracy ≤5m. Combined with LoRa backhaul, management personnel can monitor worker positions and movement paths at any time.
Built-in high-sensitivity vibration sensor, detecting falls, collisions, abnormal shaking and other dangerous actions. Automatically sends emergency alarm signals via LoRa when triggered. Backend pushes alerts instantly, ensuring first-time response to personnel safety events.
Light sensor continuously monitors ambient light changes, detecting abnormal lighting events (entering restricted areas, being covered/obscured), triggering light sensor alarms. Effectively prevents malicious covering of the badge or personnel entering dangerous dark zones.
The 802 badge features three physical buttons on the front with clearly defined functions: Button ① Clock-in, Button ② Clock-out, Button ③ Power on/off & SOS emergency alarm. No training required, one-key help in emergencies, ensuring zero-delay safety response.
Press Button ① to immediately upload clock-in records to the platform and confirm successful check-in. Combined with Bluetooth auto-check-in, forming dual attendance guarantee — active button confirmation + near-field seamless recording, zero attendance data gaps.
Press Button ② to upload clock-out records, confirming sign-off status. Separate clock-in/clock-out buttons avoid misoperation. Precise attendance time recording, tardiness and early departure一目了然, providing reliable data for payroll and work hour management.
Short press Button ③ to toggle power on/off; long press to trigger SOS emergency alarm, the badge immediately sends distress signals via LoRa with continuous position reporting. Dual-purpose one button, convenient daily power toggle, instant emergency help, saving lives at critical moments.
The 802 badge features a built-in BLE Bluetooth module, supporting near-field personnel sensing and interaction. Three functions — aggregation alarm, auto check-in, and mutual exclusion control — upgrade from passive positioning to active safety management, covering personnel aggregation risks, attendance efficiency, and area control scenarios.
When multiple badges aggregate beyond the set threshold (e.g., 3+ people in the same area exceeding timeout) within Bluetooth near-field range, an aggregation alarm is automatically triggered and reported to the platform. Suitable for restricted area personnel aggregation control, preventing excessive concentration in dangerous areas and reducing group safety accident risks.
When the badge approaches a Bluetooth beacon (deployed at entrances/attendance points), it automatically completes check-in without manual operation. Achieving seamless attendance — personnel passage equals recording, improving attendance accuracy and work efficiency, eliminating proxy check-in and missed check-in issues.
Based on Bluetooth near-field identification, when personnel from different permission groups enter the same area, mutual exclusion alarms are triggered. Example: construction workers and inspection personnel cannot simultaneously exist in dangerous operation zones — the system automatically alerts and notifies management to intervene, achieving area permission isolation and dynamic control.
