1. Multi-Bed Support & Sensor Pairing

• Scalability Range: Native support for concurrent monitoring of 4 to 50 beds per localized gateway node, scalable across multiple floors via distributed gateway clustering.

• Individual Sensor Pairing: Unique MAC address mapping and cryptographic pairing keys for each sensor pad (e.g., Anechoease AK310-3).

• Dynamic Assignment: Caregivers can dynamically assign or re-assign specific sensor IDs to specific room and bed numbers via the central console without rebooting the system.

2. Centralized Dashboard

• Real-Time Visualization: Unified grid-view UI displaying the live status of all paired beds simultaneously (Green = Normal/Dry/Occupied, Blue = Wet/Triggered, Yellow = Out of Bed/Sensor Disconnected, Grey = Offline/Unassigned).

• Telemetry Streaming: Sub-second latency updates via WebSockets or MQTT protocols from the central hub to the nursing station terminal.

• Battery & Signal Indicators: Visual counters tracking the remaining battery life (%) and RSSI signal strength (dBm) for every individual wireless sensor node.

3. Alert Logic & Configurable Notifications

• Notification Routing Tiers:

  1. Per-Bed Alerts: Sent directly to the primary assigned caregiver via the mobile app.

  2. Group Alerts: Sent to designated wing or floor teams via SMS and mobile push notifications if a primary alert is unacknowledged for >45 seconds.

  3. Facility-Wide Alerts: Critical fallback system broadcasting to all station terminals during emergency or mass-disconnect events.

• On-Site Escalation: Triggered relays to local physical audio-visual pillars (strobe light and variable-tone sirens) located at ward corridors and nursing hubs.

4. Institution-Grade Requirements

• Role-Based Access Control (RBAC): Admin (IT/Management), Shift Supervisor (Configuration & Assignment), and Caregiver (View & Acknowledge only) permission layers.

• Data Logging & Auditing: Immutable, timestamped logs capturing moisture trigger times, caregiver response times, and acknowledgment signatures for medical compliance auditing.

• Shift Handover Reports: Automated, printable PDF/CSV summaries generated at shift ends detailing total alarm incidents, average response times, and active maintenance flags.

• Nurse Call System Integration: Built-in dry-contact relay outputs and RJ11/RJ45 interface ports on the central hub to integrate seamlessly into existing legacy nurse call systems (e.g., Hillrom, Jeron).

5. Hardware Options & Architecture Description

• Bed Sensors: * Wireless Options: Zigbee 3.0 / BLE mesh sensor pads for flexible, cable-free deployment in standard resident rooms.

  • Wired Options: Shielded RJ12 wired sensor pads for high-interference environments or psychiatric wards requiring zero wireless emissions.

• Aggregation Hardware:

  • Local Central Hub: On-premise industrial edge computer running localized alert logic independent of internet availability.

  • Cloud Gateway: Secure MQTT-to-HTTPS cellular/ethernet bridge that streams aggregated facility metrics to a centralized cloud management platform.

6. Privacy, Reliability, and False-Alarm Reduction

• Data Privacy: All over-the-air sensor transmissions are encrypted via AES-128. Local networks utilize TLS 1.3 for data-in-transit, ensuring strict HIPAA/GDPR data compliance.

• Failover & Battery Backup: Central hubs feature an integrated LiFePO4 battery backup providing up to 12 hours of continuous offline monitoring during facility power outages.

• False-Alarm Mitigation: Multi-point resistance thresholds and integrated software debounce filters (adjustable 1–5 second verification delay) to filter out localized sweat or sudden movement artifacts.

7. Installation & Scalability Guidelines

• Deployment Mapping: Position central hubs centrally within a 30-meter radius of wireless sensor clusters. Employ Zigbee signal repeaters in corridors with heavy concrete or metal shielding.

• Step-by-Step Configuration:

  1. Mount the central hub/gateway adjacent to the primary nursing station network switch.

  2. Power on the hub and open the configuration portal to define floor maps and rooms.

  3. Activate individual sensor pads one by one, using the barcode scanner interface to pair the hardware UUID to the designated bed slot.

  4. Connect physical dry-contact relays to the facility's existing nurse call wall jacks.

• Hot-Swapping & Scalability: To expand beyond 50 beds, install an additional sub-gateway on the secondary network switch; the central dashboard will auto-discover and integrate the new nodes into the unified grid layout.
