I. System Architecture

1. Text Description

The system adopts a three-layer architecture: Perception Layer, Control Layer, and Application Layer.

• Perception Layer
  • Flexible SBR Fabric Sensor: Embedded in seats or mattresses to collect signals such as posture, body movement, bed exit status, and respiration.
  • NTC Temperature Sensors: Arranged at multiple points on the heating pad surface for real‑time temperature monitoring.
  • Environmental Sensors (optional): Temperature, humidity, and light sensors for adaptive control.
• Control Layer
  • Signal Conditioning Circuit: Amplification, filtering, and analog‑to‑digital conversion.
  • Microcontroller Unit (MCU): Runs embedded algorithms to process sensor data, execute PID temperature control, and detect abnormal events.
  • Drive Circuit: MOSFET or relays to control the power supply to the graphene heating pad.
  • Communication Module: Wi‑Fi / Bluetooth / LoRa / 4G for uploading data to the cloud and receiving remote commands.
• Application Layer
  • Cloud IoT Platform: Device management, data storage, and rule engine (e.g., bed‑exit alarm, automatic heating).
  • Mobile App / Mini‑Program: Provides real‑time status, push notifications, and remote temperature adjustment for family members or caregivers.
  • Institution Management Dashboard: Centralized monitoring for multiple beds, energy consumption statistics, alarm logs, and report export.

As the world shifts toward renewable energy, solar technology has evolved from industrial equipment into everyday essentials. Two brands born in 2007—BigBlue and Letsolar—have each carved out a unique space in this growing market. With a focus on high-performance portable power and scalable solar solutions, they offer products that cater to outdoor enthusiasts, emergency preppers, and eco-conscious households alike.
