Household alarm solution for residential areas

Background
With accelerating urbanization, the number of households using natural gas in residential communities continues to rise. To ensure resident safety, gas alarms must be installed in every home and connected to an IoT platform for real-time monitoring, remote management, and early warning capabilities.

Solution Workflow

1. Gas Alarm Installation
   Deploy reliable gas alarms in each household, capable of accurately detecting hazardous gas leaks (e.g., natural gas, carbon monoxide).

2. IoT Platform Integration
   Connect all gas alarms to the IoT platform via NB-IoT wireless communication.

3. Data Transmission & Processing
   When detecting gas leaks, alarms trigger warning signals transmitted to the cloud through the IoT platform:

   • Alarm Activation: Detected leaks initiate automatic gas valve shutdown via linked devices.

   • Data Relay: The IoT platform forwards alerts to cloud servers.

   • Storage & Management: Cloud servers process/store data while enabling query, statistical, and management functions.

4. Early Warning & 通知
   Cloud-based real-time analytics trigger automated alerts when leaks exceed safety thresholds:

   • SMS Alerts: Notifications sent to residents’ mobile phones

   • Voice Calls: Automated voice warnings delivered via call systems

Key Advantages

• Real-Time Monitoring: Instant leak detection mitigates potential hazards

• Remote Management: Configure parameters and check statuses via IoT platform

Supplementary Functions

1. 1. Single or multi-residence monitoring through NB-IoT connectivity, accessible via PC/mobile/iPad.

   2. Community-wide centralized monitoring: All alarms connect via NB-IoT to a centralized monitoring hub.
