1. Regulatory Authorities' Smart Platform
Policy-driven: The 2021 revision of the New Work Safety Law mandates the installation of combustible gas alarm devices in industries such as catering.
Security Status:
● The major gas explosion accident in Shibei North City: 26 deaths and 138 injuries
● The particularly severe accident at the Ningxia Yinchuan barbecue restaurant resulted in 31 deaths and 7 injuries.
● In 2022, liquefied gas accidents accounted for 56.1% of all incidents, with casualties representing 61.3%.
Platform Features:
● Centralized Device Operation Monitoring (Web/APP/WeChat/SMS)
● Real-time Alarm Notification and Response Tracking
● Big Data Analysis and Early Warning
● Overall Overview of Gas Safety Conditions at the City Level
2.Household Gas Safety (Natural Gas via Pipeline)
system architecture ：
● New electromagnetic valves, intelligent safety valves, and home alarms are wirelessly connected via Sub-1G technology.
● The alarm detects an abnormality → triggers an alert → the system automatically cuts off the gas supply via wireless linkage.
● Report an incident via a mini-program, SMS, or voice notification
● The data is uploaded to the IoT monitoring platform via 4G/NB networks.
3. Household Gas Safety (bottled liquefied gas)
system architecture ：
● The intelligent liquefied gas pressure regulator, dry burn alarm, and household alarm are wirelessly connected.
● The alarm detects an abnormality → triggers an alert → the system automatically cuts off the gas supply via wireless linkage.
4. Household gas detector product system
Complies with GB15322.2-2019 standards and CCC requirements, supporting multiple communication protocols (e.g., NB-IoT, 4G, LoRa, Sub1G).
