As the "Battle for Blue Skies" deepens and the "Dual Carbon" goals are pursued, air pollution control has transitioned from broad-stroke management to a more refined, scientific, and intelligent phase. Urban air quality monitoring stations serve as the "sentinels" of environmental oversight, tasked with real-time monitoring of conventional pollutants such as PM2.5, PM10, SO₂, NO₂, CO, and O₃, as well as specific pollutants including VOCs and greenhouse gases.

Currently, the number of automatic air quality monitoring stations across the country is growing rapidly, and urban monitoring networks are becoming increasingly dense. However, this rapid expansion has exacerbated conflicts with traditional operation and maintenance models—how can monitoring data be uploaded in real time and reliably? How can equipment faults be quickly detected and resolved? How can the massive amounts of collected data be effectively mined and utilized? Addressing these challenges urgently calls for an information-based, intelligent monitoring and management system.

To meet this need, WideIOT offers a highly efficient and reliable IoT solution based on industrial smart gateways and an IoT platform. By deploying industrial smart gateways at each air monitoring station and connecting them to various monitoring instruments, the system can collect real-time data on air quality, meteorological conditions, and station environment, and transmit it over 5G/4G networks to the IoT platform. This enables centralized remote monitoring, alerting, management, and statistical analysis across multiple air monitoring sites, providing comprehensive and accurate data to support urban air quality governance.

Key Functions

1. Diverse Device Connectivity  
The gateway is equipped with multiple serial ports, network ports, and I/O interfaces, enabling connection to a wide range of instruments, including:
- Standard six-parameter analyzers (PM2.5, PM10, SO₂, NO₂, CO, O₃)
- VOCs online monitors
- Particulate matter component analyzers
- Meteorological sensors (temperature, humidity, wind speed, wind direction, barometric pressure)
- Station environmental sensors (temperature, humidity, voltage, current, water leakage detection, etc.)

2. Centralized Monitoring and Online Management  
Real-time data is displayed on a visual IoT platform dashboard, allowing for centralized monitoring and online management of multiple air monitoring stations. Users can view the geographic distribution, operational status, real-time parameters, alert records, and maintenance information for each site, enabling flexible allocation of personnel and resources to ensure safe and reliable station operation.

3. Multi-Level Alerting with Proactive Notifications  
The system supports configurable multi-level alert rules. When monitored data exceeds preset thresholds or equipment anomalies are detected, alerts are automatically triggered and delivered in real time via WeChat, SMS, and email to designated responsible personnel. Each notification includes critical details such as the affected site, timestamp, and specific data readings, shifting the paradigm from "passive detection" to "proactive alerting."

4. Data Query, Analysis, and Regulatory Integration  
The platform supports multi-dimensional data retri and analysis by time (hourly, daily, monthly, yearly), region, and pollutant type. Additionally, the system complies with the HJ212 protocol for seamless data integration with environmental protection authority platforms, facilitating data sharing and enhancing regulatory efficiency and responsiveness.
