Application Scenario

At a large architectural ceramic production base, multiple spray dryers and kiln production lines operate around the clock. Environmental protection authorities require that monitoring data from exhaust outlets—such as particulate matter, sulfur dioxide, nitrogen oxides, and VOCs—be reported to the provincial environmental monitoring platform (HJ212 platform) in real time and accurately. At the end of each month, staff are required to manually read meters, compile monitoring data and total pollutant discharge reports, and submit written documentation to ensure compliance with pollutant discharge permit requirements.

Challenges

The traditional manual meter reading and reporting process is not only inefficient but also fails to capture emission fluctuations outside of working hours due to the continuous nature of ceramic production. This often leads to missing data or delayed reporting, which may result in additional penalties due to untimely responses. Furthermore, without a detailed log of original monitoring data, it is difficult to trace data entry errors or potential tampering, making it impossible to meet full-chain traceability and regulatory requirements—thus increasing operational risks for the company.

Solution

To address these issues, WideIOT offers a solution centered around an environmental data collection gateway. This gateway can connect to devices such as flue gas monitors, gas flow meters, and VOC analyzers, collecting real-time data on exhaust gas concentrations, pollutant discharge volumes, VOC components, and more. The data is then formatted according to the HJ212 protocol and reported to the provincial environmental monitoring platform via 4G network. This enables real-time data reporting, automatic anomaly alerts, statistical reporting and analysis, and traceable logs—significantly improving the digital and intelligent management of environmental compliance.

Key Features

1. Comprehensive Data Collection

The gateway can collect data from PLCs, instruments, sensors, and other devices, including particulate matter, sulfur dioxide, nitrogen oxides, and other exhaust pollutant concentrations, as well as operational parameters such as flow rate, temperature, and pressure. This enables integrated collection of production and emission data.

2. HJ212 Protocol Compliance

The gateway supports protocol conversion and strictly follows the HJ212 standard for data packaging, validation, and encrypted transmission. It automatically handles scheduled data reporting and active reporting of abnormal data, ensuring that the reported data format is compliant and ready for environmental supervision.

3. Customizable Alerts

Flexible alert rules can be configured. When particulate matter or nitrogen oxide levels approach or exceed thresholds, the system immediately sends alerts via SMS, WeChat, email, or other channels—giving the company time to take corrective action and reduce pollution in a timely manner.

4. Reliable Data Transmission

With features such as multi-link redundancy, local data caching, and resume from breakpoint, the gateway effectively addresses issues like data packet loss, disconnections, and missed reports. It ensures 24/7 uninterrupted data transmission, guaranteeing the integrity and reliability of data received by the environmental authority's platform.

5. Remote Management and Traceability

Each gateway is assigned a unique device ID and connected to a centralized management platform. Administrators can remotely configure parameters, diagnose faults, and trace logs. When anomalies occur, issues can be quickly identified and addressed, ensuring compliance with legal and operational standards.
