The "Yixing CNG (Compressed Natural Gas) Station Automatic Control System" consists of a computer human-machine interface interaction (HMI) system, a PLC data acquisition and monitoring system, a fire and gas alarm system, an ESD emergency shutdown system, a digital network, and a communication system. The RTU/PLC real-time collects the operating parameters of process equipment such as the unloading column, compressor, and gas seller, and performs local display, automatic data statistics management and query, automatic control, remote control, interlock control, and over limit alarm. Real time data is uploaded to the CNG mother station and higher-level department computer management system through fiber optic/ADSL/GPRS communication.

The "Yixing CNG (Compressed Natural Gas) Station Automatic Control System" applies scientific automation management methods to achieve unified scheduling and management of gas supply. The entire system has an open data interface that can provide relevant data to user units. The CNG mother station and sub station systems also have video surveillance and infrared monitoring of illegal intrusion alarms around the station, providing a safety guarantee for on-site production. The system has extremely high reliability and stability, and has a high cost performance ratio.
