– Robust Design: All underground components are designed to be waterproof, dustproof, and shockproof, ensuring stable performance.

– Autonomous Control and Alarms: The system can independently identify hazards and control power shutdowns, featuring automatic alarms for gas and dust concentration limits.

– Advanced Signal Acquisition: Supports multi-channel and multi-mode sensor signal acquisition, receiving and executing various control commands from the upper computer.

– Comprehensive Functionality: Offers multiple functions including analog signal acquisition, switch signal acquisition, and display, with integrated management software for unified control of gas extraction and dust monitoring.

– Self-Diagnosis and Protection: Equipped with self-diagnosis and self-protection functions, the system monitors its own operation and fault status, achieving dual-machine hot backup to ensure data security.

– Effectiveness Analysis: Provides pre-extraction effect analysis results for work faces and various extraction evaluation units, dynamically monitoring the effectiveness of gas extraction. This data serves as the foundation for gas extraction compliance reports.

– Compliance Prediction: Based on the trend of gas extraction in evaluation units, it estimates the compliance period and automatically adjusts the prediction time.

– Model Verification and Correction: Utilizing manually measured coal seam gas data, the system compares and verifies model analysis results. If deviations are detected, it can automatically correct the analysis model.

– Network Connectivity: Supports TCP/IP protocol, allowing direct connection to industrial Ethernet for remote centralized monitoring. It can also connect to the enterprise LAN for integrated management information system, enabling network information sharing.
