The intelligent gas inspection system for coal mines addresses issues such as low efficiency in traditional equipment management, numerous target points, and poor reliability. Aiming to "reduce manpower, improve efficiency, and increase safety," it achieves full-process intelligent upgrades through four core technologies. Fixed points use high-precision laser six-parameter sensors and LED smart screens to enhance the accuracy and real-time performance of discrete point monitoring. The handheld devices integrate a laser dual-parameter portable instrument, e-ink screen, and Bluetooth/NFC technology to enable "one-click synchronization" of manual inspection data, solving the problems of missed or incorrect inspections. The system supports inspection planning, automatic alarms, report statistics, and fault diagnosis.
