Abstract: A scheme is proposed about the locatable automatic gas inspection system based on Android. By open source characteristics of Android, the gas acquisition circuit and the positioning card from the original mine personnel positioning system are integrated at the hardware level. The gas concentration and location information are obtained automatically in the form of multi-serial communication, and stored in the SQLite database, then the data are uploaded to the ground integrated dispatching system through underground wireless network. The locatable automatic gas inspection system can effectively solve some problems in coal mine gas inspection work, such as the gas inspection is not comprehensive, the inspection record upload is not timely, the cost of additional positioning equipment construction is high, etc.
