Abstract: In view of the current backward law enforcement level of coal mine safety supervision departments, irregular law enforcement supervision behavior and other industrial issues, the coal mine law enforcement system based on strapdown inertial navigation is designed by studying mems technology, inertial navigation technology, Bluetooth positioning technology, CS architecture technology and real time distributed database technology, the system includes three parts: the law enforcement terminal, the safety production law enforcement platform and the law enforcement supervision cloud platform, which realizes the standardization of law enforcement personnel law enforcement, the synchronization of underground law enforcement data, the accurate and autonomous navigation of law enforcement process, and the tracing of law enforcement track, it provides the credible law enforcement information for the cloud platform of coal mine law enforcement supervision.
