This invention discloses an intelligent interlocking and audible-visual early warning system for cantilever tunneling machines based on sensor fusion. This invention relates to the field of safety technology for mining tunneling equipment, solving the technical problem that existing mining tunneling equipment often uses manual three-way ball valves for hydraulic interlocking to switch oil circuits.
