Design of image tracking system for track transportation of coal mine inclined drifts

For problem that track transportation of coal mine inclined drifts has long transport distance, steep slope and many turnoffs, so winch driver cannot know conditions along the track timely, which leads to a big security risk, the paper put forward a design scheme of image tracking system for track transportation of coal mine inclined drifts based on automatic matrix switching. The system obtains tramcar position in the tunnel through shaft encoder, and uses PLC control matrix to achieve automatic image switching and displaying when the tramcar is detected at coverage area of a certain video camera. Field application results show that the system has high reliability and strong practicability.
