The invention discloses a real-time data transmission system for a mine automation system. the real-time data transmission system can dynamically read real-time data in the mine automation system OPCServe service, and performs the data statistics, data analysis, and data display. the real-time data transmission system comprises an OPC Server data reader, a data receiver, a data statistical analyzer, a data distributor, and a thread management unit; a client program is unnecessary to deploy, and the operation and maintenance are simple. The real-time data transmission system disclosed by the invention has the features of being stable and reliable in operation, fast in response speed, and rich in monitoring analysis information. The operation time of the master draining pump, a ventilator,an air compressor, and a main belt conveyor can be counted, the main well hoist hook amount can be counted, the belt operation state (full-load and empty-load), the equipment fault and like conditionscan be analyzed and nudges, thereby providing evidence for scientifically scheduling command and production and reasonably arranging equipment use and maintenance.
