DYNAMIC STATE MANAGEMENT SYSTEM FOR MINING EQUIPMENT

摘要

The purpose of this invention is to monitor the state of equipment such as repeaters and vehicle-mounted wireless communication devices used in mining, and/or to accurately monitor states of travel paths. To this end, an information gathering device (10) transmits, via a second wireless communication device (18) and at a prescribed timing, a position information request command which requests transmission of position information of dump trucks (20), and, on the basis of the response to this position information request command, and determines at least one of: the state of the dump trucks (20), the state of repeaters (3) which relay communications from a first wireless communication device of the dump trucks (20) to the second wireless communication device (18), and the state of travel routes of the dump trucks (20).
