Abstract: In view of problems of difficult management for field devices and hard to fulfill application of existing device management system in coal mine, the paper proposed a design scheme of dynamic management information system for coal mine devices. The system is based on uniform encoding management of devices in mine wide, takes responsible zone and team as unit, management device as object, personnel behavior as essential factor, rules, regulations and measures as standard, patrol routine as drive, and combines personnel location system, bar code, two-dimension code and patrol devices at related points, so as to realize life-cycle management for coal mine devices.
