<p>PURPOSE:To efficiently execute the grasp of the operating status of respective mobile apparatuses mounting card readers, information exchange, inspection instructions, data collection, and management such as IN/OUT management by attaining radio communication between an LAN station and the respective, mobile apparatuses. CONSTITUTION:One of plural LAN stations 6 transmits data through radio equipments 11, 12. The equipment 11 can communicate with mobile tracks 15 for instance. When cards 17 provided with apparatus IDs are inserted into card readers 16 mounted on the tracks 15, the equipments 11, 12 transmit the status of the tracks 15 to the station 6 and a data processor 1 manages the tracks 15. The equipment 12 can execute radio communication also with a radio IC card 13 and a handy terminal 14. Consequently the management of the mobile apparatuses in a construction working field and the communication of an information apparatus, e.g. carried by a person can be attained in addition to the management of a temporary apparatus, etc., and various management, inspection instructions to the field, data collection from the field, etc., can be efficiently executed.</p> |
