MANAGEMENT SYSTEM FOR MOBILE WORK MACHINE

摘要

PURPOSE:To provide a management system for mobile work machine which performs efficient maintenance and management and reduces the cost. CONSTITUTION:When a portable radio communication machine 25 which the operator of the work machine carries is connected to connectors 26a and 26b, a communication controller 23 detects this connection and transmits data extracted from an operation controller 21 to a repeating station 4 through a data converter 24 and the portable radio communication machine 25. This repeating station 4 transmits pertinent data to a transmitter-receiver 13 on the side of a data management part 1 through a telephone line, and transmitted data is recorded in a data recording part 14. Analysis related to maintenance of the work machine is performed based on this data. Thus, the work machine is efficiently maintained in a relatively inexpensive constitution without hands.
