METHOD AND APPARATUS FOR TRANSMITTING MACHINE OPERATION DATA

摘要

To permit grasping operation conditions of a working machine at a control station located at a remote place no matter whether or not a trouble has occurred on the working machine, CPU 12 of a controller 3 arranged on a hydraulic excavator 1 produces operation data in accordance with signals outputted from operation detecting means 4 such as various sensors . These operation data are stored in a memory unit 13 on a basis of a time outputted from a clock unit 11, for example, depending upon the day. The operation data stored depending upon the day are outputted from an output unit 14 of the controller 3 to satellite communication terminal equipment 2, for example, when a key switch has been turned on. The operation data is transmitted from the satellite communication terminal equipment 2 to an earth station 6 via a communication satellite 5 and further, is automatically transmitted from the earth station 6 to a control station 8 via a telephone line 7 such that said operation data can be obtained as daily report data or the like by operating PC at the control center 8.
