Problems solved by technology

[0004] Regardless of the above-mentioned prior art, the abnormality data is automatically transmitted to the remote management authority only when an abnormality occurs in an operating machine such as a construction machine. It is effective, but for the working status of the operating machinery that has not yet experienced an abnormality, the remote management office cannot grasp

Abstract

A control office located in a remote place is adapted to keep informed of the operating condition of a machine irrespective of whether the machine is in trouble. A CPU (12) of a control device (3) on a hydraulic shovel (1) creates operation data according to a signal from detector means (4) such as sensors. Storage (13) stores daily operation data at the time determined by a timer (11). An output device (14) of the control device (3) provides the stored daily operation data for a satellite communication terminal device (2), for example, when a key switch is turned on. The satellite communication terminal device (2) transmits the data to a ground base station (6) through a communications satellite (5). The ground base station (6) automatically transmits the data through a telephone circuit (7) to a control office (8), in which the data can be used as daily report data on a personal computer.

Description

technical field [0001] The present invention relates to a work data transmission method and device for a work machine that automatically transmits work data of a hydraulic excavator type work machine to a remote management office. Background technique [0002] As such prior art, there is, for example, a maintenance system for a working machine disclosed in JP-A-7-166582. This prior art includes, when the operator of the working machine communicates with the remote management department (the management department) regarding the abnormal phenomenon of the working machine, following the instructions issued by the management department through the remote operation, the The data stored in the controller of the work machine is automatically transmitted to the authority through communication means such as radio station, telephone line or the like. [0003] As another prior art, there is, for example, a machine abnormality monitoring device and method disclosed in JP-A-11-65645. I...
