Working machine, failure diagnosis system for work machine and maintenance system for machines
First Claim
1. A working machine maintenance system comprising:
- a plurality of working machines; and
a center server that manages maintenance on the plurality of working machines by engaging in data exchange through bidirectional communication with each of the plurality of working machines via a communication line, wherein;
the working machines each include an operation data storage device that stores operation data and maintenance data, an operation device operated to enter a maintenance work completion, a data transmission device that transmits the operation data, maintenance work completion data provided through the operation device and the maintenance data to the center server, a data reception device that receives data related to maintenance information transmitted from the center server and a display device at which the maintenance information is displayed; and
the center server includes a data reception device that receives the operation data, the maintenance work completion data and the maintenance data that have been transmitted, an operation database in which the operation data are stored, a maintenance database in which the maintenance data are stored, a calculation device that calculates maintenance timing based upon the operation data stored in the operation database and the maintenance data stored in the maintenance database and a data transmission device that transmits data related to the maintenance information including the maintenance timing to a working machine.

Abstract
A working machine failure diagnosis method for performing a failure diagnosis by transmitting and receiving signals through communication devices provided at a working machine and at an information management center, according to the present invention, includes: a first step in which a first signal related to a failure of the working machine is generated at the working machine and the first signal is transmitted to the information management center from the working machine via the communication devices; a second step in which, after the first signal is transmitted, the information management center generates a second signal for identifying a location of the failure based upon the first signal and the second signal is then transmitted from the information management center to the working machine via the communication devices; and a third step in which failure information corresponding to the first signal and the second signal is provided to an operator.
