Abstract

An object is to provide a remote maintenance system which can present a client with an avoiding action against the occurrence of an abnormality in the future. It is structured by a data measuring part 180 which measures operation data of a maintenance-receiving equipment of a client and outputs it, a residual lifetime predicting part 50 which receives the operation data outputted from the data measuring part 180 via the Internet 1, makes a diagnosis of the maintenance-receiving equipment, and predicts a residual lifetime of the maintenance-receiving equipment or its part, and a notifying part 40 which writes the result of the residual lifetime prediction by the residual lifetime predicting part 50 to an electric mail and notifies it to the client via the Internet 1.

Claims

1. A remote maintenance system comprising:

a data measuring part with a data measuring means which is installed in a maintenance-receiving equipment of a client for measuring operation data of the maintenance-receiving equipment and outputting it;

a storage part for receiving the operation data outputted from said data measuring part via a communication network and storing it;

a residual lifetime predicting part for making a diagnosis of the maintenance-receiving equipment based on past operation data stored in said storage part and the latest operation data received via the communication network and predicting a residual lifetime of the maintenance-receiving equipment or its part;

a notifying part for notifying the client of the result of the residual lifetime prediction by said residual lifetime predicting part via the communication network;

a displaying part for receiving the result of the residual lifetime prediction by said residual lifetime predicting part via the communication network, displaying the received result of the residual lifetime prediction, and displaying part information concerning the maintenance-receiving equipment, to be used for determining whether the part needs to be restocked or not; and

an ordering information outputting part for outputting ordering information of a repair part selected based on the result of the residual lifetime prediction and the part information displayed on said displaying part.

2. (Canceled)

3. A remote maintenance system comprising:

a data measuring part with a data measuring means which is installed in a maintenance-receiving equipment of a client for measuring operation data of the maintenance-receiving equipment and outputting it;

a storage part for receiving the operation data outputted from said data measuring part via a communication network and storing it;

a residual lifetime predicting part for making a diagnosis of the maintenance-receiving equipment based on past operation data stored in said storage part and the latest operation data received via the communication network and predicting a residual lifetime of the maintenance-receiving equipment or its part; and

a stock managing part for receiving a stock condition of repair parts in the client via the communication network, extracting the repair part having a fear of lack at lifetime limits of the parts in service calculated by the result of the residual lifetime prediction by said residual lifetime predicting part and instructing to supply the extracted repair part to the client.

4. (Canceled)
