Abstract

A method for outputting failure handling method includes: detecting conditions of each part of a working machine; transmitting condition signals representing the detected conditions; receiving the condition signals; calculating a handling method for a failure showed by the received condition signals; and transmitting a handling signal representing the calculated handling method.

Claims

1. A method for outputting failure handling method, comprising:

detecting conditions of each part of a working machine by a condition detector provided in the working machine;

transmitting condition signals representing the detected conditions by a working machine side transmitter provided in the working machine;

receiving the condition signals by a working machine monitoring side receiver provided in a working machine monitoring facility;

calculating a handling method for a failure showed by the received condition signals, by a handling method calculating device provided in the working machine monitoring facility; and

transmitting a handling signal representing the calculated handling method by a working machine monitoring side transmitter provided in the working machine monitoring facility.

2. A method for outputting failure handling method according to claim 1, wherein said handling signal is also transmitted to any of the working machine, a service man and a manager of the working machine, by the working machine monitoring side transmitter provided in the working machine monitoring facility.

3. A method for outputting failure handling method according to claim 2, wherein when said handling signal is transmitted to the service man, a current location of the working machine is transmitted together by the working machine monitoring side transmitter provided in the working machine monitoring facility.

4. A method for outputting failure handling method according to claim 1, wherein said handling signal is transmitted together with information identifying the working machine and information indicating a nature of the failure, by the working machine monitoring side transmitter provided in the working machine monitoring facility.

5. A method for outputting failure handling method according to claim 1, wherein transmission and reception of the condition signals, and transmission of the handling signal, are carried out via a communications satellite.

6. A method for outputting failure handling method according to claim 1, wherein transmission and reception of the condition signals, and transmission of the handling signal, are carried out via a mobile communications system.

7. A method for outputting failure handling method according to claim 1, further comprising receiving the transmitted handling signal by a working machine side receiver provided in the working machine.

8. A failure handling method output system comprising:

a condition detector that is provided in a working machine and detects conditions of each part of the working machine;

a working machine side transmitter that is provided in the working machine and transmits condition signals representing the conditions detected by said condition detector;

a working machine monitoring side receiver that is provided in a working machine monitoring facility and receives the condition signals transmitted from said working machine side transmitter;

a handling method calculating device that is provided in the working machine monitoring facility and calculates a handling method for a failure shown by the condition signals received by said working machine monitoring side receiver;

a working machine monitoring side transmitter that is provided in the working machine monitoring facility and transmits a handling signal representing the calculated handling method; and

a working machine side receiver that is provided in the working machine and receives the transmitted handling signal.

9. A failure handling method output system according to claim 8, further comprising a monitor that displays the handling method based on the handling signal received by said working machine side receiver.

10. A failure handling output system according to claim 8, wherein said handling method calculating device calculates the handling method by searching a database using the condition signals received by said working machine monitoring side receiver.

11. A failure handling method output device comprising:

a receiver that receives condition signals representing conditions of each part of a working machine transmitted from the working machine;

a handling method calculating device that calculates a handling method for a failure shown by the received condition signals; and

a transmitter that transmits a handling signal representing the calculated handling method.

12. A failure handling method output device according to claim 11, wherein the transmitter transmits the handling signal representing the calculated handling method to the working machine.

13. A method for outputting failure handling method, comprising:

receiving condition signals representing conditions of each part of a working machine transmitted from the working machine;

calculating a handling method for a failure shown by the received condition signals; and

transmitting a handling signal representing the calculated handling method.

14. A method for outputting failure handling method according to claim 13, wherein reception of the condition signals and transmission of the handling signal are carried out via a communications satellite.

15. A method for outputting failure handling method according to claim 13, wherein reception of the condition signals and transmission of the handling signal are carried out via a mobile communications system.

16. A method for outputting failure handling method according to claim 13, wherein the handling signal representing the calculated handling method is transmitted to the working machine.

17. A failure handling method output device for receiving condition signals representing conditions of each part of a working machine transmitted from the working machine, calculating a handling method for a failure shown by the received condition signals, and transmitting a handling signal representing the calculated handling method.

18. A failure handling method output device according to claim 17, wherein the handling signal representing the calculated handling method is transmitted to the working machine.

19. A failure information acquisition method, comprising:

outputting information, relating to items to be checked when a failure occurs in a working machine, to a portable telephone terminal via a portable telephone system;

receiving information, which has been input at the portable telephone terminal regarding the items to be checked, via the portable telephone system; and

storing the received information in a storage device as failure information.
