Abstract

The position of a working machine is detected, a position signal representing the detected position is transmitted, the position signal is received, management information relating to the working machine is calculated based on the received position signal, and the calculated management information is transmitted to the working machine. Example of management information is type of attachment depending on soil quality, and weather forecasts.

Claims

1. A work management method for work sites, comprising the steps of:

detecting a position of a working machine;

transmitting a position signal for the detected position;

receiving the position signal;

calculating soil quality at the site of the working machine based on the received position signal;

calculating attachment information for the working machine based on the calculated soil quality; and

transmitting the calculated attachment information to a working machine side receiver.

13. A work management method for work sites according to claim 1, wherein:

the attachment information for the working machine is information such as a type of bucket claw, a type of bucket shape, or a type of excavating bit.

2. A work management method for work sites, comprising the steps of:

detecting a position of a working machine;

transmitting a position signal for the detected position;

receiving the position signal;

calculating telephone number of related facilities in the vicinity of the work site of the working machine based on the received position signal; and

transmitting the calculated telephone number.

3. A work management method for work sites, comprising the steps of:

detecting a position of a working machine;

transmitting a position of a working machine;

transmitting a position signal for the detected position;

receiving the position signal;

calculating weather forecasts at the site of the working machine based on the received position signal; and

updating a work schedule chart for the working machine that has been created in advance, based on the calculated weather forecast information.

4. A work management system for work sites, comprising:

a position detector that detects the position of a working machine;

a working machine side transmitter that transmits a position signal for the position detected by the position detector;

a working machine monitoring side receiver that receives the position signal of the working machine transmitted from the working machine side transmitter;

a soil quality calculator that calculates soil quality at the site of the working machine based on the position signal received by the working machine monitoring side receiver;

an attachment information calculator that calculates attachment information for the working machine based on the soil quality calculated by the soil quality calculator;

a working machine monitoring side transmitter that transmits the attachment information calculated by the attachment information calculator to a working machine side receiver; and

the working machine side receiver that receives the attachment information transmitted from the working machine monitoring side transmitter.

14. A work management system for work sites according to claim 4, wherein:

the attachment information for the working machine is information such as a type of bucket claw, a type of bucket shape, or a type of excavating bit.

5. A work management system for work sites, comprising:

a position detector that detects the position of a working machine;

a working machine side transmitter that transmits a position signal for the position detected by the position detector;

a working machine monitoring side receiver that receives the position signal of the working machine transmitted from the working machine side transmitter;

a calculator that calculates telephone number of related facsimiles in the vicinity of the site of the working machine based on the position signal received by the working machine monitoring side receiver;

a working machine monitoring side transmitter that transmits the calculated telephone number to a working machine side receiver; and

the working machine side receiver that receives the telephone number transmitted from the working machine monitoring side transmitter.

6. A work management system for work sites, comprising:

a position detector that detects the position of a working machine;

a working machine side transmitter that transmits a position signal for the position detected by the position detector;

a working machine monitoring side receiver that receives the position signal of the working machine transmitted from the working machine side transmitter;

a calculator that calculates weather forecast information for the site of the working machine based on the position signal received by the working machine monitoring side receiver;

an updater that updates a work schedule chart for the working machine created in advance, based on the calculated weather forecast information; and

a working machine side receiver that receives the updated work schedule chart transmitted from the working machine monitoring side transmitter.

7. A management information device for work sites, comprising:

a soil quality calculator that calculates soil quality at the site of the working machine based on a transmitted position of a working machine;

an attachment information calculator that calculates attachment information for the working machine based on the soil quality calculated by the soil quality calculator; and

a transmitter that transmits the attachment information calculated by the attachment information calculator to the working machine side receiver.

15. A management information device for work sites according to claim 7, wherein:

the attachment information for the working machine is information such as a type of bucket claw, a type of bucket shape, or a type of excavating bit.

8. A management information system for work sites, having a management information device comprising:

a soil quality calculator that calculates soil quality at the site of the working machine based on a transmitted position of a working machine;
