Abstract

Error information and alarm information transmitted from a construction machine (2) is fetched by a server (8). A replacement possibility determining section (815) in the server (8) determines a utilization area of the construction machine (2) from positional information stored in a positional information database (825), and reads out a load to the parts in the utilization area (lifetime of parts in the utilization area) from a utilization environment load database (827). When the parts having transmitted the error information or alarm information has reached the lifetime limit in the utilization area and accumulated utilization time of the construction machine is not less than a prespecified utilization time, or when times of transmission of the error information is not less than prespecified times or duration of transmission of the alarm information is not less than a prespecified period of time, the replacement possibility determining section (815) determines that the parts having transmitted the error information or alarm information is an object for replacement.

Claims

1. A supplemental parts production forecasting system for forecasting production, when an abnormality occurs in parts constituting a machine, of supplemental parts to be replaced with the parts comprising:

an error/alarm information fetching section for fetching error information or alarm information transmitted from the machine and indicating parts with abnormality and contents of the abnormality in the machine;

a utilization record fetching section for fetching utilization record of the machine transmitted from the machine;

a utilization record accumulating section for sequentially accumulating the fetched utilization records;

a replacement possibility determining section for determining whether the parts with the abnormality generated therein is an object for replacement with supplemental parts or not based on the error information or alarm information fetched by the error/alarm fetching section as well as on the utilization record accumulated in the utilization record accumulating section; and

a production forecasting section for forecasting production of the supplemental parts to be replaced with the parts when it is determined that replacement of the parts is necessary by the replacement possibility determining section.

2. The supplemental parts production forecasting system according to claim 1, wherein the utilization record includes times of transmission of the error information or duration of transmission of the alarm information from the machine.

3. The supplemental parts production forecasting system according to claim 1, wherein the utilization record includes accumulated utilization time of the machine.

4. The supplemental parts production forecasting system according to claim 1 further comprising:

a positional information fetching section for fetching information concerning a position of utilization of the machine transmitted from the machine.

5. The supplemental parts production forecasting system according to claim 1 further comprising:

a designed lifetime storing section for storing therein designed lifetimes for parts of the machine; and

a utilization environment load storing section with utilization environment load to parts of the machine stored therein in correspondence to utilization environments for the machine,

wherein the replacement possibility determining section searches the designed lifetime of parts stored in the designed lifetime storing section and load to the parts in a specific utilization environment stored in the utilization environment load storing section and determines the possibility of replacement based on the error information or the alarm information, the utilization record, designed lifetime, and utilization environment load.

6. The supplemental parts production forecasting system according to claim 1 further comprising:

a stock number storing section with a stock number of the supplemental parts stored therein; and

a stock number updating section for sequentially updating the stock number stored in the stock number storing section,

wherein the production forecasting section comprises a stock checking section for checking the number of stocked supplemental parts stored in the stock number storing section when it is determined by the replacement possibility determining section that replacement of the parts is necessary; and

a production instructing section for instructing production of the parts when it is determined by the stock checking section that the recognized number of stocked parts is not more than prespecified parts.

7. A supplemental parts production forecasting method of forecasting production of supplemental parts to be replaced with the parts when any abnormality occurs in parts constituting the machine, the method comprising:

an error/alarm information fetching step of fetching error information or alarm information transmitted from the machine and indicating parts of the machine with the abnormality occurring therein and contents of the abnormality;

a utilization record fetching step of fetching a utilization record for the machine transmitted from the machine;

a utilization record accumulating step of sequentially accumulating the fetched utilization records;

a replacement possibility determining step of determining, based on the error information or alarm information fetched in the error/alarm information fetching step and utilization records accumulated in the utilization record accumulating step, whether the parts with the abnormality occurring is an object for replacement with supplemental parts or not; and

a supplemental parts production forecasting step of forecasting production of the supplemental parts to be replaced with the parts when it is determined in the replacement possibility determining step that replacement is required.

8. A program for making a computer execute a supplemental parts production forecasting method of forecasting production of supplemental parts to be replaced with the parts when any abnormality occurs in parts constituting the machine, the method comprising

an error/alarm information fetching step of fetching error information or alarm information transmitted from the machine and indicating parts of the machine with the abnormality occurring therein and contents of the abnormality;

a utilization record fetching step of fetching a utilization record for the machine transmitted from the machine;

a utilization record accumulating step of sequentially accumulating the fetched utilization records;

a replacement possibility determining step of determining, based on the error information or alarm information fetched in the error/alarm information fetching step and utilization records accumulated in the utilization record accumulating step, whether the parts with the abnormality occurring is an object for replacement with supplemental parts or not; and

a supplemental parts production forecasting step of forecasting production of the supplemental parts to be replaced with the parts when it is determined in the replacement possibility determining step that replacement is required.

9. A recording medium storing a program recorded in a manner readable by a computer

wherein the program makes a computer execute a supplemental parts production forecasting method of forecasting production of supplemental parts to be replaced with the parts when any abnormality occurs in parts constituting the machine, the method comprising

an error/alarm information fetching step of fetching error information or alarm information transmitted from the machine and indicating parts of the machine with the abnormality occurring therein and contents of the abnormality;

a utilization record fetching step of fetching a utilization record for the machine transmitted from the machine;

a utilization record accumulating step of sequentially accumulating the fetched utilization records;

a replacement possibility determining step of determining, based on the error information or alarm information fetched in the error/alarm information fetching step and utilization records accumulated in the utilization record accumulating step, whether the parts with the abnormality occurring is an object for replacement with supplemental parts or not; and

a supplemental parts production forecasting step of forecasting production of the supplemental parts to be replaced with the parts when it is determined in the replacement possibility determining step that replacement is required.
