Abstract

A hydraulic excavator 1 working in fields includes a controller 2 for measuring a working time for each of an engine 32, a front 15, a swing body 13, and a travel body 12, storing measured data in a memory of the controller 2, and then transferring it to a base station computer 3 via satellite communication, an FD, etc. The transferred data is stored as a database 100 in the base station computer 3. The base station computer 3 reads the data stored in the database 100 for each hydraulic excavator, calculates a working time of a part belonging to each section on the basis of the working time of that section, and compares the calculated working time with a preset target replacement time interval of the relevant part, thereby calculating a remaining time up to next replacement of the relevant part and managing the scheduled replacement timing thereof. Thus, the appropriate scheduled replacement timing of parts can be determined even in a construction machine having a plurality of sections that differ in working time from each other.

Claims

1. A method for managing a construction machine, the method comprising:

a first step of measuring a working time for each of sections in each of a plurality of construction machines, transferring the measured working time for each section to a base station computer, and storing and accumulating the transferred working time as operation data in a database;

a second step of, in base station computer, reading the operation data regarding a particular construction machine from said database and calculating a scheduled repair/replacement timing of a part belonging to each section on the basis of the working time of said section.

a third step of executing processing to allow a maker and a user of said particular construction machine to learn said scheduled repair/replacement timing calculated in said second step, respectively.

2. A method for managing a construction machine according to claim 1, wherein said second step includes steps of calculating, based on said read operation data, a working time of a part belonging to each section on the basis of the working time of said section, and comparing the calculated working time with a preset target repair/replacement time interval, thereby calculating a remaining time up to next repair/replacement of the relevant part.

3. A method for managing a construction machine according to claim 1, wherein said construction machine is a hydraulic excavator, and said sections include a front, a swing body, a travel body, an engine, and a hydraulic pump of the hydraulic excavator.

4. A system for managing a construction machine, the system comprising:

operation data measuring and collecting means for measuring and collecting a working time for each of sections in each of a plurality of construction machines; and

a base station computer installed in a base station and having a database for storing and accumulating, as operation data, the working time measured and collected for each section,

said base station computer including first means for reading the operation data of a particular construction machine from said database and calculating a scheduled repair/replacement timing of a part belonging to each section on the basis of the working time of said section and second means for executing processing to allow a maker and a user of said particular construction to learn said scheduled repair/replacement timing calculated by said first means respectively.

5. A system for managing a construction machine according to claim 4, wherein said first means calculates, based on said read operation data, a working time of a part belonging to each section on the basis of the working time of said section, and compares the calculated working time with a preset target repair/replacement time interval, thereby calculating a remaining time up to next repair/replacement of the relevant part.

6. A system for managing a construction machine according to claim 4, wherein said construction machine is a hydraulic excavator, and said sections include a front, a swing body, a travel body, an engine, and a hydraulic pump of the hydraulic excavator.

7. A processing apparatus comprising:

a database for storing and accumulating, as operation data, a working time for each of sections in each of a plurality of construction machines, first means for reading the operation data regarding a particular construction machine from said database, and calculating a scheduled repair/replacement timing of a part belonging to each section on the basis of the working time of said section, and second means for executing processing to allow a maker and a user of said particular construction to learn said scheduled repair/replacement timing calculated by said first means respectively.

8. A processing apparatus comprising:

a database for storing and accumulating, as operation data, a working time for each of sections in each of a plurality of construction machines, first means for reading the operation data regarding a particular construction machine from said database, calculating a working time of a part belonging to each section on the basis of the working time of said section, and comparing the calculated working time with a preset target repair/replacement time interval, thereby calculating a remaining time up to next repair/replacement of the relevant part, and second means for executing processing to allow a maker and user of said particular construction to learn said scheduled repair/replacement timing calculated by said first means respectively.
