Estimating the term…
A working time for each of an engine 32, a front 15, a swing body 13, and a travel body 12 of a hydraulic excavator 1 working in fields is measured. Measured data is stored in a memory of a controller 2 and then transferred to a base station computer 3 via satellite communication, an FD, etc. to be stored in a database 100. At each repair/replacement of a part in each hydraulic excavator, the base station computer 3 calculates, based on the operation data, a replacement time interval of the part on the basis of the working time per section to which the part belongs, and then stores and accumulates it. The base station computer also reads the stored data for each hydraulic excavator, determines, for each part, a replacement rate of the part having the substantially equal replacement time interval, and calculates a target replacement time interval of the part in accordance with the replacement time interval corresponding to a maximum replacement rate. Thus, the appropriate target replacement time interval can be decided and the appropriate scheduled replacement timing can be determined even for parts belong to a plurality of sections that differ in working time from each other.
A method for managing a construction machine, comprising the steps of statistically processing an actual repair/replacement time interval for each of parts of a plurality of construction machines (1, 1a, 1b, 1c), comparing the statistically processed data with operation information of a particular construction machine, and deciding a scheduled repair/replacement timing of a corresponding part of the particular construction machine.
A method for managing a construction machine, the method comprising:
A system for managing a construction machine, the system comprising means (2, 40-46, 3, 50, 51, S306, 308) for statistically processing an actual repair/replacement time interval for each of parts of a plurality of construction machines (1, 1a, 1b, 1c), and means (3, 50, S36) for comparing the statistically processed data with operation information of a particular construction machine, and deciding a scheduled repair/replacement timing of a corresponding part of the particular construction machine.
A system for managing a construction machine, the system comprising:
A processing apparatus (3) which statistically processes an actual repair/replacement time interval for each of parts of a plurality of construction machines (1, 1a, 1b, 1c), compares the statistically processed data with operation information of a particular construction machine, and decides a scheduled repair/replacement timing of a corresponding part of the particular construction machine.
A processing apparatus (3) which stores and accumulates, as operation data, a working time for each of sections (12, 13, 15, 21a, 21b, 32) in each of a plurality of construction machines (1, 1a, 1b, 1c), determines, based on repair/replacement data for each part of the construction machine and said operation data, an actual repair/replacement time interval of each part on the basis of the working time per section to which the relevant part belongs, statistically processes the actual repair/replacement time interval, and sets a target repair/replacement time interval of the relevant part using the statistically processed data.
