Abstract

Operating information (a pilot pressure, a pump pressure, a hydraulic oil temperature, an engine rotational speed, an hour meter and the like) of a hydraulic excavator and use environment information (operator information) of the hydraulic excavator are transmitted to a center server together with body information (for example, a model, a type, a type number, an identification number and the like) from the hydraulic excavator. For example, when a hydraulic hose as a replaceable component of the hydraulic excavator is replaced, the replaceable component information (a replaceable component name and a replacement date) is transmitted to the center server from a computer for maintenance. The center server predicts a replacement time of the replaceable component (hydraulic hose) using the use environment information of the hydraulic excavator in addition to the operating information and the replaceable component information of the hydraulic excavator.

Claims

1. A replaceable component management system for a construction machine comprising:

an operating information memory section for storing operating information including a detection value and an operating time of each of components in a construction machine;

a replaceable component information memory section for storing replaceable component information including a use start date of a replaceable component in said construction machine requiring replacement upon coming to the end of their life; and

a replacement time predicting section for predicting a replacement time of said replaceable component by using said operating information stored in said operating information memory section and said replaceable component information stored in said replaceable component information memory section, characterized in that;

said replaceable component management system for the construction machine includes;

a use environment memory section for storing, as use environment information of said construction machine, at least one use aspect of use aspects of said construction machine including an operator, a user, a business category of a user, an area of a user, a working content, and a working area of said construction machine, which is information different from said operating information and said replaceable component information, wherein

said replacement time predicting section predicts the replacement time of said replaceable component by using said use environment information stored in said use environment memory section in addition to said operating information and said replaceable component information, wherein

said construction machine is provided with a readout device that reads out said identification information of a portable device in which specific identification information is recorded, and

at least one of said use aspects corresponding to said identification information of said portable device read out by said readout device is stored as said use environment information in said use environment memory section.

2. The replaceable component management system for the construction machine according to claim 1, wherein

said construction machine includes an activation determining section that determines whether or not an activation of said construction machine is permitted based upon said identification information of said portable device read out by using said readout device.

3. The replaceable component management system for the construction machine according to claim 1, wherein

said replacement time predicting section predicts the replacement time of said replaceable component based upon a present degree of progress of a life of said replaceable component calculated using said operating information and said replaceable component information and a future degree of the progress of the life of said replaceable component calculated using said operating information and said use environment information.

4. The replaceable component management system for the construction machine according to claim 3, wherein

said replacement time predicting section calculates said present degree of the progress of the life of said replaceable component by using said use environment information in addition to said operating information and said replaceable component information.
