System for monitoring component of operating machine
First Claim
1. A system for monitoring a component which can be exchangeably mounted to a working machine, comprising:
- a control device which is provided to said working machine; and
a management device which is connected to said control device via a communication network so as to be capable of mutual communication therewith, wherein;
a wireless tag, in which first component identification information for identifying this component is stored, is provided in advance to said component;
said working machine comprises a position measurement device for measuring a current position of the working machine;
said control device comprises;
a checking timing detection means for detecting whether or not a checking timing, which has been set in advance, has arrived; and
a component identification information acquisition means which, if said checking timing has arrived, acquires said first component identification information from said wireless tag via an information reading means, associates said acquired first component identification information with identification information of said working machine, and transmits said acquired first component identification information, said identification information of said working machine and the current position of said working machine measured by the position measurement device to said management device via said communication network; and
said management device comprises;
a component information management means for managing second component identification information related to genuine components;
a component monitoring means which decides whether said first component identification information which has been received from said control device and said second component identification information which is managed by said component information management means agree with one another or not, and which, if said first component identification information and said second component identification information agree with one another, decides whether said identification information of said working machine associated with said first component identification information is associated with said second component identification information and, if said first component identification information and said second component identification information do not agree with one another, outputs a decision result to the effect of non-agreement; and
an updating means which, if it has been decided by said component monitoring means that said first component identification information and said second component identification information agree with one another and it is decided that said second component identification information and said identification information of said working machine have not been associated, updates the contents stored in said component information management means so that said second component identification information, for which this agreement has been decided, is associated with said identification information of said working machine.

Abstract
A working machine is provided with a plurality of exchangeable components, and each component is provided with a wireless tag. A component ID is stored in advance in the wireless tag. When, on the side of the working machine, a component exchange timing or an engine starting timing is detected, the component ID stored in the wireless tag is acquired, and is transmitted to a working machine management device. The working machine management device checks the component ID which has been received from the working machine and a component ID which is stored in a component ID storage means against one another. And, if these two component IDs do not match one another, an abnormal state detection means outputs a warning signal.

11. A management device for a working machine which is connected via a communication network to a control device provided to said working machine so as to be capable of mutual communication therewith, wherein:
-
a wireless tag, in which is stored first component identification information for identifying a component which can be exchangeably mounted to said working machine, is provided in advance to this component; and said first component identification information is acquired by said control device;
said management device comprising;a component information management means for managing second component identification information related to genuine components; a component monitoring means which receives said first component identification information which has been acquired by said control device, has been associated with said identification information of said working machine, and has been transmitted together with a current position of said working machine measured by position measurement device mounted in said working machine, decides whether said second component identification information which is managed by said component information management means and said first component identification information agree with one another or not, and, if said first component identification information and said second component identification information agree with one another, decides whether or not said identification information of said working machine information associated with said first component identification information is associated with said second component identification information and, if said first component identification information and said second component identification information do not agree with one another, outputs a decision result to the effect of non-agreement; and an updating means which, if it has been decided by said component monitoring means that said first component identification information and said second component identification information agree with one another and it is decided that said second component identification information and said identification information of said working machine have not been associated, updates the contents stored in said component information management means so that said second component identification information, for which this agreement has been decided, is associated with said identification information of said working machine.
