Patent ID: 8854183

Claim:
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.
