Working machine, data communcation system for working machine, operation system for working machine, and setting change system for working machine

A data communication system for a working machine, comprising:

• a mobile terminal including a storage part;
• a control device provided in the working machine, and configured to make data communication with the mobile terminal, the control device including a working machine-use ID code and a registration code stored therein, the working machine-use ID code being different from the registration code, wherein the machine-use ID code is pre-assigned to said working machine when manufactured, and the registration code is pre-set for said working machine and used for a user registration;
• an ID code registration device configured to perform said user registration by checking whether a registration code inputted by a user matches with said registration code stored in the control device, and configured to, only when the registration code inputted by the user matches with said registration code stored in the control device, transmit the working machine-use ID code stored in the control device to the mobile terminal and to instruct the mobile terminal to register said transmitted working machine-use ID code as a mobile-use ID code, said mobile-use ID code being saved in the storage part of the mobile terminal and used for an authentication process;
• an ID code checking device configured to, during said authentication process, check whether said mobile-use ID code stored in the mobile terminal and said working machine-use ID code stored in the control device match with each other;
• and
• a data communication device configured to enable data communication between the mobile terminal and the control device when the ID code checking device establishes matching between the mobile-use ID code and the working machine-use ID code and to disable the data communication when the ID code checking device does not establish the matching.

An operation system for a working machine, comprising:

• a management configured to manage the working machine;
• a mobile terminal configured to make wireless communication with said working machine and with said management server;
• a working unit configured to perform working, the working unit being provided to the working machine;
• and
• a control device provided to said working machine, the control device including a working machine-use ID code and a registration code stored therein, the working machine-use ID code being different from the registration code, wherein the machine-use ID code is pre-assigned to said working machine when manufactured, and the registration code is pre-set for said working machine and used for a user registration, and wherein the control device is configured to perform said user registration by checking whether a registration code inputted by a user matches with said registration code stored in the control device, wherein:
• said management server comprises:
• an ID code transmitting device configured to, only when the registration code inputted by the user matches with said registration code stored in the control device, transmit the working machine-use ID code stored in the control device to the mobile terminal and to instruct the mobile terminal to register said transmitted working machine-use ID code as a mobile-use ID code, the mobile-use ID code being issued based on the user registration and saved in the mobile terminal for use for an authentication process,
• said mobile terminal comprises:
• a data storage device configured to receive the transmitted working machine-use ID code transmitted from said ID code transmitting device and to store the received mobile-use ID code, and
• a data transmitting device configured to transmit said mobile-use ID code stored in said data storage device to said working machine for the authentication process, and
• said control device comprises:
• an ID code checking device configured to, during said authentication process, check whether the mobile-use ID code transmitted from said mobile terminal and said working machine-use ID code stored in the control device match with each other;
• and
• a control restriction device configured to allow normal control of the control device when the ID code checking device establishes matching between the mobile-use ID code and the working machine-use ID code and not to allow the normal control when the ID code checking device does not establish the matching.
