DATA COMMUNICATION SYSTEM FOR WORKING MACHINE

摘要

A management server includes a user management database in which mobile terminal identification information on the mobile terminal and working machine identification information on a sold working machine are registered in association with each other, a user registration determination unit adapted to determine whether or not the mobile terminal and the working machine are registered in association with each other on the basis of the mobile terminal identification information and the working machine identification information outputted from the mobile terminal and the mobile terminal identification information and the working machine identification information stored in the user management database, and an authorization information output unit adapted to output an authorization key necessary for wireless communication between the mobile terminal and the working machine in the case where the user registration determination unit determines that the mobile terminal and the working machine are registered in association with each other.

1. A data communication system for a working machine, comprising:
a data communication device configured to obtain data relating to the working machine; a mobile terminal configured to receive the data of the data communication device by wireless communication; and a management server configured to output an authorization key for wireless communication between the data communication device and the mobile terminal, wherein the mobile terminal includes: an information output unit configured to output, to the management server, a mobile terminal identification information and a working machine identification information, the mobile terminal identification information identifying the mobile terminal, the working machine identification information identifying the working machine; and an authorization key output unit configured to output, to the data communication device, the authorization key outputted from the management server, the management server includes: a user management database configured to register the mobile terminal identification information relating to the mobile terminal and the working machine identification information relating to a sold working machine and to relate the mobile terminal identification information and the working machine identification information to each other; a user registration determination unit configured to determine whether or not the mobile terminal and the working machine are registered to be related to each other on the basis of the mobile terminal identification information and the working machine identification information each outputted from the mobile terminal and of the mobile terminal identification information and the working machine identification information each stored in the user management database; and an authorization information output unit configured to output the authorization key necessary for wireless communication between the mobile terminal and the working machine when the user registration determination unit determines that the mobile terminal and the working machine are registered to be related to each other, and the data communication device includes a communication authorization unit configured to authenticate the authorization key outputted from the mobile terminal with an authorization key previously stored in the communication authorization unit to determine validation of the authorization key outputted from the mobile terminal, and to authorize wireless communication between the data communication device and the mobile terminal when determining validation of the authorization key outputted from the mobile terminal.
