Patent ID: 8855009

Claim:
A method for providing communication data that provides communication data, which is utilized to identify a device on a mobile object at the time of communication, to the device on a mobile object that is installed on a mobile object and constitutes at least a part of a network system that performs communication in accordance with a predetermined communication protocol through an LAN, the method comprising: generating the communication data that should be set to the device on a mobile object based on prepared data generation information representing the communication data predetermined in association with a mobile object identification code previously provided to the mobile object on which the device on a mobile object is installed to enable identifying the mobile object and the mobile object identification code of the mobile object on which the device on a mobile object to which the communication data should be set is installed; providing the generated communication data to the device on a mobile object as the communication data that should be set to the device on a mobile object; sequentially storing failure history information and diagnosis results with time about the device on a mobile object, and generating a routing table in dependence upon a generated static I.P. address for the LAN, in a first information storage unit; sequentially recording a condition of a brake as time-series data from start to end of an operation, and receiving a user ID and a password in a second information storage unit in dependence upon a vehicle number input, wherein the first information storage unit, the second information storage unit, and the device on a mobile object are connected with each other; and communicating between the device on a mobile object and a ground device, wherein the ground device is installed on the ground and is connected to the device on a mobile object through the LAN, wherein the ground device includes a collection server unit that collects and stores mobile object information, an authentication server unit that authenticates access to an access point, and at least one wireless communication unit that communicates with the device on a mobile object.
