Patent ID: 7099736

Claim:
An operational administration system furnished with one or more operational data storage/transmission devices connected to each of numerical controllers for one or more machine tools furnished with the numerical controllers, a terminal device provided where users use the machine tools, and an administration device provided where a manufacturer manufactures the machine tools, said administration device, said operational data storage/transmission devices, and said terminal device being provided to enable connection to one another via the Internet; wherein: said operational data storage/transmission devices comprise operational data storage means for storing data pertaining to operational status of the machine tools, and data gathering/transmission means for gathering from the numerical controllers data pertaining to the operational status of the machine tools, storing the data in said operational data storage means, and for checking whether a preset transmission condition is met, and only in instances in which the transmission condition is met, sending to said administration device in an e-mail data format the machine-tool operational status data stored in said operational data storage means; and said administration device comprises a database for storing machine-tool operational status data received from the operational data storage/transmission devices, data receiving/updating means for receiving machine-tool operational status data sent from said operational data storage/transmission devices, and respectively updating, with the operational status data received, the database-stored operational status data on each machine tool, ID data storage means for storing user ID information preestablished for each of the users in order to identify the users, correlatively with machine tool data for identifying the machine tools used by the users, and data transmission means, being a processor for transmitting to the terminal device operational status data stored in said database, for receiving user ID information entered through said terminal device, and for searching said ID data storage means based on the received user-ID information, checking whether the received user-ID information is stored in said ID data storage means, and only in instances in which the received user-ID information is stored, sending, in response to requests from said terminal device, to the requesting terminal device the operational status data for the machine tools identified by the machine tool data stored in said ID data storage means correlatively with the received user-ID information.
