Operation data accumulation and transmission device, operation management device, and operation management system

The operation data accumulation and transmission device according to clam 1, wherein said transmission condition is a condition set to an amount of data stored in said operation data storage means, and

• wherein said data collection and transmission means is configured so as to compare the amount of data stored in said operation data storage means to a reference amount of data as said transmission condition, and when aid amount of stored data reaches said reference amount of data, transmit the operating condition data stored in said operation data storage means to said operation management device.

An operation data accumulation and transmission device for connecting to a numerical control section of a machine tool provided with said numerical control section, collecting and accumulating data on an operating condition of said machine tool, and transmitting the accumulated data via telecommunication circuits to an operation management device, comprising:

• operation data storage means for accumulating the data on the operating condition of said machine tool;
• and
• data collection and transmission means for performing a process for connecting to said numerical control section, collecting the data on the operating condition of said machine tool, and storing the collected operating condition data in said operation data storage means, a process for generating the transmit data configured so as to associate a data-element identifier which defines the item concerning the operating condition with said operating condition data corresponding to this item based on the operating condition data stored in said operation data storage means, and a process for transmitting the generated transmit data via said telecommunication circuits to said operation management device.
