<p><P>PROBLEM TO BE SOLVED: To provide a communication system which is capable of significantly enhancing a degree of flexibility, accuracy, efficiency and so on of product manufacturing in a product manufacturing plant with P2P communication for data and control signals regarding product manufacturing in a plant with high security and reliability. <P>SOLUTION: This is a communication system for product manufacturing in a plant. The plant is hierarchized into a three hierarchies, that is, a work unit hierarchy, a process unit hierarchy comprising individual process unit where one process or combination of a plurality of processes which are conducted by one or a plurality of work units are considered as one work unit, and a manufacturing unit hierarchy to manufacture products by including all of the process unit hierarchy. A P2P (peer-to-peer) method wireless communication is built at least at a part of transmission and reception of data, control signal and so on between an arbitrary unit hierarchy and another unit hierarchy, an inner part of the unit hierarchy and an inner part of machinery and so on. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
