<p><P>PROBLEM TO BE SOLVED: To improve the communication efficiency of an overall system, by unifying communication data flow in a plurality of communication systems, and by reducing the number of communication channels and the bus load. <P>SOLUTION: A central control unit CU for managing the plurality of communication systems TLi in an integrated manner is divided into a plurality of supervisors SVi. Each SVi is connected to a communication system TLi managed by the self-supervisor with bidirectional communications in transmission and reception, and connected to a communication system TLj managed by another supervisor SVj via a gateway so as to enable unidirectional communications. With this, each gateway is connected in chain in a unified manner, so that the entire inter-node communication can be covered, and the communication efficiency of the overall system can be improved by unifying the communication data flow of the plurality of communication systems, and by reducing the number of communication channels and a communication load. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
