<P>PROBLEM TO BE SOLVED: To provide a communication apparatus which collects information transmitted wirelessly from a plurality of subordinate communication nodes and collects desired information efficiently from all node devices even in the case where the number of node devices becomes large or becomes varied, without fundamentally changing a configuration of hardware. <P>SOLUTION: A communication apparatus comprises: communication path termination means which is formed individually on different channels C1-Cn, and terminates simplex communication paths P1-Pn where a plurality of communication nodes p1-pn are arranged respectively; and control means which triggers transmission for the communication paths P1-Pn in series with an interval not less than a difference in a descending sequence of a required transmission time t1-tn (t1>...>tn) for each round-trip of the communication paths P1-Pn. <P>COPYRIGHT: (C)2012,JPO&INPIT |
