<p><P>PROBLEM TO BE SOLVED: To provide sensor nodes and a data collection system using them by which the concentration of communication traffic on a control terminal can be avoided and a burden on the control terminal can be reduced. <P>SOLUTION: The sensor nodes 5 and 6 are connected with a communication network, and detect random information. The sensor nodes 5 and 6 include a reception means 51, a destination readout means 54, and a transmission means 56. The reception means 51 is connected with the communication network, and receives an order table which stores the order of nodes in a group of nodes including other sensor nodes for detecting random information and its own node in association with communication addresses of the nodes. The destination readout means 54 refers to the order table received by the reception means 51, and reads out the communication address of the sensor node after its own node. The transmission means 56 transmits the order table received by the reception means 51 and detection data obtained by its own node to the communication address of its own node. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
