When the first node (10) is in a sleep state, the first node (10) is activated when an activation factor that is not caused by communication with other nodes is generated in the first node (10). When activated, the first node (10) transmits an activation request signal to the second node (20) via the first communication line (4). The first node (10) further transmits an activation request signal to the second node (20) via the first communication line (4) when a transmission condition between the first node (10) and the second node (20) is satisfied. The second node (20) is activated when the second node (20) receives an activation request signal from the first communication line (4) when the second node (20) is in a sleep state.
第一节点(10)在该第一节点(10)为睡眠状态时,在该第一节点(10)中产生了不由与其它的节点的通信引起的启动因素的情况下启动。第一节点(10)若启动,则经由第一通信线(4)向第二节点(20)发送启动要求信号。第一节点(10)还在与第二节点(20)之间发送条件成立的情况下,经由第一通信线(4)向第二节点(20)发送启动要求信号。第二节点(20)若在该第二节点(20)为睡眠状态时从第一通信线(4)接收启动要求信号则启动。
