    • In a communication system, nodes are coupled to a transmission path in a bus topology. The nodes communicate with each other via the transmission path using communication signals that have a communication frequency and are synchronized with a power supply signal. Each of the nodes includes a coupling portion that transmits and receives the communication signal and the power supply signal using electromagnetic induction in non-contact with the transmission path. Each of the nodes determines whether a collision of the communication signals occurs on the transmission path based on a voltage level of a signal that has the communication frequency and is induced at the coupling portion.
    • 在通信系统中,节点被耦合到总线拓扑中的传输路径。 节点通过使用具有通信频率并与电源信号同步的通信信号经由传输路径彼此通信。 每个节点包括使用与传输路径非接触的电磁感应来发送和接收通信信号和电源信号的耦合部分。 每个节点基于具有通信频率并在耦合部分被感应的信号的电压电平来确定传输路径上是否发生通信信号的冲突。

    • In a master apparatus, a reference device generates a reference signal, a power feeding signal generation portion divides or multiples a frequency of the reference signal to generate a power feeding signal, a first communication carrier generation portion divides or multiples the frequency of the reference signal to generate a first communication carrier, a communication signal generation portion generates a communication signal, and a superimposition portion superimposes the communication signal on the power feeding signal. In a slave apparatus, a separation portion separates the superimposition signal into a power feeding signal and a communication signal, a second communication carrier generation portion divides or multiples a frequency of the power feeding signal separated by the separation portion to generate a second communication carrier, and a modulation and demodulation portion modulates and demodulates a data communication signal to be communicated with the master apparatus using the second communication carrier.
