COMMUNICATION DEVICE AND COMMUNICATION SYSTEM USING SAME

摘要

The present invention addresses the problem of reducing the possibility of erroneously acquiring data included in a communication signal. A communication device (10) is provided with a reception unit (11) and a control unit (13). The reception unit (11) receives a communication signal (S1) transmitted by a change in voltage (Vt1) applied between a pair of electric wires (41A, 41B), and outputs a reception signal corresponding to the communication signal (S1). The control unit (13) monitors whether or not the reception signal rises during a first determination period and monitors whether or not the reception signal falls during a second determination period to thereby determine bits of data included in the communication signal (S1) and perform processing for acquiring the data. The control unit (13) is configured to set the respective timings of the first determination period and the second determination period on the basis of the pulse width of a bit corresponding to a start bit in the reception signal.
