Abstract
(EN)
A communication system according to one embodiment of the present invention comprises: a control circuit including a transmission end and a reception end that are connected to each other through a bus bar, wherein the transmission end transmits a first signal to the reception end by using a first voltage applied to the bus bar, and the reception end receives the first signal and transmits a second signal to the transmission end by using a reference current flowing into the bus bar; and a charging circuit which receives the first voltage through the bus bar so as to perform charging, and which supplies a driving voltage to the control circuit, wherein the control circuit comprises a filter unit for generating a second voltage by extracting a voltage having a reference range from a peak voltage of the first voltage, and a voltage measurement unit for extracting the first signal by measuring the second voltage.
