Communication system and communication device |
摘要 |
Provided are a communication system and a communication device capable of suppressing attenuation of a communication signal superimposed upon a control pilot line. This output circuit (20) sends a control pilot signal which has been generated at a voltage generation source (21) to an input circuit (60). Between the control pilot line (4) and the ground line (3) of the output side of the output circuit (20), a communication unit (30) is connected via a transformer (31). Between the control pilot line (4) and the ground line (3) of the input side of the input circuit (60), a communication unit (70) is connected via a transformer (71). Between the output circuit (20) and the transformer (31), a lowpass filter (33) is interposed. Between the input circuit (60) and the transformer (71), a lowpass filter (73) is interposed. |

1. A communication system provided with an output circuit that is provided in an electricity supply apparatus supplying electricity to a vehicle and that outputs a rectangular wave signal of given frequency and with an input circuit that is provided in the vehicle and connected to the output circuit through a plurality of signal lines and that receives the rectangular wave signal outputted by the output circuit, whereby a communication signal is superimposed on the signal lines so that communication is achieved between the vehicle and the electricity supply apparatus, the communication system comprising:
a first communication unit provided in the electricity supply apparatus and transmitting and receiving a communication signal via a first transformer connected between the signal lines; a second communication unit provided in the vehicle and transmitting and receiving a communication signal via a second transformer connected between the signal lines; a first lowpass filter interposed between the output circuit and the first transformer; and a second lowpass filter interposed between the input circuit and the second transformer, wherein
the output circuit outputs a rectangular wave signal of 1 kHz; anda rise time and a fall time of the rectangular wave signal on an input side of the input circuit are 10 μs or shorter. |
