通信装置、充電通信システム、輸送機器及び故障診断方法

Japanese Patent JP6586396

B2

A communication device comprises a connector to which a communication line is to be connected for sending and receiving a control signal concerning charge control between a transportation apparatus and a charging apparatus, a modem outputting a modulated signal obtained by modulating information to be sent and demodulating the modulated signal input, and a first internal communication line and a second internal communication line each being connected to the connector and the modem, the first internal communication line and the second internal communication line respectively being for sending the modulated signal and being for receiving the modulated signal, and sends and receives the modulated signal by superposing the modulated signal on the control signal. The modem outputs a beacon signal for communication, and comprises a branch line branched at an intermediate location of the second internal communication line, a wave detector circuit that detects the beacon signal transmitted to the branch line by way of the first internal communication line, the connector and the second internal communication line, and a diagnosis unit that performs a fault diagnosis of its own device based on a signal obtained through detection by the wave detector circuit.
