  • Communication power line status detecting method and system using the method
    Patent number: 9035751
    Abstract: A communication power line status detecting method and a system using the method provided by the present disclosure is suitable for used in a transmission device and a receiving device which are connected by a communication power line. The transmission device transmits a communication indicator signal through the communication power line. When the receiving device receives the communication indicator signal from the communication power line, it converts the communication indicator signal into a time domain in order to analyze the signal reflection and transmission status of the communication indicator signal when it is transmitted via the communication power line, and to generate a line status information corresponding to the communication power line.
