<p>A method and device for detecting inductive components in communication line is provided and applied to communication field. The said method comprises the steps of: inputting detecting signal to the said communication line; sampling the time field voltage vector of detecting signal input of the said communication line; generating differential input impedance amplitude-frequency characteristic curve of detecting signal input of the said communication line based on the time field voltage vector obtained by sampling; and determining the number of inductive components in the said communication line based on the number of apexes or zeros on the said curve. The present invention implements the auto detection of the number of inductive components in communication line, e.g. load coils, telephone separators, and so on, the determination is accurate, the efficiency is increased, and the cost of fault judge of communication line is decreased.</p> |
