Abstract

The invention provides a method and a device for measuring the length of a conductor cable. The method for measuring the length of a conductor cable comprises the steps that an initiating frame signalis transmitted to a conductor cable to be measured, the initiating frame signal comprises a first timing point, and a first moment when the first timing point is transmitted is recorded; a response frame signal transmitted by a response device is received through the conductor cable, the response frame signal comprises a second timing point, and a second moment when the second timing point is received is recorded; a time feedback frame signal transmitted by the response device is received, wherein the time feedback frame signal comprises a third moment when the response device receives the first timing point and a fourth moment when the response device transmits the second timing point; and the length of the conductor cable is measured according to the first moment, the second moment, thethird moment and the fourth moment. According to the invention, online measurement and measurement of the total length of multiple lines are supported, and harm to equipment connected to the lines isreduced.

Description

technical field [0001] The present application relates to communication technology, in particular to a method and device for measuring the length of a conductor cable. Background technique [0002] Conductor cables are wire products used to transmit electric energy and information, as well as realize electromagnetic energy conversion, usually including one or more conductor cores. Cables are important assets and infrastructure for power grid companies, telecom operators, network or cable TV service providers, and other enterprises that use cables in large quantities for production or service. Because the status of the cable is so basic and important, it is necessary to know its information in detail, especially the length of the cable working on the network, which is very important for such enterprises to check the cable consumption, inventory assets, and guide capacity expansion. significance. When the cable leaves the factory, the length information is marked on the oute...
