Abstract

The application provides a method and a device for measuring the length of a conductor cable. The method for measuring the length of the conductor cable of the present application includes: transmitting an initiation frame signal to the conductor cable to be measured, the initiation frame signal including a first timing point, recording the first moment of transmitting the first timing point; receiving through the conductor cable The response frame signal transmitted by the response device, the response frame signal includes the second timing point, and the second moment of receiving the second timing point is recorded; the time feedback frame signal transmitted by the response device is received, and the time feedback frame signal includes the response device receiving the first timing point The third moment and the fourth moment when the response device transmits the second timing point; the length of the conductor cable is obtained by measuring the first moment, the second moment, the third moment and the fourth moment. The application supports on-network measurement and total length measurement of multi-segment lines, and reduces the harm to equipment connected on the line.

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...
