Leaky coaxial cable detection method and device of multi-system access platform and leaky coaxial cable detection system

Abstract

The invention discloses a leaky coaxial cable detection method and device of a multi-system access platform and a leaky coaxial cable detection system. The detection method comprises that in responseto a detection operation starting instruction, a detection signal is sent to a leaky coaxial cable; the initial signal power detected by main detection equipment of the detection signal is obtained; present auxiliary detection equipment is selected from pieces of auxiliary detection equipment successively according to a preset detection sequence; the practical signal power detected by the presentauxiliary detection equipment of the detection signal is obtained for each selected present auxiliary detection equipment; a power difference between the practical signal power and the initial signalpower is calculated; whether the power difference satisfies the preset insertion loss requirement is determined; and if NO, it is determined that a leaky coaxial cable circuit between the present auxiliary detection equipment and the main detection equipment has a problem. The leaky coaxial cable installation condition of the multi-system access platform is monitored remotely in real time, and theleaky coaxial cable fault is located.

Description

technical field [0001] The invention belongs to the field of leaky cable loss detection, and in particular relates to a leaky cable detection method and device for a multi-system access platform and a leaky cable detection system. Background technique [0002] Leaky cable is the abbreviation of leaky coaxial cable (Leaky Coaxial Cable), usually referred to as leaky cable or leaky cable. Its structure is basically the same as that of ordinary coaxial cable. The conductor consists of three parts. While the electromagnetic wave is transmitted longitudinally in the leaky cable, the electromagnetic wave is radiated to the outside through the slot; the external electromagnetic field can also be induced into the inside of the leaky cable through the slot and transmitted to the receiving end. When testing whether the leaky cable of the multi-system platform (POI, Pointof Interface) is installed correctly and whether there is an open circuit in the existing technology, one of the me...

Problems solved by technology

However, the existing testing technology has the following defects: when it is necessary to test whether there is a problem with the insertion loss of the leaky cable when the POI leaky cable device is used, the heavy equipment must be manually carried, and the input and output ports of the POI leaky cable device need to be disconnected for testing. device, causing a communication interruption
