The present invention discloses an optical cable fault detection system. The optical cable fault detection system comprises a plurality of fault detection stations, a fault communication terminal, a fault detection center and a plurality of personal communication terminals. The fault detection stations include fault indicators and wireless communication nodes, the fault indicators are connected with temperature sensing assemblies and strain sensing assemblies and are connected with the fault communication terminal through the wireless communication nodes; and the fault detection center includes a data receiving unit, a data analysis unit, a data backup unit and a console, and the console is communicated with the personal communication terminals. The detection system provided by the invention is applicable to tabular optical cables, and the fault indicators matching the tabular optical cables are especially designed in the detection stations and are configured to accordingly regulate positions of the temperature sensing assemblies and the strain sensing assemblies, so that the deficiencies of the small contact sensing area, difficulty in fixation, easy displacement and easy mutual interference of temperature measurement and strain measurement of the conventional circular structure sensing cable and the fault indicator are overcome.
Description
technical field [0001] The invention relates to the technical field of optical cable testing, in particular to an optical cable fault detection system. Background technique [0002] In engineering, relatively fragile optical fibers need to be protected. Optical fibers are used in the form of optical cables. The basic type of optical cables is optical fibers plus protective structures. According to the degree of correlation between optical fibers and protective structures, they are mainly divided into two types: tight structure and loose structure. kind. Distributed optical fiber measurement and sensing systems can be roughly divided into two categories: strain and temperature. Although both of them hope that the external strain and temperature will be transmitted to the optical fiber as soon as possible, but the strain of the optical fiber will interfere with temperature detection. Therefore, when detecting strain, it is desirable that the optical fiber in the cable has a t...
