Mode switchable smart optical cable monitoring system and method

Abstract

The invention discloses a mode switchable smart optical cable monitoring system and method. The system comprises a light source module, a network management server, an RTU unit device and a client computer. According to the system and the method, the problem that an existing optical cable monitoring device cannot realize the fact that three working modes: a standby fiber test, an online test and protection monitoring are taken into consideration by the same RTU device at the same time is solved. The mode switchable smart optical cable monitoring system is provided. When the system is applied,24-hour all-whether real-time automatic monitoring can be carried out on an optical cable state; the system has a relatively high detection probability, a relatively low false alarm probability and the relatively high optical cable breakpoint positioning precision; the system has a rapid optical cable protection switching function; the normal operation of an original transmission system is not influenced; and the system has various alarm modes: a short message, a mail and sound and light. When the system is applied, the three working modes: the standby fiber test, the online test and the protection monitoring can be taken into consideration by the same RTU device at the same time. No matter which working mode is employed, an optical fiber in an optical cable is occupied, so optical fiber resources are greatly saved.

Description

technical field [0001] The invention relates to optical cable monitoring, in particular to an intelligent optical cable monitoring system and method with switchable modes. Background technique [0002] According to the "2015 Statistical Bulletin of the Communication Operation Industry" issued by the Ministry of Industry and Information Technology in early 2016, in 2015, 4.413 million kilometers of new optical cable lines were built nationwide, and the total length of optical cable lines reached 24.873 million kilometers. From 2010 to 2015, the growth rate of the total length of optical cable lines exceeded 20. %. Correspondingly, the maintenance tasks of the optical cable network will be more onerous. At present, the traditional optical cable maintenance method still mainly relies on manual labor, and basically follows the following process: fault occurs - notify the maintenance unit - drive to the fault site - test with OTDR - find the approximate location of the manhole -...
