Problems solved by technology

[0004] The present invention solves the problem of high cost of monitoring equipment in the existing power optical fiber monitoring mode, various monitoring equipment, few monitoring lines, inflexible monitoring mode, low degree of automation, waste of manual labor, which may lead to long-term interruption of optical fiber communication and online optical power. The detection method of automatic switching of monitoring faults is prone to interruption of optical fiber communication due to misreporting and miscutting. The polling monitoring method of spare fiber cores not only wastes optical fiber resources, but also increases the cost of monitoring equipment due to the OTDR module, and cannot achieve a set of equipment to obtain optical fibers. Network status and other problems, and at the same time, there are problems affecting the quality of normal communication due to the large insertion loss of monitoring equipment. Provide an online monitoring and automatic detection system for urban power fiber optic networks

Abstract

The invention discloses an urban power optical fiber network online monitoring and automatic detection system and relates to the field of power system optical fiber communication. The problems that inan existing power optical fiber monitoring mode, monitoring equipment cost is high and monitoring equipment is complex are solved. The system comprises optical fiber network center communication station monitoring equipment and L groups of substation communication station monitoring devices. Online monitoring is carried out on power optical fiber lines of an urban power optical fiber network. According to the system, on the basis of improving element sharing degree in the equipment and reducing monitoring cost, working fiber cores and standby fiber cores of communication stations are monitored at the same time, whole network online monitoring of a communication optical fiber network of an urban power system is realized; structure expansion is carried out according to optical fiber networkexpansion; after the expansion is carried out, the whole network online monitoring of the communication optical fiber network of the urban power system is realized; fault line automatic detection isrealized under multi-optical fiber line fault condition; when optical fiber resources in the optical fiber lines are in shortage, field configuration does not need to be carried out at the substationcommunication stations; and a monitoring mode is remotely switched.
