Intelligent collective fault diagnosis and online temperature measurement system

Abstract

The invention relates to an intelligent collection type fault diagnosis and on-line temperature measuring system. A common power supply place is arranged in a testing area, composite low-voltage optical fiber cables are accessed to different user sides from the common power supply place, an intelligent collection monitoring platform is arranged in the common power supply place and respectively connected with a first upper computer and a second upper computer, the first upper computer is connected with a fault diagnosis host machine, the second upper computer is connected with an on-line temperature measuring host machine, the fault diagnosis host machine is connected with optical fibers in the composite low-voltage optical fiber cables, and the on-line temperature measuring host machine is connected with temperature measuring optical fibers which are laid on surfaces of the composite low-voltage optical fiber cables. According to the intelligent platform, devices with two different functions are collected in the same monitoring platform, cable temperature on-line monitoring and optical fiber fault real-time judgment in the composite low-voltage optical fiber cables in the testing area can be finished in the same platform, and the system has the advantages of intelligent advancement and economic practicality.

Description

technical field [0001] The invention relates to a power transmission network, in particular to an intelligent platform for monitoring on a power transmission and information network. The intelligent platform has functions of fault diagnosis and online temperature measurement at the same time. Background technique [0002] In recent years, with the rapid growth of my country's economy, the rapid development of the power grid, and the advancement of grid intelligence, high-speed information transmission channels based on optical fiber communication have been formed, but this has also led to the continuous expansion of the power communication network. It is becoming more and more complex, and the basic resources of electric power communication cannot be effectively utilized, which seriously restricts the development of intelligent power distribution and utilization. [0003] Fiber-to-the-home is an inherent requirement for the development of smart grids, and the State Grid Corpo...

Problems solved by technology

[0004] In the actual PFTTH (power fiber to the home) network cable fault handling, the traditional OTDR (optical time domain reflectometer) can not meet the access network multi-branch, one-way high loss real-time Quickly and accurately find the geographical location of the fault point and delay the handling of the accident, resulting in increased losses

At the same time, OPLC cables have the characteristics of wide distribution network, large geographical range, strong sporadic failure, difficult daily inspection, large disaster loss and high recovery cost.
