Description

Technical Field

[0001] The invention relates to the technical field of optical cable monitoring, and in particular to an optical cable online monitoring device based on a geographic information system. Background Art

[0002] As an important guarantee for the development of the national economy, the safe and efficient operation of the power grid is of great strategic significance. Reliable and effective monitoring of the power grid status is an effective way to ensure its safe and reliable operation. It is also an important guarantee for building a controllable, safe, reliable, environmentally friendly and economical smart grid.

[0003] In the existing technology, in the research of optical cable fault monitoring technology, most of the optical cable monitoring at home and abroad currently adopts network technology, database technology, and geographic information technology to realize centralized monitoring and resource management of optical fiber networks. In terms of system architecture, a three-level structure is generally adopted to divide the optical cable monitoring system into three levels: monitoring station, regional monitoring center, and general monitoring center. In the optical cable monitoring management, the monitoring of optical cables is realized by combining a dedicated multi-channel optical power meter, OTDR equipment, and optical switches. When the optical cable is wired, an optical cable junction box will be set at the wiring end for protection.

[0004] However, general optical cable junction boxes are hung on communication poles or cable trenches and are greatly affected by the climate and environment. After years of exposure to the sun and rain, the sealed seals are prone to aging. Once water enters and accumulates, the optical fiber coating will be corroded by acidic sewage and easily break. What is more serious is that in winter, the water in the shell freezes, causing stress changes in the optical fiber, increasing the loss and significantly reducing the transmission quality. When the ice melts, the loss often returns to normal. Especially in the southern region, it often occurs alternately day and night, which brings us confusion in fault diagnosis.

When the optical cable detection device detects it, it is more troublesome to continuously inspect the optical cable. This avoids the general optical cable junction box being greatly affected by the climate environment due to being hung in the communication pole or cable trench. After years of exposure to the sun or rain, the sealed seals are prone to aging. Once water seeps in, the optical fiber coating will be corroded by acidic sewage and easily break. What's more serious is that in winter, water accumulates in the shell and freezes, causing stress changes in the optical fiber, increasing losses and significantly reducing transmission quality. When the ice melts, the loss often returns to normal. Especially in the southern region, it often alternates between day and night, which confuses us in fault diagnosis.
