s101, driving a plurality of light sources in the optical fiber sensing host to send first combined light waves to an optical cable in the power pipeline.
In this embodiment, the optical fiber sensing host may be disposed in a central control room of a substation, and is used to monitor a plurality of power pipes in a power pipe gallery, and acquire various physical characteristics related to the power pipes in the monitoring process.
The optical fiber sensing host comprises a communication ODF optical distribution frame which can be used for connecting optical cables in a plurality of power pipelines. The optical fiber sensing host comprises a control system, and the central control room can send control instructions to the control system so that the optical fiber sensing host can execute corresponding operations.
In one example, as shown in fig. 2, an optical fiber sensing host is connected to a sensing optical fiber in an electric power pipeline, and the optical fiber sensing host includes a control system, a distributed optical fiber temperature measurement light source, a distributed external force destruction light source, a distributed discharge monitoring light source, a wavelength division multiplexer, and a circulator, wherein, in order to distinguish functions of two wavelength division multiplexers in the optical fiber sensing host, the wavelength division multiplexer for performing wavelength combination is referred to as a first wavelength division multiplexer, and the wavelength division multiplexer for performing wavelength division is referred to as a second wavelength division multiplexer.
