Abstract

The invention provides an electric power communication laser scanning device. A main optical fiber is connected with a light source emitter and is divided into a plurality of optical fiber sections; for each optical fiber section, the second end, far away from the light source emitter, of the optical fiber section is connected with the first end of the circulator; the second end of the circulatoris respectively connected with the first end of the middle-section optical fiber and the input end of the optical splitter through a second change-over switch; the input end of the next optical fibersection is respectively connected with the second end of the middle section optical fiber and the first output end of the optical splitter through a third change-over switch; the second output end ofthe optical splitter is connected with the input end of the fiber Bragg grating; the reflection output end of each fiber Bragg grating is connected with the third end of the circulator, the fourth endof the circulator is connected with the auxiliary optical fiber, the photoelectric detector is connected with the auxiliary optical fiber, the wavelengths of optical signals capable of being reflected back by the fiber Bragg gratings are different, and the pulse intensities of the optical signals with different wavelengths in the light source signals provided by the light source emitter are different. The fault detection efficiency of the optical fiber section can be improved.

Description

technical field [0001] The invention belongs to the field of power communication network maintenance, and in particular relates to a power communication laser scanning device. Background technique [0002] At present, when detecting whether there is a fault in the power communication network, it is usually necessary for inspectors to go to the corresponding road section where the optical fiber is laid to detect the section of optical fiber. Obviously, the detection efficiency is low. Contents of the invention [0003] The invention provides a laser scanning device for electric power communication to solve the problem of low detection efficiency of faulty sections of optical fibers at present. [0004] According to the first aspect of the embodiments of the present invention, there is provided a power communication laser scanning device, which includes a main optical fiber, a backup optical fiber and an auxiliary optical fiber. Device A is respectively connected to the mai...
