Problems solved by technology

[0002] Optical fiber sensing is widely used, but in general, one optical fiber transmits one signal, and the utilization rate of optical fiber sensing is not high; when the amount of transmitted information increases, if the transmission signal is increased by increasing the laying amount of optical fibers, the communication cost will be greatly increased

Abstract

The invention discloses a distributed communication method, system and device based on optical fiber sensing and a storage medium. The method comprises the following steps: controlling laser equipment to emit pulse laser to an optical fiber according to a preset rate; a plurality of terminal devices are distributed on the optical fiber at intervals; acquiring a series of reflected signals of the pulse laser according to a preset sampling frequency and storing according to a preset format; wherein the series of reflected signals of the pulse laser are generated by a plurality of terminal devices vibrating the optical fiber according to a preset packaging format by adopting a first vibration frequency or a second vibration frequency; converting the series of reflected signals of the pulse laser from the time domain to the frequency domain, and determining a signal transmission value according to the vibration intensity of the first vibration frequency and the vibration intensity of the second vibration frequency in the frequency domain signal; and verifying the signal transmission value according to a preset packaging format to determine a transmission signal. The embodiment of the invention can greatly improve the communication transmission capacity of the optical fiber, and can be widely applied to the technical field of optical communication.

Description

technical field [0001] The present invention relates to the technical field of optical communication, and in particular, to a distributed communication method, system, device and storage medium based on optical fiber sensing. Background technique [0002] Optical fiber sensing is widely used, but in general, one optical fiber transmits one signal, and the utilization rate of optical fiber sensing is not high; when the amount of transmitted information increases, if the transmission signal is increased by increasing the laying of optical fibers, the communication cost will be greatly increased. If the communication transmission capacity of a single optical fiber can be improved, it can not only save costs, but also promote the further development of optical fiber sensing. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the embodiments of the present invention is to provide a distributed communication method, system, device and storage medium based on optic...
