Abstract

The invention discloses a marine distributed optical fiber time service system, comprising: a time-frequency host and several time-frequency extensions; module, a multi-reference source processing module, a time-frequency generation module, a display control module and an optical fiber module; the time-frequency extension includes a power supply module, a time-frequency control module, and a time-frequency generation module and an optical fiber module connected with the time-frequency control module; The time-frequency master and several time-frequency extensions are connected by two optical fiber cables through their respective optical fiber modules to form a time-frequency cascade loop. The invention provides a time-frequency homologous clock by forming a time-frequency cascading loop with a time-frequency main unit and a time-frequency sub-unit, thereby realizing a unified interface of the time-frequency equipment and unified monitoring and management.

Description

technical field [0001] The invention relates to the technical field of marine communication, in particular to a marine distributed optical fiber timing system. Background technique [0002] With the development of my country's national economy and national defense construction, more and more industries have put forward high requirements for the accuracy of time frequency. The so-called time system equipment is a kind of high-precision electronic equipment that can provide standard time-frequency signals for the system, which makes all the equipment in the system work under a unified time reference. Existing marine time-frequency equipment has various problems such as various types, poor interface compatibility, and lack of unified monitoring and management. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a distributed optical fiber time service system for ships in view of various problems such as various types o...
