Clock signal processing method and equipment

Abstract

The invention discloses a clock signal processing method and equipment, which are applied to a process for processing a clock signal by using an indoor clock unit in a clock zoom-out time service system. Indoor clock unit equipment is used for receiving a clock signal transmitted by an outdoor clock unit through a transmission link, performing photoelectric conversion on the received clock signal, recovering a clock signal from the converted clock signal and outputting the recovered clock signal.

Description

technical field [0001] The invention relates to a clock signal processing technology, in particular to a clock signal processing method applied to the remote clock technology of a time service system and an indoor clock unit device in the remote clock system. Background technique [0002] At present, the traditional timing system mainly relies on the direct timing of satellite navigation systems, including GPS (Global Positioning System, Global Positioning System) and Beidou generation. Its timing system such as figure 1 As shown, it mainly includes: satellite 11, antenna 12, radio frequency line 13, satellite navigation receiver 14 and other parts. The satellite signal received by the antenna 12 is transmitted to the satellite navigation receiver 14 through the radio frequency line 13, and the satellite navigation receiver 14 recovers PPS (PulsesPerSecond, pulse per second) and TOD (TimeofDate, date and time) for use by the next-level equipment. [0003] In the above solu...
