Abstract

The invention discloses an ocean node time service system and time service method, and the system comprises a GPS signal distribution amplifier which is used for receiving a wireless GPS signal whichcomprises time information and amplifying and outputting the wireless GPS signal, a GPS time service controller connected with the GPS signal distribution amplifier and used for receiving the wirelessGPS signals transmitted by the GPS signal distribution amplifier, extracting time information contained in the wireless GPS signal, generating a time information signal, and synchronously generatinga second pulse signal according to the time information, and converting the time information signal and the second pulse signal into a target time information signal and a target second pulse signal of a specified level and ocean node equipment connected with the GPS time service controller and used for determining the current time according to the received target time information signal and the target pulse per second signal. According to the invention, accurate time service of ocean node equipment can be realized.

Description

technical field [0001] The invention relates to the technical field of marine seismic exploration and acquisition, in particular to a marine node timing system and a timing method. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In recent years, Ocean Bottom Node (OBN) equipment is becoming the mainstream acquisition equipment for offshore exploration, and its business development prospects are huge, with an average annual growth rate of about 20%. The ocean node device is a seismic data acquisition unit that can independently sample and store multiple components (3-component geodetic + 1-component piezoelectric) independently; there is no cable connection between ocean node devices, and there is no data transmission problem between nodes ;The marine node seismic system has ...
