GPS time synchronizer used in relay system of submarine optical cables

Abstract

The invention discloses a GPS time synchronizer used in a relay system of submarine optical cables, and mainly relates to a satellite synchronous clock device. The GPS time synchronizer comprises a GPS time synchronizer body and a case, wherein a solenoid valve is arranged on a shell of the case; a gas generator, a pressure sensor, a thermostat, a singlechip and a damper are arranged in the case; the bottom of the pressure sensor is fixed on the bottom surface of the inside of the case; a pressure sensing end of the pressure sensor is connected to the top surface of the inside of the case; and the singlechip is used for controlling the pressure sensor, the gas sensor and the solenoid valve. The internal pressure intensity of the case is adjusted by external pressure intensity of the case, the temperature in the case can be constant, and when the earthquake of a seabed occurs, the damper can protect the GPS time synchronizer against being collided violently.

Description

technical field [0001] The invention relates to a satellite synchronous clock device, in particular to a GPS time synchronization machine used in a submarine optical cable relay system. Background technique [0002] The GPS satellite synchronous clock device is used to receive radio signals transmitted by GPS space satellites, thereby obtaining and providing standard time information to users. It is an electronic instrument that establishes a time scale and realizes unified time synchronization. When the GPS satellite synchronous clock device needs to be used outdoors, take the device out of the room temperature environment and place it in a cold environment in cold weather. The inside of the device's casing is prone to frost. When the device is turned on, the internal heat will melt the frost on the casing. Melting into water will cause damage to the inside of the device. A submarine fiber optic cable is a wire wrapped in insulating material that is laid on the seabed to e...

Problems solved by technology

The interior of the relay station is hollow and filled with air. In the relay station, a GPS time synchronization machine is required to regulate the time-related parameters of each system. However, the current GPS time synchronization machine has no anti-pressure function, so pressure fluctuations often appear in the deep sea relay station. It will cause more or less damage to the GPS time synchronization machine, and the temperature in the deep sea is low, which will also have a certain impact on the functioning of the GPS time synchronization machine
