Long gas transmission pipeline distributing type monitoring inertia time service system

The utility model discloses a long gas transmission pipeline distributing type monitoring inertia time service system adds GPS time service system (comprising GPS antenna, GPS receiver, central processing unit ) and high accuracy clock system (comprising central processing unit and high accuracy temperature compensation type crystal oscillator ) simultaneously in the system. Compensate the time service task of GPS time service system under the abnormal behavior with high accuracy clock system. When the normal during operation of GPS system, carry out the time service with the GPS system, if the GPS system is influenced by weather, geomagnetic field and leads to the fact the in disorder or unable time service of time service, do the inertia time service with the high accuracy clock, guaranteed the long gas transmission pipeline distributing type interconnected system task in the time of accomplishing incessant high accuracy under any external disturbance circumstances of monitoring.
