Universal type time synchronization system and implementation method

Abstract

The invention relates to a universal time synchronization system and an implementation method. The universal time synchronization system includes a receiving part, a clock part and an output part; a GPS / BD receiver unit, a 2Mbit receiving unit and an optical fiber IRIG-B(DC) receiving unit of the receiving part, a network unit, a display unit and a power supply unit of the clock part, as well as a PPS (TTL) output unit, a PPS (idle contact) output unit, an NTP output unit, a PTP output unit, an optical fiber IRIG-B (DC) output unit, an RS232 output unit, an RS422 output unit and an alarm output unit of the output part are respectively connected with a main control unit of the clock part; and the main control part performs processing such as data rationality judgment, punctuality and data protocol conversion on GPS / BD, B code and 2M signals which are received by the receiving part in an ARM, an FPGA and a punctuality module. According to the universal time synchronization system and implementation method of the invention adopted, high-precision and fully-functional time service equipment can receive four kinds of time service source signals, namely, Beidou, GPS, optical fiber B code and 2M signals, and therefore, an original mode that time service and positioning can be realized only relying on wireless satellite signals can be realized, and a defect of excessive reliance on a wireless positioning system can be avoided.

Description

technical field [0001] The invention relates to a time synchronization system, in particular to a general-purpose time synchronization system and an implementation method. Background technique [0002] The existing time synchronization system has limitations in the type of receiving signal source and the form of the output interface. The punctual accuracy and working stability in various working modes are not reliable, the punctual accuracy is poor, the signal resolution ability and the output interface are common. Problems such as weak compatibility cannot meet the needs of various fields. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a general-purpose time synchronization system and an implementation method. The specific technical solution is that a general-purpose time synchronization system includes three parts, namely a receiving part, a clock part, and an output part. It is characterized in ...
