Abstract

The invention relates to an optimizing time synchronizing device for multi-channel clock sources. The optimizing time synchronizing device comprises at least two units identical in structure. In every unit, a global positioning system ground receiver (8) is connected with a counter (7), the counter (7) is further connected with a comparator (6) in the unit, a high-stability crystal oscillator (1) is directly connected with the counter (7) in every unit or connected with the counter (7) in every unit through a phase-locking frequency multiplier (2), and the comparator (6) in every unit is respectively connected with one input end of a multiplexer (4). The counter (7), the comparator (6) and a register (5) in every unit are respectively connected with a single chip microcomputer (3), and the output end of the single chip microcomputer (3) is further connected with the multiplexer (4). The optimizing time synchronizing device has the advantages that the comprehensive cost is low, algorithm adaptability is high, optimization of the multi-channel clock sources is supported, various time difference compensation strategies are supported, high-precision punctuality can be achieved, and time signal output is stable and reliable, and the like.
