【摘要】：為實現(xiàn)時間同步裝置高穩(wěn)定輸出,針對多時源選擇、守時算法、動態(tài)調(diào)整這3個關(guān)鍵環(huán)節(jié)提出了方法及實現(xiàn)步驟。在多時源選擇方面,提出基于聚類算法的外部獨立時源選擇策略,對關(guān)聯(lián)時源的品質(zhì)輸出進行了分析;在守時算法方面,提出了基于余數(shù)動態(tài)分攤的自適應(yīng)精確守時算法,并分析了晶振參數(shù)對守時精度的影響;在動態(tài)調(diào)整方面,提出了基于硬件實現(xiàn)的頻率與相位實時跟蹤方法,當外部時源與本地時源相差較大時,本地時源頻率與相位以小步長勻速逼近外部時源,并趨于穩(wěn)定。試驗證實,所提方法在守時精度與相位和頻率動態(tài)調(diào)整方面取得了較好的效果,實現(xiàn)了時間的高穩(wěn)定性輸出。
[Abstract]:In order to realize the high stable output of the time synchronization device, this paper puts forward the methods and implementation steps for the three key links of multi-time source selection, punctuality algorithm and dynamic adjustment. An external independent time-source selection strategy based on clustering algorithm is proposed, and the quality output of associated time-source is analyzed. In the aspect of time-keeping algorithm, an adaptive accurate time-keeping algorithm based on dynamic allocation of residue is proposed. In the aspect of dynamic adjustment, a real-time tracking method of frequency and phase based on hardware is proposed, when the difference between external time source and local time source is large, The frequency and phase of the local time source approach the external time source at a small step, and tend to be stable. Experiments show that the proposed method has achieved good results in terms of timing accuracy, phase and frequency dynamic adjustment, and achieved high stability output of time.
