Definitions

  • Time compensation is performed according to the obtained one time offset such that the slave clock is synchronized with the clock of each clock server.
  • the Offset represents the time offset
  • T4 represents the time when the clock server sends the delayed response message
  • T3 represents the time when the second collection unit sends the delay request message
  • T2 represents the first collection.
  • T1 represents the time when the clock server sends the synchronization message.
  • a storage medium is also provided.
  • the storage medium is arranged to store program code for performing the following steps:
  • step S12 the slave clock interacts with multiple clock servers to collect time data provided by multiple clock servers.
  • the specific collection process is shown in Figure 3:
  • the multi-clock server synchronization mode is adopted, so that the slave clock can simultaneously exchange messages with multiple clock servers, and collect data provided by multiple clock servers, thereby speeding up data collection and greatly shortening.
  • the clock is locked for a long period of time and does not need to be deployed on multiple clock servers. This facilitates flexible deployment of the clock server. Switching between the active and standby clock servers can also achieve smooth processing.
  • the LTE base station and the two 1588 clock servers exchange packets through the corresponding clock link, and collect time data provided by two 1588 clock servers.
  • the LTE base station receives the synchronization message sent by the 1588 clock server 1 and the 1588 clock server 2, acquires the transmission time T11 and T21, and records the reception time T12 and T22.
  • the LTE base station compensates for the time offset to synchronize the LTE base station with the clocks of the two 1588 clock servers.
  • the time of the response message T3 represents the time when the delay request message is sent from the clock 100, T2 represents the time when the synchronization message is received from the clock 100, and T1 represents the time when the clock server 300 transmits the synchronization message.
  • the time offset is compensated from the clock 100.
  • the PID control algorithm is used to process multiple time deviation data in different control states to obtain PID control parameters and a time deviation data; the voltage control voltage is calculated according to the PID control parameters; The voltage control voltage adjusts the crystal frequency so that the slave clock 100 synchronizes with the frequency of each clock server 300; time compensation is performed based on the obtained time offset data, so that the slave clock 100 is synchronized with the clock of each clock server 300, thereby keeping the slave clock 100 Frequency and phase consistent with clock server 300 time.
  • the slave clock 100 sequentially switches in three control states of free running, fast catching, and locking according to different time deviation data.

Abstract

L'invention concerne un procédé et un dispositif de synchronisation d'horloges. Le procédé comprend les étapes suivantes : une horloge esclave configure des paramètres de synchronisation d'horloge sur la base d'au moins deux serveurs d'horloges, les paramètres de synchronisation d'horloges comprenant au moins deux liaisons d'horloge, toutes ayant un intervalle de paquets identique ; l'horloge esclave échange des paquets avec chaque serveur d'horloges au moyen de la liaison d'horloge correspondante pour acquérir des données de temps fournies par chaque serveur d'horloges ; l'horloge esclave calcule une différence de temps entre chaque serveur d'horloges et l'horloge esclave, conformément aux données de temps acquises, et compense les différences de temps multiples afin de réaliser une synchronisation d'horloges entre l'horloge esclave et chaque serveur d'horloges. A l'aide d'un mode de synchronisation de plusieurs serveurs d'horloges, une horloge esclave peut échanger des paquets avec plusieurs serveurs d'horloges en même temps, de telle sorte que l'acquisition de données est accélérée et la durée pendant laquelle une horloge est verrouillée est considérablement raccourcie, ce qui facilite ainsi un déploiement flexible des serveurs d'horloges et réalise une commutation lisse entre serveurs d'horloges maîtres et esclaves.
