基于NTP的装备管理信息系统时钟同步技术研究

摘要

In order lo solve the problem of the terminal collection information's time difference in equipment management information system .with the analysis of the GPS timing theory and the network time protocol (NTP). A project of the clock synchronization of e-quipment management information systems based on the GPS and NTP is put forward. The GPS time is regarded as the system's standard time,combined with NTP to implement the clock synchronizing of the information collection terminals and the time consistency of ail the system's information.%为了解决装备管理信息系统中各分布式信息采集终端采集信息的时间差异问题,在对GPS授时原理和NTP网络协议进行分析的基础上,提出了基于GPS和NTP的装备管理信息系统的时钟同步技术方案,将GPS时钟作为系统的标准时间源,结合NTP协议对各信息采集终端进行时钟同步,从而实现了维持系统各信息时间一致性的目的.
