摘要
通过采用冗余对时服务器同GPS时钟源定期对时,与带时钟修正功能的局域对时系统相结合的方式实现高精度对时,并采用多组对时服务器实现了冗余功能。经济可靠地实现了大中型分散控制系统的对时功能。
Implement high precision clock synchronization by synchronizing redundant time server with GPS source regularly and adjusting clock in local sync system. And implement redundancy with multiple time servers. Make the time sync function of large DCS system economic and robust.
