摘　　要：时钟同步技术应用于无人战车是目前无人战车实时性的发展趋势。通过分析无人战车中对于时钟同步技术的需求,以及比较用于无人战车的主要时钟同步技术协议IEEE 1588、SAE AS6802和IEEE 802.1AS,提出将AS6802中的容错机制增加到IEEE802.1AS中,即将时钟监测技术、路径冗余技术和主时钟冗余技术应用到IEEE802.1AS中,最终实现在保持高精度时钟同步,提高其可靠性。The application of clock synchronization technology in unmanned combat vehicles is currently the trend of real-time development for unmanned combat vehicles.By analyzing the requirements for clock synchronization technology in unmanned combat vehicles and comparing the main clock synchronization technology protocols used in unmanned combat vehicles,such as IEEE 1588,SAE AS6802,and IEEE 802.1AS,it is proposed to add the fault-tolerant mechanism in AS6802 to IEEE 802.1AS,the clock monitoring technology,path redundancy technology,and master clock redundancy technology are applied into IEEE802.1AS,ultimately while high-precision clock synchronization is achieved,its reliability is improved.
