摘　　要：针对武器装备远距离有线通信应用场景,提出了一种基于VDSL2的以太网通信及同步方法,实现了以太网数据和同步脉冲信号在长距离双绞线上的同传,利用基于反馈和鉴相的脉冲调理方法解决同步脉冲信号长距离传输的延迟和畸变问题,完成了基于CPLD的同步调理模块设计。该通信及同步方法可为武器装备远程通信及同步设计提供参考。Aiming at the application scenario of long-distance wired communication for weapon equipment, a VDSL2-based Ethernet communication and synchronization method was proposed, which realizes the simultaneous transmission of Ethernet data and synchronous pulse signals on long-distance twisted pair. Aiming at the delay and distortion of long-distance transmission of synchronous pulse signals, a pulse conditioning method based on feedback and phase discrimination was proposed, with the design of synchronous conditioning module based on CPLD completed. The communication and synchronization method can provide references for the design of long-distance communication and synchronization of weapon equipment.
