机载公共设备综合管理仿真平台的时钟同步

Clock Synchronization for Simulation Platform of Aircraft Utility Management System

机载公共设备综合管理系统是一种必然趋势,建立机载公共设备综合管理系统分布式仿真平台,设计软硬件结构,使之具有余度、重构、故障容错和可扩展性的功能,时钟同步是其中一个关键技术,1553B总线固有的时钟同步技术实现基本的功能,主从式的概率时钟同步技术实现进一步的调整,1553远程终端到远程终端广播周期消息通信实验有效实现发送和接收端的时钟同步,解决分布式实时控制系统中节点的时钟同步问题。

To provide an integrated management system for the aircraft utility systems is an inevitable developing trend. The distributed simulation platform of the aircraft utility management system （UMS） was developed. Its hardware architecture and software structure were designed to possess the function of redundancy, reconfiguration, fault-tolerance and extendability. The clock synchronization is a key technology in it. The clock synchronization technology provided by 1553B-bus own self actualizes the fundamental function. The master-slave probabilistic clock synchronization technology carries out the farther adjustment. The communicate experiment of broadcasting periodic massages from Remote Terminal （RT） to RTs on 1553B bus achieves clock synchronization of the transmitter RT and the receiver RTs and resolves clock synchronization of the nodes in the distributed real time control system.
