基于VME总线的LINS系统设计

Design of LINS based on VMEbus

针对多任务并行实时处理、中等精度、性能可靠的要求,提出了一套基于 VMEbus 总线的分布式并行双机的环形激光陀螺捷联惯导系统(LINS)的设计方案,方案的实现使得硬件上满足实时化、易开发的特点.软件的设计符合软件工程的设计思想,同时又解决了系统的同步及 PCI 与 VME 总线的中断与访问。

This paper put forward a design of Laser inertial navigation system(LINS)with middle precision,real- time multitask parallel processing.steady and reliable performance.The design of this LINS is based on VMEbus and parallel distributed processor.The hardware implementation made the system have the character of real-time and can be developed easier.The software design is according to software project theory.The problem of event time synchronization and interrupt between PCI and VMEbus is solved.
