摘要
以实际科研项目为背景,研究了基于DSP+单片机主从式双CPU结构的组合导航系统,可以兼顾导航系统数据I/O功能和运算功能,并且实现两者合理的分配。单片机实现外部多传感器的数据采集,DSP对所采集的数据进行数据运算和处理,同时采用双口RAM共享数据的方式保证双CPU间高速的数据通信。最后通过跑车实验,验证了导航计算机可以有效的融合多传感器的导航信息,达到运载体导航定位的精度和性能要求。
This paper develops an intergrated navigation system based on DSP＋MCU master-slave dual CPU architecture,at the background of an actual scientific research,which can realize the function of navigation system data I/O and computing to achieve a reasonable distribution of them.MCU can acquire the date from external multi-sensor,then the task of DSP is to compute and process,while using dual-port RAM to ensure high speed data communication between two CPU.Finally,through an experiment of running car,ensure that navigation computer can fuse multi-sensor navigation information efficiently.
