| 摘 要： | 单独采用PC104不能很好的实现多传感器的数据采集和导航解算双重任务,本文基于PC104的堆栈式结构,以TI公司TMS320F28335浮点DSP为核心处理器设计了一款双CPU、分布式、小型化的导航计算机。通过PC104总线扩展MOXA多串口卡实现微惯性测量元件MIMU和GPS的数据采集,而在DSP中完成导航算法和组合导航参数的解算。PC104与DSP之间的高速数据通信通过扩展双端口RAM实现,系统地址的逻辑选通和时序的控制通过CPLD实现

| Abstract: | The dual-task of multi-sensor's data-sampling and navigation solution could not well be realized by the single PC104.Based on the stacked structure of the PC104, a new kind of distributed, small-sized and double-microprocessor navigation computer system was designed in this paper, and took the floating Digital Signal Processor TSM320F28335 as the core.Data-sampling of the MIMU and GPS was realized by the extended multi-serial board of MOXA based on the PC104 bus while the algorithm of navigation and solutio... |
