【摘要】 介绍了一种基于DSP设计的捷联惯性制导系统。应用TI公司的TMS320C6711DSP器件为系统的核心,采用压频转换进行惯性器件信号采集,利用CPLD实现系统所需要的逻辑电路功能,并对系统硬件平台的方案设计和软件设计进行了分析。分析结果表明,系统满足了捷联惯性制导在数据处理能力并且具有结构简单、可靠性高等特点,克服了传统的X86系统可靠性差、复杂、功耗大等缺点。更多还原

【Abstract】 The DSP-based strapdown inertial guidance system is introduced.TMS320C6711 is selected as the core of system.Voltage-to-frequency converter(VFC)is used to gather the inertial device information. CPLD is adopted to realize logic circuit,and system’s hardware platform and software platform are also analyzed.The results show that the precision and requirement of realt-time are satisfied,and this system has simple structure,good reliability and practical value;forthermore,the shortcoming of traditonal X86 system is overcome.更多还原
