摘　　要：研究的寻北导航系统主要以动力调谐陀螺为敏感设备,创新地采用TMS320VC5402芯片作为主处理器构建寻北仪的计算机系统,取代通常构建系统时所用的PC机或单片机,并以CPLD为主要控制辅助组件设计并调试数据的采集、处理、输出、信息通信等硬件电路和相关软件,充分利用DSP快速运算、信息存储、逻辑判断和数据处理等能力完成多种控制任务,在实现寻北功能的同时又使系统的精度、控制和解算能力得到提升。The north-seeking navigation devices were mainly equipped with DTG as sensitive equipment and innovated in the use of DSP 5402 as the main processor to construct the computer platform of the north seeker instead of PC processor or single chip which were used to construct the system. And the CPLD displayed as the main assistant element in charge of control, and debugged the hardware and software consisting of data collection, processing, output and the communication. Achieving multi-task of controlling by utilizing the ability of fast operation, information storage, logical judgment and data processing of DSP and so on. It realizes the goal of north-seeking and advances the ability of precision controlling and operation in the system at the same time.
