摘　　要：随着现代导航技术的发展,惯性导航作为一种自主导航技术已经广泛应用于多种武器系统中,而导航计算机又是捷联式惯导的核心部件。文章提出了一种采用基于DSP的某型导航计算机模块的解决方案,设计方案采用双处理器TMS320C6713,对数字电路接口实现了光电隔离,采用FPGA实现对多路信号的核心处理,并具有CAN总线通信接口。本文对计算机单元的硬件设计与实现方法进行了较为详尽的描述。该计算机单元满足了某型武器惯性导航系统的使用需求。With the development of modern navigation technology, inertial navigation as an autonomous navigation technology has been widely used in a variety of weapon systems, while the navigation computer is the core component of strapdown inertial navigation system. This paper presents a DSP-based solution to a certain type of navigation computer module. The design uses dual processor TMS320C6713, digital optical isolation circuit interface, FPGA core to multi-channel signal processing, and has a CAN bus a communication interface. In this paper, hardware design and implementation of the computer unit has a more detailed description. The use of the computer board meets the needs of a certain type of weapon with inertial navigation systems.
