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 a kind of autonomous navigation technology has been widely used in many kinds of weapon systems, and navigation computer is the core component of strapdown inertial navigation. This paper presents a solution based on DSP using a certain type of navigation computer module. The design adopts dual processor TMS320C6713, which realizes optical isolation on the digital circuit interface. FPGA is used to realize the core processing of multi-channel signal. And it has CAN bus Communication Interface. In this paper, the computer unit hardware design and implementation of a more detailed description. The computer unit fulfills the operational needs of a type of inertial navigation system for weapons.
