【摘要】 鱼雷制导系统是鱼雷的重要组成部分，其性能的好坏直接影响到鱼雷的整体作战性能。目前的鱼雷制导系统大多还采用集中式控制的体系结构，已经难以满足现代数字化鱼雷对于外部响应要求高实时性和对信息处理种类、信息处理量日渐增多的要求。因此，论文在分析了当前鱼雷制导系统现状和嵌入式及总线技术的基础上，提出了一种基于嵌入式和CAN总线技术的开放式鱼雷制导系统体系结构，这种结构可以很好地解决目前集中式控制体系结构的不足。 论文首先提出了开放式鱼雷制导系统的概念并建立了其体系结构框图。在对嵌入式技术的研究当中，重点研究了嵌入式操作系统μC／OS-Ⅱ和VxWorks，特别对嵌入式操作系统VxWorks向ARM芯片S3C2410的移植进行了研究，在此基础上确定了开放式鱼雷制导系统嵌入式软硬件平台。在研究CAN总线技术时，论证了CAN总线应用于开放式鱼雷制导系统的可行性，在CAN协议的基础上重点对鱼雷制导系统的CAN总线应用层协议进行了研究，并设计了一个简单的鱼雷应用层协议，最后分析了鱼雷制导系统中CAN总线的实时性。以主控制器节点为代表研究了开放式鱼雷制导系统中的节点设计，给出了主控制器节点的结构设计。最后研究了对CAN总线进行改进的时间触发总线——TTCAN，对TTCAN在鱼雷制导系统中的应用进行了初步研究。论文的研究成果可以作为下一代全数字鱼雷的重要技术储备。更多还原

【Abstract】 Torpedo Guidance and Control System(TGCS) is an important part of torpedo ,whose performance will directly influence torpedo’s battle performance. Now the system architecture of most TGCS still uses the Central Control System(CCS), which can’t meet the requirements of modern digital torpedo that is the high real time for external response and the gradually increasing kind or number of data. So,the thesis puts forward a kind of open TGCS architecture bases embedded and CAN bus technology after analyzes present condition of TGCS and embedded and CAN bus technology,it could solve the deficiencies of present CCS well.The thesis firstly introduces the idea of open TGCS and establishes its architecture map. In the course of studying embedded technology, the thesis mainly studies the embedded OS μC/OS- Ⅱ and VxWorks, especially studies the import of embedded OS VxWorks to ARM microprocessor S3C2410, and finally design the software and hardware platform of open TGCS. When studies the CAN bus technology, the thesis demonstrates the feasibilities of CAN bus could be used into open TGCS, specially studies CAN bus application layer protocol of TGCS based on CAN protocol and design a simple torpedo’s application layer protocol, at last analyzes the real-time quality of CAN bus in TGCS. The thesis studies the node design of main controller as a representative of all nodes in open TGCS and designs the architecture of main controller node. The whole thesis finally studies the TTCAN which improved CAN bus, and makes a primary study on TTCAN using into TGCS. The production of thesis will be important technological references for the next generation full digital torpedo.更多还原
