Bus And Embedded Technology-based Torpedo Guidance System

Torpedo Guidance and Control System (TGCS) is an important part of torpedo whose performance is fine or inferior will directly influence torpedo's battling performance. Now, the system architecture of TGCS mainly use the Central Control System (CCS), but modern war needs that torpedo ought to have higher performance, especially further voyage, higher maneuverability. They bring all kinds of message and connecting mode. So, for traditional CCS, responding timely and exactly to the event of torpedo's parts will be comparatively hard. In this dissertation, we, firstly, research the system architecture of TGCS, Field bus and embedded technology deeply. And then we project the system architecture of TGCS based on bus and embedded technology. According to analysis and demonstration, we design principle prototype in the laboratory which contains three CAN nodes: two microcontroller node and one central processing computer (CPC) node.In this dissertation, we analyze and design the principle prototype by way of hardware system and software system. For hardware system, the microprocessor of Microcontroller node is AT89C52 and CPC node is TMS320LF2407 DSP. They manage the hardware module severally. For software system, Microcontroller node use Assemble language to program software module. CPC node use μC/OS-Ⅱ as its operating system. Hardware drivers and application programs are developed based on μC/OS-Ⅱ. Finally, we discuss the design about the debugging software of upper machine which will help to develop the debugging software of torpedo in future.According to last debugging of system jointly, this principle prototype reaches the purpose of design. This production will be important technical storage for next generation full digital torpedo.
