摘　　要：嵌入式系统已越来越多地应用于军用训练模拟器,可为提高军用训练模拟器的仿真度和可靠性提供有力的技术支撑。军用训练模拟器嵌入式系统设计具备通用嵌入式系统设计的共性要求,也有其特殊要求。对军用训练模拟器嵌入式系统的设计要求进行了分析,重点对元器件、硬件、软件等三方面的可靠性设计进行了深入分析研究,并提出了相关的应对策略。其中,对于元器件可靠性设计,分析了其失效类型、失效原因及可靠性保证策略;对于硬件的可靠性,重点对印刷电路板各环节的可靠性设计进行了分析研究;对于软件可靠性,阐述了嵌入式软件的故障特点、原因及可靠性策略。Embedded systems have been increasingly used in the Military Training Simulator,providing the powerful technical support to improve the fidelity and dependability of MTS,for which the design of embedded systems has the same requirements as the general embedded systems,having special ones.The design requirements of embedded systems for MTS were analyzed,giving a deep research on how to achieve the high dependability in terms of the electrical component,hardware and software,and accordingly providing some practical approaches.In terms of the design of the dependability of electrical component,the types and reasons of failure were analyzed as well as the guaranteed strategies for dependability.For the hardware,the research,focusing on the dependability design of PCB in every segment,was made.For the software,lastly,the characteristics of failure,reasons and some relative strategies were illustrated.
