为提高导弹测试设备的专业化、模块化、通用化设计,提出了一种基于FlexRay总线技术的便携式通用测试设备的设计方法,并实现了以MFR4200和TJA1080为核心的总线接口电路设计和相应的软件开发；根据该方法设计的测试设备成本低、可靠性高、使用灵活,能够满足苛刻环境下对武器装备的测试需求,是目前常用的基于PCI、PXI等总线测试设备的良好补充.%A method to design portable general testing equipment of missile is presented in this paper. The method is based on the tech-nology of FlexRay bus. Meanwhile, it includes bus interface circuit with a core of MFR4200 and TJA1080. It is applicable to specialize, mod-ularize and generalize the design process of missile testing equipment. The missile testing equipment by this method is low -cost, reliable, and flexible to meet the operating requirements in harsh environmental conditions. It is a favorable complement to common testing equip-ments based on PCI/PXI bus.
