摘　　要：智能通信板主要用于舰载电子设备的通信,针对其高可靠性、可用性、可维护性的要求提出一种基于PIC-MG2.9规范的智能通信板可测试性设计方案,分析故障模式并提出故障诊断策略以降低故障诊断时间和降低虚警率。故障模拟测试结果表明,设计达到系统指标要求。Intelligent communication board is mainly used for communication between ship - borne electronic equipment. In order to enhance the reliability, availability and serviceability, a kind of DFT technique design based on PICMG2.9 specification is proposed. Aiming at reducing fault detection time and false alarm rate, the fault modes are analyzed and a diagnosis strategy is proposed. The design is proved eligible by fault emulation.
