摘　　要：围绕某型号姿控动力系统减压阀性能测试需求,提出一种基于PC104总线测试架构的设计方案。详细阐述了减压阀性能测试原理、硬件设计方案和软件开发思路,着重介绍了软件开发需求、总体架构、用户程序开发思路和软件设计关键技术等。实际应用表明,该系统操作简单、携带方便,测试精度优于0.2%,控制定时精度优于1 ms,满足减压阀性能测试要求。A design scheme based on PC104 bus testing architecture is proposed to meet the needs of performance testing system for the relief valve of an attitude control engine. The performance testing principle, hardware design scheme and software developing idea of the relief valve is described in detail. The demands of Delphi software development, overall architecture, dynamic database linking and key technology of software design are elaborated. The actual application of this equipment indicates that the system can meet the requirement of the relief valve performance testing. It has simple operation, high accuracy and high reliability.
