| Abstract: | 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. |
