Design of Measurement System for the Pressure Reducing Valve of Attitude System Engine

摘要:

介绍了一种基于PC-104的姿控发动机减压阀性能测试系统设计,包括其系统测试原理、硬件结构和软件结构,重点介绍了基于Delphi的应用软件的开发。通过采用动态链接库、多线程、虚拟设备驱动程序等技术提高了测试系统的实时性和稳定性。

Abstract:

The development of measurement system based on embedded PC-104, including the theory of measurement, the frame of hardware and the frame of software, for the pressure reducing valve of attitude system engine was introduced, and the design of software based on Delphi was introduced emphatically. The real-time and stability of the measurement system was improved by using Dynamic Link Library, multi-thread and VxD.
