液体火箭发动机试验测量系统状态检测程序设计

Design of the state detection program of the measurement system for liquid rocket engine test

发动机试车准备过程中,测量系统的状态变化直接影响到发动机参数测量的准确度。为正确获得测量系统的状态变化,从测量系统的硬件组成出发,针对压力、温度等参数类型,提出了测量通道状态变化的检测判断方法。在Windows操作系统下,采用VB6.0语言,设计了相应的状态变化检测程序。试验证明:测量系统状态检测程序运行可靠,操作方便,提高了试车工作效率。

Accuracy of the engine parameters measured strongly depends on the status of the measuring system. The methods for detecting the status of the measuring channels for pressure and temperature were proposed in this paper considering hardware configuration. The status detection program of the measuring system is designed under Windows operation system in VB6.0. It is proved that the program is reliable with friendly interface and high efficiency also obtained.
