飞机弹射筒弹射过载信号采集仪的研究与开发

Study and Development of Acquisition Device on the Acceleration for Testing Ejection Guns

针对国内飞机弹射筒地面弹射试验的试验情况,开发一套基于C8051F120单片机的弹射筒弹射过载信号采集仪。介绍该系统硬件和软件的设计方法及工作原理,重点对系统电路的设计进行论述并基于PROTEUS7.6平台进行电路仿真;软件开发基于LabWindows/CVI虚拟仪器平台,功能合理,人机交互好。应用结果表明,该采集系统运行稳定可靠,精度高,具有一定的实用性和推广价值。

Concerning on the testing condition on testing ejection guns of aircraft on ground, an acquisition de- vice on the acceleration based on C8051F120 MCU is developed. The hardware design, software design and op- erating principle for the system, with the emphasis on the design for the circuit discussed and circuit simulation based on PROTEUS7.6, are briefly introduced; the software is designed based on LabWindows/CVI Virtual instrument platform, which reaches a function reasonable and a good man-machine interface. The application shows that this system runs stably and accurately. The technology and methods adopted in the system are prac- tical and worthy of popularization.
