The Design and Implement of Automatic Analyzer for Rocket Propellant

文章采用内嵌单片机方式和电位滴定原理,设计实现了火箭液体推进剂自动分析仪。系统采用了二次微分法求终点,提出并实现了通过阈值判断和相关分析滤除假终点的方法,解决了电位滴定过程中终点难以判断的问题。

In this paper,the automatic analyzer for liquid propellant of rocket is designed and implemented on the principles of embedded single chip computer and constant -current titration.The system uses the method of quadric differential coefficient to get the end point,puts forward and implements the method of eliminating false end points through the threshold value judgments and the correlative analyses,solves the problem that the end point is difficult to judge in the process of constant-current titration.
