Improve On The Fiber-Capacitive Drop Analyzer

The fiber-capacitive drop analyzer (FCDA) is based on a specially designed drop sensor by means of the fiber drop analyzing technology and the capacitive drop analyzing technology, and produces a volume-based fiber drop trace (VFDT), which shows the relation between the light intensity passing through the liquid drop and the instant drop volume. Using this principle, we are able to achieve the precise liquid measurement differentiations, as well as liquid detection for environmental protection, manufacture works, food and beverage regulations etc.The project is supported by the NSTB-MOST Joint Research Program (Project Number: 003/101/04), where NSTB refers to the National Science and Technology Bureau of Singapore and MOST refers to the Ministry of Science and Technology of China. This project aims to make the drop analysis experimental device become a practical instrumentation and to make some analysis of the experimental results of typical samples. Instead of building complicated database, we focus on some typical samples, which have scientific and economical values. Then we finished the software which could distinguish these liquids, and finally, have a nice outcome in the experiment results.The work of this thesis includes:(1) Designed the embedded controlling system.(2) Finished the softeware which could distinguish the tiny distinction between the two liquids.(3) Transplanted the software from Win32 plantform to Arm-Linux plantform.(4) Verified the reliability of the software by means of experimentation.
