Study On Data Processing In Chromatography Workstation

Under the background of the development of the on-line chromatography workstation ,we have developed the on-line chromatography analysis system, including hardware architecture design, software and communication, and finished it under the windows platform at last. According to the regularities of software engineering,we use the technology of the Oriented Object Programming and divide the whole system into several functional modules. The system was consisted of two parts, the upper computer and the down computer. All work was finished at the upper computer except sampling and valve activity,such as the system control, the parameter changing on-line, the signal processing, the peak recognition, the result outputting, and so on. The needed time and energy for designing and compiling them are great. Especially it took a lot of energy and time to explore and realize the communication, the system state control and the parameter changing on-line,ect.According to the regularities of software engineering , this thesis introduces the system development in detial.Firstly, by reviewing the up-to-date research in the world and in our country, the developing trends of the Analytical Instruments have been pointed out ; then the project in this report came up naturally, that is to say, it has the necessity and probability to develop the system under the Windows platform. After introducing the background of the project and analyzing the necessary performance of the system,we come up with the general logical module. Following that ,we introduce the general structure and each functional modules and the methods to realize them in detail. With the deeply discussion on the technology used in the developing process and the diffult points in the system development, we also show the difficulty and complexity of these project in the thesis. Being analyzed the problems encountered to during the system executing, the aspects that should be improved in the future have been pointed out. At last the experimented results show that the system performs very well.
