The Soft System Integration Of Portable Plasmon-Enhanced Raman Spectroscopy Instrumentation

Raman spectroscopy has an important application prospect in the field of chemistry, safety inspection, biomedical analysis. The subproject "PERS instrument systems integration" in major national scientific equipment developed special needs to address issues on portable Raman spectrometer with automated control, database, data analysis, and user interface. The main work in this paper is carried out on its soft system integration design and development.This paper proposes a method to build software systems integration, based on object-oriented software engineering. C++programming language and MFC are used to realize portable plasmon-enhanced Raman spectroscopy spectrometer soft systems integration in VS2010development environment. The main work includes:(1) Analysed the soft system requirements and compiled the "software requirements specification", according to the mission statement of the project requirements and the needs of users and engineers in terms of soft system functionality, performance and security.(2) Made a preliminary design of the entire soft system, which is split into four subsystems. Made functionality detailed design in four subsystems.(3) Compliance with coding standards, wrote code to implement functionality using C++language. Designed and realized human-computer interface.(4) Tested each subsystem features and functionality of the entire software system, using white box testing method and black box testing method, to eliminate errors of the soft system to meet users’needs.(5) Applied the soft system to actual measurement system to get the actual test results.The main innovation lies in the software system provides a wizard for Raman test analysis. In the wizard dialog, users can select a category and a specific measurement system of the measuring system. After the specific measurement system is selected, the guide frame dialog will pop up, which gives intelligent guidance. No matter the users are professional or not, they could complete Raman test and obtain analytical results of the measuring system in accordance with the guide frame dialog. Currently, the soft system has been applied to detection module in the PERS I and PERS II type instrument. And the soft system has been applied to the actual measurements, such as malachite green system, arsenic system, pigment system, etc., which achieves the ideal test results.
