| Automatic biochemical immune analyzer, one of large-scale medical inspectionequipment, is most widely used in the area of clinical laboratory diagnosis, which is related tooptical-electro-mechanical system. The equipment is mainly used to replace the originalmanual operation with automatic operation in the process of sample and reagent, incubation,oscillation, washing board, testing, the results of calculation and displaying and so on. It canreduce the error caused by subjectivity of operators, ease the work load for operators andimprove the work efficiency in the numerous sample testing projects. Automatic biochemicalimmune analyzer mainly includes the following several modules: liquid injecting systemmodule, mechanical arm transportation system module, incubation oscillation system module,wash machine system module and test analyzer system module. Therefore, this paper mainlyencounters difficulties in system integration and design of software system. The controlscheme of the whole system consists of three parts: PC, motion control card and STM32. ThePC realizes the human-computer interface of control system and communicates with lowermachine. The motion control card controls the motion of injecting arm and mechanical armand STM32acquires data in operating process. Based on the windows operating system andthe Microsoft c#language, the software system is designed by using object-orienteddevelopment technology in the Visual Studio2008environment.The main contributions of this dissertation consist of the following parts:(1).The present situation and performance of similar products home and abroad havebeen researched. Based on the domestic existing technology and craft level, the functionalrequirements and performance requirements of the automatic biochemical immune analyzerare presented.(2).The operation process and performance index of the automatic biochemical immuneanalyzer is studied and then summarized. Finally, the overall system is designed from twoaspects of hardware and software.(3).In view of the multi-tasking optimization scheduling problem existed in theautomatic biochemical immune analyzer, the optimal scheduling model with its constraints and objective function are established. At the same time, an improved ant colony algorithm isproposed to obtain the optimal scheduling scheme. Finally, its feasibility and effectiveness isdemonstrated through the simulation.(4).Firstly, the software development method and design requirements are introducedbriefly, and the system software modules are especially analyzed. Then functions of eachmodule are realized by using object-oriented technology, ADO.NET database technology,multi-threading technology and Microsoft c#language based on the windows operatingplatform and Visual Studio2008.(5).After completing the software system implementation of automatic biochemicalimmunity analyzer, the overall system is tested and joint-debugged in order to improve thefunction and performance of software system. |
