Design And Implementation Of A Automatic Biochemistry Analyzer

The Automatic Chemistry Analyzer is one of the important analyzer machine using in clinic examination,which measure various kinds of the chemistry indexs by the analyzer to blood or other body fluid. As the rapid improvement of the automatization of hospital, all kinds of advanced Chemistry Analyzer appear. Recently as the continuous development of the sience, especially the computer technique and electron technique,The Chemisty Analyzer grow rapidly in structure and performance.The traditional Chemistry Analyzer is always autoloading. The disadvantage is low performance and stability, simple function and little io resources, which causes falling behind the rapid development of the Chemisty Analyzer.This paper Realize the ADC sample system of multichannel and high precision, improve the front light-sample system. Offers the scheme based on high performance DSP and use CPLD to control the logic. Complete the interface and electrical machine system. Design and realize the application software of signal measure and control system. Improve the io and memory resources. Complete the soft and hard circuit debugging and testing. Complete the installation and debugging of the software and hardware.Through the test result, the design realizes the scheduled request and ensure the stability of the system. The system is rational and feasible. And the new system has abundant resources, good expansibility, and convenient maintenance and debugging interface, which establish good base for the following upgrade. Also this paper can offer references to the relevant development.
