PAGE PAGE I 基于虚拟仪器全自动生化分析仪的研究 The research of full automatic biochemistry analyzer based—on Labview 摘 要 全自动生化分析仪是典型的光、机、电、算结合的精密仪器，涉及的学科门类多、技术复杂，其中的分光光度计是该仪器的核心部分之一，它的优劣直接影响仪器的精度指标。 本论文首先阐述了生化分析仪国内外的发展状况，介绍了生化分析仪的工作原理；依据全自动生化分析仪的控制任务情况，以一台系统机为上位机、以8051单片机构成下位机系统，完成了控制系统的硬件电路设计;依据全自动生化分析仪的功能要求，完成了软件设计，上位机主控软件采用具有强大功能的图形化编程语言Labview、下位机采用汇编语言完成;最后将数据在上位机显示，结果表明本控制系统可以满足全自动生化分析仪的控制要求。 关键词：生化分析仪 光度计 虚拟仪器 控制系统 单片机。 Abstract Full automatic biochemistry analyzer is a kind of typical Fine Instruments which is composed of Optic, Mechanic, and Electric. It contains lots of academics and the skills are complex. The spectrophotometer is a crucial component. Its performance will affect the performance of entire system. Firstly, the national and international development of automatic analyzer is introduced in this paper. The principle of the automatic analyzer is introduced. According to the multitask need of mechanical movement, a multi-CPU control system consisted of one PC computer and 8051 single-chips is designed. According to the need of operation, a software system with good interface and strong function is completed .The PC program is based on LABVIEW language and the program in 8051 is based on assemble language. The reliability of this control system is also discussed in this article. At last the result is displayed on the PC program. The results indicate that the control system fit the bill of the analyzer. Key words: automatic analyzer, photometer, Labview, control system, single-chips 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc137779757 第一章 引 言 PAGEREF _Toc137779757 \h 1 HYPERLINK \l _Toc137779758 1. 1 生化分析仪 PAGEREF _Toc137779758 \h 1 HYPERLINK \l _Toc137779759 1. 2 分光光度计 PAGEREF _Toc137779759 \h 2 HYPERLINK \l _Toc137779760 1. 3 生化分析仪的国内外发展状况 PAGEREF _Toc137779760 \h 4 HYPERLINK \l _Toc137779761 1.3. 1 国外发展状况 PAGEREF _Toc137779761 \h 4 HYPERLINK \l _Toc137779762 1.3. 2 国内发展状况及市场需求 PAGEREF _Toc137779762 \h 5 HYPERLINK \l _
