【摘要】 本文首先介绍了生化分析仪作为一种智能仪器的研究现状和发展前景,接着介绍了生化分析仪的生化分析基础——光学中的朗伯—比尔定律,然后重点介绍我的课题所设计的用PC机作为分析仪的上位机软件系统,用单片机89C52为核心的下位机硬件系统,通过定义上下位机的通讯协议,让上位机向下位机发送指令来控制分析仪下位机完成分析操作,上下位机之间通过RS232总线来进行通讯。整个分析控制系统包括了上位机的软件设计,生化分析仪下位机硬件控制电路设计及下位机软件控制部分编程。在最后的部分介绍了几种生化分析测试方法和分析了用生化分析仪进行实际测试分析的误差产生来源以及反馈试验数据分析。更多还原

【Abstract】 This paper first describes the research status and prospective development of bio-chemical analyzing instrument as an intelligent instrument, then introduces the theoretical base—Lambert-Beer Law in Optics. In the following Chapters, the paper presents the whole system design of this project as follows:It uses common PC as the superior computer system and single-chip computer 59C52 as the core of the whole inferior computer system, by defining the telecommunication protocol, which ensures the regular transmission between the superior and inferior computer system, we can control the completion of bio-chemical analysis by letting superior computer system transmit command to inferior computer system. We adopt RS-232 bus as the linkage of superior computer system and inferior computer system.The whole system includes the software design of the superior computer system and the hardware and software design of inferior computer system as well. In the last part of this paper, several ways of bio-chemical analysis is presented and the error source produced in field operation is presented.更多还原
