摘　　要：介绍了一种基于ARM7芯片SEP3203的嵌入式半自动生化分析仪,辅以一片PIC单片机作为协处理器。给出了仪器的工作原理。系统硬件电路由存储器子系统、液路子系统、温度控制模块、吸光度采集模块、人机交互模块等模块组成,详细描述了各硬件模块的设计。分析了软件系统的设计。该新型生化分析仪使用方便,性价比高,适用于国内的中小型医疗机构。A Semi-automated clinical chemistry analyzer based on SEP3203 ,an ARM7 Micro-controller, is introduced in this paper. A PIC single chip microcomputer is used as a coprocessor. The operational principle of this machine is presented. It is composed of memory subsystem, liquid lane subsystem, temperature-control module, acquisition of absorbance module and man-machine interactive module. The designs of modules are expatiated in detail. The design of the software system is discussed at the same time. This new clinical chemistry analyzer can be used conveniently, with high performance and low price. It is fit for medium and small medical institutions.
