基于DSP的半自动生化分析仪设计

Design of Semi-automated Biochemistry Analyzer Based on DSP

介绍了一种基于数字信号处理器(DSP)的半自动生化分析仪。该分析仪以TI公司的TMS320F2812为系统微处理器,负责数据采集运算和传动部分的控制,以PC机作为项目的编辑管理器。与传统的单片机或工控机为主导的半自动生化分析仪相比,在测量方法、数据采集与运算、温度、光强控制等方面,均由高速DSP来集中处理,具有硬件集成度高、数据处理速度快、价格便宜、可靠性高等优点,适用于在中小医院加以推广使用。

The semi-automated biochemistry analyzer based on digital signal processor （DSP） is presented. TMS320F2812 chip from TI is used as the systematic processor to take care of data acquisition, operation and control the transmission part ; and the personal computer is used as edit manager for the project. Comparing with traditional semi-automated biochemistry analyzers conducted by single chip computer and IPC, because all the measuring functions of the analyzer, e. g. , data acquisition and operation, control of temperature and light intensity are processed by high speed DSP, the integrated level of hardware is increased, and data processing is under high speed, and instrument features low cost and high reliability; thus it is easy to be promoted in medium or small hospitals.
