摘要
针对目前国内市场销售的医疗免疫检验设备主要是来自于国外进口、价格十分昂贵等现状,自主研发了一套全自动荧光分析仪系统,详细介绍了其FPGA/DSP运动控制+PC+STM32嵌入式微处理单元一体化的硬件结构设计、基于C#多线程的软件系统、双机制通信设计及其实现;通过精简硬件结构、合理硬件选型以及采用面向对象技术开发控制系统软件,控制系统精度和速度得到显著提高。最后进行了整机测试验证,说明该控制系统在功能、性能和成本上满足了全自动荧光分析仪的需求。
In view of the fact that medical inspection equipment sold in the domestic market is mainly imported from abroad and very expensive, we developed a full-automatic fluorescence analyzer in our center, presented in this pa- per. The present paper introduces the hardware architecture design of FPGA/DSP motion controlling card＋PC＋ STM32 embedded micro processing unit, software system based on C ~ multi thread, design and implementation of double unit communication in detail. By simplifying the hardware structure, selecting hardware legitimately and a- dopting control system software to object-oriented technology, we have improved the precision and velocity of the control system significantly. Finally, the performance test showed that the control system could meet the needs of automated fluorescence analyzer on the functionality, performance and cost.
