本科毕业设计(论文)题目：血小板聚集测试仪硬件设计院（系）：电子信息工程学院专业：电气工程及其自动化班级：指导教师：郑伟旗2010年6月血小板聚集测试仪硬件设计摘要血小板聚集测试仪是测量血小板聚集度的一个半自动仪器，它结合了计算机技术与光电测试技术完成对血小板聚集程度测试，具有人机界面良好，操作简便，测试精度高的特点，可同时对四路试剂进行测试，并将测试结果打印输出，亦可对待测试剂进行育温保护。本文依据聚集测试的基本原理，介绍了一种四路血小板聚集测试系统的设计。该系统选用PHILIP80C552单片机作为主控芯片，通过四路聚集测试电路，放大电路，温度采集电路，温度控制系统实现整个系统的采集，数据处理，显示，打印和监控。测试结果以数值形式在LCD液晶显示器上进行显示，从打印设备输出。关键词：PHILIP80C552单片机；聚集测试；温度控制；存储器；液晶显示。Platelet aggregation tester hardware designAbstract Platelet aggregation tester is a measure of the degree of platelet aggregation a semi-automatic instrument, it combines the computer technology and the test of platelet aggregation technology level, has the good human-machine interface testing, simple operation, high precision, but also the characteristics of four road test, and reagents test result, can treat print test agent (temperature protection. Based on the basic principle, testing gathered introduced a kind of four road platelet aggregation testing system is designed. The system selects PHILIP80C552 microcontroller as the main control chip, through the test circuit together, amplifying circuit, temperature sampling circuit, temperature control system of the whole system, data processing, display, print and monitoring. Test results with numerical form in LCD display, from the print on output device.Key words:PHILIP80C552 microcontroller,Gather test,Temperature control, Memory, LCD display.目录摘要......................................................................................................(I)Abstract...............................................................................................(Ⅱ)1 绪论..................................................................................................(1)1.1综述..............................................................................................................(1) 1.1.1课题简介..............................................................................................(1) 1.1.2国外研究情况.......................................
