摘要
针对家用健康检查监测设备小型化、快速化、易用性的需求,本文分析了传统的各种不同类型的干化学尿液分析仪的优点和不足,提出了一种基于CCD、LED和大芯径光纤等构成的微小型快速尿液分析检测系统。采用了ARM7和μC/OS-II嵌入式系统的方案,构建了以LPC2148微处理器为核心的硬件平台,采用LCD触摸屏模块来进行显示和控制,使仪器具有了友好的人机交互界面,满足了家庭用户的要求。设计了USB及无线传输模块,可连接至个人计算机,使用上位机软件进行数据的处理、保存及打印。理论分析和实验结果证明,该设计明显提高了测量速度和精度。
Based on the requirement with home health instruments in terms of miniaturization,fast testing and easy using,various traditional urine analyzers were analyzed.A miniature rapid urinalysis system based on CCD,LED and large-core optical fiber was proposed.ARM7 and μC/OS-II embedded system were adopted into the project which formed a hardware platform with the LPC2148 MPU as its core.LCD touch-screen module was used to display and control which made the man-machine interface friendly and satisfy the requireme...
