摘　　要：介绍了一种以80C552单片机为控制核心,采用新型可编程通用单片机外围芯片PSD311、I2C芯片24C256、看门狗电路、DS1302、语音电路API8208、OCM320*240LCD和M-T102热敏打印机等器件构成的尿液分析仪。阐述了尿液分析仪的基本工作原理和封闭化、模块化的设计思路;采用软、硬件相互配合,实现对环境温度、环境光和尿色等因素的自动补偿,实现了数据的采集、处理、显示、打印、串行通信等功能;采用超大规模液晶显示器作为人机对话窗口;并带有实时时钟和语音提示功能。整个仪器操作方便,测量结果准确。This paper introduces an Urine Analyzer which uses 80C552 as its master controller. Other hardware embraces PSD311, serial E2PROM24C256,Watchdog,DS1302, high quality voice synthesizer API8208,OCM320＊240LCD and thermal printer M-T102,and so on. This paper also introduces the rationale of this instrument ,and module and closed mentality of designing; It adopts software and hardware to realize automatic compensation for environment temperature and luminance and urine color.The data gathering, processing, display, print and serial communication is realized; Super large-scale LCD is used as Interactive window; Real-time clock display and voice prompt; The result of measurement is quite right and the instrument is also easy to operate.
