宽量程低功耗便携式血糖仪设计

摘要

介绍了一种宽量程低功耗的便携式血糖仪设计。本设计基于酶电转换检测原理，利用TI公司MSP430FG439低功耗单片机的OA、ADC、温度检测及FLASH等内部模块，通过对微电流宽量程放大，高精度数模转换和环境温度校正，能精准的测试出血糖浓度值，并具有检测值显示存储和历史平均值的查询功能。%A design on wide-range and low-power consumption portable blood glucose meter is introduced . The design based on glucose oxidase electrode detection principle takes the MSP430FG439 low-power microcontrol er from TI company,which we use the internal module of OA ,ADC ,temperature testing and flash memory .The presented blood glucose meter through magnifying the measuring range of microcurrent and high precision ADC and puting right ambient temperature to make the blood sugar concentration be tested by the bood glucose meter accurately.In addition,the presented blood glucose meter can display ang store the detection data and historical data query function.
