摘要：糖尿病作為威脅人類健康的四大疾病之一，己成為世界范圍內(nèi)難以治愈的流行疾病。中國(guó)目前已有近上億人患有糖尿病，而且該數(shù)據(jù)還在持續(xù)增長(zhǎng)。目前有效治療方法是頻繁檢測(cè)血糖值，定量注射胰島素，以維持患者血糖水平正常。為了人們能夠隨時(shí)掌握自己的血糖情況，本文設(shè)計(jì)了一種基于醫(yī)療物聯(lián)網(wǎng)的智能血糖儀。
系統(tǒng)以C8051F321單片機(jī)為核心，采用酶電極試紙作為傳感器來(lái)檢測(cè)血糖濃度。本文從設(shè)計(jì)方案、工作原理、設(shè)計(jì)目標(biāo)、硬件選型以及軟件流程等方面對(duì)系統(tǒng)進(jìn)行詳細(xì)描述。著重介紹硬件電路設(shè)計(jì)和軟件程序設(shè)計(jì)。硬件模塊主要根據(jù)功能需要進(jìn)行設(shè)計(jì)，包括基于C8051F321控制模塊、弱電流信號(hào)檢測(cè)模塊、數(shù)據(jù)存儲(chǔ)模塊、LCD顯示模塊、電源控制和串口通信模塊等電路設(shè)計(jì)。軟件設(shè)計(jì)主要包括參數(shù)修改、數(shù)據(jù)處理、短信發(fā)送和LCD顯示等程序設(shè)計(jì)。
結(jié)果表明該系統(tǒng)具有微創(chuàng)傷、適合家用、方便攜帶、操作簡(jiǎn)單、功耗低和測(cè)量快速準(zhǔn)確等優(yōu)點(diǎn)?；具_(dá)到了設(shè)計(jì)要求。

Based on the Medical Internet of Things Intelligence Glucose Meter Design
Abstract： Diabetes, one of the four diseases , has become difficult to cure disease worldwide as a threat to human health. China now has nearly hundreds of millions of people with diabetes, and the data continues to grow. The effective treatment method is frequent testing blood sugar levels, quantitative insulin injections, in order to maintain patient blood glucose levels to normal. In order to people to keep track of their blood sugar, the paper designed a kind of intelligent glucose meter based on medical Internet of things.
System with C8051F321 single-chip microcomputer as the core, using enzyme electrode strip as sensors to detect blood sugar levels. In this paper, from the design scheme, working principle, design goals of system, hardware selection and software process are described in details. Introduce the hardware circuit design and software programming. Hardware module is mainly designed to meet the need of function, including based on C8051F321 control module, the weak current signal detection module, data storage module, LCD display module, power control and serial interface communication module circuit design. Software design mainly includes the parameter modification, data processing, such as text messaging and LCD display program design.
The results show that the system has a micro trauma, suitable for home, convenient to carry, simple operation, low power consumption and the advantages of fast accurate measurement. Basic meet the design requirements.
