【正文】 示在 LCD1602 液晶屏上 ; 當(dāng) 測(cè)量到脈搏跳動(dòng)次數(shù)的結(jié)果,屏幕顯示的同時(shí) 超過 設(shè)定 范圍的 狀況 下 , 單片機(jī)會(huì)驅(qū)動(dòng) 內(nèi)置 蜂鳴器 發(fā)出 報(bào)警。 電子脈搏計(jì)由光電傳感器、 STC89C5四個(gè)按鍵、運(yùn)放、 LCD160蜂鳴器 等構(gòu)成,按鍵用來(lái)設(shè)置脈搏跳動(dòng)次數(shù)的上限和下限 。 第五章:總結(jié)在電子脈搏計(jì)設(shè)計(jì)的論文中得到的啟示和收獲。 第 三 章 :描述電子脈搏計(jì)的硬件設(shè)計(jì),按照各個(gè)模塊需要實(shí)現(xiàn)的功能,設(shè)計(jì)電路將幾個(gè)模塊連接起來(lái),最終實(shí)現(xiàn)總體的功能。 本論文的研究工作安排 第 一 章 : 簡(jiǎn)單介紹 了課題背景及電子脈搏計(jì)的 研究 現(xiàn)狀 。 需要 測(cè) 量 的兩種信號(hào)經(jīng)通道選擇 以 后 , 再 來(lái) 進(jìn)行顯示 。 多通道 的 數(shù)字脈搏測(cè)量?jī)x, 其 測(cè)量 的 部分 主要包括 兩個(gè)通道, 蜂鳴器 報(bào)警顯示 會(huì) 占用一個(gè)通道。 設(shè)計(jì)的電路選用 紅外 光電 傳感器 , 把脈搏跳動(dòng)轉(zhuǎn) 化為電信號(hào),放大 、 濾波。 電子脈搏計(jì)發(fā)展現(xiàn)狀 現(xiàn)今電子脈搏計(jì)的設(shè)計(jì)主要 包括以下 兩種,一種是多通道 的 數(shù)字脈搏測(cè)量?jī)x 的 設(shè)計(jì) ,另外 一種 則 是基于 EWB 的 電子脈搏測(cè)量?jī)x 的 設(shè)計(jì)。并且自動(dòng)監(jiān)測(cè) 也為自動(dòng)控制創(chuàng)造了先決條件,自動(dòng)監(jiān)測(cè)設(shè)備監(jiān)測(cè)到的真實(shí)情況反饋到中央處理器,中央處理器進(jìn)行進(jìn)一步判斷,才能實(shí)現(xiàn)自動(dòng)控制。電子脈搏計(jì) 的更新, 正是基于大規(guī)模 的 集成電路 以及 計(jì)算機(jī)技術(shù) 才 發(fā)展起來(lái)的,單片機(jī)的 存在 ,使 得很多電子設(shè)備,包括 電子脈搏計(jì)自動(dòng) 控制 和 監(jiān)測(cè)的實(shí)現(xiàn) 成為可能。 電子脈搏計(jì)可以 準(zhǔn)確 地對(duì)脈搏跳動(dòng) 的 情況進(jìn)行實(shí)時(shí) 地 監(jiān)測(cè),能夠反映 出脈搏的 均勻 狀況 ,監(jiān)測(cè) 瞬時(shí) 脈搏和 平均 脈搏。然而單片機(jī)這種嵌入式控制器也分為通用型和專用型兩種,通用型適合大批量生產(chǎn),在市場(chǎng)上也容易買到,但是專用型卻是需要特別設(shè)計(jì),不適合大批量、大范圍的應(yīng)用 [1]。大規(guī) 模集成電路的 不斷 發(fā)展,使得單片機(jī) 這項(xiàng)技術(shù) 得以問世 。以往普遍脈搏跳動(dòng)的情況,都是醫(yī)生或者病人的手放到手腕動(dòng)脈血管,通過手感覺到的壓力次數(shù)來(lái)測(cè)試脈搏跳動(dòng)的次數(shù),時(shí)間大約是一分鐘,這樣既不精準(zhǔn),也不能夠保證實(shí)時(shí)地、持續(xù)性地監(jiān)測(cè)病情。 關(guān)鍵詞: 電子脈搏計(jì); 51 單片機(jī);硬件設(shè)計(jì);軟件設(shè)計(jì) 山西 農(nóng)業(yè)大學(xué)信息學(xué)院畢業(yè)設(shè)計(jì) II Abstract Magical place of Traditional Chinese Medicine is inspection,auscultation and olfaction,inquiry and palpation,the palpation means that pulse beat diagnosis,the pulse wave is largely vibration which for the blood of artery flowing through the body according to periodicity pulse wave consist a large of dynamic information about the heart and the system of inside and outside circulation and the same time pulse measurement provides a physiological reference signal for blood flow measurement ,blood pressure measurement and some other physiological detection technology. However, the energy and fixed number of years for cultivate doctor of Traditional Chinese Medicine is very huge,the doctor of Western medicine using the device for measuring pulse beat frequency, bined with other medical equipment monitoring is a way, so the electronic pulsometer plays an important role in the progress of medicine. Design of electronic pulsometer is divided into two parts: software design and hardware design, the design of the content need consider function and demand of the design object,then division conduct according to the module of each different function, therefore the module of hardware in this paper is divided into main control module,signal acquisition module, display module, buzzer module, keyboard module. Pulse meter using infrared sensors to collect the pulse signal, after shaping and amplifying,enter the signal to the single chip microputer to corresponding control, which measured within the pulse beat frequency in a minute, convenient and fast. System main control chip use STC89C52, the pulse signal acquisition to display on the LCD1602. I in electronic pulse meter design, step by step in different functional modules of study, to the core of the scientific and technological achievements of the study before and now better ponents, pare, and finally to every part of the final choice together, form a plete excellent electronic pulse meter, so we can understand the specific ponent model and the function, not only in theory of textbooks. I am in the process of classification, parison and design, system review again the university to study a variety of professional knowledge, and to many disciplines together, flexible application. In the end, I start to make the electronic pulse meter, when their own design electronic pulse meter physical done finally, accurate 山西 農(nóng)業(yè)大學(xué)信息學(xué)院畢業(yè)設(shè)計(jì) III measured their pulse of The Times, a kind of happiness to let my heart excited, I know it will be a stepping stone in my life, let me confidence further.
