d look like a little ball. Every time we see them swim away and we feel their happiness of returning home and this also make us cherish life. Maybe some will consider these behavior as something childish. Well, that is fine with us. We love doing these together and feel happy that is what it is all about. My dear hubby is a kind hearted man and he love animals just as I do. I am lucky to have someone who can be both my intimated soul mate and my forever friend. 。s Day on February 14, characterized by bouquets of roses, chocolates and romantic candlelight dinners, than they do about their homegrown day for lovers. Even Qixi is nowadays referred to as the Chinese Valentine39。s largest virgin forest, and known for its spring and ecological environment, Arxan is marveled at by many tourists as the purest land on earth. You cannot miss out the Autumn of Arxan. It is definitely the best with brightlycolored scenery full of emotions. Autumn in the northern part of the country es earlier than the South. A September rain followed by the footprints of Autumn brings more colors to the once emerald green mountain and blooming grassland. Shutterbugs flock to see for themselves the marvel of splendid colors around the mountains and waters, many of whom have travel a long distance and even camp here only to capture a moment of the nature wonder. The silver birch turns golden, while the larch is still proudly green. You will find yourself drowned in the intoxicating red of the wild fruits as well as the glamour of flowers in full blown. And your heart will be lingering on the woods as it39。============================================ 14 STOP: CLR CLR CLR CLR MOV 6CH, 5 MOV 6DH, 5 MOV 6EH, 5 MOV 6FH, 5 JMP MAIN 。困難主要出現(xiàn)在后期,與軟件合成后調(diào)試時, 發(fā)現(xiàn)傳感器信號輸出方 10 面無變 北京:國防工業(yè)出版社, 1998. 11 附錄 1:附圖 原理圖 注明: 四位數(shù)碼管分別對應(yīng)四張床位 原理圖左邊四個按鈕用來模擬四個液位傳感器 12 電路 PCB 板圖 13 軟件代碼 ORG 0000H AJMP START ORG 000BH 。 8 圖 報警電路 4 軟件設(shè)計 軟件設(shè)計主要分為初始化程序、存儲單元和中斷設(shè)置初始化,主程序(內(nèi)嵌報警程序)、報警中斷子程序、中斷服務(wù)子程序(顯示程序)、延遲子程序。我們的主要思想是:當 1 號床位的點滴低于“設(shè)定”液位,由紅外液位傳感器輸出的低電平,送入單片機的 口(四張床位的檢測信號分別對應(yīng)、 、 、 ),然后由單片機的內(nèi)部加以處理,由 P2 口、 P1口 的高三位、 74LS138 譯碼器等作用,在 LED 上顯示出對應(yīng)的床位。 74HC138 是一個 38 譯碼器。掉電方式保存 RAM 中的內(nèi)容,但振蕩器停止工作并禁止其它所有部件工作直到下一個硬件復(fù)位??删幊檀?UART 通道 128X8 字節(jié)內(nèi)部 RAM 8k 字節(jié)可重擦寫 Flash 閃速存儲器 當?shù)陀诰湟何粫r,光敏二極管導(dǎo)通, 3 端則輸入低電平, 5 端隨之也取反,然后送入單片機處理,已發(fā)出報警。 其中最核心部分的部分是信息處理模塊和檢測模塊。而且應(yīng)用對象為點滴瓶,采用方案一,安裝不方便,而且超聲波傳感器在這種應(yīng)用下存在盲區(qū) ,且對不同的大小的點滴瓶都要重新設(shè)定參數(shù)。當由控制輸入后,表示醫(yī)護人員已經(jīng)去對事件進行處理。 超 聲 波 傳 感 器 A / D 轉(zhuǎn) 換報 警 裝 置單片機控制系統(tǒng) L E D 顯 示鍵 盤 輸 入L E D 顯 示鍵 盤 輸 入 圖 液位監(jiān)測報警系統(tǒng)方案一框圖 方案二 : 如圖 所示系統(tǒng)結(jié)構(gòu)框圖, 本 方案仍 以微型單片機為控制核心,由檢測模塊、信息處理模塊 、 LED 信息顯示模塊、控制輸入模塊 和報警 模塊 五 大部分組成。 方案一 :如圖 所示系統(tǒng)上電工作后,用戶首先通過鍵盤設(shè)定溫度的初值,單片機系統(tǒng)將用戶設(shè)置的“警戒值”保存地址空間中。該系統(tǒng)可讓醫(yī)護人員在控制室 監(jiān)控 不同受液者的輸液狀況,也可以直接到輸液室直接改變輸液狀態(tài),了解病人的輸液進程,及時通知處理將快完成的輸液。運來越多的地方需要用到一些高科技設(shè)備來為人們服務(wù)。課程設(shè)計 基于單片機的醫(yī)用點滴余液液位監(jiān)測報警系統(tǒng) I 課程設(shè)計說明書 目 錄 1 前言 ....................................................... 1 2 總體方案設(shè)計 ................................................ 2 方案論證 ............................................................................................................... 2 ................................................................................................................ 3 3 單元模塊設(shè)計 ................................................. 4 監(jiān)測模塊 ............................................................................................................... 4 ............................................................................................................ 4 LED信息顯示模塊 .................................................................................................. 6 控制輸入模塊 .........................................................................
