【正文】 Festival. In this day, girls will throw a sewing needle into a bowl full of water on the night of Qixi as a test of embroidery skills. If the needle floats on top of the water instead of sinking, it proves the girl is a skilled embroiders. Single women also pray for finding a good husband in the future. And the newly married women pray to bee pregnant quickly. Tradition transformed The love story of Niulang and Zhinu, and the Qixi Festival have been handed down for generations. Yet these ancient traditions and customs are slowly dying out. Many modern Chinese, particularly youngsters, seem to know more about St Valentine39。============================================ HERE: JNB , NEXT CPL JB , STOP CPL NEXT: SJMP MAIN 。其報警電路如圖 。而四位數(shù)碼管的位則通過 74HC138 譯碼器來選通。 8 個中斷源 與 Mcs 一 51 產(chǎn)品指令系統(tǒng)和引腳完全兼容 4 3 單元模塊設(shè)計 本課程設(shè)計主要 由 監(jiān)測 模塊、信息處理模塊 （單片機模塊）、 LED 信息顯示模塊、控制輸入模塊 和 報警 模塊 五 大部分組成。當(dāng)液位低于警戒液位時，傳感器將輸出一低電平，送入 口（一張床位對應(yīng)一個口，本設(shè)計只取一張床位模擬），然后由單片機內(nèi)部的程序，對信息進行處理，將病床號顯示到 LED 上 ，同時報警啟動，提醒醫(yī)護人員。 方案論證 設(shè)計中采用了兩個方案，具體的方案見方案一和方案二。 附錄 1：附圖 ................................................. 11 原理圖 ................................................... 11 電路 PCB 板圖 ............................................. 12 軟件代碼 ................................................. 13 附錄 2：相關(guān)設(shè)計軟件 .......................................... 15 1 1 前 言 隨著社會的發(fā)展，隨著科技的進步。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)。 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。當(dāng)由控制輸入后，表示醫(yī)護人員已經(jīng)去對事件進行處理。 其中最核心部分的部分是信息處理模塊和檢測模塊。 8k 字節(jié)可重擦寫 Flash 閃速存儲器 可編程串行 UART 通道 74HC138 是一個 38 譯碼器。 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。============================================ 14 STOP: CLR CLR CLR CLR MOV 6CH, 5 MOV 6DH, 5 MOV 6EH, 5 MOV 6FH, 5 JMP MAIN 。s Day on February 14, characterized by bouquets of roses, chocolates and romantic candlelight dinners, than they do about their homegrown day for lovers.

The magic shoes whisked Niulang, who carried his two children in baskets strung from a shoulder pole, off on a chase after the empress. The pursuit enraged the empress, who took her hairpin and slashed it across the sky creating the Milky Way which separated husband from wife. But all was not lost as magpies, moved by their love and devotion, formed a bridge across the Milky Way to reunite the family. Even the Jade Emperor was touched, and allowed Niulang and Zhinu to meet once a year on the seventh night of the seventh month. This is how Qixi came to be. The festival can be traced back to the Han Dynasty (206 BCAD 220). Traditionally, people would look up at the sky and find a bright star in the constellation Aquila as well as the star Vega, which are identified as Niulang and Zhinu. The two stars shine on opposite sides of the Milky Way. Customs In bygone days, Qixi was not only a special day for lovers, but also for girls. It is also known as the Begging for Skills Festival or Daughters39。============================================ MAIN: JB , BED2 SETB MOV 6CH, 1 BED2: JB , BED3 SETB MOV 6DH, 2 BED3: JB , BED4 SETB MOV 6EH, 3 BED4: JB , HERE SETB MOV 6FH, 4 。如果按下 口外接的按鈕，則報警停止，顯示也熄滅，表示已有醫(yī)護人員對信息進行處理。數(shù)碼管的 A、 B、 C、 D、E、 F、 G 和 DP 分別與單片機的 —— 相連。 3 個 16 位定時／計數(shù)器 5 圖 AT89C52 引腳 AT89C52 主要性能參數(shù) 因此，從設(shè)計和經(jīng)濟的角度講，我們組采用了方案二。 單片機啟動 ，開始監(jiān)測工作。首先通過液位傳感器檢測信號，然后將檢測到的信號送給單片機進行處理，通過數(shù)碼管和報警裝置，將床位信息顯示在監(jiān)控室，然后由護理人員對具體情況進行處理。 8 參考文獻 ......................................錯誤 !未定義書簽。 目前醫(yī)院普遍使用的是人工監(jiān)控點滴輸液裝置器，將液體容器掛在一定高度，利用勢差將液體輸入病人體內(nèi)，用軟管夾對軟管夾緊和放松控制滴速，藥物的有無將威脅病人的生命安全，為此 醫(yī)護人員 要不定時的觀察藥物的情況，本設(shè)計 根據(jù)需要設(shè)定液位控制高度，同時具備報警、高度顯示等功能，使用了紅外對射 傳感器，使其具有與液面
