【正文】 ? 本科畢業(yè)論文 基于 AT89S51 單片機(jī)實(shí)現(xiàn)病房無線呼叫系統(tǒng) 設(shè)計(jì) 學(xué) 院： 計(jì)算機(jī)與信息工程學(xué)院 專 業(yè)： 計(jì)算機(jī)科學(xué)與技術(shù) 學(xué) 號： 091011668 姓 名： 指導(dǎo)教師： 職 稱： 副教授 論文提交日期：二 О一三 年六月 摘 要 病房呼叫系統(tǒng)主要是將病人的請求快速傳送給值班醫(yī)生或護(hù)士 , 用于協(xié)助醫(yī)院病員在病床上方便地呼叫醫(yī)務(wù)人員。該系統(tǒng)不僅是傳送臨床信息的重要手段 ,它也是提高醫(yī)院和病室護(hù)理水平的必備設(shè)備之一。 呼叫系統(tǒng)要求及時(shí)、 準(zhǔn)確、可靠、簡便可行。當(dāng)呼叫源有呼叫信號時(shí) ,在系統(tǒng)上有相應(yīng)的聲、光呼叫信號指示 ,并能顯示出呼叫號碼。本系統(tǒng)主要由 AT89S51單片機(jī)為主接器件設(shè)計(jì)的，介紹了電路設(shè)計(jì)及軟件實(shí)現(xiàn)方法，并給出了系統(tǒng)框圖，硬件電路及部分程序設(shè)計(jì)，該呼叫系統(tǒng)使用了高集成度射頻無線收發(fā)芯片進(jìn)行傳輸，不僅僅避免了傳統(tǒng)的有線尋呼系統(tǒng)布線復(fù)雜的問題，而且使整個(gè)電路簡捷、性能穩(wěn)定。 關(guān)鍵詞： AT89S51 無線 呼叫系統(tǒng) Abstract Ward calling system is an important means to transfer the clinical information。 patient39。s request can be quickly transmitted to doctor or nurse on duty. It?s mainly used to help patients call medical person conveniently, which is the necessary equipment of improving hospital ward nursing level. Calling system needs have the Characteristic of timely, accurate, reliable, simple and feasible. When the calling source has the calling signal, the system has the corresponding sound, indicating light call signal and it can demonstrates the call number. This system mainly consists of AT89S51 singlechip microputer as the core design, introduces the implement method of circuit design and software, and gives the system block diagram, hardware circuit and program design, the system uses a high degree of integration of RF transceiver chip franchise for transmission, not only it avoids the traditional wired paging system wiring plexity problems, but also the whole circuit is simple ,stable and performance.
