医院病人紧急呼叫系统设计

，通过和同组同学的相互交流才使我对本设计有了清晰地认识。另外在设计的过程同学们提出的好的建议使我意识到学习贵在交流，只有在交流中才能提升自己，才能丰富自己的知识;只有在交流中才能产生许多新的火花新的思想。设计的过程中让我更加深入的了解了数电知识，让我有一个能够综合运用数、模知识机会。让我的动手能力，逻辑思维能力的到了相应的锻炼。也让我知道了做任何事情都应该以严谨的态度对待，否则一个小小的错误就可能导致整个设计的失败。这个设计让我有了能够综合运用所学知识的机会;让我的动手能力，逻辑思维能力得到了相应的锻炼。也让我对学习有了新的理解。以前我一直认为学习就只是意味课本上的东西而已。而学到的知识也只是纸上谈兵，根本就没有实际的应用，因此对学习并不是很积极。而这次的课程设计完全改变了我的想法，让我知道了理论的存在是为了指导实践，没有了理论的指导就不会有实践的成功，理论和实践是不可分的整体。一切的产品的开发都要拥有一定的经济基础，产品的原料要尽可能的简单，价格尽可能的低廉，要大家都会用并且用得起。我们现在所学的一切都是为了将来能更好的为社会服务，同时让我了解到了本人所学专业与社会需要的联系。让我对工程与社会，经济，文化，环境等方面的联系有了更新的认识。 在完成之际，我要特别感谢我的指导老师胡宏平老师的热情关怀和悉心指导。在我撰写论文的过程中，胡宏平老师倾注了大量的心血和汗水，无论是在论文的选题、构思和资料的收集方面，还是在论文的研究方法以及成文定稿方面，我都得到了胡老师悉心细致的教诲和无私的帮助，特别是他广博的学识、深厚的学术素养、严谨的治学精神和一丝不苟的工作作风使我终生受益，在此表示真诚地感谢和深深的谢意。 在论文的写作过程中，也得到了许多同学的宝贵建议，同时还到许多在工作过程中许多同事的支持和帮助，在此一并致以诚挚的谢意。感谢所有关心、支持、帮助过我的良师益友。 致 谢 本课题在选题及研究过程中得到赵建平老师的悉心指导。赵老师曾多次询问论文进程，并为我指点迷津，帮助我开拓研究思路，精心点拨、热忱鼓励。赵老师一丝不苟的作风，严谨求实的态度，踏踏实实的精神，给我以终生受益无穷之道,在此对赵老师致以深深的感谢～ 参考文献 [1]康华光(电子技术基础模拟部分(第五版)[M](武汉华中科技大学:高等教育出版社，2005.7 [2] 康华光(电子技术基础数字部分(第五版)[M](武汉华中科技大学:高等教育出版社，2005.7 [3] 李东生.Protl 99SE电路设计技术入门与应用[M].合肥:电子工业出版社，2001.12 [4]吴慎山.电子线路设计与实践[M].北京:电子工业出版社 2005.9 [5]安真菊.电子技术课程设计[M].北京:机械工业出版社 2007.1 [6]徐敏.电子线路实习指导教程[M].北京:机械工业出版社 2005.8 [7]彭军.电子线路设计与制作[M].北京:科学出版社 2005.4 [8]肖玲妮.袁增责 Protel 99 SE 印刷电路板设计教程[M].北京:清华大学出版社 2003.7 [9]清源科技.Protel 99 SE 电路原理图与PCB设计及防真[M].北京:机械工业出版社 2007.1 [10]谢自美.电子线路设计?实验?测试[M].武汉:华中科技大学出版社 2005.9 [11]高平.电子线路设计基础[M].北京:化学工业出版社 2007.1 [12]李银华.电子线路设计指导[M].北京:北京航空航天大学出版社 2005.6 [13]臧春华.电子线路设计与应用[M].北京:高等教育出版社 2005.6 [14]葛汝明.电子线路实验与课程设计[M].济南:山东大学出版社 2006.3 [15]宋家友.张友汉 新编电子线路设计实用手册[M].福州:福建科学技术出版社 2007.5 [16]李洋.现代电子设计与创新[M].北京:中国电力出版社 2007.7 附录: 呼叫显示模块、优先显示模块、5秒呼叫模块的互相连接如下图: 相关设计软件: Protel99se是原Protel technology公司开发基于Windows环境的电路板设计软件。其强大的功能使电子线路的设计效率大为提高，已成为众多电子线路设计人员首选的计算机辅助设计软件。它是目前国内最流行的通用电子设计自动化(EDA)软件，它是将电路原理图设计，PCB板图设计，电路仿真和PLD设计等多个实用工具软件组合构成的EDA工作平台应用面广，是第一个将EDA设计成基于Windows环境的普及型产品。该软件功能强大，自动化和智能化程度高，人机界面好，易学易用，并且具有良好的实用性，开放性和数据交换性。现目前在我国不论在教学或者是在商业中只要是有关于电路设计和仿真多数情况都是使用Protel来完成。 附录:外文翻译 In Wang Zuoliang?s translation practices, he translated many poems, especially the poems written by Robert Burns. His translation of Burn?s “A Red, Red Rose” brought him fame as a verse translator. At the same time, he published about ten papers on the translation of poems. Some argue that poems cannot be translated. Frost stresses that poetry might get lost in translation. According to Wang, verse translation is possible and necessary, for “The poet-translator brings over some exciting work from another culture and in doing so is also writing his own best work, thereby adding something to his culture. In this transmission and exchange, a richer, more colorful world emerges. ”(Wang, 1991:112). Then how can we translate poems? According to Wang?s understanding, the translation of poems is related to three aspects: A poem?s meaning, poetic art and language. (1)A poem?s meaning “Socio-cultural differences are formidable enough, but the matter is made much more complex when one realizes that meaning does not consist in the meaning of words only, but also in syntactical structures, speech rhythms, levels of style.” (Wang, 1991:93). (2)Poetic art According to Wang, “Bly?s point about the „marvelous translation? being made possible in the United States only after Whitman, Pound and Williams Carlos Williams composed poetry in speech rhythms shows what may be gained when there is a genuine revolution in poetic art.” (Wang, 1991:93). (3)Language “Sometimes language stays static and sometimes language stays active. When language is active, it is beneficial to translation” “This would require this kind of intimate understanding, on the part of the translator, of its genius, its idiosyncrasies, its past and present, what it can do and what it choose not to do.” (Wang, 1991:94). Wang expresses the difficulties of verse translation. Frost?s comment is sufficient to prove the difficulty a translator has to grapple with. Maybe among literary translations, the translation of poems is the most difficult thing. Poems are the crystallization of wisdom. The difficulties of poetic comprehension lie not only in lines, but also in structure, such as cadence, rhyme, metre, rhythm, all these conveying information. One point merits our attention. Wang not only talks about the times? poetic art, but also the impact language?s activity has produced on translation. In times when the language is active, translation is prospering. The reform of poetic art has improved the translation quality of poems. For example, around May Fourth Movement, Baihua replaced classical style of writing, so the translation achieved earth-shaking success. The relation between the state of language and translation is so
