is one of the practical form of values. The so-called values refers to the objective things are of no value and the value of fundamental perspective. Different values, peoples behaviour, attitudes, ways are different. People-oriented focus on human value and reality, we need the broadest masses as values. Adhere to people-oriented values, is to make the economy more development, improve democracy, cultural prosperity, and live a happier; is deeply concerned that human development and human values, development of social and human development of rational unified, insisted in the material civilization, political civilization and spiritual civilization in the overall advancement of Socialist civilization to a higher level. Also want to see that persons value is not only meet your needs, also is to meet the needs of others and the community. Adhere to people-oriented, to strongly advocate every community member, serve others, beneficial to the community of people. The so-called Outlook, attitude is on the record, including who, how to create a record of achievements, how to evaluate performance, and so on. What values, what kind of Outlook. Adhere to people-oriented Outlook, is on the premise of respecting the interests and power of people, creating a popular, warm hearts, steady heart performance, creating serve for one officer, the benefit of achievements, and overall construction of well-off society and promoting the all-round development of peoples performance. Achievement evaluation in both economic accomplishments, take another look at the effectiveness of social progress; changes in both urban and rural change; both hard environment to strengthen and take another look at the soft environment improvement momentum of development at present, depending on the potential for sustainable development. Leave people to talk about values are worthless and leave people to talk about Outlook is not what the performance. 4. people responded to the starting point of the question, and replied to questions point. Man is the sum of social relationships. We cannot leave the chichuanyongdu, housing, tourism and entertainment, entertaining, and even certain political, economic, cultural and social environment, and so on. Due to human needs, all walks of life will come into being. People create for their survival, and continue enjoying the results of the construction. Colorful in the transformation of the people of the world, community vitality in the creation of man. Therefore, any work we do, the starting point is human, what are people. Us speed up development, the core of which is to meet the needs of people, including survival needs, emotional needs and self-actualization needs. It should be noted that people are not machines, not the slave of an object, not to be controlled. People have their own personality, has its own personality, has its own dignity. Person in need of care, you need to understand, need to meet. It is said that in the agricultural society, people plant; in industrial society, man is an animal; the information society, return鍵入文字西安石油大學(xué)課 程 設(shè) 計電子工程學(xué)院自動化專業(yè)自動化1002班題 目 中壓燃?xì)忮仩t控制系統(tǒng)設(shè)計學(xué) 生 指導(dǎo)老師 湯楠 二一三年六月1. 課程設(shè)計任務(wù)書12. 設(shè)計思想及內(nèi)容23. 運行結(jié)果74. 元器件清單85. 個人小結(jié)96. 參考目錄9 自動化儀表及過程控制 1.1課程設(shè)計任務(wù)書題 目 中壓燃?xì)忮仩t控制系統(tǒng)設(shè)計-汽包控制學(xué)生姓名學(xué)號407專業(yè)班級自動化1002設(shè)計內(nèi)容與要求本次課程設(shè)計的目的是熟悉過程控制系統(tǒng)的組態(tài)和調(diào)試，掌握自動化儀表與過程控制的基本應(yīng)用，加深和鞏固本課程及相關(guān)課程的知識，要求完成如下內(nèi)容:1.熟悉油田中壓燃?xì)忮仩t的工藝流程, 并對汽包液位鍋爐給水串級控制的工作過程進(jìn)行分析。2.依據(jù)工藝流程和基本數(shù)據(jù), 對所用儀表作出選型；3.對控制回路畫出方框圖，寫出所選控制規(guī)律，及參數(shù)整定方法；4.了解組態(tài)軟件的歷史、發(fā)展及國內(nèi)外現(xiàn)狀，熟悉組態(tài)軟件的應(yīng)用，利用力控組態(tài)軟件做出油田中壓燃?xì)忮仩t監(jiān)控系統(tǒng)的組態(tài)設(shè)計，并在報告中寫出組態(tài)過程如：I/O端口分配、I/O點組態(tài)參數(shù)說明、控制回路組態(tài)說明等。最終要求做出工藝流程畫面、趨勢畫面、報警畫面，并利用軟件提供的模擬對象，實現(xiàn)系統(tǒng)的自動控制。5完成課程設(shè)計報告。起止時間20 13 年 6 月 18 日 至 20 13 年 6 月 23 日指導(dǎo)教師簽名年 月 日系（教研室）主任簽名年 月 日學(xué)生簽名年 月 日2.設(shè)計思想及內(nèi)容2.1 設(shè)計思想 鍋爐是工業(yè)生產(chǎn)過程中不可缺少的重要設(shè)備，鍋爐的汽包水位是影響鍋爐安全運 行的重要參數(shù)，水位過高，會破壞汽水分離裝置的正常工作，嚴(yán)重時會導(dǎo)致蒸汽帶水增多，增加在管壁上的結(jié)垢和影響蒸汽質(zhì)量。水位過低，則會破壞水循環(huán)，引起水冷壁管的破裂，嚴(yán)重時會造成干鍋，損壞汽包，所以其值過高過低都可能造成重大事故。故在設(shè)計中內(nèi)、外賄賂中采用PID控制快速消除通道的給水?dāng)_動和蒸汽擾動，使系統(tǒng)達(dá)到穩(wěn)定的狀態(tài)。本題的設(shè)計基本工藝流程如下：溫度約60的預(yù)熱鍋爐給水經(jīng)鍋爐盤管燒熱后進(jìn)入汽包，在汽包中，高溫高壓的水汽化，產(chǎn)生中壓蒸汽(溫度約150，壓力1.5MPa)，中壓蒸汽經(jīng)計量后由中壓總管分送各用戶。設(shè)計產(chǎn)汽量為 10 噸/小時，燃?xì)鉃樘烊粴?，燃?xì)鈮毫?.4MPa，溫度約10。2.2 設(shè)計內(nèi)容 一、開發(fā)系統(tǒng)的設(shè)計各窗口頁面的設(shè)計本設(shè)計分為三個部分報警畫面、工藝畫面及趨勢畫面。工藝畫面 按照題目中給的原理圖來設(shè)計。在工具箱中點擊“選擇子圖”按鈕，可在其中找到模擬加熱爐、汽包、水泵和閥門。再用工具箱中的立體管道將其按圖連接，工藝圖就構(gòu)成了。趨勢畫面報警畫面各畫面的鏈接 在各畫面中建立兩個按鈕分別表示除自身外另外兩個畫面。然后再在對象動畫中點擊窗口顯示，建立鏈接。使各窗口可互相切換。二、動畫的設(shè)計 在工藝畫面中，對各對象都添加動畫。是運行時，各部分變化明顯。3.運行結(jié)果 在運行系統(tǒng)中檢驗設(shè)計結(jié)果。進(jìn)入趨勢畫面，改動設(shè)定值、P和I，觀察變化。 趨勢畫面未改變時將設(shè)定值改為50.000，P改為30.000，I，改為60.000后。工藝畫面 未改變時 改變后報警頁面未改變時改變后4.元器件清單序號器件名稱數(shù)量備注1Tin371汽包24401中壓鍋爐3Pump21水泵4Vlve232閥門5立體導(dǎo)管5鏈接5.設(shè)計總結(jié)該設(shè)計主要完成了中壓燃?xì)忮仩t汽包控制的部分，并未涉及安全控制，鍋爐控制等等。通過收集各種汽包液位控制的資料，了解其制作過程，并通過各種比較完成了該設(shè)計。并通過學(xué)習(xí)，應(yīng)用了力控軟件，自覺收益頗豐。還好此次設(shè)計是老師手把手帶著做的，不僅讓我對力控這個軟件有了些許認(rèn)識，更是讓我親手完成了整個過程。之前的課程設(shè)計多是要自己完成，免不了要借鑒前人做過的報告，但是此次報告確是我一字一字完全靠自己做出來的。也學(xué)有很多不足之處，但是我相信有了這一次，下回會更熟練。通過此次設(shè)計，加深了我對汽包液位控制的理解，還有對于控制也有了進(jìn)一步的思考。所以課程設(shè)計在這一方面是有實質(zhì)性的好處的。僅僅有書本上的知識是不夠的，以后進(jìn)入社會，更多的需要實踐能力和把自己所學(xué)的知識加以運用的能力。所以我感謝課程設(shè)計帶給我的明晰，我會更加努力的。6. 參考目錄 1. 施仁 劉文仁 鄭輯光 王勇自動化儀表與過程控制（第五版）電子工業(yè)出版社2. 張益農(nóng)，蕭德云.
