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键入文字西安石油大学课 程 设 计电子工程学院自动化专业自动化1002班题 目 中压燃气锅炉控制系统设计学 生 指导老师 汤楠 二一三年六月1. 课程设计任务书12. 设计思想及内容23. 运行结果74. 元器件清单85. 个人小结96. 参考目录9 自动化仪表及过程控制 1。1课程设计任务书题 目 中压燃气锅炉控制系统设计-汽包控制学生姓名学号407专业班级自动化1002设计内容与要求本次课程设计的目的是熟悉过程控制系统的组态和调试，掌握自动化仪表与过程控制的基本应用,加深和巩固本课程及相关课程的知识，要求完成如下内容：1.熟悉油田中压燃气锅炉的工艺流程， 并对汽包液位-锅炉给水串级控制的工作过程进行分析。2。依据工艺流程和基本数据， 对所用仪表作出选型;3。对控制回路画出方框图，写出所选控制规律，及参数整定方法；4.了解组态软件的历史、发展及国内外现状，熟悉组态软件的应用,利用力控组态软件做出油田中压燃气锅炉监控系统的组态设计，并在报告中写出组态过程如：I/O端口分配、I/O点组态参数说明、控制回路组态说明等.最终要求做出工艺流程画面、趋势画面、报警画面，并利用软件提供的模拟对象，实现系统的自动控制。5完成课程设计报告。起止时间20 13 年 6 月 18 日 至 20 13 年 6 月 23 日指导教师签名年 月 日系(教研室）主任签名年 月 日学生签名年 月 日2。设计思想及内容2。1 设计思想 锅炉是工业生产过程中不可缺少的重要设备，锅炉的汽包水位是影响锅炉安全运 行的重要参数，水位过高，会破坏汽水分离装置的正常工作，严重时会导致蒸汽带水增多，增加在管壁上的结垢和影响蒸汽质量.水位过低,则会破坏水循环，引起水冷壁管的破裂，严重时会造成干锅，损坏汽包，所以其值过高过低都可能造成重大事故.故在设计中内、外贿赂中采用PID控制快速消除通道的给水扰动和蒸汽扰动,使系统达到稳定的状态。本题的设计基本工艺流程如下：温度约60的预热锅炉给水经锅炉盘管烧热后进入汽包，在汽包中,高温高压的水汽化,产生中压蒸汽(温度约150，压力1。5MPa），中压蒸汽经计量后由中压总管分送各用户。设计产汽量为 10 吨/小时，燃气为天然气，燃气压力为0.4MPa，温度约10。2。2 设计内容 一、开发系统的设计各窗口页面的设计本设计分为三个部分报警画面、工艺画面及趋势画面.工艺画面 按照题目中给的原理图来设计.在工具箱中点击“选择子图”按钮,可在其中找到模拟加热炉、汽包、水泵和阀门.再用工具箱中的立体管道将其按图连接,工艺图就构成了.趋势画面报警画面各画面的链接 在各画面中建立两个按钮分别表示除自身外另外两个画面。然后再在对象动画中点击窗口显示，建立链接。使各窗口可互相切换。二、动画的设计 在工艺画面中，对各对象都添加动画。是运行时，各部分变化明显。3.运行结果 在运行系统中检验设计结果.进入趋势画面，改动设定值、P和I，观察变化。 趋势画面未改变时将设定值改为50。000，P改为30。000，I，改为60。000后。工艺画面 未改变时 改变后报警页面未改变时改变后4.元器件清单序号器件名称数量备注1Tin371汽包24401中压锅炉3Pump21水泵4Vlve232阀门5立体导管5链接5。设计总结该设计主要完成了中压燃气锅炉汽包控制的部分，并未涉及安全控制,锅炉控制等等。通过收集各种汽包液位控制的资料，了解其制作过程,并通过各种比较完成了该设计.并通过学习，应用了力控软件，自觉收益颇丰。还好此次设计是老师手把手带着做的,不仅让我对力控这个软件有了些许认识，更是让我亲手完成了整个过程。之前的课程设计多是要自己完成，免不了要借鉴前人做过的报告，但是此次报告确是我一字一字完全靠自己做出来的。也学有很多不足之处,但是我相信有了这一次，下回会更熟练。通过此次设计，加深了我对汽包液位控制的理解，还有对于控制也有了进一步的思考。所以课程设计在这一方面是有实质性的好处的。仅仅有书本上的知识是不够的，以后进入社会，更多的需要实践能力和把自己所学的知识加以运用的能力。所以我感谢课程设计带给我的明晰,我会更加努力的。6. 参考目录 1. 施仁 刘文仁 郑辑光 王勇自动化仪表与过程控制（第五版)电子工业出版社2. 张益农,萧德云.

In perform duties, and carried out work of process in the, we to put people as a guide principles, and a test standard, efforts from masses most hope do of things do up, from masses most care of hot problem grabbed, from masses most not satisfaction of place modified up, not make nominal of formalism, not do grandstanding of cosmetic, to seeking of style, help masses share, is people benefit. (C) the investee people is not only an idea, it is a job requirement. Philosophy through to the people-oriented thought in the work of the Office, must be clear work objectives. Party Office in the city this year remains: Advanced civil strife, local brand. The County (City) Party Committee offices and units directly under the Office to hold high the banner of first to excellence, people-oriented requirements, strengthen the construction and management of the Office towards the work a higher level. Investee 1. political participation based on conspiracy to adhere to people-oriented, will be around to promote coordinationDevelopment events, great searchings. The 16 session of the partys scientific Outlook on development, is the new Central collective leadership to the development of connotation, development essentials, further deepen the essence of development and innovation, is our partys ruling idea a leap. At present, establishing and implementing the scientific concept of development has become the partys important work. As the Office of party Committee, working party should service center, initiative to claim leadership of the decision, the current focus is to focus on promoting comprehensive, coordinated and sustainable development with more suggestions, do more research, summarized the typical. One is drafted to raise the level of your presentation. Your presentation is the main Office of products, is the basic carrier staff service, is important to measure service levels. The quality of your presentation, mainly depends on how much we drafted a document recognized by the leadership, how many are listening to the people in favour of the report, how many paid dividends in the practical work. Improve presentation drafting level, requirements we accurate grasp led intent, General led care of work are to as understand, General led consider of problem are to in-depth thinking; requirements we highlight place features, put superior approach policy and local actual combined up, put presentation of theme thrust and masses of by thought by wants to combined up; requirements we seeks to streamlined clear, with simple of language expression deep of thought, with short of length hosted rich of connotation. Second, the survey results more. Investigation of the base, the road to success is something, is our for the Party Committees policy decision a good idea, an important part of a good staff.
