| 毕业论文 基于GPRS的制冷设备远程监控系统的设计与实现 共35页，24328字 摘要 在冶金工业的生产过程中，大量使用制冷设备，作为生产的重要环节。保证 这些大型制冷设备的安全，可靠，稳定运行对冶金生产具有重要的意义。攀企瑞 通制冷公司肩负着攀钢集团关键区域和关键设备的制冷任务。本课题来源于攀企 瑞通制冷公司的自动化改造项目。 根据攀企瑞通制冷公司对制冷系统信息远传的改造要求。针对目前攀钢大型 制冷机组分散的特点，基于通用分组无线业务(GPRS)的基本理论，充分利用现代 通信的GPRS技术，参考国内现有设备远程监控系统设计思想，设计了本论文的 远程监控系统。本文介绍了系统总体设计思想与实现功能，并在此基础上对系统 结构及实现方案进行了深入分析与研究，提出了GPRS网络与Internet网络结合、 采用动态域名解析方法的通信实现方案。 在初步设计的基础上，本人进行了一些基础性的试验，根据试验的结果对系 统进行了不断的修改和完善，并最终使制冷设备远程监控系统得以实现。 本系统现已试运行,系统功能丰富，便于操作，成本低，安装与维护方便，且 便于以后的开发与扩展。 关键词：制冷设备，GPRS，系统结构，远程监控 II ABSTRACT Lots of the refrigeration equipment is using in the production process of the metallurgy industry as important tache.The refrigeration equipment safety,steady and credible run is important role for the metallurgy production.The refrigerated tasks of the key area and equipment in Pan Gang group are charged with Ritong refrigeration company.The thesis origin from the automatic reform item of the company. Based the reform request on the refrigeration system information long-distance transfer,design the remote monitoring system,aimed at the dispersive trait of the large refrigeration set in Pan Gang present.Based on the basic theories of GPRS,making good use of modern technology,referred the existing design idea of the equipment remote monitoring system in our country.In this paper,design idea and functions of the full system are introduced,based on which,the system structure and the scheme realization are analyzed and studied deeply.Joining GPRS and Internet network together,the communication method is put forward with the dynamical resolve of domain name. On the primary design,I have carried through some basic experiment.By the result of the experiment,I have adopted and perfected the system.Finally the refrigeration equipment remote monitoring system has realized. The system now has put into operation.It has abundant functions and has many merits,such as convenient operation,low cost,convenient to setup and maintenance,easy to development and extend. Keywords:Refrigeration equipment,GPRS,System structure,Remote monitoring III 目录 摘要........................................................................................................................I ABSTRACT............................................................................................................II 第一章引言.............................................................................................................1 1.1课题背景..........................................................................................................1 1.2远程监控现状及发展趋势..............................................................................1 1.3课题来源..........................................................................................................3 1.4课题研究的目的和意义..................................................................................4 1.5本文的主要工作..............................................................................................5 第二章GPRS技术简介.........................................................................................7 2.1 GPRS的定义...................................................................................................7 2.2 GPRS的工作原理...........................................................................................7 2.3 GPRS优势.....................................................................................................15 2.4应用GPRS网络的不足...............................................................................16 第三章远程监控系统设计...................................................................................18 3.1 GPRS无线数据传输系统的设计原理.........................................................18 3.2系统的总体结构............................................................................................19 3.3系统的设计目标............................................................................................20 IV 3.4组网方案的选择............................................................................................21 3.5最终方案的选择............................................................................................23 3.6利用GPRS来实现监控系统的数据传输...................................................24 3.7系统工作流程...............................................................................................24 第四章制冷设备远程监控的设计.......................................................................26 4.1设计概要.......................................................................................................26 4.2系统功能........................................................................................................26 4.3系统技术指标................................................................................................27 4.4系统设计.......................................................................................................27 4.5远程监控中心的功能设计............................................................................31 第五章制冷设备远程监控的实现.......................................................................33 5.1现状调查........................................................................................................33 5.2试验方案........................................................................................................33 5.3试验方案出现的问题及解决方案................................................................34 5.4远程监视功能的实现：................................................................................36 5.5测试和验收....................................................................................................40 5.6技术总结........................................................................................................41 第六章总结与展望...............................................................................................43 6.1研究总结.......................................................................................................43 V 6.2研究展望.......................................................................................................43 致谢.....................................................................................................................45 参考文献.................................................................................................................46 个人简历及学术论文发表.....................................................................................48 一，个人简历......................................................................................................48 二，论文发表......................................................................................................48 |
