【摘要】：为了对氧化铝烧结工序中的异常情况进行监测,我们通过对氧化铝冷却机的熟料窑中铝成品熟料与滚筒窑撞击的声音数据进行现场采集,将采集到的声音数据文件保存在终端设备ARM开发板上,并建立一个小型局域网,通过局域网络将保存在终端设备ARM开发板上的声音数据发送给后台工作站。工作站对接收到的声音文件进行滤波、谱分析等后续处理,以此来对烧结工序中成品铝的异常状态进行判断,从而为工作人员及时排除异常情况提供参考依据。本文是基于32位三星公司最新ARM11微处理器S3C6410的一款开发平台,结合其支持的WinCE6.0开发环境,提出了工业现场声音信号采集、传输、分析及处理的技术。利用嵌入式技术、网络传输技术和数据处理技术的优势,解决了工业现场数据采集、传输困难,数据分析不准确的问题。氧化铝烧结工艺现场,由于环境因素复杂,窑口高温、噪音伴随多粉尘,这都给现场声音的采集、传输及终端设备的维护带来困难。本文中采用的采集、分析方法,有效避免了工业现场中的诸多问题,提高了后台工作站的数据处理能力,加强了结果分析的准确性。本文主要做了以下一些工作,以完成对现场声音数据的采集、分析及结果展示的任务。首先了解并熟悉WinCE操作系统,掌握WinCE系统下应用程序的开发与移植。其次,对WinCE系统的烧写及应用程序上电自启动的参数设置。最后,在硬件电路的完善、局域网络的搭建及现场开发终端的保护上进行量身定制。论文在结尾部分也对此套设备的优缺点进行分析,并进行最终的总结与展望。
[Abstract]:In order to monitor the abnormal condition in the sintering process of alumina , we collect the sound data of the aluminum finished product clinker and the roller kiln in the clinker kiln of the alumina cooler , save the collected sound data file on the terminal equipment ARM development board , and establish a small local area network , and then send the sound data stored on the terminal equipment ARM development board to the background station through the local area network . The workstation judges the abnormal state of the finished aluminum in the sintering process by the local area network , and provides the reference basis for the staff to eliminate the abnormal condition in time . This paper is a development platform based on the latest ARM11 microprocessor S3C6410 of 32 - bit Samsung Electronics Co . , Ltd . In this paper , the following tasks are done in order to accomplish the task of collecting , analyzing and displaying the field sound data . First of all , familiar with the WinCE operating system and mastering the development and porting of applications under the WinCE system . Secondly , the programming of the WinCE system and the parameter setting of the electric self - starting on the application program are mastered . Finally , the hardware circuit is improved , the local area network is set up and the protection of the field development terminal is customized . At the end of this paper , the advantages and disadvantages of this equipment are also analyzed , and the final conclusion and prospect are carried out .
