【摘要】 世界上的现代化连铸生产，正在不断地提高它的自动化程度和钢产品质量，以获取更大的效益，因此采用了许多先进的技术。下渣检测系统作为当代最先进的连铸生产线的配套环节技术，其目的是尽可能减少从大包转移到中间包的熔渣，以获得最大的钢产量。最近，中国自行研制的第一台新型的下渣检测系统在杭州钢铁公司开发成功，该系统由具有高增益、强抗干扰的检测仪器，工作在1400℃的传感器，以及计算机实时监控系统组成。本文提出了实时数据处理系统的设计方案，该方案采用个人计算机(PC)和数据采集卡(DAQ)作为硬件支撑平台，并利用基于虚拟机的．NET技术实现。通过硬件接口电路，配置实时数据处理软件的计算机和下渣检测仪器组成了功能更强大的系统。该系统实现了下渣连铸检测的实时数据处理功能，包括实时显示、存储、查询以及连铸过程信号的打印。同时实时显示还起到了监控整个系统运行的作用。在100吨钢包连铸生产线上新系统运行并取得了预期的效果。 本文首先介绍了下渣检测系统的工业背景和基于虚拟机平台的实时性研究现状。然后介绍了一种“软”实时技术，智能垃圾收集方案，该方案是在设计过程中提出的实时性解决方案。本文的第四章介绍了软件系统的总体设计，以及各个功能模块和软件设计中的关键算法，最后给出了智能垃圾收集方案的应用。在课题小结部分，介绍了软件的功能，并给出了现场运行的实测曲线。最后进行了项目的总结和展望。更多还原

【Abstract】 Modern continuous casting product in the world is being continuously improved on its automatization and the quality of steel to get higher benefit. For this reason, many advanced technologies are used. One of them is a ladle slag detection system. The aim is to obtain maximum yield form each ladle at minimum transfer of slag from ladle to tundish. Recently the first novel slag detection system developed in China has been completed in Hangzhou steel company with successful results. It includes a detection instrument with high gain, strong anti-interference and a sensor working at about 1400, and a computer monitor system to enhance its function as well. According to the object-oriented design methods, a real-time data processing system is proposed and realized by means of a personal computer (PC) with a data acquisition board (DAQ). The general idea is based on a virtual machine using .NET technology. Via an interface circuit the slag detection system and the PC with such a software system constitute a more powerful one. That can implement the real-time data processing functions for slag detection of continuous casting ladle with real-time display, storage, inquiry, and print of the slag signal obtained at the end of pouring of each ladle. At the same time, the display acts as a monitor to image the operation of the whole system. The new system has been tested on the continuous caster with 100t ladles and prospective results are obtained.The industrial background of the slag detection system and the general idea of the real-time system based on virtual machines are introduced firstly in this chapter. And then the intelligent garbage collection (GC) is given, which is extracted form the design of the real-time system. The general design, function modules and key algorithms of the software are described in Chapter 4. As a result, the typical curves recorded in on-line tests are given in the Summery.更多还原
