中文摘要：

介绍了高炉风口CCD成像监测系统的研究现状、设计原理、系统组成和系统测试．高炉风口成像监测系统可将风口工作状态连续显示在操作室的监视器上，使高炉操作者能够随时观察到所监测风口亮度、活跃程度、喷煤状况、风口破损情况等现象，提高操作的准确性．利用数字图像处理技术对回旋区火焰图像进行处理，得到了回旋区内的温度分布．实验室测试结果表明，图像的数字化温度分析结果与实测鲒果的误差在3％以内，系统能够满足工程需要．

英文摘要：

The essay introduces the research status, the design principle, the composition and the test of the CCD-based imaging and monitoring system in the raceway of blast furnace. The CCD-based imaging and monitoring system in the raceway can show the running statement of the raceway in the monitor of operate room continuously, which enables the BF operator to observe the lightness and activity of raceway, the status of coal injection, the dilapidation of raceway and enhances the correctness of operate. Meanwhile, the system can transport the burning image of raceway to the computer, experimental results of which indicate the temperature error between the image-digitalize method and the measuring result is within three percent. The sustem can satisfy the demand of engineering.
