炼钢现场干扰严重、环境恶劣,人员设备复杂,转炉炉口火焰作为监视对象具有高温、高亮度的特殊性。针对炼钢工艺过程的特点,研制了炼钢工艺过程数字图像监控系统。系统重点解决了视频编解码、网络多播、多线程通信与同步等关键技术,并将采集到的火焰图像进行实时处理,获得的结果参与实时工业控制。现场应用表明,该系统满足炼钢工艺过程的监控要求,具有现场实用价值。 The scene of the steelmaking has serious interference, harsh environment and complicated personnel equipment. The flame of the converter mouth as a monitoring object has the characteristics of high temperature and high brightness. According to the characteristics of steelmaking process, a digital image monitoring system for steelmaking process was developed. The system focuses on solving key technologies such as video codec, network multicasting, multi-thread communication and synchronization, and real-time processing of the collected flame images. The obtained results are involved in real-time industrial control. Field application shows that the system meets the monitoring requirements of the steelmaking process and has practical value on site.
