摘要
基于图像处理的火焰监视控制系统,由摄像头、A/D卡、计算机、火焰控制设备构成。用DS-400xMD/A卡采集图像,通过Lapalace算子检测边缘。摄像头将摄取的火焰图像信号送入图像监控系统,经D/A处理后实时显示并将压缩视频数据存储。图像监控系统按时间间隔从连续数字视频流中提取单帧数据,转存为BMP文件。系统对实单帧图像数据阈值分割处理后,由DCS再根据输入信号做出判断,当达到最大输出值尚不能控制火焰时进行报警。
The flame supervision and control system based on digital image processing consists of camera, A/D card, computer, flame control device. It gathers image with DS-400xM D/A card and examines the edge through the Lapalace operator. The flame image signal absorbed by the camera will be sent to the image supervision system, then it will be real-time displayed after being processed by D/A and the reduced video data will be saved. Withdrawn from the continual digital video frequency according to the time-gap by the image supervision system, the single frame data is saved to the BMP document. Be made the judgment by the DCS according to the input signal, the system gives a alarm message when the solid single frame image data achieves the maximum output which could not be controlled, after processed by threshold value division.
