Abstract


With the development of science and technology, fly ash in the power plant is changing from an industrial waste into an industrial raw material. The urgency to improve the efficiency of the fly ash freight process supervision has emerged, when the market value of fly ash gradually increases.Video surveillance technology is always one of an applied technology which people pay a lot attention to. It is widely used in the business management by its accuracy, rapidity and abundant information.A solution of Supervision and management system based on on-screen display (OSD) technology and video surveillance technology was proposed in this paper, according to the requirement that needed to manage the fly ash silo in the power plant. Digital image processing technology, IC card technology and OSD technology were integrated into the solution to realize the supervision of fly ash silo in the local area network.IC card controller and character inserter were used in the system to display the characters about the plate number and the kind of fly ash on the video screen. So it was very easy to check the efficiency of the information by using the video screen. Information get and processing computer was used to capture the fly ash silo images and get the read time of IC cards, and it laid the foundation of recognising irregular image by using image processing.Supervision and management software of fly ash silo was designed by the VC programming tool, and it included the image of fly ash silo regular snapping, IC card read time accessing and image dividing by the time. Different Image recognizing algorithms were used to process the images according to its different feature. One image or a few would be fetched to represent the whole images of the segmentation. The image mode changed the traditional TV monitor mode which used 24 hours video recording to determine that the freight process was in working order, and the check time was reduced obviously.Application of the system in the plant will increase the management level for fly ash silo, and make good economic benefit.
