The Research Of A Collection And Processing System Of Alum Image

As the advancement of industry and people's life level, the demand of water quality is more and more great. It's the key to implement the full-scale automatization of water plant how to design and develop more rational control of adding material. And figuring out the precise quantity control of precipitator alum in the deposition pools is an important problem of the whole water industry. It can't realize adding precipitator by measure, which traditionally depends on naked eyes to detect the quantity of adding alum in the deposition pools. As a result, there are the problems such as consuming alum without measure and difficulty to control water quality, which isn't adaptive to great demand of water quality.Currently, the digital image processing is applied widely in every day of life. Along with the rapid development and application of the digital camera, the collection and processing system based on the digital camera has obtained wide attention and application, which has higher resolution and cheaper cost than the traditional fashion of collection image. However, in the practice use, the research of the application methods to overcome the practice limit and to enhance the anti-disturb ability of the system is still a task of great challenge.This paper describes the collection and processing system of alum based on the digital camera for the adding control of deposition pools in a water plant, and gives a set of designing thinking, designing scheme and designing measure.Because of the characters in the alum image: strong disturbances, low contrast and random arrangement of alum grain, in the designing of the system we sort theimages collected from digital camera and get the corresponding control of adding alum through three steps: pre-operation, vein analysis and particle processing. In the whole designing of the system, present arithmetic can't be used to get the perfect result, so we proposed some improved arithmetic in each step. The experiments show that the arithmetic is effective, and this system is high efficiency and reliable.
