The Studies Of Swage Treatment Based On Intelligence Control

Although city swage treatment system has great social benefit, it's running cost is high, and the economic benefit is low. In order to implement the swage treatment technique effectively, operate the treatment system steadily, guarantee the quantity of output water, the self-control technique applied in swage treatment to promote automatic level has become the key question in swage treatment.Take Dalian Quanshui swage treatment plant as background, incorporation with swage treatment craft, the application of PLC and it's network in swage treatment plant is discussed in this paper, and considered the action of on-line detection instrument in control system sufficiently. The control scheme of IPC + PLC and communication network scheme of PROPIBUS Fieldbus + fibre ring net is adopted in this system. This paper mainly introduced PLC, PROFIBUS Fieldbus, fibre ring not, swage treatment craft, the hardware and software disposal of control system and the automatic control system's implementation of swage treatment plant.Meanwhile, to the difficulties of intermittence, non-linearity, delay, and the online measurement hardness of direct control variable in aeration tank control, using the way of Intelligence control, the performing effectiveness of fuzzy control strategy is discussed. This paper implemented fuzzy control strategy on PLC by looking-up table, and applied in the Dalian Quanshui swage treatment plant.
