| Quaryside Portainers (QP for abbreviation) are mainly mechinery for loading and unloading containers between container-ships and harbors,whose loading or unloading capacity decide containers harbor operation production-rate.High production-rate is primely destination of QP production-rate.lt impels QP to develop in the way of huge-type high-speed trolley ,automation, intelligent and environment -prevention.To increase the production-rate of QP,people adopt a series of techniques and measures to improving abilities of QP:(1)Reseach and develop totally automation technology, such as automation laocation, identification and evasion the obstacle in the way of container's motion, industrial manipulator wristlock etc.(2)Application of Two-box spreader to improve loading mechanism which can averagely promote 25 percent of production-rate.(3)Application of two trolleys to improve the method of loading.As the technology of loading equipment and method of loading gradually becomes perfect,developing and researching new sway-prevention or how to improve traditional sway-prevention is the key problem we must be faced with.Seesaw-beam sway-prevention mechanism don't need auxiliary steel wire and has a simple construct. This paper improve the dampen hydraulic circuit to adopt variable Load and enhance the degree of automation, meanwhile apply in the economizing tech -nology to low the hydraulic failure.This paper adopts intelligent control ,different from the model in way of classic and modern control theory, whose mainly aims at controller it self ,but at object being controlled.classic and modern control theory look feeble in disposing the problem such as sway-prevention.This paper disserts intelligent control as following two facets: Fuzzy control concludes from people's control experiments of real production into fuzzy control rules set,as a method of language control ,it need not know the exact mathematical model Introducing fuzzy control' mainly overcome the difficult brought byinexactitude and voice in the process of control to compensate the deficiency in hard-established original weights of neutral network..But pure fuzzy control has not perfect control rules and feeble self -study ,so introducing neutral network creates subjection function and edits fuzzy control rules. Neutral network and fuzzy control together build fuzzy- neutral network controller ,which is the core content of this paper.Besides,introducing the PLC control enhance the degree of the intelligence and automation to realize adjustment damper and automatically warning. An expectd result of dumping,intelligent and automatical control of improved sway-prevention seesaw-beam mechanism and hydraulic system with less obstacles is proved in theory. |
