Sha Wan Waterworks Based On Plc Automatic Control Management System Analysis And Design

We how make an old water factory send forth a new vitality through an automatic control system, how pass auto control the system make stability and credibility that the waterworks produces get a further exaltation, this is the great hard nut to crack that a lot of old water factories want to face at present.We not ability to the old thing carry on completely of negation, but can reserve its essence to make it to suit the social milieu in present more.Water factory auto’s controling system construction is a Jian huge work, if there is no a set of practical viable auto control system reformation plan, the automatic control system of water factory’s reforming probably can not complete very much, therefore water factory auto control the system reformation have to have the automatic control system of an integrity the design project.The design of automatic control system should around raise fluid matter and raise to supply water a safety and lower a medicine to consume and lower electricity to consume and lower to leak to consume for the target, only just can make like this water factory auto control system at hurl produce of, can attain an anticipant target.The thesis introduced the research background of automatic control system first and carried on an outline to the problem needed to be worked out, discussed the research meaning and importance of item and elaborated a system development’s method with related technique;The thesis put forward the design target of system and carried on detailed need analysis, including business need, function request and data need and non-function request to the system and gave the business flow chart of system, use a diagram, carried on to describe with the example;Design in the system in, carried on to the system total design and mold piece design, include automatic control etc. function mold piece, give mold piece the diagram, in proper order diagram and processing flow chart of the function structure diagram, type for designing, elaborated to design a contents in detail, carried on interface to design, the thesis finally carried on summary to the contents of research and elaborated my main work, point out thesis existence of shortage, and carried on an outlook to the further work.
