ABSTRACT

The development of the control system of crosscut machine of corrugated cardboard, from the development of electric power electronic technology and technology of computer of the control theory in controlling the application of the field ,based on the present current situation, has recommended controlling field development to study the general situation in the electrical machinery both at home and abroad. Through atting corrugated cardboard crosscut machine and his the surveys of control systems, draw. Get in touch with the application background with real subject, exchange the control system and develop schemes after putting forward WHD 2000 type corrugated cardboard crosscut machine.

This system adopt worker accuse of machine responsible for user interface and order form task management as top management computer. By one-chip computer receive computers top management and send processing task and debug order of of, It control finish at converter it process taskses it debug and work, It check labor and materials and carry out corresponding treatment of at the states of each the buttons, Measurement is mainly cut  the  electrical machineries position, measure the cardboard to enter to the speed, measuring the converter parameter, fault alarm etc. In the development of the  system, has set up two steps of mathematics models which control the target at first. To exchanging accurate to make a reservation control electrical machinery, this text according to cutting at one the girth relations between the  B₀ of roller divide into three kinds of situations the length L₀ of paper, Promptly: L> P , L =P , L <P .

Communication offer and use layers of the encapsulation and seal ofves of data by chain way one, hide physics layers of communication the differences of detail, offer perfect mistakes control and at flow controlling mechanism, offer one a piece of a safe one, to have mistake, orderly source communication chain distance to reach purpose s for using floor. This layer finish finishing frame, transmit and control , flow control , the mistake measures and spread mechanism, etc. again mainly, Offer the unified communication interface for using. It uses one face the ones of user offer interface systematically, work way choose, order information input management, daily record the organization functions of file of inquiring about etc mainly.

The reconstruction and the design based on the above method have been pass the testing and running and applied in practice. The designed objective has been achieved. The ideas and means have the instructive meaning for doing the similar projects.

Key Words:  Corrugated cardboard   Crosscut machine   Flyingshear
