The Research And Application About System Of Alternating Current Reversible Regulate Speed Based On The Distributed I/O

The system of alternating current reversible regulate speed based on the distributed I/O is a new kind of electrical driver method and it builds upon the computer technique, and develop quickly.In the spot of industrial produce, because of complicated environment, if it uses the concentrated I/O structure, all the control signals need send to the control center. It will be subjected to a lot of interferences, and make the control signal transmission failure. With the development of microcomputer technology, if it uses the distributed I/O structure, the control signal need send to the equipments neighborhood only, and then send to the control center together through the control module. It can reduce the rate of transmission failure, and make system simplification, maintenance expediently. And the system of alternating current reversible regulate speed uses the new technology about volatile frequency, it make the regulate speed capability of alternating current reversible regulate speed system not less than direct current reversible regulate speed system. The new technologies of distributed I/O structure and volatile frequency make the way of electrical driver development to alternating current.In the actual engineering application, this system is good to complete the control mission, obtaining the good control result. The system of alternating current reversible regulate speed based on distributed I/O structure as a kind of alternating current regulate speed system, it has the important application value and research value.
