0.4KV Intelligent MCC Measurement&Control System Protective Unit-Driver Board
ABSTRACT
　　In the industrial and mining enterprises, in the production process, to ensure continuous MCC system reliability, as an important part of the bottom control unit need to configure a strong protection, measurement, remote functions.Development of intelligent MCC measurement&control system protective unit played a decisive role to achieve its function. To begin with, this paper analyzed the needs of intelligent MCC system protective unit, established a control system model of the logical relationship between factors, designed a block diagram for the system. Secondly, learned the relevant theoretical knowledge in-depth with the intelligent MCC system, mastered the principle of induction motor operation, selected the electrical components reasonably such as contact, non-contact switch, fuse, etc. Finally, based on functional requirements of intelligent MCC measurement&control system protective unit, from the principles of friendly man-machine interface, full-featured, easy to use, used development tools like AutoCAD and DXP 2004, designed this intelligent MCC measurement&control system protective unit-driver board.The hardware circuit completed the task that pick up, processing, analysis and display all the signal, the monitoring data is sent into the control center. Finally, processed data is obtained through LCD display. After various assessment on this designed intelligent MCC measurement&control system protective unit-driver board, carried out some related experiments, proved that this design has some reference value.
