Research On The Application Of Fuzzy Clustering Algorithms In A Personalized Web Information Search Assistant

The electric valve actuating controller is a main section of the electric valve actuator .The author in this Master Paper analyzes in detail and deeply the electric valve actuators and their controllers at home and abroad, and adopts to some experience successfully.Based on them, the author then develops a new type of intelligent electric valve actuating controller for remote controlling. This type of electric valve actuating controller with the core of micro controller 80C31 possesses not only the functions of a normal regulating device, such as testing, detecting, controlling and regulating, but more functions which helps to realize the remote controlling, the real-time display of various parameters, the diagnosis of fault and the failure protection and the soft judging of reference parameters coming from remote control center.The designing principles of the article are effectiveness, conveniences, safety and reliability. The author has a whole design of the electric valve actuating control system. The software used by control system in assembly language is also given in this article. Furthermore, the system has a variety of software and hardware protective measures so as to improve the anti-interference abilities of this instrument. The system presents by the experimental result that the whole design is feasible and reliable.
