提出了一個由AT89C52單片機控制步進電機的實例。可以通過鍵盤輸入相關數據, 并根據需要, 實時對步進電機工作方式進行設置, 具有實時性和交互性的特點。該系統可應用于步進電機控制的大多數場合。實踐表明, 系統性能優于傳統的步進電機控制器。關鍵詞: 單片機; 步進電動機; 直流固態繼電器; 實時控制Con trol System of Stepp ingMotor Ba sed on AT89C52 ChipM icrocomputerMENGWu2sheng, L ILiang (College of Automatization, Northwestern Polytechnical Unversity, Xipan 710072, China)ABSTRACT: A stepp ing motor control system based on AT89C52 chip microcomputer was described.The data can be inputwith keyboard, and stepp ingmotorwas controlled by these data. According to the demand, users can set the workingmodel of stepp ingmotor in real2time. This system can be widely used in stepp ing motor controlling. The p ractice showed that the performance of this system outdid the tradi tional stepp ing motor controller.KEY WORDS: Chip microcomputer; Stepp ingmotor; DCSSR; Real2time control

The goal with this project was to make it possible for almost any mobile-phone to use ICQ and be able to communicate with other users! One other goal with this project was to lower the GPRS-traffic in the phone and make the ICQ-ing cheaper. A third goal was to make this service as easy to log-in to as possible. Anyone tried to fill a log-in screen with a WAP-browser should know what I mean. With Wapmess all you have to do is to write your login-url ONCE and then bookmark it in your phone, to make it available fast. :)

A semantic session analysis method partitioning Web usage logs is presented.Semantic W eb usage log preparation model enhances usage logs with semantic.The M arkov chain mode1 based on ontology semantic measurement is used to identi. ing which active session a request should belong to.The corn— petitive method is applied to determine the end of the sessions. Compared with other algorithms,more successfu1 sessions are additionally detected by semantic outlier analysis.
