| Abstract: | The method of serial communication based on Visual Basic under the Windows is introduced. On the basis of discussing the general principle of this topic, the communication control method and the API function call method for serial communication are analysed in detail. At the last, the thyristor speed regulation system of DC motor applied for grate drive of boiler is given as an example, the set up of the supervisory control system with VB, the serial communication between PC with 89C51 single chip microcomputer and the formation of the user operation interface are introduced .Good results are achieved. |
