單片機液體點滴速度控制裝置設計摘要：本系統採用主站控制從站的有線監控方式實現醫療輸液過程的羣控。其中主站採用586PC機作爲主控制器，用Visual Basic 6.0面向對象的32位可視化進階語言編寫人機介面，從而使得系統具有介面友好，使用方便的特點。主站能定點和巡迴檢測並顯示從站資訊，對從站的報警資訊進行實時提示等。
從站採用單片機AT89C51作爲核心器件來實現液體滴速的檢測、滴速異常報警、滴速的'設定及控制等，其軟件採用MCS-51彙編語言實現。
主站與從站之間的通信採用RS-485總線連接，有效地實現了主從式網絡設計。在主站的VB設計中用到了專用串行通訊控件—MCSComm控件。關鍵詞：液體點滴；單片機；串行通訊；VB；RS-485總線
The Single-Chip Controlling Device Designing
Of The Velocity of The TransfusionABSTRACT：The system use the cable surveillance of the home site control subordinate site method to realize the distribute control of the medical transfusion process. We use the 586 PC as the home site controller, and use VB 6.0 the Object-Oriented 32-bit visual programming language to build the man-machine interface, in this way, the system has friendly interface and easy to use characteristics. The home site can detect and display the information of the subordinate site both pointing position and itinerantly, and give a real-time indication of warning information from the subordinate site.
The subordinate site use AT89C51 Single-chip controller as the core instrument to realize the detection of the transfusion current velocity, the abnormal current velocity alarming, the setup and control of the current velocity, etc. This software is built by MCS-51 assembly language programming.
We use the RS-485 bus unit to connect the communication of the home site and the subordinate site, this can greatly realize the home site and subordinate site network design. We use the MCSComm control component as the specially serial communication component in the VB programming of the home ords: Transfusion；One_chip Computer；Serial Communication；VB；RS-485 Bus Unit..........................
