| 摘 要： | 为了改变医院输液系统的非智能化，设计一个液体点滴自动报警装置系统。该系统装置是由主站控制多个从站输液速度，并在从站液位过低时将自动报警。该系统设计是以单片机为最小控制单元。由主站控制、从站控制、滴速测量、容量测量、报警等模块构成。通过RS-232串行通信总线，根据自定协议，该系统设计实现由一个主站控制多个从站的液体点滴速度检测装置，1分钟内滴数范围达到20—150滴。

| Abstract: | In order to change the non-intelligent hospital transfusion system,we design an apparatus system to monitor and control liquid drop speed.The system master station controls the liquid drop speed of several slave stations,and alarms when the liquid level of slave stations is lower.Based on the least control unit of MCU and FPGA,the system consists of master station control module,slave station control module,spare station control module,liquid speed testing module,capability testing module and alarm module.B... |
