基于模糊PID的静脉输液监控系统

Intravenous infusion monitoring system based on fuzzy PID

为了有效地解决静脉输液过程中滴速难掌控、输液完毕无提示、手动更换储液瓶、患者舒适度差等问题,结合红外光电技术、嵌入式底层驱动技术、Android技术和模糊PID技术设计了一款监控系统.该系统采用红外光电传感器对输液过程进行实时监测,传感器底层驱动采集滴速、药液有无等信息.系统APK通过NDK获取传感器底层驱动的信息,且发送控制指令到执行器底层驱动以控制执行器更换储液瓶和滴速调整.实验结果表明,该系统能够准确地监测滴速且发出报警信号,提高安全性和患者舒适度.

In order to effectively solve the problem of dripping speed control in the process of intravenous infusion,no prompt after intravenous infusion,replace the liquid storage bottle manually and poor patient comfort,a monitoring system is designed based on optoelectronic technology,embedded underlying driver technology,Android technology and fuzzy PID technology.The system uses infrared photoelectric sensors to monitor the infusion process in real time.The driver of the sensor collects information such as the drip rate and the presence or absence of the drug.APK uses NDK to obtains information from the driver of the sensor,and send control commands to the driver of the actuator,replace the liquid storage bottle and adjust the drip speed with the actuator.Experimental results show that the system is able to accurately monitor the drip rate and send an alarm signal,improve safety and patient comfort.
