智能输液监控系统的设计与实现

文章设计一种智能输液监控系统,系统以STC89C52单片机为核心。在保证输液安全与卫生的前提下,实现自动检测并显示液体的点滴速度,控制滴速以及对异常情况进行声光报警等功能。采用红外对管检测滴速信号,利用带有偏心轮的步进电机控制液滴速度,软件模块基于模糊PID控制算法实现对步进电机转动角度的精准控制。该系统工作稳定,操作简便,成本低廉,在临床静脉输液中具有实际意义。

Design and implementation of intelligent infusion monitoring system

The article designs an intelligent infusion monitoring system,the system with the core of STC89C52 single-chip microcontroller .Under the premise of ensuring the safety and health of the infusion,controling drip rate and abnormal situations sound and light alarming.The system uses photoelectric tube to detect driping single, control droplet velocity with a stepper motor with an eccentric,the software module based on fuzzy PID control algorithm to achieve precise control of the stepper motor rotation angles.The system is stable, easy to operate, low cost, has practi-cal significance in the clinical intravenous infusion.
