摘　　要：针对传统人工液监控系统控制精度低、人力物力耗费大、安全度不够等缺点,本研究提出了一种基于ZigBee技术、光电检测技术与电机控制技术的输液监控系统的设计方法。考虑到对输液滴速控制的可靠性与精确性,采用PID控制算法进行液滴速度的闭环精确控制。实验证明,系统工作稳定,实现了输液过程中的远程监控功能,达到了对液滴速度的控制要求。Traditional infusion monitoring system has the disadvantages of low accuracy, high consumption of human resources, and low security. In response to these shortages, we put forward a new design scheme based on Zigbee technology, photoelectric detection technology and motor control technology. In view of the reliability and accuracy of the control, PID software algorithm is used in software design to measure and calculate the dropping rate, and a transfer system with the closed loop is formed to realize accurate control. Proved by experiments, the system works stably. It will not only realize the function of remote monitoring in the process of transfusion, but also meet the requirements of controlling dropping rate.
