摘要
基于单片机的液体点滴速度监控系统是一个能够代替医务人员监控病人点滴速度的智能化系统。该系统提出了一种点滴速度监控装置的设计方法,可用按键控制点滴速度并通过显示装置显示当前速度,当药液低于一定标准可通过蜂鸣器报警,系统采用了AT89C51作为核心处理单元,光敏传感器检测液体的滴数,控制夹位置通过步进电机进行调整来控制点滴速度,通过多种方案对比,该系统操作简便,特别进行了软件仿真设计,更具科学性可将理论运用于医疗实际中。
Liquid dropping speed monitoring system based on SCM is an intelligent system which can take the place of the medical staff to monitor the patients＇ dropping speed.The system presents a design method of the speed monitoring device which can use buttons to control the dropping speed and display the current speed through the display device.When the liquid medicine is below a certain standard,the buzzer can be used to give an alarm.The system uses AT89C51 as the core processing unit.The photosensitive sensor is used to test the numbers of the liquid drop.With the use of stepping motor,the control clip position is adjusted to control the speed.Through comparison,this system is proved to be simple to operate.It has software simulation design and is more scientific.The theory can be used in the medical practice.
