利用单片机设计并制作一个智能化的液体点滴速度监测与控制装置。该装置由水滴速度测试系统、水速控制系统、气泡空液阻塞检测系统，电源异常检测系统，显示滴速装置、故障处理系统，报警系统等系统组成。应用光透射原理监测滴速，利用控制步进电动机的转速来控制点滴速度，利用红外二极管监测液面高度，利用压力传感器检测导管堵塞，利用超声传感器气泡。点滴速度可用键盘来设定同时在水到达警戒线以下时能发出报警信号。-The use of single-chip design and production of an intelligent the liquid drip speed monitoring and control device. The device consists of the droplet speed test system, the water speed control system, bubbles empty liquid blockage detection system, power supply anomaly detection system, display the drip rate device, fault handling system, alarm system and other system components. The application of light transmission principle of monitoring the drip rate, using the rotational speed of the control of the stepping motor to control the velocity of the drip, using the liquid level height of the infrared diode monitoring catheter blockage is detected by the pressure sensor, ultrasonic sensor bubbles. Drip speed of the keyboard can be used to set the alarm signal can be issued at the same time in the water reaches the cordon following.
