摘　　要：研制了一种智能输液监控系统.该系统以单片机MSP430为核心,可以实现自动检测并显示液体的点滴速度、用键盘设定点滴速度和对异常情况进行声光报警等功能.采用红外光电传感器检测液位信号,通过硬件滤波和保护装置消除杂散光干扰.另外,通过下位机与上位机之间的串行通信,系统还实现了对多台下位机进行远程的监控与管理.测试结果表明该系统工作稳定、响应速度快、操作简便,在医疗卫生领域中具有广泛的应用前景.The intelligent monitoring system for the transfusion was developed with MSP430 single chip processor used as a core. The system realizes auto-detection and display of the drip velocity. The drip velocity can be set by keyboard and the abnormal event alarm has achieved. The signal of the liquid level was detected by the infrared photoelectric sensor, and the interference of abnormal light was eliminated by the hardware filter and the protect device. In addition, the remote monitoring and managing of several lower computers was achieved by serial communication. The performance, fast in response and simple in operation. treatment field. experiment results show that the system is stable in The system has bright application future in medical
