基于ZigBee技术的输液监测系统设计

The design of a system of infusion monitoring based on ZigBee

本研究设计了一种以MSP430F149REV和CC2530F256为核心的多功能、低功耗的输液监测系统,检测部分采用红外原理来实现对液滴的检测,利用调制解调技术减小外界光的干扰,运用鉴频、整形等电路来提高整个系统的灵敏度和稳定性,并具有余液显示,声光报警等功能.同时将采集到的数据通过以CC2530为核心的ZigBee网络传输到工作站的PC机上,医护人员能随时了解输液的动态信息,减少人员消耗,同时也方便管理.整个系统在硬件、软件上都做了低功耗处理,使耗能达到最小,直接采用3V干电池供电即可.

This paper designed of a system of infusion detection that multi-function and low power consumption which used MSP430F149 and CC2530 as its core, the detection part used infrared techriology to measure liquid drop, and the interference from light around was reduced using the modulation demodulation method, used frequency discriminating circuit and wave shaping circuit to improve the system＇s sensibility and stability, the system also can give a surplus fluid amount and a sound-light alarm automatically. Meanwhile, transmitted the information to personal computer of workstation by ZigBee net which used CC2530 as its core, so doctors and nurse can know the muhidate information of infusion at all times, it can reduce the personnel consumption and it also convenient to manage. The whole system was dealt with low power consumption, and consumption was minimum, it can work in 3V by dry batter.
