基于ARM的主从式体表子宫肌电(EHG)数据采集系统

EHG Data Acquisition System Based on ARM with Host-slave Structure

目的:为了能够更加全面而准确地反映产妇分娩过程中产力的状况,设计一套基于ARM硬件架构的便携式监护仪。方法:该系统采用主从式结构设计,主机采用ARM9处理器并嵌WinCE系统达到多任务的设计目标,从机采用51系列单片机以实现数据的实时采集。结果:经实验测试,体表子宫肌电(EHG)数据采集系统为产程监护提供了较为有力的研究工具,且方便可靠,人机界面友好。结论:该系统的研究也为相关数据采集仪器的开发提供了一种值得借鉴的研究方法。

Objective To design a handy labor monitor based on ARM hardware structure so that the condition of pregnant women can be reflected more accurately and completely. Methods The host-slave mode was adopted, which was composed of host machine based on ARM and embedded WinCE operating system. The slave machine used the 51 single chip to acquire data. Results This system was convenient and stable, and the interface is friendly. Conclusion The study of this system can be used for reference for the development of related data acquisition machine.
