摘要
目的:以单片机技术为核心设计一个低功耗、小型化的人体信号检测系统,为家庭监护设备提供一种可行的方案。方法:系统以MSP430F149为控制核心,能够实现数据实时采集与处理、数据存储、液晶显示和报警,以及键盘输入、USB通讯、上位机回放、处理等功能。结果:系统可实现生理、生化参数监测并上传到上位机。结论:该设计可为动态心电、血压等多参数人体信号的便携式检测建立一个软硬件的系统平台,实用性好。
Objective： This item presents a feasible scheme of home monitoring device which is a low power and miniaturization equipment for human signal detection, based on single-chip technology. Methods： Taking MSP430F149 as core, the realized functions of system contain real time data acquisition, data processing, data storage, LCD and alarming, keyboard as well as com- munication, replay and reprocessing by host computer. Results： The physiological and biochemical parameters are acquired by system and transmitted to host computer. Conclusions： This design provides a platform for multi-parameters portable detection just as dynamic ecg, ambulatory blood pressure, and so on. It has a good future for application.
