基于STM32和MT2511的智能监护系统

Intelligent Monitoring System based on Stm32 and MT2511

随着老龄化进程的加快以及慢性病患病率的提高,早期的医疗监护已经成为一个重要的研究方向,而作为普通家庭使用的智能化的可穿戴监护系统具有广阔的市场应用前景。据此,本文设计了一种智能腕式可穿戴健康监护系统设备,该设备功耗低、分立元件少、精度高,便携穿戴,可采集心率、心电、人体状态参数,并通过软件滤波、算法优化,处理得出佩戴者血压等实时生理参数及是否跌倒等,异常时立即发出警报并通过北斗导航准确显示出坐标位置。本系统主控MCU为STM32F405RGT6,脉搏、心电等生理数据采集使用MT2511,坐标定位芯片采用北斗导航的UC6225,人体状态参数由MPU6050读取,通过CC2540蓝牙模块与手机传输数据。

Early medical care has become an important research direction with the acceleration of the aging process and the increase of the prevalence of chronic diseases. The intelligent wearable monitoring system used by the ordinary family has broad market application prospect. In view of this, a smart wrist wearable health monitoring system device is designed in this paper. The equipment has the advantages of low power consumption, few discrete components, high precision and portable wear. And it can have real-time collection of blood pressure, heart rate, EKG, fall monitoring and other physiological and human state parameters and get the user＇s health status through the software algorithm optimization, processing and etc., send the alarm immediately for any abnormality and accurately show the coordinates of the location through the Beidou navigation. STM32F405RGT6 chip is selected as the main control of the system MCU, MT2511 is used for blood pressure, heart rate and EKG acquisition. The anti-jamming chip UC6225 based on the Beidou navigation is used as the coordinate positioning chip, the human body parameters are read by the six-axis acceleration sensor MPU6050, and human physiological data and etc. are transmitted through CC2540 Bluetooth module to the mobile phone
