| With the continuous development of science and technology and the continuous improvement of people’s quality of life,people no longer focus on food and clothing,and will not go to the hospital for treatment until the body has serious diseases,but pay more attention to body prevention and health management.This has given rise to the demand for the collection and management of people’s health information.Mastering this information not only allows us to pay more attention to our own body regulation in daily life,but also provides personal daily health information to doctors in time when diseases occur,so that doctors can quickly and accurately make judgments and make the right treatment plan.Due to its own characteristics,traditional medical equipment is subject to time and space constraints when it is widely used,and cannot meet people’s rapid and convenient application needs.As a result,fast and convenient mobile health service equipment and technology have gradually become the research and development hotspot of today’s scientific research institutions and enterprises.Compared with traditional medical equipment,mobile terminal health service equipment has the advantages of small size,portability,and low development and maintenance costs.As an important part of intelligent medical care,it will have an important impact on intelligent medical care.Among many health indicators,heart rate is one of the most important indicators in the human body,which can accurately reflect the most basic conditions of the human heart.At present,the heart rate detection system on the market is mainly provided by large-scale medical equipment institutions.It has the advantages of high data processing speed and high calculation accuracy,and at the same time,it has the disadvantage of being too large to be portable.In order to meet the convenience needs of users,this article will design a portable ECG monitoring system,which can realize the real-time measurement and collection of heart rate information,and use Bluetooth technology to synchronously transmit the collected data to the mobile terminal.In this paper,based on the full research and analysis of the current status of the use of portable medical monitoring systems at domestic and foreign,the current more cutting-edge sensing technology and communication technology are selected to design and develop a portable heart rate monitoring system.The circuit of the system is based on EFM32G230F64 MCU,and the system heart rate acquisition circuit,Bluetooth 5.0 circuit,OLED circuit and RTC circuit are designed;The detection and acquisition of heart rate signal adopts the photoplethysmography(PPG),and the Android application system of the mobile terminal corresponding to the heart rate collector is designed.The system can collect and monitor the heart rate data of the monitored person in time,and send it to the mobile terminal.Then upload it to the central server through the mobile terminal,so as to achieve the early warning function of abnormal health of patients. |
