摘　　要：为了克服心脏疫病突发就医不及的安全隐患,早期心脏疾病早发现、早治疗,开发了一种基于嵌入式微控制器的小型化心电信号检测系统,该系统包含心电信号采集硬件、控制系统软件以及心率转换算法设计,实现对被测者心电图、呼吸波及心率的获取,利用串口通信方式,上传给串口屏显示模块,并且设计了一套基于心电信号检测的Qt上位机软件系统,可实现对心电数据的采集与查看生理和病理状态。测试结果验证表明,该系统可在确保高准确度及低功耗的条件下获取被测者心电图与呼吸波形,相应的,能够准确计算出心率值并显示。In order to overcome the safety hazard of sudden heart disease,early detection and early treatment of heart disease,a miniature ECG signal detection system based on embedded microcontroller has been developed,which includes ECG signal acquisition hardware and control system software and heart rate conversion algorithm design to achieve the acquisition of the testee’s electrocardiogram,respiratory wave and heart rate,serial communication is used to upload to the serial screen display module,and a set of Qt host computer software based on ECG signal detection is designed. The system can realize the collection of ECG data and view the physiological and pathological status. The test result verification shows that the system can obtain the subject’s ECG and respiratory waveform under the conditions of ensuring high accuracy and low power consumption,and accordingly,it can accurately calculate and display the heart rate value.
