摘　　要：设计了一款心率变异性信号采集装置,由前端心电信号采集模块、下机位信号数据处理模块和上机位图像处理显示模块组成。前端心电信号采集模块主要使用AD8232芯片做传感器,该芯片可以在运动或者远程电极端放置时产生噪声的情况下来提取、放大和过滤微弱的生物电信号。下机位信号数据处理模块主要使用Arduino开发板,得到前端采集模块传来的心电信号之后,利用Arduino IDE平台编写好的程序对收集到的心电信号数据作处理。上机位图像处理显示模块需要使用processing软件,得到开发板传来的数据,将数据转换为图像,实时显示在屏幕。软件编程方面需要Arduino的IDE平台和上机位processing两款软件的配合使用。提出一种相对简单廉价的设计方案来获取心电图信号,通过心电图信号的采集、分析来判断身体的健康状况,对于检测多种心血管方面的疾病有着重要意义。This design is a heart rate variability(HRV) signal acquisition device, which consists of the front-end electrocardiograph(ECG) signal acquisition module, the lower position signal data processing module and the upper position image processing and display module. The front-end ECG signal acquisition module mainly utilises the AD8232 chip as a sensor, which can extract, amplify and filter weak bioelectrical signals under the condition of noise generated by movement or remote electrical extremes. The down position signal data processing module mainly utilises the Arduino development board to obtain the ECG signals from the front-end acquisition module, and then processes the collected ECG signal data with a program written on the Arduino IDE platform. The image processing and display module needs to use processing software to obtain the data from the development board, convert the data into images and display them on the screen in real time. In terms of software programming, the cooperation between Arduino′s IDE platform and processing software is required. This design proposes a relatively simple and cheap design scheme to obtain ECG signals, and judge the health status of the body through the acquisition and analysis of ECG signals, which is of great significance for the detection of a variety of cardiovascular diseases.
