心率监测器转接板电路+PCB源文件+源代码-电路方案

前言: 电路城在之前有网友分享过一个老外的设计，即基于AD8232心电心率图监测测量（链接:https://www.cirmall.com/circuit/2037），该设计主要阐述的是基于AD8232芯片对ECG及其他生物电测量应用的集成信号调理模块。然后在具有运动或远程电极放置产生的噪声的情况下提取、放大及过滤微弱的生物电信号。本设计介绍的是心率监测器转接板模块，能够智能化的将ECG信号模拟信号转换成心率数据。 心率监测器转接板概述: The Heart Rate Monitor Interface (HRMI) is an intelligent peripheral device that converts the ECG signal from Polar ElectroHeart Rate Monitor (HRM) transmitters into easy-to-use heart rate data. It implements a sophisticated algorithm forcomputing an average heart rate even with noisy or intermittent data from the transmitter. The HRMI also providesanalog inputs and a digital input/output utility port to ease integration into custom applications. Features • Multiple interfaces: USB, Logic-level serial and I2CTM • Dual heart rate processing algorithms: averaged and raw • Uses the RMCM01 Polar OEM receiver • Compatible with coded and non-coded Polar transmitters including T31, T31C, T61C and Wearlink:registered: • 32-entry heart rate data history buffer • Four 8-bit ADC inputs • Up to a 5 channel digital input/output utility port • Simple command/response interface • Programmable power-on default operation Applications • Custom exercise equipment • Portable heart rate monitoring devices • Bio-feedback devices • Heart beat aware body-worn electronics 硬件连接示意图: 附件内容截图: 源文出处:https://danjuliodesigns.com/sparkfun/sparkfun.html
