前言：
電路城在之前有網(wǎng)友分享過一個老外的設計，即基于AD8232心電心率圖監(jiān)測測量（鏈接：https://www.cirmall.com/circuit/2037），該設計主要闡述的是基于AD8232芯片對ECG及其他生物電測量應用的集成信號調理模塊。然后在具有運動或遠程電極放置產(chǎn)生的噪聲的情況下提取、放大及過濾微弱的生物電信號。 本設計介紹的是心率監(jiān)測器轉接板模塊，能夠智能化的將ECG信號模擬信號轉換成心率數(shù)據(jù)。
心率監(jiān)測器轉接板概述：
The Heart Rate Monitor Interface (HRMI) is an intelligent peripheral device that converts the ECG signal from Polar Electro Heart Rate Monitor (HRM) transmitters into easy-to-use heart rate data. It implements a sophisticated algorithm for computing an average heart rate even with noisy or intermittent data from the transmitter. The HRMI also provides analog 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?
? 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
