基于FPGA的数字心率监测仪设计

摘要

This paper introduces a method to design a digital heart rate monitor based on field - programmable gate array (FPGA). The electrical signal of pulse is collected by the pulse transducer, after the pre - processing and A/D conversion, the signal is given to the FPGA for data storage and processing. The monitor has the functions of real - time monitoring and displaying the heart rate parameters, automatic alarm. The system has advantages in anti -jamming and integration with easy expansion.%提出了一种基于现场可编程门阵列( FPGA)的数字心率监测仪的设计方案.由脉搏传感器采集到的脉搏信号经过预处理和模/数转换,送给FPGA进行数据存储及处理,实现实时监测与显示心率参数、自动报警等功能,具有抗干扰性好、集成度高和易于扩展的优点.
