摘　　要：设计了一种基于MK60DN512ZVLQ10单片机的智能心率仪,以心率血氧浓度模块MAX30100为传感器,采用TFTLCD作为显示模块,将一个五轴按键集成在显示模块,结合两个不同颜色的LED和有源蜂鸣器来进行声光报警。软件部分的程序代码用C语言进行编写。单片机对MAX30100进行读写寄存器和地址操作,可接收来自传感器的一个8字节的数字信号,该信号经相关软件算法,可得出心率值和血氧浓度值并显示在TFT-LCD上。用户可通过按键设定报警阈值。利用Altium Designer完成硬件电路设计,在IAR编译器环境下完成了程序代码编写和系统调试,最终的系统能够准确地测量心率值和血氧浓度值。An intelligent heart rate meter based on MK60DN512ZVLQ10 single chip is designed, which uses the heart rate oxygen concentration module MAX30100 as the sensor and the TFT-LCD as the display module.A five axis key is integrated into the display module.The sound and light alarm is carried out with two different colors of LED and active buzzer. The program code of the software is written in the C language. MAX30100 uses a typical I^2C communication mode. MCU can receive an eight bytes of the digital signal from sensor by reading and writing the registers and address of MAX30100.The digital signal can beconverted into the value of heart rate and blood oxygen concentration through the related software algorithm,then displayed on TFT-LCD.The user can set the alarm threshold through the key, once measured heart rate exceeds the alarm threshold which set by the user, it will alarm to alert the user.Altium Designer is used to complete the design of hardware circuit.Complete the programming and system debugging in the IAR compiler environment. The resulting system can accurately measure heart rate and oxygen concentration.
