摘　　要：本设计硬件主要以STC89C52单片机为控制处理单元,红外线传感器作为心率跳动的感应器,GSM模块为无线通信模块。通过红外线传感器进行心率的信号输入,经过滤波放大后输入单片机系统中,最后在LCD1602液晶显示屏中显示心跳次数,当心跳数超过或低于阀值时通过蜂鸣器对使用者进行报警,同时通过GSM模块发送短信告知他人。本设计实现了以下两个功能:一是做到了实时监测显示心率功能,让使用者了解自身心率情况;二是做到了通过无线通信功能(以发送短信的方式),让他人知道使用者现在的心率情况。The hardware of this design mainly uses STC89C52 MCU as control and processing unit,infrared sensor as heart rate beating sensor,GSM module as wireless communication module.The heart rate signal is input by infrared sensor,and then input into the single-chip microcomputer system after filtering and amplification.Finally,the number of heartbeat is displayed on the LCD1602.When the number of careful jumps exceeds or is lower than the threshold value,the buzzer will warn the user,and at the same time,SMS will be sent to inform others through GSM module.This design realizes the following two functions:one is to achieve the function of real-time monitoring and displaying heart rate,so that users can understand their own heart rate;the other is to let others know the current heart rate of users through wireless communication function(by sending short messages).
