心跳体温检测装置的设计

Design of Heartbeat and Body Temperature Detection Device

由于市场上的心率体温检测仪器存在价格昂贵和检测准确率低的问题,因此设计了心跳体温检测装置。首先,系统的整体设计主要包括硬件电路设计和软件设计,选用STC89C52单片机作为系统的控制核心,采用DS18B20温度传感器完成温度测量,利用可以达到蜂鸣报警效果的有缘蜂鸣器,并选用LCD1602实时显示人体心跳和体温数据。其次,通过实物制作与调试,使用Proteus软件进行仿真,采用Protel DXP绘制印制电路板(Printed Circuit Board,PCB)线路图,并对其进行焊接。最后,待焊接完成后,对系统进行检测。检测结果表明,系统可以正常工作,满足设计要求。

Because the heart rate and temperature detection instruments in the market are expensive and have low detection accuracy,a heart rate and temperature detection device is designed.Firstly,the overall design of the system is introduced,mainly including hardware circuit design and software design.STC89C52 single chip microcomputer is used as the control core of the system,DS18B20 temperature sensor is used to complete the temperature measurement,the predestined buzzer that can achieve the buzzer alarm effect is used,and LCD1602 is used to display the human heartbeat and body temperature data in real time.Secondly,it is made and debugged in kind,simulated with Proteus Software,drawn Printed Circuit Board(PCB) circuit diagram with Protel DXP and welded.Finally,the system will be tested after welding.The test results show that the system can work normally and meet the design requirements.
