基于C8051F020的智能理疗仪系统设计

摘要

针对当前理疗仪系统功能单一,实用性较低等问题,本文采用MCU C8051F020作为控制核心,其外围使用酸碱平衡电路、血氧和脉搏检测电路、血压检测电路、温度检测电路、指纹识别电路、GPRS收发等电路,设计了一款智能理疗仪系统.该系统实现了对血氧、血压、脉搏、人体温度等生理参数的实时监测、显示和存储,具有指纹识别功能,可以将监测到的人体生理参数、配置信息及用户使用信息实时发送到上位机,并以短信的方式发送到用户手机端.仿真实验表明:该系统的血氧分辨率为1％,血压分辨率为25帕,体温精度为0.1％,满足用户的实际要求,且该系统各个模式下运行稳定,具有一定的实用价值.%Due to traditional physiotherapeutic instrument simple and practical lowly,this paper introduce an intelligent physiotherapeutic instrument which uses microcontroller C8051F020 as control center device and acid base balance circuit,blood oxygen detection circuit,pulse detection circuit,blood pressure detection circuit,temperature detection circuit,fingerprint identification circuit,GPRS sending and receiving circuit are used as peripheral circuits.It is realized that various physiology parameters including blood oxygen,blood pressure,pulse and temperature can be real-time monitored,display and storage,besides,these parameters can be sent to PC and mobile phone.Experiments show that accuracy of blood oxygen reaches 1％,accuracy of blood pressure is 25Pa,accuracy of temperature is 0.1％,which is enough to satisfy users,and every module of proposed system is stable operation,so it has certain practical value.
