Research And Development Of Intelligent Body Control Electrotherapy Apparatus

Today,the office worker affected by the bad living habit,more older people,patients who can't pay medical expenses urgently need a new kind of health care instrument with low cost,comprehensive functions,and reliable performance.Aiming at this social demand,in this thesis,an intelligent body-controlled meridian electrotherapy instrument is designed based on STM32.This instrument can be used by doctors to diagnose patients,and also can be used for the user's self-care,with the features of intelligent,convenient operation and safety.Firstly,this thesis summarizes the advantages and disadvantages of all the electrotherapy apparatus,and clearly understands the development trend of electrotherapy apparatus.According to the clinical experience of electrotherapy,the four key factors that affect the electrotherapeutic effect are the waveform,frequency,intensity and treatment time.Based on the advantages and disadvantages of the electrotherapy products in the past dynasties,the functional indexes of this instrument are formulated,the overall design scheme is set up and the hardware part and software part are divided.In the overall design scheme of hardware,it is necessary to build STM32 minimum system and design the power supply circuit,prescription electric modulation circuit,LCD/OLED touch screen interface circuit and select wireless communication module,LCD display,disengagement/excessive current detection module,pulse detection module.Finally the prototype of the instrument is made,and after a simple test,the software part began to work.In software overall design,firstly ?C/OS-II the embedded operating system and?C/GUI embedded graphic interactive system are transplanted,graphical interface design,the prescription electricity generating program design,program design,intelligent roaming electrodes prescription current fuzzy controller design,?C/OS-II system on the touch screen and touch task design,wireless signal to send and receive task design and Android APP client development environment is completed,the instrument and computer data communication is realized.Finally,the hardware and software of this instrument have been tested in all directions to verify the feasibility of the design scheme.The test project includes hardware circuit test,software program test and overall system debugging.The test results show that the system design of this project meets the expected requirements.
