Design and Research on MCU Bluetooth Wireless Physiotherapy Device Controlled by Mobile Phone APP
摘要
Abstract
Objective To develop a wireless physiotherapy device controlled by mobile phone APP in order to achieve portability,high efficiency and aesthetics.Methods The system was designed based on STC12C5A60S2 single chip microcomputer chip.The Bluetooth module was used as the communication platform between the upper computer and the lower computer,and the capture/compare/PWM(CCP)module of the single chip microcomputer chip was used to output the treatment mode pulse width modulation(PWM)pulse electrical stimulation information to the human body,and the frequency domain characteristics and intensity of the human electromyography signal were used as the control parameter standard for the treatment of muscle fatigue.The hardware of the whole system was composed of main control module,Bluetooth connection module,electromyography amplification module,stimulation intensity control module,voltage coupling output module and power module.The upper computer program in the software was based on E4A(Easy Android)open source technology development platform,written in Chinese language;The lower computer program was based on Keil5 development platform and written in C language.Results The experiment showed that the system used the CCP pulse module in STC12C5A60S2 MCU chip,the output PWM pulse electrical stimulation had more powerful,the duty cycle of PWM pulse was easier to control.The wireless communication signal was within 3 m of the controllable distance of Bluetooth,and the physiotherapy module connected based on Bluetooth function could communicate smoothly with the mobile phone APP.Conclusion The research on the physiotherapy device+APP software using single-chip wireless Bluetooth technology has the characteristics of wide operating range,small size,convenient portability and strong output power and low cost,which not only supports mobile medical treatment but also can carry out local treatment for specific parts.This technology has important significance in the development of physiotherapy medicine field.关键词
