通过对目前市场上电子治疗仪的分析，在研究其电子治疗仪工作原理及AT89C51SND1C的基础上，提出了一种基于嵌入式器件AT89C51SND1C的电子治疗仪设计方案，利用嵌入式器件89C51SND1C的MP3功能，产生中频信号与音频信号，并将二者进行调制，通过放大、变压器隔离，输出到电极片上。通过电极片对人体治疗部位的覆盖，使人体感知随音乐信号起伏变化的电流刺激，引起肌肉收缩和舒张，以缓解疲劳和治疗周围神经损伤。
- Abstract:
- By analyzing the electronic troatment instrument on the current marker,the paper puts forward an-electronic treatment in strument based on AT89C51SNDIC on basic of studying is operation principleThe MP3 function of the embedded Chip 89C51SND1C facilitates to produce medium frequency signal and audio frequency signal, which will be modulated and transferred to the electrode slice after they are magnified and transformer-insulated.The human body perceives the electronic current stimulation changing along with the rise and fall of the musical signals when the human body parts to be treated are covered with electrode slices. The stimulation will cause muscle constringency and relaxation, thus alleviating fatigue and curing the damaged peripheral nerves.
