毕业设计-基于单片机的低频疼痛治疗仪设计，共27页，12076字
摘 要
随着科技在不断进步，人们对疼痛的机理也掌握的越来越多，低频高压电疗法，既能兴奋感觉神经，又能新年过分运动神经，同时还可以促进血液循环，治疗各种疼痛，在临床上表现良好。由于脉冲电符合人体生理对刺激的要求，各主要输出参数能根据需要调节现已经被广泛使用，其具有多种功能，能产生多种波形脉冲电，疗效明显，体积小，操作简便安全，省电等优点。
本系统就是基于低频，高压，脉冲等特性设计的一种新型治疗仪，采用新型单片机、程序控制和升压斩波放大，产生变化有序的多种治疗脉冲波形模拟针灸治疗。本系统设计的电脉冲刺激器治疗仪可以用作减轻疼痛、放松肌肉、预防和减缓肌肉萎缩、增加局部血液循环使用。
单片机作为优秀的低端控制器其高效可靠的特性已应用在许多场所，单片机具有集成度高，运算快速快，体积小、运行可靠，价值低廉，在过程控制、数据采集、机电一体化、智能化仪表、家用电器以及网络技术等方面得到广泛应用。本系统主要介绍以STC单片机为主的低频脉冲治疗仪的研究。

Abstract
As technology advances, people in pain mechanism also master more, low-frequency high-voltage therapy, can both excited and nervous, new feeling too motor nerve, also can promote the blood circulation, cure all kinds of pain, in clinical performance is good. Because the pulses to stimulation electric works with human physiology of requirement, each main output parameters can ? ? according to need adjustment now has been used extensively, its has a variety of functions, can produce various waveform pulse electricity, efficacy is obvious, small volume, convenient operation safety, save electricity, etc.
This system is based on low frequency characteristics, high pressure, pulse a new instrument design, adopting new SCM, process control and boost the chopper amplifier, produce change orderly various treatment pulse simulation acupuncture treatment. This system design of electrical impulses stimulator instrument can be used to relieve pain, muscle relaxation, prevent and ease muscle atrophy, increase local blood circulation.
Single chip microcomputer as excellent low-end controller its high efficient and reliable characteristic has been used in many locations, SCM has high, operation quick quick integration, small volume, reliable operation, low, in process control value, data acquisition, mechatronics, intelligent instrumentation, household appliances and network technology, etc widely used. This system mainly introduces microcontroller primarily by STC low frequency impulse of therapeutic.
Key word: microcontroller, low frequency instrument, pulse happen
