1、摘要盆腔炎治疗仪,利用物理的电、热、磁等生理作用,促进人体神经肌肉组织兴奋和局部血液循环,并有镇痛作用。盆腔治疗仪对盆腔炎的治疗,具有无副作用和后遗症等优点,在妇科中得到广泛的应用。因为在治疗过程中需要调整治疗参数,为方便患者自己根据治疗需要适时调整,设计具有无线遥控功能键盘能为患者使用带来极大的方便。本文正是为解决此问题,提出了盆腔炎治疗仪遥控系统的解决方案。无线遥控包括发射和接收两部分。发射部分包括发射电路、编码芯片、键盘电路和电源电路。接受部分,包括射频接受电路、解码芯片PT2272、起控制作用的单
2、片机AT89S52和起交互作用的显示屏SMC1602A。发射电路,采用特低功耗超再生原理,工作频率315MHz,433MHz,工作电压DC+3V,调制带宽10K。编码芯片采用PT2262,具有4路或6路数据输入,串行编码输出,最多可以发送63个控制指令。关键字:盆腔治疗仪;无线遥控;PT2262;PT2272;单片机AT89S52;SMC1602A1AbstractTheinstrumentforpelvicinflammationtreatment,usesphysiologicalactionsoft
