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；SMC1602AAbstractTheinstrumentforpelvicinflammationtreatment,usesphysiologicalactionsofthephysicalelectricity,heat,magnetismfortherapy,hasthepromotionofexcitednervemusculartissue,thepartialbloodcirculationandeasesthepain，withmeritofnosideeffectandsequela.Soitobtainsthewidespreadapplicationinthegynecologydepartment。Becauseinthecourseoftreatmentthepatientneedstoadjustthetreatmentparameter,thedesigningwiththewirelessremotecontrolfunctionkeyboardbringingenormousconvenienttothepatient.Thisarticleispreciselyforsolvesthisproblem,proposedthepelviccavitytreatmentmeterremotecontrolmodulesolution.Thewirelessremotecontrollerincludinglaunchedpartandreceivedpart.Thelaunchedpartsincludingtransmissioncircuit,codechip,keyboardcircuitandpowercircuit.Thereceivedmodule,includethereceivedcircuit,decodingchipPT2272,controllerAT89S52andthecorrelationdisplaymonitorSMC1602A.Thetransmissioncircuit,usestheespeciallylowpowerlossultraregenerationprinciple,operatingfrequency315MHz,433MHz,workingvoltageDC+3V,modulationband-width10K.ThecodechipusesPT2262,has4groupor6groupdatafeedsandtheserialcodeoutput,mostmaytransmit63controlcommands.Keywordsinstrumentforpelvicinflammationtreatment；wirelessremotecontroller；PT2262；PT2272；AT89S52；SMC1602A目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc200426238"第1章绪论PAGEREF_Toc200426238\h6HYPERLINK\l"_Toc200426239"1.1课题背景PAGEREF_Toc200426239\h6HYPERLINK\l"_Toc200426240"1.2遥控器原理PAGEREF_Toc200426240\h6HYPERLINK\l"_Toc200426241"1.3设计任务PAGEREF_Toc200426241\h6HYPERLINK\l"_Toc200426242"1.4设计的意义
