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。

Abstract
The instrument for pelvic inflammation treatment, uses physiological actions of the physical electricity, heat, magnetism for therapy, has the promotion of excited nerve muscular tissue, the partial blood circulation and eases the pain，with merit of no side effect and sequela. So it obtains the widespread application in the gynecology department。Because in the course of treatment the patient needs to adjust the treatment parameter, the designing with the wireless remote control function keyboard bringing enormous convenient to the patient. This article is precisely for solves this problem, proposed the pelvic cavity treatment meter remote control module solution. The wireless remote controller including launched part and received part. The launched parts including transmission circuit, code chip, keyboard circuit and power circuit. The received module, include the received circuit, decoding chip PT2272, controller AT89S52 and the correlation display monitor SMC1602A. The transmission circuit, uses the especially low power loss ultra regeneration principle, operating frequency 315MHz,433MHz, working voltage DC+3V, modulation band-width 10K.The code chip uses PT2262, has 4 group or 6 group data feeds and the serial code output, most may transmit 63 control commands.
