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局部血液循环镇痛作用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；SMC1602A 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 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.
