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.
