无线转红外技术的教学设备的升级改造

Upgrade and improvement of teaching equipment based on wireless transfer infrared technology

因红外线特性只能在视距10m左右内有效,使得多媒体教学设备的红外控制功能受到了极大的限制。采用了能够穿透障碍物的无线收发通信技术,从而避开了红外视距距离短的限制,并且以"自学习"方式解读教学设备的红外编码,完成了无线编码到红外编码的转化,从而实现了教学设备与中控的无缝集成。经实践应用表明,无线转红外技术是教学设备升级改造的有效途径。

The infrared control functions of multimedia teaching equipment have been highly restricted since the valid distance of the infrared properties is only 10 meters. In this study ,the technique of wireless transceiver communication is used ,which could penetrate the barriers. Therefore ,the limitation of short distance for the infrared control can be avoided. Furthermore ,the infrared coding of the teaching equipment can be interpreted by using self-learning mode. So the conversion from wireless coding to infrared coding will be realized and a seamless integration of teaching equipment and middle control can be achieved further. It has been demonstrated practically that technique of the wireless transfer infrared is an effective way for upgrading of the teaching facilities .
