| 伸缩门遥控器与红外遥控器的区别，红外遥控和无线遥控是对不同的载波来说的，红外遥控器是用红外线来传送控制信号的，它的特点是有方向性、不能有阻挡、距离一般不超过7米、不受电磁干扰，电视机遥控器就是红外遥控器；自动门遥控器是用无线电波来传送控制信号的，它的特点是无方向性、可以不“面对面”控制、距离远（可达数十米，甚至数公里）、容易受电磁干扰。在需要远距离穿透或者无方向性控制领域，比如工业控制等等，使用自动门遥控器较易解决。 The difference between the retractable door remote control and the infrared remote control is that the infrared remote control and the wireless remote control are for different carriers. The infrared remote control uses the infrared to transmit the control signal. Its characteristics are directionality, no blocking, the distance is generally no more than 7 meters, and no electromagnetic interference. The TV remote control is the infrared remote control; the automatic door remote control uses the radio wave to transmit For the control signal, it is characterized by no direction, no "face-to-face" control, long distance (up to tens of meters, even several kilometers), and easy to be interfered by electromagnetic interference. In the field of long-distance penetration or non directional control, such as industrial control, it is easy to use automatic door remote control. |
