卷帘门遥控器系统，一般卷帘门遥控器系统分为发射和接收两个部分，发射部分一般分为两类，即遥控器与发射模块，就使用方式而言，遥控器可作为一台整机，对外引出线有接线桩头。
而且遥控器模块就像电路中的一个元件一样，济南卷帘门按照它的引脚定义应用。接收器也可以分为两种类型，即超外差和超再生接收方式，超再生电路又称为超再生检波电路，它是工作于间歇振荡状态的再生检波电路。

对于门遥控器的接收部分，可分为超外差和超再生两种方式。超再生检波电路又称超再生检波电路，实际上就是间歇振荡状态下的再生检波电路。与超外差式解调电路类似于超外差无线电，它是将一本机振荡电路产生振荡信号，与接收到的载频信号混频后，得到的中频信号经中频放大和检波，再解调出数据信号。对于卷帘门遥控器的配置也经常采用这两种方法。
For the receiving part of the door remote control, it can be divided into superheterodyne and superregeneration. Super-regenerative detection circuit is also called super-regenerative detection circuit, in fact, it is a regenerative detection circuit under intermittent oscillation state. The superheterodyne demodulation circuit is similar to the superheterodyne radio, it is a local oscillator circuit to produce an oscillation signal, and received carrier frequency signal mixed, the intermediate frequency signal by intermediate frequency amplification and detection, and then demodulation out of data signals. These two methods are often used for the configuration of the shutter door remote control.

超外差式解调电路与超外差无线电相同，它是将一本机振荡电路产生振荡信号，与接收到的载频信号混频后，得到中频放大和检波后的中频信号(一般为465 kHz)，解调数据信号。
The superheterodyne demodulation circuit is the same as the superheterodyne radio. It is the same as the superheterodyne radio. The superheterodyne demodulation circuit produces an oscillating signal. After mixing the received carrier Frequency Signal, the intermediate frequency signal is amplified and detected (generally 465 Khz) , demodulation data signal.

根据遥控器的配置，可分为红外遥控器和无线遥控器，这两种遥控器由于不同的载波类型，采用红外线传输控制信号，其特点是具有方向性，中间不能有阻挡，距离一般不会超过7米，同时不会受到电磁干扰，电视遥控器采用的是红外遥控器。
无线遥控器是利用无线电波传输控制信号的一种，济南卷帘门遥控器其特点是具有无方向性，中间遮挡物也可进行控制，控制距离远，但易受电磁干扰。当需要远距离探测时实用。
