电动门一般都是有遥控器的，并且对电动门可以进行一定距离的遥控，下面我们看一下电动门遥控器对电动门的控制原理。

Electric doors are generally remote control, and the electric door can be a certain distance of remote control, we look at the electric door remote control of the electric door principle.

电动门遥控器是利用无线电信号对远方的种种机构举行控制的遥控配置。信号被远方的汲取配置汲取后，可以指令或驱动别的种种相应的呆板大概电子配置，去完成种种操作，如闭合电路、移动手柄、开动电机，之后再由这些呆板举行必要的操作。作为一种与红外遥控器相增补的遥控器种类，在车库门、电动门、道闸遥控控制，防盗报警器，工业控制以及无线智能家居范畴得到了普遍的应用。

Electric door remote control is the use of radio signals to remote control of various institutions remote control configuration. The signal is drawn away from post configuration, can drive the corresponding instruction or other kinds of rigid about the electronic configuration, to complete various operations, such as closed circuit, moving the handle, the motor is started, followed by these machines held necessary operation. As a kind of remote control device added with infrared remote control, it has been widely used in garage door, electric door, gate remote control, burglar alarm, industrial control and wireless intelligent home.

常用的电动门遥控体系一样平常分发射和汲取两个部门。发射部门一样平常分为两种范例，即遥控器与发射模块，遥控器和遥控模块是对付利用要领来说的，遥控器可以当一个整机来独立利用，对外引出线有接线桩头；而遥控模块在电路中当一个元件来利用，根据其引脚定义举行应用，利用遥控模块的优势在于可以和应用电路天衣无缝的连接、体积小、代价低、物尽其用，但利用者必须真正明白电路原理，否则还是用遥控器来的方便。汲取部门一样平常来说也分为两种范例，即超外差与超再生汲取要领，超再生解调电路也称超再生检波电路，它实际上是事情在间歇振荡状态下的再生检波电路。超外差式解调电路与超外差收音机雷同，它是设置一本机振荡电路孕育产生振荡信号，与汲取到的载频信号混频后，得到中频信号，经中频放大和检波，解调出数据信号。

Commonly used electric door remote control system, as usual, transmit and draw two departments. The launch department generally divided into two types, namely, remote control and transmission module, remote control and remote control module is used to deal with and say, the remote control can be a machine independent use, external outgoing line pile head connection; and the remote control module in the circuit when a device to use, according to the definition the pin held by the remote control module of the application, advantage and application of the circuit can be connected, a seamless heavenly robe of small volume, low cost, but its use must truly understand the principle of the circuit, or to use a remote control to facilitate. Learn the Department in general is divided into two types, namely super heterodyne and super regenerative absorbing essentials, super regenerative demodulation circuit is also called super regenerative detection circuit, it is actually that regenerative detection circuit in the intermittent oscillation condition. Super heterodyne demodulation circuit is identical with the superheterodyne, it is provided with a local oscillation circuit generates an oscillation signal, mixed with the carrier frequency signal received after the frequency signal, the intermediate frequency amplification and detection, demodulation of the data signal.
