Now we are demanding more and more things. When we choose the rolling door, many people tend to be electric. The electric roller shutter has a drawback, that is, how to do it when the remote control is lost. In order to avoid this problem, we need to be prepared in advance. Everyone knows how to match the roller shutter remote control? Today, Xiaobian will take a look at how the shutter door remote control is equipped with the shutter door remote control operation method!
How to match the rolling door remote control
1. Composition
I believe that everyone will encounter the same problem when using the rolling door, which is how to match the rolling door remote control. Commonly used rolling door remote controls are generally divided into two parts: transmitting and receiving.
2, the way
As far as the receiving part of the rolling door remote control is concerned, it can be divided into super heterodyne and super regenerative. The super-regenerative demodulation circuit is also called a super-regenerative detection circuit, and is actually a regenerative detection circuit in an intermittent oscillation state.
3, wave frequency
The carrier frequency commonly used in the remote control configuration of the rolling door is 433mHz and 315mHz. The carrier frequency used by the remote control is the nationally prescribed open frequency band. In this frequency band, the transmitting power is less than 10mW and the coverage is less than 100m, as long as it does not exceed the unit range. They are free to use without having to go through the "Radio Management Committee" approval.
4, classification
In the configuration of the shutter remote control, it can be divided into an infrared remote controller and a wireless remote controller. They are due to different carriers. The infrared remote controller uses infrared rays to transmit control signals. It is characterized by directionality and cannot be in the middle. The blocking and distance are generally no more than 7 meters, and will not be subject to electromagnetic interference. The remote control used in the TV remote control is the infrared remote control.
Operating system with shutter door remote control
1, clear code
At the same time, pressing the two button indicators on the upper row of the remote control flashes once after about 2 seconds, indicating that the clearing is successful. After clearing, press the four buttons of the remote control to flash only once and then go out.
2, copy
Place the original remote control side by side with the remote control remote control (preferably take the quick copy remote control in the right hand), and press any of the two remote control buttons at the same time. If the flashing remote control indicator flashes quickly, the copy is successful. It can be copied successfully in only 1 second. In the same way, copy the other three button pairs.
3, recovery
If the useful code is cleared by mistake, you can press the two buttons on the lower right side of the remote control for 2 seconds before re-copying the other remote controllers.
We all know the importance of the shutter remote control, so we can have a spare in advance. The above is Xiaobian for everyone to see how the remote control of the shutter door is equipped with a remote control. Here is the end, want to know more information, please continue to pay attention to the decoration home network.
