At present, smart home is becoming more and more close to our life, such as the use of doors and windows and electrical appliances, and remote control through the remote control, so as to experience high-quality life. The horizontal shutter can work together with the wall. The rolling shutter door is composed of panel, curtain, guide rail, reel, bracket, box, door rolling machine, control box, manual quick release switch and other components. Generally, it is installed in the place where the door opening is relatively large. It can open the door conveniently and quickly where it is not convenient to install the ground door body. At the same time, the configuration of the remote control of the rolling shutter door can make the use of the rolling shutter door more convenient and fast, it is more relaxed than manual. Today, let's talk about how Jinan roller shutter door should be equipped with remote control.

I believe that everyone in the use of Jinan roller shutter door will encounter the same problem, that is, how to match the remote control of rolling shutter door. The commonly used remote control of rolling shutter door is generally divided into two parts: transmitting and receiving. The remote controller can be used as a whole machine, and the transmitting module can be used as a component in the circuit. The remote control module can be connected with the application circuit seamlessly. If you don't know it very well or choose to use the remote control will be more convenient.
In terms of the receiving part of the remote control of rolling shutter door, it can be divided into two ways: superheterodyne and super regeneration. Super regenerative demodulation circuit is also called super regenerative detection circuit, which is in fact a regenerative detection circuit in intermittent oscillation state. The superheterodyne demodulation circuit is similar to the superheterodyne radio. A local oscillation circuit is set to generate the oscillation signal. After mixing with the received carrier frequency signal, the intermediate frequency signal obtained is amplified and detected, and then the data signal is demodulated. In the rolling shutter door remote control configuration also often take these two ways.
The carrier frequency commonly used in the configuration of Jinan rolling shutter door remote controller is 433MHz and 315MHz. The carrier frequency used by the remote control is an open frequency band specified by the state. Within this frequency band, the transmission power is less than 10MW and the coverage is less than 100m. As long as it does not exceed the scope of the unit, it does not need to be approved by the "Radio Management Committee" and can be used freely. The open frequency band is 315MHz, while that of European and American countries is 433MHz. Manufacturers will adjust the production according to different regulations of different countries. Therefore, the frequency of remote controllers exported to different countries is different.

The above is how Jinan roller shutter door equipped with remote control related content, for how to configure the rolling shutter door remote control, there is no unified answer. The remote control of rolling shutter door can be configured according to different needs, which is convenient for us to use. Rolling shutter door is widely used in production enterprises or some workshops. The remote control of rolling shutter door can be reasonably configured according to the distance and whether there are obstacles in the middle. Let's introduce it to you today.
