電動卷簾門遠距離操作故障原因

濟南電動卷簾門操作端有三個按鈕,卷簾門分別接著一根線,還有一條公共線,將開門按鈕的這條線和公共線接到門禁控製器的繼電器控製端的 NO和COM即可。這樣就可以通過刷卡控製打開自動門了。一般情況,電動門有三個功能按鈕,即開門,暫停,關門。下麵由濟南電動卷簾門廠家的小編為大家介紹一下電動卷簾門遠距離操作故障原因有哪些?
Ji'nan electric door operation terminal has three buttons, shutter doors respectively and one line, and a public line, this line will relay control button to open the door and the public line to access controller end NO and COM. This allows you to open the automatic door with swipe control. In general, the electric door has three function buttons, that is, open the door, pause, close the door. The following by the Ji'nan electric rolling shutter door manufacturers Xiaobian for you to introduce the electric rolling shutter door, remote operation failure, what are the reasons?
1、發射功率:發射功率大則距離遠,但耗電大,容易產生幹擾
1, transmit power: transmit power is large, distance, but the power consumption is large, prone to interference

2 、 receiver sensitivity: receiver sensitivity increased, remote control increased, but easily disturbed, causing misoperation or uncontrolled
3、天線:采用直線型天線,並且相互平行,遙控距離遠,但占據空間大,在使用中把天線拉長、拉直可增加遙控距離
3: Antenna: using linear antennas, and parallel to each other, remote control distance, but occupy large space, in use, the antenna elongated and straightened, you can increase the remote control distance
4、高度:天線越高,遙控距離越遠,但受客觀條件限製
4 height: the higher the antenna, the farther away the remote control, but limited by the objective conditions
5、阻擋:目前使用的無線遙控器使用規定的UHF頻段,其傳播特性和光近似,直線傳播,繞射較小,發射器和接收器之間如有牆壁阻擋將大大打折遙控距離,如果是鋼筋混泥土的牆壁,由於導體對電波的吸收作用。
5, stop: wireless remote control the use of the provisions of the state UHF band, its propagation characteristics and optical approximation, linear propagation, diffraction is small, such as walls will be greatly discounted remote distance between the transmitter and the receiver, if the reinforced concrete walls, due to absorption of wave conductor.
