电动卷帘门远距离操作故障原因

发布人:http://www.kdjlm.com    发布时间:2017-06-29 09:36:41

济南电动卷帘门操作端有三个按钮,卷帘门分别接着一根线,还有一条公共线,将开门按钮的这条线和公共线接到门禁控制器的继电器控制端的 NO和COM即可。这样就可以通过刷卡控制打开自动门了。一般情况,电动门有三个功能按钮,即开门,暂停,关门。下面由济南电动卷帘门厂家的小编为大家介绍一下电动卷帘门远距离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、发射功率:发射功率大则距离远,但耗电大,容易产生干扰
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、天线:采用直线型天线,并且相互平行,遥控距离远,但占据空间大,在使用中把天线拉长、拉直可增加遥控距离
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:天线越高,遥控距离越远,但受客观条件限制
4 height: the higher the antenna, the farther away the remote control, but limited by the objective conditions
5、阻挡:目前使用的无线遥控器使用规定的UHF频段,其传播特性和光近似,直线传播,绕射较小,发射器和接收器之间如有墙壁阻挡将大大打折遥控距离,如果是钢筋混泥土的墙壁,由于导体对电波的吸收作用。
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.
