快速卷帘门�？鼐嗬氲挠跋煲蛩�!
快卷帘门相信许多人都见过，车库或者小商店门面装修中大部分都会使用到。在以前的时候，卷帘门一般是用钥匙翻开，手动使用，可是现在有了�？鼐砹泵�，使用起来越发便当了，可是其使用问题也有许多。
I believe many people have seen fast rolling shutter doors, which are commonly used in garage or small store decoration. In the past, roller shutter doors were usually opened manually with a key, but now with remote control roller shutter doors, it is more convenient to use, but there are also many usage problems.
快速卷帘门�？鼐嗬氲挠跋煲蛩厝缦拢�
The factors affecting the remote control distance of fast rolling shutter doors are as follows:
接收灵敏度：快速门的接收器接收灵敏度提高，能够使得�？鼐嗬朐龃�，但可能会受滋扰造成失控或误动。
Receiving sensitivity: The receiver of the fast gate has improved receiving sensitivity, which can increase the remote control distance, but may be affected by interference and cause loss of control or misoperation.
发射功率：发射功率功效大则距离较远，但确定是消耗电多且易爆发受到滋扰。
Transmission power: If the transmission power function is large, the distance is relatively long, but it is determined that it consumes a lot of electricity and is prone to interference.
高度因素：天线越高，�？鼐嗬朐皆�，但受客观条件影响限制。
Height factor: The higher the antenna, the farther the remote control distance, but it is limited by objective conditions.
天线因素：相互平行直线型天线，�？鼐嗬虢显�，但占据空间大，在使用中把天线拉长、拉直可增加�？鼐嗬�。
Antenna factor: Parallel linear antennas have a long remote control distance but occupy a large space. Lengthening and straightening the antennas during use can increase the remote control distance.
阻碍物阻挡：使用UHF频段的无线�？仄�，其流传特性和光相似，直线流传，绕射较小，发射器和接收器之间如有墙壁会阻挡�？鼐嗬�，有时候钢筋混泥土的墙壁，由于导体对电波的吸收作用，可能会受到影响。
Obstacle obstruction: Wireless remote controllers in the UHF frequency band have propagation characteristics similar to light, with linear propagation and less diffraction. If there is a wall between the transmitter and receiver, it will block the remote control distance. Sometimes, reinforced concrete walls may be affected due to the absorption of radio waves by the conductor.
