快卷簾(lian)(lian)門相信很多(duo)人都見(jian)過，車(che)庫或者小商(shang)店門面(mian)裝(zhuang)修(xiu)中大部(bu)分都會使用(yong)到。在以前(qian)的(de)時(shi)候，卷簾(lian)(lian)門一般是用(yong)鑰匙打開，手動使用(yong)，但是現在有(you)了(le)遙控卷簾(lian)(lian)門，使用(yong)起來更加方便(bian)了(le)，但是其使用(yong)問題也有(you)很多(duo)。

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(juan)簾(lian)門(men)遙控距離的影響因素如(ru)下：

The factors affecting the remote control distance of fast rolling shutter doors are as follows:

接(jie)收靈敏度(du)(du)：快速門(men)的接(jie)收器接(jie)收靈敏度(du)(du)提高，能夠(gou)使得遙(yao)控距離增大(da)，但(dan)可能會受干擾造成失控或誤動。

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.

發射功(gong)(gong)率：發射功(gong)(gong)率功(gong)(gong)能大(da)則距離較遠，但確(que)定是(shi)消耗電多(duo)且易(yi)產生受到干擾。

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(du)因素(su)：天線越高，遙控距離越遠，但受客觀條件影響限制。

Height factor: The higher the antenna, the farther the remote control distance, but it is limited by objective conditions.

天線因素：相互平行直(zhi)(zhi)線型天線，遙控(kong)距(ju)(ju)離較遠，但(dan)占據空間大，在使用中把天線拉長、拉直(zhi)(zhi)可增(zeng)加(jia)遙控(kong)距(ju)(ju)離。

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(zu)礙(ai)物阻(zu)擋(dang)(dang)：使用UHF頻段的(de)無線遙控(kong)(kong)器(qi)，其(qi)傳播(bo)特性和光(guang)相似，直(zhi)線傳播(bo)，繞射較小(xiao)，發射器(qi)和接收器(qi)之(zhi)間如有墻壁(bi)(bi)會(hui)阻(zu)擋(dang)(dang)遙控(kong)(kong)距離，有時(shi)候(hou)鋼筋(jin)混泥(ni)土的(de)墻壁(bi)(bi)，由于導體對(dui)電波的(de)吸收作用，可(ke)能會(hui)受到(dao)影響。

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.
