The main failure factors of remote control operation of electric rolling shutter door are as follows:

　　1.发射功率:发射功率大，距离远，但耗电大，容易产生干扰;

　　1. Transmitting power: high transmitting power, long distance, but high power consumption, easy to produce interference;

　　2.接收灵敏度:提高了接收机的接收灵敏度，增加了遥控距离，但容易受到干扰，造成误操作或失去控制;

　　2. Receiving sensitivity: improve the receiving sensitivity of the receiver, increase the remote control distance, but it is easy to be interfered, resulting in misoperation or loss of control;

　　3.天线:采用直线天线，且彼此平行，遥控距离虽远，但占用空间大，在使用时天线拉长，直线可增加遥控距离;

　　3. Antenna: the linear antenna is used, which is parallel to each other. Although the remote control distance is far, it takes up a large space. When the antenna is extended, the linear antenna 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 the remote control distance, but limited by objective conditions;

　　5.目前用于无线遥控使用超高频频段规定的,其传播特性和光近似线性传播,衍射很小,如果有一个发射器和接收器之间的墙块将大大折扣遥控距离,如果是钢筋混凝土墙,由于吸收的指挥海浪的影响,更影响。

　　5. At present, the UHF band is used for wireless remote control according to the national regulations. Its propagation characteristics and light are nearly linear propagation, and its diffraction is very small. If there is a wall block between transmitter and receiver, the remote control distance will be greatly reduced. If it is a reinforced concrete wall, it will be more affected due to the influence of the absorbed command wave.
