车库门遥控受距离影响的几点因素!

遥控车库门遥控受距离影响的几点因素!
Remote garage door remote control by the distance of several factors!
1、高度:天线越高,遥控距离越远,但受客观条件限制;
1. Height: the higher the antenna is, the farther the remote control distance is, but it is limited by objective conditions;
2、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;
2. Antenna: the linear antenna is used and parallel to each other. The remote control distance is long, but it takes up a large space. In use, lengthening and straightening the antenna can increase the remote control distance;
3、发射功率:发射功率大则距离远,但耗电大,容易产生干扰;
3. Transmitting power: large transmitting power leads to long distance, but it consumes a lot of power and is easy to cause interference;

4、阻挡:目前使用的无线遥控器使用国家规定的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,影响更甚;
4. Blocking: the current wireless remote control uses the UHF frequency band specified by the state. Its propagation characteristics are similar to that of light, with linear propagation and small diffraction. If there is a wall blocking between the transmitter and receiver, the remote control distance will be greatly reduced. If it is a reinforced concrete wall, the influence is more serious due to the absorption of the conductor to the radio wave;
5、接收灵敏度:接收器的接收灵敏度提高,遥控距离加大,但容易受干扰造成误动或失控。
5. Receiving sensitivity: the receiving sensitivity of the receiver is improved, and the remote control distance is increased, but it is easy to be interfered to cause misoperation or out of control.
