Sometimes, for some reason, we can operate the crystal roller door at a long distance, but one operation fails. So, what is the reason for the failure of remote operation of rolling gate? Let´s listen to Haifeng door industry´s explanation of this problem.In fact, the main reasons for the failure of remote operation of the crystal shutter door are as follows:1. Height: the higher the antenna is, the farther the remote control distance is, but it is limited by objective conditions;2. Transmitting power: the transmitting power of the remote control instrument is large, but the distance is long, but the power consumption is large, and it is easy to produce interference;3. Receiving sensitivity: it improves the receiving sensitivity of the remote control receiver and increases the distance of the remote control, but it is easy to interfere with the receiving sensitivity, resulting in misoperation or out of control;4. Antenna: if a linear antenna is used and they are parallel to each other, the remote control distance can be longer, but it will occupy a larger space, and the remote control distance can be increased by lengthening and straightening the antenna;5. Blocking: the current wireless remote control uses the UHF frequency band specified by the state. Its propagation characteristic is similar to that of light, which is straight-line propagation and small diffraction. If there is a wall between the transmitter and the receiver, the remote control distance will be greatly shortened. If it is reinforced concrete wall, its influence will be more serious due to the absorption of electromagnetic wave by guide. So if we choose this type of remote control instrument, the possibility of failure will increase with the increase of distance.When there is a remote operation failure of our crystal door, it is precisely because of the above reasons that we can reduce the remote operation to avoid such failure.Crystal shutter door chooses Haifeng door industry.
