Influencing factors of remote control distance of automatic door remote control and matching method thereof

The?automatic door remote control is a remote control device that remotely controls various remote devices using radio signals. As a kind of remote control supplemented with infrared remote control, electric door remote control has been widely used in garage door, electric door, gate remote control, burglar alarm, industrial control and wireless smart home. The following gives you a detailed explanation of the influencing factors and matching methods of the remote control distance of the?automatic?door remote control.

The main factors affecting the remote distance of?automatic?door remote control are as follows:

1. Transmitting power: If the transmitting power is large, the distance is long, but the power consumption is large, and it is easy to cause interference;

2. Receiving sensitivity: the receiver’s receiving sensitivity is increased, the automatic door remote control distance is increased, but it is easy to be disturbed or out of control;

3. Antenna: the use of linear antennas, and parallel to each other, remote control distance is far, but occupy a large space, in the use of the antenna to lengthen, straighten can increase the remote control distance;

4. Height: the higher the antenna, the farther the remote control distance, but subject to objective conditions;

5. Blocking: The wireless remote control uses the UHF frequency band specified by the state, its propagation characteristics and light approximation, straight line propagation, and small diffraction. If there is wall blocking between the transmitter and the receiver, the remote control distance will be greatly discounted. If it is reinforced concrete The wall is more affected by the absorption of electric waves by the conductor.

Fixed code?automatic door remote control matching method

With the appearance of the copy remote control, make the matching of the?automatic?door remote control very simple,and the matching of the fixed code remote controller can be quickly completed in two steps.

(1) Features do not need a copy machine, do not need to know the oscillating resistance, directly use the remote control to copy the remote control, can be used immediately.

(2) Prerequisites for using this remote control.

①The original remote control can be used, and it can be controlled normally.

② Need to know the frequency of the remote control (such as 390MHz, 400MHZ, etc.).

③The remote control chip is the following copyable chip:

SC2260/SC2262/HS2260/HS2262/PT2262/PT2260/EV15271SCL1527/SC5211/FP527/PT2240

/HS2260/SC2240/HS1527/CL2262/HS2240/PT2264/LX2260/X2262/LP8527/HX2262/HX2260(Most fixed code and partial learning code remote control are compatible on the market).

(3) Specific methods of operation.

① clear code. At the same time, press the two buttons on the upper row of the remote control, the “open door” button and the “close door” button. After the indicator flashes once, flashing for about 2 seconds means that the clearing is successful. After clearing, press the 4 button of the remote control to flash only once and then go out.

② pairs of copies. One hand holds the original remote control, the other hand holds the universal copy remote control, the two remote controls are as close as possible, and at the same time press the two remote control “open the door” button, copying the remote control indicator light flashes quickly, indicating that the copy is successful. Then release your hand. In the same way, copy the other three buttons.

Note: If the light does not flash when copying, you can change the position. For example, try to copy the heads of the two electric retractable door remotes. You can try several more positions.

③recovery. If the useful code is cleared by mistake, you can press the two buttons on the lower row of the remote control for 2 seconds at the same time without recopying the other remote controllers. After the indicator flashes quickly, the recovery is successful.

The above is about the influencing factors of the remote control distance of the?automatic door remote control and its matching method.
