Pittsburgh Speed Switch



There are two types of encoding methods commonly used for radio remote control: fixed code and rolling code. The rolling code is a product of upgrading fixed code. At present, wherever there are confidentiality requirements, rolling coding is used.
The rolling code encoding method has the following advantages:
1. The security type is strong, and the code is automatically replaced after each launch. Others cannot use the “code detector” to obtain the address code.
2. The coding capacity is large, the number of address codes is greater than 100,000, and the probability of “re-coding” in use is extremely small;
3, easy to code, rolling code has a learning storage function, without the use of soldering iron, can be coded on the user site, and a receiver can learn up to 14 different transmitters, with a high degree of flexibility in use;
4, the error is small, due to the advantages of the code, so that the receiver does not receive a native code when the malfunction is almost zero.
The coding capacity of the fixed code is only 6561, and the probability of re-encoding is very large. The code value can be seen through the solder joint connection method, or it can be obtained by using the “code detector” at the site of use, so it has no confidentiality and is mainly used. In cases where the confidentiality requirement is low, a large number of applications have also been obtained because of its low price.
The difference between IR remote control and radio remote control, infrared remote control and wireless remote control are for different carriers. Infrared remote control uses infrared to transmit control signals. Its characteristics are: Directional, can not block, distance is generally not more than 7 meters, is not subject to electromagnetic interference, TV remote control is infrared remote control; radio remote control is to use radio waves to transmit control signals, which is characterized by non-directional, It can be controlled not "face to face", far away (up to several tens of meters or even several kilometers), and susceptible to electromagnetic interference. In areas that require long-distance penetration or non-directional control, such as industrial control, etc., using a radio remote controller is easier to solve.
