Description

technical field [0001] It belongs to the field of electronic technology. Background technique [0002] Remote control code transmission technology, one is a very widely used electronic technology, which appears widely in the lives of the masses. As we all know, anti-copying, anti-interference, and high security level are important technical indicators that indicate the pros and cons of remote control code transmission technology. Judging from the current technical level, if the car's central control lock is put into the remote control, it is not safe enough to operate. When criminals use a car remote control jammer with sufficient power nearby, it can interfere and intercept the signal of the car remote control, so that other out of order. Since the jammer is not limited by the types of vehicles and remote controls when it is used, fixed codes, special codes, and rolling codes can interfere. As long as the interference power is large enough, any model can interfere, so that...
