Single-wave dual-code emission designing scheme

Abstract

A single-wave dual-code emission designing scheme belongs to the technical field of electronics and comprises a single-wave dual-code emission designing scheme I and a single-wave dual-code emission designing scheme II. The single-wave dual-code emission designing scheme mainly includes single-wave dual-code power supply resources, a single-wave dual-code button switch, a single-wave dual-code oscillating circuit, a single-wave first-code electronic switch, a single-wave first-code encoding electronic circuit, a single-wave first-code output electronic circuit or a single-wave first-code emission isolation electronic circuit, a single-wave second-code electronic switch, a single-wave second-code encoding electronic circuit, a single-wave second-code output electronic circuit or a single-wave second-code emission isolation electronic circuit, a single-wave dual-code emission electronic circuit or a single-wave first-code emission electronic circuit, and a single-wave dual-code emission electronic circuit. A single-wave dual-code manner is adopted, even through it's a single wave, the carrier wave of the single wave can be flexibly selected between the first carrier wave and the second carrier wave, and the encoding of the two carrier waves is different. The single-wave dual-code emission designing scheme can match a central locking automatic input device for use after all the vehicles doors are closed, so that the automobile security coefficient is effectively increased.

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...

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 the car cannot be locked. command, resulting in the false lock of the vehicle, which is unsafe and causes great hidden dangers

What's more, some criminals can also use a special electronic device called a "code grabber" or "duplicator". When the owner is locking with a remote control, this electronic device can capture the radio frequency signal and password of the remote control signal, after the owner leaves, criminals will use the instrument to boldly copy the password signal to unlock and steal, causing unnecessary economic losses to the owner and causing major safety hazards; the number of automobile products alone is huge. there is a huge market
