Embodiment Construction

[0011] Below the present invention is further described:

[0012] The remote car unlocking method provided by the present invention is as follows: install signal processing software on the mobile phone near the spare key, which can continuously tune the resonant frequency of the mobile phone resonator, press and hold the unlock key continuously, and then make the signal processing software control the resonator Carry out continuous search in the characteristic frequency band, after a round of cycles, determine the frequency corresponding to the moment when the received signal is the strongest, determine this as the control signal frequency, and then make the frequency of the resonator consistent with the frequency of the control signal sent by the spare key Use the mobile phone near the spare key to dial and connect the mobile phone of the car owner near the car. At this time, through the signal processing software, the control signal, namely the unlocking signal, is modulated ...

Abstract

The invention provides a long-distance unlocking method for automobiles. Characteristics are that, the frequency of a mobile phone near a spare key is adjusted, so that the frequency of the resonator of the mobile phone is identical with the frequency of a control signal emitted by the spare key; the unlocking button of the spare key is manipulated, an unlocking signal is received by the mobile phone near the spare key through the resonator, and at the same time, a mobile phone of an automobile owner who is near the automobile is dialled and got through, the unlocking signal is superposed on a communication signal after modulation, and both the unlocking signal and the communication signal are send to the mobile phone of the owner near the automobile by communication base stations; and then the unlocking signal is emitted by an emitter after smoothing and demodulation by the mobile phone of the automobile owner, so as to realize unlocking of the automobile. The long-distance unlocking method is capable of unlocking automobiles under conditions that an automobile key is lost by the automobile owner.

Description

[0001] technical field [0002] The invention relates to the communication field, in particular to an automobile unlocking method combining electronic equipment and a wireless communication network. [0003] Background technique [0004] At present, private cars are very popular, so car keys have become a must-have item for many people. However, due to the fast pace of life, there are many cases of forgetting or losing car keys; the current solution can only It is to go home to get a spare key, which obviously wastes a lot of time and energy, and is extremely inconvenient for private car owners. [0005] Contents of the invention [0006] In view of the above problems, the object of the present invention is to provide a remote car unlocking method, which can unlock the car when the car owner loses the car key. [0007] The technical scheme adopted by the present invention to solve its technical problems is: frequency modulation is carried out to the mobile phone near th...
