Embodiment Construction

[0035] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0036] Such as figure 1 As shown, an anti-theft system for a vehicle includes: an anti-theft terminal 10 for sending out a low-frequency induction signal to detect the induction key 20; an induction key 20 for sending out a High frequency authentication signal;

[0037] The induction enhancement device 30 is used to detect the high-frequency authentication signal sent by the induction key 20 when the low-frequency induction signal of the anti-theft terminal is detected, and send a low-frequency induction signal if the high-frequency authentication signal is not detected, And the induction detection of the induction key 20 is carried out through the low-frequency induction signal sent by the induction enhancement device 30 .

[0038] In this embodiment ...

Abstract

The invention provides a vehicle anti-theft system and an induction intensifying device and method. The vehicle anti-theft system comprises an anti-theft terminal, an induction key and the induction intensifying device, wherein the anti-theft terminal is used for giving out a low-frequency induction signal to detect the induction key, the induction key is used for giving out a high-frequency authentication signal after receiving the low-frequency induction signal given out by the anti-theft terminal, the induction intensifying device is used for detecting the high-frequency authentication signal given out by the induction key after the low-frequency induction signal given out by the anti-theft terminal is detected, and is used for giving out a low-frequency induction signal when the high-frequency authentication signal is not detected, and induction detection is carried out on the induction key through the low-frequency induction signal given out by the induction intensifying device. According to the scheme, communication effectiveness of the self-induction anti-theft system can be effectively improved, and wide application of the self-induction anti-theft system is promoted.

Description

technical field [0001] The invention relates to the technical field of automobile information services, in particular to a vehicle anti-theft system, an induction enhancement device and a method. Background technique [0002] The existing self-induction vehicle anti-theft device is composed of an anti-theft terminal placed in the car and a portable induction key. When the owner gets on the car and starts the vehicle, the anti-theft terminal will take the initiative to sense the owner's sensor key, and if the detection is successful, it will automatically disarm, and if the sensor key is not detected, it will trigger an alarm and other operations; when the owner parks and leaves, the anti-theft terminal will automatically enter to the defense state. [0003] Among them, the induction detection of the induction key is a key technology in the self-induction anti-theft device. At present, this kind of anti-theft device uses 125KHz low-frequency signal to detect the induction k...
