Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0022] As shown in Figure 4, the method for opening the car security device of the present invention includes the following steps: 1. When the vehicle is in the anti-theft state, when the user approaches the vehicle and pulls the door handle or touches the button on the door handle, the security host immediately Search whether there is an active electronic tag for a valid smart card key; 2. If the smart card key works normally, it will be activated immediately and send its serial number back to the security host; if the security host searches for a set time, no smart card key is found If the active electronic tag in the system is detected, or the set trigger signal is detected, it is judged that the active electronic tag is not working normally, and then it will switch to searching for the passive electronic tag. At this time, the user also kno...

Compared with the prior art, the utility model adopts the intelligent card key combining active and passive electronic label; the passive electronic label unlocks vehicles when the traditional intelligent card key cannot work normally without reducing the security performance of the intelligent card key; the utility model has the advantages of low cost and high reliability, and enables to bring various conveniences to customers, and at the same time ensures the personal and property security of the users.

Description

technical field [0001] The invention relates to a method for opening an automobile anti-theft device and its security device, in particular to a method for opening an automobile keyless anti-theft device and its security device. Background technique [0002] In the car anti-theft device, the keyless security device using the radio frequency identification method is composed of two parts: a host installed in the car, also known as a base station or a transceiver; the other is the smart card key carried by the user, which is transponder or electronic tag. The sensing distance of the keyless entry system in the prior art, that is, the recognizable range is between 1.5 and 2 meters, so the smart card key needs to be powered by a battery, that is, the smart card key is an active card. Each smart card key is given a unique code when it leaves the factory. When the legal smart card that enters the sensing distance is recognized by the host, the car lock will automatically open, an...
