Intelligent lock system based on high-frequency antenna feature judgment

Abstract

The invention relates to an intelligent lock system based on high-frequency antenna feature judgment, which intelligent a lock base station and an intelligent key, wherein the intelligent lock base station is installed on a door; the intelligent lock base station comprises a base station main control module, a trigger module, a low-frequency transmission module, a low-frequency transmission antenna, a high-frequency receiving module, a high-frequency receiving antenna and a motor drive module; the intelligent key comprises a key main control module, a low-frequency receiving module, a low-frequency receiving antenna, a high-frequency transmission module and a high-frequency transmission antenna; the high-frequency receiving antenna is a hemispherical radiating antenna which is used for receiving signals outside the door and inhibiting signals inside the door; and the radiation range of the high-frequency receiving antenna is outside the door. The system can effectively distinguish whether the key is inside the door or outside the door, and has high safety.

Description

technical field [0001] The invention relates to an intelligent lock system, especially an intelligent electronic lock. Background technique [0002] PKE is the abbreviation of Passive keyless entry in English, and it is generally translated into passive keyless entry system in Chinese. The original intention of this technical design is to enable users to carry an electronic key with them, and they can enter the target system without pressing it. Different from RKE's one-way communication, PKE applies the principle of two-way communication, and uses radio frequency signals to verify the identity of the electronic key to improve security. [0003] The working process of the traditional PKE smart lock is: [0004] 1. Wake-up: When the user carries the smart key and appears within the detection range of the smart lock base station, the smart lock base station sends out a low-frequency signal. If this signal matches the wake-up data stored in the smart key, the key will be woke...

AI Technical Summary

Problems solved by technology

[0016] In order to overcome the shortcomings of existing smart lock systems that cannot effectively distinguish whether the key is located inside or outside the door and have poor security, the present invention provides a high-frequency antenna-based lock that can effectively distinguish whether the key is located inside or outside the door and has good security. Intelligent lock system based on feature discrimination
