Embodiment
[0033] The pins of the main control module 11 are connected to the trigger module 12 . The function of the trigger module is to sense the external trigger of the smart lock system, and wake up the main control module in the low power consumption state to enter the working state. There are many implementation examples of the trigger module: 1. The method of mechanical buttons is adopted. When the user presses the button, the level signal is transmitted to the main control module 11, and the pin of the main control module generates an interrupt to wake up the system; 2. The method of touching the button , by sensing the capacitance generated by the user's body or hand and the touch keyboard, the system is interrupted; 3. The system is interrupted when the user's body or hand is close by the proximity sensing method; 4. The system is interrupted by infrared sensing .

The invention relates to a passive smart lock system based on limited interaction. The passive smart lock system based on limited interaction comprises a smart lock base station and a smart key, wherein the smart lock base station is arranged on a door and comprises a base station master control module, a trigger module, a low-frequency transmitting module and a low-frequency transmitting antenna, a high-frequency receiving module, a high-frequency receiving antenna, a motor driving module and an auxiliary signal transmitting module, the smart key comprises a key master control module, a low-frequency receiving module, a low-frequency receiving antenna, a high-frequency transmitting module and a transmitting antenna, the transmitting direction and the transmitting zone of the auxiliary signal transmitting module is outside a door, the smart key also comprises an auxiliary signal receiving module used for monitoring whether the current zone has an auxiliary signal and an auxiliary condition judgment module for judging the current key position and selectively judging whether to meet the current ID transmitting condition according to a condition whether the auxiliary signal exists, and the auxiliary condition judgment module is connected with the key master control module. The passive smart lock system based on limited interaction can effectively distinguish whether the key is positioned inside the door or outside the door, and has good 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...
