Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, example 1: the embodiment of the invention provides a non-inductive passing key access control system, which comprises a non-inductive key, an access control card reader and a key card sender, wherein the non-inductive key, the access control card reader and the key card sender are connected in a wireless mode, and the non-inductive key consists of a group of antennas and chips capable of generating low-frequency radio-frequency signals, a group of antennas and chips capable of generating high-frequency radio-frequency signals, a group of chips and batteries for storing user keys and other peripheral supporting circuits.
The non-sensing key adopts STM8L051F3P6TR as a core CPU. The key card sender consists of an STM8S103F single chip microcomputer and peripheral elements thereof. The entrance guard card reader consists of an STM8S105K4T6 singlechip and peripheral elements thereof.
The STM8L051F3P6TR is used AS a key core MCU, starts to work after being awakened by AS3933, and sends own ID to the card reader through 2.4G radio frequency signals, so that the card reader can judge the authority. AS 3933: and receiving a 125KHz signal generated by the card reading device, and then activating and waking up the MCU to start working.
When the key is in a standby state, the low-frequency signal chip of the non-sensing key end is in an active state and keeps sending out a low-frequency detection signal to the outside. Once the low-frequency detection signal is detected by the entrance guard card reader, the entrance guard card reader can return a group of handshake signals. After the handshake signal is identified by the non-sensing key, the chip of the high-frequency radio-frequency signal at the non-sensing key end is activated, and an encrypted user secret key is sent out.
After the user secret key is sent out, the entrance guard card reader collects the user secret key sent out by the unknown key and carries out authority authentication on the key code. If the identification is passed, the electromagnetic lock is driven to open the corresponding door so as to let the user pass.
Example 2: on the basis of the embodiment 1, the non-sensing key further comprises an AS3933 wake-up device and a CC2500 type 2.4G transmission chip. CC 2500: and the system is responsible for 2.4G signal transmission and carries out radio frequency communication with the card reader. When the key is in the 125KHz signal emission range of the card reader, the AS3933 starts to work after being activated, and the MCU communicates with the card reader through 2.4G signals.
