Problems solved by technology

Due to the way of entering the password through the keyboard, the password needs to be disclosed to all legitimate users, so it is easy to cause the possibility of the password being leaked to illegal users or tampered with, so it is not commonly used; and in the RFID-based unlocking scheme, the password is written into the RFID The card is distributed to legitimate users, and the password is not disclosed to the user, so it can effectively reduce the possibility of the password being leaked or tampered with; however, due to the multi-directionality of the radio frequency signal, the radio frequency signal carrying the password Easy to be stolen, insufficient security

Abstract

An embodiment of the invention discloses an entrance guard system, which comprises a light-emitting diode (LED) door key and an LED light-operated trick lock. The LED door key is used for enabling pre-stored password data to be converted into LED visible light signals which are sent to the LED light-operated trick lock for requesting for unlocking the LED light-operated trick lock. The LED light-operated trick lock is used for receiving the LED visible light signals emitted by the LED door key and enabling the LED visible light signals to be restored to the password data. The LED light-operated trick lock is further used for carrying out unlocking or maintaining current state according to the password data. The embodiment further discloses the LED door key, the LED light-operated trick lock and the entrance guard method. The entrance guard method, the entrance guard system, the LED door key and the LED light-operated trick lock can reduce energy consumption and are favorable to energy conservation.

Description

technical field [0001] The invention relates to access control technology, in particular to an access control method and system, an LED door key and an LED light-controlled combination lock. Background technique [0002] At present, the access control system based on combination locks has been widely used in small and medium-sized enterprises. It provides users with two unlocking schemes, one is to enter the password through the keyboard that comes with the combination lock to unlock; the other is Yes, through the unlocking method of RFID (Radio Frequency Identification, radio frequency identification) technology. Due to the way of entering the password through the keyboard, the password needs to be disclosed to all legitimate users, so it is easy to cause the possibility of the password being leaked to illegal users or tampered with, so it is not commonly used; and in the RFID-based unlocking scheme, the password is written into the RFID The card is distributed to legitima...
