Access control device

Abstract

An access control device includes a main system and an active proximity card, and the main system has settings of a first received signal intensity and a proximity card transmitter signal intensity, and the active proximity card has the setting of the proximity card transmitter signal intensity. If the setting of the proximity card transmitter signal intensity of the active proximity card is unequal to the setting of the proximity card transmitter signal intensity of the main system, then the setting of the proximity card transmitter signal intensity of the active proximity card will be changed to a setting equal to the setting of the proximity card transmitter signal intensity of the main system to facilitate users' access and save the power consumption of the active proximity card.

Description

technical field [0001] The invention relates to an access control device, especially an access control device which uses an active induction card to control the opening or closing of the access control. Background technique [0002] Access control devices use identity verification devices to control or record the entry and exit of people in specific areas. They are widely used in residences, office buildings, parking lots, hotel rooms, and dormitories. Traditional access control devices use hosts to connect to gates or iron rolling doors, etc. , when the user wants to enter and exit, it is to press the remote control to control the host to open or close the door, but this method requires the user to press the remote control, which is quite inconvenient. Therefore, some related companies have developed an active proximity card , this kind of active proximity card is equipped with a battery inside, and the power provided by the battery inside the active proximity card transmit...

[0002] Access control devices use identity verification devices to control or record the entry and exit of people in specific areas. They are widely used in residences, office buildings, parking lots, hotel rooms, and dormitories. Traditional access control devices use hosts to connect to gates or iron rolling doors, etc. , when the user wants to enter and exit, it is to press the remote control to control the host to open or close the door, but this method requires the user to press the remote control, which is quite inconvenient. Therefore, some related companies have developed an active proximity card , this kind of active proximity card is equipped with a battery inside, and the power provided by the battery inside the active proximity card transmits the control signal of the proximity card to the host for execution. Therefore, when the user approaches the host, the host will automatically execute the control signal , quite convenient, but because the stronger the signal transmission strength of the proximity card, the faster the power consumption, so if you want to extend the power of the proximity card, you must lower the strength of the proximity card’s sending signal to an appropriate range, but generally In other words, there may be hundreds or even thousands of proximity cards corresponding to a host, and it is very troublesome to adjust the strength of the proximity cards one by one.
