Description
Technical Field
The utility model relates to an entrance guard's circuit, concretely relates to identity card information through bluetooth or TTL communication reads and punches card identity authentication's entrance guard's owner accuse circuit.
Background
At present, a traditional access control machine relies on a property side to issue cards to complete the management of resident personnel, for example, an access control machine manufacturer makes a mother card for the property personnel, after the property personnel register information for a resident, the mother card is used to start a card adding program of the access control machine, then a white card is swiped, a physical number of the white card is registered to the access control machine, and then the resident can use a newly registered door to swipe the card to open a door.
Along with the rise of wisdom community, the district that adopts thing pipe platform can use the card reader to read at the computer end through the property personnel and type into entrance guard's card physical number to the platform, is sent the entrance guard machine to the card number of newly increasing by the platform again, and later the resident family can use the door card of newly handling to realize opening the door.
In summary, at present, card swiping authentication has two modes of local storage of the access control machine and platform side authentication, one mode is that an access control card number is stored in the access control machine and is locally compared during card swiping, the other mode is that the access control card number is stored in a platform, the access control machine reads the card number and then compares the card number with the platform, and no matter which mode is used, the door is opened as long as the comparison is passed, otherwise, the access control prompts 'illegal card'.
The card issuing efficiency of the mother card mode is low, property personnel need to punch cards in each access control machine required by residents in a community to increase sub cards, and the residents generally need to wait for 1-2 days to complete the card issuing.
The property can not ensure the security of registering the door card, the property of the residential quarter usually only makes the card selling according to the requirements of the owner and does not ask the owner to transact the card, even if the renters can transact the card at will only by providing the number of the door.
The property of some management card-issuing of use platform supports identity card correspondence, but the cost of identity card reader is expensive, is unfavorable for the property popularization on a large scale.
No matter the card number of the resident exists on a platform or the entrance guard machine, when the entrance guard machine has a non-power failure, the user can not normally swipe the card to open the door. For example, when the door lock is not powered off when the door lock is in a blank screen state, a standby state, no response state and the like, the door lock cannot be driven to unlock by the door lock, and a resident can only wait for the indoor machinery outside the door.
