Access control system based on active RFID technology and face recognition technology

Technical field

The utility model relates to gate inhibition's technical field, is specifically related to the access control system based on active RFID technology and face recognition technology.

Background technology

RFID(Radio Frequency Identification, radio-frequency (RF) identification) technology, claim again electronic tag, radio frequency identification, it is a kind of communication technology, can identify specific objective and read and write related data by radio signals, and need not to set up machinery between recognition system and the specific objective or optics contacts.Rfid interrogator also divides portable with fixed, and the RFID technology is used very extensively at present, and for example: the library, gate control system, food security are traced to the source etc.

The RFID electronic tag is divided into two kinds of passive label and active tag.Active tag self is with powered battery, and read/write distance is far away, is also referred to as active label.Passive label is by the required energy of acquisition work in the magnetic field of reader generation, and reading/writing distance is then nearer, is also referred to as passive label.

Chinese patent literature CN202183131U has proposed a kind of REID and has used gate control system, this gate control system is by card sender, access controller, reader, electric lock, computer and communication accessory form, the computer expert crosses communication accessory and connects respectively card sender, access controller, reader, the access controller electric lock, disclose in this patent documentation and a kind of the RFID technology has been applied to mode in the entrance guard management, single (two) are installed to reader on the doorway of appointment, provide corresponding RFID access card to corresponding personnel in advance by the hair fastener center, realize difference discrepancy personnel are managed.Lose, falsely use and event and the behavior such as forgery but this RFID access card exists, can be at an easy rate in violation of rules and regulations or go beyond one's commission and cross gate control system, have potential safety hazard.

In order to solve the problems of the technologies described above, Chinese patent literature CN102354409A discloses a kind of access control system based on recognition of face, this system comprises the man face image acquiring module, microprocessor module, communication module, the Background control computing machine, access controller, the man face image acquiring module transfers to microprocessor module with the facial image that collects, facial image after will processing by communication module after treatment transfers to the Background control computing machine, the Background control computing machine is compared facial image in this facial image and the system database, if the facial image that collects is present in the said system database, then sends one and control signal to access control system and go to carry out the action of opening the door.Disclosed technical scheme in this patent documentation, although can solve the problem of the potential safety hazard that exists in the RFID gate control system, but, everyone facial image in the system database only has several, and the user when the man face image acquiring module is advanced pedestrian's face image acquiring owing to reasons such as environment, light or standing places, the facial image that collects and the facial image in the system database differ greatly, wrong report appears easily, discrimination is low, cause user's needs repeatedly before the man face image acquiring module, to gather facial image, lose time.

The utility model content

For this reason, to be solved in the utility model is that gate control system of the prior art can't solve simultaneously and has potential safety hazard and the low technical matters of discrimination, thereby proposes a kind of access control system based on active RFID technology and face recognition technology.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of access control system based on active RFID technology and face recognition technology comprises active RFID device, face identification device and central controller;

Described face identification device comprises that facial image obtains equipment, is used for obtaining facial image and sending the facial image that obtains to described central controller;

Described active RFID device comprises the active RFID card reader that is arranged on gate inhibition's end and the active RFID device that is arranged on user's terminal, described active RFID card reader is used for reading canned data in the described active RFID device, and sends described information to described central controller;
