The independent gate inhibition controller comprises a CPU carrying out data processing, a data memory connected with the CPU, a drive circuit connected with the CPU and a relay of a peripheral device, a communication interface circuit connected with the CPU, an MFCM200 kernel module connected with the CPU and an aerial connected with the MFCM200 kernel module. The independent gate inhibition controller can realize a non-contact reading intelligent card and carry out recognition processing to a plurality of intelligence cards simultaneously The independent gate inhibition controller is simple in operation and high in confidentiality.
Description
Affiliated technical field
The utility model relates to a kind of access controller.
Background technology
The structured flowchart of existing smart card door access machine as shown in Figure 1.Usually adopt contact intelligent card to come transmission information,, read the information in the card then, utilize the information in the central processor unit CPU transaction card, thereby realize that the gate inhibition is the function of access door control by contact intelligent card is inserted deck as information carrier.This smart card door access machine comprises: the deck that is used to insert smart card; Be connected with deck, the smart card that inserts in the deck is carried out the central processing unit that data write is handled; The communication interface that is connected with outside line by communication media; Be connected, be used to drive the drive circuit that relay is opened door with central processing unit and relay; And be connected, be used for memory which stores the data with central processing unit.In having the smart card door access machine of this structure, because smart card is discerned and smart card need be inserted in the deck of door access machine, it is slower to exist service speed, the long-term use damaged card and deck easily, thereby reduce the shortcoming in application life, and can not discern processing to a plurality of smart cards simultaneously.
Summary of the invention
For addressing the above problem, the utility model provides a kind of independent access controller, and this independent access controller can be realized smart card need not being inserted in the deck of door access machine can the identification intelligent card, and can also discern processing to a plurality of smart cards simultaneously.
The utility model is achieved through the following technical solutions, a kind of independent access controller, comprise by the CPU of carrying out the data processing, the data storage that is connected with CPU, the drive circuit that is connected with the relay of CPU and ancillary equipment, the communication interface circuit that is connected with CPU, also comprise MFCM200 nucleus module that is connected with CPU and the antenna that is connected with the MFCM200 nucleus module.
Described CPU adopts single-chip microcomputer to form.
Because adopt above-mentioned structure, independent access controller of the present utility model can be realized the contactless smart card that reads, and can discern processing to a plurality of smart cards simultaneously, and is easy and simple to handle, strong security.
Description of drawings
Fig. 1 is the block diagram of the structure of existing contact smart card door access machine;
Fig. 2 is the block diagram of the structure of independent access controller of the present utility model;
Fig. 3 is the circuit diagram of independent access controller of the present utility model.
The specific embodiment
The block diagram of the contact intelligent card door access machine of prior art as shown in Figure 1, the prior art of interlock circuit aspect belongs to known technology, is not described in detail here.Introduce present embodiment independence access controller below, shown in the block diagram of Fig. 2, a kind of independent access controller, comprise by the CPU of carrying out the data processing, the data storage that is connected with CPU, the drive circuit that is connected with the relay of CPU and ancillary equipment, the communication interface circuit that is connected with CPU, also comprise MFCM200 nucleus module that is connected with CPU and the antenna that is connected with the MFCM200 nucleus module.Described CPU adopts single-chip microcomputer to form.Described MFCM200 nucleus module adopts the MifareMFCM200 nucleus module of Philips company, and it combines REID and IC technology, passively in realizing blocking contacts with exempting from.It sends the information of one group of fixed frequency by sky alignment smart card, and receives the information of smart card emission, and this nucleus module can read while write the data on a plurality of smart cards.This nucleus module also is called the read-write radio-frequency maser.The described antenna that is connected with the MFCM200 nucleus module adopts built-in antenna.The communication interface circuit can adopt RS-485 communication interface circuit.The concrete circuit structure diagram of present embodiment is known technology as shown in Figure 3, introduces no longer in detail.
Simply introduce the method that this independent access controller and smart card, remote controller are used below,, here no longer the structure of smart card and remote controller is described in detail because the structure of smart card and remote controller belongs to prior art.Smart card employing capacity is the M1 card of the EEPROM of 8K, and every jig has unique sequence number, has strengthened security reliability like this.Certainly, also can adopt induction type ID card.This independent access controller also is equipped with corresponding IR remote controller, utilizes this IR remote controller to manage independent access controller, increases or delete the rights of using of a certain sheet smart card.During use, earlier this independent access controller is contained on the wall that leans on door, then smart card is placed in the induction zone of this independent access controller, be on the induction panel, independent access controller reads the information of every sheet smart card under the control of IR remote controller, and the authority of the every sheet smart card of corresponding setting, check is stored in information in the memory after correct then, and this independent access controller is joined card number can reach 2000, Card Reader apart from 5 centimetres in 15 centimetres.And by authorizing, a sheet smart card can use on a plurality of independent access controllers, can open a plurality of door locks, like this, can reduce the quantity of carrying smart card.When independent access controller enters duty, whether the continuous inspection of its central processor unit has smart card to enter induction zone, when personnel need enter, showing intelligence is stuck in unconnected gate and prohibits in the induction zone of antenna of controller, be on the induction panel, be confirmed to be effective card after the nucleus module empirical tests, read the information in the card, after the central processing unit calculation process with memory in data compare, judge whether that this subscriber card has the authority access door, if authority is arranged, give the drive circuit signal, drive relay door is opened; If lack of competence, goalkeeper can not open.This independent access controller can also be discerned processing to a plurality of smart cards simultaneously, and is easy and simple to handle, strong security.The above is a preferred implementation of the present utility model; should be understood that; do not break away from for the person of ordinary skill of the art under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
