Embodiment
As shown in Figure 1, the technical scheme that its technical matters that solves the utility model adopts is: device package such as keyboard, antennas in a container, master control borad is packaged in another container, is welded with functional modules such as keyboard control chip, card reading module, central processing element, storage chip on the master control borad.Keyboard is connected with the keyboard control chip of master control borad by connecting line, and antenna is connected with the Card Reader chip of master control borad by connecting line.Card reader is connected by twisted-pair feeder or winding displacement connecting line less than 10 meters with master control borad, realizes mutual communication;
The annexation of each module of the utility model:
Circuit diagram shown in Fig. 2,3, CPU (central processing unit) circuit 1 is used for being connected with keyboard control chip HD7279 8, Card Reader control module 9 with socket 6, charactron demonstration 7, the demonstration of card reader line respectively with on data-carrier store 2, external unit control circuit 3, communicating circuit 4, clock circuit 5, the primary controller, forms the primary controller circuit board jointly.
Circuit diagram as shown in Figure 4 is used on the card reader being connected with keyboard 12, buzzer circuit 13, pick-proof switch 14, card reading antennas 15, pilot lamp and KBD-LIGHT 16 respectively with the socket 11 of primary controller line, forms the card reader circuit plate jointly.
Be used on the primary controller of primary controller circuit board top with the socket 6 of card reader line by less than being used for being connected on the card reader on 10 meters connecting line and the card reader circuit plate with the socket 11 of primary controller line.
The utility model principle of work:
The personnel that hold are placed on non-contact card in the Card Reader zone of card reader, the antenna 15 of card reader can send wireless signal and activate smart card, smart card is activated the back information of self is fed back to antenna by wireless transmission, the antenna that has received card image is sent to the card reading module 9 of controller through connecting line, by after the card reading module decoding data being issued CPU (central processing unit) 1, the time that provides in conjunction with clock circuit 5 by CPU and the parameter of data-carrier store 2 stored, whether decision opens the door through safety verification; If CPU judges that the holder can enter, will control external unit control circuit 3, make electric lock open, thereby the personnel's of realization is current; If CPU judges that the holder cannot enter, will can not control door-lock opening.The result of CPU drives charactron 7 by chip HD72798 and shows.
Personnel can be provided with the partial parameters of system by keyboard 12, also can input password by keyboard, can also be by using this keyboard realization other extended operation to primary controller; The card reader the inside can also extended device, pick-proof switch 14, pilot lamp 16, loudspeaker or hummer 13 in addition.
Other device except that master control borad can be expanded in controller the inside, and its communication interface 4 is based on RS485, RS232, yet can also expand to CAN bus, TCP/IP, GPRS, CDMA to communication interface, and realization and computing machine or other control box are networked.
