In order to address the above problem the way that some design has used active electronic label and passive electronic label to unite two into one.The subject matter of the scheme that this unites two into one is that passive electronic label and active electronic label are systems independently, even swipe the card successfully, also can't confirm active part whether operate as normal, perhaps power shortage.The more important thing is that this kind method need add a cover passive system and connect database on active electronic label, hardware is changed bigger, and the input on hardware and software is bigger than normal, causes cost higher.
Summary of the invention
The present invention exists uniqueness and the imperfect problem of real-time in use for the way that solves prior art and use active electronic label and passive electronic label to unite two into one solves active electronic label, it is bigger to exist hardware to change, the cost technical problems of high provides a kind of active electronic label, brushing card device and gate control system.
For solving the problems of the technologies described above, the technical solution used in the present invention is a kind of active electronic label of design, comprise a single-chip microcomputer, described single-chip microcomputer has an interrupt pin, and described active electronic label comprises that also one is connected on the interrupt pin of described single-chip microcomputer and triggers the swipe the card Magnetic Sensor of frame of single chip microcomputers transmit under the action of a magnetic field.
Described Magnetic Sensor is tongue tube or Hall element.
The present invention also provides a kind of brushing card device, comprises the district that swipes the card, and the described district that swipes the card is provided with magnet.
The present invention also provides a kind of gate control system, comprise active electronic label and brushing card device, described active electronic label comprises a single-chip microcomputer, described brushing card device comprises the district that swipes the card, described single-chip microcomputer has an interrupt pin, described active electronic label comprises that also one is connected on the interrupt pin of described single-chip microcomputer and triggers the swipe the card Magnetic Sensor of frame of single chip microcomputers transmit under the action of a magnetic field, and the described district that swipes the card is provided with magnet.
Described Magnetic Sensor is tongue tube or Hall element.
Described gate control system comprises that also one receives the Card Reader substation of the described frame of swiping the card.
The present invention is by connecting a Magnetic Sensor on the interruption pin of the single-chip microcomputer that has active electronic label now, when active electronic label of the present invention is placed on swiping the card during the district of brushing card device that magnet is installed, Magnetic Sensor will trigger an interruption, and the prompting single-chip microcomputer enters duty at once and launches the hardwood frame of swiping the card to the Card Reader substation.The Card Reader substation receives the information of the frame of swiping the card, just know concrete which open to be stuck in and swipe the card, and can not misread other card.Simultaneously, because swipe the card frame and the action of swiping the card be simultaneously, do not need to wait for that electronic tag regularly launches, so improved the real-time of swiping the card yet.Thereby the present invention has solved active electronic label and has had uniqueness and the imperfect problem of real-time in use by the setting of simple Magnetic Sensor, and the hardware change is little, and cost is low.
Description of drawings
The present invention is described in detail below in conjunction with embodiment and accompanying drawing, wherein:
Fig. 1 is the schematic diagram of active electronic label of the present invention;
Fig. 2 is the schematic diagram of gate control system of the present invention.
Embodiment
See also Fig. 1.Active electronic label of the present invention comprises a single-chip microcomputer and a Magnetic Sensor, and wherein, single-chip microcomputer has an interrupt pin, and Magnetic Sensor is connected on the interrupt pin of described single-chip microcomputer, is mainly used under the action of a magnetic field to trigger the single chip microcomputers transmit frame of swiping the card.The other end of Magnetic Sensor is ground connection or connect power supply as the case may be.Magnetic Sensor can be tongue tube or Hall element.Owing to use the tongue tube can not power consumption, therefore, Magnetic Sensor preferably uses tongue tube.
See also Fig. 2.Brushing card device is used for corresponding with active electronic label, and brushing card device comprises a district that swipes the card that is used to swipe the card, and the district that swipes the card is provided with magnet.Magnet is mainly used in and produces magnetic field so that active electromagnetic tag is placed on the Qu Shangshi that swipes the card, and Magnetic Sensor is worked under the action of a magnetic field, inspires the single chip microcomputers transmit frame of swiping the card.
Gate control system comprises active electronic label, brushing card device, Card Reader substation and background system, wherein:
Active electronic label comprises a single-chip microcomputer and a Magnetic Sensor, and wherein, single-chip microcomputer has an interrupt pin, and Magnetic Sensor is connected on the interrupt pin of described single-chip microcomputer, is mainly used under the action of a magnetic field to trigger the single chip microcomputers transmit frame of swiping the card.Magnetic Sensor can be tongue tube or Hall element.Owing to use the tongue tube can not power consumption, therefore, Magnetic Sensor preferably uses tongue tube.
