Abstract
The utility model relates to a dual-safety access control device. The dual-safety access control device comprises a major door and a minor door, wherein the major door comprises a major door shell body, a read-write module, an alarm module, a first antenna and a second antenna; and the minor door comprises a minor door shell body. The dual-safety access control device is characterized in that: the major door shell body is provided with a magnetic strip receiving antenna; the first antenna, the second antenna and the read-write module are arranged beside the magnetic strip receiving antenna; the first antenna and the second antenna are distributed up and down in a separate manner, corresponding to a zone at the middle part of the major door shell body; and a magnetic strip transmitting antenna which is corresponding to the magnetic strip receiving antenna is arranged in a cavity of the minor door shell body. By integrating the anti-theft function of a magnetic strip and an electronic label, the dual-safety access control device lowers mutual interference between magnetic strip access control and RFID access control to the degree of mutual noninterference. Therefore, the dual-safety access control device can carry out anti-theft detection on a book with the magnetic strip and/or the electronic label. Meanwhile, the opening and closing of an RFID antenna are controlled by a human inductor, which can eliminate harm to human bodies due to long-time radiation of the RFID antenna. Moreover, by adopting the modular design, the dual-safety access control device is more convenient for maintenance.
Description
Technical field
The utility model relates to a kind of safety-door device, refers to that specifically a kind of being applied to is used for detecting the safety-door device whether books are normally borrowed in the places such as library.
Background technology
Prevent that at present the stolen safety door of books from mainly containing two kinds: a kind of safety-door device that is based on magnetic stripe, magnetic stripe promptly is installed in books and reference materials, when books administrative staff is borrowed formality for the reader handles, magnetic stripe in these books is carried out demagnetization, and after this reader just can waltz through this safety-door device.Otherwise after the magnetic stripe anti-theft technique in the safety-door device detects the magnetic of magnetic stripe, can send corresponding alerting signal.
Another kind is based on the safety-door device of electronic tag (RFID) recognition technology, be the safety door of CN201017402Y " detecting the safety-door device of usefulness " so just having disclosed as Chinese patent Granted publication number, this safety door comprises the door shell body, be arranged in the installing plate of door shell intracoelomic cavity and be fixed on read write line, antenna and alarm module on the installing plate, wherein antenna has two, receive frequency range and departs from the installing plate that is fixed in the door shell body central region between 902MHz～928MHz mutually stragglyly.During use, control computer links to each other with read write line by network interface, to the read write line transmitting control commands.When having this safety door of books process of electronic tag, the radio frequency signal that antenna in the safety door sends can activate the electronic tag in the books, make electronic tag work, and its information sent to antenna, antenna is sent to read write line by the radio-frequency cable line again with the electronic labeling information that receives, read write line sends electronic labeling information to control computer by decoding, and control computer is compared to the data in electronic labeling information and the database.Do not borrow formality if the books of electronic tag correspondence are handled, then can start alarm module and carry out sound and light alarm.Borrow formality if the books of electronic tag correspondence have been handled, then the reader can successfully pass through this safety-door device.
Obviously, adopt above-mentioned two systems respectively after, can play antitheft effect to a certain extent.But, can produce wrong report because magnetic stripe demagnetization sometimes is insufficient for the former; And also can't writing information in the magnetic stripe, so that make troubles to management work; Moreover when running into many books and pass through safety door together, this magnetic stripe safety-door device can't be judged which books is not handled and borrow formality.And the latter, though can accurately judge and do not handle the books of borrowing formality, verification and measurement ratio is little, also can't carry out relevant detection for the books that only have magnetic stripe simultaneously.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, can carry out burglar detection to the books that magnetic stripe and/or electronic tag have been installed simultaneously and provide a kind of, and have the verification and measurement ratio height, can accurately judge the dual safe entrance guard device of every books of not handling to borrow formality again.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this dual safe entrance guard device comprises the main door put relatively and from door, wherein main door includes main door shell body again, be arranged in main door shell intracoelomic cavity electronic label read-write module, alarm module and first, second antenna, and describedly include from the door shell body from Men Ze, it is characterized in that: in the described main door shell body magnetic stripe receiving antenna is installed also, above-mentioned first, second antenna and module for reading and writing are positioned at one side of this magnetic stripe receiving antenna, and first antenna and second antenna be spaced apart and corresponding to the central region of main door shell body up and down, describedly then is equipped with and the corresponding magnetic stripe emitting antenna of above-mentioned magnetic stripe receiving antenna in the cavity of door shell body.
For eliminate RFID length of antenna's time radiation may to human body bring harm, on described main door shell body, the human inductor that is used for opening and closing described first antenna, second antenna can also be installed, this human inductor can adopt infrared ray or other induction technologies, when when certain limit is sensed human body, it can send signal and give module for reading and writing or software, is used for opening first, second antenna; In the time of setting, it is close that this human inductor is not sensed human body, then can directly send the control signal of closing first, second antenna work again, makes first, second antenna reduce radiated time when realizing operate as normal.
For fear of the phase mutual interference of two kinds of checkout equipments, described magnetic stripe receiving antenna respectively and the distance between described first antenna, second antenna and the module for reading and writing be not less than 50mm.
Consider that the person of checking out is current swimmingly, can also comprise a secondary door, this pair door be placed in above-mentioned from door one side and make described from door between secondary door and main door, this pair door also has secondary door shell body, and also described magnetic stripe receiving antenna and first, second antenna of column distribution also are installed in this pair door shell body.At this moment, on this pair door, human inductor can be installed equally, be used for opening and closing first antenna and second antenna in the described secondary door, to reduce the radiation of antenna.
In above-mentioned each scheme, described main door, on door and secondary door, all the acoustic-optic alarm that links to each other with alarm module can be installed.
Compared with prior art, because the utility model integrates magnetic stripe and electronic tag is antitheft, and by magnetic stripe receiving antenna and RFID gate inhibition's antenna, the reasonable Arrangement between the module for reading and writing, and the magnetic stripe emitting antenna is installed in the mode in the door, make magnetic stripe gate inhibition and RFID gate inhibition mutually mutual interference drop to the degree that is independent of each other, thereby the utility model is to having magnetic stripe and/or electronics target books can carry out burglar detection; Simultaneously by the open and close of human inductor control RFID antenna, can eliminate the harm that RFID length of antenna's time radiation may cause human body; Secondly, adopt modular design, safeguard more convenient.
