It will be readily understood that the lines between the modules or components shown in fig. 1 may represent communication connections between the various parts of the various systems or data transmission, upload or request relationships between each other or one-way.
According to some preferred embodiments of the present invention, the radio frequency access control system is configured to distinguish whether the book is demagnetized according to values of an AFI security bit and an EAS security bit of a radio frequency tag of the book.
Further preferably, the radio frequency tag is a high frequency tag or an ultra high frequency tag, and the mobile terminal has an NFC module or a code scanning module. The code scanning module can be a code scanning module such as a WeChat code scanning module, a Paibao code scanning module, or a module capable of reading other two-dimensional codes or other types of bar codes.
Further preferably, the library self-service book borrowing system comprises a plurality of library sub-areas belonging to the same large circulation area, and each library sub-area is respectively configured to have a value of a universal demagnetization bit so as to be used as a demagnetized mark and also has a value of a theft-proof bit.
As for the value of the security bit of the radio frequency tag of the book and the demagnetization configuration, for example, a specific configuration as described below may be adopted, wherein the radio frequency access control system may also be referred to as an online RFID access control system in the following description.
For example, the online RFID access control system distinguishes whether the book is demagnetized according to the AFI and EAS safety bit values of the book RFID high-frequency tag, if the book is not demagnetized, the online RFID access control system sends a book lending state query request to the middleware system, and controls whether the alarm module alarms or not according to the request result.
Optionally, the online RFID access control system includes an anti-theft method compatible with mass circulation, in order to be compatible with mass circulation policies, the mobile phone book borrowing system uses a different anti-theft place value from that of other libraries, and even if the library is not borrowed, the other libraries taken to the mass circulation area do not give an alarm, so as to prevent the problem of false alarm of the library caused by the books borrowed by code scanning of the mobile phone.
And the online RFID access control system detects that the value of the RFID chip theft-proof position accords with the value set by the current library and considers the books which are not borrowed and the value of the current library theft-proof position is not matched, and all the books are considered as the borrowed books.
Optionally, the online RFID access control system may include an online RFID high-frequency access control system and an online RFID ultrahigh-frequency access control system.
In some optional embodiments of the present invention, the anti-theft bits used by the online RFID high-frequency access control system are an AFI bit and an EAS bit of an RFID high-frequency tag, and in order to ensure compatibility of mobile phone code scanning and book borrowing for large circulation of a book area, values of anti-theft bits in each general hall and each branch hall in the large circulation area are different. For example, the AFI maximum value is 0XFF (hexadecimal), the EAS value is 0/1, the maximum identifiable state bits are arranged by combining the AFI and EAS values, the value of one reserved state bit is the value of a general demagnetizing bit (no alarm identifier/demagnetized identifier) which is widely circulated in an area, and the maximum identifiable state bits are 509 museum alarm values; according to some manufacturer chips may not have/not enable the EAS bit feature, a minimum of 255 status bits can be identified, one bit is reserved as a general demagnetization bit, and a minimum of 254 branch room alarm bits can be identified.
For example, in some application examples of the system according to the above embodiment of the present invention, the high frequency tag anti-theft general degaussing identifier of a certain city region library is AF 0XC2 (hexadecimal), EAS is 0, the value of a certain library anti-theft bit is 0X07 (hexadecimal), AF before book lending is 0X07 (hexadecimal), EAS is 0, and after being borrowed by a fixed self-service terminal, AF is 0XC2 (hexadecimal), EAS is 0.
For another example, the general degaussing flag for high-frequency tag theft prevention in a library in a certain city is AF 0X0A (hexadecimal), EAS is in a non-enabled state, the value of the theft prevention bit in a library is 0X07 (hexadecimal), AF before book lending is AF 0X07 (hexadecimal), EAS is in a non-enabled state, and after borrowing by a fixed self-service terminal device, AF is 0X0A (hexadecimal), EAS is in a non-enabled state.
The anti-theft position used by the online RFID ultrahigh frequency access control system is a value in an EPC of an RFID ultrahigh frequency tag, and in order to ensure the compatibility of mobile phone code scanning and book borrowing to the large circulation of a book area, the anti-theft positions of each general center and each branch center in the large circulation area have different values; the length of EPC content is generally more than or equal to 8 bytes, one or a plurality of bytes can be selected to store the value of the anti-theft bit according to the actual situation of each region, and the value of a status bit is generally reserved as the value of a general demagnetizing bit (non-alarm mark/demagnetized mark) which is widely circulated in the region.
According to some preferred embodiments of the present invention, the library database is further configured to record hardware number information of a radio frequency tag of the book, and the radio frequency access control system is further configured to request the library database to verify the lending status of the book by querying the hardware number information of the book based on the read radio frequency tag.
According to some preferred embodiments of the present invention, a heartbeat package mechanism is configured between the library database and the radio frequency access control system and/or between the middleware system and the radio frequency access control system to ensure a long connection relationship between the library database and the radio frequency access control system, and the heartbeat package mechanism is configured to switch the radio frequency access control system to an offline operating mode if the radio frequency access control system does not receive a heartbeat package sent by the library database or the middleware system for more than a preset time. Based on this configuration, the rf access control system automatically switches to the offline mode after several attempts within a certain time (such as 2 seconds, 5 seconds, etc.) without connecting to, for example, a middleware system server.
On this basis, it is further preferred that, in the offline operating mode, the radio frequency access control system is configured to determine whether to alarm based on whether the book is demagnetized.
Alternatively, in accordance with still other alternative preferred embodiments, in the offline operating mode, the radio frequency access control system is configured to store the detected radio frequency tags of the books that have not been demagnetized locally, and to resume the normal operating mode when the heartbeat packet is received again. And in the normal working mode, the radio frequency access control system is configured to firstly request the library database to verify the lending state of the corresponding book based on the locally stored radio frequency tag, and then determine whether to alarm or not according to the result returned by the library database.
According to the preferred mode, the system is compatible with the original off-line radio frequency access control equipment or system like other embodiments, meanwhile, a large amount of unnecessary alarm or misinformation caused by poor network conditions and other factors can be reduced, and the normal operation of the whole system can be recovered quickly after the network or communication condition is recovered.
According to some preferred embodiments of the present invention, the radio frequency access control system is communicatively connected to the library database via the middleware system.
According to some preferred embodiments of the present invention, the mobile terminal performing a book borrowing operation uploads information of the borrowed book to the middleware system based on the read barcode, and the middleware system is further configured to be able to request the library database to update its recorded lending state of the book according to the information of the borrowed book uploaded by the mobile terminal.
According to some preferred embodiments of the present invention, the library database includes a white list sub-module configured to update and record all books lent by communication with the mobile terminal, the middleware system, or the radio frequency access control system. The method is more suitable for small and medium libraries, and is helpful for optimizing resource allocation under the condition that the total book lending amount in normal operation is not too large.
According to some preferred embodiments of the present invention, the library database includes a plurality of library book sub-modules, each of the library book modules being configured to update and record all outstanding books in a corresponding library region according to the books stored in the library region. And the mobile terminal, the middleware system or the radio frequency access control system are configured to be able to verify whether a book currently passing through the radio frequency access control system belongs to an unrelent book by communicating with a corresponding library book sub-module and requesting it.
According to some application examples, in the above preferred embodiment, the library book submodule can adopt a mode of comparing in a library list, which means that a certain reading room of the library is hidden in a book shelf list, when a reader borrows out a certain book of the reading room, the system rejects the book from the reading room in the book shelf list, and when the online security access control system of the reading room compares the book, the book is found not to be in the library list, and is directly released. If other books in the reading room pass through the safety door, the alarm is not given. The principle followed by the list comparison mode is that each reading room only carries out safety theft prevention on the books on shelf in the reading room. Since the number of books hidden in the book shelf of the reading room is limited and can not be infinitely increased under the condition that the space of the reading room is not changed, the system performance can be ensured, and the scheme is suitable for large libraries and is beneficial to controlling peak resources required for realizing the functions.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
