Description
Technical field
The invention belongs to library management system technical field more particularly to a kind of book management systems based on campus network
And management method.
Background technique
Traditional libraries use " safe magnetic stripe bar code ", i.e., using safe magnetic stripe as the safety assurance of books, bar code
The way to manage of identity card as books is managed the books in library.In recent years, Radio Frequency Identification Technology work becomes
Most technology of Internet of things is applied in library management.As " library movable point inspection vehicle and its library search are made an inventory, whole frame side
Method " and " Intelligent bookshelf based on work technology " etc..Although in recent years, taking care of books as far as possible towards unmanned direction into
Row, but undeniably, being directly entered reading room to carry out artificial search by reader is still current main way.Some
Large-scale library can inquire books region and bookshelf information by the Library Inquiry System that library provides, still,
In concrete practice, bookshelf stands in great numbers, and wherein, Lian Fangxiang is difficult to find out people, and the very big time will be spent by finding books still
And energy.Therefore, if people and books can be positioned in real time in the specific location in library, and navigation is provided, figure will be greatlyd save
Book searches the time.
In summary, there are main problems for the prior art:
In the prior art, indoor position accuracy is low, cannot achieve books precise positioning.
It relies primarily on manually, the degree of automation is low.
It is poor to manage, and finds books needs and takes a significant amount of time.
Summary of the invention
The present invention against the above technical problems, provides a kind of book management system and management method based on campus network.
The invention is realized in this way a kind of taking care of books method based on campus network includes:
Step 1 reads the RFID chip needed to give back on books using the first RFID reader, obtains books corresponding information, benefit
With the thickness information of optoelectronic switch measurement books, the book information that will acquire and thickness information are stored in database；
Books are pushed to figure using promotion and dividing apparatus according to the books position of database transmission, thickness information by step 2
Book answers the storage device corresponding points of placement location, is pushed books in storage device from corresponding points using pushing equipment；
Step 3, according to the books thickness information that database transmits, the amount of capacity for storing control unit and storage device is done pair
Than issuing prompting if storage device is completely held, user being reminded to store the books in storage device to the bookshelf of reference numeral
On；
Step 4 needs book RFID chip with the reading of the second RFID reader, and acquisition books should put books location information and include
Books bookshelf number etc., and bookshelf corresponding with itself number compares, if comparison is consistent, books deposit information is sent to
In taking care of books module, while showing that books should put specific location includes the information such as which row；If books should store bookshelf volume
It is number not consistent with itself number, then issue promptings, prompting user's books placement position mistake simultaneously shows that books correctly put book
Books are placed at correct number bookshelf by frame number；
Step 5, call database in all information, to student's book borrowing and reading time, book borrowing and reading quantity, books give back the time,
Books position is managed；Simultaneously according to the first campus network signal receiver, the second campus network signal receiver, transmission books
Location information checks the accurate positioning of books, while being stored in each book of information inspection according to the books of the second RFID reader transmission
The catalogue and the existing catalogue for putting books that books should be stored on frame, are according to the actual situation adjusted books placement position；
It calls simultaneously and checks borrowing personnel, borrowing number and borrow the time for every book in database.
Further, step 5 books position be managed in localization method include:
It carries out off-line phase and on-line stage carries out simultaneously；
Off-line phase position fixing process are as follows: the campus network signal phase data for acquiring each predetermined position, by signal link
Analysis, carries out credible carrier wave screening first, then calibrates for error to carrier signal, and the phase property deposit after calibration is referred to
Line library；
On-line stage position fixing process are as follows: acquire the campus network signal phase data of position to be measured in real time, after carrying out data processing, obtain
To the signal characteristic of respective point；
After the completion of off-line phase positioning and on-line stage positioning, carried out using to the collected books of capture card position signal to be measured
Filtering, and spectrum analysis is carried out to books position signal to be measured and provides foundation and fingerprint base On-line matching for the differentiation of hard spot, it is defeated
Optimum out completes the positioning of positioning book.
Further, it is filtered using to the collected books of capture card position signal to be measured, and to books position to be measured
Signal carries out spectrum analysis and provides for the differentiation of hard spot according to fingerprint base On-line matching, specifically includes:
