A robot-based book staggered sorting system and method

technical field

The invention belongs to the technical field of library management, and in particular relates to a robot-based book staggered arrangement system and method.

Background technique

As a technology-sensitive service organization, the library is quick to perceive and apply new technologies. The intelligent development goal of self-service and artificial intelligence as the editor will lead the future development of the library. However, no matter how intelligent and intelligent, paper books will not disappear. Libraries should provide users with an environment that facilitates information discovery, utilization, creation and management through modern information technology, and should also pay attention to providing greater convenience for managers.

Although a large number of library management systems have emerged in an endless stream in recent years, they generally do not pay attention to the error checking and protection of books themselves, and most of them have low technological content, which has resulted in a waste of books and technological resources. In addition, there is no well-established high-tech book fault-finding auxiliary system, which leads to the phenomenon that the data on the client side is often not equal to the location of the actual book in the library.

The above situations all show that the technology of library management system in my country is still in the trial stage at this stage, and there are still large technical gaps, especially in the error checking of the placement of books. Therefore, due to the above reasons, at this stage, my country There is an urgent need for relevant library book management assistants to alleviate the contradiction between the increasing number of library books and the increasing difficulty of book management.

With the improvement of informatization and network construction, more and more libraries are adopting RFID book management system and implementing RFID management system, which mainly realizes the following functions: automatic book borrowing and returning, access control system, automatic positioning of books, automatic inventory of books , book statistics, etc., so theoretically speaking, the use of RFID technology can easily find the books on the bookshelf, and the staff can easily count the books, which greatly saves manpower and material resources. But in fact, during the research, we found that due to the frequent flow of books, the failure of books to be put on the shelves in time, and the books being brought into other reading rooms due to open reading, etc., books were placed in disorder and difficult to organize. Both library staff and readers have been a nuisance, and the location of books displayed on mobile devices is often inconsistent with the actual location of the books.

In order to solve the above-mentioned deficiencies of the prior art problems, the present invention therefore provides a robot-based book staggering system and method, which utilizes the integration of the Internet of Things technology and traditional libraries, and uses the combination of UHFRFID technology and image capturing technology. It also has a modular design, which can facilitate customer management systems and improve library management by using big data analysis. It can also significantly reduce library maintenance and upgrade costs, filling the current lack of maintenance in library RFID management systems. Blank, it achieves the effect that 1 machine can be equivalent to the workload of 5 staff members, which has high practical significance; it uses Alibaba Cloud MySQL server to realize the combination of UHF RFID and image capture technology, so that the library can achieve The purpose of quickly searching and arranging wrong books is to improve the management level, so that readers can find the target books at any time, which greatly improves the effect of readers' satisfaction.
