Library RFID sorting robot

Last year, Bao'an Library applied logistics sorting technology to book sorting, and 32 RFID sorting robots shuttled up and down the workbench in a busy and orderly manner. It is understood that the daily return volume of Bao'an Library reaches more than 10,000 books during the peak period, and it takes 2 days to complete the sorting and put them back on the shelves. After using the RFID sorting robot, 2,000 books can be sorted per hour, which greatly saves book sorting. time.

"Xiaozhi" and "Ruoyu" are more than 10 times more efficient than artificial

The intelligent sorting and returning system is divided into a sorting area and a box changing area. The sorting is divided into upper and lower floors. There are 28 sorting robots named "Xiaozhi" on the upper floor, and 4 handling robots named "Ruoyu" on the lower floor. Currently, there are 2 indoor self-service book returns, 2 outdoor self-service book returns, and 1 librarian book return.

After the reader returns the book by himself, the sorting table will read the RFID electronic tag on the book to identify the book information. The background management system is responsible for controlling and scheduling all robots, which can receive books according to system instructions, and arrange the optimal path for each robot to deliver books according to algorithm optimization. During the sorting process, "Xiaozhi" can also "perfectly" realize automatic avoidance, obstacle avoidance, autonomous charging, etc., without manual intervention at all, and can go to the designated slot to put it on its own.

At present, there are 30 sorting slots, which are allocated according to book categories and collection locations. The 4 self-service book return slots are operating at full capacity, and can sort 2,000 books per hour. All returned books are processed centrally on the sorting system. The heavy preliminary sorting work is efficiently and quickly completed by robots, and the efficiency is more than 10 times that of traditional manual sorting.

In the past, nearly 10,000 books needed to be returned, sorted, and put on shelves every day, which took a lot of energy and time. During the peak period of library traffic, some book boxes will be filled within half an hour to an hour, and need to be moved back and forth frequently. There are many kinds of books that have been moved back. The administrator needs to classify these books according to the books outside the library, the books of the branch library, and the books of the main library, and classify the books of the main library according to each functional area, and finally arrange them according to the call number. After all the sorting work is done, the divided books will be transported to different bookshelves.

Compared with manual sorting, the intelligent sorting and returning system not only saves time and effort, but also helps the staff reduce the links of collecting books everywhere and manual sorting in large quantities. It also has the advantages of small sorting errors, system reliability and strong scalability. . The sorting robot adopts static unloading. As long as the information in the drawing and written order is correct, the sorting error rate is theoretically zero; the system is composed of many sorting robots that operate independently, and the failure of a single robot does not affect the operation of the entire system.

The RFID sorting robot perfectly combines RFID technology with robots, which not only realizes the automatic identification of books, but also replaces manpower with machines in the sorting process, greatly improving the efficiency of book sorting. These application explorations are multi-faceted, or they are introduced into the link of operation and management to create new scenarios, or to further innovate in the way of data usage, and to integrate RFID technology with other technologies to achieve 1 plus 1 greater than 2 Effect. From an objective point of view, even the optimization of existing solutions is a manifestation of the spirit of innovation.
