As a kind of radio frequency technology, RFID can read and write data by using radio signals for identifying specific targets without the need of mechanical and optical contact, and has many advantages such as fast, safe, and reusable. By 2016, RFID technology has been used in China's libraries for a full decade. From the sporadic fire to the widespread use in the library industry today, it can be said that the application of RFID technology in libraries has promoted the library service model. The development and changes in many aspects, such as management platforms and service content， they have not only changed the traditional circulation methods, but also expanded the space and time of services. For librarians, the use of RFID technology not only reduces the difficulty of the work, but also improves the effectiveness of the service. The combination of library and RIFD technology has undoubtedly brought great convenience to readers and librarians. In the future, RFID technology will continue to play an important role in the development of smart libraries.
RFID book inventory intelligent robot design requirements and implementation conditions:
Design requirements: The scope of robot application should include both open frame and closed frame. The case of book inventory under open frame mode should be more complicated than that of closed frame. This paper discusses the automatic calculation of book inventory under the open frame mode. Design requirements include the following:
Self-test function of the robot. Before starting a series of work, you must complete the self-test of the equipment to ensure that the various components can operate normally, and whether the battery power supply can support the equipment to complete this order.
Get the actual situation topology of the current map bookshelf. The shelf information of the current bookshelf can be planned in the system, which can make the device have an objective judgment and analysis on the current shelf information before running.
The positioning of the robot and the path of the trajectory. Firstly, it is necessary to construct the map of the entire open environment effectively, and plan a reasonable travel route, and automatically return to the preset line when the device deviates from the position. If you encounter obstacles on the route you are on, you should wait a little and then make a new route plan based on the actual situation.
RFID technology is used to count the books in the shelf, and the robot arm moves in the front, back, left, and right directions of the three axes when the book is counted. The robot arm of the book should have a 3-axis movement function to ensure that there is no omission in the book inventory process. After the completion of the inventory task, a summary of the situation is formed. After the end of the inventory operation, a summary of the process of the inventory is required and presented to the librarian.
