Description

Technical Field

[0001] The present invention belongs to the technical field of sports equipment, and in particular, relates to a self-service basketball taking and returning accounting device. Background Art

[0002] In modern sports facilities and public sports venues, the borrowing, returning and storage of basketballs often face many challenges. Traditional basketball management methods rely on manual borrowing and returning, which is not only time-consuming and inefficient, but also easily leads to the loss or damage of basketballs. In addition, due to the large size of basketballs, traditional storage methods often take up a lot of space, which is not conducive to the effective use of space. In addition, the location monitoring and usage time management of basketballs during use are also a major problem, which is crucial for maintaining public order and the effective management of sports equipment.

[0003] With the advancement of science and technology, the application of automation and intelligent technology is becoming more and more extensive, which provides new possibilities for solving the above problems. For example, the application of near-field communication (NFC) technology can realize the rapid identification and data tracking of basketballs, while the automated compression and inflation mechanism can effectively solve the problem of large basketball storage space. In addition, the application of remote monitoring technology can easily monitor the use location of basketballs to ensure that basketballs are not taken out of the designated area. Therefore, the development of an integrated self-service retrieval and accounting device, which aims to improve the management efficiency of basketballs, optimize the use of storage space, and realize real-time monitoring and management of basketballs, has important practical significance for modern sports venues.

[0004] According to the relevant documents that have been made public, the technical solution with publication number CN113713357B proposes a sports equipment placement rack, which arranges recessed bases of various specifications on the rack so that different sports equipment can be placed firmly on the rack; the technical solution with publication number KR1020090061200A proposes a movable basketball stand, which can transport a large number of basketballs at one time through multiple internal supporting supports and a large-capacity storage bin; the technical solution with publication number US06575853B1 proposes a portable beach basketball system, which is equipped with multiple components and anchoring devices that can be fixed and moved on the sand, so as to realize rapid basketball activities on the beach.

[0005] The above technical solutions all propose technical solutions for ball management or transportation, but there is currently a lack of technical solutions for implementing unmanned self-service basketball retrieval devices in public venues. The implementation of relevant technologies can help improve management efficiency and user experience in schools, basketball business venues, etc.

[0006] The foregoing discussion of the background art is intended only to facilitate an understanding of the present invention. This discussion does not acknowledge or admit that any of the material referred to is part of the common general knowledge. Summary of the invention
