Description

TECHNICAL FIELD

[0001] The utility model relates to intelligent storage technical field, concretely relates to a kind of superhigh frequency RFID intelligent storage cabinet. BACKGROUND

[0002] The storage cabinet is a kind of equipment for storing articles. The traditional storage cabinet has relatively simple performance and single application scenario. In recent years, with the continuous popularization and application of superhigh frequency RFID technology, the superhigh frequency RFID technology is combined with the storage cabinet, and the intelligent storage cabinet emerges as the times require. The intelligent storage cabinet is internally provided with an antenna board based on RFID and a control device. The inventory of articles in the storage cabinet can be automatically sensed based on the superhigh frequency RFID technology, and automatic recording of article taking is realized. Meanwhile, the system can develop certain permission function for different operators. The corresponding articles can be developed according to the registration of different personnel, and corresponding use records are generated. The intelligent storage cabinet can be used as a daily intelligent tool cabinet and an intelligent file cabinet, and can also be applied to an article management system such as a medical reagent cabinet.

[0003] However, the superhigh frequency RFID cabinet on the market is plagued by shielding problems and signal overflow problems for manufacturers and users.

[0004] Since the superhigh frequency RFID intelligent storage cabinet requires good shielding performance, the cabinet door and the cabinet body need to be closely attached. Most of the intelligent storage cabinets on the market use shielding strips for sealing to reduce the gap between the cabinet door and the cabinet body and avoid RFID signal overflow as much as possible. However, such shielding strips also cause many problems.

[0005] Since the shielding strip is a soft conductive material, the cabinet door and the cabinet body need to be pressed tightly to achieve the shielding effect. However, the intelligent storage cabinet needs to be closed very hard to press the shielding strip, which affects the user experience. Due to the characteristics of the shielding strip, long-term pressing will cause the resilience of the shielding strip to weaken, resulting in poorer shielding effect and more serious RFID signal leakage problem. Due to the unsatisfactory shielding effect, most manufacturers will choose to reduce the reading power of RFID to balance the stability problem caused by signal leakage, at the expense of the speed and accuracy of RFID reading.
