Radio frequency identification device (RFID) intelligent cabinet

Abstract

The invention relates to a radio frequency identification device (RFID) intelligent cabinet which comprises a cabinet body and a control system, wherein a cabinet door is provided with a RFID access control system, and the RFID access control system is used for indentifying the identity information of a cabinet opening person and transmitting the identity information to a control system; and the cabinet body is internally provided with a RFID reader for reading a RFID electronic tag put on an article in the cabinet body, and the RFID reader is used for reading the information of the article and transmitting the information to control system. The cabinet door is arranged on the cabinet body by a door closer, and the door closer can automatically close the cabinet door even if a user forgets to close the cabinet door, so that the serious consequences since the user forgets to close the cabinet door or the user forgets to completely close the cabinet door can be avoided, and the problem disputing about the information of the person fetching the article at the next time since the cabinet door is not closed further can be avoided. The control system records the identity information of the person opening the cabinet door and the article fetching information at this time, so that the person and the time for depositing the article at this time are uniquely conformed.

Description

technical field [0001] The invention relates to an RFID intelligent cabinet, in particular to an intelligent cabinet capable of accurately identifying storage information of items in the cabinet. Background technique [0002] The current smart cabinet basically collects the item information based on the RFID electronic tag and its RFID reader for the items stored in the cabinet, and tracks the access of the item through the computer. The identification of the person who opens the cabinet door is mostly through password authentication, fingerprint and image recognition technology. These methods are only used to prevent the safety of the opening of the cabinet door, without considering the safety of the cabinet door after being opened, that is, the operator forgets to close the cabinet door or does not completely close the cabinet door after accessing the articles. Once the things are accessed by other people later, the control system will still record the identity informatio...

Problems solved by technology

These methods are only used to prevent the safety of the opening of the cabinet door, without considering the safety of the cabinet door after being opened, that is, the operator forgets to close the cabinet door or does not completely close the cabinet door after accessing the articles. Once the item is accessed by other personnel later, the control system will still record the identity information of the person who opened the cabinet door, which is inconsistent with the person who actually accessed the item, resulting in information confusion

Since this type of cabinet door uses a resistance (Ni) device, its purpose is only to prevent the door from being too violent when opening or closing. The advantage is that the door is opened and closed smoothly and the noise is low, but the disadvantage is that the cabinet door cannot be closed automatically.

However, through camera monitoring, it has the disadvantages of high cost, low image recognition, and easy to be blocked

[0003] In addition, due to the electromagnetic interference of the RFID tags stored in the smart cabinet, which affects the reading rate of the RFID reader, in order to solve this problem, most smart cabinets divide the space inside the cabinet into several "small cabinets" to avoid RFID tags. Interference between each other, but due to the uncertainty of the items stored in the smart cabinet, it is impossible to predict the space size of the "small cabinet". Once the space of the "small cabinet" is fixed, if it does not match the size of the items, it will cause the waste of space
