Problems solved by technology
[0003] In related technologies, the problem of blind spots is improved by adjusting the antenna standing wave ratio and antenna power, but the effect is not good. Due to the existence of blind spots, as long as there is no change in the position of the items in the cabinet, the electronic information of the items in the blind spots will be lost. It is difficult to be read, and the position of the dead zone is relatively fixed within a certain period of time

The present invention provides an intelligent cabinet for scanning, a scanning method, a scanning device and an intelligent cabinet. The intelligent cabinet for scanning comprises: a control module arranged in a cabinet body; a RFID scanning module arranged in the cabinet body, connected to the control module and configured to scan coding information of an electronic tag when a scanning instruction of the control module is received; at least one separator arranged in the cabinet body; and a movement module capable of being detachably installed at the at least one separator, or capable of beingin an integrated structure with the at least one separator, connected to the control module and configured to perform movement when a movement instruction of the control module is received to reducescanning dead zones of the electronic tag in the cabinet body. According to the technical scheme, a movement device is moved to change distribution of an electromagnetic field in a cabinet body to allow scanning blindness spots to be randomly changed so as to reduce scanning dead zones of the electronic tag in the cabinet body and improve a scanning efficiency of the electronic tag.
Description
technical field [0001] The present invention relates to the technical field of video recognition, in particular to a smart cabinet for scanning, a scanning method, a scanning device and a smart cabinet. Background technique [0002] In a closed space, especially a cabinet made of metal, an RFID (Radio Frequency Identification) scanning system is installed to realize the scanning identification and management of items in the cabinet. The wireless signal sent by the RFID antenna forms a closed loop in the cabinet, and the wireless The signal has deep fading in some areas of the cabinet. Due to the relatively stable environment in the cabinet, this deep fading lasts for a long time. For the electronic tags located in this area, the system can identify and read them slowly or even cannot read, these areas of missed reads are called dead zones, such as figure 1 As shown, the cabinet is equipped with an embedded system, which controls the switch of the cabinet door through finger...
