Further, when the cargo position is a position covering the first position and the second position, the orientation of the first antenna assembly and the second antenna assembly is not required to be changed, and only the orientation of the third antenna assembly is required to be controlled and adjusted downwards, so that the cargo tag identification range of the first position and the second position is increased.
Further, when the object position is to cover all positions, i.e. the number of cargoes is large, or the cargo volume is large, the antenna assembly of each position needs to identify the cargo tag of its corresponding position, so the orientation of the first antenna assembly, the second antenna assembly and the third antenna assembly needs to be kept unchanged.
Step S104: and after the circular polarized antenna assembly is controlled, scanning the label of the goods according to the quantity of the goods.
In this embodiment, according to the number of goods obtained by the preliminary scanning, the labels of the goods are scanned, so that the number of labels obtained by the scanning can be further obtained, and when the number of goods is different from the number of labels, a goods identification error warning is generated to warn an operator.
Step S105: and controlling all circularly polarized antenna assemblies to restore to the initial orientation until all the labels of the goods are scanned, and controlling the rotary type side-by-side doors to open.
The implementation of the above embodiment has the following effects:
according to the embodiment of the invention, the channel type radio frequency door is controlled to realize the RFID tag information of the small-area ultrahigh frequency radio frequency identification goods, meanwhile, the occurrence of the situation of identification dead zones can be avoided under the condition of different goods positions, the orientation of the circularly polarized antenna is controlled, the accurate identification of the quantity and the positions of the goods is realized, and the accuracy and the efficiency of the radio frequency identification of the goods tags are improved.
