The RFID module 20 can be fixed on the inner surface of the cabinet 12, such as the side panel surface, the bottom surface 122, or the bottom surface of the top cabinet door, or it can be embedded in the cabinet 12, for example, embedded in the interlayer of the body wall of the cabinet 12 Here, the specific location can be determined according to the radio frequency signal returned by the antenna 18 to facilitate the reception. It should be noted that the positions of the RFID module 20 shown in the drawings are only to indicate the communication connection relationship between the RFID module 20 and the antenna 18, and not to limit the actual installation position of the RFID module 20. The above-mentioned antennas 18 may be the same type of antenna 18 or different types of antennas 18, as long as the RFID tag can be sensed. Frequency hopping scanning refers to sweeping from a certain frequency point in a certain frequency band, for example, sweeping at a certain frequency interval.
具体地,需要储藏的物品可以(可分为上层展示状态的物品和下层库存状态的物品)分别贴上相应的RFID标签后,放置在柜体12内储物空间的各空间区域内,以及放置在底板122上进行储藏。每一个RFID标签均唯一对应所贴附的物品。隔栏14上的天线18在所连接的RFID模块20驱动下,分别向两侧空间区域发射射频信号,以接收托板16上各物品的RFID标签反馈的射频信号,并传输给相应的RFID模块20。RFID模块20则可以根据接收到的射频信号读取到各物品对应的物品信息,如物品名称、生产日期、品类、单价等信息。期间,底板122上的天线18也可以在所连接的RFID模块20驱动下,分别向储物空间发射射频信号,以接收底板122上各物品的RFID标签反馈的射频信号,并传输给相应的RFID模块20。从而,RFID模块20可以更全面地获得底层物品的物品信息。Specifically, the items that need to be stored can be (divided into items in the upper display state and items in the lower inventory state) after being affixed with corresponding RFID tags, and placed in each space area of the storage space in the cabinet 12, and placed The storage is performed on the bottom plate 122. Each RFID tag uniquely corresponds to the attached item. The antenna 18 on the partition 14 is driven by the connected RFID module 20 to respectively transmit radio frequency signals to the space areas on both sides to receive the radio frequency signals fed back by the RFID tags of each item on the pallet 16, and transmit them to the corresponding RFID module 20. The RFID module 20 can read the item information corresponding to each item according to the received radio frequency signal, such as item name, production date, category, unit price and other information. During the period, the antenna 18 on the bottom plate 122 can also be driven by the connected RFID module 20 to respectively transmit radio frequency signals to the storage space to receive the radio frequency signals fed back by the RFID tags of each item on the bottom plate 122 and transmit them to the corresponding RFID Module 20. Therefore, the RFID module 20 can obtain the item information of the underlying item more comprehensively.
各个RFID模块20可以轮流在外部控制信号的触发下,例如运维人员手动触发提供的控制信号或者上位机输出的控制信号,开始进入工作状态,依次驱动自身所连接的各天线18进行跳频扫描,以采集射频信号覆盖范围内的各RFID标签所附物品的物品信息。例如在任一个RFID模块20工作时,其他RFID模块20保持待机。该工作状态的RFID模块20先驱动所连接的任一天线18在设定频段内,例如920MHZ到925MHZ频段内进行跳频扫描后,再驱动另一天线18在前述设定频段内进行跳频扫描,如此依次驱动各个天线18进行跳频扫描直到遍历该RFID模块20上所连接的所有天线18。在该RFID模块20遍历其上各个天线18扫频后,下一个RFID模块20开始进入工作状态,工作模式与前一工作结束后的RFID模块20相同。Each RFID module 20 can be triggered by an external control signal in turn, for example, the operation and maintenance personnel manually trigger the control signal provided or the control signal output by the upper computer, and start to enter the working state, and drive each antenna 18 connected to it in turn to perform frequency hopping scan , To collect the item information of the items attached to each RFID tag within the coverage of the radio frequency signal. For example, when any RFID module 20 is working, the other RFID modules 20 remain on standby. The RFID module 20 in this working state first drives any connected antenna 18 to perform a frequency hopping scan in the set frequency band, for example, 920MHZ to 925MHZ, and then drives another antenna 18 to perform a frequency hopping scan in the aforementioned set frequency band. In this way, each antenna 18 is sequentially driven to perform frequency hopping scanning until all the antennas 18 connected to the RFID module 20 are traversed. After the RFID module 20 traverses the frequency sweep of each antenna 18 on it, the next RFID module 20 starts to enter the working state, and the working mode is the same as that of the RFID module 20 after the previous working.
上述的储物装置100中,通过在储物装置内的隔栏14和底板122上合理的布设天线18,并且通过使各RFID模块20轮流投入工作,以使各RFID模块20驱动相应的天线18在设定频段内进行跳频扫描,从各RFID标签上采集各所述物品的物品信息。无需分别为各天线18配置单独的RFID模块20,大幅简化储物装置内的天线18布设架构,安装方便且识别盲区较小,大大降低了储物装置的运维成本。In the above-mentioned storage device 100, the antenna 18 is reasonably arranged on the partition 14 and the bottom plate 122 in the storage device, and each RFID module 20 is put into operation in turn, so that each RFID module 20 drives the corresponding antenna 18 Frequency hopping scan is performed in the set frequency band, and the item information of each said item is collected from each RFID tag. There is no need to configure a separate RFID module 20 for each antenna 18, which greatly simplifies the antenna 18 layout structure in the storage device, is convenient to install, and has a small identification blind area, which greatly reduces the operation and maintenance cost of the storage device.

S12,若当前工作状态的RFID模块20相应的天线18跳频扫描结束,则向下一个RFID模块20发送控制信号,以使下一个RFID模块20通过相应的天线18进行跳频扫描,采集各物品的物品信息。S12: If the frequency hopping scan of the antenna 18 corresponding to the RFID module 20 in the current working state ends, then a control signal is sent to the next RFID module 20, so that the next RFID module 20 performs a frequency hopping scan through the corresponding antenna 18, and collects each item Item information.
具体的,在当前处于工作状态的一个RFID模块20工作结束,也即该工作状态的RFID模块20已经依次驱动其上所有天线18进行了跳频扫描时,可以通过上位机或者储物装置100自带的控制系统,例如冰柜的总控制器向下一个RFID模块20发送控制信号,控制信号可以是但不限于时序电平信号。下一个RFID模块20开始在设定频段上,依次驱动其上各天线18进行了跳频扫描。下一个RFID模块20开始工作时,驱动其上任一天线18在920MHZ到925MHZ频段内进行跳频扫描。待该天线扫频接收,即驱动下一天线18在920MHZ到925MHZ频段内进行跳频扫描,如此,直至该下一个RFID模块20上的各个天线均完成跳频扫描即结束该下一个RFID模块20的工作。如此轮流控制各个RFID模块进出工作状态,即可实时通过各天线18跳频扫描时,各物品上RFID标签反馈的射频信号读取各物品的物品信息。Specifically, when the work of an RFID module 20 that is currently in working state ends, that is, the RFID module 20 in the working state has sequentially driven all antennas 18 on it to perform frequency hopping scanning, the upper computer or the storage device 100 can be used to automatically scan. The control system of the belt, for example, the general controller of the freezer sends a control signal to the next RFID module 20, and the control signal may be but not limited to a timing level signal. The next RFID module 20 starts at the set frequency band, and sequentially drives the antennas 18 on it to perform frequency hopping scanning. When the next RFID module 20 starts to work, any antenna 18 on it is driven to perform frequency hopping scanning in the frequency band of 920 MHz to 925 MHz. After the antenna is swept and received, the next antenna 18 is driven to perform frequency hopping scan in the frequency range of 920MHZ to 925MHZ. In this way, the next RFID module 20 is ended until each antenna on the next RFID module 20 completes the frequency hopping scan. work. In this way, each RFID module is controlled in and out of the working state in turn, and the item information of each item can be read by the radio frequency signal fed back by the RFID tag on each item when each antenna 18 is hopping and scanning in real time.

There is no need to configure a separate RFID module 20 for each antenna 18, which greatly simplifies the antenna 18 layout structure in the storage device, is convenient to install, and has a small identification blind area, which greatly reduces the operation and maintenance cost of the storage device.
在其中一个实施例中,上位机或者储物装置100自带的控制系统可以通过但不限于检测RFID模块20上的各天线18工作次数来判断该RFID模块是否已经工作结束,例如RFID模块20上的天线18总数量共有8个,则可以通过检测RFID模块20上是否已经有8个对应各天线18的端口依次工作结束,来判断该RFID模块是否已经工作结束。上位机或者储物装置100自带的控制系统还可以通过接收RFID模块在工作结束时对应反馈的电平信号,来确定该RFID模块以及工作结束。In one of the embodiments, the control system of the host computer or the storage device 100 can determine whether the RFID module has finished working by, but not limited to, detecting the working times of the antennas 18 on the RFID module 20, for example, on the RFID module 20. The total number of antennas 18 is 8, and it can be judged whether the RFID module has finished working by detecting whether there are already 8 ports on the RFID module 20 corresponding to each antenna 18 that have finished working in sequence.
