Abstract

The present disclosure discloses an item monitoring method, terminal and system. The item monitoring method includes: scanning a radio frequency identification tag of an item within a preset range according to a preset scanning period using radio frequency identification technology, and acquiring item information in the radio frequency identification tag; determining whether the item corresponding to the item information belongs to an item scope covered by the preset range; and outputting first prompt information in response to determining that the item corresponding to the item information does not belong to the item scope covered by the preset range.

First claim

I claim:

1. An item monitoring method performed by an item monitoring terminal fixed in a preset range, wherein the item monitoring terminal comprises a scanning identification circuit, a processing circuit connected to the scanning identification circuit, and an output circuit connected to the processing circuit, and the scanning identification circuit comprises a RFID reader and writer having an operating frequency band of 840-960 MHz connected to the processor circuit and a UHF circularly polarized narrow beam antenna connected to the RFID reader and writer,
the method comprising:
scanning, by the scanning identification circuit, a radio frequency identification tag of an item within the preset range according to a preset scanning period using radio frequency identification technology, and acquiring item information in the radio frequency identification tag;
determining, by the processing circuit, whether the item corresponding to the item information belongs to an item scope covered by the preset range; and
outputting, by the output circuit, first prompt information indicating that the item is misplaced, in response to determining that the item corresponding to the item information does not belong to the item scope covered by the preset range,
the method further comprising:
acquiring tag information in the radio frequency identification tag;
determining, according to the tag information, whether the item corresponding to the tag information is a new item;
storing, in response to determining that the item corresponding to the tag information is a new item, item information and tag information of the new item, and uploading the item information and the tag information of the new item to a server;
determining whether the new item belongs to the item scope covered by the preset range;
outputting second prompt information in response to determining that the new item belongs to the item scope covered by the preset range; and
outputting the first prompt information in response to determining that the new item does not belong to the item scope covered by the preset range,
wherein storing, in response to determining that the item corresponding to the tag information is a new item, item information and tag information of the new item, and uploading the item information and the tag information of the new item to a server comprises:
storing item information and tag information of the new item in an item storage list if the new item is detected by scanning in a next scanning period, which indicates that the new item has been placed within the preset range monitored by the item monitoring terminal;
storing item information and tag information of the new item in an illegal item list in response to determining that the new item does not belong to the item scope covered by the preset range; and
uploading the item storage list and the illegal item list to the server when a connection is established with the server,

wherein the preset scanning period is a time required for the item monitoring terminal to scan all items within the preset range, and if the item monitoring terminal reads a radio frequency identification tag by scanning during the preset scanning period, it is determined that an item corresponding to the radio frequency identification tag is placed within the preset range monitored by the item monitoring terminal.

2. The method according to claim 1 , further comprising:
acquiring an item pick-up task list;
scanning radio frequency identification tags of items within the preset range according to the preset scanning period and generating an item storage list;
comparing an item storage list which is currently obtained by scanning with an item storage list which is previously obtained by scanning to obtain different item information;
determining whether items corresponding to the different item information belong to the item pick-up task list;
outputting third prompt information in response to determining that the items corresponding to the different item information belong to the item pick-up task list; and
outputting fourth prompt information in response to determining that the items corresponding to the different item information do not belong to the item pick-up task list.

3. The method according to claim 2 , further comprising:
determining whether a number of items corresponding to the different item information is consistent with a number of corresponding items to be picked up in the item pick-up task list, and
outputting fifth prompt information in response to determining that the number of items corresponding to the different item information is not consistent with the number of the corresponding items to be picked up in the item pick-up task list.

4. The method according to claim 2 , further comprising:
displaying the item pick-up task list and the different item information.

5. An item monitoring terminal, comprising:
a scanning identification circuit configured to scan a radio frequency identification tag of an item within a preset range according to a preset scanning period using radio frequency identification technology, and acquire item information in the radio frequency identification tag;
a processing circuit configured to determine whether the item corresponding to the item information belongs to an item scope covered by the preset range; and
an output circuit configured to output first prompt information indicating that the item is misplaced, if the item corresponding to the item information does not belong to the item scope covered by the preset range,
wherein the item monitoring terminal is fixed in the preset range, and
wherein the item monitoring terminal comprises a scanning identification circuit, a processing circuit connected to the scanning identification circuit, and an output circuit connected to the processing circuit, and the scanning identification circuit comprises a RFID reader and writer having an operating frequency band of 840-960 MHz connected to the processor circuit and a UHF circularly polarized narrow beam antenna connected to the RFID reader and writer,
wherein the scanning identification circuit is further configured to acquire tag information in the radio frequency identification tag; the processing circuit is further configured to determine whether the item corresponding to the tag information is a new item according to the tag information; and the terminal further comprises a memory configured to store item information and tag information of the new item if the item corresponding to the tag information is a new item and a transmitting circuit configured to upload the item information and the tag information of the new item to a server;
wherein the processing circuit is further configured to determine whether the new item belongs to the item scope covered by the preset range; and the output circuit is further configured to output second prompt information if the new item belongs to the item scope covered by the preset range and output the first prompt information if the new item does not belong to the item scope covered by the preset range;
wherein the memory is configured to store item information and tag information of the new item in an item storage list if the new item is detected by scanning in a next scanning period, which indicates that the new item has been placed within the preset range monitored by the item monitoring terminal, and store item information and tag information of the new item in an illegal item list in response to determining that the new item does not belong to the item scope covered by the preset range; and the transmitting circuit is configured to upload the item storage list and the illegal item list to the server when a connection is established with the server; and
wherein the preset scanning period is a tim
