Storage box state determination system

A storage box state identification system comprising:

• a storage that stores an identification information management table in which a plurality of pieces of tag identification information for identifying wireless tags are associated with storage box identification information for identifying a storage box for storing a load, and a state management table in which an empty state where no load is stored in the storage box and a storing state where a load is stored in the storage box are associated with a number of pieces of the tag identification information;
• an information acquisition part that acquires the tag identification information of a plurality of wireless tags via an antenna that receives a radio wave outputted from the wireless tags attached to the storage box in a cargo bed of a vehicle;
• a number identification part that identifies storage box identification information corresponding to the tag identification information acquired by the information acquisition part by referencing the identification information management table, and identifies the number of pieces of tag identification information acquired corresponding to the identified storage box identification information;
• and
• a state identification part that identifies, by referencing the state management table, whether a state of a storage box indicated by the storage box identification information corresponding to the acquired tag identification information is the empty state or the storing state on a basis of the number of acquisitions identified by the number identification part,
• wherein the number of pieces of the tag identification information associated with the empty state of the state management table is less than the number of pieces of the tag identification information associated with the storing state.
