Abstract
Provides asset position detecting apparatus and methods for determining the correspondence relation between an asset attached to an RFID tag and the position in which the asset is located in a predetermined space range. An example apparatus includes: a movable RFID reader movable in the space range, for detecting whether the asset exists in its read range, and reading the RFID tag attached to the asset within its read range, to obtain the specific identification of the detected asset; and position determining means for determining the position where the reader is located, wherein, when said RFID reader detects that said asset exists in its read range during its movement, the obtained identification of the asset and the current position of the RFID reader are associatively stored in a database, so as to obtain the information regarding the position of said asset.
