In this case, the readers 11, 12, and 13 for reading the asset of the region 51 to which the specific department belongs read the department information of the tag 21 attached to the specific asset of the department, Measure the signal strength. As described above, each of the readers 11, 12, and 13 transmits the department information of the tag 21 read by itself and the radio signal intensity information detected for the tag to the asset position monitoring system 100 using the wireless recognition tag . Asset location system 100 using wireless recognition tag calculates the positional coordinates of the tag within the zone 51 of the department from the signal strength information measured by each reader 11, 12, 13. In order to accurately calculate the position, it is preferable that each reader is disposed at three or more positions at least in each region when the tag information is grasped in a specific region.

The asset location inspection system 100 using the wireless recognition tag can retain the electronic map data for the building of the company. That is, an electronic map including various information such as a space occupied by each department, a passage, and the like may be held on the database 170 (see Fig. 4). Asset location inspection system 100 using the wireless recognition tag uses the position coordinates calculated for each tag and the electronic map data in the building to determine the location of the tag 21, It is possible to judge to which department of the department the location is located (location department information), and the department information read from the tag 21 as described above, that is, the department information having the asset to which the tag 21 is attached (Tag department information) and the location department information to determine whether the asset has been moved to another department.

Although only one tag 21 is shown in FIG. 1 for the sake of convenience, the above-described operations are also performed for the tags attached to the plurality of assets located in the department area 51, respectively. In addition, each of the readers 11, 12, and 13 is located in each department area at the time of actual asset location inspection, and transmits the information (tag department information and signal strength information) as described above to the asset location inspection system 100 using a wireless recognition tag.
