Description

The present invention relates to a system using a pile with a built-in RF tag, which is a pile with a built-in RF tag.

It has long been considered to incorporate RF tags into piles driven into the ground. If different data is stored in each RF tag built into the pile, even if the upper surface of the pile cannot be seen due to overgrowth of weeds, the information related to the point where the pile was driven can be obtained from the data read from the RF tag wirelessly. Obtainable.

Since the fields of use of piles with built-in RF tags, which are piles with built-in RF tags, are diverse, such as the field of land surveying, the field of automobiles, and the field of buried object management, it is considered that piles with built-in RF tags will be installed in various fields of use. On the terminal device side that uses the RF tag built-in pile, a mechanism that can specify the field of use of the RF tag built-in pile detected by the terminal device is required.

In the system disclosed in Patent Document 1, the tag identifier (tag identification) of the RF tag built in the RF tag built-in pile (marker) can be specified so that the field of use of the RF tag built-in pile detected by the terminal device can be specified. Information), a management server that stores the position data related to the burial point of the pile with built-in RF tag and the service information related to the position data is provided. The terminal device having a mobile communication function notifies this management server of the tag identifier read from the RF tag, and provides service information related to the burial point of the RF tag built-in pile containing the RF tag read from the tag identifier. Obtained from this management server.

However, when stakes with built-in RF tags in various fields of use are installed in urban areas, there is a problem that the terminal device detects stakes with built-in RF tags in unintended fields of use. It is desirable to construct the system on the assumption that the terminal device will detect the pile with built-in RF tag.

In the distribution / logistics industry, the tag data stored in the RF tag is made unique by the standard such as Non-Patent Document 1 so that it can be judged whether the RF tag that reads the data is the RF tag corresponding to the own system. I am trying to. However, the data format standardized by standards such as Non-Patent Document 1 is a data format suitable for individually identifying each item, and it is not always necessary to identify each item individually. Not suitable for stakes with built-in tags. This is because if the position data related to the burial point of the RF tag built-in pile is stored in the RF tag built in the RF tag built-in pile, even if the RF tag built-in pile cannot be individually identified, it can be read from the RF tag. This is because the terminal device can execute the processing related to the field of use supported by the terminal device by using the position data.
