  Then, as shown in FIG. 2, the RFID (Radio Frequency Identification) tag 2 records data in a tag of about several centimeters in size, and communicates with the portable information processing apparatus 3 by radio waves or electromagnetic waves. The communication distance is about several mm to several m. There are various standards depending on the difference in operating frequency, etc., and any of them may be used, and NFC (Near Field Communication) tag is a kind of RFID tag. The RFID tag 2 is a passive type that operates with an external radio wave or electromagnetic wave as an energy source, but an active type incorporating a battery may be used as needed.

  For this reason, even if the RFID tag 2 is installed in a place where it is difficult for people to come close, such as in a bridge or a tunnel, communication is possible between the RFID tag 2 and the portable information processing apparatus 3.

  Here, any portable information processing apparatus 3 can be used as long as it has an RFID reading function and a function capable of connecting to the Internet, such as a mobile phone, a smartphone, and a tablet. Of course, a dedicated terminal having an RFID reading function and an internet browsing function can also be used.

An example of a screen in a state in which the URL 21 is accessed by the portable information processing device 3 of FIG. This screen is for inputting an ID 61 and a password 62 registered in advance. Unless these are input, the information on the structure corresponding to the URL 21 can not be browsed.

  When the ID 61 and the password 62 are input in the screen of FIG. 6 and the login button 63 is pressed, the screen shifts to a screen showing object information of the structure 1. An example of this screen is shown in FIG. The screen shown in FIG. 7 is a screen showing object information of “* ※※ Ohashi” 71, which is an example of a bridge, corresponding to various buttons such as structure outline 72, 73 for submission, 74 for preservation, and repair history 75. Screen information is switched. FIG. 7 is a screen of the structure outline 72, in which predetermined information such as structure name, year of completion, structure number, location, photograph, map, drawing, etc. can be viewed.
