Title:
無線通信モジュールの取付構造、無線通信モジュールの設置方法及び状態量計測システム
Document Type and Number:
Japanese Patent JP7132009
Kind Code:
B2
Abstract:
To acquire a state quantity in a concrete structure more easily by using a wireless communication module.SOLUTION: An RFID tag 1 provided on a concrete structure 8 and transmitting the state quantity of the concrete structure 8 measured by a sensor 4 by wireless communication is connected to the sensor 4 and is placed in the concrete structure 8 in a state where the entire portion is covered with a resin 3 and a part of the resin 3 is exposed. Furthermore, the exposed portion where the resin 3 is exposed and the surface of the concrete structure 8 are arranged to be flush. Since the transmission radio wave from the RFID tag 1 is transmitted without passing through the concrete structure 8, the transmission radio wave is suppressed from being attenuated by the concrete structure 8, and the transmittable distance can be extended correspondingly. Therefore, even at a position farther from the concrete structure 8, the transmission radio wave of the RFID tag 1 can be easily received by a reader/writer or the like.SELECTED DRAWING: Figure 1
