IN-TANK SENSOR POSITION ESTIMATION SYSTEM AND IN-TANK SENSOR POSITION ESTIMATION METHOD

PROBLEM TO BE SOLVED: To provide an in-tank sensor position estimation system and an in-tank sensor position estimation method capable of highly accurately grasping a position of a sensor in a tank with a simple configuration.SOLUTION: An in-tank sensor position estimation system has sensors 6 each provided in a content (coal) 4 of a reservoir facility (coal reservoir facility) 1 storing the content 4 in a tank (reservoir tank) 2 and including a transmission unit which transmits measurement information as a wireless signal, and comprises three or more fixed stations 7A, 7B, 7C, and 7D provided in the reservoir facility 1 and each including a function to receive the wireless signal, the system estimating a position of each sensor 6 in the tank (reservoir tank) 2 on the basis of wireless signal propagation time between the sensor 6 and each of the fixed stations 7A, 7B, 7C, and 7D.SELECTED DRAWING: Figure 1 【課題】簡単な構成で槽内におけるセンサの位置を精度良く把握し得る槽内のセンサ位置推定システム及び推定方法を提供する。【解決手段】槽（貯留槽）２内に内容物（石炭）４を貯留する貯留設備（石炭貯留設備）１の内容物４中に、測定情報を無線信号として送信する送信部を備えたセンサ６を埋没させると共に、貯留設備１に無線信号を受信する機能を有する三機以上の固定局７Ａ，７Ｂ，７Ｃ，７Ｄを備え、センサ６と固定局７Ａ，７Ｂ，７Ｃ，７Ｄの間における無線信号の伝播時間を基に、槽（貯留槽）２内におけるセンサ６の位置を推定する。【選択図】図１
