POSITION ESTIMATION DEVICE, POSITION ESTIMATION PROGRAM, MONITORING DEVICE, AND STATE MONITORING SYSTEM
PROBLEM TO BE SOLVED: To allow the arrangement of each of sensor units (rubber cones) to be identified even if the sensor units are arranged in any order.SOLUTION: A position estimation device according to the present invention estimates the position of each of a plurality of radio devices that are arranged with some space from each other and perform multi-hop communication with each other. The position estimation device comprises: radio wave reception intensity retention means for retaining radio wave reception intensity between each of the radio devices and peripheral radio devices for each radio device; and arrangement estimation means for estimating arrangement of the radio devices on the basis of plural pieces of assumed arrangement information assuming the arrangement of the radio devices and the radio wave reception intensity of each radio device.SELECTED DRAWING: Figure 1
【課題】センサユニット（ラバーコーン）を任意の順番で配置した場合でも、各センサユニットの配列を特定できるようにする。【解決手段】本発明に係る位置推定装置は、それぞれ間隔をあけて配列され、互いにマルチホップ通信を行なう複数の無線機のそれぞれの位置を推定する位置推定装置において、複数の無線機のそれぞれにおける周辺無線機との間の電波受信強度を無線機毎に保持する電波受信強度保持手段と、複数の無線機の配列を仮定した複数の仮定配列情報と、各無線機の電波受信強度とに基づいて、複数の無線機の配列を推定する配列推定手段とを備える。【選択図】 図１
