INFORMATION GATHERING SYSTEM AND INFORMATION GATHERING METHOD

PROBLEM TO BE SOLVED: To provide an information gathering system and information gathering method that can improve correctness of information be gathered.SOLUTION: An information gathering system according to an embodiment comprises: a transmission unit; a reception unit; and a processing unit. The transmission unit is configured to transmit a signal, and the reception unit is configured to receive the signal. The processing unit is configured to, upon calculating a distance between the transmission unit and the reception unit from intensity of the signal received by the reception unit, calculate the distance between the transmission unit and the reception unit as to the signal received for a first period of time from the intensity of respective signals received by the reception unit; and use an average distance having a plurality of calculated distances averaged as the distance between the transmission unit and the reception unit.SELECTED DRAWING: Figure 1 【課題】収集される情報の正確性を向上させることが可能な情報収集システムおよび情報収集方法を提供する。【解決手段】実施形態に係る情報収集システムは、発信部と、受信部と、処理部と、を含む。前記発信部は、信号を発する。前記受信部は、信号を受信する。前記処理部は、前記受信部が受信した前記信号の強度から前記発信部と前記受信部との間の距離を算出する際に、第１期間の間に受信された前記信号について、それぞれの前記信号の強度から前記発信部と前記受信部との間の距離を算出する。前記処理部は、算出された複数の前記距離を平均化した平均距離を、前記発信部と前記受信部との間の距離として用いる。【選択図】図１
