Abstract
(EN)
The present invention performs distance measurement in which influence of fading is reduced while reception intensity is utilized. This distance measuring device is provided with a first communication unit and a control unit. The first communication unit receives signals, which are sustained for a predetermined period of time, a predetermined number of times. The control unit obtains the maximum value of the reception intensity of the signals received, each time, by the first communication unit within the predetermined period of time, and obtains variation of a predetermined number of the maximum values. The control unit determines that, when the variation is equal to or greater than a threshold, the position of an emission source which emits signal is away from the first communication unit by a predetermined distance or more, and determines that, when the variation is lower than the threshold, the position of the emission source from the first communication unit is closer than the predetermined distance.

La présente invention réalise une mesure de distance dans laquelle l'influence de l'évanouissement est réduite lorsque l'intensité de réception est utilisée. Ce dispositif de mesure de distance est pourvu d'une première unité de communication et d'une unité de commande. La première unité de communication reçoit des signaux, qui sont maintenus pendant une période de temps prédéterminée, un nombre prédéterminé de fois. L'unité de commande obtient la valeur maximale de l'intensité de réception des signaux reçus, chaque fois, par la première unité de communication dans la période de temps prédéterminée, et obtient une variation d'un nombre prédéterminé de valeurs maximales. L'unité de commande détermine que, lorsque la variation est égale ou supérieure à un seuil, la position d'une source d'émission qui émet un signal est séparée de la première unité de communication d'une distance prédéterminée ou plus, et détermine que, lorsque la variation est inférieure au seuil, la position de la source d'émission par rapport à la première unité de communication est plus proche de la distance prédéterminée.

受信強度を利用しつつも、フェージングの影響を低減した測距が行われる。測距装置は、第1通信部と、制御部とを備える。第1通信部は、所定期間において持続する信号を、所定数の回数によって受信する。制御部は、第1通信部が受信した信号の受信強度の、所定期間内における最大値を受信した回数毎に求め、所定数の最大値のばらつきを求める。制御部は、ばらつきが閾値以上であれば、信号を発信する発信源の位置が第1通信部から所定距離以上で離れていると判定し、ばらつきが閾値未満であれば、発信源の位置が第1通信部から所定距離よりも近い、と判定する。
