PROBLEM TO BE SOLVED: To provide an area data providing system, an area data providing method and a master machine that can indicate the range of an area only available during a specified period of time, in other words, the range of a quasi-static area.SOLUTION: A master machine 110 and a plurality of slave machines 120 are placed on the borderline of a designated area 101 in different positions from each other. Each of the slave machines 120 calculates a slave machine coordinate value by positioning a placed position thereof and sends the calculated slave machine coordinate value. The master machine 110 calculates a master machine coordinate value by positioning a placed position thereof, receives a plurality of slave machine coordinate values sent from the plurality of slave machines, calculates the range of the designated area 101 using the master machine coordinate value and the plurality of slave machine coordinate values, and sends area data indicating the range of the designated area 101.SELECTED DRAWING: Figure 1
【課題】特定の期間だけ有効となる区域の範囲、すなわち、準静的な区域の範囲を通知できる区域データ提供システム、区域データ提供方法および親機を提供する。【解決手段】親機110および複数の子機120が、指定区域101の境の互いに異なる位置に配置される。それぞれの子機120は、配置された位置を測位することによって子機座標値を算出し、算出された子機座標値を送信する。前記親機110は、配置された位置を測位することによって親機座標値を算出し、前記複数の子機座標値から送信される複数の子機座標値を受信し、前記親機座標値と前記複数の子機座標値とを用いて前記指定区域101の範囲を算出し、前記指定区域101の範囲を示す区域データを送信する。【選択図】図1
