PROBLEM TO BE SOLVED: To provide a radio terminal 2 allowing a management server 3 to grasp parking position information of a vehicle 1.SOLUTION: A radio terminal 2 comprises: a radio unit 24; a sensor unit 21 which measures a vehicle position; a power supply unit 22 which receives electric power supply from an external power supply; a battery unit 221; a residual capacity determining unit 205 which determines whether the residual capacity of the battery unit 221 exceeds a preset first capacitance value; and a position information notifying unit 208 which transmits the vehicle position information to a management server 3 at preset first transmission intervals when the residual capacity determining unit 205 determines that the residual capacity of the battery unit 221 exceeds the first capacitance value, and notifies the management server 3 of the vehicle position information at second transmission intervals shorter than the first transmission intervals when the residual capacity determining unit 205 determines that the residual capacity of the battery unit 221 is less than or equal to the first capacitance value.SELECTED DRAWING: Figure 1
【課題】車両1の駐車位置情報を管理サーバ3で把握することを可能にする無線端末2を提供すること。【解決手段】無線部24と、車両位置を測定するセンサ部21と、外部電源から電力の供給を受ける電源部22と、バッテリー部221と、バッテリー部221の残容量が予め設定された第1の容量値を上回るか否かを判定する残容量判定部205と、残容量判定部205によりバッテリー部221の残容量が第1の容量値を上回ると判定されるとき予め設定された第1の送信間隔で車両位置情報を管理サーバ3に送信し、残容量判定部205によりバッテリー部221の残容量が第1の容量値以下の場合、第1の送信間隔よりも短い第2の送信間隔で車両位置情報を管理サーバ3に通知する位置情報通知部208と、を備える無線端末2。【選択図】図1
