PROBLEM TO BE SOLVED: To provide a cargo work vehicle calling device, which allows a cargo work vehicle to switch between an unmanned operation mode and a manned operation mode, and allocates cargo work which brings about less fatigue when an operator feels fatigued very much in the manned operation mode.SOLUTION: The cargo work vehicle calling device comprises: a fatigue degree determining portion that determines whether or not an operator feels fatigued; and a cargo work fatigue increase determining portion that calculates the sum of a determined result by the fatigue degree determining portion when the operator is executing a manned operation mode and an increase of fatigue degrees caused by cargo work operation allocated to the operator when the operator is executing the manned operation mode, and determines whether or not the sum is above a second threshold indicating prescribed fatigue degrees smaller than a first threshold indicating prescribed fatigue degrees as a reference for the operator to take a break; and an instruction generating portion that when the cargo work fatigue degree increase determining portion determines that the sum is above the second threshold, generates an instruction for switching an operation state from in the manned operation mode into in the unmanned operation mode and outputs the instruction to a cargo work vehicle.SELECTED DRAWING: Figure 2
【課題】無人運転と有人運転とを切り替えることが可能とし、有人運転中の疲労の多いときに疲労度の小さい内容の荷役作業を割り当てる。【解決手段】運転者が疲労しているか否かを判定する疲労度判定部と、前記運転者が有人運転を行っているときの前記疲労度判定部による判定結果と、前記運転者が有人運転を行っているときに前記運転者に割り当てられている荷役作業による疲労度の増加分との総和を算出し、前記総和が休憩に入る基準となる所定の疲労度を示す第1閾値よりも小さい所定の疲労度を示す第2閾値以上であるか否かを判定する荷役疲労増加判定部と、前記荷役疲労増加判定部が前記総和が前記第2閾値以上であると判定した場合に、前記有人運転から無人運転の運転状態へ切り替える指示を生成し、荷役車両へ出力する指示生成部と、を備えることを特徴とする荷役車両呼出装置。【選択図】図2
