To solve the problems of the conventional art, in other words, to provide an automatic operation construction machine system that can prevent contact between automatic operation construction machines and continue to operate them even when positioning is temporarily impossible, and an automatic operation construction machine control method using this.SOLUTION: An automatic operation construction machine control system of the present invention is a system for controlling two or more automatic operation construction machines congested in the same construction area, and includes control means, positioning means, operating state measuring means, and transmitting/receiving means. When the positioning means does not acquire its own position beyond the first threshold time, the control means of the automatic operation construction machine related to the positioning means determines that the automatic operation construction machine is in a "provisional abnormal situation", and runs the automatic operation construction machine while maintaining the moving speed and the moving direction when determined that it is in the provisional abnormal situation.SELECTED DRAWING: Figure 2 【課題】本願発明の課題は、従来技術が抱える問題を解決することであり、すなわち一時的に測位できない状況になったときであっても、自動運転式建設機械どうしの接触を防ぎそれぞれ継続して稼働することができる自動運転式建設機械システムと、これを用いた自動運転式建設機械の制御方法を提供することである。【解決手段】本願発明の自動運転式建設機械制御システムは、同一の施工領域で輻輳する２以上の自動運転式建設機械を制御するシステムであって、制御手段と測位手段、動作状態計測手段、送受信手段を備えたものである。第１閾値時間を超えて測位手段が自機位置を取得しないとき、その測位手段に係る自動運転式建設機械の制御手段は、その自動運転式建設機械を「暫定異常事態」として判断するとともに、暫定異常事態と判断したときの移動速度及び移動方向を維持したまま自動運転式建設機械を走行させる。【選択図】図２
