CONVEYANCE SYSTEM

To provide a conveyance vehicle system capable of appropriately controlling a travel of the conveyance vehicle based on vibration generated during the travel without human intervention.SOLUTION: A conveyance vehicle system 1 includes: a travel control part 72 that causes an overhead conveyance vehicle 6 to travel according to a set speed set for each section of a travel path 4; an acquisition part 73 that acquires vibration information regarding vibration generated in the overhead conveyance vehicle 6 traveling on the travel path 4; and a storage part 76 that stores traveling path information in which vibration information is associated with position information of the overhead conveyance vehicle 6 when vibration occurs. The travel control part 72 determines whether or not a speed limit is necessary for each section 4B based on travel path information stored in the storage part 76, and determines the set speed set for the section 4B in which it has been determined that the speed limit is necessary to reset to a new speed value lower than a current speed value.SELECTED DRAWING: Figure 2 【課題】人の手を介することなく、走行時に生じる振動に基づいた搬送車の適切な走行制御が可能になる搬送車システムを提供する。【解決手段】搬送車システム１は、走行路４の区間ごとに設定された設定速度に従って天井搬送車６を走行させる走行制御部７２と、走行路４を走行する天井搬送車６に発生する振動に関する振動情報を取得する取得部７３と、振動情報と振動が発生した時の天井搬送車６の位置情報とを関連付けた走行路情報を記憶する記憶部７６と、を備える。走行制御部７２は、記憶部７６に記憶された走行路情報に基づいて区間４Ｂごとに速度制限の要否を判定し、速度制限が必要と判定された区間４Ｂに設定されている設定速度を、現在の速度値よりも低い新たな速度値に再設定する。【選択図】図２
