摘要： A work machine management system includes: a position detector detecting a position of a work machine traveling on a travel route; a non-contact sensor detecting an object in a vicinity of the travel route in a non-contact manner; map data to accumulate information on existence and a position of the object in the travel route based on detection data obtained by the position detector and detection data obtained by the non-contact sensor; a travel route generator generating the travel route where the work machine travels; and an identifying unit to identify an area or a travel route having low perfection of map data of a travel route where the work machine travels. The travel route generator generates a travel route so as to cause the work machine not to pass the area or the travel route having the low perfection of the map data.

摘要： A work machine control system is configured to control a work machine that travels on a travel route and includes a position detection unit, a non-contact sensor, and a control unit. The position detection unit detects a position of the work machine. The non-contact sensor detects a position of an object around the work machine. The control unit extracts information on an object to be detected from a detection result of the position detection unit and a detection result of the non-contact sensor, and excludes the information on an object to be detected inside a mask region that is set so as to include a terrain change portion that is a portion in which a terrain changes by use of a machine among portions around the travel route.

摘要： A work machine control system is configured to control a work machine that travels in an operation region and includes a position detection unit, a non-contact sensor, and a control unit. The position detection unit detects a position of the work machine. The non-contact sensor detects a position of an object around the work machine. The control unit extracts information on an object to be detected from a detection result of the position detection unit and a detection result of the non-contact sensor, and excludes moving object information that is information on an object to be detected regarding a moving object that moves in the operation region.
