An automated operation controllerof an automated work systemincludes: a work status management sectionthat selects a work content according to a work DBthat records a work plan for a hydraulic excavatorand a work order in the work plan, creates an operation plan based on the selected work content and information on the surrounding environment measured by laser scanners, and outputs a control signal to a vehicle body controllerbased on the operation plan; and an abnormal object detection sectionthat detects an abnormal object present on a work site based on the information on the surrounding environment measured by the laser scanners. When the execution of the operation plan is determined to be hindered by the presence of the abnormal object, the work status management sectionselects another work content from the work plan.

Automated work system

A working status indicating a status related to the present work of a hydraulic excavatoris determined on the basis of operation signals output from a control lever, posture information output from inertial measuring devicesto, load information output from pressure sensorsand, and a work area set by a display input device, an operation form indicating contents of an operation in operation correction control of a front work implementis decided from a plurality of operation forms set in advance, according to the determined working status, and the operation correction control is performed such that the front work implement moves according to the operation form. Thus, an appropriate assisting operation can be performed in machine control, so that the work accuracy can be improved.

Work machine

A construction machine includes a posture sensor provided on a front member of a front work implement. An external environment recognition device detects an object around a main body, and a controller calculates a dead angle range from a recognition range of the external environment recognition device. An assumed movement range in which a moving body is assumed to exist in the dead angle range in a period of time determined in advance is calculated; and a movable range within which the front work implement is movable in a period of time determined in advance is calculated on the basis of the posture information detected by the posture sensor. Preventative control is then performed for preventing contact between the moving body and the front work implement on the basis of the assumed movement range of the moving body and the movable range of the front work implement.

Construction machine

In a case that a change instruction to instruct to change a work area Ato a requested work area Ais input, whether or not change of the work area Ato the requested work area Ais possible is judged on the basis of the work area A, location information of a machine main body configured by an upper swing structureand a lower track structure, and posture information of a work device, and the work area Ais overwritten with the requested work area Ato change the work area in an only case that it is judged that change is possible. This can suppress interference between plural work machines.
