1. An automated work system comprising:
a surrounding environment measuring device that measures a surrounding environment of a work machine; and
an automated operation controlling device that controls an automated operation of the work machine,
wherein the automated operation controlling device includes:
a work status management section that selects, according to a work order in a work plan obtained, a work content from the work plan, creates an operation plan for the work machine on a work site based on the selected work content and information on the surrounding environment measured by the surrounding environment measuring device, and outputs a control signal to a vehicle body controller disposed in the work machine based on the created operation plan, so as to manage a work status of the work machine; and
an abnormal object detection section that detects an abnormal object present on the work site where the work plan is executed based on the information on the surrounding environment measured by the surrounding environment measuring device, and
when an abnormal object is detected by the abnormal object detection section on the work site, the work status management section determines whether or not an execution of the operation plan is to be hindered by the presence of the abnormal object, and when the execution of the operation plan is determined to be hindered by the presence of the abnormal object, further determines whether or not a hindered work is dividable into a work executed in a range including the abnormal object and a work executed in a range not including the abnormal object by comparing a work amount in the range not including the abnormal object with a preliminarily determined threshold value, and when the hindered work is determined to be dividable, creates the operation plan for the range not including the abnormal object.
