A reproduction device includes an acquisition unit, a reception unit, a reproduction unit, and an estimation unit. The acquisition unit acquires log information of a work machine, which is associated with time. The reception unit receives a reproduction instruction for an operation of the work machine. The reproduction unit reproduces the operation of the work machine, by sequentially applying angle information of the work machine that is included in the log information, to a work machine model in a case of receiving the reproduction instruction. The estimation unit estimates a work content of the work machine at each time, based on the log information.

A first processor acquires data indicative of a position of a predetermined reference point included in a conveyance vehicle. The first processor acquires data indicative of a position of a rotation center of a rotating body of a work machine. The first processor acquires data indicative of a position of a blade tip of a work implement of the work machine. The first processor determines a target rotation angle of the rotating body from a straight line connecting the position of the rotation center of the rotating body and the position of the reference point of the conveyance vehicle, and a current position of the blade tip of the work implement. The first processor controls the rotating body to rotate according to the target rotation angle.

A data collection device for work machines collects data from a component mounted on a work machine. The data collection device includes a collection unit that collects the data from the component via a vehicle-mounted network, and a conversion unit that generates a unified data object by converting the collected data into a predetermined format, and a data transmission unit that transmits the unified data object to the outside.

A display system of a work machine includes a storage that stores time-series work machine motion information including motion information of the work machine, a motion image generator that generates a motion image of the work machine based on the work machine motion information, and a display that shows the motion image.

This invention is a continuum of enabling technology applying prior patent applications to create and then sustain a planetary heavy construction, soil and water mining and refining using a nuclear power appliances infrastructure. The methods used within this invention provide capabilities to build a sustainable support environment for earth-like habitable complexes that will include buildings and maintenance facilities, living spaces, and office spaces focused on full scale commercial mining operations for He3, H.sub.2O and other strategic minerals and raw building materials.

A method for a zone passage control system for an underground worksite having a plurality of operation zones for autonomously operating mobile vehicle operations includes the steps of associating a first passage control unit with a first zone and a second zone, detecting state parameter information of the first zone and the second zone, merging the first zone and the second zone into a fusion zone on the basis of the state parameter information of the first zone and the second zone, and adapting the zone passage control system to allow a first autonomously operating mobile vehicle to pass the first passage control unit in the fusion zone without interrupting operation of a second autonomously operating mobile vehicle in the first zone and/or the second zone.

A work vehicle includes a working device which is configured to excavate and unload soil, a load meter which is configured to measure weight of the soil loaded by the working device, a transport vehicle specifier which is configured to specify a transport vehicle to be loaded with the soil, a vehicle weight acquirer which is configured to acquire vehicle weight information on loadable weight of the transport vehicle, a load weight calculator which calculates load weight of the soil loaded on the transport vehicle, according to the weight measured by the load meter, and an output unit which is configured to output information on a remaining loading capacity of the transport vehicle obtained from the vehicle weight information and the load weight.

A reception unit receives, from an execution information terminal, an access request made by an execution manager to an operation management system. When the reception unit receives the access request, a determination unit determines whether the execution manager who has made the access request satisfies a disclosure condition stored in a first storage unit. When the determination unit determines that the execution manager who has made the access request satisfies the disclosure condition, a permission unit permits disclosure of the operational information to the execution manager.

Embodiments of the present disclosure relate to a method and apparatus for selecting a target excavating point. The method includes: acquiring a height map of a material pile; discretizing the height map to obtain an excavating point set; acquiring an excavating trajectory set of an excavating point in the excavating point set; and selecting a target excavating point based on the excavating trajectory set of the excavating point in the excavating point set.

Systems and methods are disclosed for management of a fleet of machines operating in a construction and/or civil engineering project. Telematics data is received from first and second machines at regular intervals. Positional and temporal proximity is determined between the first and second machines based at least in part on an analysis of the telematics data, indicating for example that the first machine is within a predetermined maximum distance of the second machine for at least a predetermined minimum duration. If there is positional and temporal proximity, work cycle data is received from the machines and is correlated. If there is a correlation in the work cycle data, an association is generated between the first and second machines and the association is applied to enable inheritance of material type between the first and second machines to support automated mass haul monitoring, and generate and implement a construction plan.
