A remote control system 1 comprises a server 50 configured to acquire, for each of a plurality of construction machines 10, information indicating whether a predetermined event related to a machine control request timing which is a timing at which control of each of the plurality of construction machines 10 is to be started has occurred, and reporting devices 44, 45 configured to output report information to an operator according to an instruction from the server 50. With respect to any one of the plurality of construction machines 10, the server 50 is configured to, when acquiring information indicating occurrence of the predetermined event associated with the construction machine, output report information indicating the occurrence from the reporting devices 44, 45.

In order to monitor operation situations of site resources at a construction site efficiently, a measuring system uses a surveying apparatus 100 including a camera and a position-determining function using laser light, and the measuring system includes a photographing means for continuously photographing construction machines 201 to 204 which are site resources for performing operations at a construction site by the camera, a recognizing means recognizing the site resources in photographed images obtained by the photographing, a tracking means for tracking the image of the site resources recognized in the multiple photographed images obtained by the continuous photographing, and a position-determining means collimating to the site resources which are objects for the tracking, and determining the positions of site resources by the position-determining function, in which the determining of positions is performed multiple times at intervals.

A surveying device is operated to measure a surface profile of a terrain of a worksite and generate surface profile data indicative of the surface profile. A work machine is operated to move along a route over the terrain in accordance with an operating parameter and generates machine operational data indicative of the operating parameter. A navigation system determines the route and generates route data. A processing unit processes the route data, machine operational data and surface profile data to generate monitored operating condition data indicative of a monitored operating condition of the machine.

Provided are a server and system which allow a plurality of people involved in work to share information about an object requiring attention in a work area. A work environment image, which indicates an extension mode of a target object in a real space in a target object image region R that is a part of a captured image obtained through an imaging device (e.g., an imaging device 612) of a first client (e.g., a worker terminal 60) and target object related information, is outputted to an output interface (e.g., a remote output interface 220) of a second client (e.g., a remote operation device 20).

A display device for a shovel that includes an attachment including a boom, an arm, and an end attachment includes an operation analysis start input part and an operation analysis check input part. The operation analysis start input part is configured to be operated to start an operation analysis of the shovel and store the history of the operation analysis. The operation analysis check input part is configured to be operated to display the result of the operation analysis.

A work machine including a sensing device, a user interface, and a control unit is disclosed. The control unit may be configured to generate a productivity layer based on productivity data, and generate an image layer based on image data. The image data may include information relating to an image corresponding to a state of an operation associated with a worksite and a geospatial reference associated with the image. The control unit may be configured to generate a composite image of the worksite based on a map layer, the image layer, and the productivity layer, and cause the composite image to be displayed via the user interface. The composite image may position the image layer relative to the map layer based on the geospatial reference and geographical coordinates corresponding to the geospatial reference, and position the productivity layer relative to the image layer.

A method for determining situational awareness in a worksite includes setting at least one environment modelling apparatus (EM) at least one of: on a machine or external from the machine; setting at least one tracking apparatus (TA) at least one of: on the machine or external from the machine; acquiring data by the at least one tracking apparatus (TA); and acquiring data by the at least one environment modelling apparatus. Further, the method includes receiving, by at least one position determination unit (PDU), data related to the at least one tracking apparatus (TA) and data related to the at least one environment modelling apparatus (EM); and determining, by the at least one position determination unit (PDU), based at least in part on the received data, the location and orientation of the machine in the worksite.

The transport vehicle position estimating device includes: a distance image acquiring part for acquiring a distance image of a box bed; and a calculation part. The calculation part sets a box bed scope indicative of a positional extent of the box bed on the basis of the distance image of the box bed acquired by the distance image acquiring part. The calculation part acquires a dischargeable region indicative of a dischargeable extent of the attachment under the condition that the attachment is operated but the lower travelling body is not travelled. The calculation part determines whether the box bed scope falls within the dischargeable region.

The wheel loader (10) includes a vehicle main body (1), a rear detection section (71), a vehicle main body angle sensor (72), and a controller (26). The rear detection section (71) detects an obstacle (5) in the rear of the vehicle main body (1). The vehicle main body angle sensor (72) detects the inclination state of the vehicle main body (1). The controller (26) determines the control corresponding to the detection by the rear detection section (71), based on the inclination state of the vehicle main body (1) detected by the vehicle body angle sensor (72).

Provided are a server and a system which enable a worker of a work machine to intuitively recognize work contents and the like to be performed using the work machine in each of a plurality of work locations. In response to a first designated operation through a remote input interface 210 of a remote operation device 20, a remote output interface 220 of the remote operation device 20 outputs a work environment image showing positions of designated work locations Q1 and Q2, and information about at least one of a designated work period and a designated work content. The designated work location, the designated work period and the designated work content are included in designated work information that is work information fitting a designated position depending on the first designated operation among a plurality of pieces of work information registered in a database 102.
