Abstract

The invention of the present application intends to provide a completed-work information processing system that can generate terrain profile data that is easy to associate with the contents of work and a work area, on the basis of working history data that can be acquired in work execution by a work machine. For this purpose, a computation device computes movement loci of a work device when the work device is executing work of the ground and acquires working information from a working information acquiring device when determining that the work device is executing the work of the ground, records data in which the working information is associated with the movement loci of the work device, as the working history data, and outputs the terrain profile data to which the working information is added, with use of a movement locus assumed to be the current terrain profile among the movement loci of the work device included in the working history data and the working information associated with the movement locus assumed to be the current terrain profile.

First claim

The invention claimed is:

1 . A completed-work information processing system including a computation device that generates terrain profile data that represents a current terrain profile obtained after work execution by a work device of a work machine, the completed-work information processing system comprising:
an operation amount sensor that senses an operation amount of the work machine; position-posture sensors that sense a position of the work machine and a posture of the work device; a driving state sensor that senses a driving state of the work device; and a display device capable of displaying information outputted from the computation device, wherein the computation device is configured to:
determine whether or not the work device is executing work of the ground, on a basis of sensed values from the operation amount sensor, the position-posture sensors, and the driving state sensor,
compute coordinate information of multiple points on a plane that configures the movement loci of the work device when the work device is executing the work of the ground and acquire working date-and-time information when the work device is executing the work of the ground from an internal clock of the computation device in a case of determining that the work device is executing the work of the ground,
record data in which the working date-and-time information are associated with the coordinate information of the multiple points on the plane that configures the movement loci of the work device, as working history data,
extract from the working history data coordinate information of the multiple points assumed to be the current terrain profile and the working date-and-time information associated with the coordinate information of the multiple points assumed to be the current terrain profile based on the working date-and-time information or information regarding the height of the coordinate information of the multiple points on the plane that configures the movement locus of the work device among the working history data,
decide color information corresponding to the working date-and-time information extracted from the working history data according to a color palette in which a range of the working date-and-time information and different color information for each range are set, and
generate the terrain profile data to which the color information is added, with use of the coordinate information of the multiple points assumed to be the current terrain profile among the coordinate information of the multiple points on the plane that configures the movement loci of the work device included in the working history data and the color information of the working date-and-time information associated with the coordinate information of the multiple points assumed to be the current terrain profile, and
output the terrain profile data to which the color information is added to the display device, and
wherein the display device is configured to render the shape and color of the terrain profile based on the terrain profile data to which the color information is added and present them to the user.
