Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for generating terrain profile data from working history data fail to associate the data with work area and content information, making it difficult to understand the relation between the terrain profile and the work executed by a work machine.
Innovation Solution
A completed-work information processing system that includes operation amount sensors, position-posture sensors, and driving state sensors to determine work execution, compute movement loci, and associate working information with terrain profiles, generating terrain profile data that is easier to relate to work area and content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If terrain profile data is generated from working history data using conventional methods, then terrain profile data can be obtained without special measuring equipment, but the terrain profile data cannot be easily associated with work area and contents of work
Solution Approach 1:
The patent combines terrain profile data with working history data including work area information and contents of work information into a single integrated data structure. This merging allows the terrain profile to be automatically associated with specific work areas and work contents without requiring separate measurement equipment or manual association processes.
Solution Approach 2:
The working history data collection system is enhanced to serve multiple functions: it not only records terrain profile information but also captures work area data and work contents information. This multi-functionality allows a single data collection mechanism to provide comprehensive information needed for both terrain mapping and work management.
2Device complexity
If only three-dimensional position information is recorded in terrain profile data, then data structure remains simple, but it becomes difficult to associate terrain profile with work area and contents of work
Solution Approach 1:
The patent segments working history data into distinct information categories including three-dimensional position information, work area information, and contents of work information. This segmentation allows the system to maintain organized, structured data while capturing comprehensive work context, making it easier to process and associate different types of information.
3Productivity
If terrain profile data is generated without working information, then data processing is simpler, but progress management and work area association become difficult
Solution Approach 1:
The patent implements preliminary action by collecting and organizing working information including work area and contents of work information during the work execution process itself. This preliminary collection ensures that when terrain profile data is generated, the associated work context information is already available and properly structured, eliminating the need for separate data collection or association steps.

AI summary
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.
