Worksite Operation History Mapping for Multi-Machine Collision Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately reproduce the situation of a worksite with multiple work machines, leading to inadequate grasp of accident occurrence risks, including contact risks.
Innovation Solution
An operation history management system that includes a server to manage and process operation history data, integrating work machine trajectories, terrain, and object information to visualize potential accident risks on a map, displayed on a terminal device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operating information of a single work machine is collected, then detailed operating information can be confirmed remotely, but the situation of the worksite where multiple work machines operate cannot be accurately reproduced
Solution Approach 1:
The patent merges operating information from multiple work machines into a unified database, associating each machine's data with position information and terrain data to create a comprehensive worksite representation that accurately reproduces the situation where multiple machines operate together
Solution Approach 2:
The patent adds spatial dimension by incorporating position information and map data with terrain features into the operating information system, transforming single-machine operational data into multi-dimensional worksite context that enables accurate situation reproduction and accident risk analysis
2Productivity
If multiple work machines operate in the same worksite, then productivity increases, but accident occurrence risks such as contact risks between machines increase
Solution Approach 1:
The patent implements feedback by analyzing the reproduced worksite situation and operation histories to identify accident risks, then providing this information back to operators and managers to enable corrective actions and improve safety in future operations
Solution Approach 2:
The patent performs preliminary action by reproducing and analyzing operation histories to identify potential accident risks before they occur, allowing preventive measures to be taken in advance to avoid contact risks between multiple work machines

AI summary
To allow a user to accurately grasp an accident occurrence risk including a contact risk in a worksite where a plurality of work machines operate and to encourage implementation of safety measures. An operation history management system 100 includes a server 31 that manages operation history of a work machine 33 and a terminal device 34. The server 31 includes an information storage device 312 that stores operating information of the work machine 33 in association with a time of acquisition of the operating information and position information of the work machine 33 at the time, and stores a map 60 including information of a terrain 61 and an object 62 in a worksite 32, and an information processing device 311 that draws a movement trajectory of the work machine 33 operating in the worksite 32 and another work machine 33 operating in the worksite 32 on the map 60 having drawn thereon the terrain 61 and the object 62 in the worksite 32, and causes the terminal device 34 to display.
