Work Machine Operation Assistance for Consistent Performance Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently obtaining consistent performance information for work machines, particularly in construction sites where different machines may have varying performance data, leading to inefficiencies in work planning.
Innovation Solution
An operation assistance module and an image generation application that cooperate with an operation control unit to request and acquire performance information from a performance information server, using model information and attitude conditions to ensure accurate and consistent data reflection in work machine control and image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual reference to rated total load tables is used to obtain performance information, then performance information can be obtained, but work efficiency is poor and the process is cumbersome
Solution Approach 1:
The work machine automatically obtains performance information through its own performance information acquisition unit without requiring manual intervention. The machine queries the performance information server using its model information and current working conditions, and automatically receives and processes the performance data, eliminating the need for operators to manually consult rated total load tables.
Solution Approach 2:
The manual mechanical process of consulting printed or displayed rated total load tables is replaced by an automated electronic information system. The performance information acquisition unit electronically queries the server and receives performance data, substituting the manual lookup process with an automated digital information retrieval system.
2Reliability
If arithmetic expressions are updated for each work machine by maintenance workers, then performance information can be calculated, but there is a possibility that not all work machines are updated with the latest arithmetic expression
Solution Approach 1:
The arithmetic expressions and performance information calculation capabilities are merged into a centralized performance information server. All work machines of the same type query this single server, ensuring that everyone receives the same latest version of arithmetic expressions and performance data without requiring individual updates at each machine.
Solution Approach 2:
The performance information server acts as an intermediary between the arithmetic expression updates and the work machines. Instead of directly updating each machine, the server receives and processes updates, then provides the latest arithmetic expressions to all querying machines, ensuring consistency across the fleet.
3Adaptability or versatility
If different arithmetic expressions are used in work machines of the same type, then each machine can calculate performance information, but the performance information obtained may be different between machines
Solution Approach 1:
The performance information server provides universal service to all work machines of the same type. It maintains a single set of arithmetic expressions and performance data that is shared with all machines, ensuring that every machine receives identical performance information for the same working conditions, thereby guaranteeing consistency across the entire fleet.

AI summary
An operation assistance module operates in coordination with an operation control unit that controls the actions of a work machine, or with an operation control unit of an image generation application that controls the actions of an image of the work machine displayed on a display unit, wherein the operation assistance module has: a request issuance unit that transmits, to a performance information server, a request including machine type information for a work machine and a performance information request to indicate performance information for the work machine; a response acquisition unit that receives from the performance information server a response including the requested performance information; and an operation assistance unit that reflects the acquired performance information in the control of the operation control unit.
