Construction Machine IMU Identification Through Sequential Member Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying posture information detection sensors on multiple front members of construction machines, such as hydraulic excavators, are labor-intensive and prone to errors, especially when simultaneous operations complicate the identification process.
Innovation Solution
An automatic sensor identification system that sequentially drives and stops front members individually, using a control unit to identify posture information detection sensors based on detection value changes, reducing operator intervention and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If posture information detection sensors are used with common specifications mountable on various front members, then standardization is achieved, but it takes time and labor to sequentially mount and identify the sensors on each front member
Solution Approach 1:
The sensor identification system performs automatic identification by itself without requiring operator intervention for sequential mounting and identification. The control unit automatically detects which sensor is mounted on which front member by analyzing detection signals, thereby resolving the contradiction between standardization and identification time.
2Ease of operation
If posture information detection sensors with dedicated identification information are used for each front member, then identification is simplified, but the sensors cannot be standardized and it takes labor and cost to manage parts
Solution Approach 1:
The control unit serves multiple functions: it not only controls the working machine but also automatically identifies which sensor is mounted on which front member by analyzing detection signals. This universal approach allows standard sensors to be used across different front members while maintaining easy identification capability.
3Productivity
If identification task is performed while common tasks such as digging are operating, then time is saved, but it may take time to complete identification because multiple front members are often driven at the same time
Solution Approach 1:
The system segments the identification process by analyzing detection signals from individual front members separately, even when multiple front members are driven simultaneously. The control unit can distinguish and identify sensors on each front member independently by processing their respective detection signals, thereby maintaining identification accuracy while improving productivity.

AI summary
PROBLEM TO BE SOLVED: To reduce the burden of an operator when performing a task for identifying which posture information detection sensor is mounted on which front member in a construction machine where the posture information detection sensors (IMU) are mounted on multiple front members constituting a working machine. SOLUTION: An automatic identification system is provided which has an identification task start button (13b) for being operated to start an identification task, a front member control means (25a) for outputting a control instruction for driving and stopping multiple front members (stick 6, boom 5) sequentially, individually, and automatically, and a sensor identification means (25b) for identifying IMU (22) mounted on each front member based on changes of a detection value of IMU (22) as said each front member is driven by the front member control means (25a).
