Operation Recognition Device for Power Panel Error Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During maintenance and inspection operations of power control panels, operators may incorrectly interpret procedures due to unfamiliarity with the devices, leading to potential errors, and existing monitoring systems can only recognize errors after the operation is performed, lacking real-time prevention.
Innovation Solution
An operation recognition device that acquires movement and area information using sensors and cameras to estimate the user's operation position and determine if it aligns with the correct operation section, providing warnings before errors occur by calculating contact likelihood and using probability density distributions for accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monitoring systems are used to recognize operation errors, then error detection capability is improved, but error recognition can only occur after the operation is performed
Solution Approach 1:
The system performs preliminary recognition of the user's intended operation position using movement information and probability density distributions before the actual contact occurs. This allows the system to predict and warn about potential errors in advance, rather than detecting them only after the operation is completed.
Solution Approach 2:
The system provides real-time feedback to the user by displaying the estimated operation position and issuing warnings when the estimated position does not match the correct operation section. This continuous feedback loop enables users to correct their actions before errors occur.
2Adaptability or versatility
If multiple buttons and switches are provided on inspection target devices, then device functionality is improved, but operation accuracy deteriorates due to operator unfamiliarity
Solution Approach 1:
The system replaces manual verification of operator familiarity with automated recognition technology. Instead of relying on operators to correctly identify and operate multiple buttons and switches based on their knowledge, the system uses sensors and probability density distributions to automatically recognize the user's intended operation position and provide guidance.
3Ease of operation
If procedure manuals are used to guide operations, then operation guidance is improved, but misinterpretation errors increase due to operator unfamiliarity
Solution Approach 1:
The system introduces an intermediary layer between the operator and the device by providing real-time visual feedback about the estimated operation position. This intermediary system translates the complex interaction between operator intent and device state into simple, actionable guidance that reduces misinterpretation of procedure manuals.

AI summary
According to one embodiment, there is provided an operation recognition device comprising a computer including a hardware processor. The hardware processor is configured to acquire movement information associated with a movement of a user, and area information corresponding to a first operation section; determine, based at least in part on the movement information and the area information corresponding to the first operation section, an estimated position corresponding to a subsequent operation by the user; and determine whether the subsequent operation by the user is directed to the first operation section based at least in part on the estimated position corresponding to the subsequent operation.
