Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing equipment registration systems do not account for positioning errors when registering the position of equipment, leading to potential misplacement during maintenance, as the error in position information is not considered, which can result in equipment being difficult to find.

Innovation Solution

The equipment registration terminal determines its own position using various positioning means and estimates the positioning error, registering the equipment's position along with the error, providing accurate installation coordinates and search ranges for maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If position information is registered without considering positioning error, then the registration process is simple, but the position accuracy during maintenance deteriorates

Engineering Contradiction:
Improveregistration process complexityVSAvoidposition accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system performs preliminary error estimation during the equipment registration phase by calculating positioning errors based on the relationship between the terminal device and equipment position. This advance preparation stores error information in advance, so that when maintenance occurs, the pre-calculated error data is already available to guide workers to the correct equipment location, eliminating the need for complex real-time error calculations during maintenance operations.

Solution Approach 1:

The system utilizes the terminal device's own positioning capabilities and the spatial relationship between the terminal and equipment to automatically calculate positioning errors. The terminal device itself provides the reference frame for error estimation, eliminating the need for external complex measurement systems. The error calculation is performed automatically based on pre-stored position information and current terminal position, making the process self-contained and reducing overall system complexity.
