Automated Traverse Line Projection for GPR Scanning Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing scanning systems, such as GPRs, require significant time for operators to mark traverse lines, which prolongs the process of scanning buried objects like pipelines, making the scanning process inefficient.
Innovation Solution
A scanning system and method that includes a scanning guide generation device with an input unit for receiving pipeline information and setting information, a traverse line determination unit to determine the traverse line, and a device control unit to display or project a guide line, allowing the scanning device to move along the determined path efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an operator manually marks a traverse line using traditional methods (choke, leveling string), then the traverse line can be accurately established for scanning, but the time required for marking exceeds the time required for the scanning itself
Solution Approach 1:
The patent replaces the manual mechanical method of marking traverse lines with chalk or string with an automated optical projection system. The projection device projects the traverse line directly onto the ground surface, eliminating the need for manual marking operations while maintaining accuracy through automated calculation and projection.
Solution Approach 2:
The system enables self-service by automatically determining and projecting the traverse line without requiring operator intervention for marking. The scanning device or guide device autonomously calculates the optimal traverse line based on the target object's position and projects it, allowing the operator to simply follow the projected line.
2Reliability
If the scanning system waits for manual traverse line marking before scanning, then the scanning can be performed along the correct path, but the overall scanning process time is significantly prolonged
Solution Approach 1:
The system performs preliminary action by pre-calculating and projecting the traverse line before the scanning operation begins. This allows the operator to immediately start scanning along the projected line without delay, as the path has already been determined and marked on the ground.
Solution Approach 2:
The automated projection system replaces the time-consuming manual marking process, enabling rapid establishment of the scan path. This substitution maintains path accuracy through automated calculation while dramatically reducing the time required to prepare for scanning.
3Ease of operation
If traditional manual methods are used to establish traverse lines, then the scanning can be performed, but the operator workload and time investment for preparation exceed the actual scanning time
Solution Approach 1:
The patent replaces manual marking operations with an automated projection system that calculates and projects the traverse line electronically. This substitution maintains ease of operation by providing clear visual guidance on the ground while eliminating the physically demanding and time-consuming manual marking process.
Solution Approach 2:
The system performs self-service by automatically determining the optimal traverse line path and projecting it without operator intervention. The operator simply needs to input basic parameters, and the system handles the complex calculations and projection, significantly reducing preparation time and workload.
