Trench Excavation Work Plans Using Orthographic Route Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current work planning systems for construction machinery lack standardization and precision, making it difficult to share work plans among workers and effectively utilize fully automatic excavators, especially when collaborating with unskilled workers or operating in complex work areas.
Innovation Solution
A work planning system that uses orthographic images and work data to set trench excavation work plans, including sequence points, work route lines, cross-sectional shapes, and construction tolerance ranges, which are then transmitted to worker terminals for precise execution, allowing for standardized and uniform work details and accurate sharing among stakeholders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If simple 3D design drawings are used for work plans, then the work plan can be provided quickly, but the work plan cannot be shared accurately among workers and collaboration problems arise
Solution Approach 1:
The patent creates a standardized digital work plan model that can be copied and shared across multiple worker terminals. This digital model includes structured data about work areas, sequence points, and machine positions, allowing accurate replication of the work plan information to all stakeholders without manual interpretation of drawings
Solution Approach 2:
The patent transforms the work plan from simple visual drawings into a parameterized digital model with specific coordinates, sequence numbers, and structured data fields. This parameterization enables precise information transmission and automated processing while maintaining quick preparation through standardized data structures
2Ease of operation
If operators determine work plans themselves from simple drawings, then flexibility is maintained, but standardization is lost and collaboration with unskilled workers becomes difficult
Solution Approach 1:
The system enables unskilled workers to access and understand work plans through standardized digital interfaces that present information in a consistent, easy-to-interpret format. The automated generation and distribution of work plans eliminates the need for operators to manually interpret drawings, allowing self-service execution of standardized plans
Solution Approach 2:
The standardized digital work plan model serves multiple functions: it can be viewed on different worker terminals, processed by automated excavation machines, and adapted to various skill levels. This universal format replaces multiple specialized drawing types with a single multi-functional digital standard
3Extent of automation
If fully automatic excavators are used, then automation is increased, but the work area can be expressed only for limited work
Solution Approach 1:
The patent implements dynamic work plans with sequence points and adjustable parameters that can be modified in real-time. The digital model allows the work area and sequence to be changed dynamically without requiring manual replanning, enabling automatic excavators to adapt to varying work requirements while maintaining high automation
Solution Approach 2:
The work area is divided into multiple sequence points with specific coordinates and parameters. This segmentation allows the automatic excavator to handle complex, multi-stage excavation tasks by processing each segment according to standardized digital instructions, thereby expanding the range of work areas that can be automated
Data Source
AI summary
In a method of making a work plan for construction machinery, construction site information including an orthographic image and work data are provided. A trench excavation work plan on the orthographic image is set based on the work data. The trench excavation work plan is configured to displays a work route line and a work position of construction machinery based on the work route line. The trench excavation work plan is transmitted to a worker terminal.
