Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional system for performing work and traveling on work ground with a large area using predetermined traveling-system operations and work-system operations is used, then the system is simple to implement, but it cannot realize non-simple work traveling with frequent traveling-system operations and work-system operations in confined agricultural fields
Solution Approach 1:
The slave work vehicle copies the master work vehicle's operations by detecting its position and generating corresponding work/driving parameters. The system records the master vehicle's traveling track and emulates its operations (deceleration, acceleration, stopping, starting, and work implement operations) in the slave vehicle, enabling complex work traveling without requiring complex predetermined operation sequences
Solution Approach 2:
The system performs preliminary detection and recording of the master work vehicle's position and operations before the slave vehicle executes its emulated operations. By detecting the master vehicle's position in advance and generating corresponding work/driving parameters linked with target traveling positions, the slave vehicle can appropriately perform complex traveling operations in confined fields
2Measurement precision
If the slave work vehicle is controlled to follow the master work vehicle using predetermined traveling-system operations and work-system operations, then the control system is simple, but it is difficult to accurately emulate operations such as deceleration, acceleration, stopping, and starting in complex routes
Solution Approach 1:
The system continuously detects the master work vehicle's position using GPS and other detection modules, and uses this feedback information to generate corresponding work/driving parameters for the slave vehicle. By linking operations with detected positions and target traveling positions, the system accurately emulates the master vehicle's deceleration, acceleration, stopping, and starting operations in complex routes
Solution Approach 2:
The system changes the parameters of work/driving operations based on the detected position of the master vehicle. By generating work/driving parameters that are linked with target traveling positions rather than using fixed predetermined operations, the slave vehicle can dynamically adjust its operations to accurately follow the master vehicle's movements in confined fields with complex routes
3Productivity
If the slave work vehicle emulates the master work vehicle's operations in confined fields with frequent traveling-system and work-system operations, then the work efficiency is improved, but the requirement for precise navigation and parameter matching increases
Solution Approach 1:
The system segments the emulation process into distinct functional modules: position detection module, traveling track calculation unit, parameter generation unit, and navigation control unit. Each module handles specific aspects of the emulation, making the complex task of matching parameters manageable and precise while maintaining high work efficiency in confined fields
Solution Approach 2:
The navigation control unit performs multiple functions including position detection, track calculation, parameter generation, and operation control. This multi-functional approach allows the system to maintain precise parameter matching while improving work efficiency, as the same control unit handles all aspects of the slave vehicle's emulated operations
