Map Scale Adjustment for Multi-Device Position Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position information display methods for multiple agricultural work devices require users to manually adjust map scales and ranges to effectively show all device positions, which can be cumbersome and inefficient, especially when devices are distributed over a wide area.
Innovation Solution
A position information display method and system that acquires and processes position data from multiple work devices, generates range information, and calculates an optimal scale for displaying this information on a map, allowing for automatic adjustment and efficient visualization of device positions without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of map scale and range is used to display all work device positions, then complete visibility of all devices is achieved, but user operation complexity and time consumption increase
Solution Approach 1:
The system automatically calculates the optimal map display range and scale based on the positions of multiple work devices, eliminating the need for users to manually adjust the map. The calculation unit computes the minimum bounding rectangle encompassing all device positions and determines the appropriate scale factor, allowing the system to self-adjust the display parameters without user intervention.
2Productivity
If automatic scale calculation is implemented to reduce manual adjustment, then operation efficiency improves, but system complexity increases
Solution Approach 1:
The system performs preliminary calculations to determine the optimal map display parameters before the user actually needs to view the device positions. By proactively computing the bounding rectangle and scale factor based on current device positions, the system prepares the optimal display configuration in advance, eliminating the need for manual adjustment when the user views the map.
3Adaptability or versatility
If fixed map scale is used for display, then system simplicity is maintained, but adaptability to different device distributions deteriorates
Solution Approach 1:
The system dynamically adjusts the map display scale and range based on the actual spatial distribution of work devices. Instead of using a fixed scale, the calculation unit continuously determines the optimal scale factor by computing the bounding rectangle of device positions and adjusting the map parameters to fit the display area, allowing the system to adapt to various device distributions automatically.

AI summary
A position information display method includes acquiring position information indicating positions of a plurality of work devices, generating range information indicating a first range in which the positions are distributed on a predetermined map, calculating a scale for outputting display information including the first range, in map information representing the map, to a predetermined display region of a display device, and outputting the display information indicating the distribution of the positions in the first range based on the position information, the range information, and the scale.
