Working Machine GNSS Communicator Layout for Stable Position Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machines face challenges in accurately and stably correcting measured positions due to unstable communication from correction information communicator assemblies, which can be disrupted by radio wave-blocking structures and excessive loads on communication harnesses, leading to potential communication failures.
Innovation Solution
The correction information communicator assembly is positioned in the vicinity of the operator's seat, preferably inside a mount with a radio wave-transparent cover, and is connected to a controller via a short communication cable, ensuring stable wireless communication and reducing exposure to vibrations and environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the correction information communicator assembly is mounted in locations with many low radio wave transparency elements (steel plates), then the assembly can be installed in various positions, but the communication becomes unstable and position correction accuracy deteriorates
Solution Approach 1:
A radio wave transparent cover is introduced as an intermediary component between the correction information communicator assembly and the surrounding steel plate structures. This cover mediates the radio wave transmission, allowing the assembly to be installed in various positions while maintaining stable communication by preventing radio wave blocking from adjacent metal structures.
2Ease of manufacture
If the correction information communicator assembly is mounted without determining the optimal location, then installation is simplified, but the assembly may contact surrounding structures due to vibrations or the communication harness may receive excessive load
Solution Approach 1:
The optimal mounting location is predetermined during the design phase, selecting a position on the vehicle body that is远离 from surrounding structures and vibration-prone areas. This preliminary determination ensures that the assembly is installed in the most suitable location before actual installation, preventing contact issues and harness overload while maintaining installation simplicity.
3Reliability
If the correction information communicator assembly is positioned away from radio wave blocking structures, then communication stability improves, but the assembly may be exposed to more vibrations and environmental factors
Solution Approach 1:
The radio wave transparent cover serves as a protective intermediary that shields the correction information communicator assembly from vibrations and environmental factors while maintaining radio wave transparency. This allows the assembly to be positioned optimally for communication stability without being directly exposed to harmful vibrations and environmental conditions.

AI summary
A working machine includes a vehicle body to travel, an operator's seat, a position detector to acquire position information from one or more positioning satellites, a correction information communicator assembly to wirelessly connect to an external communication network, and a controller configured or programmed to compensate for an error in the position information based on position correction information acquired from the external communication network. The correction information communicator assembly is located in a vicinity of the operator's seat.
