Work Machine Camera Bandwidth Control by Operation Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In work machines equipped with multiple cameras, the limited bandwidth allocated for remote control operations often results in unnecessary waste, as all cameras are allocated equal bandwidth, leading to degraded video quality when only a subset is actively used.
Innovation Solution
A controller monitors the operations of a work machine's implements, determines the specific operation being performed, and adjusts the bandwidth of associated cameras by increasing the bandwidth for active cameras and decreasing it for inactive ones, based on camera view information stored in a data structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If equal bandwidth is allocated to each camera, then bandwidth distribution is simple and fair, but video stream quality degrades when not all cameras are utilized
Solution Approach 1:
The system dynamically adjusts bandwidth allocation based on real-time operational status. The controller monitors which cameras are currently needed for the machine's operation and allocates bandwidth accordingly, transitioning from static equal allocation to dynamic adaptive allocation that responds to changing operational requirements
Solution Approach 2:
The system changes the bandwidth parameter for individual cameras based on operational context. When a camera is determined to be actively used during a specific operation, its bandwidth parameter is increased; when not needed, bandwidth is reduced or reallocated to other cameras, optimizing overall system performance
2Productivity
If limited bandwidth is allocated to cameras, then wireless transmission is feasible, but video stream quality is degraded
Solution Approach 1:
Instead of uniform bandwidth allocation, the system applies local quality optimization by allocating different bandwidth levels to different cameras based on their specific operational relevance. Each camera receives bandwidth proportional to its current importance, ensuring high-quality video streams for critical views while maintaining transmission feasibility
3Adaptability or versatility
If bandwidth is allocated to all cameras, then all views are available, but bandwidth is wasted when some cameras are not utilized
Solution Approach 1:
The system extracts and isolates the bandwidth consumption of individual cameras, allowing selective allocation. By separating bandwidth allocation from fixed universal allocation, the system can remove bandwidth from unused cameras and redirect it to actively used cameras, eliminating waste while maintaining necessary view availability
Solution Approach 2:
The controller implements a feedback mechanism that continuously monitors camera usage based on machine operations. This feedback loop enables real-time bandwidth reallocation, where information about which cameras are currently needed feeds back into the bandwidth allocation decision, preventing waste while ensuring adequate bandwidth for active cameras

AI summary
A controller may monitor a plurality of operations performed using one or more implements of the work machine. The controller may determine that the work machine is performing a particular operation based on monitoring the plurality of operations. The controller may obtain, based on information regarding the particular operation, camera view information, from a data structure, indicating that the particular operation is associated with a particular camera of a plurality of cameras of the work machine. Each camera, of the plurality of cameras, may capture a respective view of a plurality of views of the work machine. The controller may determine, based on the camera view information, that a bandwidth associated with a video stream, of a particular view of the work machine captured by the particular camera, is to be increased. The controller may increase the bandwidth associated with the video stream provided by the particular camera based on determining that the bandwidth is to be increased.
