Work Machine Data Priority Control Under Fleet Network Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to appropriately transmit operation data from multiple machines when the number is large, leading to potential loss or delayed transmission of critical information, especially for high-priority machines.
Innovation Solution
A work machine and management system that determine transmission priority based on failure probability, importance level, and replaceability, using a controller to prioritize and manage data transmission.

Engineering Contradiction Analysis
1Quantity of substance
If the number of work machines is large, then the total amount of operation information data increases, but the network traffic capacity becomes insufficient to transmit all data
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different work machines based on their individual characteristics (failure probability, importance level, replaceability). This allows the system to differentiate transmission requirements for each machine rather than treating all machines uniformly, enabling efficient use of limited network capacity by prioritizing critical data from high-risk machines.
Solution Approach 2:
The patent changes the parameter of data transmission by introducing priority-based transmission timing. Instead of transmitting all operation information simultaneously or at fixed intervals, the system adjusts transmission parameters (timing, frequency) based on the calculated priority level of each machine, thereby optimizing network traffic utilization.
2Loss of energy
If data transmission is delayed or discarded due to capacity limits, then network traffic capacity is preserved, but critical information from high-priority machines may be lost
Solution Approach 1:
The patent applies preliminary action by calculating and determining the priority level of each work machine in advance, before actual data transmission occurs. This pre-assessment allows the system to prepare transmission schedules and allocate network resources proactively, ensuring that critical information from high-priority machines is transmitted first and not lost during capacity constraints.
Solution Approach 2:
The system uses feedback by continuously monitoring operation information and adjusting transmission priorities based on current machine status. The priority determination is not static but dynamically updated based on changing conditions, ensuring that critical information is always identified and transmitted appropriately.
3Loss of information
If all operation information is transmitted simultaneously, then complete information is available, but transmission time and network congestion increase
Solution Approach 1:
The patent applies segmentation by dividing the transmission of operation information into priority-based segments. Instead of transmitting all data simultaneously, the system segments transmission into multiple batches according to priority levels, with high-priority machines transmitted first. This reduces overall transmission time and prevents network congestion while ensuring complete information is eventually received.

AI summary
Provided is a work machine and a work machine management system that enable more appropriate transmission of information of a high-priority work machine even when there is a large number of work machines. A work machine 10 comprises an information controller 20. The information controller 20 acquires operation information of the work machine 10; receives management server information from a management server 90 provided outside the work machine 10; determines a transmission priority order of the operation information based on content of the operation information and the management server information; and transmits the operation information to the management server 90 or a relay 80 according to the transmission priority order.
