Remote Work Machine Warm-Up Scheduling for On-Time Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of remotely operated work machines do not easily recognize the need for a warm-up operation due to their distance from the machine, leading to delayed work initiation in low-temperature environments.
Innovation Solution
An operation support server estimates the internal state of the work machine using external variables and predicts a warm-up operation based on scheduled use, ensuring the machine is ready at the designated time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator remotely operates the work machine without warm-up operation support, then the operator can work from a distance, but the operator does not recognize the need for warm-up operation in low-temperature environments
Solution Approach 1:
The operation support server receives operation schedules from the remote operation apparatus and automatically determines warm-up operation timing based on the scheduled operation time and environmental temperature data. This feedback mechanism compensates for the operator's lack of awareness by providing automated warm-up control despite the remote operation setup.
Solution Approach 2:
The system enables self-service warm-up operation control where the operation support server autonomously determines and executes warm-up operations based on pre-stored operation schedules and temperature data, without requiring continuous operator intervention or awareness of the warm-up need.
2Productivity
If the operator starts work immediately at the designated time, then time efficiency is improved, but the machine's internal state may not satisfy the designated condition
Solution Approach 1:
The operation support server determines the warm-up operation start time based on the scheduled operation time and predicts the machine's internal state during the warm-up period. This preliminary action ensures the machine reaches the required internal state (e.g., temperature conditions) before the designated work start time, guaranteeing both timely operation and machine readiness.
3Measurement precision
If the system performs warm-up operation based on real-time temperature monitoring only, then the machine state accuracy is improved, but the warm-up operation cannot be completed by the designated time
Solution Approach 1:
The operation support server stores operation schedules in advance and uses these pre-stored schedules to determine warm-up operation timing. By combining real-time temperature monitoring with predetermined operation schedules, the system calculates the optimal warm-up start time that ensures both accurate temperature control and timely completion before the scheduled operation time.

AI summary
There is provided a technique capable of appropriately controlling a warm-up completion timing of a work machine in view of scheduled use of the work machine. A warm-up period elapsed until a measurement value of an internal state variable satisfies a designated condition, i.e., warm-up is completed since a warm-up operation of a work machine 40 was started is predicted based on a measurement value of an external state variable with an operation of the work machine 40 stopped. The warm-up operation of the work machine 40 is started at a first designated time t1 as an appropriate timing based on the predicted warm-up period such that the measurement value of the internal state variable of the work machine 40 satisfies the designated condition by a second designated time t2.
