Construction Machine Remote Control Event Reporting for Timely Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for construction machines face inefficiencies due to operators struggling to accurately recognize the timing for starting control of multiple machines, leading to delays or unnecessary waiting, which reduces operation efficiency.
Innovation Solution
A remote control system that includes a server to detect predefined events associated with each construction machine and reports these events to the operator through reporting devices, allowing for timely recognition and initiation of control, with optional automatic engine activation based on event urgency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the timing for starting control of each construction machine is set to a predetermined time point in advance, then the operator can recognize the timing clearly, but the actual work cannot start immediately when conditions are ready, causing waiting time and reduced efficiency
Solution Approach 1:
The system performs preliminary detection of events (truck arrival, loading completion, etc.) that indicate when machine control should start. By detecting these precursor events in real-time, the system enables the operator to start control at the optimal moment rather than waiting for predetermined times or reacting too late.
Solution Approach 2:
The system provides feedback to the operator through the reporting device when specific events occur at construction sites. This real-time feedback mechanism allows the operator to recognize the exact timing when control should be started, balancing timely response with accurate timing recognition.
2Adaptability or versatility
If the operator manually monitors and switches between multiple construction machines, then control flexibility is maintained, but operation efficiency decreases due to delayed or mistimed switching operations
Solution Approach 1:
The system introduces an intermediary event detection mechanism between the construction machines and the operator. The reporting device acts as a mediator that processes information from multiple machines and presents it to the operator in a standardized format, enabling efficient monitoring and switching while maintaining control flexibility.
3Productivity
If the operator switches control between multiple construction machines frequently, then work site progress can be optimized, but the complexity of managing multiple machines increases
Solution Approach 1:
The system segments the information from multiple construction machines into distinct, machine-specific event reports. This segmentation allows the operator to process information from each machine independently through the reporting device, making it easier to manage multiple machines without being overwhelmed by consolidated complex information.

AI summary
A remote control system 1 comprises a server 50 configured to acquire, for each of a plurality of construction machines 10, information indicating whether a predetermined event related to a machine control request timing which is a timing at which control of each of the plurality of construction machines 10 is to be started has occurred, and reporting devices 44, 45 configured to output report information to an operator according to an instruction from the server 50. With respect to any one of the plurality of construction machines 10, the server 50 is configured to, when acquiring information indicating occurrence of the predetermined event associated with the construction machine, output report information indicating the occurrence from the reporting devices 44, 45.
