Disaster Countermeasure Server for Work Machine Risk Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work machines are at risk of failure due to external or internal water flooding, necessitating a real-time system to assess and communicate the likelihood of disaster impact.
Innovation Solution
A disaster countermeasure support server that recognizes rainfall levels and predicts the risk of work machine impact, generating a hazard map to alert operators and facilitate preventive measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time disaster risk prediction is implemented for work machines, then the reliability of work machine operation is improved, but the device complexity increases due to rainfall recognition and hazard map generation systems
Solution Approach 1:
A disaster countermeasure support server acts as an intermediary between rainfall data sources and work machine operators. The server receives rainfall information, performs hazard assessments, generates hazard maps, and transmits results to terminal devices, thereby reducing the complexity burden on individual work machines while maintaining reliable disaster risk prediction capabilities
Solution Approach 2:
The disaster countermeasure support server provides universal service to multiple work machines simultaneously. By centralizing the rainfall recognition and hazard map generation functions, a single server can support numerous work machines across different locations, reducing overall system complexity compared to equipping each machine with independent prediction capabilities
2Loss of time
If hazard maps are generated and transmitted to operators in real time, then the loss of time for disaster response is reduced, but the loss of energy increases due to continuous data processing and communication
Solution Approach 1:
The system implements periodic hazard assessment and map generation based on rainfall data thresholds and time intervals. The disaster countermeasure support server continuously monitors rainfall information and generates hazard maps at appropriate intervals or when significant changes occur, rather than maintaining constant high-energy processing, thereby reducing overall energy consumption while maintaining timely disaster response capability
Solution Approach 2:
The system performs preliminary hazard assessments by analyzing rainfall data and generating hazard maps before actual disasters occur. By proactively identifying high-risk areas and transmitting warnings to operators in advance, the system enables preventive actions without requiring continuous high-energy real-time processing during normal conditions

AI summary
The possibility of a work machine 40 being affected by a disaster in a second designated area including an existence position of the work machine 40 is predicted based on an amount of rainfall in a first designated area. A hazard map representing a result of the prediction of the possibility of the work machine 40 being affected by a disaster in the second designated area is outputted to a remote output interface 220 in a remote operation apparatus 20 (a client) (or a management output interface 620 in a management client 60). Accordingly, a user can take measures to reduce the possibility of the work machine being affected by a disaster, for example, to communicate with the persons involved in order to move the work machine 40 from a current position.
