Construction Management System for Vehicle Arrival Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work machines at construction sites cannot determine the timing of transport vehicle arrivals at loading or unloading sites, making it difficult to prepare for earth and sand loading or unloading.
Innovation Solution
A construction management system that includes position information acquisition, notification area specification, and output units to notify work machines when a transport vehicle enters a predetermined area, using communication terminals to provide timely notifications and manage site changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If position information is acquired and notification areas are specified to enable timely alerts, then productivity is improved through better coordination, but device complexity increases due to additional communication and positioning systems
Solution Approach 1:
A server acts as an intermediary between transport vehicles and work machines. The server receives position information from vehicles, determines notification areas, and sends alerts to work machines, thereby coordinating operations without requiring direct complex communication between all devices
Solution Approach 2:
The server performs multiple functions including position information acquisition, notification area determination, and alert generation within a single system, reducing the need for separate specialized devices for each function
2Loss of time
If real-time position monitoring is implemented to detect vehicle arrivals, then loss of time is reduced through timely preparation, but use of energy increases due to continuous communication and positioning operations
Solution Approach 1:
Position information is acquired and notifications are sent at periodic intervals rather than continuously. The system checks vehicle positions at defined intervals and sends alerts when vehicles enter notification areas, reducing communication energy consumption while maintaining timely coordination

AI summary
A construction management system includes a position determination unit that determines whether or not a transport vehicle associated with a construction site is located within a notification area associated with the construction site, and an output unit that outputs an indication that the transport vehicle is located within the notification area to a communication terminal associated with the construction site when the position determination unit determines that the transport vehicle is located within the notification area.
