Cockpit Around-View Warning for Construction Vehicle Risk Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction vehicles lack a comprehensive warning system that provides operators with complete information about surrounding risky objects, limiting their ability to effectively manage operational risks.
Innovation Solution
A cockpit warning and identification system that utilizes multiple cameras to capture surrounding images, processes them to create an around view image, performs image recognition to identify risky objects, and displays their status on a cockpit display, accompanied by visual and auditory alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional warning devices (reversing lights, rotating lights, buzzers) are used, then the warning function is provided, but the operator cannot obtain complete information about surrounding risky objects
Solution Approach 1:
The system divides the surrounding environment into multiple monitoring zones using several cameras positioned at different locations on the construction vehicle. Each camera captures images from its specific zone, and the processor divides the around-view image into corresponding areas for individual risk assessment and warning
Solution Approach 2:
The system combines images from multiple cameras into a single around-view image that provides a comprehensive view of the surrounding environment. The processor merges the captured images and performs unified image recognition to identify risky objects across all zones
2Reliability
If multiple cameras and image processing are added to provide complete surrounding information, then operator awareness is improved, but the device complexity increases
Solution Approach 1:
The processor performs multiple functions: it combines images from all cameras, performs image recognition to identify risky objects, determines risk levels, and controls multiple warning devices (display screens, LEDs, buzzers) based on the same risk assessment
Solution Approach 2:
The display device acts as an intermediary that presents processed risk information to the operator in an intuitive format. The system uses intermediate warning signals (different colored LEDs, warning patterns) to convey the status of risky objects before they become immediate threats

AI summary
A cockpit warning and identification system includes plural cameras, a processor, and a display device. The cameras are mounted on a construction vehicle and configured to capture surrounding images of the construction vehicle. The processor is disposed in the cockpit of the construction vehicle and is in signal connection with the cameras. The processor is configured to receive the surrounding images, combine the surrounding images into an around view image of the construction vehicle, and perform image recognition processing on the around view image to obtain a risk status of the construction vehicle. The display device is mounted in the cockpit and is in signal connection with the processor. The display device is configured to receive and display the around view image. The processor controls the display device to display a corresponding picture on the around view image according to the risk status of the construction vehicle.
