Tractor-Mounted Trailer Door Status Detection Before Dock Maneuvering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rear doors of trailers pose a hazard when unlatched during maneuvering, potentially causing damage and requiring additional maneuvering to resolve at loading docks.
Innovation Solution
A door status monitor on a tractor uses cameras, LIDAR, and RADAR to detect the status of hitched and nearby trailer doors through a neural network, allowing autonomous detection and prevention of unlatched doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the tractor manually checks trailer door status at the loading dock, then the door status can be confirmed, but time is wasted and additional maneuvering is required
Solution Approach 1:
The system performs door status detection using sensors and neural networks before the tractor begins maneuvering the trailer. This preliminary detection allows the tractor to identify unlatched doors in advance, preventing the need for additional stopping and maneuvering at the loading dock, thereby saving time while maintaining accurate door status verification
2Productivity
If the tractor maneuvers the trailer without detecting door status, then maneuvering efficiency is maintained, but safety hazards occur from swinging doors
Solution Approach 1:
The system continuously monitors door status during trailer maneuvering using sensors and neural network processing. When unlatched doors are detected, the system provides feedback to the tractor controller, which automatically adjusts maneuvering parameters or stops movement to prevent door swinging hazards, thereby maintaining both safety and operational efficiency
Solution Approach 2:
The door status detection system operates autonomously without requiring manual intervention. The sensors, neural network, and controller work together to automatically detect door status, assess safety risks, and adjust maneuvering operations, enabling the system to serve itself while maintaining high safety standards during trailer transportation
3Measurement precision
If multiple sensors and neural networks are deployed for door detection, then detection accuracy improves, but system complexity increases
Solution Approach 1:
The system combines multiple sensor types (cameras, LIDAR, RADAR) and neural network processing into an integrated door status detection system. By merging these components and processing their data through a unified neural network framework, the system achieves high detection accuracy while managing complexity through centralized control and coordinated operation of all sensors
Data Source
AI summary
A door status monitor determines a status of a rear door of a trailer from a tractor. The door status monitor receives an input source including information of the trailer. The input source includes at least one of an image, a LIDAR point cloud, and a RADAR point cloud from at least one of a camera, a LIDAR, and a RADAR, respectively, mounted to the tractor and having a view that includes at least a rear of the trailer. A door status monitor processes the input source through a neural network trained to generate a trailer door status defining the status of the rear door of the trailer. A door status monitor outputs the trailer door status.
