Autonomous Trailer Authentication for Secure Warehouse Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing automatic transportation system between logistics bases fails to restrict access of tractors to specific trailers and manage trailer information individually, leading to unauthorized trailer transport.
Innovation Solution
A system involving a control server that transmits trailer position information to autonomous tractors and a trailer managing device, which identifies and authenticates tractors through surrounding images, ensuring only allocated trailers are transported by authenticating tractors and managing their positions and identities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the automatic transportation system allows any tractor to access any trailer, then the ease of operation is improved, but the security and authorization control deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-registering tractors and trailers, establishing authorization relationships in advance. The control server stores registration information and uses it to authenticate future coupling attempts, preventing unauthorized access before it can occur.
Solution Approach 2:
The system implements feedback mechanisms where the control server continuously monitors coupling requests, compares them against registered authorization data, and provides real-time authentication decisions. This closed-loop control ensures that only authorized tractor-trailer combinations can couple.
2Reliability
If the system implements individual trailer management and access restriction, then the security is improved, but the device complexity increases
Solution Approach 1:
The control server performs multiple functions including registration, authentication, information management, and monitoring within a single system. This multi-functional approach provides comprehensive security without requiring separate specialized devices for each function, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The control server acts as an intermediary between tractors and trailers, managing all authorization and information exchange centrally. This mediator approach simplifies the system architecture by consolidating control logic in one component rather than distributing complex authentication mechanisms across multiple devices.
3Reliability
If the system authenticates tractors before transmitting trailer position information, then the security is improved, but the loss of time increases
Solution Approach 1:
The system performs preliminary authentication by verifying tractor identity and authorization status before transmitting trailer position information. This pre-verification ensures security while the efficient lookup of registration data minimizes the time required for authentication.

AI summary
A system and a method for controlling logistics transportation includes a control server to transmit position information of a trailer to an autonomous tractor, and a trailer managing device to receive information on an identification of the autonomous tractor from the control server and to open a door of a warehouse corresponding to the position information of the trailer, when information on an identification of an autonomous tractor, which is extracted from a surrounding image of the warehouse corresponding to the position information of the trailer is matched with the received information on the identification of the autonomous tractor.
