Transfer Zone Access Control for Barrier-Free Container Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handling systems for transport vehicles in container terminals face challenges in ensuring safe operation within transfer zones, particularly in preventing collisions between manually guided and automatically guided vehicles, which often require physical barriers that are costly and inefficient to maintain.
Innovation Solution
A control system that automatically intervenes in the vehicle control of transport vehicles to prevent entry into transfer zones without authorization, using a safety controller and vehicle controller to manage access and define secure transfer areas, allowing for barrier-free zones and improved handling capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical barriers are installed to prevent unauthorized entry into transfer zones, then safety is improved, but device complexity and infrastructure costs increase
Solution Approach 1:
The patent replaces physical mechanical barriers with an electronic control system that automatically intervenes in vehicle control. The control system monitors vehicle positions and automatically prevents unauthorized entry into transfer zones, eliminating the need for physical fences or barriers while maintaining safety.
Solution Approach 2:
The patent introduces a control system as an intermediary between vehicles and transfer zones. This intermediary automatically manages access by detecting vehicle positions and controlling entry authorization, replacing the need for physical infrastructure while ensuring safe operation.
2Reliability
If physical barriers are installed to separate manual and automated areas, then collision prevention is improved, but maintenance costs and operational efficiency deteriorate
Solution Approach 1:
The patent replaces physical separation barriers with an automated control system that manages vehicle movement. The system dynamically controls access to transfer zones based on real-time vehicle positions and authorization status, eliminating maintenance requirements and improving operational efficiency while preventing collisions.
Solution Approach 2:
The patent implements a dynamic control system that adapts access authorization based on real-time conditions. The control system continuously monitors vehicle positions and adjusts entry permissions dynamically, allowing flexible and efficient operation without the rigidity of fixed physical barriers.
3Reliability
If physical barriers are used to define transfer zones, then safety is improved, but ease of operation and flexibility deteriorate
Solution Approach 1:
The patent replaces fixed physical barriers with a flexible electronic control system. The control system defines transfer zones through virtual boundaries and manages access through automated authorization, allowing easy reconfiguration of zone boundaries and access rules without physical construction or demolition.
Solution Approach 2:
The patent uses parameter-based control to define and manage transfer zones. The control system adjusts operational parameters such as entry authorization, vehicle positions, and zone boundaries dynamically, providing operational flexibility while maintaining safety through automated enforcement of control parameters.

AI summary
The invention relates to a method for controlling travel within a transfer zone (C) for containers (2) of transport vehicles, in particular straddle carrier devices (7a, 7b), the transfer zone (C) connecting an automatic region (A) for automatically guided transport vehicles to a manual region (B) for manually guided transport vehicles, and the transport vehicles travelling through the transfer zone (C) in order to deliver or pick up containers (2) in the transfer zone (C), the transport vehicles being granted or refused authorisation to enter the transfer zone (C) in order to travel through the transfer zone (C). In order to improve a method of this kind, according to the invention, in the absence of granted authorisation for entry of a manually guided transport vehicle, in particular a straddle carrier device (7b), in a transfer region (X) of the transfer zone (C), an intervention is implemented automatically in a vehicle controller (9) of the transport vehicle in such a way that at least full entry, but preferably even partial entry, to the transfer zone (C) is prevented. The invention also relates to a control system for carrying out a method of this kind, and to a terminal (1) for containers (2) comprising a control system of this kind.
