Autonomous Vehicle Access Control Using Worker Entry-Exit Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-driving device control systems require workers to perform multiple operations and carry multiple keys to enter and exit an entry restricted area, leading to increased operational complexity and potential safety risks.
Innovation Solution
A self-driving device control system that includes outside and inside identification devices at entrances to acquire worker identification information, a storage device to store this information, and a control device to manage the self-driving devices based on entry and exit identification, ensuring all workers have exited before resuming operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a worker presses the automatic stop button to stop the transport vehicle and removes a monitoring key to enter the entry restricted area, then worker safety is enhanced by preventing vehicle resumption while workers are present, but the operational complexity increases due to multiple operations and multiple keys required
Solution Approach 1:
The patent replaces the mechanical key-based access control system with an optical identification system. Workers present identification cards that are read by optical readers at entrances, eliminating the need for physical monitoring keys and manual stop button operations. This substitution reduces operational complexity while maintaining safety through automated identification and tracking of workers in the restricted area.
Solution Approach 2:
The system enables workers to independently enter and exit the entry restricted area by simply presenting their identification cards at the automated entrances. The control device automatically processes entry and exit information, manages vehicle stoppage and resumption, and tracks worker presence without requiring workers to perform multiple manual operations or carry specialized keys.
2Reliability
If multiple monitoring keys are provided for workers to carry and use, then worker safety is ensured through key-based access control, but the device complexity increases due to multiple keys and key mounting sections
Solution Approach 1:
The patent implements a universal identification card system that serves multiple functions: worker identification, area access authorization, and presence tracking. A single identification card replaces multiple monitoring keys, and the automated optical reading system at entrances handles multiple workers simultaneously, reducing both device complexity and operational burden while maintaining comprehensive safety control.
Solution Approach 2:
The patent replaces the mechanical key mounting section and physical key interaction system with an optical identification card reading system. The control device automatically captures and processes identification information from cards presented at entrances, eliminating the need for physical key insertion, removal, and manual monitoring, thereby reducing system complexity while maintaining access control functionality.
3Reliability
If the control device monitors each worker's entry and exit individually through key operations, then worker safety is maintained by tracking presence, but the loss of time increases due to multiple manual operations required for each entry and exit
Solution Approach 1:
The system continuously and automatically monitors worker presence in the entry restricted area through uninterrupted optical scanning of identification cards at entrances. Entry and exit information is captured in real-time without requiring workers to pause their activities for manual key operations, thereby maintaining accurate presence tracking while eliminating time loss associated with multiple manual steps.
Solution Approach 2:
The patent replaces time-consuming manual key operations with rapid optical identification card reading. The automated system captures worker identification information instantaneously as workers approach entrances, processes entry and exit data without interruption to worker flow, and continuously updates the control device with current presence information, thereby maintaining safety monitoring while dramatically reducing the time required for entry and exit operations.

AI summary
A self-driving device control system of the present invention includes an entry restricted area, at least one entrance opened and closed by a closing member, a self-driving device, and a control device, and further includes an outside identification device, an inside identification device, and a storage device. When identification information is acquired by the outside identification device, the control device sets the self-driving device to a stopped state. If the storage device is not storing even one piece of entry identification information regarding a worker for which a corresponding piece of exit identification information regarding the same worker is not stored in the storage device, and furthermore all of the entrances are in a passage restricted state, the control device resumes the driving of the self-driving device.
