Train Schedule Editing System Authority Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing train diagram edit systems face difficulties in maintaining data consistency and user management when multiple users collaborate on creating and editing train operation data across networks, particularly in managing train lines and user authorities, which becomes complex when operations span across companies or countries.
Innovation Solution
A train diagram edit system with a diagram management server that unifies train line information and authority settings, allowing users to manage and edit train lines while maintaining user authentication and authority levels, enabling efficient data sharing and real-time updates, and facilitating coupling of train lines within the same or different departments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple users collaborate to create diagram data on a network, then the productivity of train schedule creation is improved, but the device complexity of managing user authorities and data consistency increases
Solution Approach 1:
The patent segments user authorities into distinct levels (creator, editor, manager) and assigns specific permissions to each level. This segmentation allows multiple users to collaborate simultaneously on different portions of the diagram data without conflicts, as each user operates within their authorized scope. The segmentation of authority levels directly resolves the contradiction by enabling high productivity through parallel collaboration while maintaining manageable complexity through structured permission hierarchies.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a centralized server that mediates all data access and modification operations. This intermediary enforces authority rules, manages version control, and ensures data consistency across multiple users. By placing this intermediary layer between users and the diagram data, the system enables collaborative productivity while the intermediary automatically handles the complexity of authority management and conflict resolution.
2Adaptability or versatility
If train lines are coupled across different departments or companies, then the adaptability of the system is improved, but the difficulty of detecting and measuring data consistency worsens
Solution Approach 1:
The patent implements feedback mechanisms that automatically detect and report data consistency issues when train lines are coupled across departments or companies. The system provides real-time feedback on authority conflicts, version mismatches, and data integrity problems. This feedback enables the system to adapt to cross-departmental coupling scenarios while automatically monitoring and alerting users to consistency issues, thereby resolving the contradiction between enhanced adaptability and increased detection difficulty.
Solution Approach 2:
The patent replaces manual verification methods with automated computational mechanisms for detecting data consistency. Instead of relying on users to manually check for conflicts when coupling train lines across different departments, the system employs automated algorithms that systematically verify data integrity, authority permissions, and schedule conflicts. This substitution transforms the difficult manual detection process into an efficient automated system that supports cross-departmental adaptability.
3Reliability
If detailed user authority information is stored for each train line, then the reliability of authority management is improved, but the quantity of data to be managed increases
Solution Approach 1:
The patent applies local quality by storing detailed authority information only where necessary - specifically for each train line's creator and associated users - rather than maintaining uniform detailed records for all system elements. This localized storage approach ensures reliable authority tracking for specific train lines while avoiding the proliferation of unnecessary data. The authority information is stored at the appropriate granularity level (per train line) rather than globally, thus maintaining reliability without excessive data quantity.

AI summary
Train lines can be effectively created, shared by a plurality of users. Upper users can edit the train lines created by general users and make engagement person change. A diagram management server stores user information defining a relationship between a login user and an authority level; train line information; and authority setting information defining a relationship between a creation person having edit authority of the train line and an upper user in database. When the login user is defined as upper user of the creation person in the authority setting, the diagram edit terminal requests register and update of the train line information created by the creation person based on authority level of the login user, and the diagram management server resisters and updates the train line information. Then, from database, the diagram edit terminal acquires the train line information that the login user has the edit authority, and displays the train line information.
