Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for train operations lack real-time communication of passenger boarding ratios and relative positions of preceding or following trains, relying heavily on operator experience and skill for timely operations, and do not effectively process and display ever-changing train information to support optimal operations.
Innovation Solution
A system that transmits real-time onboard information from a train to the ground, where it is merged with ground information to calculate and display optimum operating conditions, using a wireless network to communicate these conditions back to the operator, allowing for precise and punctual operations by processing and narrowing down appropriate conditions based on traveling conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time onboard information is transmitted to ground and merged with ground information for automatic computations, then operations precision and timetable adherence are improved, but system complexity and information processing requirements increase
Solution Approach 1:
The system divides information processing into two segments: onboard information collection (speed, position, boarding ratio) and ground-based computation (merging onboard data with ground information, timetable comparison, operating condition determination). This segmentation allows complex processing to occur on the ground while keeping onboard equipment relatively simple.
Solution Approach 2:
A wireless communication network acts as an intermediary between the train and ground control center, enabling real-time information exchange without requiring complex direct integration. The ground control center serves as a mediator that processes onboard information and generates optimized operating conditions.
2Speed
If real-time information processing and display is implemented, then operator decision-making speed is improved, but information processing time and computational load increase
Solution Approach 1:
The system pre-calculates and stores optimal operating conditions based on various scenarios (boarding ratios, train positions, timetable requirements) before they are needed. When real-time data is received, the system quickly matches current conditions against pre-computed solutions rather than calculating from scratch, significantly reducing processing time.
Solution Approach 2:
The system implements continuous feedback loops where onboard information is transmitted to ground, processed, and optimized operating conditions are fed back to the operator in real-time. This closed-loop feedback enables rapid iterative adjustments to maintain timetable adherence while keeping processing cycles short through automated computations.
3Measurement precision
If comprehensive onboard information (speed, position, boarding ratio) is collected and transmitted, then operations support accuracy is improved, but data transmission volume and processing requirements increase
Solution Approach 1:
The system extracts only the most critical operational parameters (speed, position, boarding ratio) from the train's comprehensive data set for transmission to ground. Non-essential data is filtered out, reducing transmission volume while maintaining sufficient accuracy for operations support decisions.

AI summary
As a system for notifying a train operator of support information for operating a train 101 according to a schedule, there is technology for supporting train operations by displaying the location and speed of the train 101 on a running curve that accords with the operations schedule of the train 101. However, the prior art does not take into account displaying, in real-time, operations support information to the operator. Therefore, technology for processing ever-changing train traveling information, and creating and displaying in real-time operations support information has not been disclosed. Hence, the present invention transmits onboard information in real-time from a train 101 to a ground apparatus 102. The ground apparatus 102 is configured to perform computations by merging the onboard information with ground information, to calculate optimum operating conditions, and to display this information on a monitor 113 for the operator via a network 105.
