Solution Overview

Problem

Existing railway installations face complexity in determining and managing control information for railway vehicles, leading to potential calculation errors and inefficiencies in transmitting steering information.

Innovation Solution

A method that centralizes the calculation of a railway vehicle's route within the interlocking system, which determines an identifier for a telegram associated with a next beacon, and transmits this identifier to the encoder connected to the beacon, simplifying the process and reducing errors by centralizing complex calculations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the encoder determines the piloting information locally, then the beacon can transmit driving information to the railway vehicle, but the determination process becomes complex and error-prone

Engineering Contradiction:
Improveaccuracy of piloting informationVSAvoidcomplexity of encoder structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex calculation function from the encoder and relocates it to the interlocking system. The encoder no longer performs route determination calculations but simply transmits pre-calculated piloting information from the interlocking system to the beacon, thereby simplifying the encoder structure while maintaining calculation accuracy.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The interlocking system acts as an intermediary between the central control and the encoder/beacon system. It receives route information from the central control, calculates the appropriate piloting information, and then transmits this information to the encoder, which forwards it to the beacon for transmission to the railway vehicle.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the encoder performs complex calculations to determine piloting information, then driving information can be transmitted to the railway vehicle, but calculation errors may occur

Engineering Contradiction:
Improveefficiency of traffic managementVSAvoidaccuracy of route calculation
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent extracts the complex calculation function from the encoder and relocates it to the interlocking system, which has a more comprehensive view of railway traffic. This centralization of calculation functions improves both the efficiency of traffic management and the accuracy of route calculations by preventing calculation errors at the encoder level.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system implements feedback mechanisms where the interlocking system continuously monitors railway traffic conditions and adjusts piloting information accordingly. This feedback loop ensures that the most accurate and up-to-date route information is transmitted to the railway vehicle, improving both productivity and reliability.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the interlocking system centralizes calculation of piloting information, then transmission process is simplified and errors reduced, but the interlocking system must have comprehensive traffic view

Engineering Contradiction:
Improvesimplicity of transmission processVSAvoidinformation processing requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the calculation and transmission functions into a unified process at the interlocking system level. The interlocking system both calculates the piloting information and transmits it to the encoder, eliminating the need for the encoder to perform separate calculation operations and simplifying the overall transmission process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The interlocking system is designed to perform multiple functions: it monitors railway traffic conditions, calculates piloting information for multiple routes, manages multiple encoders and beacons, and coordinates train movements. This multi-functionality allows it to handle comprehensive traffic information while maintaining a simplified transmission process.

Inventive Principle:
Principle #6Universality (Multi-functionality)
