Solution Overview
Problem
Manual operation in marshaling yards is inefficient and unsafe, lacking automated systems to monitor and control ad-hoc train movements, leading to reduced safety and increased employee risk due to the absence of a comprehensive automatic monitoring system for identifying movable objects and obstacles.
Innovation Solution
A remote-controlled system utilizing laser scanners and high-resolution digital video cameras to electronically operate and monitor switch points, providing real-time visual indications to drivers through LED direction lights, enabling safer and more efficient route management by identifying movable objects and obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation is used in marshaling yards, then employees can control train movements, but safety is reduced and operational efficiency decreases
Solution Approach 1:
The patent replaces manual mechanical operations with an automated electronic control system that uses laser scanners to detect movable objects and LED direction lights to guide train movements, eliminating the need for manual switching point operation and significantly improving safety
Solution Approach 2:
The system enables self-service operation where the automated control system independently monitors train movements using laser scanners and automatically provides guidance through LED lights, reducing dependency on manual employee intervention while maintaining operational control
2Reliability
If traditional signaling systems are used, then train movements can be controlled, but the system is expensive and requires massive instrumentation
Solution Approach 1:
The patent extracts the essential function of object detection from complex traditional signaling systems and implements it using simpler, cheaper laser scanners that can identify movable objects, human factors, and obstacles without requiring massive instrumentation along the tracks
Solution Approach 2:
The system replaces expensive traditional signaling instrumentation with more economical laser scanners and LED direction lights that provide the necessary control capability at lower cost, making the system more economically viable for marshaling yard operations
3Measurement precision
If track circuit or axle counter systems are used for identification, then train objects can be identified, but the systems are very expensive and cannot identify human factors or obstacles
Solution Approach 1:
The patent implements a universal detection system using laser scanners that can identify not only train movable objects but also human factors and other obstacles in the track zone, providing comprehensive multi-functional detection capability that traditional systems lack
4Ease of operation
If manual route preparation is performed, then switching points can be operated, but route preparation time increases and control is lacking
Solution Approach 1:
The system implements real-time feedback through laser scanners that continuously monitor the track zone and automatically provide information about movable objects and route status, enabling rapid automated route preparation and eliminating the time-consuming manual preparation process while maintaining precise control
