Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining locomotive operation speed, direction, and displacement are costly and difficult to implement, especially when new equipment is added, due to interface saturation and access restrictions to public platforms, and they lack the accuracy provided by advanced satellite positioning technologies.
Innovation Solution
A locomotive operation state detection method using satellite positioning, which involves installing a satellite positioning module to acquire real-time position, speed, and direction information, and categorizing states as initial, invalid, low speed, and credible speed to calculate speed, direction, and displacement based on valid positioning data, reducing the need for interfacing with existing systems and minimizing maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional speed sensors and public platforms are used to acquire locomotive information, then the information can be obtained, but the interface cost and construction difficulty are very high
Solution Approach 1:
The patent replaces traditional mechanical sensors and platform interfaces with satellite positioning technology. The satellite positioning module directly provides position, speed, and direction information without requiring complex interfaces with locomotive systems, thereby reducing interface complexity while maintaining detection accuracy.
Solution Approach 2:
The patent introduces satellite positioning as an intermediary system that externally provides locomotive operation information. Instead of directly interfacing with the locomotive's internal systems, the satellite positioning module acts as a mediator to acquire information from external space-based infrastructure, simplifying the overall system architecture.
2Adaptability or versatility
If new equipment is added to the locomotive to acquire information, then more detection capabilities are achieved, but the construction difficulty and cost increase significantly
Solution Approach 1:
The satellite positioning module serves multiple detection functions simultaneously - it provides position information, speed calculation, and direction determination all through a single device. This multi-functionality eliminates the need for separate sensors and systems, reducing construction difficulty while enhancing detection capabilities.
Solution Approach 2:
The patent uses satellite positioning data as a copy or representation of the locomotive's actual operation state. Instead of directly measuring speed and direction through complex mechanical sensors, the system uses satellite-derived positional data to calculate these parameters, simplifying the detection system while maintaining accuracy.
3Loss of information
If public platforms are accessed to obtain locomotive information, then information can be acquired, but access permission and interface costs are issues
Solution Approach 1:
The patent extracts the information acquisition function from the complex public platform infrastructure and relocates it to a standalone satellite positioning module. This extraction eliminates the need for platform access permissions and interfaces, directly providing the required locomotive information without intermediary access barriers.
