Solution Overview

Problem

Existing vehicle communication systems require manual configuration of gateways and antennas, which is time-consuming and inefficient, especially when vehicle formations change, and there is a need for automated and efficient connection management of antenna units to a wireless local area network.

Innovation Solution

A method for controlling antenna unit connections to a wireless local area network that involves obtaining and comparing characteristics of external antenna units with predetermined criteria to determine if they are located on the vehicle, allowing or denying network access based on these criteria, including signal strength, signal-to-noise ratio, age of beacons, GNSS location, and vehicle information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual configuration of gateways and antennas is used, then connection reliability can be established, but installation time and operational complexity increase significantly

Engineering Contradiction:

Improveconnection reliabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The antenna units automatically perform configuration and connection establishment by comparing their own characteristics (ID, signal strength, location) with predetermined criteria. The system self-configures without manual intervention, allowing gateways and antennas to autonomously establish reliable connections while reducing installation time.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Predetermined characteristics and criteria are established before the antenna units are deployed or connected. This preliminary configuration of expected parameters (such as valid antenna IDs, signal strength thresholds, and location criteria) enables rapid automated connection validation without requiring manual setup during installation.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If manual configuration of gateways is performed, then proper network setup is achieved, but adaptability to vehicle formation changes deteriorates

Engineering Contradiction:

Improvenetwork setup accuracyVSAvoidadaptability to vehicle formation changes

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts to changing vehicle formations by continuously monitoring antenna characteristics and automatically adjusting connections. When vehicle segments are reconfigured or new carriages are added, the antenna units automatically compare their characteristics with predetermined criteria and establish or terminate connections accordingly, maintaining network reliability without manual reconfiguration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms where antenna units continuously report their characteristics (location, signal strength, ID) to the network. The network uses this feedback to verify whether antennas meet predetermined criteria and automatically adjusts connections, enabling real-time adaptation to vehicle formation changes while maintaining proper network setup.

Inventive Principle:

Principle #23Feedback

3Productivity

If automated connection control is implemented, then installation efficiency improves, but system complexity increases

Engineering Contradiction:

Improveinstallation efficiencyVSAvoidconnection control system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical configuration processes with automated electronic comparison and control. Instead of physically configuring gateways and antennas manually, the system uses automated comparison of antenna characteristics (ID, signal strength, location) with predetermined criteria stored in memory, significantly improving installation efficiency while the electronic control logic manages the increased system complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Measurement precision

If characteristic comparison with predetermined criteria is performed, then connection accuracy improves, but processing requirements increase

Engineering Contradiction:

Improveconnection validation accuracyVSAvoidprocessing energy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system performs comparison of essential antenna characteristics (ID, signal strength, location) with predetermined criteria rather than analyzing all possible parameters. This partial action approach achieves sufficient connection validation accuracy while minimizing processing energy consumption by focusing only on the most critical characteristics needed for reliable connection determination.

Inventive Principle:

Principle #16Partial or excessive action
