Solution Overview
Problem
Existing mobile network participants in multi-segment communication networks face complexity and cost issues due to the need for seamless signal strength across large spatial areas, particularly in electric monorail systems, where efficient handover between network segments is challenging.
Innovation Solution
A mobile network participant with slave and master modems, contact arrangements, and a redundancy protocol (PRP) enables efficient communication by overlapping segments, allowing for seamless handover and redundant data transmission, reducing system complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the network is segmented to maintain signal strength across large spatial areas, then signal strength is improved, but device complexity increases due to the need for handover mechanisms between segments
Solution Approach 1:
The network is divided into multiple segments with segment boundary arrangements that have overlaps. Each segment is served by a dedicated master modem, allowing the mobile network participant to communicate with multiple segments simultaneously through multiple slave modems, thereby maintaining signal strength while managing complexity through structured division
Solution Approach 2:
The mobile network participant is equipped with multiple slave modems before entering a segment boundary arrangement. When approaching a segment boundary, the system proactively establishes connections with master modems in adjacent segments through the overlap area, enabling seamless handover without interrupting communication
2Reliability
If multiple slave modems are provided for communication with multiple master modems, then communication reliability is improved, but hardware complexity and costs increase
Solution Approach 1:
Multiple slave modems are combined within a single mobile network participant, sharing common control logic and resource management. The segment boundary arrangement integrates multiple communication paths into a unified structure, allowing redundant communication channels to coexist without proportionally increasing overall system complexity
Solution Approach 2:
The system changes the operational parameters of slave modems dynamically based on position and connection status. Modems can be activated or deactivated depending on which segments are currently accessible, allowing the system to maintain high reliability through multiple modems while reducing hardware complexity by not requiring all modems to operate simultaneously at full capacity

AI summary
The invention relates to a movable network participant (10) for use in a wired network (1), in particular in a conductor network of an electric monorail, wherein the wired network (1) has at least one first segment (S1), one second segment (S2) and one segment boundary arrangement (12), and wherein the movable network participant (10) is provided for movement along the segments (S1, S2).To specify a mobile network participant (10), a segment arrangement, a method and a modem arrangement that enable switching between two segments of a network simply and efficiently, a mobile network participant is proposed, among other things, which has a first slave modem (SM1), a second slave modem (SM2), a first contact arrangement (K1) and a second contact arrangement (K2), wherein the slave modems (SM1, SM2) are provided for communication with at least one first master modem (MM1) and/or one second master modem (MM2) via the contact arrangements (K1, K2) and the segments (S1, S2).The segments (S1, S2) have an overlap (120) in the area of the segment boundary arrangement (12), wherein the contact arrangements (K1, K2) of the movable network participant (10) are arranged such that in the area of the overlap (120) of the segments (S1, S2) the first contact arrangement (K1) is at least partially connected to one of the segments (S1, S2) and the second contact arrangement (K2) is at least partially connected to another of the segments (S1, S2).
