Solution Overview
Problem
Existing methods for data transmission in cable car installations, such as underground and aerial cables, face challenges including high costs, environmental protection issues, and maintenance requirements, particularly in mountainous regions.
Innovation Solution
A method where data from secondary stations is split into packets marked for specific nodes, transmitted along a segmented path with nodes, and collected at the primary station, allowing for wireless directional radio communication without direct transfer, enabling efficient data capture and transmission from all nodes without extensive infrastructure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If underground cables are laid from support to support, then reliability is improved and maintenance requirements are reduced, but costs increase and environmental protection is compromised
Solution Approach 1:
The patent replaces the mechanical cable laying system with a wireless data transmission system using directional radio. Instead of physically installing underground cables between supports, the system uses radio waves to transmit data wirelessly from each support to the primary station, eliminating the need for extensive ground works while maintaining data transmission functionality
Solution Approach 2:
The patent divides the data transmission path into segments, with each support transmitting data independently to the primary station. Data from the secondary station is split into packets, each marked for specific nodes, and transmitted along segmented paths through intermediate supports to the primary station, allowing parallel transmission without requiring a single continuous cable
2Reliability
If aerial cables are stretched between supports, then data transmission capability is improved, but costs increase due to stronger anchor requirements and maintenance involvement increases
Solution Approach 1:
The patent replaces the mechanical aerial cable system with a wireless radio transmission system. Instead of stretching physical cables between supports that require anchoring and protection from environmental influences, the system uses directional radio waves that pass through the air without physical contact, eliminating maintenance requirements associated with cable protection and weather resistance
3Ease of manufacture
If wireless directional radio is used for data transmission, then costs are reduced and environmental impact is minimized, but data transmission reliability may be affected by surrounding signals
Solution Approach 1:
The patent applies directional radio antennas at each support that are oriented to transmit and receive signals only from specific directions. Each antenna has a focused beam pattern that provides high gain in the desired direction while rejecting signals from other directions, creating localized communication channels that are immune to surrounding interference
Solution Approach 2:
The patent uses intermediate supports as relay stations that receive data packets from one support and forward them to the primary station. Each intermediate support acts as a mediator in the transmission path, with directional antennas that selectively receive signals from the previous support and transmit to the next, creating a controlled transmission path that filters out surrounding signals
4Adaptability or versatility
If data is transmitted through multiple nodes along a segmented path, then flexibility and adaptability are improved, but data transmission time increases
Solution Approach 1:
The patent segments the data transmission path into parallel channels, with each support transmitting data independently to the primary station. Data packets are divided and routed through different intermediate supports simultaneously, allowing parallel transmission that reduces overall transmission time while maintaining the flexibility of the segmented architecture
Solution Approach 2:
The patent implements preliminary routing decisions at each support, where data packets are marked with destination information and forwarded along predetermined paths. Each support has pre-configured directional antennas and transmission parameters optimized for the specific path, eliminating the need for real-time routing decisions and reducing transmission delays
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method allows for reliable and cost-effective data transmission from all nodes in a cable car installation, reducing maintenance needs and environmental impact, while ensuring timely data arrival and operational integrity.
Implementation Method 1
it would suffice if a support is able to set up a data connection to the respective adjoining supports or the adjoining station. It is thus possible for the method, in a preferred development, to be performed by means of a wireless data connection, in particular directional radio.
Data Source
AI summary
Data are transmitted from a secondary station to a master station along a segmented path, wherein two contiguous segments are respectively connected by a node and wherein the path has at least three segments with at least two nodes. The data from the secondary station are split into N data packets, where N is the number of nodes. The data packets are marked distinguishably, each marking corresponding to a particular node on the path. Each data packet along the path is forwarded only to the adjacent node or adjacent station. Each node checks to determine whether the marking of the packet corresponds to the respective node. If so, data from the node are added to the data packet. The data packets are collected in the master station. The data transmission is concluded successfully if all N data packets with data from all N nodes are present.
