Solution Overview
Problem
The existing railway video surveillance systems face challenges in seamless interconnection and interworking among nodes of different non-standard protocols, requiring additional interface and protocol conversion modules, leading to increased equipment and maintenance costs, complex operations, and high personnel development requirements.
Innovation Solution
Implementing interconnection and interworking through a method that utilizes a correspondence relationship between ports and protocol versions, allowing direct communication between nodes using peer-to-peer protocol versions, eliminating the need for additional interface service or protocol conversion modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cascaded connection between different levels of nodes of different non-standard protocols is implemented in the interface plus protocol converter mode, then interconnection and interworking can be achieved, but interface service module and protocol conversion module are required, involving more intermediate modules and additional equipment investment cost
Solution Approach 1:
The patent extracts and eliminates the protocol conversion module from the traditional interface plus protocol converter architecture. By directly supporting multiple protocol versions in the core node and enabling peer-to-peer communication between access nodes and core nodes, the system removes the need for intermediate protocol conversion modules, thereby reducing device complexity while maintaining interconnection and interworking capability across different protocol versions
Solution Approach 2:
The core node is designed with multi-functionality to directly support multiple protocol versions (Document 630, Document 71, Document 575) simultaneously. The core node can identify and communicate with access nodes using their respective protocol versions without requiring external protocol conversion modules, making the core node a universal interface that handles diverse protocol requirements internally
2Adaptability or versatility
If cascaded connection between different levels of nodes of different non-standard protocols is implemented in the interface plus protocol converter mode, then interconnection and interworking can be achieved, but there are conventional problems like limitations of a single protocol proxy and step-by-step forwarding, and a constrained upgrading and retrofit hierarchical position under a three-level architecture mode
Solution Approach 1:
The patent segments the protocol handling function by allowing each access node to independently manage its own protocol version and directly establish connections with the core node. This eliminates the step-by-step forwarding limitation where a single protocol proxy would need to handle all protocol conversions sequentially. Each access node can operate with its specific protocol version (Document 630, Document 71, or Document 575) without constraining the overall system architecture
Solution Approach 2:
Instead of having the core node act as a single protocol proxy that converts between different protocols in a centralized manner, the patent inverts the approach by enabling access nodes to directly initiate and maintain connections with the core node using their native protocol versions. This peer-to-peer approach eliminates the constrained hierarchical positioning and simplifies the operation flow by removing the need for complex protocol translation steps
3Adaptability or versatility
If cascaded connection between different levels of nodes of different non-standard protocols is implemented in the interface plus protocol converter mode, then interconnection and interworking can be achieved, but interconnection and interworking of various levels of nodes involves a relatively complex operation flow, relatively high investment on personnel development and railway upgrading and retrofit, relatively high difficulties in troubleshooting, and relatively high daily maintenance cost
Solution Approach 1:
The access nodes are designed to autonomously identify the protocol version of the core node and automatically establish connections using the appropriate protocol. This self-service capability eliminates the need for complex manual configuration and personnel training in protocol conversion procedures. The system automatically handles protocol selection and connection establishment, reducing the investment required for personnel development and simplifying maintenance operations
