Security Inspection Terminal Peer-to-Peer Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security inspection network systems are vulnerable to failures as they rely on a central server for operation, leading to system breakdowns if the server malfunctions or if network links are disconnected, even if security inspection devices and workstations remain operational.
Innovation Solution
Implementing a security inspection terminal that can search for and connect with other terminals within the network, allowing direct communication between security inspection devices and workstations without relying on a server, and utilizing correspondence relationship information to establish connections and synchronize data when the server is unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a central server is used to manage security inspection data, then system operation is simplified and data management is centralized, but the system becomes vulnerable to server failures and network disconnections
Solution Approach 1:
The patent divides the centralized server-based system into distributed peer-to-peer segments. Each terminal device maintains local data storage and can independently communicate with other terminals, breaking the single point of failure into multiple independent operational units that can function autonomously.
Solution Approach 2:
The patent introduces correspondence relationship information as an intermediary mechanism that enables indirect communication between terminals. When direct communication is unavailable, terminals use stored correspondence data to establish alternative communication paths, maintaining system operation without requiring constant server mediation.
2Reliability
If direct peer-to-peer communication is implemented between terminals, then fault tolerance improves and system reliability increases, but device complexity increases due to need for searching and connection management
Solution Approach 1:
The patent performs preliminary actions by pre-storing correspondence relationship information in each terminal before actual communication needs arise. This advance preparation eliminates the need for complex real-time discovery and connection establishment, reducing operational complexity while maintaining reliable peer-to-peer communication paths.
3Reliability
If the system continuously monitors server availability and switches to peer-to-peer mode, then system reliability improves during server failures, but loss of time occurs during detection and switching processes
Solution Approach 1:
The patent performs preliminary configuration of correspondence relationship information during system initialization or idle periods, so that when server failure occurs, terminals already have the necessary connection data ready. This eliminates time delays associated with real-time discovery and switching, enabling immediate transition to peer-to-peer mode.

AI summary
The present invention discloses a security inspection terminal, a security inspection network system and a security inspection data transmission method and relates to the field of security inspection. The security inspection data transmission method comprises: searching step of searching for a second security inspection terminal which can be accessed by a first security inspection terminal; connecting step of connecting said first security inspection terminal to said second security inspection terminal which can be accessed by said first security inspection terminal; and transmitting step of transmitting security inspection data between said first security inspection terminal and said second security inspection terminal which can be accessed by said first security inspection terminal. The present invention proposes a security inspection network solution without taking a server as center. In the solution, the security inspection terminals can be inter-connected by extending the function of the security inspection terminal , so the fault-tolerance capability of the system is increased and stability and reliability of the system is improved.
