Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security inspection systems require manual effort and additional network devices for switching between operation and backup servers, resulting in a complex and costly process.
Innovation Solution
An automatic switching method and system that allows the operation server to switch its configuration and notify the backup server to take over, enabling seamless service continuity without manual intervention, using an automatic switching device to monitor and manage the switching process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual switching between operation server and backup server is implemented, then service continuity is maintained, but switching time is prolonged and operation efficiency is reduced
Solution Approach 1:
The patent applies preliminary action by pre-configuring the backup server with hot-standby status and pre-establishing network device configurations. When switching is needed, the backup server is already prepared to take over immediately, eliminating manual configuration time and reducing switching duration while maintaining service continuity.
2Reliability
If additional network devices and uncommon client terminals are added for switching, then server redundancy is achieved, but device complexity and system cost increase
Solution Approach 1:
The patent applies universality by designing the backup server to share the same network device configuration as the operation server. The network device can dynamically switch between serving the operation server and the backup server, eliminating the need for dedicated network devices for each server and reducing overall system complexity while maintaining redundancy.
Solution Approach 2:
The patent merges the network infrastructure by allowing a single network device to serve both operation and backup servers through dynamic configuration switching. This consolidation reduces the number of network devices required and simplifies the overall system architecture while preserving server redundancy capabilities.
3Ease of operation
If manual switching operation is performed, then configuration changes are controlled, but operation complexity and manual effort increase
Solution Approach 1:
The patent applies self-service by implementing automatic detection mechanisms that monitor operation server status and trigger switching operations automatically when failures are detected. The system performs self-diagnosis and self-switching without requiring manual intervention, simplifying the switching operation while maintaining controlled configuration changes through pre-established rules.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors server status and automatically initiates switching when failure conditions are detected. This closed-loop feedback system replaces manual switching operations with automated responses, reducing operational complexity while ensuring controlled and timely configuration changes.

AI summary
The present disclosure relates to an automatic switching method and an automatic switching system. The automatic switching method includes: an automatic switching device monitoring in real time a service state of an operation server; when the automatic switching device monitors that the operation server has terminated providing service for a client terminal, the automatic switching device sending to the operation server a switching instruction for switching a current configuration of the operation server and sending to a backup server a notification message for switching a current configuration of the backup server; and the backup server switching the current configuration of the backup server to a preset first configuration according to the notification message, and providing service for the client terminal; wherein the first configuration is the configuration of the operation server when the operation server provided service. In the automatic switching method and the automatic switching system provided by the present disclosure, the number of devices in the system can be reduced, the system can has be less complicated. The switching operation can be completed automatically, and the whole switching process is highly efficient and safe, improving the operation efficiency.
