Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication fault detection methods in digital broadcasting networks consume significant server resources, affecting server fluency and sound quality, leading to system instability, especially during sudden failures.
Innovation Solution
A hot backup switching method and system based on network card detection, where a slave server sends query instructions to a master server at preset intervals, and upon failure, performs seamless switching using GPS synchronization for timestamp alignment, ensuring continuous audio playback without resource-intensive upper-layer platform intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional communication fault detection methods are used, then system reliability is improved, but server resource consumption increases and system stability deteriorates
Solution Approach 1:
The patent introduces a dedicated fault detection module as an intermediary component that handles communication fault detection separately from the main server processing. This module operates independently to monitor network card status and trigger hot backup switching, thereby protecting the main server resources while maintaining system reliability through continuous fault detection.
Solution Approach 2:
The system is segmented into distinct functional modules: a fault detection module that monitors network communication status, a hot backup module that manages standby servers, and the main playback server. This segmentation allows fault detection to occur without burdening the main server resources, as each module operates independently with its own resource allocation.
2Measurement precision
If communication fault detection is performed with high requirements, then fault detection precision is improved, but server fluency and sound quality deteriorate
Solution Approach 1:
The fault detection module serves as an intermediary that performs precise communication status monitoring without interfering with the main audio processing pipeline. It uses dedicated network cards and independent detection mechanisms to achieve high detection precision while leaving the main server's audio processing resources unaffected, thus maintaining server fluency and sound quality.
Solution Approach 2:
The system separates fault detection functions from audio processing functions into distinct modules. The fault detection module uses its own network interface and processing resources to perform precise communication monitoring, while the audio processing module maintains its dedicated resources for high-quality sound output, ensuring both detection precision and audio quality are preserved.
3Reliability
If hot backup switching is implemented, then system stability is improved, but device complexity increases
Solution Approach 1:
The hot backup system is segmented into modular components: a primary playback server, a standby server, a fault detection module, and a switching control module. Each module has a specific function and can be independently configured and managed. This modular segmentation reduces overall system complexity by allowing independent optimization and maintenance of each component while providing stable hot backup functionality.
Solution Approach 2:
The fault detection module and hot backup module operate autonomously with predefined switching criteria. When communication faults are detected, the system automatically triggers the hot backup switching mechanism without requiring manual intervention. This self-service capability simplifies operation and reduces the complexity of system management while maintaining high stability through automatic failover.

AI summary
A hot backup switching method and system based on network card detection. The method includes the following steps: S1: driving a first synchronous network card to send a query instruction to a second synchronous network card according to a preset time interval; S2: determining whether the first synchronous network card obtains a response packet sent by a master server device, if yes, executing S1; and if not and executing S3; S3: determining whether the working mode of the playback terminal belongs to a master mode; and if yes, and executing S4; and S4: determining whether the second synchronous network card responds, if yes, executing S1. Hot backup switching is implemented by means of the network cards of the master server device and the slave server device, and seamless switching and continued playback are realized.
