[0002] With the deepening of Industry 4.0 and intelligent manufacturing, the types of equipment in industrial fields are increasing, and communication protocols are becoming more complex and diverse. Traditional industrial communication systems face severe challenges in dealing with complex technical issues such as multi-protocol integration, system latency, and reliability. Existing systems typically use hard coding to achieve protocol conversion, resulting in poor system scalability, long access cycles for new protocols, and difficulty in adapting to rapidly changing industrial application needs.

[0003] In terms of real-time performance and reliability, traditional communication architectures mostly adopt synchronous blocking communication mechanisms, resulting in generally high system latency. Furthermore, they lack effective automatic fault tolerance and recovery methods when facing network fluctuations or equipment failures, which seriously affects the system stability in scenarios such as robot scheduling and real-time control. In addition, existing systems are often tightly coupled with specific hardware platforms, lacking flexible plug-and-play deployment capabilities, leading to high system upgrade and maintenance costs and low resource utilization.
