SNS-II加速器控制网络管理系统设计与实现

Background]: The increasing scale and complexity of large scientific facilities have led to significant challenges in control networks, including a proliferation of connected devices, security management difficulties, and inefficient maintenance processes. [Purpose]: To address these challenges, a comprehensive control network management system was designed and implemented, specifically tailored for large-scale accelerator facilities. [Methods]: The developed system integrates three core functionalities: unified IP address management, dynamic network information acquisition, and network access control. A centralized application and approval mechanism was implemented to eliminate IP conflicts. Real-time monitoring of device status and precise physical location identification were achieved through continuous collection of switch operation data. Network security was enhanced through an IP-port binding scheme that strictly controls access to the control network. The system architecture employs a web-based approach with a Vue.js frontend framework, a hybrid Node.js and Python backend technology stack, and MongoDB for data persistence. [Results]: The system has been successfully deployed and is running stably in the CSNS accelerator control network. It effectively resolves security vulnerabilities and maintenance challenges in network management. [Conclusions]: The implemented management system significantly enhances both the operational security and maintenance efficiency of accelerator control networks. It establishes a robust foundation for CSNS-II network management and offers a promising solution for improving control network administration across various large-scale scientific facilities.
