基于鸿蒙的EAST中央控制系统设计与实现

Design and Implementation of the EAST Central Control System Based on HarmonyOS

摘要: 针对EAST中央控制系统存在的通信协议不统一、实时性不足以及对国外系统依赖度高等问题，本文设计并实现了一种基于鸿蒙操作系统(HarmonyOS)的EAST中央控制系统。系统通过对EPICS IOC进行容器化部署，并引入WebSocket双向通信机制，实现了系统架构与通信模式的升级与优化。为进一步提升系统智能化水平，本文提出一种改进的N-BEATSx预测算法，在模型结构中引入多尺度残差增强模块(MSRR)和通道–时间注意力模块(CBAM-1D)，并通过ModernTCN优化基函数，以增强特征表达能力与时序建模能力。实验结果表明，改进模型在多项评价指标上均优于传统预测模型及基准模型。研究结果表明，该系统不仅实现了EAST中央控制系统的国产化替代与实时性能优化，也为聚变装置控制系统的自主可控与智能化发展提供了可行路径。

Abstract: To address the issues of non-unified communication protocols, insufficient real-time performance, and heavy reliance on foreign systems in the EAST central control system, this paper designs and implements a HarmonyOS-based EAST central control system. The system architecture and communication framework are upgraded and optimized through containerized deployment of EPICS IOCs and the introduction of a bidirectional WebSocket communication mechanism. To further enhance system intelligence, an improved N-BEATSx forecasting algorithm is proposed. The model incorporates a Multi-Scale Residual Reinforcement (MSRR) module and a Channel-Temporal Attention Module (CBAM-1D), while ModernTCN is employed to optimize the basis functions, thereby strengthening feature representation and temporal modeling capabilities. Experimental results demonstrate that the improved model outperforms conventional forecasting methods and baseline models across multiple evaluation metrics. The findings indicate that the proposed system not only achieves domestic substitution and real-time performance optimization of the EAST central control system but also provides a feasible pathway toward autonomous controllability and intelligent development of fusion device control systems.
