基于Qt的负离子源中性束注入控制与监测系统设计与实现
Design and implementation of Qt-based neutral beam injection control and monitoring system for negative ion sources
摘要
Abstract
[Background]Neutral beam injection(NBI)systems are critical to fusion research and require precise control and monitoring of negative ion sources.Existing solutions often have limitations in terms of development efficiency and adaptability.[Purpose]This study aims to design and implement a cost-effective,highly scalable NBI control and monitoring system for negative ion sources.The system is specifically designed to address the inherent issues of traditional NI-PXIe hardware and LabVIEW-FPGA architectures,such as lengthy development cycles,high hardware costs,and limited scalability.[Methods]A modular control solution is proposed,utilizing a domestically produced PXIe platform,a Linux real-time system,and the Qt5.9 framework.By replacing imported components with locally sourced hardware and leveraging optimizations in the Linux real-time kernel,precise control is achieved.A multi-threaded control program is developed using C++object-oriented programming to enhance system flexibility and overcome scalability limitations.[Results]Experimental verification confirmed that the system achieved microsecond-level synchronisation accuracy.Compared with traditional methods,this solution has significant advantages in scalability and control accuracy,meeting all experimental requirements for time-sensitive operations in negative ion source NBI.[Conclusions]The Qt-based system successfully addresses the limitations of traditional NBI control architectures in terms of cost and scalability.By adopting localized hardware,Linux real-time system,and modular C++design,the system provides reliable performance for complex ion source experiments.This approach establishes a flexible framework that can adapt to further enhancements in future NBI systems.关键词
