J-TEXT远程参与实验系统的设计与实现

摘要

An open platform for users to participate in J-TEXT tokamak experiment via Internet remotely was designed .The implementation of Web service applies the Representational State Transfer (RESTful) software architecture, developers can use the open API to develop tokamak applications based on their requirements. Authentication and Authorization system protects the open API against hacker attacks. Implementation of J-TEXT tokamak remote participation system based on ASP.NET Web API framework. In the real time data updating area it uses ASP.NET SignalR library to implement multiple server push strategies. The system is flexible and compatible with Experimental Physics and Industrial Control System (EPICS) software. Now it has been already integrated into the J-TEXT Control, Data Access and Communication (CODAC) system. The test and application results show that the system can work continuously and stably, and meet the requirements of tokamak remote participation.%设计了一个开放平台使研究者能够远程参与J-TEXT装置实验，应用Representational State Transfer (RESTful)软件架构模式实现Web应用，提供大量的开放API给开发者开发托卡马克应用软件。认证和授权功能避免了开放的API被用户恶意使用。J-TEXT装置远程参与实验Web应用使用了ASP.NET SignalR框架，在实时刷新界面状态方面取得良好的效果，还实现了多种服务器推送信息的策略。系统具有良好的灵活性，兼容Experimental Physics and Industrial Control System (EPICS)软件，目前已经集成到J-TEXT Control, Data Access and Communication (CODAC)系统中使用。Web应用和Android应用的测试和使用结果表明，系统能够连续稳定运行，可以满足装置远程参与实验的需求。
