EAST Remote Control Portal System Design And Development

With the rapid development of communication technologies and computer soft-ware technologies,computer technology has played an extremely important role in the development and upgrading of large-scale nuclear fusion devices(such as ITER,D?-D,and Alcator C-Mod)worldwide,and also for the world.Nuclear technology experts provided support for remote academic and technical exchanges.EAST,as a large sci-entific device for thermonuclear fusion in China,has developed into an internationally important collaborative experimental platform.The physical characteristics of nuclear fusion experiments determine that thermonuclear fusion devices are not easily accessi-ble.Therefore,we have established a data service system and advanced plasma control system that supports remote participation on EAST,providing analysis data in real time under the support of physical diagnosis and analysis.The Web-based 3D visualization technology realizes the quasi-real-time remote visual display of the discharge process,the setting of key experimental parameters and the verification of commands,the reli-able and secure login of remote experiments,and the secure and rapid data analysis and acquisition.The EAST remote control portal system provides network security for the entire system.Therefore,it is of great significance to develop a safe and efficient portal system.The key technologies of the EAST remote control portal system include digital certificate authentication technology based on OpenSSL,short message cat-based SMS transmission technology,and face recognition technology based on Dlib and OpenCV.The main functions of the system include user security access,experimental data vali-dation,and user back office management.User security access mainly uses IP address restriction,digital certificate verification,user name password,SMS(mailbox)verifi-cation code,random verification code,and face recognition to verify user identity.The user must access the remote control system in a specific laboratory.The user can log in using the user name + password + SMS(email)+ random verification code,or log in using face recognition.Both login methods are convenient for the user to log in.It also ensures the safety of the remote control system.The experimental data valida-tion is to verify data submitted by the user,and the portal system is designed with a front-end and back-end + EAST server three-tier data validation structure to ensure that the user submits data in accordance with the system requirements.The user background management mainly provides the user with viewing historical experiment data and their own authority,and requests the administrator to apply for the service according to the demand.The remote control portal system not only provides security for EAST,but also provides users with a good landing management function,improves the user's use of physical examination,and promotes the development of remote control platforms.The innovations in this article are as follows:(1)OpenSSL-based digital certificate authentication and user login management system is provided to provide user login authentication,data management and data val-idation functions.(2)Establish an autonomous and controllable face recognition platform based on Dlib and OpenCV,and realize the user's face recognition login function.(3)Establish an autonomous and controllable mailbox and SMS delivery platform to provide users with SMS and email verification code delivery services.
