The Structure of The Experiment Ethernet is a compound of star structure and multilayer structure. all the fast applications are directly connected to the center switch in star style, and others are connected to lower level switches in multilayer style. The Experiment Ethernet reaches all places of HL-2A experiment The nodes connected in the Experiment Ethernet are more than 400 computers in total The implemented security measures include dividing the network into different sections with routers and multi Ethernet adapters inserted in servers protecting the network from attacked with hardware firewalls mending OS and updating the virus data online automatically powering center switches and the key servers by UPS using optic cables as the interconnecting medium between different places Assigning authority to users for executing the permitted functions,HL-2A Experiment Network,www.swip.ac.cn,The Center of HL-2A Exp. Network,www.swip.ac.cn,HL-2A Experiment Data Acquisition,3 types of data are acquired, they are pulse signal dataprocess signal dataimage signal data There are 50 sub-systems with 1200 channels in total. The highest ADC rate is 60 MW/S The maximum quantity of data acquired per one shot is 600 MB. The data acquisition system is distributed in both logic and physics.,www.swip.ac.cn,Data Acquisition sub-systems,HL-2A Experiment Data Processing,Other data,Files,database,Thin clients,Fat clients,Three Layer structure,HL-2A Experiment Data Processing,The Data Processing is Applied toreal time data processing for display & controlinteracting data processing for commonly analysispost data processing for professional analysis Transaction servers are used to supply the pre-processed data The Functions of Data pre-processing include arithmetic, mathematic calculation, professional analysis and digital signal processing, multi channels can be included in one processing, personal processing and multiprocessing can be defined by user selves. 3 versions of processing software are developed, two of them are server/client structure the third is an application based on file sharing They have been installed in more 300 PC,Digital Signal Processing,The Client Based on windows,Inquiring & figures display,Set Personal Configuration,The Client Based on WEB,Analysis App. Based on Files Sharing,The Center Hall of HL-2A Experiment,HL-2A Display System,The display system is constructed by a big screen in the center hall some screens located other places a lot of processing sub-systems several related servers HL-2A big screen consists of24 50-inch display units and their accompanying adaptersa 120 inch display unit and its accompanying adaptermutli. image capture cards20 color CCD cameras 10 pan & tilt heads and the corresponding controllers a LED screen with a dimension of 50cm high and 600cm wide several IPC The functions of the system include display the purpose description of the current experiment, welcome statements and some parameters visualizing some measured signal display the preset control curves & the actual result curves showing plasma images, video, analyzed graphs and so on.,HL-2A Dada Storage System,It is a multilevel storage constructed by: data acquisition computers online data servers backup data servers tape library with 8 LTO2 drivers The data tapes placed far from the online data servers It is powered by UPS Support data access in 24 hour per day Both the current data and the history data are online A backup system is built to save: all kinds of files SQL server and MY SQL database Windows server OS & Linux server OS system data The backup is Managed by VERITASTM BackupExec10.0 Data access & management are supported by a series of applications developed by ourselves,The Storage System Structure,Firewall,Center switch,WAN,、,EMAIL server,Control PC group,Router,Control server,WWW server,Tape library,System backup,incremental backup,Center switch,Acquisition PC group,Processing PC group,
