• 3 Ethernet LAN are used– data acquiring and monitoring– HL-2A experiment controlling– data processing and data analysis

• 1 AV (audio & video) network is used for video supervising.• 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 Data Acquisition

• 3 types of data are acquired, they are – pulse signal data– process signal data– image 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.

HL-2A Experiment Data Processing

• The Data Processing is Applied to– real time data processing for display & control– interacting data processing for commonly analysis– post 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

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 of– 24 50-inch display units and their accompanying adapters– a 120 inch display unit and its accompanying adapter– mutli. image capture cards– 20 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 an

d 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
