Outline Current solution for J-TEXT data acquisition, archive and accesssystem The CFET software system framework based on .NET and Web Data acquisition system Data archive and access system User interface and Data Visualization Future work1/18IFPP CEEE HUST Yuxing Wang

Main issue of current solution So many DAQ programs, similar but incompatible, almost nosoftware architecture Need installing MDSplus or other software to see the experimentdata New demands are increasing, and unhappy to modify theexisting system3/18IFPP CEEE HUST Yuxing Wang
CFET Software system framework Control system Framework for Experimental Devices Toolkit Thing is something with its owncontrol logic and Resources A CFET Host is a program which containssome CFET Things. A Thing’s Resources can be accessedthrough the Web by URls, and Thingscontact each others by their Resources.4/18IFPP CEEE HUST Yuxing Wang
Unified Data Access (UDA)All resources in CFET system can be accessed by an URL through theWeb like ecei group1 ch1?start 0&stride 100&count 1000&block 1ConfigDAQ Thing 15/18MethodEventCFETHostCFETHostData ManageThingIFPP CEEE HUST Yuxing WangStatusData Server Thing

New DAQ and Data Access system A flexible architecture to facilitate the addition of new featuresand later modifications Acquisition systems should not rely on specific hardware Data storage and archive systems should not depend on aparticular database or file format but have supports for them likeHDF5 Data access should meet all existing needs7/18IFPP CEEE HUST Yuxing Wang
