HT-7 is the first superconducting tokamak device for fusion research in China. Manyexperiments have been done in the machine since 1994, and lots of satisfactory results have beenachieved in the fusion research field on HT-7 tokamak [1]. With the development of fusion re-search, remote control of experiment becomes more and more important to improve experimentalefficiency and expand research results. This paper will describe a RCS (Remote Control System),the combined model of Browser/Server and Client/Server, based on Internet of HT-7 distributeddata acquisition system (HT7DAS). By means of RCS, authorized users all over the world cancontrol and configure HT7DAS remotely. The RCS is designed to improve the flexibility, open-ing, reliability and efficiency of HT7DAS. In the paper, the whole process of design along withimplementation of the system and some key items are discussed in detail. The System has beensuccessfully operated during HT-7 experiment in 2002 campaign period.
