Abstract: According to the experimental request of HT-7 superconducting Tokamak, the temperature of limiter surface must be showed on monitor and fast gathered. The implementation method and anti-interference measure of this faint signal acquisition system are introduced. An effective and flexible scheme based on VB6.0, configuration software, DDE (Dynamic Data Exchange) and ODBC (Open Database Connectivity) technology is described mainly. It can meet the demands of data high frequency record, saving automatically by number and fast inquiry.
