针对HT-7超导托卡马克实验的具体要求,对与等离子体直接接触的限制器表面温度实现了快速监测与存储。介绍了该微弱信号采集系统的具体实现方法与抗干扰措施。重点论述了一种基于VB6.0、组态软件、DDE(动态数据交换)及ODBC(开放数据库联接)技术的有效、灵活的采集方案,实现了实验数据的高频记录、按次自动存储和快速查询。 关键词:HT-7限制器;数据采集;ODBC;组态软件;DDE 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. Keywords: HT-7 limiter; data acquisition; ODBC; configuration software; DDE
