大型结构试验和结构监测中的数据采集系统

DATA ACQUISITION SYSTEM FOR LARGE-SCALE STRUCTURAL EXPERIMENTS AND MONITORING

结构试验和结构监测正在向大型化和复杂化发展,与之配套的数据采集系统也要能满足它们不断增长的需求。清华大学土木工程系开发了适用于土木工程结构试验与监测的集成数据采集系统 IMPDAS,它具有测点多,速度快,功能全等优点。它的任务,不仅仅是记录数据,而是集成并且管理数据,将各种数据信息有条理,有重点地反馈给试验者。本文将讨论计算机在大型结构试验和结构监测的数据采集及数据处理分析等方面的应用。

Structural experiments and real-time monitoring is becoming larger and more complex. Data acquisition system are required to keep up with the expanding demands. Civil Engineering Department of Tsinghua University has developed a data acquisition system-Impdas which is applicable to all kinds of engineering experiments and structure monitoring. This system can deal with a large quantity of measurement points, and high speed is also one of its merits. The system can not only record data automatically, but also integrate and manage the recorded data. It feeds back all necessary information consecutively. In this paper, the computers usage in data acquisition and data management in large-scale structural experiments and monitoring is discussed.
