A Key Technology of Centralized and Concurrency Control Test Instrument Used in Large Experiments

摘要:

为了实现Z-pinch研究的大型实验中大数量多种类测试仪器的集中控制,利用虚拟仪器技术和并发控制技术管理数十台测试仪器,介绍了基于delphi和SQL servers数据库的管理控制系统设计,给出了实现控制的核心技术及软件实现代码;结果表明,并发控制技术的应用大大改善了原有的实验控制系统,获取50台仪器数据的时间降到40秒左右;这种基于虚拟仪器的并发控制技术,控制更多数量的测试仪器是可行的,对于从事实验仪器控制的技术人员有很现实的参考意义。

Abstract:

In order to centralized control various test equipment in large Z-pinch experiments, virtual instrument technology and concurrency control method are introduced into the system. And the core technology and the software code based on Delphi and SQL server database are given. Experiments have proved the application of concurrency control technology improves the original experiment control system greatly, for example, the acquisition time of 50 instrument data is reduced to about 40 seconds. This method has also been proved feasible in controlling more test equipment and has realistic reference significance for technicians engaged in experimental instrument control.
