分布式光纤温度传感虚拟仪器设计

分布式光纤温度传感采用拉曼散射原理,对多点多次测量累加消噪,获得测量区温度分布。本文基于虚拟仪器的设计将复杂的测试部件置于标准计算机内,通过操作系统、数据库和LabVIEW完成软件设计,实现了测量数据处理、存储管理和实时监控等功能。虚拟仪器技术充分利用计算机资源,加快了系统开发速度,提高了数据处理能力,便于测试系统应用和维护,适应实际分布式测量和监控环境的要求。

Virtual instrument design of distributed fiber optictemperature sensing

The distributed fiber optic sensing based on Laman scatter,which measures many spots for a lot of times and adds the measure data to achieve the temperature distributing values. Base on virtual instrument technique, a lot of complex measure components are put into a normal computer, using operation system, data base and LabVIEW to design application software, implement measure data processing, data memory manage and real time monitor in measurement, etc. virtual instrument technique can take full advantage of the computer capability, speed up the system design and enhance the capability of data processing.Otherwise, the measurement system is very convenience in functions modification and in a practical temperature measurement; fit the demand for an actual distributed fiber optic sensing and the monitor.
