摘要
当采用多台分布式光纤测温主机对混凝土坝多坝段进行实时在线温度监测时,若人工提取测温主机的监测数据,势必削弱分布式光纤测温主机在线测温和实时监测的优势。对多坝段、多台分布式光纤测温主机远程控制系统进行了研究,结合建设中的溪洛渡特高拱坝,采用VB开发平台上的Winsock和Timer控件,将3台测温主机与服务器连接起来构成小型局域网,初步实现了分布式光纤测温远程控制。工程实践表明,该系统可以满足在测温过程中数据的实时采集及监控,为混凝土坝温度的光纤实时在线监测提供了有利的技术保证。
When real-time online temperature monitoring for dam sections by the distributed temperature sensing(DTS) host is conducted,manual acquisition for the temperature monitoring data of the host inevitably limits the real-time,online monitoring advantages of distributed optical fiber temperature measurement host.We devote to establishing a remote control system for the multi-dam and DTS host,by the Winsock and Timer control of VB development platform,3 temperature sensing hosts are linked with a server to form a small-scale Lan,preliminarily realizing the remote control of distributed optical fiber temperature measurement.The practice shows that the established system can meet the requirements of real time data acquisition and monitoring,providing a favorable technical assurance for the real-time online temperature monitoring of concrete dams by optical fiber.
