摘　　要：针对目前用于天然气突发泄漏的三维扫描激光气体遥测系统遥测距离短、探测精度低、系统软件功能简单、集成度低、通用性差等问题,设计了一种基于LabVIEW的三维扫描激光气体遥测监测系统。该系统由三维扫描激光气体遥测仪和监测系统软件组成,监测系统软件采用LabVIEW平台进行搭建,应用并行编程技术,构建了视频、云台控制和激光气体遥测等模块,实现了对三维扫描激光气体遥测仪的远程控制和视频、气体浓度等数据的实时采集、显示、分析、存储和历史数据查询。通过实际环境模拟甲烷泄漏气团测试,结果表明系统测量相对误差在±5%范围之内,具有误差允许范围内的一致性,完全可应用于实际燃气管道和燃气场站等场所天然气突发泄漏的实时在线、非接触、远距离和高精度三维扫描遥测。Aiming at the problems of short telemetry distance,low detection accuracy,simple system software function,low integration,and poor versatility of the current 3 D scanning laser gas telemetry system used for sudden natural gas leakage,a LabVIEW-based 3 D scanning laser gas telemetry monitoring system was designed.The system consisted of a three-dimensional scanning laser gas telemeter and monitoring system software.The monitoring system software was built on the LabVIEW platform,and parallel programming technology was used to construct video,pan-tilt control and laser gas telemetry modules,which realized the remote control of the 3 D scanning laser gas telemeter and the real-time collection,display,analysis,storage and historical data query of data such as video and gas concentration.Through the actual environment simulation of methane leakage air mass test,the results show that the relative error of the system measurement is within±5%with consistency within the allowable error range,and the system can be used for real-time online,non-contact,long-distance and high precision 3 D scanning telemetry of sudden natural gas leakage in actual gas pipelines and fuel gas stations.
