摘　　要：目前,国内外有多种燃气管道泄漏检测方法。本文结合我国管道的现状,借鉴国际检测方法和计算机自动化仪表的实践经验,研究了长输天然气管道泄漏实时监测模型。基于无线技术的数据采集方案在结构监测、交通运输和环境研究等领域得到了广泛的应用。本文介绍了一种基于GPRS的远程数据采集与预报系统,该系统用于监测地下天然气管道沿线的地质灾害。现场数据终端单元(DTU)从安装在管道上的传感器采集数据,并通过GPRS模块将数据传输到控制中心的服务器,服务器处理数据在网站上播放并及时预测异常变化。At present,there are many gas pipeline leakage detection methods at home and abroad.In this paper,combined with the current situation of China's pipelines,and the practical experience of international detection methods and computer automation instruments,the real-time monitoring model of long-distance natural gas pipeline leakage is studied.Data acquisition scheme based on wireless technology has been widely used in structure monitoring,transportation and environmental research.This paper introduces a remote data acquisition and prediction system based on GPRS,which is used to monitor the geological disasters along the underground natural gas pipeline.The field data terminal unit(DTU)collects data from the sensors installed on the pipeline,and transmits the data to the server of the control center through GPRS module.The server processes the data,plays it on the website,and predicts the abnormal changes in time.
