【摘要】：天然气由于其污染性低,环保等特性被越来越多的使用在社会生活的方方面面。但天然气的主要运输途径是管道,管道的泄露监测及管理即成为天然气运输过程中保障安全性的重要因素。城市地下燃气管网位于复杂多变的地下环境中,具有压力低,多分支,多附件等特点,导致泄漏监测管理的难度很大,地下燃气管道的泄漏监测是急待解决的问题之一。本论文基于浓度传感器网络设计实现了管网泄漏实时监测管理系统,该系统利用浓度传感器实时采集管网天然气浓度并回传给控制端进行数据的存储、分析及告警处理,以实现对天然气管网泄露的实时监测及管理功能。论文研究的主要内容包括管网拓扑模型的研究、提出传感器的布局策略并实现了浓度传感器的管网布局、实时采集及传输浓度数据、设计并实现了控制端系统。控制端系统利用Access数据库进行数据的后端存储、在MyEclipse环境中开发前台系统对采集的数据进行实时分析以便发现异常并以告警的形式通知管理者,达到对天然气管网泄露的实时监测和管理的目的。通过测试,本系统能够完成对地下燃气管道泄漏的实时监测和管理,系统在安全性、实用性、功能性及成本方面均可以满足现有天然气环境的需求。
[Abstract]:Natural gas is more and more used in all aspects of social life because of its low pollution and environmental protection characteristics. But the main way to transport natural gas is through pipelines. Pipeline leakage monitoring and management is an important factor to ensure safety in the process of natural gas transportation. Urban underground gas pipeline network is located in a complex and changeable underground environment, with the characteristics of low pressure, multiple branches, multiple accessories, etc. The leakage monitoring of underground gas pipeline is one of the urgent problems to be solved. Based on the concentration sensor network, the real-time monitoring and management system of pipeline leakage is designed and implemented in this paper. The system uses the concentration sensor to collect the natural gas concentration of the pipe network in real time and sends it back to the control end for data storage, analysis and alarm processing. In order to realize the function of real-time monitoring and management of natural gas pipeline leakage, the main contents of this paper include the research of network topology model, the layout strategy of sensor and the distribution of concentration sensor. The control system is designed and implemented. The control system uses Access database to store the data at the back end. In the environment of MyEclipse, the foreground system is developed to analyze the collected data in real time in order to find the anomaly and notify the manager in the form of alarm, so as to achieve the purpose of real-time monitoring and management of the leakage of natural gas pipeline network. The system can realize the real-time monitoring and management of underground gas pipeline leakage. The system can meet the needs of the existing natural gas environment in terms of safety, practicability, functionality and cost.
