摘要:为应对日益凸显的各类燃气管网安全隐患,确保燃气管网安全运行,本文结合重庆市燃气管网的现状,设计了燃气管网安全隐患监控系统,实现了管网中燃气泄漏自动检测与速报。该系统采用三层B/S体系结构;管理人员可监测管网的运行状态,查询历史数据,及时掌握安全隐患;全天24小时监测,一旦发生事故,迅速通过短信报警,并提供准确的地点和事故状态。现场测试与使用表明,该系统减轻了巡线工劳动强度,缩短了应急响应的时间,提高工作效率。

Abstract: This paper designs a gas network hidden danger monitoring system to achieve the automatic detection and rapid determination of gas network leakage combined with current situation of gas network in Chongqing in order to cope with the increasingly prominent security risks of various types of gas network and ensure the safe operation of it. This system uses three-tier architecture of the B/S mode. The manager can monitor the running state of the pipe network, query the history data and grasp the hidden danger in time. It achieves the full monitoring of 24 hours. Once the accident occurs, it can alarm quickly through short message and provide accurate location and accident status. Spot test and field operation indicate that the labor intensity of line patrol person is greatly reduced, the time of emergency response is shortened and the work efficiency is improved.
Keywords: B/S mode; gas network; automatic detection; short-message alarm
1 概述
燃气管网燃气泄漏时有发生,由此引起的火灾和爆炸事故频发,造成重大伤亡和经济损失,如何加强对燃气管网的安全管理,及时发现并准确定位管网重大隐患,采取有效应急措施消除燃气管网的安全隐患,防止燃气事故的发生,是当前燃气管网安全运行管理的首要问题,也是人们关注的社会问题。
燃气管道一旦发生事故,不仅会带来生活不便和经济损失,严重时还会引起火灾、爆炸等重大恶性事件[1],并造成重大的人员伤亡。早期,人们大多采用人工巡视或者各种基于光学、声学、化学等原理的仪器设备对管壁和管道周围环境进行监测以实现泄漏检测[2]。此种基于硬件的方法检测速度慢,检查时间有限,受到环境等因素的影响较大,容易出现漏检等情况。随着计算机技术的发展和SCADA( Supervisory Control and Data Acquisition)系统在管线上的应用,泄漏检测技术已成为SCADA系统的一个重要组成部分[3]。……
