摘要: 市场上使用的部分消防气瓶已远超年限,存在潜在的安全隐患,容易发生气瓶爆炸事故。因此,为保障消防气瓶安全,研究开发了以检测消防气瓶微变形为基础的安全监测技术,采取在气瓶表面缠绕线型传感器的方法检测变形。通过气瓶爆破试验,验证了该技术可有效探测高压气瓶的微变形,并利用以太网将信息传输至大数据平台集中管理,实现主动监管功能。

Abstract: Some of the fire extinguishing gas cylinders available on the market have far exceeded the age limit, there are potential safety hazards and is easy to cause gas cylinder explosion accidents. Therefore, in order to ensure the safety of fire fighting cylinders, this paper develops the safe monitoring technology based on detecting the micro-deformation of such cylinders, which adopts the method of detecting the deformation by winding wire sensors on the surface of the cylinders. Through the cylinder bursting test, it is verified that the technology can effectively detect the micro-deformation of high-pressure cylinders, and the information can be transmitted to the centralized management of the big data platform by using Ethernet to realize the function of active supervision.

Key words: fire extinguishing high pressure gas cylinder, micro-deformation monitoring, wire sensor, cylinder bursting, temperature compensation
