Research on monitoring of gas cylinder microdeformation in metro gas fire extinguishing system
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 acci-dents.Therefore,in order to ensure the safety of fire fighting cyl-inders,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 de-tect the micro-deformation of high-pressure cylinders,and the in-formation can be transmitted to the centralized management of the big data platform by using Ethernet to realize the function of ac-tive supervision.
