[0002] Fire extinguishers contain chemicals used to extinguish fires. They are common firefighting equipment and are found in public places or areas where fires may occur. Different types of fire extinguishers contain different ingredients. There are many types of fire extinguishers. They can be divided into portable and cart-type by their method of transport; they can be divided into gas cylinder type, pressure storage type, and chemical reaction type by the power source of the extinguishing agent; and they can be divided into foam, dry powder, halogenated hydrocarbons, carbon dioxide, and water by the extinguishing agent used.

[0003] At present, the management of portable fire extinguishers is carried out through manual regular inspections, which are carried out by fire management personnel alone. The main purpose is to check whether the pressure gauge of the fire extinguisher is leaking. By checking the pressure and temperature values ​​of the fire extinguisher, it is determined whether the fire extinguisher is in normal condition. However, in the period between two inspections, if the fire extinguisher has a leak, it will not be discovered in time, and the leakage rate of the fire extinguisher is relatively fast, which may lead to emergencies, and the fire extinguisher cannot be used, posing a fire safety hazard.

[0004] Therefore, there is an urgent need to provide a portable fire extinguisher monitoring and management system based on Internet of Things technology, which can facilitate timely detection of fire extinguisher leakage and timely replacement of fire extinguishers compared with the existing technology.
