Fire extinguisher management system

The invention relates to a fire extinguisher management system, which is characterized by comprising fire extinguisher assemblies, building numerical control assemblies and a master control system. Each fire extinguisher assembly is directly connected with a pressure gauge port of a fire extinguisher and is used for judging whether the fire extinguisher is in voltage shortage or not and collectingex-factory cure address information; the building numerical control assemblies are connected with the various fire extinguisher assemblies; the master control system is connected with the various building numerical control assemblies; the building numerical control assemblies supply power to the fire extinguisher assemblies through power cables, collect the voltage shortage information and the address information of the fire extinguisher assemblies through wired communication circuits, and transmit the information to the master control system through optical fibers converted from RS485; the master control system rece
