In traditional fire management, some information is managed in the form of paper files. Not only is the data record not comprehensive enough, but also it is difficult to consult and manage because data management is not applied. Tiancheng home safety all-wireless products are combined with the cloud platform, which can fully record and manage all the operation traces of equipment implementation. When the equipment fails, the system will automatically report it to the management party and the maintenance party, and the follow-up inspection and maintenance work will also be recorded in the whole process, so as to change the fire control work mode and further improve the fire control work management efficiency.
