The　traditional　smoke　sensing　systems　have　some　disadvantages,　including　high　implementation　costs,　difficulties　in　perceiving　working　states,　low　data　accuracy　and　troubles　in　uniform　and　effective　management.　To　address　these　problems,　a　new　type　of　smart　wireless　fire　monitoring　system　based　on　NB-IoT　technology　is　innovatively　designed,　which　realizes　real-time　remote　monitoring　and　management.　Compared　with　traditional　smoke　alarm　systems,　this　system　has　such　advantages　as　ultra-low　power　dissipation,　lithium-ion　battery　power,　no　wiring,　remote　monitoring,　low　battery　alarm　and　so　forth.　With　great　application　prospect,　it　is　worth　to　develop　and　rolled　out.　©　2020　Published　under　licence　by　IOP　Publishing　Ltd.
