An on-line monitoring system for displacement and leakage was designed for the ex-pansion joints of the hot blast furnace piping system of a steel plant.The sensor adopts NB-IoT wire-less transmission to connect with the monitoring platform,there is no need for on-site wiring and ex-ternal power supply,which is easy to install.Special heat dissipation design is adopted for wireless sensors working under high temperature conditions,and the heat dissipation performance is verified by Fluent simulation.Finally,the whole system is operated on site,realizing the online monitoring of expansion joints in the pipeline system of hot blast furnace,which can be used as a reference for the design of wireless monitoring program for the same type of high-temperature expansion joints.
