Meteorological data has the characteristics of rapid change and large data volume.In com-plex communication environments,data loss or errors are prone to occur.In order to improve the quality and speed of Meteorological data transmission,NB-IoT technology is used to optimize a meteorological data transmission control system.Modify the meteorological data collector and transmission controller,add a narrowband IoT module,and achieve hardware system optimization.The NB-IoT technology is used to collect meteorological transmission data,and the meteorological data transmission channel is se-lected with comprehensive consideration of meteorological data transmission volume,channell capacity and other factors.Finally,the transmission control function of meteorological data is realized from two as-pects:transmission security and transmission speed.Through of the optimized design system,the loss rate and the bit error rate of the transmitted meteorological data are reduced by about 2.63％and 0.96％respectively,and the transmission delay of meteorological data is effectively shortened.
