Realization of Dynamic Information Data Transmission Function of Fire Scene Based on NB-iot

At present, the development of real-time information collection technology in the field of fire protection is relatively lagging behind, which affects the further improvement of rescue efficiency. In this paper, the information collection technology integrated in the intelligent helmet is taken as the research object to solve the problems such as the low level of monitoring in the field of fire protection and the existence of monitoring blind area. The smart helmet takes STM32 main controller as the core, uses nb-iot technology to transmit the collected environmental information wirelessly, and sends the collected information to the client through at command, which provides the basis for the backstage commanders to formulate the rescue strategy and improves the rescue efficiency.
