Abstract: This paper described and compared the main monitoring technologies and devices of firefighters' respiratory rate, designed a set of respiratory rate monitoring device for firefighters training based on micro pressure sensor, and studied the device selection, and system construction of the device. The device adopted the half-face mask type, which can collect the respiratory rate of firefighters during training in real time, and can fuse with the data collected by other firefighters' vital signs equipment, transmit it to the firemen's body area network sink node through Bluetooth, and then transmit it to the big data cloud platform through the network. Through long-term tracking the respiratory rate data collected by the device, it is of great significance to evaluate the training effect of firefighters, improve the respiratory efficiency and enhance the combat effectiveness of fire rescue team.

Key words: fire fighting training, firefighter, micro-pressure sensor, respiratory rate
