The system comprises an ARM microcontroller, an NB-IoT wireless transmission module, asound-light alarm module and a smoke sensor. The ARM microcontroller is in communication with the NB-IOT wireless communication module through a UART interface. The ARM microcontroller collects signal output of the smoke sensor through an AD interface. The ARM microcontroller is provided with an I/O interface. The sound-light alarm module is controlled by the I/O interface to carry out sound andlight alarm. Wherein the ARM microcontroller, the NB-IoT wireless transmission module, the sound-light alarm module and the smoke sensor provide electric energy through a battery, the ARM microcontroller is provided with an AD interface, and the energy state of the battery is read through the AD interface. The beneficial effects of the utility model are that the system is high in monitoring speed,is high in signal quality, and is high in reliability, portability, stability and safety.
