In order to solve the problem of environmental monitoring and fire extinguishing, this paper proposes a cooperative mode of the master control system and the control implementation system, which can collect, transmit and extinguish the data in the environment where the fire occurs. Using STC15F2K60S2 microprocessor and STM32F103C8T6 microprocessor as the main control system and control the implementation of the system control core, using Multi-sensor, amplifying circuit, wheel motor drive module, GSM and Bluetooth wireless communication module for data processing, temperature, smoke, flame and the human body detection, machine car perform obstacle avoidance logic of fire to track, and other functions. The experimental results show that the system can effectively monitor the environmental data and alarm when the threshold value is exceeded, and analyze and deal with the current environmental conditions. Realize the car search fire source and water function, to achieve the desired effect.
