Design of underground environmental monitoring and intelligent ventilation system in uranium mine based on ARDUINO

Aiming at the distribution characteristics of the concentrations of radon and radon progeny in the underground confined space of uranium mine,the hazardous mechanism of the operating environment containing radon on the human body in the confined space was analyzed,and an intelligent ventilation and radon reduction of uranium mine based on the “human-machine-environment” interconnection and self-adaptation was proposed.A radon monitoring and intelligent control system based on ARDUINO was constructed,and the “hardware” and “software” solutions of the system were designed.The core hardware of the system were the ARDUINO development board and the ESP8266-WiFi module.The dynamic data of the concentration of dust,the concentrations of radon and its progeny,and the wind speed in the uranium mine were acquired by the corresponding sensors,and they were transmitted to the ARDUINO master control through the sensor data collectors with the corresponding communication protocols,then the ARDUINO main control output the commands to the ventilation equipments and alarm devices.At the same time,the system built a network cloud platform to realize the remote monitoring of environmental monitoring and remote control of intelligent ventilation system.The system can obtain environmental data based on IoT perception,perform intelligent control logic operations,and realize adaptive control and response of ventilation equipment,thereby safely,efficiently,stably,and low-costly regulating the air quality index of uranium mines.
