基于物联网技术的露天矿工艺设备二氧化碳排放监测系统设计与验证OA

In order to monitor the concentration of carbon dioxide(CO2)emitted by open-pit mine process equipment in real time,a CO2 emission monitoring system for open-pit mine process equipment is designed by using the Internet of things technology of wireless transmission of Wi-Fi module,NDIR diffusion CO2 sensor and puzhong STM32F103ZET6 chip microcomputer.It has the functions of real-time monitoring of CO2 concentration,effective storage,multi-channel display,sound and light alarm and wireless transmission.The system is applied to the monito-ring of CO2 concentration emitted by perforation equipment in an open-pit mine.The results show that the monitoring system can monitor the CO2 concentration emitted by KQ-100 drilling rig in real time under complex open-pit mining conditions,and effectively store and transmit CO2 concentration data.When the CO2 concentration is higher than the preset threshold,the sound and light alarm module is triggered,the buzzer alarms,and the LED red light flashes;the packet loss rate of the system is 0,and the CO2 concentration monitoring data on the cloud platform is relatively delayed by 3 s.The monitoring system has the advantages of good stability,high reliability,low power consumption,low packet loss rate and short delay time,which can provide technical support for the optimization of open-pit mining process equipment and carbon emission accounting.
