Construction of Open-pit Mine Environmental Monitoring System Based on Wireless Sensor Network

Abstract

Green mining in mines should be combined with the emerging new technologies and methods to collect, store and display mine environmental data, so as to achieve the balance between mine economic benefits and environmental protection. In this paper, low power sensor nodes are deployed on a large scale in mines, which is based on LoRaWAN protocol wireless sensor network to build mine environment monitoring system of internet of things. Energy collection, energy management and storage of monitoring nodes are designed to realize self-sufficiency of power supply of monitoring nodes. The single chip microcomputer of the monitoring node reads the sensor data and sends it to the gateway and server, and then the client application program realizes data storage and display of mine monitoring node position, rainfall, PM2.5, temperature and humidity in two dimensions of time and space.
