Research on low power control of coal mine roof and floor wireless sensor networks

This paper focuses on the research of low-power consumption control for wireless sensor networks in coal mine roof and floor monitoring. Considering the characteristics of coal mine roof and floor sensors, which require long-term continuous operation and rely on battery power and wireless transmission, low-power design becomes crucial for extending their operational lifespan, reducing battery consumption, and lowering maintenance costs. Therefore, a low-power wireless sensor network for coal mine roof and floor monitoring is designed. This network integrates LoRa wireless transmission technology and WaveMesh network, enabling self-organizing networks, relay transmission, and long-distance data transmission for sensor nodes, effectively meeting the demands of monitoring the roof and floor conditions within coal mine tunnels. By optimizing low-power control strategies, the energy efficiency of the entire sensor network is enhanced, providing reliable technical support for coal mine safety production.
