Design of mine environmental data acquisition equipment based on wireless ad hoc networks

For status that most coal mine safety monitoring and control systems adopt fixed and wired sensor network which has blind spots, the paper proposed a design scheme of mine environmental data acquisition equipment based on wireless ad hoc networks, and introduced design of low-power wireless ad hoc networks in details. The equipment takes ATmega16L signle-chip microcomputer as master chip, achieves wireless transceiver by RF transceiver chip NRF24L01, and uses planar network topology and on-demand routing mode. It realizes collection of mine environmental data and early warning, reduces monitoring blind spots, and has higher security and reliability.
