Multi-parameter monitoring system for coal mine based on wireless sensor network technology

According to the characteristics of coal mine environment, in this paper we propose a multi-parameter wireless sensor network monitoring system based on Zigbee technology for coal mine tunnel. The system can real-time monitor the underground environment and production parameters and intelligently give early warning by using a variety of sensors and wireless sensor network. It is flexible to add sensors and enhance stability of monitoring computer software through RS-485 communication protocol and hardware modular. Experiments have proved feasibility and good stability of the system.
