Abstract: The Wireless sensor network and self-powered technology-based monitoring system was proposed to solve the several problems, such as the poor timeliness of coal machinery equipment condition monitoring system, the difficulty in laying communication cables, and the demand to replace batteries regularly. The system consists of energy harvesting unit, wireless sensor network unit and monitoring software unit; the energy harvesting unit can harvest the mechanical energy of vibration to supply power for the node circuit; the wireless sensor network unit and monitoring software unit realize the collection, transmission and processing of critical state information of equipment. The system can realize the real-time monitoring of machine equipment operating status within 30 m effective range and the maximum output power of energy harvesting unit can reach up to 378 mW, which can effectively collect equipment vibration energy and realize system energy self-supply.

Key words: coal machine equipment, self-powered technology, wireless sensor network, monitoring system
