For communication and energy supply problems caused by sensors wiring in condition monitoring, a novel wireless monitoring system based on Piezoelectric Energy Harvesting (PEH) and Wireless Sensor Network (WSN) were proposed to realize self-powered and intelligent detection of electrical traction shearer. With the maximum power accumulated from kinetic energy, the working condition monitoring sensors and wireless communication module were powered. By analyzing the function of modules, this paper put forward an self- powered WSN monitoring system scheme, introduced the developing of the monitoring system which include the Omni-directional energy collection device structure and optimization its structure and parameter, low power energy harvesting circuit design, modeling of energy collection efficiency, WSN nodes design and its energy consumption analysis. This research helps to solve the difficult in sensor wiring, communication, power supply and contribute to improve the level of condition monitoring for electrical traction shearer.
