Research On Energy Wireless Collector Converter Technology Based On Magnetic-field Energy

Wireless sensor network(WSN)is a network system formed by communication between multiple sensor nodes deployed in the monitoring area.But under the condition of current technology,sensor nodes can only rely on battery power supply,this means that when unable to provide the energy and life will run out of sensor network to stop work.Therefore,how to extend the working time of wireless sensor network is a long-term hotspot and difficulty in the research field.And in a variety of wireless set to technology,based on the space of the magnetic energy can set technology for wireless sensor network applications and the development of smart grid has a great role in promoting,has a broad application prospect in the future.In smart power grid,especially in high voltage substations,the magnetic field is abundant.To magnetic energy into electricity power supply for wireless sensor,this paper established a cylindrical surround type mathematical analysis model of magnetic energy converter topology,and from the skeleton skeleton magnetic materials,magnetic structure parameters and can set the coil number of turns three aspects to optimize its numerical induction electromotive force,so as to get around cylindrical type magnetic energy converter design principle and simulation verification,the results verify the good performance of magnetic energy converter.An improved the ball around the type of magnetic energy converter,studied the size of the radius of its inside and outside can effect change on the set,compared the two kinds of round type magnetic energy converter set can ability,verify the efficiency of spherical model,and optimize the structure of works best when the conditions are given,finally through the simulation verify the validity of the theory.Considering magnetic source can not through the converter internal in the actual situation,proposed the separate magnetic energy converter topology,separate magnetic energy converter in the mathematical analysis model is established,and can from set coil number of turns,skeleton material relative permeability,the space magnetic induction intensity and core skeleton structure and so on four aspects to set energy converters of induction electromotive force optimization analysis,the final simulation results have guiding significance to practical application.In order to solve the problem of low energy conversion efficiency and unstable output voltage in the conventional intelligent power grid,the wireless power collecting device is used to adjust the unit energy conversion efficiency.Designed a set can accelerate nursing unit and the flyback type circuit voltage control unit,the energy conversion efficiency and voltage stability has significantly increased,to ensure the stability of the wireless sensor work,performance is superior to the traditional modulation circuit,more suitable for smart grid can use wireless set device of energy conversion and utilization,to set energy converters in played a significant role in the application and development of smart grid.
