| With the development of science and technology, and scientists of the bold attempt, thefuture of wireless transmission technology to electric power production and delivery two bigproblems with great convenience.For a long time, scientists around the world in order toachieve the wireless transmission of electrical energy made great efforts.From the earliestnikola tesla for wireless transmission of the grand plan, recently, a professor of physics at theMassachusetts institute of technology Marion SuoJia sich wireless bulb experiment,confirmed the scientists.In daily life and production, the radio can transmit the applicationprospect is very broad, its application domain involves the military, medicine, transportation,and daily household electrical appliances, etc.Radio have been able to transport, however, arestill unable to breakthrough the limitation of distance and efficiency, cannot be efficient forpopularization and application.And the research achievements of recent exciting, let peoplemore and more feel the benefits of wireless transmission to the daily life.Resonant can radiotransmission technology is the use of electromagnetic resonance principle and break throughthe traditional use of coupling electromagnetic induction principle and the use of radio wavesprinciple of radio transmission technology, and wireless transmission of electrical energy.First of all, based on the mutual inductance coupling model of the two coil spacedistance, from the perspective of circuit analysis system transmission efficiency and therelationship between the coil size, distance, get the expressions of transfer efficiency, furtherinsight into the factors influencing the wireless transmission technology.And based on thecharacteristic analysis of emission source resonant wireless power transmission system, theresearch on the load power supply when there are multiple source at the same time, theinfluence of equivalent simplification and through the space geometric structure analysis, it isconcluded that multiple source coexistence will increase the complexity of the systemanalysis, and simplified the wireless transmission device greatly reduces the analysis moredifficult.At the same time, the essay focuses on the study of radio can transmit coil model,discusses the best way to realize the wireless transmission coil, in order to realize the resonantradio can transmit system optimization design target.Design made a multidimensional rotarywireless transmission device, by comparison and analysis speed and the number of coilcombination preferential system design and further theoretical analysis of this article.Secondly, in order to verify the accuracy of this topic in the theory, this article alsocreated a prototype to verify this theory analysis, prototype production is the key to optimizecoil way of energy transfer, namely how to implement multidimensional energy transfer through the optimization design of wire coil.So if by the rotation of the power source torealize the energy multidimensional transfer inevitably has certain security hidden danger, andthis article through to the optimal design of wireless transmission trunk line circle, namelythrough the trunk circle with a rotary motor, the trunk will of static energy transfer from thetraditional way to change the way for the dynamic energy transfer, actually it is through thechange in the near field repeating coil magnetic field generated by the form of change, toachieve energy through changing rotating magnetic field of multidimensional transfer effect,can guarantee the safety of the power source and power supply for the more load.Throughexperiments show that resonant radio can transmit if using multiple transmitter coil modelwill increase the system cost and complexity, and this paper puts forward themulti-dimensional rotation rotary dynamic transmission coil has a good theoretical method tosolve the directionality of wireless transmission and multiple load at the same time, theproblem of power supply, and help the popularization and application of wireless powertransmission system.However, we found that in the process of experimental verification trunkturns in dead zones exist in the process of spinning, namely load to receive energy isintermittent, and we found the dead area Angle is very small, in order to solve this problem,after many experiments, we found that by repeating coil design into the cross shape can bevery good to eliminate dead zone, and can reduce the rotation speed, therefore, we putforward the further optimization of coil design.Finally, the main work of this topic research content is summarized, and the subject inthe problems in the design process, this paper puts forward the basic idea of further study. |
