摘要
设备之间的物理连接容易引起许多应用故障。利用电磁感应式无线供电技术,信号和电能采用不同的传输频率,将高频数据信号加载在电能传输信号上,实现信号和电能的无接触传输。在此基础上,对高频注入式信号传输的数学模型进行了讨论,对传输信道进行了计算。最后,通过实验证明了该方法实现能量和信号无接触传输的可能性。
The electromagnetic inductive power transmission system transfers the power contactlessly from the electrical sources to loads via the electromagnetic effect.On the basis of electromagnetic inductive power transmission,information and power adopt different transmission frequency,high-frequency data signal is loaded to power signal,information transmission and power transmission are stimultaneously realized. Simple structure is the advantage of this way and it is easy to realize.on the basis of this way,The mathematical model of high frequency injection information transmission is discussed,transmission channel is calculated.The possibility of this communication method is proved through experiment at last.
