摘要:
分析感应耦合原理并制作耦合器,将仿真与实测相结合,在高频变压器模型基础上建立单个耦合器的准确电路模型。然后对多节耦合器连接的电路特性进行分析,得到每增加一个耦合器就增加了一个谐振回路的规律,进而得到磁感应传输信道的电路模型。针对多级信号传输的衰减问题,采用电容补偿的方法,增加谐振频率点的幅值以提高信号传输效率。最后,建立用于随钻信息磁感应传输的实验系统,验证磁感应信道电路模型的有效性。选取模型中的两个谐振点作为通信频点,在20节的传输系统中实现了115.2kbit/s的通信速率。

Abstract:
Based on a high frequency transformer model, an accurate circuit model of inductive coupler was established by combining theoretical analysis on the magnetic inductive coupling principle and coupler simulations. The analysis results of the characteristics of multiple couplers connection show that adding a coupler would result in increase of a resonant circuit, therefore a circuit model of the magnetic inductive transmission channel was obtained. To solve the problem of attenuation in the multisection signal transmission, capacitance compensation was adopted to increase the amplitude of the resonant frequency, thus to improve the efficiency of the signal transmission. To verify the circuit model of the magnetic induction channel, an experiment of the data transmission with drilling was carried out. By selecting two resonance frequencies in the model as communication frequency, a 115.2kbit/s communication rate in section 20of the transmission system is achieved.
