The practical experiments of the designed intelligent two - wire valve present a good preferment . we model the power - line channel in chapter 4 as the experimental result shows that the power - line channel condition has civilizing influence upon the valve ' s communication performance . here , we establish power - line resistance model base on theory of transmission line 在实验中我们发现电力线信道特性的变化对智能二线阀系统的性能有着比较明显的影响,从研究的系统性出发,同时,也是作为从物理实践到理论研究的一个重要步骤,我们在第四章中对电力线信道建模和电力线载波通讯进行了仿真研究。
