摘　　要：为帮助学生更好地理解和掌握无线地下传感网信道传播特性,推导并建立一个融合土壤特性参数的改进地下无线信道传播模型,在该模型基础上开发无线地下传感网实验虚拟仿真系统。该仿真系统不仅解决实验环境受限、难以开展实验教学的问题,且具有易于理解和操作的特点,仿真结果以图形化和可视化的形式呈现。通过此系统,学生可直观地观察和比较不同参数影响下地下无线信道传播变化情况,深入理解地下无线信道的复杂传播特性,提高学生的学习效率,激发学生的学习兴趣,促进学生学习的主动性和积极性。In order to help students better understand and master the channel propagation characteristics of wireless underground sensor networks(WUSN),this paper derives and establishes an improved underground wireless channel propagation model that incorporates soil property parameters.Based on this model,a virtual simulation experiment system for WUSN is developed.This virtual simulation system not only solves the problem of limited experimental environment and difficulty in conducting experimental teaching but also has the advantages of easy understanding and operation,with calculation results presented in a graphical and visual format.Through this system,students can intuitively observe and compare the changes in underground wireless channel propagation under the influence of different parameters,thereby gaining an in-depth understanding of the complex propagation characteristics of underground wireless channels.This not only enhances the students’learning efficiency but also effectively stimulates their interest in learning,fostering proactivity and enthusiasm in their studies.
