摘要
为进一步提高大面积灌溉系统的作业效率与灌溉后田间土壤效果,基于通信耦合理念针对系统展开设计。以大面积灌溉系统控制组成与作业机理为基础,根据灌溉流量与时间的内在关系,考虑信息冗余及检测攻击等条件,应用CI核心耦合算法,结合MatLab最优解,建立大面积灌溉控制的通信耦合理论计算模型,进行系统通信耦合硬件布置架构与软件布局,并实施灌溉作业试验。结果表明:在同一灌溉速率的试验条件下,灌溉前土壤湿度与灌溉时间呈负相关,符合实际;基于通信耦合后的通信数据丢包率在3.51%以下,灌溉均匀度在85.9%~90.3%之间,灌溉后土壤湿度达标率达到95.5%以上。系统可为类似智能控制农机通信改善提供思路与参考,具有较好的推广价值。
In order to further improve the operation efficiency of large-area irrigation system and the field soil effect after irrigation, the system was designed based on the concept of communication coupling. Based on the control composition and operation mechanism of the large-area irrigation system, considering the internal relationship between irrigation flow and time, information redundancy and detection attack, and using CI core coupling algorithm, combined with MATLAB optimal solution, a reasonable calculation model of communication coupling for large-area irrigation control was established, then system communication coupling hardware layout architecture and software layout were designed and irrigation operation test was carried out. The results showed that: under the same irrigation rate, the soil moisture before irrigation was negatively correlated with the irrigation time, which was in accordance with the logic reality;the communication data packet loss rate after communication coupling was below 3.51%, the irrigation uniformity was between 85.9%-90.3%, and the soil moisture standard rate after irrigation was above 95.5%, which would be provide ideas and reference for the communication improvement of similar intelligent control agricultural machinery preparation, and have better promotion value.
