摘要 为实现茶树需水信息准确检测和茶园精量灌溉自动控制,设计了一套基于无线传感器网络的茶园分布式灌溉控制系统,给出了系统体系结构及软、硬件实现方法;针对无线传感器网络节点在茶园内高度分散的特点,提出两种适用于不同规模茶园的分布式灌溉控制方案,设计了由模糊控制器和最优化控制器组成的分层灌溉控制器,使得系统可在满足一定性能指标前提下,实现茶园精量灌溉控制。试验结果表明系统设计合理可行,特别适用于大型农田、果园、苗圃等区域的精量灌溉。 In order to acquire tea plant water requirement precisely and achieve tea plantation precision irrigation control, the distributed precision irrigation control system based on wireless sensor network for tea plantation was developed, and the system architecture, hardware configuration and software design approach were also introduced in detail. According to the characteristics of many wireless sensor network nodes highly dispersed in tea plantation, two kinds of distributed irrigation control methods applied to different scale tea plantations were proposed, and the hierarchical irrigation controller composed of fuzzy controller in the lower layer and optimal controller in the upper layer was designed. The developed system with distributed hierarchical irrigation controller can realize tea plantation precision irrigation control and satisfy the certain irrigation performance index. Preliminary experimentations indicated the rationality and practicability of the system. It can be effectively applied to the large scale precision irrigation areas, such as the cropland, the orchard and the nursery garden, etc.
