    摘要:

    為實(shí)現(xiàn)茶樹需水信息準(zhǔn)確檢測和茶園精量灌溉自動控制，設(shè)計了一套基于無線傳感器網(wǎng)絡(luò)的茶園分布式灌溉控制系統(tǒng)，給出了系統(tǒng)體系結(jié)構(gòu)及軟,、硬件實(shí)現(xiàn)方法,；針對無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)在茶園內(nèi)高度分散的特點(diǎn)，提出兩種適用于不同規(guī)模茶園的分布式灌溉控制方案,，設(shè)計了由模糊控制器和最優(yōu)化控制器組成的分層灌溉控制器，使得系統(tǒng)可在滿足一定性能指標(biāo)前提下，實(shí)現(xiàn)茶園精量灌溉控制,。試驗(yàn)結(jié)果表明系統(tǒng)設(shè)計合理可行，特別適用于大型農(nóng)田,、果園,、苗圃等區(qū)域的精量灌溉。

    Abstract:

    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.
