【摘要】:為實(shí)現(xiàn)小粒種咖啡種植園的精量灌溉,達(dá)到節(jié)水增收的目的,基于無(wú)線傳感器網(wǎng)絡(luò)(WSNs)設(shè)計(jì)了一種滴灌自動(dòng)控制系統(tǒng),主要由傳感器節(jié)點(diǎn)、簇頭、控制節(jié)點(diǎn)和匯聚節(jié)點(diǎn)組成。測(cè)試了節(jié)點(diǎn)間的有效通信距離為50m,并在此基礎(chǔ)上,采用靜態(tài)簇和節(jié)點(diǎn)定位布置的方法進(jìn)行了灌區(qū)劃分和節(jié)點(diǎn)部署,每個(gè)灌區(qū)為邊長(zhǎng)50m的正方形,內(nèi)設(shè)1個(gè)簇頭、1個(gè)控制節(jié)點(diǎn)和4個(gè)傳感器節(jié)點(diǎn)。采用定時(shí)通信與時(shí)間同步技術(shù)、休眠技術(shù)相結(jié)合的方法實(shí)現(xiàn)節(jié)點(diǎn)數(shù)據(jù)的無(wú)線傳輸,融合土壤含水率、光強(qiáng)和空氣溫濕度等信息,采用分區(qū)輪灌策略實(shí)現(xiàn)滴灌的自動(dòng)控制。實(shí)驗(yàn)結(jié)果表明:系統(tǒng)實(shí)現(xiàn)了預(yù)期設(shè)計(jì)目標(biāo),能應(yīng)用于小?Х葓@的精量灌溉管理。
[Abstract]:In order to realize the precision irrigation of small seed coffee plantation and achieve the purpose of saving water and increasing income, an automatic drip irrigation control system based on wireless sensor network (WSNs) was designed, which consists of sensor node, cluster head, control node and convergent node. The effective communication distance between nodes is 50 m. On the basis of this, the method of static cluster and node location is used to divide the irrigation area and deploy the nodes. Each irrigation area is a square with a side length of 50 m and a cluster head inside. One control node and four sensor nodes. The technology of timing communication and time synchronization is used to realize the wireless transmission of node data, the information of soil moisture content, light intensity and air temperature and humidity is fused, and the automatic control of drip irrigation is realized by the strategy of partition rotation irrigation. The experimental results show that the system has achieved the expected design goal and can be applied to the precision irrigation management of small-grain khakephalic orchards.
