    摘要:

    針對(duì)傳統(tǒng)山地果園灌溉中缺乏智能控制而費(fèi)時(shí),、費(fèi)力等缺點(diǎn),，為提高水資源利用率,，設(shè)計(jì)了基于土壤墑情的自動(dòng)灌溉控制系統(tǒng),，系統(tǒng)主要核心部件包括S3C2440芯片與CC2530射頻芯片,。該系統(tǒng)由太陽(yáng)能充電鋰電池后,，再供電整個(gè)系統(tǒng),；結(jié)合ZigBee自行無(wú)線網(wǎng)絡(luò)組網(wǎng)、自行愈合,、低功耗和低成本特性,；實(shí)時(shí)監(jiān)測(cè)和記錄土壤濕度信息，采集節(jié)點(diǎn)采集土壤濕度并經(jīng)互聯(lián)網(wǎng)上傳服務(wù)器,，自動(dòng)控制系統(tǒng)依據(jù)土壤濕度自動(dòng)調(diào)節(jié)灌溉量,。試驗(yàn)結(jié)果表明，該系統(tǒng)運(yùn)行穩(wěn)定,，丟包率低,，能準(zhǔn)確監(jiān)測(cè)土壤墑情信息，并由自動(dòng)灌溉系統(tǒng)將土壤濕度保持在適合植物生長(zhǎng)最佳范圍中,，適用于山地果園。

    Abstract:

    In order to improve the efficiency of water utilization in mountain orchards, an automatic irrigation control system based on soil moisture was designed. The system was composed of an S3C2440 ZigBee gateway, several CC2530 soil moisture sensing nodes and irrigation controlling nodes. In addition, solar batteries were applied to provide extra power and recharge lithium batteries. Using the self organized ZigBee network, the gateway collected and updated soil moisture data to internet server for decision support. Therefore, irrigation process was handled according to soil moisture. The system test in a mountain orchard showed that the wireless network had a low packet loss rate(less than 15%), and maintained soil moisture in a suitable range (above 18%) for plant growth.
