Abstract: A monitoring system based on the sensor networks and transfer technology of Zigbee was designed for orchard environmental factors such as temperature, Carbon dioxide concentrations, light intensity, soil humidity and so on. The datas were transferred from orchard to the controller system Nia the sensor by using Zigbee technology. The final results were presented to the manager of orchard. It realized the multi-sensor fusion system based on remote monitoring. The system hardware unit included microcontroller(MSP430F149), sensor design and RF chip(CC2420), the experiments proved that the system was stable, could meet the expected purpose. It also could expand more indexes and meet the need of orchard management.
Key words: orchard environment; sensor network; Zigbee; real-time monitoring
隨著現(xiàn)代信息技術(shù)、通訊技術(shù)、農(nóng)業(yè)技術(shù)等一系列高新技術(shù)的高速發(fā)展,推進(jìn)了農(nóng)業(yè)物聯(lián)網(wǎng)時(shí)代的來臨。所謂農(nóng)業(yè)物聯(lián)網(wǎng),即通過各種信息傳感設(shè)備,采集各種農(nóng)業(yè)生產(chǎn)需要的信息,與互聯(lián)網(wǎng)結(jié)合形成的一個(gè)巨大網(wǎng)絡(luò)。最終實(shí)現(xiàn)所有物品與網(wǎng)絡(luò)的連接,方便識(shí)別、管理和控制。無線傳感網(wǎng)絡(luò)是集信息采集、信息傳遞、信息處理于一體的綜合智能信息系統(tǒng)[1]。
果園環(huán)境是直接影響果樹產(chǎn)量的重要因素之一。只有在最佳的環(huán)境條件下,果樹的品種優(yōu)勢(shì)才能充分發(fā)揮。隨著規(guī)模化、智能化、精細(xì)化農(nóng)業(yè)的發(fā)展,對(duì)果園參數(shù)實(shí)時(shí)監(jiān)控日益顯著。在果園中引入Zigbee技術(shù)后,以其靈活而強(qiáng)大的組網(wǎng)功能,可以實(shí)現(xiàn)對(duì)果樹環(huán)境狀況進(jìn)行動(dòng)態(tài)監(jiān)控;達(dá)到滿足果樹的營(yíng)養(yǎng)需求、節(jié)約用水、監(jiān)測(cè)果樹病蟲害的目的,最終實(shí)現(xiàn)果樹栽培中各項(xiàng)關(guān)鍵參數(shù)更精確的控制。……
