【摘要】:農(nóng)作物溫室大棚是一種高密集型的農(nóng)業(yè)生產(chǎn)技術(shù),相對于普通戶外種植,它能提高農(nóng)產(chǎn)品的產(chǎn)量與質(zhì)量。在大棚內(nèi),影響農(nóng)作物生長的主要因素有:溫度、濕度和二氧化碳濃度等環(huán)境參數(shù)。為了支持農(nóng)業(yè)精細(xì)化耕作,進(jìn)一步提高生產(chǎn)效率,降低生產(chǎn)成本,需對溫室大棚內(nèi)的環(huán)境參數(shù)進(jìn)行隨時監(jiān)測和控制,確保農(nóng)作物處于適宜它們生長的環(huán)境中。傳統(tǒng)溫室大棚監(jiān)控系統(tǒng)一般采用有線連接方式,存在著布線難度大、成本高和維護(hù)不便等問題。近年來,隨著無線傳感器網(wǎng)絡(luò)研究領(lǐng)域的不斷進(jìn)步,IEEE 802.15工作組提出了Zigbee協(xié)議;赯igbee協(xié)議組建的短距離無線通信網(wǎng)絡(luò),具有自組織、低復(fù)雜度、低功耗、低成本和高數(shù)據(jù)傳輸率等優(yōu)點,適用于自動控制和遠(yuǎn)程控制領(lǐng)域。在此應(yīng)用背景下,本文設(shè)計了一套基于Zigbee技術(shù)的農(nóng)作物溫室大棚監(jiān)控系統(tǒng)。本文將農(nóng)作物溫室大棚監(jiān)控系統(tǒng)分為兩大子系統(tǒng),分別是:棚內(nèi)下位機(jī)子系統(tǒng)和遠(yuǎn)端上位機(jī)子系統(tǒng)。棚內(nèi)下位機(jī)子系統(tǒng)由Zigbee節(jié)點和傳感器組成,負(fù)責(zé)實現(xiàn)數(shù)據(jù)的采集與傳輸。數(shù)據(jù)傳輸采用了Zigbee和GPRS兩種無線通信技術(shù),其中Zigbee技術(shù)負(fù)責(zé)將終端節(jié)點中的數(shù)據(jù)傳輸至協(xié)調(diào)器節(jié)點中,GPRS技術(shù)負(fù)責(zé)將協(xié)調(diào)器節(jié)點中的數(shù)據(jù)發(fā)送至遠(yuǎn)端上位機(jī)。上位機(jī)模塊利用組態(tài)王軟件工具實現(xiàn)了PC端的數(shù)據(jù)獲取與監(jiān)控功能,并在此基礎(chǔ)上進(jìn)行二次開發(fā)。在棚內(nèi)下位機(jī)子系統(tǒng)方面,論文完成了農(nóng)作物溫室大棚監(jiān)控系統(tǒng)的硬件設(shè)計,包含:Zigbee模塊選擇;Zigbee數(shù)據(jù)采集節(jié)點的傳感器選型與設(shè)計;節(jié)點通信模塊與組網(wǎng)關(guān)鍵技術(shù)研究。在遠(yuǎn)端上位機(jī)子系統(tǒng)方面,論文完成了了農(nóng)作物溫室大棚監(jiān)控系統(tǒng)的軟件設(shè)計,包含:監(jiān)控選件開發(fā)環(huán)境的選擇;監(jiān)控軟件界面與功能設(shè)計;串口通信的設(shè)置。論文解決了農(nóng)作物溫室大棚環(huán)境監(jiān)控系統(tǒng)中的軟硬件設(shè)計與選型、Zigbee節(jié)點模塊整合、組網(wǎng)傳輸和編程實現(xiàn)等技術(shù)難題。經(jīng)實驗證明,本系統(tǒng)可實時獲取溫室大棚中的環(huán)境參數(shù)數(shù)據(jù),工作表現(xiàn)穩(wěn)定,可滿足實際需求。最后,對已完成工作進(jìn)行總結(jié),并對將來工作進(jìn)行展望。
[Abstract]:Crop greenhouse greenhouse is a kind of high-intensive agricultural production technology, it can improve the yield and quality of agricultural products compared with ordinary outdoor planting. In the greenhouse, the main factors that affect the growth of crops are: temperature, Environmental parameters such as humidity and carbon dioxide concentration. In order to support fine farming, further improve production efficiency and reduce production costs, environmental parameters in greenhouse should be monitored and controlled at any time. In recent years, the traditional greenhouse monitoring system generally adopts wired connection mode, which has the problems of difficult wiring, high cost and inconvenient maintenance. With the development of wireless sensor network research field, the Zigbee protocol has been proposed by the IEEE 802.15 working group. The short-range wireless communication network based on Zigbee protocol has the advantages of self-organization, low complexity, low power consumption, low cost and high data transmission rate. It is suitable for automatic control and remote control. In this application background, this paper designs a set of crop greenhouse greenhouse monitoring system based on Zigbee technology. In this paper, the crop greenhouse greenhouse monitoring system is divided into two subsystems. The system is composed of Zigbee node and sensor, which is responsible for data acquisition and transmission. Data transmission adopts two wireless communication technologies, Zigbee and GPRS. The Zigbee technology is responsible for transmitting the data from the terminal node to the coordinator node, which is responsible for sending the data from the coordinator node to the remote host computer. According to the acquisition and monitoring function, The hardware design of the monitoring system of crop greenhouse is completed, which includes the sensor selection and design of the selection of Zigbee data acquisition node in the 1: Zigbee module. Research on the key technologies of node communication module and networking. In the aspect of remote host computer subsystem, the paper has completed the software design of crop greenhouse greenhouse monitoring system, including: the choice of monitoring and selecting development environment; Monitoring software interface and function design; serial port communication setting. The paper solves the technical problems of hardware and software design and selection of Zigbee node module integration, network transmission and programming realization in the environment monitoring system of crop greenhouse. The system can obtain the data of environmental parameters in greenhouse in real time, the performance of the system is stable and can meet the actual needs. Finally, the completed work is summarized, and the future work is prospected.
