【摘要】：科學(xué)的控制植物生長環(huán)境在當(dāng)今農(nóng)業(yè)生產(chǎn)活動(dòng)中顯得尤為重要。目前國內(nèi)大棚內(nèi)的環(huán)境一般靠人工管理來調(diào)節(jié)農(nóng)作物的生長,人工管理成本高且不能實(shí)時(shí)精準(zhǔn)的考查大棚內(nèi)環(huán)境。為了實(shí)現(xiàn)農(nóng)作物生長的優(yōu)質(zhì)和生產(chǎn)的高效,開發(fā)出調(diào)節(jié)作物環(huán)境系統(tǒng)是非常有必要的。為了解決這個(gè)問題,本論文設(shè)計(jì)并實(shí)現(xiàn)了一種經(jīng)濟(jì)又實(shí)用型單點(diǎn)實(shí)時(shí)監(jiān)測(cè)與控制大棚環(huán)境系統(tǒng)。該系統(tǒng)能夠?qū)崟r(shí)監(jiān)測(cè)大棚內(nèi)的光照強(qiáng)度和土壤濕度,并且能夠根據(jù)監(jiān)測(cè)到的情況判斷當(dāng)前環(huán)境是否在植物適宜生長環(huán)境內(nèi),從而作出相應(yīng)決策。該系統(tǒng)有適宜農(nóng)作物生長的光照和濕度的臨界值,并且有按鍵檢測(cè)調(diào)節(jié)臨界值,能夠針對(duì)不同作物的適宜環(huán)境設(shè)置臨界值。本文涉及的工作主要有以下幾個(gè)方面:(1)設(shè)計(jì)了監(jiān)測(cè)和控制大棚環(huán)境系統(tǒng)整體的功能框架,選擇STC89C52單片機(jī)為主控,光敏電阻和YL-69傳感器采集數(shù)據(jù)傳送到ADC0832處理,ADC0832將數(shù)據(jù)傳送給單片機(jī),單片機(jī)對(duì)相應(yīng)負(fù)載作出開關(guān)決策,同時(shí)將數(shù)據(jù)傳送到LCD1602顯示。Altium designer為硬件開發(fā)工具,用于設(shè)計(jì)系統(tǒng)硬件電路圖,實(shí)現(xiàn)元器件之間引腳的連接。Keil u Vision3為軟件開發(fā)工具,用于編寫軟件程序,實(shí)現(xiàn)各部分的功能。(2)使用仿真工具PROTEUS為設(shè)計(jì)的硬件電路和軟件進(jìn)行仿真測(cè)試,驗(yàn)證設(shè)計(jì)系統(tǒng)的有效性。(3)對(duì)焊接好的電路進(jìn)行斷電、通電、錄入程序調(diào)試。仿真驗(yàn)證了本系統(tǒng)的有效性。針對(duì)不同的作物,該系統(tǒng)可以快速準(zhǔn)確的對(duì)大棚內(nèi)的環(huán)境進(jìn)行監(jiān)測(cè)和控制,從而為作物提供適宜的生長環(huán)境。多點(diǎn)數(shù)據(jù)采集系統(tǒng)以及實(shí)現(xiàn)網(wǎng)絡(luò)連接控制的上位機(jī)在進(jìn)一步設(shè)計(jì)實(shí)現(xiàn)中。
[Abstract]:It is very important to control the environment of plant growth scientifically in the current agricultural production. At present, the domestic greenhouse environment generally depends on manual management to regulate the growth of crops, and the labor management cost is high and can not be accurately checked in real time. In order to realize the high quality of crop growth and the high efficiency of production, it is necessary to develop a crop environment regulation system. In order to solve this problem, this paper designs and implements an economical and practical single point real time monitoring and control system for greenhouse environment. The system can monitor the light intensity and soil moisture in the greenhouse in real time, and can judge whether the current environment is suitable for plant growth or not according to the monitoring conditions, and make the corresponding decision. The system has the critical value of light and humidity suitable for crop growth, and has the key to detect and adjust the critical value, which can set the critical value according to the suitable environment of different crops. The main work involved in this paper is as follows: (1) the function frame of monitoring and controlling greenhouse environment system is designed, and the STC89C52 microcontroller is selected as the main control. The data collected by photosensitive resistor and YL-69 sensor is transmitted to the ADC0832 processor ADC0832, which makes the switch decision to the corresponding load, and transmits the data to the LCD1602 display. Altium designer as the hardware development tool. It is used to design the hardware circuit diagram of the system and to realize the connection of pins between components. Keil u Vision3 is used as the software development tool to write the software program. The function of each part is realized. (2) the hardware circuit and software designed by PROTEUS are simulated and tested to verify the validity of the design system. (3) the welding circuit is cut off, electrified, input program is debugged. The effectiveness of the system is verified by simulation. For different crops, the system can monitor and control the environment in the greenhouse quickly and accurately, thus providing a suitable growth environment for crops. The multipoint data acquisition system and the upper computer which realizes the network connection control are further designed and implemented.
